Date: Mon, 1 Jul 2019 21:59:47 -0700 From: Jojo Starr Subject: Butt Discoveries - Chapter 5 BUTT DISCOVERIES Chapter 5 All day at school, Katie was excited. She'd picked up a whole bunch of other things at the candy shop that she wanted to try with Lizzie, and she felt Lizzie hadn't really considered her things yet. Yesterday was just so overshadowed by the giant jawbreaker that Katie hadn't had a chance to try any of her candies yet. Katie wasn't complaining too much though - the jawbreaker had been pretty awesome. Even as she thought about it, sitting at her desk in class, she rocked back, pressing her butthole against her seat, and ground down hard, trying to approximate, as much as possible, the stimulation she felt yesterday on her butthole right in the middle of class. When they got home, Lizzie wasted no time in getting down to business. "So what did you have in mind for today?" she asked with a twinkle in her eye. Katie grinned. "Come on, I'll show you." The girls ran to their room and Katie reached under the bed to pull out her bag of candies. She reached into the bag and pulled out two hearts on a stick, wrapped in red foil. Since Valentine's Day was approaching, the store was full of heart candies. "Let's start with these," she said, holding them up. "What are they?" Lizzie asked, thinking that those looked a little boring, compared to what they'd tried yesterday. "They're chocolate hearts on a stick," Katie said. She seemed to notice Lizzie's slight disappointment. "Come on, please? It's just to start with," she said. "I promise it'll be fun." Lizzie took one and examined it. At its widest, it looked about as wide as the jawbreaker did from yesterday. "Okay," she said. "Can I go first though?" "Sure," Katie said, smiling. Lizzie grinned and pushed her pants and panties down right then and there, kicked them off, then jumped on the bed on all fours. She pushed her butt back toward Katie, spreading her cheeks, then wiggled her hips back and forth and grinned at her sister. "My butt's waiting for you," she said playfully. Katie felt a twinge between her legs. Lizzie was so cute when she did that! She jumped on the bed behind her sister and unwrapped the foil from the chocolate heart. She then casually leaned down toward Lizzie's butt and gave it a little sniff, her sister's aroma exciting her even more. "Don't forget to get me ready first," Lizzie said. "Wouldn't dream of it," Katie said. "That's like my favorite part!" With that, Katie bent down and extended her tongue, placing it right against her sister's smelly, pink pucker. She heard Lizzie sigh loudly as she began licking at her sister's sticky, slightly damp butthole. Her sister's aroma filled her nostrils as she licked, and Katie reveled in the sensations of her sister's bumpy, wrinkled flesh sliding across her tongue. When her tongue got dry and sticky, she pulled it back into her mouth to gather more saliva, then went back to licking her sister's anus, spreading her saliva around it. Once or twice, she even wriggled the tip of her tongue into the center of her sister's hole, making her squeal. When Katie was satisfied that Lizzie was good and slick, she sat back on her heels and put the chocolate heart in her mouth, wetting it with her saliva, then pulled it back out. "Ready?" she said. "Mmmm, yesss," Lizzie moaned, straightening her spine and readying herself. Katie then pressed one of the bumps of the chocolate heart against her sister's slick pucker and pushed. Lizzie's butt sank inward, but the heart didn't seem to be going in. Katie pulled back, then tried again at a different angle. Again, Lizzie's butt sank inward, but the chocolate heart didn't go inside. "It's not really going in," Katie said. "Probably because it's a funny shape," Lizzie said. "Just push harder." Katie put the heart back in her mouth to add more saliva to it, then pressed it against Lizzie's pucker again. This time she pushed harder, then angled her elbow upward and pressed down hard against her sister's tight hole. Lizzie's butt caved in deeper than ever, causing her to grunt loudly. "Ungh!" Lizzie grunted. She took a breath and tried to relax. "Keep pushing, but try twisting it around a little," she said. Katie did as she suggested, and began twisting the stick as she pushed, watching the chocolate heart twist against her sister's caving butt. Lizzie gave a sharp gasp, and suddenly her butt opened up, accepting the heart and swallowing it whole. "It worked!" Katie said. "Told you," Lizzie said, huffing a little. "What's it feel like?" Katie asked. "A little different than the lollipops," Lizzie said. "Try pushing it back and forth." Katie began slowly pushing the heart deeper into her sister's butt, then pulled back until the bottom of the heart caused Lizzie's butt to bulge outward before pushing it back in. She did this a few times, letting her sister get used to the sensation. "Ooooh, yeah..." Lizzie moaned. "That feels nice." "Not too weird?" Katie asked. "Nope," Lizzie said. "Just nice. Keep doing it." Katie kept pushing the heart back and forth inside her sister's butt, slowly at first, and then picking up the pace gradually. She wondered if Lizzie was getting close to feeling that tickle between her legs. And then, on the next deep push, she pulled back, and the stick came completely out of Lizzie's butt, with nothing on it. Katie's eyes popped out and her jaw fell as she looked at the empty stick in her hand. "Uhh... Lizzie?" she said. "Yeah? I told you you could keep going," Lizzie said. "Uh..." Katie said, not really knowing how to break it to her. "It broke off." "What?" Lizzie asked, a bit of concern in her voice. Katie held up the stick as Lizzie whipped her head around and looked at the empty stick. "Oh shit," Lizzie said. "It's not gonna get stuck in there, is it?" Katie asked. Lizzie bit her lip. "I hope not!" She seemed genuinely concerned now. She then turned around and tightened her whole body. "What are you doing?" Katie asked. "Trying to push it out!" Lizzie said, grunting. "Is it working?" Katie asked. "Unngh! It's, like, way back there!" Lizzie grunted. "You pushed it in really deep!" "Sorry," Katie said, now really worried for her sister. What was she going to do if she couldn't get it out? Would she have to go to the doctor? Katie shuddered at the thought of having to explain this to their parents. Maybe... maybe if Lizzie just waited long enough, the chocolate would melt and then it would just slowly come out by itself? Katie giggled at the thought of what that would look like in her underwear. It would look like she pooped herself! "Ungh!" Lizzie grunted. She seemed to be getting a little panicked now. "Katie! It's not coming out!" Katie snapped back to reality, once again very concerned for her sister. But what could she do about it? And then she had an idea. "Keep pushing," Katie said, then bent down and sealed her lips around her sister's butthole. She waited until she felt Lizzie push, then she sucked as hard as she could, pulling with her cheeks. "Ungh!" Lizzie grunted. "Omigod, that feels so funny!" When Lizzie pushed again, Katie sucked again, this time really hard. So hard, in fact, that she felt Lizzie's butthole pull back a little bit into her mouth. It was really weird, but she hoped she was helping her. "Unngh!" Lizzie grunted again. "I think it's almost there! Keep doing what you're doing!" Katie felt Lizzie push again, and she sucked hard. Just then, she felt something firm bulging into her mouth, just inside Lizzie's butthole. It was the chocolate! She was doing it! Katie kept sucking as hard as she could. She felt Lizzie push again, and then Katie felt the tip of the chocolate enter her mouth, and then suddenly the entire thing popped inside. "Aaaah! Omigod!" Lizzie gasped, panting heavily. "You did it!" Katie swirled the chocolate around in her mouth, tasting the inside of her sister's butt on it. She was glad she was able to help, although she wouldn't give herself all the credit. 'WE' did it, she wanted to say to her sister, but her mouth was full of chocolate. Lizzie then turned around to face her sister. "Omigod, thank you so much!" she said, throwing her arms around her sister. Katie unexpectedly felt a warm rush as her sister's body pressed against hers. 'This is really nice,' she thought, and put her arms around her Lizzie as well. She sighed as she reveled in the warm embrace. She could stay like this forever. Katie couldn't help but think about those warm, fuzzy feelings she'd been getting lately when she was really close to her sister. She remembered feeling them when they looked at each other really closely, and also when they hugged. And now, she was feeling it again. Especially since Lizzie seemed to be hugging her longer than usual, and a little tighter than usual as well. Katie began to wonder if Lizzie was feeling those same things, or if it was all just in Katie's head. Just then, Lizzie pulled back to look at her, but kept her hands clasped behind Katie's neck. As she looked into Katie's eyes, Katie felt another unexpected rush. The warm fuzziness returned to her, only stronger. Looking into her sister's eyes at such close proximity like this was intoxicating. But she didn't want to read too much into it, in case Lizzie wasn't feeling the same way. "So?" Lizzie said, the corner of her mouth twisting upward. "Does it taste good?" Katie nodded. She felt her heart skip a beat as she thought about asking whether Lizzie wanted to try it too, but couldn't because her mouth was too full. And she really didn't want to ruin the moment by pulling the chocolate out of her mouth. She just wanted to enjoy looking at her sister like this and feeling this warm, funny thing that was making her stomach swirl. Lizzie was looking deep into her eyes. And then, she surprised Katie. "Can I try it?" Katie felt her stomach do a flip. The idea of Lizzie sharing the chocolate with her was terribly thrilling. But how would she do that? Take the chocolate out of her mouth and give it to Lizzie? Wait for Lizzie to open her mouth and push it inside with her lips? Katie couldn't help thinking about the time they shared the lollipop between them, and thought this was the perfect time to try something like that again. Maybe - just maybe - she would even get to feel her sister's lips on hers again. The thought made her heart skip a beat. Katie pushed half of the chocolate heart between her lips, then bit down gently with her teeth, holding it there. It was now Lizzie's move. Would she take it from her? Or would she suck on it right there? Katie was trembling with anticipation. Lizzie held her gaze for a few more seconds, making Katie weak. She couldn't believe how intense this was. Katie was so on edge in that moment. Was Lizzie feeling the same thing she was? Katie stared back into her sister's eyes, searching desperately for any kind of sign that she was feeling a fraction of what Katie felt right then. And then Lizzie parted her lips and slowly leaned forward. Keeping her eyes on Katie's, she slowly wrapped her lips around the half of the heart that protruded from Katie's mouth, and gently sucked on it. She sucked slowly, moving her lips closer and closer to Katie's each time. And then, Lizzie's lips gently brushed Katie's, causing Katie to shudder. Katie couldn't take it anymore. She let go of the chocolate with her teeth and leaned forward, pressing her lips fully to her sister's. She immediately felt Lizzie press back, and a thrilling feeling of warmth and excitement rushed through her. She realized, with a shock, that they were kissing. She and her sister were kissing. On the lips. And Lizzie really seemed to want it! It was all so strange and so delirious and so wrong and also so amazingly, so wonderfully right. This was a place Katie wasn't sure she should ever go with her sister, but here they were, now, doing it. She broke the kiss slightly, opened her lips more, and kissed her sister's mouth more fully, more square - just to make sure. She felt Lizzie wrap her arms around her and grip her lips harder with her own in response. Sparks went off in Katie's head and all over her body. She was kissing her sister! Oh God, this was incredible! Katie felt a fire igniting hotly in her body as she wrapped her arms around her sister as well, and kissed her again and again and again, unable to get enough of the sensation of their lips merging, gripping, and caressing each other. This was unbelievable! She lost all sense of her surroundings and of time. All that mattered was kissing her sister's beautiful, soft mouth and feeling her body against hers. There was a slight obstacle, though, as Katie still had the chocolate heart in her mouth. It was making it just a little difficult to do everything she wanted to her sister's lips - but then she remembered how it got in her mouth in the first place, and she felt the fire in her burn hotter as well as a wonderful tickle between her legs. She opened her mouth and, with her tongue, pushed the chocolate from her mouth to Lizzie's. Lizzie accepted it and then Katie kissed her fully once again, this time pushing her tongue into Lizzie's mouth to swirl the chocolate around it. "Mmmmh," Lizzie moaned, licking the chocolate with her tongue, and then licking around it to find Katie's tongue. Both girls sighed heavily when their tongues found each other, licking and caressing and sharing saliva. Katie couldn't help thinking how unbelievable this was that she was kissing her sister and sharing a chocolate with her that had just been inside her butt! She felt that tickle between her legs return with a vengeance, and at that very same moment, she felt Lizzie lean into her, pushing her backward onto the bed. Katie felt Lizzie fall on top of her and got a wonderful swimmy sensation as she felt their bodies collide and her sister's weight press upon her. Their kiss broke momentarily, and as Katie looked up at her sister, she could see brown chocolate smears all across her lips and face. There was only one thing Katie could do about that, so she lunged forward and locked lips with her sister again, smearing the chocolate around more, and pulling some of it into her own mouth as well. They panted heavily as they kissed, and it was only making them both hotter. Lizzie pressed down into Katie's body, moving her hips around slightly. Katie wrapped her arms tighter around her sister, pulling her closer, and sighed at the feeling. God, this was incredible. The chocolate was now about half its original size as they kissed with their lips, tongues, and entire mouths. Katie felt Lizzie moving around on top of her more, especially with her hips. It was giving her all sorts of wonderful tickle-y sensations and it made her want to kiss Lizzie harder. She felt like she couldn't get enough of her sister's body against her, and wrapped her legs around Lizzie's butt, locking her feet together and pulling Lizzie down hard against her. Lizzie grunted and began pushing her hips down against Katie's hips, crushing their centers together. A heavy thrill rushed through Katie as she realized that Lizzie wanted her body as tight against hers as possible. There's nothing Katie wanted more either, and she began pushing herself up against Lizzie as well. As Lizzie pushed her hips down, Katie squeezed her legs around Lizzie's butt, and they created a kind of rhythm that felt amazing to Katie. She couldn't help thinking this was like the same thing she and Lizzie had done to the pillows - only now they were doing it with each other! That was so awesome! Katie pushed up against her sister harder and harder, feeling her own breath, as well as Lizzie's, get heavier and heavier. This all felt incredibly wonderful and awesome, except Katie was still wearing shorts. She hated to stop doing all this, but at the same time, she couldn't help wondering how much better it would feel if she took her shorts (and panties!) off. She knew how good it felt against the pillow with nothing else on - how much more amazing would it feel against Lizzie? She had to find out. Katie quickly broke the kiss. "Hold on," she said, letting go of her tight grip around Lizzie's back. She wanted to do this quickly and get back to what they were doing as fast as humanly possible, so she wedged her hands between them, unbuttoning her shorts and hooking her thumbs in her waistband to begin pushing them down. Lizzie, understanding what Katie was doing, rose up and let Katie push her shorts and panties down to her knees. Lizzie gave a little gasp, clearly excited by Katie's actions, and assisted her in pushing them all the way down to her ankles, where Katie slipped out of them. She then quickly dove back on top of her sister, pressing her naked hips against Katie's, and covering Katie's mouth with her own. "Mmmmph," Katie moaned, quickly wrapping her legs back around Lizzie's butt and pulling her down tight against her. Sparks went off in Katie's head as she felt Lizzie's naked sex crushing down tightly against her own. The heat of them pressed together was unbelievable, and she could feel some wetness from Lizzie as well. Or was it coming from her? She didn't really care as she groaned into her sister's mouth and pressed herself harder against her. She quickly fell into a rhythm with Lizzie, just like she'd done with the pillow. Only this time, instead of a pillow, she had her legs wrapped around a warm, naked girl's body - her own sister's - and her sex was pressed into the squishy, wet folds of another girl's. This was way better than a pillow and it was absolutely unbelievable that it was with her own sister. Everything combined together to create the most thrilling, passionate, deliriously hot experience Katie had ever felt. Lizzie was pushing her hips down tighter and faster, and they were breathing heavier and hotter through their noses as they still kept their mouths locked together. Katie squeezed her legs down against her sister with every thrust upward of her hips, crushing their hot mounds together and squishing more wetness between them. The feeling was indescribable and Katie knew this was going to be a pretty big one. Lizzie was grinding heavier in tight little circles, and Katie could feel her sister's butt clenching tightly beneath her calves. Katie knew, from Lizzie's movements, that she was close. Katie was close too. Lizzie's movements grew even heavier until she was nearly thrashing her body down against Katie, bucking her hips hard, pushing Katie down tight into the mattress. And then Lizzie squealed. "MMMMMMPH!" Lizzie cried, the mounds of her butt cheeks hard as rocks as she tensed and shuddered hard. It was so primal and so intense, it pushed Katie over the edge too and she felt her sex burst against her sister, her body shuddering and shaking as she held her sister tight. "MMMMMPH!" Lizzie squealed again, shuddering once more against Katie's body after briefly relaxing. The second one caught Katie by surprise and she squealed back into Lizzie's mouth, feeling an unexpected second burst against her sister. Three more times Lizzie squealed and shuddered against Katie, grinding her hot, wet sex tightly against Katie's and causing them both to climax again and again. Katie lost count after that and couldn't tell if Lizzie's smaller shudders were more climaxes or just little aftershocks. All she knew was that this was the most - and the hardest - she had ever seen Lizzie climax. It went without saying that the same went for her! Finally, as they settled back against the mattress, their bodies going limp, the girls broke their kiss and gasped heavily for air, Lizzie resting her head in the crook of Katie's shoulder. Katie's mind was a jumbled mess. She couldn't really comprehend anything right now. All she knew was that she was lying underneath her sister, naked from the waist down, their warm and very wet crotches resting gently against each other, and that this was the best she could ever remember feeling in her entire life. As the oxygen rushed back into her head, Katie's thoughts gradually returned to her. What had they just done? This was... wow... this was big. She had just crossed a line with her sister. Several lines. Probably all the lines there were to cross! But wow. Was it ever incredible! She couldn't imagine doing this with anyone else in the world, or feeling this close to anyone. This was unbelievable. This was really, really awesome. Katie gently began running her fingertips along her sister's back, tracing her contours and feeling her breathing rise and fall. Lizzie seemed to muster all her strength and rose up, propping herself on her elbows and looking down at Katie. As Lizzie's face came into view, Katie felt a piercing sensation in her chest as she realized she'd never seen such a perfectly beautiful sight in her life. Lizzie was looking down at her, her eyes sparkling, her hair all messed up in a really adorable way, her mouth partly open in an expression of awe and wonderment. There were still some trace smudges of chocolate on her lips, cheeks, and chin. It was clear from Lizzie's expression that she was just as blown away by all this as Katie was. They looked at each other for several seconds before Lizzie uttered a breathy, "Wow." Yeah, Katie thought. That about sums it up. But there was also a more concrete way to put it, that somehow Katie found equally thrilling. She couldn't help breaking into a grin. "I think we just had sex," Katie said. Lizzie's eyes lit up and a gorgeous smile spread across her face as well. "Yeah," she said. "I think we did." The feeling of warmth, and also of excitement, that rushed through Katie's body at Lizzie's confirmation of this was unbelievably thrilling. This was real. She had sex with her sister. And it was awesome. "I've been--" the girls said simultaneously, then dissolved into giggles. "What--" "What were you--" they both started, but ended up speaking over each other. They giggled again. This time Lizzie got there first. "What were you gonna say?" she said. Now Katie felt a little more self-conscious and felt a little blush rise to her cheeks. "Just that... I've been... wanting to kiss you since we put that lollipop between us." Lizzie grinned. "Me too." Katie smiled back. "What were you gonna say?" she said. Now it was Lizzie's turn to blush a little. "Just that... I've been thinking about you a lot lately, and... I didn't know if you felt the way I did... but I think... now... it seems like you do." Katie grinned, feeling her heart melt. "I do." Lizzie bit her lip. She looked so adorable. "I was... wondering if... you wanted to become girlfriends." Katie felt her heart skip a beat. She knew that lots of people in her class were boyfriend/girlfriend. She'd never had a boyfriend and didn't really know if she ever wanted one, but she was always curious about what it was like to be in a relationship. One where you were with the other person all the time and held hands and cuddled and kissed a lot. Never in a million years did she think she would ever date a girl that way, let alone her own sister. But now, the thought of becoming 'girlfriends' with her sister was just about the most exciting thing she could imagine. "Okay," she said, breaking into a grin. Lizzie grinned as well, then leaned down to kiss her. The kiss was soft, sensual, and meaningful. Gently, Katie's hands came up to caress her sister's cheeks as they kissed, causing them both to sigh deeply. After another minute or two, their lips gently parted and Katie settled her head back against the mattress. "I love you," Lizzie said. "I have ever since we looked at those magazines together." Katie felt her heart do a flip and a somersault. "I love you too," she said. "I don't know when, but it feels like I always have." Then she broke into a grin. "But yeah, looking at those magazines was pretty fun." Lizzie grinned. "I just couldn't believe you were into those same kinds of things... and that you wanted to try them... with me." "Honestly," Katie said, "I didn't know I was into them either. But looking at them, with you... it was awesome. And then doing them... Omigod, that was even more awesome." "Is it weird..." Lizzie said, scrunching up her nose a little, "to be into butts so much?" Katie giggled. "I don't know... but I don't really care," she said, looking up into her sister's eyes. "I love your butt and that's all that really matters. That's why I put my heart in it." The girls instantly broke down in giggles. Lizzie couldn't help thinking that was such a funny, clever, and sweet thing to say. She had to think of something to say back. "I love you so much I gave you my heart through my butt," Lizzie said, and the girls dissolved into giggles once again. "Your heart was yummy," Katie said. "And I loved sharing it with you after you gave it to me." "I loved sharing it too," Lizzie said, licking some chocolate off her lips. "I loved everything. Especially the sex part." Both girls felt a little twinge of excitement at the word 'sex,' and the acknowledgment that that's what they had done. There was a twinkle in Lizzie's eye as she grinned at Katie. "In fact," she said, sitting upright and grabbing the bottom of her shirt, lifting it over her head, "I think I wanna do it again. But this time without ANY clothes on." With that, she pulled her training bra up and off as well. Katie felt herself get hot all over again as she watched her sister remove the last piece of clothing from her body and felt the tickle between her legs begin to throb. She felt a strong energy take hold of her. "Okay," she said, pushing herself to an upright position, causing Lizzie to fall back with a squeal. "But only if I get to be on top this time." With that, Katie pulled her own top off, along with her training bra, and both girls looked at each other, grinning, drinking in the sight of each other's naked chests. Katie then dove on top of her sister, their bodies colliding, as she lunged forward and covered Lizzie's mouth with her own. "Mmmmhh," Katie moaned as she felt Lizzie's arms wrap around her, loving the feel of their fully naked bodies pressing against each other. She was pleasantly surprised to feel the tickly sensation of Lizzie's hard nipples against her small boobs. Katie adjusted her lower half so that her legs were between Lizzie's, and slowly began moving her body around against her sister's. She made sure to move her chest along with the rest of her body, brushing her nipples against Lizzie's tight little buds as they kissed, heightening her pleasure and hopefully driving Lizzie wild as well. They played around like this for a while, just kissing and brushing their nipples back and forth, until Katie couldn't stand it any longer and settled her hips down against Lizzie's. "Mmmmm, you're so sticky down there," Lizzie said between kisses. Katie knew there was quite a bit more going on down there than just stickiness - at least with her. "Not for long," she said and then mashed her sex down against Lizzie's. Sure enough, juices oozed out of her and spread around between them. "Mmmmh, oh wow!" Lizzie moaned in surprise. "That's more like it!" Katie giggled and began crushing her hips down against her sister, spreading their fluids around, making everything between them slick and wet. She then leaned down to kiss Lizzie's sweet mouth and began pumping her hips rhythmically against her. "Mmmmh," Lizzie moaned, sliding her hands and arms more fully around Katie's back and spreading her legs wider to make the contact between them easier. Katie couldn't get over how amazing this felt. Everything was so perfect and so right. Before today, she didn't really know what she expected sex to be, but she couldn't imagine anything better than this - completely naked against her beautiful sister, crushing their mouths and their crotches together, their heat and fluids mixing, and pumping away against her, making it all build, the pleasure getting more intense with each thrust. It was glorious and she couldn't believe how quickly she was rising to her peak again. She pulled back from the kiss to look down into her sister's eyes, once again shocked at how hot this simple act was, especially while they were doing it. Somehow, looking at each other like this once again confirmed that this was real and happening. Looking into Lizzie's eyes, feeling her warm breath panting against her, watching her head bouncing gently up and back along the mattress with each of her thrusts - all confirmed the immediacy of it. They were having sex. Katie was having sex with her sister. Right now. This was sex. Real sex. And it felt so much hotter, dirtier, and more right that she was doing it with her sister. As she looked into Lizzie's eyes, Lizzie began nodding her head, seemingly in confirmation as well. Almost like she was saying, 'Yes, this is real.' It made Katie want to pump harder. So she did. "Yes," Lizzie panted. "Yes! Keep going!" Katie could tell she was close. She pumped harder. Katie was close too. And then she realized there was something that would make this incredibly hot moment even hotter, something that would bring them even closer as sisters - something she couldn't believe she hadn't thought of until now. "Lizzie," she panted. "Put your finger in my butt!" Without hesitating, Lizzie reached around, grabbing Katie's butt with her right hand and sliding it down to the base of her cheeks. She wriggled her middle finger between them, making Katie gasp. Katie was pumping away and she could feel that she was sweaty back there, but she knew Lizzie didn't mind. And then she felt Lizzie's finger press against the center of her hole and push itself inside. "Uh! Oh God, yes!" Katie gasped, feeling her sister enter her, her muscles gripping tight around Lizzie's finger. Lizzie, never breaking eye contact, pushed her finger deeper, to the second knuckle, making Katie's jaw drop. "Unh!" Katie grunted, pushing herself harder against Lizzie. Now THIS was intense. Katie couldn't believe how powerful it felt to be looking into her sister's eyes while Lizzie's finger was in her butt. Prior to this, their butt play had almost always been on all fours, with their faces far apart. But now she was face to face with Lizzie as she penetrated her. This felt far more intimate, and somehow far dirtier than what they'd done before. Her brow furrowing, she ground herself even harder against her sister. She knew she was only seconds away. She could feel herself gripping Lizzie's finger tightly with each thrust, sliding it along inside her, the friction driving her absolutely wild. It was incredible. The combination of Lizzie's finger sliding in her butt and her hard, wet clit grinding against Lizzie's wet folds was too much for her. Looking into her sister's eyes, Katie ground down hard, gasped sharply, and burst into orgasm, bucking her hips hard and tight against Lizzie as she grunted and shuddered in a powerful climax. "Ahhhh!" Lizzie cried out, bursting into her own orgasm as she thrust her hips up against Katie while jamming her finger down as far as it would go in her sister's butt. "Unnh! Omigod, UNNNNNHHHH!!" Katie grunted hard, bursting into a second orgasm as she felt Lizzie's finger thrust deeper inside her. She clenched down hard, gripping Lizzie's finger tightly, not ever wanting to let go. The sensation of Lizzie's finger deep inside her butt while she climaxed against her was unbelievable. She continued growling and grunting as she looked into her sister's eyes, pushing down hard against her wet sex, determined to make this last as long as possible. The look on Lizzie's face alone kept her climax going for quite some time. "Ahhhh," Katie grunted one last time as she gave one final thrust before collapsing against her sister, feeling her soft, small breasts press tightly against her sister's, crushing them between them as they panted. Their chests were hot and sweaty, their crotches wet and sticky. Katie could feel each of Lizzie's breaths against her as her chest rose and fell again and again. 'This,' Katie thought, reveling in every single one of these sensations, 'is what sex feels like.' And wow, was it awesome! They panted, catching their breaths, for another couple of minutes. Finally, Katie gathered her strength and rose up on her elbows, looking down into her sister's eyes. She was struck by two things - first, the movement of propping herself up reminded her that Lizzie's finger was still deep in her butt, and second, how utterly gorgeous Lizzie looked after sex. "Omigod," Katie said breathily. "That was amazing." Lizzie grinned. "Yeah," she said, her grin widening into something mischievous. With that, Lizzie pulled her finger out of Katie's butt, causing Katie to gasp sharply. Lizzie then brought her finger up to her nose and sniffed it while looking right at Katie, then opened her mouth, popped her finger inside, and sucked it. Katie's jaw dropped open at her sister's actions. Lizzie was so casual about it all, and somehow that only added to its sexiness. Katie was also shocked that Lizzie just sucked Katie's bare butt flavor - without any candy coating on it. There was no pretense this time. Lizzie really did love the taste of Katie's butt. "You're so dirty!" Katie said, almost reflexively. Lizzie pulled her finger out and grinned. "Yep. That's why you love me so much, isn't it?" Katie paused, shifting her tone. Lizzie had her there. "Damn straight," she said, and leaned down to kiss her. ************************************************ To be continued...
