Keywords: inc,fic It was one of those days, you know, where my lust had just been out of control. You know, the days where you're just desperately horny. I had woken up horny (not that I don't always), feeling desperately in need of a fuck, and despite giving my hardon some repeated attention, my desires refused to subside. And it only got worse. Perhaps it was my desires skewing my vision, but the universe seemed to be playing a cruel joke as I began my day. The ratio of stunning women I encountered was unreal. Seemingly everyone I met or walked past on the street was absolutely beautiful. Slim brunettes with perfect asses on every corner, constantly reminding me how desperate I was. I had been single for a while, and was doing fine most of the time, but days like these were a bit much. What could I do? I suffered through it, drooling over every ass, every perky pair of breasts, every curve, and every red-lipped grin I saw. I tried to keep my mind on more pure subjects, to distract myself from the misery, but the universe wasn't having it. I needed to get home for a release, or even just an escape from all the fantasy inducing people. Until I could, I would give into it. So I admired wherever I went, taking in all the sexual beauty, realizing that we're all sexual creatures, and underneath all the clothes, everyone has genitals, and goddamn I wanted all of them. Of course this didn't help and when I finally got home, I was throbbing before I had even walked through the door. To my dismay, everyone was home. The house was abuzz with activity as my mom, dad, and sister went about their business. I forgot it was Friday; everybody gets home early on Friday. As they greeted me one by one, I zoned out, trying to find a way to get some alone time, but it wasn't going to happen, not right away anyways. I settled for the TV, hoping that a show could distract me for a while. I plopped on the couch and surfed for something interesting and distracting. After ten minutes, it actually kind of worked. My desires hadn't vanished, but my need to release the tension was at least pushed to the back of my head. I started to relax. Then my sister came in. She was eighteen, only a year younger than me, but I had always been the older brother, or at least that's how I thought of her. She seemed young to me, my kid sister, and we had always been close friends, sharing this dynamic. I had not once thought of her in a sexual manner. Sure, I realized when she began to develop, and I saw her body change from a girl's into that of a young woman, and I knew that she was beautiful, even sexy, objectively, but those feelings were for someone else. But again, my desires were intent on skewing my perceptions, and as she walked across the room to join me on the couch I saw her curves in a whole new light. She really was beautiful, and like everyone else on this planet, she was a sexual being. Her hair was long, silky and dark brown, framing her face perfectly as she smiled. And her eyes glistened above reddened lips. Had she dressed up today? Her skin was tanned, and was accentuated by a blue button up shirt she wore. It was loose fitting, but shaped right, and I could make out the subtle shapes of her breasts beneath it. And her bottoms were anything but loose. They were leggings in fact. The matte black fabric hugged the slender forms of her legs. They were toned, but soft, and led to her shapely ass. And she really has a perfect ass. The tight spandex of her leggings curved up subtley between the two rounded teardrops of her butt. There was no impression indicating her underwear...she must have been wearing a thong. That's where things shifted, or became more acute. She must have been wearing a thong. Something switched,a dn I was imagining my sister's panties, hugging her most private part, her most sexual part. Kelly was a sexual being, like everybody else on the planet.. Suddenly, my desires were back, and they were focused. I felt uncomfortable as Kelly sat next to me. Our usual dynamic felt gone, and for a moment I felt guilty. But as I lapsed in my attempts to avoid my gaze, the shape of her legs crossed and coalescing at the confluence of her pelvis eclipsed anything else in my mind. She tried to talk to me, but I couldn't remain coherent. My responses were terse and cordial, not our usual honest discourse. After a moment, she seemed to realize I wasn't in the mood for talking, and settled in to watch the show. Again I felt bad. But I continued to glance over. She was driving me crazy. The way she crossed her arms, or the softness of her hands, even just the slight shape of her bra showing through her shirt added to my desires. I had forgotten about the show, and was enthralled in my sister. My attempts to shift my mind became weaker and weaker, and my fantasies hotter and more explicit. I was no longer just undressing her in my mind. I was teasing her, and feeling her breasts, kissing her hard, and grabbing her ass. I was between her legs, licking her and tasting her cunt, and I was fucking her. I had a strange sense of guilt through the whole thing, but it was too pleasurable to stop. When Kelly got up to grab a drink from the kitchen, the proximity of her perfect ass to my face pushed me over the edge. I bolted upstairs to the bathroom. Again, my cock was a rock before I had even made it all the way up the stairs. I found myself undoing my pants frantically as I walked down the hall, and I was stroking away by the time I sat down in my sanctuary. Furiously I pumped at my aching hardon, trying to keep the image of Kelly's spandex clad ass burned into my mind, and then it hit me. Kelly's hamper was right in front of me. My heart skipped a beat, and then made up for it by beating twice as fast. I began to shake, still trying to convince myself that I had a choice of whether or not I was going to do it, but even as the thought crossed my mind my hand was on the lid and I was going for it. I knew I was safe in the bathroom, everybody else was downstairs and had probably forgotten I even came up here, but I was still silent, moving things slowly and secretly, trying not to be detected. Luckily, I didn't have to look hard. It was right on top, pink and soft, with a lace waistband. Kelly's thong was there, and my cock was harder than ever. I grabbed them, just to look at them, to see what she wore under those leggings, but they were so hot, wrinkled slightly and stuck in the shape that her body made. I turned them around and opened them, so that the soft crotch of the panties faced me. It was coated with a thin translucent white crust, a line really, that mimicked the shape of her sex. Kelly had worn these. This thong had spent a day and maybe a night nestled against her most sexual parts, held firmly against her ass and her pussy. I stared at this surrogate object of my desires, this evidence of Kelly's sexuality a moment more. And then I don't know why I did it. It felt like the natural thing to do. I had only wanted to look at them, but now with them in my hands I knew there was more. I brought them to my face. Intuitively I pressed the gusset to my nose and took a breath. My cock felt like it would explode as I was presented with the most delicate, musky, sweet smell. Kelly's scent very nearly scent me over the edge, but I held off, wanting to savor the scent of my sister's pussy for a moment longer. ...But not much longer. After a few more deep inhales, and a few final strokes I came with a force I did not know I had, shooting gobs of cum all over the area around me. Almost immediately I felt guilty. I threw the panties back in the hamper and looked around sadly at the mess I had made. I felt dirty cleaning it up, knowing that this seed was spilt to the thought of my sister. I avoided looking at the hamper--the image of the panties brought the guilt back up. I stayed upstairs for a while longer, not wanting to confront Kelly, but eventually it was dinnertime and I was forced to leave my hideout. I trudged down the stairs holding my head down, and was greeted with a cheerful family. I didn't look at Kelly. For the first fifteen minutes or so of dinner, I didn't say much, or anything at all really, but the food and the conversation, along with time passing helped break me out of my funk, and by then end of the meal I was back to my normal self. Even talking with Kelly felt back to normal, and better yet, I could look at her without getting a hardon. I guess the guilt was good for one thing. I felt like the desperate horniness that had plagued me all day had gone, and I thought, despite the slight uneasiness at the back of my head when I engaged with her, that my relationship with Kelly was unaffected. The panties were a one-time thing, I thought, and got cheery at the idea. But we all know how this works. Whatever the reality, I felt happy, and balanced, and helped clear the table before heading out to watch some more TV. My family came in and we had a normal night for the next few hours. Kelly sat next to me on the couch, and we joked like we normally do. She was still wearing the leggings, and I felt my eyes start to drift a few times, but passed it off as residual. Things were good. After a few hours, mom and dad went to bed, which left Kelly and me alone on the couch. I felt a little flutter as the realization hit me, but again just passed it off as anxiety. We were siblings after all. Kelly and I have a sort of routine where we watch weird documentaries after everyone's in bed. A lot of them are really bad pseudo-documentaries, a lot of them are just weird, and everyone else seemed to hate them, but not us. We loved them, for whatever their quirks, and it had become our thing: when the parents go to bed, we switch to documentaries. So we skipped around a bit, from some show on parasites, to another on weird animals. We watched Ghost Hunters for a while, but even that is a bit much for us. Channels kept on flicking past, but there didn't seem like there was much on. I was getting bored, and I'm sure Kelly was too. She curled up on the couch and rested lazily on her arm as she clicked the remote. My desire rose momentarily again as I glanced down at her curled form. Her ass was protruding towards me and straining against the fabric of her leggings. I gave in a bit, let the feelings return, but quickly recovered and turned my mind to other thoughts. I got a bit impatient for Kelly to choose a channel, and told her so. She told me to calm down. I needed her to choose something though, to help distract me from my thoughts. I sat anxiously, tapping my foot while she would rest on one channel for a second, and then change it to the next thing, until finally she settled on a show. "Hm. This looks interesting," she said. I wish I could have breathed a sigh of relief, but the show she had landed on was anything but helpful. I looked at her sheepishly, half hiding a plea on my face. "What? You prude. It looks interesting!" She laughed and settled back into her seat. The show was called "Laws of Sexual Attraction" or something like that, and it was basically a show about what turns us on. This was not fair; the universe is a cruel, cruel beast. But I gave in, and settled back into my seat. And for a while, things were okay. The documentary was actually pretty interesting, and it wasn't too sexual at first, but of course it didn't last. Eventually the scientific narrations turned to descriptions of body parts, with images to match. The narrator talked about breasts, and a beautiful woman was shown as an example, many beautiful women actually. And then they went on to walk about asses, and again followed it with images of wonderful butts. Nothing was very explicit, to be honest, but it was all very suggestive, and in my current state, I was perhaps overly sensitive. As they showed these scenes and talked about what turns us on, I couldn't help but look over at Kelly. She was still sitting There, curled up on the couch, ass out in those beautiful leggings. I gave in again, and for a little longer this time. I locked my eyes on her ass, and imagined it nude again. I was worried she'd see me and glanced back up to her face, but she seemed enthralled in the show. I began to wonder if she was getting turned on be it as well. Talking about scent, interspersed with scenes of sex...Talking about arousal--erections and wetness...the scent... The show went on for ages, driving me crazy and captivating Kelly. And then it ended. It was late, and I had had quite enough sexual stimulus for the night, so I told Kelly I was heading to bed. She clicked the TV off, and said she'd join me. Kelly asked if she could sleep in my room. I said sure, despite my uneasiness about being alone in a bed with the new object of my desires. This on any other day was not an unusual occurrence. I suppose, it was becoming more unusual as we grew older, but was definitely not unheard of. Kelly and I were close, and often, whenever we stayed up late together, we'd just end up crashing in whosever room we ended up in. It had always felt innocent, but now I couldn't say that. I couldn't help but think of Kelly's warmth, her soft ass, and perky breasts lying next to me. Could anything happen? The moment I thought this, my troubles were mitigated. The notion was so absurd that anything could happen that it helped me to calm down. Still, I lay far to one side of the bed when I got in, trying to keep my distance. Kelly grabbed a shirt from my dresser, a big one that I only used for pajamas. "Can I wear this?" she asked. "Of course." (She always did) She slipped it on over her day clothes, and then slipped her arms inside, using the bigger shirt as a curtain as she removed the clothes underneath. I couldn't stop myself from watching as she did so. Her blue shirt was the first to go. It dropped to the floor from under the shirt, as Kelly's arms wriggled underneath. And then there was a "click" and some more wriggling, before a pink Victoria's Secret bra followed. Kelly's breasts hung free under the shirt, and I was getting hard. She popped her arms back out of the sleeves and reached under her "dress" for the final article. My heart was beating with anticipation as she hooked her hands around the waist of her leggings and slowly brought the fabric down her torso, to her waist, and then below it. The fabric gathered around her hands as the tights were lowered. It was so slow, and almost sensual, the way the soft skin of her legs was exposed inch by inch. When the leggings were on the floor, she stepped out of them and walked to the bed. The shirt seemed smaller on her than it had before. It was still enough to cover her up, but only just. It draped down no more than a couple of inches below the line of her ass. I could see nearly the entirety of her legs. They were beautiful. Without the bra, I could make out the shape of her breasts under the shirt. They were not small, but proportional to her slim body, and perky. Her nipples poked through the fabric slightly. She stopped by her phone, which was charging on the floor, to check for any last texts before climbing into bed. And she bent down. Like I said, the shirt was short, and as she did, the bottom of her bottom became visible. My eyes locked on her and all my desires, which had been there, but being kept at bay, surged back with a loud mental pronunciation: "fuck.," I thought. Kelly's ass was perfect. I knew this from the leggings already, they didn't hide much, but the tanned skin of each globe, and the shape perfectly shown in flesh was too much. For a moment I thought she wasn't wearing underwear, but as she leaned over to the phone I could see the thin strip of fabric emerging from her cheeks. This only made things worse. As much as I would have loved to see her naked bum, and perhaps a peak at her pussy just below, the thong brought back memories of her panties. I had been repressing them until then, and with such a sight, I couldn't help it. I wanted my sister. My gaze was broken as she stood back up and walked to the bed. She got in, and lay a little closer to me than I was hoping, but it was okay. Our bodies weren't touching, as long as our bodies weren't touching, I would be fine. I turned on my side to hide the erection that she had given me and reached for the lamp. "Goodnight," I said, and she responded in kind. I flipped the switch, but was unable to sleep. I laid awake for what seemed like hours, horny as I had ever been, imagining the beautiful woman who lay next to me. Her breathing kept me awake, even it reminded me of her beauty, and I struggled to not touch myself, but I didn't. Perhaps I should have. I stayed awake for what seemed like hours, but eventually I dozed off and slept soundly until early morning when I woke up. The sun was shining directly in through the window; it must have still been early. It glared in my eyes and I took a moment to gather my surroundings. My mind was foggy and new, forgetting about the previous day's events, until my surroundings came into focus. I was warm, and too comfortable. It wasn't my own warmth. Pressed against me was my sister Kelly. We were spooning. I panicked as I realized the extent of the situation. Her body was curled up next to mine, asleep. My arm was around her--and resting on her breast. As my mind began to understand the sensations my body was receiving I realized the worst, and the best, throbbing between my legs. My cock was hard, very hard, and it was pressed against my sister's ass. I froze, not knowing what to do. I wanted to roll over, to turn away, somehow to get to my own side of the bed without her waking up, but I couldn't. I just sat there, enthralled. My heart was racing, but I couldn't help but notice her warmth, or the softness under my hand that rested limply on her chest. I couldn't stop myself from feeling the crevasse of her ass that enveloped my cock. I tried to breathe normally, but this just led to another sensation. Wafting up from under the blanket was the musky scent of arousal. I recognized it immediately from the day before. It was the same as that on my sister's thong, but more powerful, stronger and more carnal. Was Kelly turned on? It was wonderful, and I was lost. I didn't dare move for fear of waking her up, I just laid and enjoyed the embrace. Then Kelly's breathing shifted. It was no longer the slow and steady breathing of someone in slumber, it was conscious and awake. My panic returned. What the hell was I supposed to do? Kelly was awake. I could tell she was awake, but she pretended to sleep. I did the same, trying to come up with my next move. Maybe she would fall back asleep, I hoped. She didn't. We lay there motionless for ages. I kept waiting for my dick to deflate, but it wouldn't. How could it in such a situation? In fact, it seemed to take over. My desires decided my next move, in spite of my panicking brain. I moved, barely, not quite a thrust, but a wiggle, just enough to send shivers down my spine as I felt Kelly's ass shift over my dick. As I did it, I felt the fear return and waited for her to jump up and scream at me, but she didn't. She breathed slightly, and then we sat for another minute. Should I do it again? The question played in my mind over and over until my dick took over again. I did the same motion, slightly pressing myself against my sister. Again, she didn't resist, but she did respond. She inhaled deeper than normal, and pressed back against me. Her move was subtle too, but more than enough to make my dick throb against her. I pushed back. I was less subtle this time, though it still couldn't be called a thrust, and she did the same. Her breathing was heavy now. We continued this pattern of push and reciprocation for a seemingly long time, slowly building up pressure until we were gyrating rhythmically. My pushes became thrusts, and Kelly's breathing increased with each one. My cock had nestled itself firmly between her ass cheeks and when she pushed back they would envelop me, and massage my cock. It was warm under the blankets, and we were both getting pretty worked up. Kelly had began to sweat, this acted as lubricant for my cock as I slid up and down her perfect ass. We continued to grind against each other, dry humping in my bed, though neither of us acknowledged the action, or even the fact that we were awake. I thought that if I stopped now, I could pass it off as some sleep movement. But it felt so good, there was no way I would have been able to. Instead, I went further. I took my hand, which was resting limply against her bosom, and squeezed, grasping the mound of her breast, gently but firmly. I was worried that such a conscious action would ruin the rouse of slumber, but Kelly let out a sigh of pleasure. She pressed her ass more firmly against me, and I sighed too. Like her ass, Kelly's breasts were perfect. Though it was under her shirt, I could feel the perfection of it. Her mound was just enough to be a large handful, and was comfortable to grasp, but kept its sensual softness. And her nipples were pert. I felt the petite nub standing through the fabric against my palm. I massaged it, sensually, which elicited more sighs from Kelly, and as I continued they progressed into moans. I felt like I had to proceed, but was scared to do so. I had already pushed it too far. Anything further and the pathetic act of "slumber" was obliterated. But it already was, really. So I moved my hand from her breast and pushed it down the length of her torso. Her skin was so soft everywhere, and the sensation of it made my cock pulse. Kelly too seemed to enjoy the sensation, as she moaned harder as my hand drifted. I rested it on her leg, stroking her inner thigh as I contemplated whether or not I would actually do what I was thinking of doing. Kelly seemed to thrust harder, this time at the air, motioning me to "do it," so I did. I moved my hand between her legs and placed in on her panty-clad sex. Kelly moaned and continued to thrust. I could feel the softness of her lips through the cotton of her panties, and the thin slit that parted them. I pressed my hand into it, and felt her folds and the hard nub of her clit between them. The heat that radiated from her core was unbelievable. And she was wet. The crease of her panties where they nestled into her slit was damp with her arousal. I pressed firmly against her cunny and began to gyrate my hand in rhythm with our thrusts. Kelly squealed and moaned as I did so. I felt like I could cum if I wanted to but I held off. The worries were gone for me, and the movements became natural for both of us, I felt like we would go with it as far as we felt like going. It was so similar to sex. I humped at my sister, and she humped back, as I rubbed her pussy through her panties. Would there be sex? I pulled back in a long thrust that allowed my dick to drop between her legs, so it was now her thighs that were massaging me. Every once in a while my shaft would rub against her pussy and she would squeal. We continued to thrust, and I continued to rub, getting more and more into it, waiting to see if more would happen. It did, but more by accident than anything really. As I continued to rub Kelly, her thong scrunched up and no longer rested flat against her pussy. It was to the side really, and though my fingers were still above the fabric, with every thrust I could feel the naked silky wet folds of my sister's pussy as they grazed against the side of my fingers. It was natural, and we both seemed anxious for the progression. My cock began to brush against her bare pussy, and with each contact we would both shudder. Closer and closer I would get. With each thrust my dick would linger longer against her. My head was wet with her juices and ready to go. Was I going to fuck my sister? With one thrust, my tip nestled against her opening and her lips just barely began to wrap around it- "Kelly? Andrew? Are you awake yet? We've got to go!" Mom shouted from the bottom of the stairs. I jumped, and so did Kelly. We were both out of the bed faster than an Olympic sprinter, and she was out the door without a word. The wakeup call (apparently more than just a literal one), was enough to shake me out of my daze. Guilt came over me once more. I got ready in silence, trying to think of what to say, scared to death that Kelly was going to say something to mom and dad, and dreading the rest of the day. We were going for a hike. This involved hours in a cramped car, and hours more together with my sister who I imagined probably hated me. I mean, she reciprocated the actions, so I couldn't be entirely to blame. But then again I started it, and I let it continue. I was confused and upset, and had to get the day over with. After slipping my shoes on, I took a deep breath and headed down stairs. Kelly was already there, but she didn't look at me. And she did not look happy. She sat on the couch, with her face glued to her phone. Her expression was plain and angry, and made me even more nervous. I went to the kitchen to avoid the situation. My mom offered breakfast, but I refused. My stomach was in knots and eating anything sounded unpleasant. I asked anxiously when we were leaving for the hike. I wanted to get it over with as quickly as possible. I paced around nervously until we were finally ready to go and loaded into the car. Kelly sat up front, thankfully, and I sat directly behind her. We both spent the time ignoring each other on our phones. The hike wasn't terrible. Everybody tends to be a bit solitary on those anyway and the single file path meant I could avoid contact with Kelly even more. Still, I couldn't help myself from looking at her frame as I walked behind her. Her short athletic shorts showed off her legs, and I couldn't keep myself from looking away all the time, though I did feel guilty afterwards. I spent the day eliciting silence and one-word responses from my sister. She only spoke when something my parents said required a response, and even then she avoided eye contact. Her words were cold and without inflection. I believe she was pissed at me. With just another awkward car ride between me and the freedom of my room, I got anxious towards the end of the hike, but again the ride wasn't all that bad. I guess my parents figured we were both moody or something, so they didn't probe or provoke conversation. The silence was nice, if a bit tense. When we were home Kelly and I both raced to our separate rooms and hid. I watched Netflix, read, tried to keep my mind off of yesterday, but I couldn't. I seemed to have fallen into a spiral, and I started remembering the previous night. Images of Kelly's legs on the hike brought back memories of sensations and scents that I never wanted to forget, wished would have never happened, and longed to experience again. Again I went through the routine of trying not to think about her, losing my will and thinking about her again, until I was full on fantasizing again. I almost fucked my sister. I still wanted to. I wanted her more than anything. Just a few more seconds and I believe we would have done it. Would we have? My fantasies won once more...The sensation of Kelly's soft pussy lips, her heat and her wetness through the fabric of her thong defeated me. I went to the bathroom. In my sanctuary once more, I locked the door. The air inside was humid and warm. The mirror was still a bit fogged. I suppose Kelly had just taken a shower. I began to tremble at the thought. Just like the previous day, I cursed myself as I reached for the hamper. Sure enough right on top was a green thong, surely the one she wore yesterday, and apparently all day today. Our parents had gotten us up so quickly, so abruptly and frazzled us so badly that she must not have thought to change. I picked them up and went straight for the gusset this time, opening up the crotch to examine the evidence of her arousal. She definitely had just showered. The crotch was a mess of still-wet girlcum. Her scent rose from it without having to bring them to my nose. The scent was Kelly. It was the scent of her arousal, the scent of last night. I stroked myself while I smelled her from a distance, keeping myself on edge so that when I finally brought her pussy-scented panties to my face I exploded. The memories were too much, and the scent was too great of a reminder, all of the images of Kelly, all of the sensations of her ass and her breasts, her pussy, flooded my mind in one wave of ecstasy as I made another mess of the bathroom. More routine: I felt guilty. "Jesus, this is getting ridiculous," I thought as I cleaned up yet another mess. I had decided that I had to stop. Obviously, I would continue to have urges, and continue to find Kelly attractive, but I would control myself. No more panties, no more late night anything. She was my sister for chrissakes. I had to stop. And I was going to. This didn't feel like a guilt-powered repression, but rather a logical and willful decision. I had admitted my attractions, now I just had to control myself. I could do that. I left the bathroom and went downstairs. Just in time too, it seemed. My parents were just getting ready for dinner. Once more, Kelly and I were silent for most of the meal. She was still upset. The routine kept on again, until mom and dad went up to bed. Kelly and I were left alone again in the TV room. However she did not join me on the couch. She sat on the chair, isolated and distant, but she didn't bolt upstairs, which I took as a good sign. She didn't look my direction once for the first hour after our parents went to bed. It was uncomfortable. And I know she was upset, but this was getting ridiculous, I was getting angry. I was beginning to feel like I was the only one who had done anything last night. I broke the silence. "Okay. Kelly. We need to talk." "Ya think?" She said flatly, sarcastically, not looking up from the TV. "Yes. I do. What's going on?" "What do you mean what's going on? My brother tried to fuck me, that's what's going on!" She retorted, with anger in her voice. "Hey. That's not fair! You cannot pretend that I am the only one to blame here." "Well, you kind of started it...I had to wake up with your boner against my ass." "Kelly that was an accident. I woke up like that!" "Uh huh," she replied sarcastically. "I did. I'm sorry Kelly, but it's the truth." "Well even if it was, I don't think dry humping me afterwards was...and the other stuff." "No. I don't know, I got lost...and you aren't innocent either." Silence. Kelly knew she wasn't innocent. She huffed and stared angrily at the TV. More silence. "Kelly?" "Yeah." "Kelly, we have to work this out. I love you, as a sister. You've been like my best friend for my whole life, and I'm sorry. Shit happened, but it was only one night, one night out of thousands. C'mon. Talk to me." She exhaled and her face relaxed as the tension began to leave her. "Yeah, but it wasn't just one night..." "What do you mean?" I asked, genuinely confused. "I mean..." she paused trying to find the words or the courage to say the words, "things have changed, Andrew." I was still confused, and my face showed it. "We've grown up. You've grown up. And maybe that just means things are different." "Okay. But what do you mean it wasn't only one night." I was worried she knew about the panties... "I mean I've noticed you. You're an attractive dude...objectively speaking...and I can't say I hadn't thought about you before." I was shocked. I stared at Kelly in utter surprise and silence. It was her turn to break it. "What!? Don't pretend it wasn't the same for you. We hit puberty, it's what happens." A smile cracked on my face. "Kel, I did notice you--yesterday." "What?" "Yeah. I swear a thought hadn't crossed my mind until yesterday, but it hit me like a bag of bricks." "Great. So I'm just a pervert." Kelly looked down, ashamed. "No. No you're not. I think I was just in denial. I always knew you were beautiful, but yesterday it really hit home. And like you said, we hit puberty; it's just what happens. It's not because you're my sister or anything, it's just because you're a beautiful...sexy, girl. Hormones, ya know?" "Yeah I guess," she said, only half convinced, "but what do we do about it? We can't have sex. That's messed up... and I don't want to feel guilty every time I touch myself." Kelly's sudden candor surprised me, and aroused me at once as images of her "private time" flooded my mind. Kelly bit her lip and looked me in the eyes, wanting to say something but not being able to. I waited patiently. "Andrew...I've thought about this a lot today. And I can't get it off my mind...last night I mean..er you, really. I mean, I really, really, enjoyed it, but we can't fuck. We can-NOT." "You're right." "And I don't think I can just go around pretending nothing happened...so I was thinking...maybe." She spoke with breaks between every word, trying to squeeze the sentence out, "maybe we could help each other out. No sex, obviously, but just take the edge off. I don't know about you but I could really use that right now." My expression must have worried her as she quickly tried to backtrack, but I assured her that it was not a bad idea. "I could use that too." I smiled at her, allowing myself to shamelessly eye her up and down for the first time. She smiled broadly and laughed, "Good. 'cause I'm fucking horny." I laughed and sprung at the sentence. I was horny too. A moment or two passed and our laughs subsided into a silence, neither of us knowing how to proceed. "Sooo..." "So...I guess we should get naked, right? So we can see each other..." Kelly said, with more anticipation in her voice. "I guess so." I never had a problem being naked in front of other people, but this situation had gotten to me and my heart pounded as I began to remove my shirt. Kelly was nervous too. Her movements were comfortable, but clumsy as she was conscious of the situation. Nevertheless, her shirt was off before mine. I stopped for a moment to admire her as she sat in nothing but athletic shorts and a blue bra. It made her tanned skin stand out and held her breasts perfectly. Breasts I was about to see. With a pop the cups fell loose and with a shrug of her shoulders, it fell into her hands, which caught it with a slight tremor. Kelly was nervous but she wasn't hiding anything. She sat with her chest exposed, perfect perky nipples standing erect. My cock throbbed against my pants. She didn't pause though, she extended her legs and hooked her thumbs under the waist of her shorts. I fumbled with my belt. Her clothes were quicker though, and by the time I had unzipped my pants her shorts were on the floor, exposing the rest of her slender legs. She was wearing a thong again, only this time I could see it in its entirety, from the way it hugged her mound, and ran down between her lips, bearing the slightest impression of their cleft, to it's strand being swallowed by her perfect ass--to the wet spot that appeared on the crotch. She really was horny. "Wow." I broke in, "Kelly you're so beautiful." She smiled nervously and eyed me up and down, waiting for me to follow her in removing my pants. I grabbed the waist of both my pants and underwear and exhaled before pulling them both down in on fell swoop. My cock sprung up and bobbed as the restriction of my clothes was finally removed, and Kelly's eyes darted straight to it and stuck. Her mouth opened slightly in exasperation and admiration. It was her turn to stare. Quickly though, she proceed with her undress and removed her last article of clothing. We both sat admiring each other for moments before we proceeded. Seeing Kelly fully naked like this, I was truly, truly aware of how beautiful my sister was. Her skin was perfect, soft and tan, and her frame was so slender but shapely. Her pussy was bald, two perfectly smooth soft lips rising from the mound of her pelvis, hiding her even softer inner folds. "What now?" I asked. Kelly scooted towards me so that she was no more than a foot and a half away and faced directly at me. She opened her legs, spreading her self in my direction. As she did, I was given a glimpse of the details of her pussy for the first time. Her pink inner lips were delicate and glistened with arousal. It's scent, her scent, wafted towards me from her sex. I savoured it. Without words, she dipped her hand between her legs and lightly circled her clit. Her mouth parted slightly, and she let out a breath filled with pleasure. My hand mirrored hers as I grabbed my shaft and slowly stroked up the length of it. Kelly's eyes, which had ben transfixed on mine followed the movement of my hand and watched intently as I touched myself. The nervousness seemed to dissipate as the actions started to feel natural. She maintained her slightly agape expression as she observed, but her hand froze on her crotch. She just took the sight in for a few more strokes before her clit demanded her attention and her hand began slowly to move once more. I was throbbing in my hand, harder than I think I have ever been, harder than the previous day. Every stroke sent shockwaves through me as I sat across from my naked sister. I inhaled deeply, becoming intoxicated with her scent, my eyes watching her work her sex in an unbroken gaze. I could hear her wetness, as she rubbed her hand between her lips, and I became acutely aware of how badly I wanted to experience her fully, to taste her. Her movement became more rhythmic, her pace increased as she got into the pleasure. Her breath grew deep and labored and I glanced up, following the contours of her body to her face, which now glowed red and wore an exasperated ecstatic expression. "Fuck Andrew. You're so hot," she moaned between gasps. I glued my eyes back on her sex just as she took two fingers and slid them inside herself. A characteristic "squish" emanated from her sopping minge as she did so, followed by a soft moan from her mouth. I began to pump faster as I watched her plunge her fingers in and out of her bald snatch. Fuck. I wanted to taste her pussy. I wanted to taste the sweetness of her juices. I wanted her so badly. She seemed to read my mind as she slid her digits out of her pussy, and lightly caressed her folds before bringing her hand up and displaying her arousal to me. With her hand inches in front of my face I could clearly see her fore and middle fingers stuck together with a filmy coat of her slimy arousal. Her scent was on her hand too, and its overpowering aroma filled my nostrils before I leaned in for a taste. She stiffened her fingers and offered them to me as I opened my mouth for her. I engulfed her fingers with my mouth swirled my tongue eagerly around them, tasting the tangy sweetness of my sister's pussy for the first time. I sucked and tongued her fingers as she withdrew them from my mouth, slowly, savouring every drop of her essence. She giggled as she did and brought them to her lips, grinning coyly like a schoolgirl. "That felt really good," she said. I smiled back, "you taste really good." From her smile, my eyes were drawn back down her body to her pussy. A drip of her juice had crawled out of her opening and down her ass cheek, and I wished I could drop down and lick it, but I held back. I did take action though; Kelly had led up until this point and it was my turn. I removed my hand, which had been stroking my cock on autopilot and brought it cautiously closer to Kelly's sex. She responded by spreading her legs slightly, so I continued. Inches away from her slit, I could feel the heat radiating from her core: the preview to the warmth of her silky folds. When my hand finally met her slick pussy, her lips enveloped the side of my forefinger as I slid up the length of her sex to her clit. Kelly moaned an "oh my god" and shuddered at my touch. Her legs opened wider as I circled her clit, sliding effortlessly over her button, aided by her wetness. She moaned again, but louder. "Shhhh!" I managed to voice, trying to remind Kelly that our parents were still in the house, even if they were asleep. She bit her lip, which stifled her sounds into high-pitched staccato grunts. She ground her pussy against me. Her hips humped at my hand, lifting her perfect little ass off of the floor at the peak of each rotation. She continued to grunt between breaths. She was lost in the pleasure. Now I would make her melt. With one smooth motion, I slid my hand down from her clit, dipping slightly, and parting the folds at her opening. With her wetness easing the way, I pushed into her. The grunts couldn't hold back the pleasure of this new sensation and a full volume moan broke through her lips. Her pussy was tight--soft, wet, and steaming--but tight. She clenched around my fingers. I kept them buried to the knuckle momentarily, trying to experience the wonderful sensations of the inside of my sister's vagina. Then I drew my now cum coated fingers out slowly, watching how her lips clasped on to me as I did, before dipping back into her center again. With each movement of my fingers Kelly moaned, and she tried to stifle it, but she could not hold back. "Shhh," I said again, though I knew it was futile. Kelly continued to express her pleasure vocally as she slammed her pussy against my fingers. As much as I wanted to hear her moans, I retained my apprehension about getting caught. In the living room, where we were, there was nowhere to go if someone were to come down. Our parents rarely did, but I did not want to take the chance. At this hyper-aroused point, I was more concerned about not being able to finish than explaining the incestuous touching to my parents. I pleaded with my expression to Kelly, but like my "shhing" it was hopeless. She continued to moan, louder with each thrust of my hand. And with her pussy coating my fingers in cum, and her wanton gyrating reciprocation, there was no way I was going to stop, but something had to be done. I leaned in towards Kelly, bringing my face close to hers. I could feel her exasperated moans on my face as I pressed my lips to hers. Her mouth was open when I kissed her, but she moved her lips with mine in reciprocation. A new moan of fulfillment passed from her lips with the kiss. It was apparently exactly what she wanted. And it muffled her moans as she moaned into my mouth as I continued to finger-fuck her. I was worried the kiss was going too far, but her tongue met mine eagerly and we made out with hunger. I continued to pump her pussy with my hand, and she continued to moan, growing closer to her inevitable orgasm, as she reached her hand around my back, pulling me closer to her. She was forceful and pulled us both down so that I lay on my knees between her legs. My hand had slipped out of her pussy in the process and I brought it up to knead her breast. My fingers were soaked in her cum and I smelled the strongness of her scent once more. She moaned at the touch of my lubed hand on her breast, but her sex was left wanting, with her hips gyrating in air, searching for fulfillment. She pulled me down again until I felt her breasts against my chest and the soft skin of her torso meeting mine. Her movements and mine were both instinctual. Yes, she pulled me to her, but it was natural, it was the progression. Her hips continued to hump, and with me between her legs our pelvises met. The instinctual movements had landed my cock on her pelvis, and, instinctually, my hips began to move to her rhythm. With one thrust, I slipped so that my shaft was nestled between her lips. Renewed passion, vigor, and moans returned to our escapade as our sexes touched. Her wet folds enveloped my shaft and my I slid over her clit. "Fuck!" I exclaimed, breaking our mouths' embrace for the first time. "That feels so good!" Kelly followed, almost as if she were completing my sentence. We looked in each other's eyes as we continued to grind against each other, and had a collective realization. Kelly voiced it: "We're not going to fuck are we?" She had genuine concern in her voice, though she continued to slide her pussy on me. "No. We can't. You're my sister," I said in broken sentences between breaths, "we said we'd help each other out, that's all we'll do." Kelly bit her lip and nodded, before returning her concentration to the sensation between her legs. She started moaning again too, but I did not restrain her this time. Like her, I was gone with the pleasure. Her wetness allowed my cock to slide perfectly between her lips, and with each thrust my whole length was massaged by the whole length of her cunt. Then one thrust went too far, and for a brief moment my tip caught in the dip of her opening. We both pulled back reflexively, returning to our rhythm. "Fuck," Kelly moaned, "we almost did it." "I know," I replied, and we kissed in a unitary expression of "relief" that we didn't. And then it happened again...a bit deeper, and for a bit longer. Kelly moaned. She thrust her hips, almost as if she was trying to pull me further in, but I retreated and we continued to hump. It was mere moments before my cock dipped down again, and in the rhythm, I slipped in slightly once more...Again, this time was a bit deeper, and a bit longer. About half of my length was inside her for that moment. Like before, I retreated again, but rather than pulling out and returning to our rhythm, I drew myself until my tip was just nestled against her opening, and pushed. My cock slid into my sister until her pelvis pressed against mine, and she moaned, unrestrained, unabashed moans. The sensation was unreal. Her sex was tight, wet, and hot, her silky ridges sent indescribable pleasure through me with each movement. It was instinctual. It felt right--it was right. I withdrew and pushed, slowly thrusting into my sister, once, twice, three times before we came to our senses. After the third time I stopped, and so did Kelly. I looked her in the eyes, with my cock buried to the hilt in her pussy. "You're inside me," Kelly stated in her winded, pleased, voice. "Mhm." I nodded, almost ashamed, before beginning to pull out, but Kelly stopped me. She grabbed my arms and held me in her, biting her lip and shaking her head. "Don't." I froze, and stared into her eyes. She looked back with longing, still clutching onto my arms. I was going to fuck my sister--I was fucking my sister. I leaned down and kissed her, with passion, and with love, and I slowly began to thrust. My cock had barely begun to move when her moans returned. She sounded into my mouth as I slowly pumped my cock in and out of her pussy. I moved slowly at first, enjoying the sensual feeling of my sister's sex, and her hips joined the rhythm as she enjoyed the same. And we kissed passionately, exploring each other's mouths between hard breaths and moans. And the pace quickened. Our tempo rose to match our desires, and I truly began to fuck my sister. Eventually my torso was contracting forcefully in beat, slamming my prick repeatedly into her cunt. The familiar noises of wet pussy sounded rhythmically, punctuated by the slap of my dick bottoming out when my pelvis hit hers. This punctuation and the increased rhythm drove Kelly wild. She screamed into my mouth and her hips bucked wildly. Her thighs began to contract, and her feet flailed uncontrollably as she grew closer and closer to her orgasm. I was growing close too. Her pussy joined in uncontrolled contractions, urging my dick on to spill its load. With each withdrawal the walls of her sex grabbed and massaged the length of me, bring me to the edge. Though I knew I would not last much longer, I kept up the pace. I wanted to feel Kelly cum. She was so close, the only thing I could do was to fuck her harder. I changed the angle of my thrusts, lifting my ass with each stroke to excentuate the length of each insertion. I slid the entirety of my cock from her sopping slit until the tip just rested at her opening, then drove the whole length back in with force until my pelvis rammed her clit. Kelly broke our kiss and screamed in the open. It was loud, but I couldn't care less. Her moans drove me to some carnal insanity. I did it again, making sure she felt every millimeter of my dick, while I experienced every millimeter of her. Repeatedly I slid my entire length in and out of her, feeling my seed boil up with each beat. Kelly screamed every time I pushed into her, until the pleasure won and an rapturous wave of orgasm overcame her. Her soles slid along the floor rhythmically as her thighs contracted in orgasmic convulsions. Her pussy clenched down on me, hard, and milked me as I came over the edge too. I shook as I exploded, shooting masses of my hot cum deep inside my sister. She looked at me as we came together, mouth wide as she moaned. My orgasm seemed to last for ages. With every orgasmic contraction, I would unload more seed, truly filling up my sister. Eventually, the tide receded, and we both collapsed in blissful exhaustion. We lay, locked together, hot, sweaty, breathing heavily, and reeking of sex for several moments, basking in the wonderful awareness of our carnal unity. I was still hard, and Kelly's pussy refused to relinquish me, and I didn't want her too. I stayed inside her until we had both caught our breath and settled into relaxation. Reality was there, and we had to face it sooner or later. Slowly, I pulled out my overly sensitive dick, very nearly cumming again with the movement, and kneeled between my sister's legs. Her pussy was puffy and pink, gaping and wet--thoroughly fucked. We both looked down at the mess as my cum began to drip out of her cunt. A glob of goo seeped from her opening down between the cheeks of her ass. The sight was hot, and only got hotter as Kelly scooped it up with her middle finger and brought it too her mouth, tasting the mixture of our sex. I grinned, and she laughed, "what! You got to taste me." As reality continued to return to me, however, my smile faded, and Kelly's followed. "Kelly.." "I know. I'm sorry about how I reacted earlier. It won't happen again though, I promise." I gave a half nod, still feeling unsure about having slept with my sister. "So what now?" I asked. Kelly looked at me, and eyed me up and down before replying. "Well...I can't deny that I feel a little conflicted...but my desires are not going to just vanish...and that just felt, I don't know, perfect." I nodded again. "And I mean, there's no way I would be able to help myself even if I wanted to. And I don't." "So, we keep 'helping each other out'?" "Yes!" We both smiled enthusiastically, and I embraced my sister, filled with joy and anticipation of things to come. "Can I sleep in your room again tonight?" Kelly asked. I grabbed her hand and helped her up. We gathered our clothes and headed upstairs. I walked behind Kelly, openly admiring her ass as her hips swayed with each step. I slapped it lightly and grinned as she jumped and giggled at the touch. There was no hesitation this time in my room. We both dropped our clothes, still covered--and filled--with the mess of sex ,and climbed into the middle of the bed. Kelly was on her side and I rapped my arm around her, pulling her against me until her body nested into mine. I laid my hand on her breast and cupped the warm mound fully, and she pressed her bum against me. I began to grow hard. It was going to be a good night. pics---->> http://bit.ly/1D1q3qp
