Date: Sun, 18 Jun 2017 21:40:33 -0700 From: Jojo Starr Subject: My Sister The Dancer JAMIE & NIKKI (ff, inc.) Hi, my name's Jamie Summers. I'm sixteen and live with my parents and twin sister in a mid-sized suburban town. My sister Nikki and I are sophomores in high school and we pretty much do everything together. We're not identical twins, just fraternal, but we still do look pretty similar. There are a few subtle differences between us, though. I've got dirty blonde hair, and Nikki's is more of a light brown. We're both about the same size (although I'd say I'm about half an inch taller), and both have about the same body frame. We've both been dancers since we were little, so we're pretty toned and athletic. The only real difference (well, that I've noticed, anyway) is that Nikki's got a simply amazing butt. Don't get me wrong - mine's okay and all, it's just that hers is like SO much rounder and sticky-outy. God, I really wish I had her butt. She's a little self-conscious about it, but I (and others) keep complimenting her on it, and she just blushes. I'm not sure she realizes how lucky she really is. I keep telling her she's gonna make someone really happy someday with a butt like that. Well, I've already introduced the major character in this story - Nikki's butt - and that's really where it all began. I guess it was maybe a few months ago when I first noticed. My bedroom's at the far end of the hallway, and Nikki's room is in between mine and the bathroom. So I walk past her room whenever I go to the bathroom in the mornings. Well, one morning, I happened to be passing by Nikki's room when she was getting dressed. She was trying to pull up a pair of pants and appeared to be having some difficulty. Thinking it was a bit funny, I stopped and peeked through the crack in her door to watch her. She had got the pants pulled up to the bottom of her butt, where it meets the back of her thigh, and they got stuck. Her butt was so round, she was having trouble pulling her pants over them! After two or three tries, with her bouncing on her toes each time, I realized that I got a funny little feeling watching her. I couldn't explain what it was or why I got it, but I just had to keep watching her. Each time she pulled them up, they squished her cheeks up, making them bulge out. And when she hopped back to the ground, her cheeks gave this tight little jiggle. There was just something about the way that her cheeks bulged out like that and jiggled that I couldn't pull myself away from. After a few more tries, I was actually disappointed when she managed to pull them up over her butt. But I continued to watch as she squeezed her firm round cheeks into her pants and wiggled her hips around to get her pants to her waist. The pants completely conformed to every curve of her bottom and I just couldn't help but keep staring. Soon, she started to turn my way and I had to bolt. All day I couldn't stop thinking about what I saw. It was just so... I don't know... fun to keep thinking about. Yeah, I definitely had the debate with myself about how appropriate it was for a sixteen year-old girl to be thinking about her sister's butt all the time, but I just couldn't help it. I didn't know if I was jealous or fascinated or what. Probably a little bit of everything, I guess. It wasn't long before I was actually TRYING to walk past my sister's room while she changed. Whether it was in the morning, or the afternoon when she changed into her dance clothes, or in the evenings when she changed into her pajamas. I just wanted to see her gorgeous, round bubble butt again and hopefully get a glimpse of it jiggling. I know, werid, right?? Well, this went on for a few weeks and I admit I had a hard time getting those gorgeous round globes out of my head. Then, during our spring break week, our parents told us they'd be going down to the tropics with some of their friends and we'd have the house to ourselves. Even though we had a lot of school work to do, it was still pretty exciting for me and Nikki. The day my parents actually left, Nikki and I didn't quite know what to do with ourselves. We mostly just hung out, ordered a pizza, and watched TV, just lounging around the house. But it felt great to do that. About halfway through the evening, we happened to be watching an awards show that featured some music performers. At one point, Britney Spears performed, and about midway through the song, I started noticing that I was paying pretty close attention to the backup dancers. They were all pretty scantily clad, wearing tight, hip-hugging spandex shorts that showed off about half of their butt cheeks. I couldn't help but stare at the dancers as they bounced around, dipping their hips and popping their butts out - 'twerking,' I guess it's called. The longer I stared, the more I noticed a funny feeling in my belly, getting stronger and stronger. It also got me thinking about Nikki and the way she dances. I turned to her. "You think you might ever want to be a backup dancer?" I asked. "I dunno," she said. "Maybe. I'm at least as good as those girls there." "You think so?" I challenged playfully. "You don't?" she said. "I dunno," I said, smirking. "I'd have to see a side by side comparison." "Well, hit record on the TiVO and I'll show you what I can do," she said, smiling and getting to her feet. This was going to be fun, I thought. I hit record and scooted back on the floor, giving my sister some room. Nikki walked over to the stereo and put in a Britney Spears CD. She hit play, and then stood in the middle of the room in her oversized t-shirt and short cotton shorts. As the music started to play, Nikki danced, gyrating her hips, dipping down and twirling, and thrusting her hips back and forth. I forgot how amazing of a dancer she was. I just sat back and enjoyed the show, grinning as I watched my sister bump and grind to the music. My only complaint was that her shirt went too low and covered most of her best feature. "Wooo! Work it!" I cheered. "Yeah! You go girl!" This seemed to spur her on and she worked harder, thrusting her hips and dipping down to the floor, only to whip her head back up, flinging her beautiful long hair through the air. I continued cheering and she danced through the whole song. "Whew!" she said when the song was over, running her fingers through her hair. She was out of breath, and I could see a sheen of sweat covering her face. "So?" she said. "What did you think?" "That was pretty awesome," I said. "I forgot how well you work those hips." "Oh man," she said, still breathing hard. "I worked up quite a sweat." She pulled at her shirt, which was already starting to stick to her body. Then in one swift motion, she grabbed the bottom of her shirt and pulled it up and over her head, tossing it to the floor. Sure enough, her chest and belly were sweaty too. Damn, she has a nice body, I thought to myself. She was also wearing a thin white bra with some lacy frills on it. I raised an eyebrow at her. "Where'd you get that?" I said, gesturing at her bra. "Oh this?" she said between breaths. "I got this at the mall last week. It's super comfortable." "Pretty hot too," I said, smirking a little. "Thanks... I guess..." she said, looking at me funny. "So I passed the test?" Realizing there was no more shirt in the way, obstructing her best feature (and incredibly thankful for that fact), I thought for a second and said, "Well, almost. You didn't do this." I then rewound the TiVO and replayed the section of the girls popping their butts out and jiggling them around. "What?!" she said, surprised. "You want me to TWERK?" "Well..." I said, "Everyone's doing it these days. And if you did get to be a backup dancer, you'd probably be required to, so..." "Ugh, fine," she said, rolling her eyes at me. She went back to the stereo and selected another song. I couldn't believe I was about to see this! She hit play and turned around in the middle of the room, spreading her legs apart. I scooted back and ogled, barely able to believe this was happening. When the music started, she started gyrating her hips, then began to shake and pop her butt out to the beat of the music, just like the girls in the performance did. But there was still something wrong. her shorts - short as they were - still covered too much of her amazing curves and kept waving and flapping around at her thighs. It was too distracting. "Uh, Nikki-" I said loudly over the music. "What? Am I not doing it right?" she asked. "No, you're fine," I said, "but your shorts are in the way. I've gotta be able to see more of your butt, like the girls in the show. I don't know if you're doing it right because I can't see any jiggle!" "Ugh, omigod," she said, rolling her eyes at me again. But then she did something that surprised me. She left them on, and continued to dance. Then, slowly, she hooked her thumbs in the waistband of her shorts and started pulling them down as she gyrated her hips with her butt thrust out. My jaw just about hit the floor. It was the hottest thing I'd ever seen as she slowly pulled her shorts down - a little bit, then halfway, then a little bit more. Ugh! This was torture! I had to keep reminding myself that this was my sister and I shouldn't be thinking these things, but I couldn't help it. It really was totally hot! Finally she got them down past her cheeks and I think I almost drooled. She kept the waistband tucked just under her cheeks and began popping her butt out over and over, letting it jiggle and bounce in all its bubble-butt glory. Eventually, she slid her shorts all the way down her legs and stepped out of them, standing back up straight in her tight, striped boy-short panties. She then began to sway her hips from side to side, and her butt jiggled each time they hit the peak of her sway. Oh it was awesome! Then she dipped all the way down, leaving her butt high in the air and began popping it lightly, up, up, up. Then she straightened back up, legs spread, and began to jiggle her cheeks in this really tight and fast way, making them look like big mounds of jello. I stared open-mouthed and dumbfounded as the two most beautifully shaped globes of flesh I'd ever seen jiggled rapidly before me in my sister's tight pink panties. I had no idea she could even do that! Then she bent all the way down, touching her hands to the floor, and dropped to her knees with her legs spread. Her butt was so round in this position! My jaw fell even further as she began popping her hips up in this position, making her two soft cheeks bounce up and then slap together with each thrust. She did this over and over again, and looked back at me. When she saw my expression, she smiled and did it more and more. Then she sat slightly upright with her knees still spread, arms down on the floor in front of her, and began jiggling her butt up and down really fast, making it look like jello again. I thought I'd died and gone to heaven. It was the hottest, most amazing thing I'd ever seen. When the song was over, she just stood in the middle of the room, turned her head over her shoulder and smirked at me. "Well?" she said. I think my mouth was still open. I closed it, slowly, and tried to swallow, only to find my mouth was dry. As I shifted a bit, I also couldn't help but notice a significant amount of moisture seep out of me into my panties. "Wo- ugh-ahem!" I coughed, clearing my throat. "Wow!" I said, more successfully this time. "Um... yeah, I think you definitely passed." "Thanks," she said, smiling, and walked over to shut the music off. Then she came over and plopped down next to me, still a little out of breath. "Where'd you learn how to do all that?" I asked, sounding completely blown-away. "Right there," she said, pointing to the screen. "I just watched what they, and everyone else has done." "Do you practice??" I asked, still shocked. Nikki laughed. "No!" she said. "I wasn't even sure I could do it, until I tried it just now." "That was the first time you ever even TRIED it?!" I said. "Mm-hmm," she said, still smiling. I rolled my eyes, nearly falling over. "That was AMAZING!" I cried. "And you TOTALLY have the butt for it too!" "Really?" Nikki said, sounding shy for the first time and blushing a little. "Oh my GOD yes!" I cried. "That was INCREDIBLE! The way you moved, the way it jiggled - UH!" Nikki giggled. "Really?" she said. "You sound like you were getting really into it..." Now it was my turn to blush. "Well... I mean, it was... you just have such an amazing butt!" I stammered. Nikki had kind of a smirk on her face when she saw me blush. It was almost as if she seemed pretty pleased with herself that she was able to get that reaction from me. As I thought about this, I decided to push the boundaries and see how far I could take it. "I forgot how amazing of a dancer you are," I said. "Yeah? Thanks," she said, keeping that cute little smirk on her face. "It was, like, SUPER sexy," I said. "Like, pushing into strip-club lap dance territory." "What?!" she said, whipping her head around to look at me. I blushed again, accidentally, but I could tell she wasn't really mad. "Yeah, totally," I said. "I bet you'd have no problem giving a steaming hot lap dance." "Oh yeah?" she said, raising an eyebrow as if being challenged. "Yeah," I said, still trying to hold back all the blood rushing to my face. "Wanna find out?" she said, smirking, then biting the corner of her bottom lip nervously. I couldn't believe it! My heart started to pound as I quickly thought of what to do next. With only a moment's hesitation, I leapt up, ran to the couch, and plopped down on it, facing her with a grin. "Let's see what you've got," I said mischievously. Nikki got up and put a new CD in the stereo. When she hit play, I recognized it as the 12-minute remix of Britney Spears' "I'm a Slave 4 U." Either she really liked this version, or she was planning on putting on one hell of a show. I leaned back into the couch and spread my legs a little, getting into position. My heart started to pound as I watched my beautiful sister start to dance to the music, lowering her eyes in a sultry glare as she slowly danced her way up to me. She got closer and closer as my heart pounded faster and faster. I couldn't believe how into it she was. Then, suddenly, she lunged forward, putting her hands on the couch on either side of my head and leaned in close. I suddenly felt an incredible surge of erotic energy race through me. I had never seen my sister look so sexy, so determined. I stared up into her eyes as she moved her shoulders and hips in time to the beat, and I could feel the electricity between us get stronger. I wondered if she felt it too. The way she was looking at me, she had to! Was this real? Was my sister really trying to turn me on? All I know was it was sure working! She then moved her chest up, pushing her boobs to within a few inches of my face. I had never been so close to my sister's boobs before - or anyone's for that matter - and I found myself desperately wanting to reach out and grab them - feel how soft and full they were. But before I knew it, she had pulled them back and away and stood back up in front of me, still staring at me with those deep, sultry eyes. She danced for me for a few seconds, then turned around and gave me what I really wanted: a view of her gorgeous, round bubble butt. She began swaying and gyrating her hips around as I watched her gorgeous round cheeks bunch up and stretch out with each sway of her hips. Then she bent at the waist, dipping her upper body down and keeping her legs straight, and pushed her butt out toward me, stretching her panties and making them ride up her cheeks. She then made a slow swivel with her hips, rotating her weight slowly from one leg to the other, allowing me a prolonged view. I was stunned. I'd never seen her butt this close and it held an incredible power over me. My eyes traced every smooth curve and round bulge as it passed directly in front of my face. My heart pounded and my throat went dry. I couldn't believe I was having such a viscerally thrilling experience just staring at my sister's butt. It affected me in such a profoundly erotic way, it's impossible to describe. As she stood back up, her tight panties stayed ridden up and not only could I see more of the bottom of her cheeks, but I could see the tight wedgie she had given herself, making the outline of both cheeks even more apparent. Then, almost immediately, she began to shake them in front of me, bouncing her hips up and down with the beat, causing her cheeks to jiggle wonderfully up and down. Oh God, it was heaven. It seemed like I was on fire - like every nerve in my body throbbed with the desire to feel those amazing cheeks on any part of my body. And then, as if hearing my silent plea, Nikki looked back, saw the look of utter transfixed desire on my face, and leaned her arms back to the couch on either side of me, and gently lowered her bottom to my belly, sliding it downward. I was shocked at how pillow-soft it was, and how intensely hot her skin was. I briefly closed my eyes as I gasped and she pressed her bottom more firmly into me, sliding it down to my lap, where it came to rest on my open thighs. I must have groaned right then, not realizing it, because she quickly shot me a look and grinned. Then she began to straighten her upper body, pressing more of her weight into my lap - and against the top of my crotch. Then she began to gyrate her hips in a circular motion, grinding her butt into my crotch. My eyes rolled back into my head and my jaw fell open. I had never experienced such a feeling of pure, unadulterated bliss in my life. The feel of my sister's amazingly soft, round butt pressed into and grinding against my crotch was beyond anything I ever could have imagined. I felt an intense throbbing between my legs as she ground down into me, and my heart pounded as I felt everything within me begin to rise to a peak. The knowledge alone that my sister was grinding her incredible butt into my lap was causing an orgasm to quickly rise within me, and the sensation of it - the roundness, the softness, the fullness, brought me to a peak faster than I expected. As I looked down at those beautiful, gyrating globes in my lap, I braced myself for what I knew would be an embarrassing - but incredibly powerful - orgasm. And just then - right as I was at the peak - she lifted herself up. I tried to muffle my grunt of frustration as much as I could, but Nikki must have heard me because she looked back at me and shot me a wickedly teasing smirk before bending down and pushing her butt in my face again. I couldn't believe it! Nikki was purposely teasing me! There was no mistaking it now. My heart raced at the thought of what this could mean. Could she tell I was turned on by her? Was she okay with it? Did she want to excite me further? Was she... turned on by this too?! I decided to let myself go a little bit to see how far it would take her. I stared at her butt as she rotated her hips in front of my face. "Wooowwww..." I breathed, just barely audible over the music. Then she stood up, thrust her chest forward and butt back at me, and began to jiggle her hips from side to side, making her butt wobble and shake like a tight little bowl of jello. "Oh my God," I gasped. "That is so hot." She looked back at me, saw my eyes fixated on her jiggling butt, and smiled. Then she did it even harder. After another minute of this, she then bent down with her thighs parallel to the floor and arms straight out at her sides, and began to pop her butt out at me, pulling her hips in, then jerking them back as hard as she could. Seeing her twerk like this at close range was beyond heavenly. I quickly brought the heel of my hand to my crotch, giving it a quick grind. I couldn't help myself. "Oh fff- ...Oh God!" I groaned. Nikki must have sensed movement because she quickly whipped her head around to look at me. Immediately, I pulled my hand away, hoping she wouldn't have seen, but she just grinned again and kept popping her butt out at me, making it bounce up and slap together, bounce up and slap, bounce up and slap, over and over and over. I desperately wanted to touch myself again. My hand was hot and moist just from that quick little grind. I couldn't believe how worked up I was. It was definitely the most excited I'd ever been in my life. I just couldn't believe it was in the presence of my own sister. And then a strange thought occurred to me - maybe it was BECAUSE she was my sister that I was getting so excited. At that moment, I had never felt so terrified - or so utterly aroused beyond my wildest dreams. And in that moment I realized that my sister Nikki was the sexiest creature I had ever seen in my life. Just then, Nikki turned around and faced me, dancing sensually in front of me while looking into my eyes. My God, she was gorgeous. She simply radiated sex. Her beautiful flowing hair, her adorable little nose and lips, those burning sultry eyes, her young slender frame, her round, firm boobs held comfortably in her bra, that flat, toned belly and tiny little waist... oh God. Then she stepped up onto the couch, one foot on either side of me, and stood up with her crotch inches from my face. She continued gyrating her hips, looking down at me. I stared at her adorably sexy panties, noticing the swollen, puffy mound at the juncture of her thighs. It looked so puffy and soft, bulging from her panties. Her crotch came perilously close to my face on a few of her swings, and I caught the heavy, musky aroma of her sex. It made me dizzy as I inhaled it over and over. Then she bent down, squatting over my lap and leaned forward, pushing her boobs in my face. I reveled in their moist, sweaty warmth as she pressed them against my face, pushing my nose between them and cheeks against their softness. Her skin was so smooth! It felt amazing. She then shook her shoulders back and forth briefly, jiggling them against my face, then pulled back and giggled. I was so stunned, it took me a second to remember to smile. Then she slowly lowered herself to my lap again and pressed her body into me, leaning her face close to my ear. God, it was so sensual! "Do you like this?" she whispered into my ear, tickling me with her soft hair. She kept her face there as she waited for an answer, so I nodded. "Want me to keep going?" she asked breathily, sex dripping from her voice. I nodded again. No sooner had I done so than she placed her arm on my shoulders and began to grind around in my lap to the beat. It felt absolutely amazing, but it didn't have quite the same effect as when she was facing the other way. Her butt was further from my crotch, which didn't have a whole lot of pressure on it. But the sensuality of being so close to my sister while she danced in a highly erotic manner was incredible. Our bodies were generating intense heat. She was pulled back far enough that we could look into each other's faces as she gyrated on me, but for some reason she couldn't keep her eyes on mine. Whenever she looked at me, the electricity seemed to get too intense and one of us would look away. It was as if we couldn't quite acknowledge what we were doing. At least not yet. Nikki kept bumping and grinding in my lap, occasionally leaning forward to press her wonderfully soft boobs into mine and rub them around. Then, as the music picked up, she began to grind a little harder and a little closer against me. Every so often, her crotch would press against my abdomen, and I was shocked to feel considerable wetness seeping through her panties. We were both breathing heavily now and as she ground harder, I raised my hands and placed them gently at her waist. She seemed slightly startled at first, but then continued her grind just as heavy as before. Slowly, I slid my hands down to her hips, and when she jerked against me, I put slight pressure on her hips, pulling her toward me. She did this for a while, seemingly encouraged by my hands guiding her. The music got faster and suddenly she shifted her hips slightly so they were up against the side of my hip. When she thrust forward, my heart pounded with the realization that she was pushing her crotch directly into me. Hard. "Oh yes!" I gasped, pulling her hips further into me. Nikki responded by thrusting her hips tighter and harder against my hip bone. I could hear her breathing get heavier and faster. I knew what she wanted, and decided to give it to her. My hands slid down further, coming down to her amazing butt. I shuddered as my hands slid over the soft, round flesh, my heart pounding as I touched my sister's bottom for the first time. I could feel it flexing as she worked her hips against me, her soft flesh bulging out to fill my palms on each back thrust. Every nerve in my body was on fire as I felt my sister's ass, the sheer shape of it causing fluid to seep heavily into my panties. She was thrusting into me heavily now, and it was obvious that she had gotten off the beat, thrusting now purely for the sensations it was giving her. There was no mistaking it now - my sister wanted to get off. On me. She was pumping her hips hard, and her hands gripped my shoulders tight. Then, suddenly, her right hand left my shoulder, and her arm circled around my neck, embracing me tight. Her soft breasts crushed against me as she continued to pump her hips as hard as she could into me. Her breathing was heavy and her body was moist with sweat. I knew it wouldn't be long. "Yes!" I gasped, turning my head toward her ear. "Oh Nikki... please..." I whispered, and grabbed her butt hard with both hands, pushing her against me. Electricity shot through my body like a bolt of lightning when I grabbed her, and I swear I had my own little mini-orgasm just from the feel of her soft flesh filling my hands. Nikki, on the other hand, grunted and bucked against me hard, then shuddered in a very full, very intense orgasm of her own. I held her butt tightly in my hands through it all, feeling every shudder and every hard, prolonged clench. It was the most amazing physical sensation I'd ever experienced. Her flesh quivered and trembled in my hands, clenching tight and briefly releasing, then clenching tight again. I felt every nuance of her orgasm through her amazing round butt. I squeezed it again and again, each time prompting another hard clench from her as she rode out the last waves of her orgasm. Finally I relaxed my hands, and she relaxed her cheeks, slumping limply against me as she gasped for breath. I couldn't believe the sheer eroticism of what just transpired between us. It was without a doubt the most intensely sexual experience of my life. I just sat there stunned, my mind spinning with awe and amazement at what had just occurred. I could feel Nikki breathing heavily, her chest heaving against me, breasts swelling and warming my skin with each breath. I wondered what would happen now. I was on pins and needles, my arousal still incredibly high as I hadn't gotten off anywhere near to the extent she had. I was just about to say something when suddenly Nikki's arm around me tightened and she started sobbing. "I'm sorry," she cried. "I'm so sorry Jamie!" I was stunned. Had she regretted this? I raised my arms up to her back and held her gently. "No!" I said softly. "No, no, no, don't be sorry. It was wonderful! I'm so, so happy right now, Nikki!" She sobbed a little more and then slowly got quiet. There was an awkward silence before Nikki spoke. "You... you are?" she asked. She then pulled her arm out from behind me and leaned back a little to look at me, wiping tears from her eyes. I looked right into her eyes. "Nikki... I've never been happier in my life." She looked at me, studying me, letting these words sink in. She looked so incredibly beautiful right then. The most beautiful person I'd ever laid eyes on. An energy seemed to flow between us as we stared at each other - an intensely beautiful, even terrifying, energy that I knew was affecting us both heavily. My heart was pounding and I knew hers was too. We were both waiting for the other to move. Then, suddenly, in complete simultaneity it seemed, we leaned towards each other. As our faces got within an inch of each other, I closed my eyes, and then, our lips connected. It was a terrifying sensation, kissing my sister, but also intensely beautiful. Her lips were so soft against mine - softer than anything I could have imagined. We just held our mouths together, neither of us moving, feeling each other's softness, and making sure that this was real. It was heavenly and I don't think either of us wanted to move and ruin the moment. My heart seemed to melt at the touch of my sister's lips and I felt closer and more connected to her than I ever had before. Our kiss seemed to last forever as we let all the warmth, energy, and love for each other flow through our touching lips. It was a moment of pure beauty, pure love, and pure perfection. The length of the kiss seemed to be a test for each of us to see if this was really real - everything we were feeling - and whether each of us really wanted it as much as the other did. And we both passed with flying colors. Then, just as simultaneously as we began the kiss, we parted, separating at the same time and slowly opening our eyes to look at the other. Nikki looked so beautiful right then, so dreamy in the afterglow with her still-wet eyes and soft, full lips. It was like I was looking at her for the first time. She - my beautiful twin sister - wanted this as much as I did. It was unreal. It was at that moment that I think I was truly starting to fall in love with her. It filled me with such incredible joy, I couldn't help but smile. Nikki started to smile too, then burst into an uncontrollable, radiant giggle. We giggled gleefully as we realized we felt the same way about each other. It was hilarious. I mean, what are the odds? I couldn't believe I'd found the love of my life and I'd been living with her this whole time! As our giggles died down, we stared at each other and that energy came back. We were able to take maybe one or two breaths before an intense hunger overcame us and we lunged for each other, each of us devouring the other's mouth. This time we kissed open-mouthed, breathing hotly into each other as Nikki's hands came up to either side of my face and my hands went down to grab her amazing butt again. We groped at each other with our lips, enjoying the sensations of sliding them across our sister's cheeks and mouth. We had a natural instinct for each other, locking our lips together in smooth, nearly identical rhythms. As we were just kissing with our lips, there was a tension growing between us, each waiting for the other to take the next logical step. After neither of us could take it any longer, we simultaneously pushed our tongues toward each other and Nikki groaned with satisfaction as she tasted my tongue for the first time. After that, it was all we could do to keep our tongues apart. We reveled in the glorious sensation of our sister's tongue sliding across and massaging our own, and we groped hungrily at the roofs of mouths, undersides of teeth, and everything in between. Tongue-kissing my sister was the most erotic thing I'd ever done to that point, and I milked it for all it was worth. We simply couldn't get enough of each other, desperately exploring every inch of the other's mouth with our tongues and lips. It was the hottest, most passionate kiss I'd ever experienced. The passion between us was so hot, it was starting to get difficult to breathe. After what felt like several minutes of kissing, we pulled back and looked at each other again. There was such a fire and hunger in Nikki's eyes as she breathed heavily, catching her breath, and I knew she could see the same fire and hunger in mine. Then, keeping her eyes on mine, Nikki reached around behind herself and began to unclasp her bra. Then she brought her arms back around and shrugged the straps off her shoulders, letting her bra fall into her lap where her hand swept it away to the floor. In utter disbelief, I looked down and stared at the most perfect pair of breasts I'd ever laid eyes on. Nikki's breasts were firm and pointy, sitting high on her chest with hard little nipples that jutted out towards me. They were about the size of grapefruits - firm and full, seemingly not even needing a bra to support their fullness and roundness. My reaction was pure instinct as I felt her breast pull me toward it. Nikki leaned forward and as I opened my mouth, her breast slid perfectly into it, my tongue dragging from the bottom of her nipple along the length of the underside swell. Nikki gasped loudly and her arms came around the back of my head, fingers sliding up through my hair. I sucked hard, pulling her nipple deep into my mouth, toward the back of my throat. Nikki sighed with pleasure - a sound so heavenly to my ears that I pressed my hands against her back, pulling her into me, my face completely smothered in her wonderful, soft breast. I sucked for all I was worth, compressing her breast tightly between my tongue and the roof of my mouth, feeling overwhelmed and energized by the feel of her soft flesh filling my mouth, seemingly unable to get enough. Nikki gasped over and over as I sucked, running her hands through my hair and pulling my face tighter against her. It was the most erotic thing I'd ever done, and I felt that somehow sucking on my sister's breast was nourishing me, and the deeper I pulled her nipple into my mouth, the more she was filling and heightening my arousal. Nikki held her chest at the perfect angle for my face, seemingly feeding herself to me as she occasionally looked down to make sure I had a good seal on her. We continued like this - me sucking on my sister while she fed herself to me - for several minutes. It seemed to be yet another way we were proving to each other how real and strong this was - how powerfully and deeply attracted to each other we were. It was like a switch had been flipped in both of us during Nikki's lap dance, and now we had completely lost all abandon. Finally, Nikki released her grip on my hair and started to lean back, and I relaxed my jaw, letting her nipple slide from my mouth. I looked at it and nearly half her breast shone in a thick coat of my saliva. Nikki's nipple tightened further, outside the warmth of my mouth, and she pushed her chest forward again. I opened my mouth to suck, but she pulled back before it got there, smirking at me. The corner of my mouth turned up as well, but I kept my mouth open, waiting for her return. I held my tongue out, pushing it just over my bottom lip as she leaned forward again, gently touching her nipple to my tongue and gasping. Then she pulled back and began a gentle rocking motion, slowly leaning forward and touching her nipple to me, then rocking back. Each time her nipple touched my tongue it got harder and pointier, and soon she was sliding the underside of her breast along my tongue and her nipple into my mouth. It came away with a string of saliva connecting it to my tongue, and I think she enjoyed that, trying each time to see how far back she could go before the string broke. The feeling of her nipple going in and out of my mouth was driving me crazy and I desperately wanted to feel her filling my mouth again. After minutes of this agony, she finally - seemingly unable to take it any longer herself - thrust her chest firmly against me again, gasping, "Jamie, please!" My jaw fell and I hungrily accepted her, once again pulling her nipple deep into my mouth and groaned (along with Nikki) at the sensation of her soft young breast filling my mouth. After I sucked from her again, heightening both our arousal, Nikki pulled back and looked at me. "I want to do something for you now," she said. "What would make you happy?" I thought for a second and smirked. "Well," I said, "earlier... when you were giving me that lap dance... and, um... rubbing your butt into me?" Nikki bit her lip, the corners of her mouth turning up just as the slightest hint of a blush crept up her cheeks. "Well..." I continued, "it was really mean of you to get up." Nikki's face immediately broke into a wide grin. "Stay right where you are," she said, and wiggled herself off my lap. As she stood up in front of me, I seized the opportunity to get more comfortable, pulling my tank top off in one motion and quickly wiggling out of my cotton shorts. I settled back into the couch, wearing nothing but my panties. Nikki stared at me, drinking in my body with her hungry, lust-filled eyes. I was so horny I could barely stand it. "A-ahem!" I coughed, snapping her out of her daze. "Right, sorry," she blushed, then turned to the stereo to put in a new CD. When the music started, she came back and stood about a foot in front of me, between my spread legs, her back to me. My eyes, of course, went right to her delicious, round butt. She swayed her hips once, then twice, then stood straight up, sliding her hands sensually up and down her sides. When she slid them back down over her hips, she brought them down around the sides of her full, soft cheeks and, leaning her shoulders slightly back, curled her fingertips just under the bottom curve of her cheeks and began to push them up with her fingers, making her butt jiggle up and down for me. "Oh my God," I gasped, staring slack-jawed at her beautiful, bouncing flesh. She turned her head back to look at me, glanced down to her butt to see what it looked like, then smiled as she looked back at me, obviously pleased with herself and the reaction she was getting from me. Then, dropping her hands back behind her, she took a step in either direction, spreading her legs and straightening her back. She then began the most furious side-to-side hip jiggle I'd ever witnessed, causing her cheeks to wiggle and shake so violently they smacked into each other audibly several times. My jaw dropped and I drooled considerably, not even caring, as I stared fixedly at those gorgeous, wobbling, sexy round cheeks. Then Nikki dipped down with her legs again, pushing her butt out at me. She backed up until her legs were almost touching mine and, with her hands on her knees, lowered her hips just a few inches above my crotch. I was on fire. I couldn't believe how sexy this was. Then she began to twerk - hard, - popping her butt up and down, over and over again right over my lap. I couldn't believe this display of pure, jiggling sex right in front of me. And it was coming from my own sister! I could feel more and more cream seeping into my panties, completely soaking the crotch. I watched her cheeks bounce high up, then smack together in rapid succession, over and over again, and I wondered if I would be able to hold back at all if those cheeks actually touched me. Then Nikki straightened her back and put her arms back behind her to rest her hands on my thighs. She looked back at me with a wicked grin and began to bring her bottom slowly back, until those two amazingly soft globes of flesh touched and then pressed into my hips and crotch as she backed her weight into me. Both cheeks of her butt seemed to surround and then squeeze against my swollen, throbbing sex as she began to lean back into me. My mouth opened wider and a noise involuntarily came out of me. "Aah - Unh - Uuuuuuuuuuunnhhh," I groaned as she began to settle back into my lap. The pressure of her soft flesh on me was unbelievably intense. I was hot. Throbbing. On edge. I didn't know how much more I could take. Then Nikki began to lean back further, pressing her smooth back into my soft, bare breasts with most of her weight on her arms, and began sliding her butt up and down against my crotch. I gasped sharply. "Ah- Aaaahhhh! Oh! Oh God!" Her globes were right over my sex, rubbing firmly against it. It was heavenly. Her movements were slow and sensual. If she'd gone any faster or put any more weight on me, I'd have lost it. But she just slowly massaged me with her butt, knowing full well how incredibly hot she was making me, keeping me right on the edge. Having my sister pressed to me like this, feeling her movements, was beyond erotic. I couldn't believe anything could feel so good. Then, without warning, Nikki pressed nearly her full weight into me as she raised one leg up and over mine, leaning all the way back into me at a slight angle. My hands instinctively went to her sides as I gasped, and as she settled into place, she began to lift her hips slightly, only to rotate them in a circular motion, bringing her butt down firmly into my crotch and grinding it around. My eyes rolled back into my head as she repeated this motion, slowly rotating her hips, making sure on the downward motion to grind her butt into me as firmly as she could. I trembled. I throbbed. I felt everything within me rise. I could feel every tiny muscle clench and movement of her butt as it ground down against me. "AH! Ffff! Nikki! Oh God!" I gasped. This only made her grind harder into me, the tight fabric of our panties causing tiny vibrations against my throbbing clit. I gripped her hips firmly in my hands, pulling her tight against me as I felt the most amazing sensation begin to rush through my body. She continued to grind with limited movements as I held her tight. "Aah! Uungh! Fffnnh - omigod, Uuuuunnnhhfffff!" I grunted as she pushed me well over the edge and I began to buck my hips tight and hard against her soft butt. She held herself still for me as I pulled her down tight against me, allowing me to buck myself against one of her tightened bulges. "Unnngh! Rrruungh! RRrrruuuuunnghfff!" I growled as I released an insane torrent of hot cum all over her tight butt cheek. I rode out my orgasm as hard as I could and then collapsed, utterly and completely spent, into the couch, panting heavily. After minutes of heavy breathing and an utter, glowing bliss flowing through my body, Nikki, still in the same position, turned her head toward me. "Oh my God," she said. "That was the hottest, most intense thing I've ever heard." I was still unable to speak, but if I could, I would have told her it was the hottest, most intense orgasm of my life. "Are you okay?" she asked. Then, with a slightly embarrassed tone in her voice, said, "You, um... completely soaked my butt." "I... I did?" I managed to gasp. "Uh-huh," she said, and swinging her leg back around, began to stand up. My eyes widened in shock as, sure enough, I saw an incredibly wide dark stain across nearly the entire rear of her panties. I then looked down between my own legs and saw that my entire crotch was soaking wet, and there was a dark wet spot on the couch as well. "Oh my God!" I gasped, mustering the strength to lift myself up and get to my feet. "We gotta clean this up!" Nikki just grinned. She bent down and picked up my shirt off the floor and laid it down over the wet spot. "Not now," she said with a naughty grin and gently grabbed my shoulders, pushing me back onto the couch. I fell back in a limp heap. "The music's still playing," she said, smirking as she turned back around and got down on all fours. I stared at her in a complete daze as she began to sway and work her hips around again, shaking her butt ever so slowly and sensually. She looked back at me to make sure I was watching her and then got up on her knees, hooking her thumbs in the waistband of her panties. This got my attention and I watched as she slowly began teasing me, gyrating her hips around and stretching her waistband without actually pulling it down. Then, she bent down low and pulled with her thumbs, her butt crack slowly coming into view, followed by the most amazingly smooth, round curves of flesh I'd ever seen. She straightened back up as her panties fell to her knees, and then she dropped forward into a push-up like position, pumping her hips up and down for me, allowing me to see her full, bare cheeks in all their glory. I could slowly feel energy coming back to me as I watched her work her hips. Then she pressed her hips to the floor and began to slide herself across the floor, rolling her panties down past her knees. God, it was hot. When they got to her ankles, she pulled one ankle out, then, raised her other ankle, panties dangling from it, and swung it around, tossing them off to the side. Just that simple act of her panties being flung away from her perked me up like nothing else. She was completely naked now, not a single piece of clothing on her. I couldn't believe how sexy she looked as she turned her head over her shoulder and shot me a naughty look. My heart began to pump stronger and harder now and, remarkably, I was starting to feel another tingling between my legs. Nikki then rose back up on all fours and began to shake and bounce her butt for me, twerking occasionally, giving me the faintest peek at the puffy little slit between her legs. My mouth hung open and I decided not to hold back. My hand slid over my thigh and into the valley of my wet crotch as I cupped and squeezed my mound, pressing the heel of my hand firmly into it. Nikki glanced back and when she saw where my hand was, she began to rock back and forth on her hands and knees, taking deep bends forward and back, pushing her butt out at me, giving me an even better glimpse at her glistening, pink sex. I could now see that her lips were not only swollen, but slightly open as well, her inner pink lips, glistening wetly, beginning to push out between them. I rubbed myself harder as I stared between her legs, unable to decide which was making me hotter - the slit between her legs or her glorious, shaking rump. Nikki then sat up on her knees in a kind of squatting position and began to shake her hips up and down, making her butt bounce again. She looked back at me as she did this, watching me rub myself through my panties. "You like this, don't you?" she said, a sly grin on her face. I nodded. "Wanna see what it feels like?" she said. My heart instantly skipped a beat. See what my beautiful sister's hot, bare, pantiless ass FEELS like? Hell yes I did! "Come and get it then," she said, lowering back down onto all fours. I instantly got up from the couch and began to get down on my knees behind her. "Wait," she said, bending down, moving her butt away from me. "You gotta take your panties off first," she said, grinning adorably as a blush crept up her face. I swallowed dryly and quickly hooked my thumbs in my panties, pushing them down my legs and stepping out of them. I was instantly struck by the strong musky scent emanating from between my legs and I knew Nikki could smell it too. I blushed, slightly embarrassed, but I was too horny to really care. Nikki looked back at me and smiled, then rocked back on her hips, pushing her butt toward me again in invitation. I dropped to my knees behind her, looking down at those wonderfully smooth cheeks. My hands stretched out in front of me and as I placed them on her amazingly soft warmth, I let out a long, drawn-out sigh, briefly closing my eyes as I gave a little shudder. Then, looking back down at her, I slid my hands over her flesh as she leaned back toward me. Then, purely on instinct, I grabbed her hips and pulled them back into me, pressing those oh-so-soft cheeks into my hips and crotch. My mouth fell open at the sensation. "Ohhh Jamie..." Nikki groaned. After that I was on autopilot. My body and my urges took over as I began to rub my hips and crotch up against her butt, pulling her back into me. Nikki, seemingly in tune with me, began to straighten herself up more, allowing more of her soft flesh to press into me. She began to get into kind of a squatting position, but still leaning forward on her arms, and began to rub her butt up and down against me. I gasped sharply as I gripped her hips, guiding them as I pressed my crotch forward against her. She was stimulating me directly again with her ass cheeks. My mouth fell open as I continued to work her hips around my crotch, feeling more energy within me begin to rise. Nikki looked back at me, making sure what she was doing was pleasing to me. There was no worry of that, as I'm sure she could tell from my facial expressions. She then began to gyrate her hips in a circular motion, as she had on the couch. "Oh God Nikki!" I gasped. "Oh shit!" Nikki grinned and began to grind her hips harder back into me. She was grinding so hard and tight into my crotch, I barely had to move at all. I simply stood there on my knees, my mouth hanging open, feeling her amazing butt rub, push, and grind against my throbbing, aching sex. It was incredible - possibly even better than when I was sitting on the couch, simply because we had our panties off and it was now skin-to-skin contact. Her flesh was so warm against me and so smooth, it was unbelievable. I pulled her hips tighter into me, and she began to wiggle her hips back and forth into my crotch tightly. I leaned forward, mouth open, stunned at the intensity of her movements. "UUUNNNHH!" I grunted, nearly falling into her back. Nikki grinned widely, loving the effect she was having on me, and began to straighten herself up, moving me up as well, as she continued her strong, tight hip wiggle. I was gasping wildly now, and she must've known I was close because she pushed back even harder, wiggling her hips even faster. "UNNG! OH GOD! NIKK-- UUUUUUNNNNNNNNNNNNNNGGGHHHHHHH!!!" I grunted as I came all over her tight, grinding butt. Nikki slowed her wiggling while I came, gyrating her hips and butt around my crotch as I rode out my orgasm. It was amazing - like she was anticipating my every need by giving me exactly the right amount of stimulation. As a result, my orgasm was longer and more drawn-out than the last one, and I gasped over and over, pulling her hips tight against me. "Oh! Oh God!" I gasped, and with one final deep breath, I fell back on my butt, my arms barely catching me, as I panted over and over, catching my breath. "Oh Nikki!" I panted. "That was... That was..." I was simply unable to find the right words. And just then, Nikki began to turn around on her knees, and look at me directly. She had such a burning, sultry look in her eyes, I almost couldn't believe it was her! I had never seen her look so sexy, so lust-filled, and so unbelievably confident and determined. My eyes began to widen... and then she pounced. She pushed me down onto my back so hard, I nearly rolled over backwards. My knees went up in the air and just before they came down, she caught them and held them back with her hands so my thighs were nearly against my chest, and leaned down over me, staring hotly and passionately. "Do you know how long I've wanted this?" she breathed. I was speechless. Did I just hear her right? As I was trying to process her words, I barely noticed her body moving around above me. "I need this so bad Jamie," she said as she spread her legs and began to move her crotch over mine. Still holding my legs back, she began to settle herself down against me, pressing her burning hot sex down against my limp, wet one. My eyes shot wide open at the incredible sensation as Nikki groaned deeply. The sensation was incredible! Our sexes, mashed tightly together by the weight of Nikki's body was unbelievable. I was completely wiped out by the orgasm I just had - not to mention the one I had before that, but as Nikki began to lean down over me while keeping her hot, open sex tight and flat against mine, I couldn't help but feel yet another stirring somewhere deep inside of me. Nikki's hot, sultry eyes staring directly down into mine helped a bit too. "I want us to get off at the same time," she said, and then began to slide her hips up and back against mine, rubbing her hot pussy tightly against me. My mouth dropped open again. Every nerve in my body came alive and stood at attention. I couldn't believe how incredible it felt. I looked into Nikki's face and her brows furrowed and mouth hung open. I could tell the feeling was just as intense for her as it was for me. She began to ride me with an intensity I'd never seen in her before, her hips thrusting urgently, arms tensing as they held up her upper body. I glanced down at her beautiful firm breasts swinging and bouncing back and forth as she thrust and felt my heart rate quicken. As thrilling as it was to watch her breasts, I couldn't keep my eyes off hers for long. Her eyes burned with an intense determination, completely filled with lust and arousal as they stared back down into mine. My God, she was sexy. Something about looking into each other's eyes as our sex parts slid and ground against each other produced an incredible energy I can't quite describe. We were connected - in our gaze, at our cores, and at our loins. The energy was so intense I could barely stand it. There seemed to be a direct connection between the look on my sister's face and the sensations going on between my legs. The more I stared at her, the more intense it got. She was thrusting faster now, the lubrication we were both producing making it easier for her to slide back and forth. My mouth fell wide open involuntarily. "Aaaah-uuunngh!" It just came out of me. Nikki stared down at me as she thrust, her eyes getting more intense. "Oh Jamie! Jamie! I'm almost there! Will you cum with me?" The words alone almost sent me over the edge. I couldn't speak, so I just nodded as forcefully as I could. Then suddenly, I found my voice. "Quick! Hurry!" I gasped. Nikki then bore her weight down on me, grimacing, and began wiggling her hips around in that tight little grind she did on me earlier, only this time it was more side-to-side with her full weight pressed down against me. I felt her slick, puffy lips rub and slide tightly against mine, opening them up and exposing my clit. My jaw fell even wider - if that was even possible - as she continued to grind tightly against my clit. My hands went to her thighs, gripping them tight as I braced myself. She knew what was coming as she stared into my eyes, furrowing her brow tighter and biting her lip. "HHHHAH! OH GOD!" I gasped. "Jamie! Jamie! Oh Jamie!" Nikki panted and then thrust her hips tight against me, pushing me well over the edge and beyond. "UUUUUUUNNNNHHHHHHHH!" we both squealed as we exploded against each other, bodies trembling and spasming. I gripped Nikki's thighs tight as she continued her attempts at thrusting, increasing the intensity of both our orgasms. "UUUNNNNNGH! UUNNNNNNFFF!" we squealed over and over. It was the most glorious, most intense orgasm of my life, and I spent it staring into my sister's beautiful eyes, watching her face contort in orgasmic bliss. Just watching her as she came gave me another orgasm and I grunted hard, signaling to her that she had done it to me all over again. We screamed, cried, and grunted for what seemed like minutes in a series of seemingly never-ending orgasms. The energy between us was stronger than anything I've ever felt in my life. But eventually, the need for oxygen overcame us and Nikki's thrusts slowed to a trembling halt. At that point, still staring into each other's eyes, we gasped desperately for air. Nikki's face was slick with sweat and her hair stuck to her face in clumps as she panted and gasped for breath. I'm sure I looked more or less the same. After a minute or two of breathing extremely heavily, our breaths began to slow, and Nikki leaned down and pressed her lips to mine. She melted into me, sliding her thighs down and allowing me to relax my legs as I slid my hands up her back and wrapped my arms around her. We kissed softly, lovingly, but full of incredible passion. It was as if I could feel my sister's soul flow through her kiss and into me. We became completely one at that moment and it filled me with such incredible emotion I began to cry. Tears leaked out of my closed eyes and my chest bounced silently as I sobbed with happiness. Nikki broke her kiss to look down at me. "Jamie?" she said, concerned. "I'm sorry," I said, wiping tears from my eyes. "I'm just so happy. I never thought it would feel like this. I just love you so much and I'm so happy we did this." Nikki started tearing up as she listened to me. "Oh Jamie! I love you too! I've always loved you, but I just never knew how to do anything about it! All I've ever wanted was to make you happy." "You have," I said, on the verge of sobbing again. "You've made me more happy than you could possibly know!" Nikki broke into a grin and sort of laugh-cried, tears in her eyes once again. That was all it took. We both collapsed into sobs, laughing and crying at the same time. We held each other tight, letting it all out, overwhelmed at the love we felt for each other. Nothing could come between us now. We were one, and we knew it. It was such an amazing feeling. I was so deeply in love with my sister, I wanted to do everything with her, be everywhere with her, and make her feel like she was the most beautiful girl in the whole world - and I knew she felt the same about me. My mind swam at all the emotions we would share as a result of how close we'd become, and now that we'd introduced sex into the mix, I couldn't wait to find out how much pleasure we could share with each other. I wanted to explore every possible inch of her body, worship her, give her the kind of pleasure fit for a queen or a goddess. I loved her with every absolute inch of my body. Nikki and held each other like this for quite a while, just basking in the feel of our bodies against each other, kissing tenderly, and talking about our feelings for each other. We talked about when the feelings began for each of us, and I confessed to being incredibly turned on by watching her trying to squeeze into her tight pants. She giggled and confessed she had no idea I was so aroused by her butt. I told her it was the sexiest thing I'd ever seen and I wanted her to use it constantly in our love-making sessions. With a mischievous grin, she said she thought she could arrange that. We talked for hours, and by the end of the night, Nikki shyly admitted to me that she was falling in love with me. I told her I was falling for her too, and then we made love again before finally going to sleep in each other's arms. ***************************************** The next morning I woke up and Nikki was still sleeping. I lay there looking at her, simply amazed at how beautiful she was. I couldn't believe how lucky I am to have a sister like her. She was so sexy and sweet and passionate... and she was into me. Really, really into me. Not to mention she had the most amazing ass on any human being worldwide. I started to get horny again as I stared at her and I gently leaned in to kiss her on the lips. I held my kiss softly, and soon she was kissing me back and moaning as she woke up. I slid my hand around her waist, pulling her closer to me. Nikki moaned louder when I did this and began kissing me more passionately, pressing herself to me and wrapping her leg around my hip. A few seconds later, she was pushing her hips against me, trying to grind herself against my skin. I leaned my hips toward her and she groaned as she pressed her hot sex against me and began grinding around. I was surprised at how wet she was already and adjusted myself so that she would have the best possible access to my skin as she ground herself firm and hard against it. Nikki quickly picked up the pace and within seconds she was cumming, breaking the kiss to cry out as her orgasm hit her. I pulled her hips against me as she came, assisting her orgasm and drawing it out. Nikki finally let her head fall limply to the pillow, catching her breath. I smiled at her. "Morning cutie butt," I said. "Was that nice?" "Mmmm, yeah," she moaned, absolutely glowing. I let her rest for a minute, then gently leaned in to kiss her again. Nikki surprised me by hungrily kissing me back, then staring deeply into my eyes. "So," she said, a smile forming at the corner of her mouth. "How would you like my 'cutie butt' to pleasure you?" She emphasized my pet name for her, implying she was planning to use just that part of her to pleasure me. I smiled at her expression and felt a surge of energy rush through me at her words. "Hmmm," I said thoughtfully. "How about you get on all fours to give me some inspiration?" Nikki grinned, and in one swift motion, threw the sheets off her. She seductively crawled onto her hands and knees, pointing her butt at me as I sat up in bed. She looked back at me with a wry smile and began to wiggle her hips back and forth teasingly. "Oh my God," I groaned, staring at her sexy round butt. As if an imaginary force was pulling me toward her, I rose to my knees and approached her, reaching my hands out to grab her soft, full cheeks. "Uuuuunhh," I groaned and, sliding my hands around to her hips, gripped them and pulled them back against my crotch, smacking her cheeks into me. My eyes flew open in amazement as her soft cheeks smacked against my swollen sex. "Oh my God!" I gasped. "What?" Nikki said, turning her head to look at me. "Maybe..." I said, gripping her hips again. "Maybe you could..." I pulled them back, thrusting my crotch forward until they connected with another loud 'SMACK.' "Oh my God!" I gasped again. "Yes!" I began a rhythm, and Nikki seemed to catch on, rocking back and forth on her hands and knees, smacking her butt against my crotch as I groaned. It felt incredible! I was really getting into it, smacking her against me over and over as I gasped and grunted. After a minute or two of this, Nikki looked back at me with lust-filled eyes. "Do you think you can cum?" she asked. My heart skipped a beat. God, she was sexy. "I... I think so!" I grunted. "I just... Unh! Maybe if I..." On the next smack, I grabbed the sides of her cheeks, pressing them inwards against my crotch. They seemed to 'pinch' my bulging mound, crushing my clit tightly between them for the briefest of seconds. "Oh God!" I screamed. "Yes! I can! Keep going! Harder!" I cried out to my sister. Nikki kept rocking back against me, harder and harder, and on every thrust I pressed her cheeks inward when they hit me, squeezing them around my clit each time. "UH! Yes! Oh God! Nikki! FFFfff - UUUUUNNGHHHHH!" I grunted as the smacks brought me closer and closer. "UNH! Faster Nikki!" I cried. Nikki worked harder, pushing herself back into me as hard and fast as she could. The smacking kept pinching my clit and suddenly I felt everything rise. "UNH! Oh God! Nikki, YES! UUUUNNNNGGHHHHH!!" I grunted as I felt myself explode. I kept pulling her hips into me and Nikki kept rocking hard and fast as I came, and soon the smacking sounds got wetter and wetter as my cream flowed out, splattering against Nikki's naked butt with each thrust. It was too much. Finally I held her hips tight, keeping her still, and bucked my hips frantically against her soft cheeks, smacking my outward-thrust sex directly between their tight softness at incredible speed. My mouth fell open at the sensation and I accidentally drooled down onto her butt. "UUURRRRUNNGGGGH! UUNNNGHHH!" I growled as the final wave of my orgasm rushed through me. After a few hard, final wet smacks, I collapsed, leaning forward over her, gasping for breath. After a few minutes of panting, Nikki took a deep sigh. "Wow," she gasped. "That was freaking hot." I giggled. "Yeah. Yeah it was." "I didn't even know you could get off like that," she said. "I didn't either," I said, still gasping for air. "I just... couldn't help it." We both giggled. The rest of the day we played around with each other, exploring each other's bodies and getting ourselves off in any and every position we could think of. We were so into each other, we simply couldn't get enough of each other. ************************************ Six years later.... ************************************ I can't believe it's been six years since that amazing weekend. A lot has changed since then, and in some ways, I guess a lot hasn't either. For starters, Nikki and I are still together and are still very much in love. It's crazy. We've been together six years and it still feels like we just discovered each other. I guess part of it is probably the fact that we know two sisters aren't supposed to be in love with each other like we are, so the fact that it's a social taboo actually excites us more and definitely keeps our sex life alive and strong. But more about that in a minute. When we turned 18, we made plans to move out and get an apartment together. It was almost another year later though before we actually made it happen. Our parents think we got a place together so we could support each other while we went to school, but obviously we have other reasons they don't know about! Nikki and I both enrolled at the local university, and we're in our last year of our studies now. I'm majoring in design and aesthetics, and Nikki's majoring in communications. About two years into our program, we realized that funds were getting pretty tight, so Nikki said she'd try to find work. What she found shocked me, although I probably shouldn't have been surprised. She said one of the girls in her class was a dancer at a local club and hinted that Nikki might be good at something like that. As soon as a position opened up, Nikki auditioned, and got the job on the spot. Of course, she cleared it with me first. I have to admit I was a little apprehensive about her showing her body off onstage, but the money was good, and she was of course very clear that I was the only one who would be able to touch her sexiest parts. I eventually gave in, mainly because I trusted her. And of course, her butt is still in amazing shape and looking better than ever. It's probably what brings in most of our income, as a matter of fact! But true to her word, Nikki hasn't let anyone touch it but me. And I sure take every opportunity to do so. If anything, I've only fallen more in love with Nikki's butt over the years. Having an insatiable butt fetish as I do, I'm always checking out other girls' butts - on campus, at Nikki's work, and anywhere I happen to be in a general crowd of people. And while there are some nice butts out there, the simple fact is that none of them can compare to Nikki's. Nikki's is just... perfect. That's all there is to it. I can't believe how lucky I am not only having a sister with a butt like that, but having a sister who will let me grope and squeeze and rub myself against that amazing butt for my own perverse pleasure. I truly am the luckiest girl in the world!
