No stealing or publishing this story without the author's consent. Thanks! Author's note: This was a story I'd written several years ago and figured I'd just get it out there while I'm working on a bunch of others. It takes a little while to get going, but the sex evetually does arrive. :) Kaylee and Mandi were twins. They had a relatively normal childhood, and although they were not quite fourteen, they were growing up quite fast. Kaylee was the more adventurous of the two, and although the girls traveled in the same social group, Kaylee tended to be the more popular one. Both got plenty of attention from boys at school, but Kaylee was the only one to have had a boyfriend. It was only once, and it only lasted about a month. Lately, Kaylee had been vaguely aware of her developing sexuality. She and her friends talked about sex constantly and were always wondering what it would be like and who they wanted to do it with. Kaylee never really knew the answer to the latter question, so she always made up a boy or went along with whoever seemed to be most popular at the time. Kaylee didn't consciously realize it at the time, but she had been noticing other girls more and more often. She would often catch herself looking at her friends' breasts, or the way their jeans hugged their butts. However, she tended to dismiss these thoughts as harmless. What did strike Kaylee as odd, however, was when she started stealing these glances at her twin sister. Whenever she caught herself doing it, she would mentally kick herself and look away. Pretty soon she began to wonder why it was happening so often. It was strange - Mandi looked just like she did. She could understand looking at other girls like her friends - maybe to compare her bodies to theirs. But with Mandi there was no comparison. They were identical. It got to the point where Kaylee began wondering what Mandi looked like naked. They had seen each other naked many times before as little girls, but not in at least three or four years. Kaylee wondered if maybe this was the reason. Maybe she just wanted to compare her body to Mandi's to see if they were still as identical as they were when they were younger. Still, every time she caught herself staring at her sister, she felt as if it was wrong somehow and she shouldn't be doing it. Then one night Kaylee had an inexplicable dream where she did get to see Mandi naked. In her dream, she focused intently on all the parts of her sister she doesn't normally see - her breasts, her crotch, and her bottom. In her dream, Kaylee simply couldn't stop examining these parts of her sister - particularly her smooth, round bottom. It was so real she could almost feel the warmth and smoothness of her sister's skin. She felt her temperature rising, and she felt wonderful - better than she had in a long time. This wonderful feeling seemed to get better and better, increasing in its intensity the more she studied her sister's naked body. It got to the point where she could barely take it anymore. Everything was rising and becoming more and more intense. Then, suddenly, she woke up. Immediately, she realized she was hot and sweaty, and breathing heavily. What had just happened? As she lay in bed staring at the ceiling in the dark, she desperately wished she could return back to her dream. She had never felt such incredible feelings before. Then with a shock, she realized her dream had been about Mandi. Specifically, Mandi's naked body. Why did thinking about Mandi naked make her feel that way? What were those things she was feeling? And why did she so desperately want to return back to them? Frustrated, she rolled over on her side, more confused than she'd ever been. As she did so, she suddenly felt a funny sensation between her legs, like something was oozing out of her. Panicking, she quickly shoved her hand down her panties and was shocked to discover a slick wetness all over her crotch. The back of her hand was wet too, as it had seeped through her panties. Quickly, she threw off her covers and turned on her bedside lamp. Sitting up and scooting back, she was again surprised to see a small damp area on her mattress. This had never happened to her before. What was it?! Then, suddenly, the information from the sex education video she saw at school started coming back to her. With yet another shock, she realized that this was the result of sexual arousal. Had it all been because of the dream? A dream about her own SISTER?! Kaylee didn't know what to make of any of this. She had never been so confused in her life. Why did a dream about her own sister make her sexually excited? But what really threw her for a loop was HOW excited it had made her. She had never come close to having those feelings before. Ever. Not with her boyfriend, and not when she was talking about boys with her friends. Was this normal?! Of all the people that she could have been sexually attracted to, why did it have to be her own sister?! Kaylee turned her lamp back off and crawled back into bed. She grabbed some tissues from her nightstand and stuffed them in her panties in an attempt to soak up some of the mess. Then she flopped back down on her pillow, her mind spinning. She was still worked up from the dream. She desperately wanted to go back there. Those feelings - there was nothing like it. It was the most powerful and wonderful thing she had ever experienced. But was she prepared to start thinking about Mandi again in that way? That was gross, wasn't it? She decided to try it, as an exercise. Think about Mandi naked... Think about Mandi naked... her boobs... her butt... Oh God, her butt! Immediately, Kaylee felt that hot rush of excitement wash over her again. Then she snapped out of it and her heart sank. It was confirmed. She was sexually attracted to her own sister. What would she do?! What COULD she do? Kaylee didn't get any more sleep that night, despite numerous attempts to do so. In the morning she bumped into Mandi on her way to the shower. It was like a bolt of electricity had run through her. She stammered an apology and suddenly realized she was nervous around Mandi! This was impossible! They were as close as twins could be, and Kaylee realized it wouldn't be long before Mandi realized something was up. What would she say? How could she tell her twin sister that she had the hots for her? The school day was a blur. Mostly because Kaylee couldn't stop thinking about that dream she had and the potential consequences of it. Was she forever doomed to live with this secret? Was it permanent? Would it ever go away? It's not like Mandi was ever going to not be a part of her life. Would she always secretly have these feelings whenever she saw her? What was the alternative? Could she tell Mandi? What would Mandi say? No, telling her would be too much. She couldn't do that. These thoughts ran through her head all day, torturing her. When their mother picked them up from school, Kaylee sat in near silence the whole way home. For once, Mandi was the talkative one. Their mother asked Kaylee if something was wrong and Kaylee just mumbled that she didn't sleep well last night and was really tired. Which was true. When she got home, she went to her room and closed the door. She just wanted to go to sleep so she could dream about Mandi again. She desperately craved to feel that intensity again, if just for a brief moment. Then she thought, maybe she didn't have to go to sleep to feel that way again. She remembered that that sex education video had talked about masturbation. She had always thought of the idea of masturbation as gross and unappealing, but now it suddenly didn't seem that way anymore. It seemed to have a purpose - a very good one - and she suddenly understood why the video had talked about it, and said that there was nothing shameful about it and that it was a very normal thing for girls to do. Could she do it? Could she masturbate while thinking about her own sister? The thought was still strange to her, but the desire to feel that overwhelming bliss again was far stronger. It still seemed weird to her though - touching herself. It felt kind of dirty. Besides, she wouldn't really know what to do anyway. Frustrated, she flopped face down onto her bed. Just then, a little tingle shot through her when she hit the bed. Pleasantly surprised, she began to think. She pressed her hips down firmly into the mattress. There it was again! Her thoughts started running faster. Maybe she didn't have to touch herself after all! Looking up, she reached for her pillow and got up on her hands and knees. She placed the pillow on the bed and lowered her hips down onto it and laid down. She sighed with pleasure. But it still wasn't enough. She raised her hips in the air and began to bunch the pillow up into a little ball. Then she lowered her hips back down. Ahhh, this is more like it, she thought. She began to wiggle and rotate her hips around on the pillow and sighed heavily into her mattress. Sparks shot through her body as that familiar sensation began quickly coming back to her. Suddenly she pushed herself up and stood beside her bed, quickly fumbled with the button and zipper of her jeans, pushed them down her legs, and clumsily but frantically began to step out of them. Once they were off and she was just in her panties, she knelt back on the bed, balled the pillow up as best she could, and flopped back onto it, shoving it up into her crotch with both hands. She groaned into her mattress as she began to work her hips around on the pillow, reveling in the sensations. She thought of Mandi, and of her beautiful naked body. She imagined Mandi was underneath her and she was grinding away against her. The sensations increased dramatically and Kaylee felt her temperature begin to rise quickly. She pretended that Mandi was just as into this as she was and that she was crying out Kaylee's name as she panted heavily. She imagined Mandi's body pressed tightly against hers and that she could feel her sister's hips, stomach, and breasts pressed against her own. She imagined her face buried into her sister's warm neck and suddenly she began to wonder what it would be like to kiss her sister. The mere thought sent an intense erotic wave straight to her pleasure center. Kaylee had kissed a boy before, but it was no more than a prolonged peck on the lips. Kaylee now suddenly had the urge to kiss her sister fully open-mouthed. Never before had she had such an urge to put her tongue so deeply and firmly in someone else's mouth. She always thought the idea of French-kissing to be kind of gross, but now she wanted to taste every inch of her sister's mouth, feel its wetness and take in its heat. She wanted to lock her lips against Mandi's with her tongue deep in Mandi's mouth and Mandi's tongue deep in hers. This idea of both of them having their tongues in each other's mouths at the same time was incredibly erotic to her. Kaylee humped the pillow hard and urgently, lost in her fantasy of making love to her sister. The sensations were rising again and she could feel herself getting close to that point of extreme intensity. She imagined Mandi wrapping her arms around her and holding her tight. She humped faster. Harder. She had never felt so close to Mandi in all her life. It was as if this was meant to be. She felt the sensations come to a peak and she gritted her teeth as she jammed the pillow tightly into her crotch and ground her hips down hard against it. Wave after incredibly intense wave flooded her body and she convulsed in rapid jerks and spasms as ultimate bliss seized her body. Then her mind went blank. When she opened her eyes again, she was still lying on her bed, pillow bunched up under her crotch, and hands underneath the pillow. She had no idea how long she'd been out, but it couldn't have been more than a few minutes. She began to pull her hands out from underneath her, noticing that they felt like lead weights. She began to lift her upper body and realized that she had drooled all over her mattress. Oh well. Then she began to sit up and her hips came off the pillow. The first thing she noticed was the smell. It hit her in the face like a ton of bricks. Then her eyes widened as she noticed a very large dark stain on her pillow. She placed her hand on it and it came away wet. Not damp, but wet. 'Oh my God,' she thought. 'I've just ruined my pillow.' Then she touched her hand to her crotch, surprised at how sensitive it was, and realized that it, too, was sopping wet. 'Wow,' she thought. 'I guess I'm not using this pillow for anything else.' As she cleaned up her bed, Kaylee realized that her mind was in a constant state of wonderful bliss. Everything seemed right with the world. Everything was beautiful. If this was what masturbation had to offer, she considered herself hooked. ******************************************************* Kaylee made masturbation part of her regular routine. Nearly every day when she got home from school - time permitting - she went to her room, stripped to her underwear, and humped her pillow, imagining she was with Mandi. It was heavenly. This became her favorite part of the day and she looked forward to it constantly, desperately awaiting the time where she could spend her private thoughts on her twin sister, pretending they were making love. Sometimes she would switch positions, lying on her back with her legs wrapped around the balled-up pillow as she pumped it into her with her hands, imagining that Mandi was on top of her. Or she would sit up on her knees and stuff the pillow between her legs, riding it like a horse. She fantasized that Mandi liked different positions, and this often got her off faster than usual. Through the normal course of the day, things were a bit more difficult. She would still talk to her sister, of course, but more often than not she would find herself becoming aroused and staring at various parts of Mandi's body. When this happened, she couldn't focus and her conversation became awkward and she excused herself, often to go masturbate. She knew this behavior must seem odd to Mandi. It had been a few weeks now, and on a few occasions Mandi even asked her if something was wrong. She just dismissed it though, saying she was tired and had a lot of homework to do. But Kaylee knew she couldn't keep doing this. Sooner or later Mandi was going to press her. Then what would she say? That she's sexually attracted to her and wants to make love to her? That was pretty much out of the question. As the days went by, Kaylee's feelings about her sister continued to grow. She was staring at her more often and for longer periods of time. One morning Kaylee was getting ready for school just as Mandi had gone into the bathroom to use the shower. Not long after Kaylee heard the door close, she heard it open again and then heard the hall closet door open. Curious, she peeked around the corner and saw Mandi in her spaghetti strap nightshirt - with no bottoms! She had just grabbed a washcloth and turned to go back toward the bathroom, giving Kaylee an incredible view of her smooth, bare bottom, so perfectly rounded and curved. A jolt of excitement shot through Kaylee and just then, Mandi turned her head in Kaylee's direction. Quickly, Kaylee darted back into her room, out of sight. That glimpse of Mandi's bottom had pushed Kaylee into overdrive. For weeks now, she had been fantasizing about what her sister looked like, and now not only had she gotten her wish, but she had seen the very part she desired to see most! And oh, it was so exquisite! It was better than she ever imagined it could be. Quickly she grabbed her pillow, jumped on the bed, and furiously began humping it, imagining that she was humping Mandi's soft bottom. She came faster and harder than she had in a long time. As she lay there on her bed, panting in the afterglow of her orgasm, images of Mandi flashed through her mind. Sometimes after her orgasms, she would feel shame and disgust, as if what she had just done was wrong. But now all she could think about was Mandi. Kaylee wished she were here, holding her. She wanted to be close to Mandi again and share these experiences with her. She wanted to love her. And then it hit her like a ton of bricks. She realized she was in love with Mandi. She was in love with her own twin sister. It all made sense - the strong emotions, the obsessions, the lingering stares, the desire to kiss her... there was no other explanation. She was in love. Strangely, this realization didn't disgust or put off Kaylee. In fact, she felt relieved. She was glad to have finally figured out what was going on. And now there was no doubt in her mind that she had to do something. Love wasn't something you could just suppress and pretend didn't exist. But what could she do? Telling her would be too much for Mandi to hear and could be disastrous, and doing anything without Mandi knowing how she felt was unthinkable. Above all, she just wanted to be close to Mandi. To hold her, smell her hair, kiss her soft lips. Then she thought, maybe that was it. Maybe if she could get Mandi to kiss her, the passions and emotions would come across in the kiss and she would understand how she felt. It was worth a shot. But how would she do it? It was Thursday, and all day long Kaylee had been plotting to think of a way that she could get Mandi to kiss her. The thought was so erotic it was giving her chills and kept her nerves on edge all day. As she went to bed that night, she thought she had figured it out. Tomorrow was Friday, and that would be a perfect opportunity. She prayed that Mandi would go along with it. Kaylee had woken up late Friday morning and cursed herself. She had to rush to get ready for school so she wouldn't make Mandi late. There was no time to talk to her that morning. All day at school she ran over the plan again in her mind, checking for anything that might go wrong. Then as they got home from school and their mother went to the kitchen, Kaylee pulled Mandi aside. "Hey," Kaylee said in a hushed tone. "Do you wanna... hang out tonight?" "Hang out? What do you mean?" Mandi looked confused. "After mom and dad go to bed," Kaylee said. "There's this... thing... I'm kinda working on, and I thought maybe you might wanna help." "What kind of thing?" Mandi said, still confused. "Just come on. It'll be fun, I promise," Kaylee said. "Mom and dad usually go to bed around 11, so meet me in the guest bedroom at 11:30." "Um, okay," Mandi said. "Cool. See you then," Kaylee said and went off to her bedroom. The rest of the day was torture for Kaylee. She made a point of not masturbating - difficult as it was to do - because she wanted to be fully excited and energized for her encounter with Mandi later. Her heart pounded and her nerves were on edge all evening. Finally, it came time to get ready for bed. The girls cleaned up and went to bed first, around a quarter after 10, and Kaylee waited patiently in her room for her parents to stop moving around the house and go to bed. Much to her delight, she heard her parents head off to their bedroom EARLY - around 10:45. Every nerve in her body was on fire as she heard her parents' bedroom door close. She waited ten minutes, then quietly opened the door to her room and softly padded down the hallway to the guest bedroom. This was the perfect room for the girls to meet since it was at the opposite end of the house from their parents' room. Once Kaylee was in the room, she closed the door and turned the bedside lamp on. She looked at the clock. It was only 11:00. She cursed herself for telling Mandi 11:30. She had never been so impatient in her life. Her heart was pounding and her nerves were on edge. She desperately wanted to touch herself, but she promised herself she wouldn't. A few times the urge got too strong and she pressed the heel of her hand to her crotch and ground it around, but she always pulled away quickly. She told herself it was just to relieve some of the tension. But all it did was cause her liquids to seep out into her panties. Finally she heard a hand on the door handle and heard it slowly turn. She jumped, startled. Then she told herself to breathe and to calm down. When Mandi entered the room, her heart skipped a beat. She was dressed in her spaghetti strap top and light blue panties. Kaylee smiled at her sister and as Mandi turned to close the door again, Kaylee caught an eyeful of her sister's tight, panty-clad bottom. Her heart pounded even faster. Kaylee was sitting in the middle of the bed and Mandi walked up to the edge of it. "So what's this all about?" Mandi said quietly, tucking a few strands of hair behind her ear. "Here, come sit with me," Kaylee said, patting the spot next to her on the bed. Mandi climbed up on the bed and sat next to her sister. They looked at each other. There was an awkward pause, and then Kaylee burst into giggles. "What?" Mandi said, grinning. "Nothing, nothing," Kaylee said. "It's just... well this is just kinda weird. You're probably gonna think I'm really weird for wanting to do this, and you totally don't have to if you don't want to," she said, desperately hoping that Mandi would want to. "What? What is it?" Mandi asked, really curious now. "Well... um... you know how I went out with James a few months ago, right?" Kaylee said. "Yeah..." Mandi said. "Why, are you guys getting back together?" "NO!" Kaylee said, a little too loudly. "No, no, no, nothing like that. I mean, he's a nice guy and all, but... no." Kaylee paused to take a breath. "It's just that... we... never really... kissed... you know?" "Really? I thought you did," Mandi said. "Well, I mean, we did kinda... but it wasn't really kissing. Just like, kinda a peck on the lips, y'know? I mean, it really wasn't much of anything." "Well, it's more than I've done," Mandi said. "Exactly!" Kaylee said. "And, you know, I was thinking... we should know what to do... you know... for when we get boyfriends and all that. So I was thinking maybe we could, like... practice on each other." "What?!" Mandi said, surprised and a little confused. "See, I knew you would probably think it's too weird. It's just..." Kaylee said, "...I've just really been curious of what it's like, and I really trust you and everything. I think it would be kinda fun." Mandi's eyes widened, then she was quiet for a bit. "Um, I dunno. That IS kinda weird," she said. "Yeah, I guess it is," Kaylee said. "But it's not like it would mean anything. We could just close our eyes and pretend we were kissing a boy." Mandi sat and stared at the comforter. "I dunno..." she said, biting her lower lip. Kaylee sighed. She would try another angle. "I know," she said. "I figured you'd think it was too weird." "Well, I dunno," Mandi sighed. "I mean... it's not like it would mean anything, right?" Kaylee bit her lip and nodded. "You promise you won't tell anyone about this?" Mandi said. "Cross my heart and hope to die," Kaylee said, her heart suddenly leaping with joy. Mandi sighed. "Okay. I guess so." Kaylee giggled with glee and threw her arms around her sister. "Thanks Mandi! I promise it'll be fun. You won't regret it." She then pulled back and looked at her sister. There was an awkward silence. Mandi looked down. Then Kaylee said, "Hey." Mandi looked up. Then Kaylee began to lean in towards her. Instinctively, Mandi leaned backwards. Then Kaylee leaned back. "Sorry," Mandi said, giggling a little. "It's just... this is a little weird. Like, you're my sister and all." Exactly! Kaylee thought. "Well, how about we turn the lights off?" Kaylee said. "Then it'll be easier to pretend we're someone else." Kaylee, of course, had no intention of pretending Mandi was someone else. "Um... okay," Mandi said. Kaylee leaned over and switched off the lamp on the nightstand. The room went dark. Then she sat back up on the bed. In the darkness, she couldn't see Mandi, even though she was right in front of her. She began to lean forward a little and could hear Mandi breathing. Then she leaned closer, and closer still, and she knew Mandi was close. Her nerves were on edge. She leaned closer, closer... and then their heads bumped. Both girls immediately broke out into giggles. After a minute or two of hysterical giggling, Kaylee said, "Sorry! It's hard to see you in the dark." More giggles. "Okay. Okay, ready? Here's for real this time." Kaylee then leaned forward again, slower this time, and slower still as she felt herself get closer to her sister. She held herself still, listening for Mandi's breathing. She turned closer in that direction. Soon she could feel Mandi's breath on her face. Her heart was pounding like crazy. This was it. The moment she had been waiting for. She held herself still, allowing herself to savor the closeness of her sister and the feel of her warm breath. She waited, and the longer she did, the hotter she became because Mandi did not back away. She knew Mandi could feel her closeness as well. Then she leaned slowly forward and felt her hair brush against Mandi's. Mandi flinched, but did not back away. Kaylee moved slowly in the direction of Mandi's breath, toward her lips. Closer... closer. Mandi's breath was upon her own. The electricity between them was tangible. She tilted her head. Slowly, her lips brushed her sister's. Then on impulse, she leaned in firmly, pressing her soft lips against Mandi's and tilting her head to press her mouth fully against her. She sighed deeply, holding the kiss, waiting to see what Mandi would do. Mandi stayed where she was, so Kaylee lost herself in the bliss, kissing her sister firmly and passionately, opening her mouth and sliding her lips across her sister's at an angle. As much as she wanted to passionately devour her sister's mouth, Kaylee kept her composure, staying gentle with Mandi so as not to scare her. But oh, it was hard. This was the most wonderfully exquisite - not to mention intensely erotic - sensation Kaylee had experienced in all her thirteen years. Her sister's warm, wonderfully soft lips were pressed against her own. Keeping her lips on Mandi's, she moved her body closer to her sister and placed her hand on Mandi's thigh. Instinctively, she leaned into Mandi, kissing her deeper, and decided to venture her tongue out and pushed the tip of it into Mandi's mouth. She did not seem to object, so Kaylee pushed her tongue a little further, until she touched Mandi's with it. She had never tongue-kissed anyone before and she was excited by the sensations of her sister's tongue. It was wet and slimy and covered with tiny little bumps. And it moved constantly - she could feel tiny little muscle movements all over her sister's tongue. It never stayed still. She thought of it as a game and playfully tried to chase her sister's tongue with her own, touching it as often as she could and opening her mouth wider over her sister's to keep their tongues in contact. Her goal was to lick across the full length of her sister's tongue, and a shiver ran through her each time she accomplished this. Fireworks went off in Kaylee's head. This was more perfect than she ever could have imagined. Her open mouth fit perfectly against Mandi's - a mirror image of her own. It felt so perfect and so right to be kissing her twin sister - it was like they were made for each other. Their lips were locked so firmly and sweetly, Kaylee couldn't imagine a more perfect kiss. Kaylee instinctively slid her hand up Mandi's thigh, over her hip, and up her side. Kaylee leaned in more, wanting to be closer to her sister. She could feel Mandi's body heat now inches from her own. Her right hand went to Mandi's hip while her left circled around and up Mandi's back. She pulled Mandi closer to her and began to slide her right hand up Mandi's side, closer to her breast. She desperately wanted to feel her sister there. But just before she did, Mandi pulled her head back with a small grunt. Their kiss broke, and as it did, Kaylee could feel a strand of Mandi's saliva stretch between their mouths. She immediately licked where it collected on her lower lip. Both girls were panting heavily. Kaylee suddenly became aware of her actions and Mandi's reaction to them. She blushed, glad that it was dark. "Sorry," she said, leaning back and sitting upright. "I guess I got a little carried away there." Mandi just panted for a few seconds. "Yeah," she finally said, "that's... that's okay." Kaylee panted for a little longer, catching her breath. She was incredibly worked up. "Wanna try again?" she said, starting to lean forward. Mandi leaned back, away from Kaylee. "Um... actually..." she said, "I think I'm getting kinda tired. Wanna try and get some sleep now?" Kaylee was shocked. Her heart sank. Did Mandi not like it? Why did she go along with it? Why did she kiss her back? She decided not to push her. "Um... okay... I guess so." With that, Mandi rolled back the covers on the bed and began to climb between them. She settled in on her side, facing away from Kaylee. Kaylee's mind was a swirl of thoughts and emotions. She didn't know what else to do but climb under the covers and lie down next to her sister. She was incredibly frustrated. She had never been so worked up in her life. Her heart was pounding and moisture was seeping into her panties. She didn't know what to do. They laid there for a minute or two before Kaylee spoke. "So what did you think?" she asked. "Was it fun?" "Um, yeah, it was fun," Mandi said. "I'm just really tired." Then she yawned. Tired?! Kaylee thought. How could Mandi be tired? Kaylee lay there, her mind and body swirling. What had just happened was heavenly! It was the most beautiful, erotic, and amazing thing that had ever happened to her. It felt so right. So incredibly right. This confirmed everything Kaylee had been feeling. Her heart swelled as she realized she was in love. How could she ever express this to Mandi? She wondered if Mandi was really tired and if she was trying to sleep. If she was, she didn't want to bother her. But Mandi wasn't tired. Not by a long shot. She faked her yawn to get Kaylee to stop talking to her so she could think. What had just happened? She had just french-kissed her own twin sister, that's what happened! Was it wrong? Why did she go along with it? She kissed Kaylee for a really long time! Was she a lesbian now? Why did she feel so funny and worked up? What was this feeling? All these thoughts rushed through Mandi's young mind as she lay there. She could still hear Kaylee breathing. Had Kaylee wanted this? She said she wanted to pretend she was kissing a boy, but Mandi wasn't so sure of that. She got REALLY into it. She had almost touched her boob! Boys didn't have boobs! Mandi hoped Kaylee couldn't hear her breathing. She was still catching her breath. Mostly from shock, of course. But what shocked her? The kiss? Or the fact that she was so worked up now? Did she enjoy it? No, that was impossible. She kissed her sister! That was gross! Maybe she just liked the kissing part, and pretending Kaylee was someone else. But wait - did she pretend Kaylee was someone else? Mandi thought back to the kiss. She couldn't remember. It didn't matter though. What was happening to her? Why did she feel so... so... excited?! It was like she craved something else... desperately... but she didn't know what. It felt like her body was on fire. She grabbed a fistful of the bedsheets and squeezed her eyes shut. She felt like crying. This wasn't right. She shouldn't be feeling these things. Kaylee didn't feel these things, did she? She said she wanted to pretend she was kissing a boy! Mandi couldn't understand why she was feeling these things. She must be sick! For nearly 20 agonizing minutes, Mandi lay awake in frustration. She felt like crying, screaming, leaving the room, and... and... wanting more. All she could think about was the kiss. How soft Kaylee's lips had been, how warm they were, how wet and soft her tongue was. She could still taste Kaylee's tongue and saliva in her mouth. She didn't know if she was disgusted by it or excited by it. Her body burned with a need she had never known before. This was absolute torture. She couldn't do any more with Kaylee. Kaylee surely didn't want that, and besides, it would only make Mandi's terrible feelings worse. She wished she'd never agreed to this stupid thing in the first place. Then, suddenly, Mandi heard Kaylee roll over. Oh God. She was still awake! Mandi's heart beat faster. It felt like her body temperature rose further, if that was even possible. She clutched the sheets tight in her fist. Then, suddenly, she felt a hand on her hip. She jerked ever so slightly. She couldn't help it. She was so on edge! And now Kaylee was touching her! She froze in place, holding still for what seemed an eternity. Kaylee's hand did not move. Maybe she was asleep and just flopped her arm over. But as soon as Mandi thought this, Kaylee's hand started sliding up her hip to her side. Shivers ran up and down Mandi's body. It was happening all over again, and this time she couldn't control it. The desire came back, stronger than ever. But desire for what? She didn't know. Kaylee's hand continued sliding up and down Mandi's hip and side. Mandi decided to take a chance. Maybe it would scare Kaylee away. Without warning, she suddenly rolled onto her back. Surprisingly, Kaylee's hand didn't pull away. Instead, it now rested on Mandi's stomach. Still. Mandi laid still, wondering what Kaylee would do. She wondered if Kaylee was looking at her right now, even though she probably couldn't see her in the dark. Then, slowly, Kaylee's fingers spread out across Mandi's flat stomach. Mandi felt the tingles come back and suddenly she realized she was breathing heavily. Oh God. Kaylee could feel her stomach rise and fall with her breathing. There was no hiding it now. The burning was stronger than ever and Mandi lay there, tense. Kaylee's hand moved up toward Mandi's ribcage. Mandi's breath caught in her throat. Kaylee's hand inched upward, toward her boobs. Mandi stayed frozen. It was nearly a repeat of what had happened earlier. Kaylee's hand inched higher, and higher, and finally her finger brushed the base of Mandi's left mound. Mandi let out a shaky breath. Her body was hotter than it ever had been. Just then, Kaylee began to move her hand down, as Mandi's heart sank. But as it moved, newer sensations grew within Mandi. Kaylee slid her hand across Mandi's stomach and down to her abdomen, slowly continuing downward. Mandi was in a near panic. Kaylee's hand moved in the tiniest increments as the tension and excitement within Mandi built to a peak. Kaylee's hand stopped just above Mandi's crotch. She wanted Kaylee to go further, but she didn't dare say so. Then, suddenly, Kaylee's hand pulled away. Kaylee rolled onto her back, pulling her arms in toward her. Mandi was shocked. Why did she pull back?! Mandi was on fire! Was this all just a game? Mandi thought quickly. Kaylee brought her in here. She started the kiss. She even said she wanted to try it a second time. And now she touched Mandi! She was teasing her. All she could think about was Kaylee's kiss, her touch. In a flash, Mandi threw the covers off herself, rolled towards Kaylee, reaching for her face, and pressed her lips to hers, hard. She reveled in the warm, soft feel of her sister's lips, and suddenly wondered if she had made a huge mistake. Almost as soon as she thought this, she felt Kaylee's hands on her, pulling her close, and all thoughts of doubt vanished. They kissed hard and hot, opening their mouths wide and plunging their tongues deep into the other's mouth. Mandi opened her mouth as wide as she could, covering Kaylee's just as Kaylee had covered hers earlier. They burned for each other, their movements clumsy as each tried to press tighter to the other and kiss the other harder and deeper. Neither girl knew exactly what she was doing - just that she wanted to satisfy this burning sensation. Kaylee was on fire, ecstatic that her sister had finally reciprocated. She pulled Mandi close, but it was awkward as Mandi was on her side, facing her while Kaylee was on her back. Kaylee thought about turning on her own side, but in a moment of inspiration, grabbed at Mandi's waist and hips, pulling her upwards. Their mouths remaining tightly locked, Mandi took the hint and started to raise herself up on her knees, but was stopped when Kaylee pulled her sideways. Mandi rolled herself until she was resting on top of Kaylee, her thigh falling between Kaylee's legs. The heat and closeness was unlike anything the girls had felt. Kaylee sighed as she felt Mandi's burning hot crotch rest against her thigh. Mandi must have felt the same because she sighed just as deeply. Instinctively, Kaylee bucked her hips up into her sister's thigh, and less than a second later, Mandi was doing the same to her. They began to push and grind as they kissed, grunting sharply into each other's mouths. Everything was so hot around their hips and thighs - Kaylee was surprised at the intensity of the heat. Kaylee felt an urgent need deep within her and reached around, forcefully grabbing Mandi's round butt, squeezing hard. She groaned hotly into Mandi's mouth, feeling the part of her sister she had desired for so long. Over and over she grabbed handfuls of Mandi's tight, smooth flesh, pushing it down into her as she felt the most incredible sensation building within her. She pumped and thrust her hips as hard as she could against Mandi's thigh, loving the feel of her sister's tight butt in her palms and her hot tongue in her mouth. Suddenly, Kaylee grunted hard, forcing Mandi's hips down tightly against her as she held her lips firmly against Mandi's and began to shudder. "MMPH!... MMPH!" she grunted, quickly moving one hand up to the back of Mandi's head, making sure she didn't pull away from the kiss. Mandi froze, enthralled by the intensity of Kaylee's movements and actions. She pressed herself tight against her sister and held still, feeling Kaylee's body trembling and shaking beneath her. A few seconds passed, and then Kaylee seemed to strain even harder, pushing down on Mandi's bottom with all her might. Suddenly, Mandi was aware of a spreading warmth across her thigh, and after another few seconds, Kaylee grunted loudly and exhaled, her hand on Mandi's head going back to her bottom and pressing firmly. Kaylee then began to rub Mandi's bottom back and forth, encouraging Mandi to move her hips. Mandi quickly took the hint and proceeded to push her hips in rhythm with Kaylee's hands. The sensations building within Mandi's crotch were incredible. Kaylee continued this motion with her hands on Mandi's butt while moving her own thigh in a counter-motion. Mandi's mouth fell open and she lost the ability to multi-task. The sensation was incredible! She let Kaylee do most of the work, only moving herself when she felt the need to add a little pressure. She rocked her hips against Kaylee's thigh gradually harder, and then gradually faster. Soon, she was humping Kaylee with all her might, like a wild animal. There was an intense sensation building - like nothing she'd ever felt before. It was so powerful it almost scared her. Then, somewhere off in the distance, she heard Kaylee's voice whispering to her. "Come on Mandi... come on! You can do it... You can do it!" It was all the encouragement she needed. Mandi dropped her head, her forehead pressing against Kaylee's, her mouth hanging open, and jerked her hips as hard as she could against Kaylee. Then it started - a feeling so powerfully intense, she gasped sharply and held her breath as her body trembled. "Yes, Mandi! YES!" Kaylee whispered hotly to her. Mandi trembled and shook for what seemed like an eternity. She lost all concept of time. All she could feel was bliss. Pure bliss. Then nothing. ************************************************** Mandi awoke as the room began to lighten. Her head was so fuzzy. Where was she? She felt a weight on her chest and looked down to see Kaylee's arm draped across it. In a sudden rush, the events of last night came flooding back to her. She began to panic. Heavily. What had she done?! Horrified, she bolted upright and began to slide away from Kaylee, who mumbled something, but was still obviously asleep. Almost instantly, she became aware of a strange squishy sensation between her legs. She looked down and saw that her panties had a considerable stain all over the crotch. She thrust her hand into her panties and was horrified to feel a slimy gooey-ness there. She pulled her hand out and quickly wiped it on her shirt. Gradually, she became aware that the room had a distinct musky smell to it. Horrified again, she climbed out of bed, her mind reeling. She quietly went to the door, opened it, walked out, closed the door behind her, and went to her room, desperately trying to erase any thoughts of last night. But it wasn't so easy. Last night had been so intense. Mandi still couldn't figure out what had happened to her. It was as if she had no control over her body. What she really couldn't get over though, were the sensations she had felt. They were unlike anything she had ever experienced before. They were so intense she simply couldn't shake the memory of them from her head. She wanted those feelings again. Desperately. But she couldn't bring herself to accept the conditions under which they took place. It was wrong to have done what she did with her sister. It was gross! But why did it have to feel so good? And how did Kaylee feel about it? That shouldn't matter, Mandi told herself. It was wrong and that was that. No matter how good it felt, she would have to try and find a way to forget what happened. But that proved to be more difficult than she thought as well. She couldn't avoid seeing Kaylee that day, and when she saw Kaylee again for breakfast that morning, a sharp pain shot through her that felt good and terrible all at once. Just seeing Kaylee brought all those emotions and sensations back. As difficult as it was, she tried to shake those feelings off and just pretend that nothing had happened between them. Throughout the day, Mandi tried to avoid Kaylee as much as possible. Kaylee would look at her and smile, but that only made Mandi feel dirty. On a few occasions, Kaylee tried to talk to her, but Mandi just ignored her, saying she didn't feel like talking. All day long, Mandi wrestled internally with her feelings. Her body craved those sensations again, but her brain kept telling her they were wrong. What was she going to do?? Finally, evening had arrived and Mandi told herself she did good since she managed to avoid Kaylee most of the day. But now as it got later and later, and it was time to get ready for bed, she got that funny feeling in her stomach again and it only got stronger and stronger. After brushing her teeth and getting into her nighttime panties and t-shirt, she got into bed and tried to go to sleep. But all she could do was stare at the ceiling wide awake and replay the events of last night. How hot everything had felt, how passionate everything was, and how much her body burned to feel it again. For a half hour, she lay awake trying to push these thought out of her mind, but they only got worse and worse. Maybe... maybe if... maybe if she were to do it again tonight, it would make this burning urge go away and she could get some sleep. But that would be wrong! And besides, Kaylee probably wouldn't go for it anyway. "UUUUHHHH!" Mandi grunted, rolling over. She had rarely experienced such an intense frustration. What could she do? Maybe she could just go to the other room and see if Kaylee would even show up. She probably wouldn't. But what if she did? Maybe they could just talk. Or just sleep next to each other. That might be enough. But Kaylee probably wouldn't even come. Grunting again in frustration, Mandi threw the covers off her and quietly got out of bed. She went to her door and opened it. The house was dark. Quietly, she tiptoed down the hall to the other side of the house where the guest bedroom was. As she got closer, the feeling in her stomach intensified. Her body started to get that burning feeling again. She started to think what she was doing was stupid. Kaylee wasn't going to show up. But then she thought if that was the case, she didn't have anything to worry about. So she quietly opened the door and went into the dark room, closing the door behind her. She put her hand on the wall, feeling for the light switch, and suddenly received the shock of her life. "Leave it off," a voice said. Mandi nearly jumped out of her skin. Her heart pounded as she recognized Kaylee's voice and oddly, that didn't calm her down - it only made things worse. The feeling in her stomach got stronger and she felt a hot rush all over her body. "Come here," Kaylee said. Mandi froze. Her body was a flood of emotions. Her body was screaming at her to go to Kaylee. But her brain told her she shouldn't. Her heart pounded faster as she tried to think of something to say. "Kaylee... I -" "Shhh, don't say anything. Just come here," Kaylee said. It was something about the way she said it. Mandi knew right then she lost the ability to argue. With Kaylee or with herself. She walked slowly toward the bed, feeling as if her body was moving without her brain telling it to. As she got closer, she heard Kaylee move over, toward the center of the bed. Mandi got on the bed, sitting down on her knees. She could tell Kaylee was sitting up. Right across from her. Just then she felt Kaylee's hand on her thigh. Her heart pounded and her body burned. She froze, not knowing what to do. She felt Kaylee leaning forward, and soon felt her breath upon her face. Oh God, Mandi thought, every nerve in her body aching. Then she felt Kaylee's lips on hers. Kaylee opened her mouth and so did Mandi. Automatically. Without thinking. They pushed their tongues into each other's mouths and began to kiss each other softly, sliding their tongues across one another's. Mandi felt Kaylee's hands upon her face and from that point on, everything was a blur. Hands grabbed and squeezed, mouths kissed and licked. Clothes were peeled off, but even Mandi couldn't tell which clothes or whose. It was like everything was happening to someone else. Heat was everywhere. It was so intense. Passions built and grew to incredible heights. Mandi felt the sensations build and build to wonderful, beautiful peaks and then fireworks went off. Everywhere. And the heat continued. And then more fireworks. And more fireworks. She couldn't even remember when she fell asleep. *************************************************** This time, waking up was a little easier. She was in the guest bedroom alone. It had all been a dream, she told herself. Her hair was still messy, her clothes scattered everywhere, and there was still an awful dampness and stickiness between her legs, but that didn't matter as much anymore. She had just had a really great dream. That was all. The day went by easier and she found that she could look at Kaylee again, and even talk to her. It was hard at first, because she still felt an inexplicable twinge in her stomach, but she told herself it didn't mean anything. This was Kaylee. Her real life sister. Not someone she had done anything with. That person at night was someone else. Just a dream. Just something to make Mandi feel better and make those terrible burning feelings go away. But she still enjoyed those sensations and that night again, she went back to the guest bedroom to feel them again. Over and over, night after night, Mandi went back, meeting the mystery person who made her feel so incredible. They didn't talk, they didn't see each other, they just made each other feel good. For Kaylee, this was torture. Wonderful torture, but torture all the same. It was like Mandi was two different people. One of them was her passionate lover at night, who would kiss, touch, and caress her, making her feel the most wonderful and exquisite sensations imaginable. But the other was her cold, distant sister by day, who simply refused to acknowledge any of the evening activities. It frustrated Kaylee to no end. She figured she knew what was wrong. Mandi was scared. She didn't want to acknowledge the reality of what they'd become - lovers. Kaylee didn't doubt that Mandi loved her - she was sure she did - but she knew she would never admit it. Unless she was forced to. Kaylee decided she simply couldn't go on pretending like this. She had to know how Mandi felt. She wanted to hear her say it, to admit it. This current situation was no more than a fantasy. A wonderful and glorious fantasy, but a fantasy nonetheless. Something had to change. She resolved to do something about it that very night. ************************************************* That night, Kaylee lay in bed in the guest room, her heart pounding. She knew what needed to be done. She cared so much for Mandi and needed some confirmation from Mandi herself. Suddenly, she heard the door open. Mandi was coming in. Kaylee kept the lights off, waiting for Mandi to come to bed. Slowly, Mandi got into bed and began to take her shirt off. Once her shirt was off, she turned to Kaylee, reaching for her face to kiss her. Kaylee backed away and reached for the lamp on the nightstand, switching it on. She turned back to Mandi, who looked petrified with fear. Mandi froze wide-eyed, looking her twin sister right in the face. She panicked, quickly sitting up and grabbing a pillow to her chest to hide her breasts. "What are you doing?!!" she cried in shock. Kaylee sat up in bed, facing her sister. "Mandi, we need to talk." "Wha-- I don't know what you're talking about," Mandi said incredulously. "I... I don't even know what I'm doing here!" And with that, she started to get up. "Mandi, wait! Please!" Kaylee said, grabbing her sister's wrist, holding her in place. "Please, just listen to me!" Mandi, hearing the pleading in her sister's voice, sat back down. The girls just stared at each other for a few seconds as Kaylee tried to calm herself down. "Mandi, I - I don't quite know how to say this. I... these past two weeks have been the most wonderful and amazing weeks of my life. I've felt things I didn't even know were possible. Every night here in this room I get this amazing warm glowing feeling that's the most beautiful thing I've ever felt. I never, ever want it to end. From the second I wake up in the morning, all I can think about is coming back to this room here at night. This is where everything makes sense to me and feels right - not just right, but perfect. And it's all because of you, Mandi. You make me feel this way. You make me the happiest girl on earth here in this room. But it feels like we're pretending - or maybe that it's not as real as I think it is because we can't look at each other or talk to each other. I want to do that, Mandi - I need to do that. I need to tell you these things and talk about what I'm feeling. And I need to look at you at night and appreciate how beautiful you are... because I love you. I love you harder and deeper than I ever thought was possible, and I need to know if you feel the same way. Because if you don't, then we should stop what we're doing because I can't take it anymore." Kaylee didn't know where all those words came from - they just poured out of her. She was out of breath, tingly all over, and close to tears. She could feel tears coming to her eyes, but she fought desperately to hold them back. She needed an answer. "So," she said, softer now. "Do you love me?" Mandi was stunned. She had never seen Kaylee so emotional. She was pouring her heart out to her. She had to ask herself how she really felt. She was scared. In fact, she was more terrified than she'd been in her life. She didn't know what to say. She definitely didn't want these meetings to stop - on occasion, she'd felt some of those same things Kaylee was describing. She had to admit that to herself. But at the same time, this wasn't right - was it? Mandi could see that Kaylee was on the verge of tears. She had to say something. "I... I think I do," she said, "but... I don't know if this is right... You're my sister." "Who cares if it's right?" Kaylee said, getting more passionate now. "Does it feel right? Does being with me make you happy? That's what should matter. Who cares if we're sisters? In fact, I'm glad you're my sister! I feel closer to you than ever because of this! It's like I'm seeing you in a brand new way. I'm seeing how beautiful you are... and how sexy you are. And that makes me feel AMAZING inside! I've never been as turned on by anybody as I am by you, and that makes me love you even more! And from what we've done so far, every night we've been in this room, I feel an incredible connection to you, and it feels like you have that connection to me too. But I don't want to pretend - I want it to be real. I want the lights on. I want to see you, touch you, explore you. I want to know I'm being with my sister. But I need to know how you feel. I need to know if you feel the same connection with me as I do with you. Do you love me as a sister... and as something more than that?" Mandi swallowed hard. There was no turning back now. This was truth time. She couldn't go on torturing her sister, no matter how much this scared her. She bit her lip and took a deep breath. Then she nodded. Kaylee's eyes sparkled. A smile slowly spread across her face. But this wasn't good enough. "I need to hear it from you," Kaylee said. "I want you to say it." Mandi tensed. She squeezed her pillow tighter. But the look on her sister's face gave her strength. "I... love you, Kaylee. As your sister... and as more than that." Kaylee's grin spread across her entire face. She half-giggled, half-cried as tears streamed down her face. She leaned forward and threw her arms around her sister. She couldn't help it. She cried tears of joy as she felt Mandi's arms wrap around her. "Oh Mandi!" she cried. "I love you so much!" Mandi was surprised as she felt tears in her own eyes. "I love you too, Kaylee," she said. The girls held each other for a long time, feeling the wonderful emotions of their confessions of love flow through their bodies. Soon, Kaylee pulled back and looked at her sister. Both girls' eyes were wet with tears as they smiled at each other. Kaylee felt like she was looking at Mandi for the first time. She could see the love in Mandi's eyes - the recognition that she longed for - that Mandi loved her - really, deeply, romantically loved her. She leaned in and kissed her sister's lips. The kiss was magical. It seemed to ignite a fire deep within the girls as electric charges coursed through their bodies. Their moist lips spread and slid across each other as they kissed actively and passionately. They pushed their tongues forward simultaneously and caressed each other, taking long, deep licks of the other's mouth and tongue. Kaylee reached for the pillow Mandi still held to her chest and pulled it away, tossing it aside. She moved closer to her sister, feeling the heat between them increase as they continued to kiss, both girls remembering back to their first French-kiss with each other. This memory excited Kaylee, and she brought her hands up to her sister's face, holding it as she plunged her tongue deep into Mandi's mouth. Mandi, surprised by her sister's aggressive movements, was also extremely aroused by them and she began to lean backward, placing her arms behind her for support. Kaylee, feeling her sister's movements, pulled back, panting and still holding her face, and looked deep into her sister's eyes with a hunger that completely melted Mandi. "Take off your panties," she said breathlessly and let go of Mandi's face. With that, she quickly pulled off her own shirt and pushed her panties down before Mandi even got hers to her ankles. Once Mandi's panties were off and tossed aside, she lay down on the bed and looked up at Kaylee. Kaylee eyed her sister up and down, getting a good look at her naked form for the first time. "God, you're beautiful," she gasped. Mandi smiled coyly, blushing slightly. "I'm just like you," she said. Kaylee shook her head. "Your skin is softer, your boobs are rounder, and... your kitty is too beautiful for words." Mandi blushed again, still smiling. "My... kitty?" Kaylee nodded. Mandi shyly looked up at her sister with big eyes. "You are so adorable," Kaylee smiled. They stared at each other, Kaylee admiring her sister's form, and Mandi enjoying being admired. When the silence had gone on for a while, Mandi held her arms up to Kaylee in invitation. "I want to try something different," Kaylee said. Previously, they had locked legs and ground into each other's hips and thigh. "Different?" Mandi said. "Just a little," Kaylee said. "Spread your legs." Mandi blushed, biting her lip. Slowly, she spread her legs open. Kaylee thought it was the most adorably sexy thing she'd ever seen. She bit her own lip as her temperature rose, then got on all fours and crawled over Mandi. She put her knees between Mandi's open legs and began to lower her hips down. Their hips came in contact first, and then as Kaylee lowered a little more, she felt Mandi's hot, swollen mound come into contact with her own. "HHHhh!" "Uhhh!" the girls gasped simultaneously as fireworks went off in their bodies. Kaylee settled into her sister's hips and spread her own legs a little to get better contact. Her mouth fell open and she looked right at Mandi as their mounds pressed firmly together. Mandi had an intense expression on her face and Kaylee thought it was the most beautiful thing she'd ever seen. Kaylee was sure her own expression was equally intense. If rubbing themselves against hips and thighs felt good, this direct contact of their genitalia was the most intense thing either girl had felt. The heat alone generated by Mandi's mound was enough to send Kaylee into overdrive. "Oh Mandi!" Kaylee gasped softly, staring into her sister's eyes. Mandi stared back, her breathing shallow. "Ka - Kaylee... Omigod, this... this is..." She trailed off, unable to finish her thought. "I love you, Mandi!" Kaylee said, and began to push her hips into her sister. Both girls' jaws dropped and their eyes rolled back in their heads. Mandi reached for Kaylee's arms and gripped them tight as Kaylee thrust against her. The girls couldn't escape the thought that this was sex - real sex. Direct genital contact, lights on in the room, looking at each other, conscious of what was going on. Kaylee reveled in the fact that she was having sex with her sister and concentrated on every detail of what she was doing. She moved herself around, feeling for Mandi's clitoris, and when she felt the hard little bulge press into her, she ground herself against it, working her hips in tight little circles. Mandi's eyes flew open. "UH! Ohmig...! Kaylee!" Kaylee's heart pounded and her body tingled. She was on fire as she stared into her sister's eyes. She could feel the intensity building to incredible heights and she knew she would climax soon. She wanted to speak to Mandi, but she couldn't - she was concentrating too hard on getting everything just right. She pushed down harder, increasing the speed of her grinds. She stared at Mandi, watching her face grow more and more intense. Suddenly, she felt everything in her rise up and build to the most incredible peak she'd ever experienced. "Oh Mandi!" she grunted and squeezed her eyes shut as she tensed and shuddered against her sister. "MMMMMMMFFFFF!!" she squealed as she exploded in climax. Mandi was already on edge due to Kaylee's intense grinding, and when Kaylee cried out her name and tensed, it hit Mandi like a ton of bricks. She shut her own eyes and gripped her sister's arms as tight as she could as she climaxed. "Oh... Ka... OH GOD... UNNNNNGHHHHHH!" she grunted as she shuddered beneath her sister. Both girls were lost in a daze of ecstasy as their hearing faded, then their vision. All they could feel was each other, joined together in a state of pure bliss. After what seemed like ages, Kaylee's hearing slowly came back as she heard a distant but familiar voice. "...Kaylee? ...Kaylee, get up!" Kaylee slowly returned to consciousness. "Huh...?" she said, groggily. "Get up, you're crushing me! It's hard to breathe..." Mandi was saying. "Oh God... sorry," Kaylee said. She must have collapsed on top of Mandi and passed out. She slowly rose up onto her elbows, looking down at her sister. "Uh! Thank you!" Mandi gasped, taking in deep breaths. Kaylee looked down at Mandi. "How long was I out?" "I dunno... I passed out too," Mandi said, and they both giggled. "All I know is when I woke up, you were crushing me." "Sorry about that," Kaylee said. "It's okay," Mandi said. "I guess I blacked out. But up until that point, it was the most incredible thing I've ever felt in my life," Kaylee said, sincerely. Mandi blushed lightly. "I know," she said. "Me too." Kaylee looked down at her sister lovingly. "My God, you're beautiful," she said. Mandi's blush got deeper. "Thanks," she said. "So are you." Kaylee leaned down and kissed her sister gently on the lips. A wonderful warmth passed over her as Mandi returned the kiss. They spent several minutes kissing tenderly, feeling the softness of their lips against each other and enjoying every second of it. Eventually, Kaylee broke away and looked down again at Mandi. "I love you so much," she said. Mandi smiled. "I love you too." "I don't want to leave this room," Kaylee said. "Let's just sleep here tonight, you and me." Mandi smiled. "Okay. Can we cuddle?" Kaylee smiled. "I can't think of anything I'd rather do more," she said. With that, Kaylee turned off the lamp, pulled the covers over them, and snuggled up tight to her sister, kissing her softly. Within minutes, both girls were in a deep sleep. ************************************************** Kaylee awoke just before dawn. It was the most restful sleep she'd had in weeks. She was a bit disappointed as she remembered she had to get up and go to school today. At least it was Friday, she thought. She sat up and looked down at her beautiful sleeping sister, with whom she'd been cuddling all night. She hated to disturb her sleep, but it was nearly time for them to get up anyway. Kaylee leaned down and gently rubbed her sister's shoulder. "Hey sleepyhead," she said. As Mandi began to stir, Kaylee leaned down and gently kissed her sister's lips. God, it felt good to do that, she thought to herself. "Wake up, sweetie. It's time to get up," she said softly. "Mmmm..." Mandi groaned as she slowly opened her eyes. "Did you sleep well?" Kaylee asked. Mandi nodded, bleary-eyed. "I just had the most amazing dream..." she said. "Really?" Kaylee said. "What was it about?" "I dreamt..." Mandi said, thinking, "...that I became your girlfriend... and we were, like, going out together," she said. Kaylee's expression changed, like she'd just heard the sweetest thing in the world. "Oh my God," she said. "That's so beautiful!" Mandi smiled. "Really?" Kaylee nodded, biting her lip. "So will you?" "What?" Mandi asked. "Be my girlfriend?" Mandi was now wide awake. She sat up in bed. "Really?" she asked. Kaylee nodded sincerely. Mandi hadn't considered this. It sounded odd - being her sister's girlfriend - but considering everything they'd been through last night, maybe it wasn't so weird after all. She thought about it, and it did sound really romantic. She'd never 'gone out' with anyone before, and it scared her and excited her at the same time. Could she do this? Commit to being in a relationship? With her own sister?! She looked into Kaylee's eyes. Suddenly her fear vanished. "Okay," she said, smiling. "Oh Mandi!" Kaylee cried, throwing her arms around her sister and hugging her tight. "I love you so much!" "I love you too, Kaylee!" Mandi said. Kaylee then pulled back and looked at her sister. "But wait," she said. "We have to make it official. It's not official until we kiss. That's how it works. So since I'm the one who proposed the question, you have to be the one to confirm it by kissing me." "I do?" Mandi asked. "Uh-huh," Kaylee said, nodding. The girls looked at each other. "Okay," Mandi said. She took a deep breath. She looked at Kaylee. "Ready?" she said. Kaylee nodded, sitting patiently, her hands in her lap. She waited another second, and then watched Mandi move towards her slowly. As Mandi got closer, she saw her close her eyes. Kaylee closed her own eyes and took a deep breath. By the time she was finished exhaling, Mandi's soft lips were on hers. It was a tender kiss, soft, and slightly moist. Mandi held her lips against Kaylee's for a long time. No heavy movement or making out, just a soft, lingering kiss that left Kaylee growing warmer and wetter by the second. If their first couple kisses had been intense, passionate, and erotic, this was by far the most romantic. It was soft, simple, and deeply meaningful. The longer Mandi held the kiss, and the more she pressed her mouth against Kaylee's, the more Kaylee could tell she really meant it. Then, just before pulling away, Mandi opened her lips and slid them across Kaylee's, closing them back to a gentle pucker, and pulled away. Kaylee slowly opened her eyes and looked at Mandi. She seemed to be glowing. "Wow," Kaylee said, nearly breathless. Mandi smiled coyly, blushing slightly. She licked her bottom lip, pulling it into her mouth and biting it. "I can't believe it," Kaylee said. "I have the sexiest girlfriend in the world." Mandi blushed harder, smiling shyly. Just then, the girls heard their parents walking down the hallway and into the kitchen. "Crap!" Kaylee gasped. "Mom and dad are up! Quick, we've gotta sneak back to our rooms!" The girls quickly made the bed and, once they were sure their parents were both in the kitchen, snuck out of the guest room and crept down the hall to their own bedrooms. All day, both girls were filled with a glowing warmth they never knew before. Their declaration of love and commitment to each other left them on a wonderful high and they felt closer to each other and more connected than ever. They could barely focus on their classes. Even when they got home, they couldn't stop glancing at each other and smiling, blushing, and getting tingles all over. Over dinner, they couldn't help but play footsie with each other under the table. Evening couldn't come soon enough. By the time it did, both girls were giddy with excitement. Each girl separately decided to put on her best pair of panties, hoping to turn her new girlfriend on just a little bit more. They lay in their own beds, waiting terribly impatiently for their parents to go to bed. When Kaylee was sure she heard her parents' door close for the night, she quietly crept out of her room. As she was tip-toeing down the hall, she accidentally bumped into Mandi in the darkness. Both girls gasped sharply, having caught each other by surprise. "Omigod, Mandi!" "Kaylee! You scared me!" they whispered. "I didn't think you'd come out so early!" "I know, I just... couldn't wait any longer!" "Me either!" They broke into giggles. "Shhhhh! Mom and dad will hear!" "Sorry!" They crept down the hallway to the other end of the house and into the guest room. They shut the door and turned on the bedside lamp. Kaylee immediately wheeled around and looked Mandi in the eye. "Omigod, you're so beautiful," she said and threw her arms around her, pressing her lips tight to her sister's mouth. For good measure, she threw her leg up around Mandi's hip, crushing her body tightly to her own. The girls kissed, hands roaming, lips and tongues exploring, bodies sliding and grinding. During occasional breaks in the mingling of their mouths together, Mandi tried to get a few words out. "Shouldn't... mmmh... we - mmmfh... go to - mmh - the bed? Mmfh.." "Mmm-Hmmmffh..." Kaylee grunted, her mouth still crushed to Mandi's. And with that, she began pulling Mandi back toward the bed. When they reached it, they fell back on it, momentarily breaking their kiss. But Kaylee quickly remedied that, lunging for her sister's mouth as soon as she was able. The girls kissed and groped, writhing around on the bed. Finally, Mandi broke away. "Kaylee, wait. I wanted to show you something," she said. Kaylee groaned as Mandi got to her knees. Mandi looked down at Kaylee, trying to put on her best naughty face. "I wore my sexiest pair of panties for you tonight," she said. Kaylee just stared, gasping for air. Mandi grabbed the bottom of her oversized t-shirt and pulled it over her head. She was now naked except for a small pair of frilly pink panties. Kaylee's eyes dropped to them, taking them in. "Do you like them?" Mandi asked. "Uh-huh," Kaylee said. "But I've never wanted such sexy panties to come off so quickly!" Mandi smiled, biting her lip. She reached down and hooked her thumbs in the waistband. "Wait," Kaylee said. "Turn around." Mandi pulled her thumbs out and turned around so her back was to Kaylee. Kaylee drank in the sight of her sister's round little butt cheeks, tracing her sister's pantyline with her eyes as it curved over those wonderful cheeks and disappeared down and between them. "Mmmmm," she moaned. "I'm not so sure I want them off anymore," she said. Mandi half-giggled and turned back around to face her sister. "Well?" she said. "Never mind," Kaylee said, grinning. "Get them off. Fast." Mandi began to push her panties down her legs as Kaylee sat up and pulled her own shirt off. Kaylee paused momentarily. "I actually wore my best pair tonight for you too," she said. "But oh well. I'm too hot right now," she said, pulling them down and off. Kaylee settled back on the bed and spread her legs. "Come here," she said to Mandi. "I want you on top of me." Mandi smiled and got down on all fours, straddling one of Kaylee's legs. "No, not like that," Kaylee said. "Like I did to you last night." "Oh," Mandi said, moving her knee inside Kaylee's spread legs. "But I don't really know how..." "Just trust me," Kaylee said. "Just like that. Now get yourself right over my hips... there... like that." Kaylee reached up and began to guide her sister's hips. "Okay. Open your legs a little... now lower your hips down." Kaylee guided Mandi's hips as she began to lower them. When their hips came in contact, both girls groaned. Kaylee continued her instructions. "Now move your hips up just a little... UUHHHH! Do you feel me?" Mandi's mouth was open and her eyes were wide. She nodded. "It's so hot!" Kaylee nodded, smiling. "That's how you feel on me too." Mandi gasped again. "Omigod... this is... this is... Wow!" Kaylee grinned. "Just wait till you start moving." "M-moving?" Mandi eeked out. "Here," Kaylee said, moving her hands up and around to Mandi's bottom. She grabbed both cheeks and pushed down into her. "UUUUUUUNNNnnnnffffffhhh!!" the girls grunted simultaneously. Kaylee looked up and met Mandi's eyes. "Do that over and over," she said. It was nearly a command. Mandi gasped. She swallowed dryly, then began to do as her sister instructed, pushing her hips down and back over and over. "UH!" she gasped, her mouth hanging open as she pumped. "Yes..." Kaylee hissed. "GOD yes..." Fireworks went off in Kaylee's head as she grabbed her sister's butt over and over, squeezing handfuls of it and aiding in Mandi's thrusts. It was the hottest thing Kaylee had done to that point and it was bringing her close to the edge faster than she thought. "Oh God, Mandi..." she gasped. "Faster... yes... Faster!" Mandi pushed and thrust with all her might, looking down into her sister's amazingly intense face and feeling her hands on her, pushing herself into her. But all of this was secondary to the incredible heat she felt mashed between her legs, and the friction generating an incredible sensation welling up quickly within her. She couldn't believe anything could feel so amazing. This was the hottest, most erotic thing imaginable, looking into her sister's face as she was mashing herself against her hot, wet sex. She could feel Kaylee squeezing her butt, shoving it down, pushing her even harder against Kaylee. She winced as the friction grew more intense, and suddenly she found herself pushing even harder, biting her lip tightly. Kaylee was locked in a near trance as she stared intensely into Mandi's eyes, bucking her hips up into Mandi, meeting her thrusts and doubly increasing the friction on their swollen, wet mounds. Lubrication had seeped and spread across both of their crotches, causing them to slide quickly over and across each other. Kaylee could acutely feel each of her little folds rub tightly over and across Mandi's, and quickly developed a system to angle her hips so that her little pleasure button was in contact with Mandi's slick folds. Once this was in place, her face scrunched up and she thrust herself harder and tighter up against Mandi, while allowing Mandi to work her hips down against her. She did this for about ten or eleven thrusts, feeling the intensity rapidly increase. On the next thrust, she felt everything erupt. She threw her head back and squealed, grabbing Mandi's butt, pulling it hard and tight against her as she felt Mandi continue to pump in tight little jerks against her. The feeling was unlike anything she'd ever experienced and she thrust her hips up tight against Mandi, lifting her off the bed slightly. "AAAAAAAaaaaeeeeeEEEEEEE!!" she screamed. Mandi was amazed at her sister's movements and expressions. She watched her sister writhe in climax, continuing to pump her hips into her. She felt her heart pound incredibly hard as she watched her sister and suddenly, on the next thrust, she felt everything rise. She tensed, her eyes rolled back in her head, and she shuddered tightly against her sister, feeling Kaylee's thin fingers grip her bottom tightly. The girls squealed and shuddered against each other, bucking and pumping unevenly for another minute or so as they rode out their incredibly intense orgasms. Soon, they both blacked out and collapsed, breathing heavily in a desperate attempt to catch their breaths. Mandi slowly came to, panting and sweaty, feeling her sister's hot body heaving beneath her. She raised her upper body, placing her hands on either side of Kaylee and looked down at her. She was still out, eyes closed, but breathing heavily. Through her haze, Mandi thought she looked beautiful. She could barely believe what had just happened. It was by far the most intense experience of her life. She hoped Kaylee felt the same way. Slowly, she leaned down and kissed her sister's soft lips. Kaylee came to, awoken by a wonderfully soft kiss. She looked up at the most beautiful face she'd ever seen. "Hey beautiful," she said softly. Mandi grinned. "Hey." "That was pretty intense, huh?" Kaylee asked. "GOD yeah," Mandi said, rolling her eyes for emphasis. "I love you so much," Kaylee said. Mandi grinned widely. "I love you too." Kaylee leaned up and took Mandi's face in her hands, pressing her lips firmly to her sister's. She pulled Mandi's face down with her and rested her head on the pillow as they held their kiss. It was long, soft, and sexy. It was a kiss of pure love and devotion. After nearly a full minute, the girls finally broke their kiss. Mandi kept her forehead pressed to Kaylee's as they looked into each other's eyes, smiling. Kaylee had been thinking about something for a while, wondering when or if the right time to tell her sister would arrive. She figured now would be as good a time as any. She did want to say it, as she felt it would improve their sex lives considerably. At least she hoped it would. Besides, she wanted to be open and honest with Mandi. She bit her lip in thought. "Mandi..." she said softly, "...I have a confession to make." Mandi lifted her head up, looking at her. "Really?" she said, curious. "Yeah..." Kaylee said, the slightest hint of embarrassment in her voice. "I... really like your butt." Mandi furrowed her eyebrows and smiled. "You do?" "Yeah," Kaylee said, biting her lip. "Like... a lot." Now it was Mandi's turn to blush. "Like... what do you mean 'a lot'?" "Like... it's almost all I can think about," Kaylee said. "It's SO incredibly sexy. I just can't get enough of staring at it, touching it, grabbing it, squeezing it... GOD! It's getting me hot all over again." Mandi smiled, still blushing. "Really? Wow, I had no idea." "Oh yeah," Kaylee said. "Once, a few weeks ago... I saw you going to the bathroom to take a shower... and you didn't have any panties on. I saw it and... Oh God. I went to my room and immediately got myself off, thinking about it." Mandi smiled wider. "Really? Wow. That's... I had no idea. I mean... I did notice you grabbing it a lot just now, but... wow." "Oh God... yeah," Kaylee said. "I actually want to grab it some more. Can I?" "Um... okay," Mandi said. "Here... sit up," Kaylee said. Mandi did as she was told and got up, straddling her sister's hips. "Oh yeah, just like that," Kaylee said. "Now scoot down just a little, so your pussy's right over my pussy." Mandi grinned as she scooted down. "That's better than 'kitty,'" she said. Kaylee grinned. "Uhhhh, yeah. Good," Kaylee said as her sister got into position. Mandi giggled a little again. "Everything's still so wet down there." "I know," Kaylee said lustfully. "Isn't it awesome?" Mandi nodded, smiling. Kaylee put her hands on her sister's waist. "Okay," she said, sliding her hands down to Mandi's hips. "Now, push your hips back and forth on me, and see if you can feel anything." Mandi began to slide her hips and immediately her eyes flew open and her jaw dropped down. Kaylee squeezed her eyes shut, already knowing this was going to be better than she thought. "Wow!" Mandi gasped. "Yeah..." Kaylee said. "Keep doing that." Mandi had no problem following these instructions as she slid her hips back and forth across Kaylee's, her wet sex sliding across Kaylee's. The pressure was amazing since Mandi was sitting up and had her whole weight down against her sister. "Good..." Kaylee said, "just like that." She slid her hands around Mandi's hips, down to her smooth bottom. Kaylee's jaw dropped as she felt the muscles in Mandi's butt flex and clench with each thrust forward. THIS was what she was after, and it was better than she could have imagined. The feeling of her sister's smooth, tight butt clenching and unclenching into her palms was just as hot as the feeling of stimulation on her sex. She had just experienced the most powerful orgasm of her life thus far, but she felt she could quickly build to another one with no problem. "Oh God Mandi... Yes..." Kaylee panted, staring up at her sister. "Go faster." Mandi, staring down at Kaylee, felt a little self-conscious in this position. She didn't quite know what she was doing, and she felt vulnerable with Kaylee staring at her whole body like this, but it did feel incredibly good and she wanted to make her sister happy. So she started moving her hips faster, almost jerking them back and forth. "UNH!" Kaylee groaned through gritted teeth. "OH GOD!" She grabbed hold of Mandi's tightly flexing cheeks and began to pull them forward with each thrust, increasing the friction as she slid forward. "Oh Mandi! UNH! Keep going! I'm so close!" These words did something to Mandi. Somehow, knowing that her sister was close to release made her want to work harder. She began to pump her hips as hard and quick as she could against Kaylee, hoping to bring her to an incredible orgasm. Kaylee's jaw dropped at this new surge of energy from her sister. She couldn't believe how quickly Mandi was moving her hips. It was the hottest thing she'd ever seen. She could see Mandi's little boobs bouncing and jiggling up and down as she jerked. She looked back up at Mandi's face and it was red, but she didn't care. She went right back to staring at those tightly jiggling little boobs and felt herself rise. She knew she couldn't hold out much longer. "UNNNGH! Yes Mandi!" she cried. "Faster! FASTER!" Her boobs jiggled harder. Her butt flexed tighter. Everything slid against her hot and slick. Her mind was a jumble of boobs, butt, and slickness. Hard. Fast. Her head slowly leaned back and her eyes rolled back as she tensed and grabbed Mandi's butt as hard and tight as she could, feeling the muscles fight back against her hands. "UUUUNNNNNNGGGGRRRRRRRRRRRRHHHHHHHHHHHH!!!" Kaylee grunted as she thrust her hips up hard into her sister. Mandi was blown away by her sister's actions and expressions. It was the hottest thing she'd ever seen, and as soon as Kaylee gripped her bottom hard, she went over the edge herself. She rode out her climax as Kaylee lifted her up slightly off the bed, and suddenly she felt an incredibly hot burst of pressure against her sex. She continued to jerk herself around, listening to Kaylee's grunt and letting it fuel her orgasm. She was surprised to feel a whole bunch of liquid between them and began sliding faster, smearing it all over their crotches. Mandi kept jerking, riding everything out until she felt Kaylee lower her back to the bed. Kaylee at some point had lost consciousness. If she thought the previous orgasm was amazing, nothing could have prepared her for this one. It almost immediately took her to heaven, and then Mandi kept sliding and grinding against her! The sensations were too much, and she blacked out. When she came to, she heard Mandi softly calling her name. "Kaylee?" Kaylee opened her eyes, staring up at her beautiful twin sister. "Are you okay?" Mandi asked. Kaylee licked her dry lips. Then she smiled faintly. She nodded, still unable to speak. "You looked like you passed out," Mandi said. Kaylee nodded again. "Was that good?" Mandi asked. "Say something." Kaylee opened her mouth slowly. "Oh. My. God." Mandi smiled. "So it was good then?" Kaylee closed her eyes and nodded slowly. Mandi beamed, pleased that she could make her sister feel this way. Eventually Kaylee opened her eyes again. "Do you know what you did?" Mandi asked. "What?" Kaylee said, vaguely curious. "You, um... kind of got us all wet," Mandi said. "Huh?" Kaylee said, slowly coming out of her daze. "Yeah... it's, like, everywhere," Mandi said. "I don't know exactly what happened." Kaylee began to sit up. Mandi slowly slid off of her sister and onto the bed, revealing the extent of the wetness. "Oh my God," Kaylee said, seeing the mess. "That was me?" "Yeah," Mandi said. "I felt it... right when you... you know." Kaylee blinked, her eyes widening. Her crotch, stomach, and thighs were all covered in a thin liquid, as well as a good portion of the sheets. "At first I thought it was pee," Mandi said. "But it doesn't feel like pee. It's slimy, see?" she said, rubbing it between her fingrs. Kaylee rubbed some between her fingers as well. "Weird," she said. "Yeah," Mandi said. "It felt really good when it was smearing around between us," she said, blushing a little. Kaylee giggled. "Yeah, I bet. I wonder why that happened." "I dunno," Mandi said. "Maybe because you felt so good." "Maybe," Kaylee said. "But if that's what it takes to feel that way, I hope I do that every time!" Both girls giggled at this. Soon, Mandi crawled up beside her sister and they cuddled, pulling the covers up over themselves. Kaylee looked into her sister's eyes, their faces inches apart. "I love you so much," Kaylee said. "I love you too," Mandi said. The girls kissed, and then snuggled together to go to sleep. *********************************** The next day, the girls were positively glowing. They had to scramble to get ready before their parents got up, but they managed to do just that and look presentable. The hardest part was trying to conceal their newfound affection for each other. After breakfast, as Mandi was in the bathroom, she couldn't help thinking about what Kaylee had confessed to her the other night. It made her feel so good to be appreciated by her sister. After she finished her business on the toilet, she pulled her panties up and then looked at herself in the mirror. She turned around and began to check out her own butt. It was rather round and shapely, she thought. She quickly ran over to her dresser and grabbed her phone. Standing back in front of the mirror, she turned the camera on on her phone and positioned it toward the mirror. Reflected in the mirror was her arched back, curving down to her round, panty-covered butt. She snapped a picture. Then she pulled up her tight black spandex pants, made sure her butt still looked good in them, and then texted the photo to her sister. When Mandi made her way back down to the kitchen, she bit her lip as she made eye contact with her sister. Kaylee gave her a devastatingly sultry look, and Mandi knew she'd seen the text. She tried to hide her smile, but didn't do a very good job. The girls spent the rest of the day desperately trying to act normal around their parents as they tried to conceal their burning desire for each other. They kept giving each other knowing looks and glances, biting their lips, smiling mischievously, and licking their lips. It drove them both wild. The whole day, Mandi noticed that Kaylee kept looking down at her phone and then looking back up at her with a sexy glare. She figured Kaylee kept looking at the photo she texted her that morning and felt herself swell with pride. What Mandi didn't know was that Kaylee had, throughout the day, been snapping her own photos of Mandi's butt when she wasn't looking and creating a whole folder dedicated to them, scrolling through them when she felt the urge to get aroused, and exponentially increasing her arousal in the process. Kaylee simply couldn't get over how sexy her sister's butt was. It made her unbelievably hot. Especially considering the tight spandex pants Mandi was wearing today. Kaylee thanked God Mandi decided to wear them. They were so tight and snug, they perfectly showed off the amazing shape and curve of her sister's butt, and it made Kaylee yearn with a burning urge to reach out and grab it, squeezing handfuls over and over. But she restrained herself. Mandi had a hunch Kaylee was enjoying the pants she had on, and she tried to do her best to give Kaylee a nice view of her butt whenever she could. She got excited knowing that her sister was watching her and checking her out, and she hoped Kaylee enjoyed the view. She couldn't wait until they could be alone again in the spare bedroom later that night. The day went on like this back and forth, with Mandi trying to show off her butt to her sister and Kaylee snapping candid photos of her sister's sexy butt, getting herself worked up. Dinner time was the worst, because their parents were right there, and Mandi was sitting on Kaylee's favorite part, hiding it from view. The day couldn't end soon enough. At around 10:00pm, the girls retreated to their separate rooms, waiting for their parents to go to bed. Mandi lay awake on her bed, thinking about Kaylee and hoping she was pleased with what Mandi had worn that day and how she had displayed herself. She couldn't wait to hear what Kaylee thought - especially of the text she sent her that morning - and how she felt. She couldn't wait to feel her sister's arms around her, holding her close, the feeling of her lips against her own, of Kaylee's tongue in her mouth. But most of all, she couldn't wait to feel her sister's hot, wet sex against her own, grinding around and sliding back and forth. She desperately hoped Kaylee wanted to do that again. Kaylee lay on her bed, scrolling through the pictures on her phone that she'd taken of her sister's butt. She had a pillow between her legs and was squeezing it with her thighs as she scrolled through the images. She particularly liked the ones of her sister standing straight up, turned slightly to the side. She could see the perfect curve of her sister's butt and how it rounded deeply down and inward to her thighs. Kaylee said a silent prayer thanking her sister for wearing those pants, and squeezed the pillow tighter against her. She was working herself up quite heatedly, but she was careful not to get too close to the peak. That, she wanted specifically to save for Mandi. Time passed rather quickly for Kaylee, and before she knew it, she heard her parents head to their room and turn in for the night. Quickly, she put her phone down and ran to her door. She put her ear against it, and when she heard her parents' bedroom door close, she opened hers and tiptoed out into the hall. Once in the hall, she was surprised to see Mandi's door open and her sister creep out into the hall. They startled each other and their hands flew to their mouths to keep from making a noise. They giggled silently with each other and held hands as they quickly walked down the hall to the spare bedroom. Once inside, Kaylee closed the door and Mandi flicked on the light. Almost instantaneously, they rushed toward each other, arms wrapping tightly around each other, and mouths meeting in a hot and hungry kiss. Kaylee's hands immediately slid down to her sister's bottom and sighed as she felt Mandi's nylon pants that she was still wearing. Her hands slid down over her sister's cheeks and cupped them at the base, squeezing them tight in her palms, crushing her sister's hips against her. She squeezed and kneaded Mandi's soft round flesh, moaning into her mouth. Mandi kissed her sister harder, pushing her tongue deeper into her mouth and sliding her lips across Kaylee's cheeks. The girls kissed hotly, grinding against each other until Kaylee broke away, gasping for air. "Oh my God!" she panted. "I can't believe how hot you're making me!" Mandi smiled. "You like these pants I'm wearing?" she asked. "GOD yes!" Kaylee sighed, squeezing her sister's butt tightly. Mandi beamed. "Did you like the picture I sent you this morning?" "Omigod, I LOVED it!" Kaylee gasped. "I loved it so much, in fact, that I took, like, thirty more pictures of your butt today when you weren't looking!" Mandi's mouth fell open in mock horror, still smiling. "You dirty little perv!" she said. Kaylee grinned. "I'm not the one who texted my own sister a picture of my butt in my skimpy little panties," she said, squeezing her sister's butt again. Mandi bit her lip, blushing slightly. "Does that make me a perv too?" "Yes," Kaylee said, grinding her crotch against Mandi's. "A dirty, adorable little perv who I can't wait to get into bed with." She grinned widely. Mandi grinned again, looking down and blushing. "Now take off these pants and hop into bed. I've been waiting all day for this and I can't wait another second," Kaylee said, giving her sister's butt one last squeeze before pulling back so she could take off her clothes. Kaylee pulled off her clothes in a flash and hopped on the bed, completely naked. She turned on her side and watched her sister take off the rest of her clothes. It took Mandi a little longer to pull off the tight nylon pants, and Kaylee thoroughly enjoyed watching her do it. Once Mandi was naked, she jumped onto the bed next to Kaylee, grinning. After a second of admiring each other's bodies, Mandi asked, "So, um... how do you want to do it?" Kaylee grinned widely. "I've been thinking a lot about this," she said, with a mischievous twinkle in her eye. "And I want you to sit..." she paused, rolling onto her back, "...right here," she said, placing her hands above her crotch, mimicking like she was holding Mandi's hips. Mandi bit her lip, smiling. She was excited to be rubbing 'minkies' again with her sister, but was expecting something a little different. "But we already did that," she said. Kaylee grinned. "We did that with you facing me," she said. "I want you to turn the other way so I can watch your butt while we do it." Mandi's heart skipped a beat. That was so... wild! She got a little thrill at the idea of her sister watching her butt work back and forth on top of her. She knew how much Kaylee enjoyed the shape of her butt, and she was suddenly filled with a strong desire to make sure Kaylee got the show of a lifetime. Her face beamed. "Okay," she said softly. She then got up, turned around, and swung her leg over her sister, straddling her hips with her back to her. "Like this?" she asked, turning back to look at Kaylee. "Uh-huh," Kaylee said, eyes wide and glued to Mandi's butt. Mandi then leaned forward on her arms and began to lower her hips down slowly, until she could feel the heat radiating from her sister's crotch against her own. Then she looked back at her sister again. "Like this?" she said again. Again, Kaylee's eyes were glued to Mandi's butt. Mandi doubted she ever moved them. "Uh-huuunh..." Kaylee breathed. Mandi then lowered her hips the rest of the way and felt her sex come into contact with her sister's swollen, puffy mound. "Uuunnnnnh," both girls moaned simultaneously. Mandi then began to straighten herself up, putting her full weight down against her sister's hips and crotch. "Oooooooh Goddd!" Kaylee groaned. Mandi, then sitting straight up on her sister's hips, turned her head back around. "Like this?" she asked. As expected, Kaylee's eyes were still on her butt. "Uh-huh! God, that's perfect!" she gasped. Kaylee's hands then moved up to her sister's hips and gave them a squeeze. "Please, Mandi. I need to feel you moving. I need it so bad!" Mandi smiled. Then she pushed her hips forward once, sliding against her sister's sex. "Ohmigod! Uunnnh!" Kaylee grunted, throwing her head back. Mandi grinned, loving both how it felt and her sister's reaction. She then began to pump her hips back and forth at a moderate and steady rhythm, her mouth falling open as she did so, utterly amazed at the sensation. "Unnh! Omigod, Mandi! Oh! OmiGOD!" Kaylee grunted, keeping her hands on her sister's hips. "Uh! Omigod, yes! Oh! Oh GOD yes!" Mandi grinned wider, closing her eyes and reveling in the amazing sensations. She continued to thrust her hips, paying attention to how she flexed her butt. "Mandi!" Kaylee gasped. "Oh God! Your butt! It's so... oh God! So hot! Keep going, baby, please! Keep going!" Mandi got a warm tingle upon hearing her sister call her 'baby.' It made her feel like they were really in a relationship... really going out... real girlfriends. She wanted more than anything to please her sister. She began to pump her hips faster. "OH! Mandi, yes! Please God, yes! Do it faster! Oh God, it's so amazing! Mandi, it's so beautiful! Omigod!" Kaylee was utterly transfixed by the sight in front of her. Her sister's beautiful, round, smooth butt was pressed firmly down against her crotch and flexing tightly back and forth, over and over again. She particularly loved to watch it flex tight, right over her crotch. She could see her sister's muscles clench into tight little globes, and it got her more excited than she thought possible. "Please, Mandi, please! Oh God! Don't stop!" Kaylee gasped, eyes glued to the tight, flexing cheeks in front of her. "God, it's so hot! Omigod!" she panted. Mandi was loving the words coming from her sister, and particularly the urgency with which she spoke them. It was obvious that Kaylee was having one of the most intense experiences of her life, and Mandi was overjoyed to be giving it to her. She began to squeeze her cheeks tighter as she pumped, her arousal rising at the thought of giving her sister an amazing show, and making Kaylee even hotter in return. "OH! FFF-... Mandi! Oh YES! Uuunnnnrggh!" Kaylee gasped, then grunted forcefully. "Oh God! Your butt! Please! Yes! Tighter! Faster! Harder! UNH!" Mandi was practically glowing hearing these words. They made her feel so good, so hot, so... sexy. She worked harder against her sister, pushing her hips down and thrusting her sex hard and tight against Kaylee's. "MANDI! Oh! Oh God, yes! I'm... I'm gonna... Oh God! Don't stop!" Kaylee panted. Mandi worked her hips hard and fast, jerking her butt tightly against her sister's crotch. Her mouth dropped at how good it felt. She was close. So close. "MAAND- UNN- UUUUUUUUUUUNNNNNRRRGHHHHHH!" Mandi felt her sister's hands grip her hips tightly and pull them down hard against her. The next thing she knew, Kaylee was thrusting up hard into her and shuddering beneath her. Mandi gasped audibly at the added pressure and felt herself rising to the peak. Kaylee's vibrating, shuddering hips pushed her over the edge and she squealed, eyes closed, her mouth falling open gasping deeply for oxygen. It was then that she felt a torrent of liquid jetting forcefully against her sex, hitting a sensitive spot. She redoubled, jaw falling open wider as she experienced an even higher level of pleasure than she thought possible. In the distance, she heard Kaylee grunt loud and hard as she continued to shudder beneath her. The liquid stopped and Mandi was still in the middle of her orgasm, trying to keep herself upright, when the liquid came back, hitting the same sensitive spot. Mandi was utterly dumbfounded, reveling in the most extraordinary bliss of her young life as the liquid shot three more forceful jets against her sensitive sex, one even parting her folds and sliding up into her. It was the longest and most intense orgasm of either girl's young life, and when it was over, Mandi was leaning forward limply, resting on her arms for support, and Kaylee lay with her head back, staring up at the ceiling, her hands still limply holding her sister's hips, both girls gasping desperately for breath. They lay like this for several minutes, simply catching their breaths and basking in the wonderful afterglow. "Mandi..." Kaylee finally managed. "That was... unbelievable. I've never felt so amazing in my entire life." Mandi smiled. "Me either," she said. "But, um... what was that liquid stuff?" Kaylee blushed bright red, still staring at the ceiling. She knew it had happened, and realized of course Mandi must've felt it. "I... I don't know," she said truthfully. "All I know is it came out of me at the very peak... and it was the best feeling I've ever had." Mandi paused, trying to formulate a response. "It... it hit me right in my most sensitive spot, right when I was... at the peak too," she said. "Really?" Kaylee gasped. "Oh my God, I'm so sorry!" "No, no, no..." Mandi said as she straightened herself up. She sat herself up and limply attempted to turn herself around, very aware of the copious amounts of liquid between them. Kaylee grunted as she turned, and Mandi faced her sister, and slowly laid her body down on top of Kaylee's. They looked into each other's eyes. "It was..." Mandi began, "the most amazing thing I've ever felt." "Really?" Kaylee said, breaking into a grin. "Mm-hmm," Mandi said, nodding and grinning. Kaylee stared up at her sister, her eyes sparkling, as her hands crept up Mandi's sides and came to rest on her bottom. "Some..." Mandi started, blushing a little. "Some of it even went up inside me," she said. Kaylee's mouth dropped in surprise. "Really?" she said. Mandi nodded, blushing as she smiled. "I don't know if I should apologize or get excited again," Kaylee said cautiously. Mandi bit her lip. "Well..." she said, blushing brighter. "You definitely don't need to apologize..." Kaylee's mouth fell open as she realized her sister's implications. "Omigod," she said hungrily and leaned up to kiss her sister, squeezing Mandi's bottom as she did so. Mandi moaned into the kiss, sliding her tongue deep into her sister's mouth. After locking lips and sliding their tongues around each other's mouths, Kaylee pulled back to gasp for air. "God, you're amazing," she panted. Mandi grinned. "So are you. I hope we never stop doing this." "I can't imagine why we ever would," Kaylee grinned, squeezing her sister's butt again. ******
