She of course 'just happened' to mention that my twenty year old younger sister Elizabeth would be there too and it had been such a long time since the whole family had been together. I'm sure she did miss us but I think the invitation really had more to do with her wanting to meet Rachel, who I had been seeing for just over six months but had never met my parents. Rachel said she was okay with it so I shrugged and told mom we would be there. The weather actually turned out to be pretty nice while we were there and we spent a lot of time outside. Rachel hit it off quite well with both my parents and my sister but still stuck fairly close to me most of the time. One afternoon were sitting out next to the pool sipping on drinks when she made a comment that almost made me spit mine back out. "You know, your sister kinda has a nice ass," she said. A quick glance around the area confirmed that no one else was close enough to hear; dad was still at the barbecue, mom was inside somewhere and Liz had just surfaced from diving into the pool. Presumably Rachel had taken the opportunity to check her out before she had jumped in. One thing I had never figured out about Rachel was whether or not she was actually into girls. I'm pretty sure she just liked teasing me, and let's face it there are significantly worse ways to be teased, but every now and then she would say something that left me unsure. Like remarking on my sister's ass for instance. "What the hell Rachel?" I hissed. She broke out into that weird smile she always gives me when she messes with me and tilted her head a little. "What's the matter? You know I'm right." I shook my head but she persisted. "You gonna tell me you never once checked her out? Not once?" "Okay, maybe a couple times," I relented hoping it would satisfy her. "But she's my baby sister, you don't think about that kind of thing y'know?" "I know, I'm just teasing. You still love me right?" Rachel whipped out her puppy dog eyes on me and I sighed dramatically. "You know I do, even if I don't understand why sometimes." "It's 'cause I'm hot and I put up with you," she explained patiently. "Oh yeah, that's it." I smiled and leaned in for her apology kiss before settling back into my chair. Only a few minutes afterward Elizabeth pulled herself out of the pool and I shook my head slightly to myself. I didn't understand the idea of swimming for a couple minutes at a time then taking a break but she seemed to enjoy it so who was I to say anything. Despite my protests I found my attention drawn to my sister's body as she picked up her towel and dried off. It's not like it was my fault she looked good in a swimsuit was it? Realizing Rachel would be watching me I turned back to her to find her smirking knowingly at me. "Whatever, you're just jealous you don't have a hot sister," I said. I closed my eyes and leaned back hoping to avoid any further teasing but was actually surprised by her response. "I kinda am actually," Rachel said wistfully. "I never had siblings growing up, you're lucky." She seemed completely serious which, while not unheard of, did throw me off balance a little. "Well it's not always that great really," I said. "I mean don't get me wrong I love my sister, but I've heard horror stories from other people and even me and Liz don't always get along." "Always wanted a big brother," she said, completely ignoring me. "I used to have a friend who lived a few houses down the road who had an older brother. I think he was probably my first crush. Bit weird crushing on an older brother figure I guess, but what can you do?" She looked at me with her head tilted slightly. "You think Liz ever thought about you that way? Maybe we could compare notes." And we were back to the teasing, that didn't take long. I was saved from a conversation I was unprepared to deal with by my sister who came over to join us with her towel draped over one shoulder. "Hey, what you guys talking about?" Elizabeth asked. "Siblings," I said. "Rach thinks you're lucky for having a brother." "Aw, of course I'm lucky. I wuvs my big bwuvver," she said and gave me a big hug. I noticed immediately that although she had towelled off, her suit was still wet. Her top left a big damp spot on my shirt causing both girls to giggle as Liz sat down on the chair beside us. I didn't really care about the shirt but I was somewhat concerned about the hug. My sister had pressed her boobs into my chest pretty firmly in order to get me as wet as possible and I couldn't help but notice how nice they felt against me; just like if they had belonged to any other girl. I wished Rachel hadn't said anything because now that I had started thinking about Liz I was finding it difficult to get it out of my head. It would have been nice if there was some mechanism in my brain that would leave me incapable of viewing my sister as anything other than my sister. All I really had was a half-assed self-inflicted mental slap on the wrist anytime my thoughts turned inappropriate. Fortunately with Rachel and Elizabeth getting along the way they were they could mostly carry the conversation themselves and leave me to my own devices. The only problem was if one of them decided to pick on me the other tended to back them up. Mostly I didn't worry about that so much but Rachel's comments regarding my sister had hit uncomfortably close to home and those kinds of thoughts were not ones I wanted anyone else to know. **** I made it to bedtime without any further mishaps much to my relief. Rachel and I were sharing my old room which was right next to Elizabeth's. When I entered the room after going to the bathroom I found Rachel sitting on the bed in her nightshirt waiting for me. Oddly she had her hair up in a ponytail which was not something she usually did just before bedtime. "Hey big brother," she greeted me cheerfully. "Uh, what?" "I'm glad you're back, I miss you so much when you're away," she continued. "Do you mind if I stay with you for a while? We hardly get a chance to be alone anymore." So Rachel was pretending to be my little sister now, what the hell was that about? Unless our earlier conversation hadn't been quite as much about teasing me as I thought. I recalled her mentioning a brother fantasy earlier and despite myself I felt a small shiver run up my spine. "Yeah, sure," I croaked. She smiled and scooted over on the bed to make room for me. She lay on her side facing away from me and I instinctively spooned up against her and wrapped my arm around her waist. "Mmm, you're so warm," Rachel cooed. "I wish we could sleep together every night big brother." There was a subtle emphasis on her final two words as though she was trying to make sure I was going to play along. "I bet you do, but I don't think that's all you want." "What do you mean?" she asked, feigning innocence. "I mean you jump in my bed with hardly any clothes on, you're being bad aren't you little sister?" Emulating Rachel I stressed the last two words of my question. "Nuh-uh, I wouldn't do that," she protested, shaking her head. "Really? I think you would. Are you even wearing panties under your shirt?" I was gambling a little on that one, but knowing Rachel I didn't think there was much risk of being wrong. When she didn't answer me I knew I guessed correctly. "Well, aren't you going to answer? Do I need to check for myself?" I asked. Rachel continued to shake her head into the pillow but made no move to stop me as I slid my hand up her bare leg under her shirt. I took my time running my fingers lightly over her thigh and I felt her legs part slightly for me. "Just what I thought little sister, you're being a bad girl aren't you?" "I'm sorry, I can't help that I'm like that. Please don't tell daddy," she begged. I had to admit this new game was really turning me on. If I had known this was what Rachel was working toward when she had been teasing me earlier I probably would have even played along a little. "Don't worry baby," I whispered in her ear. "You may be a bad little girl, but you're my bad little girl. I wouldn't let anything happen to you." "Promise?" "I promise," I assured her. "I love my little sister and I'm going to take care of her always." Rachel squealed softly and squirmed against me as my fingers ran gently over her pussy. She usually kept it nicely trimmed but as I explored further I realized that she had shaved her it completely bare. I had no idea when she had found time to do that but I didn't really care either, I was too busy enjoying the feeling of her smooth cunt. "Mmm, you feel so good down there. So wet," I added as I slid a finger between her pussy lips. "You like it? I didn't know if it would be okay," she told me nervously. God Rachel was playing her part well. "I love it baby. And it's all mine isn't it?" "Yes," she hissed as I slid a second finger inside her. "It's all yours, anytime you want. No one else will... ooh," she trailed off as I found her clit with my thumb. Rachel moaned appreciatively as my experienced hand worked her toward a quick orgasm. I was beginning to get worried about the level of noise she was making but there wasn't much I could do about it. My free hand was trapped between us and there was no way I was going to stop masturbating her while she was on the verge of cumming; I knew better than that. Before long I felt the familiar tensing of her muscles as she came on my fingers and I smiled to myself. I was getting pretty good at that. When her moaning subsided and her body relaxed I carefully pulled my hand away from her pussy. Before I could move them far she grabbed them and pulled them to her mouth. "I made a mess didn't I big brother? Don't worry, I'll clean you up," she said. First she licked one finger up and down then the other before sucking them both into her mouth. I groaned as she cleaned her own juices off of me and pressed my body in tighter against her. "Hey, who's being bad now?" Rachel giggled after releasing my hand. My cock was poking into her butt pretty firmly and I had no doubt that was what she was referring to. "Don't worry, your sister will take care of you," she continued as she slid down to my waist. She pulled down my shorts and gasped as my erection sprung free. Her hand was on it almost instantly and she looked up at me mischievously. "It's so big," she breathed. "I don't know if it will all fit in my mouth." I knew for a fact that Rachel could get my entire cock in her mouth without much difficulty, but for the purposes of the game I said nothing. She worked it in clumsily, pulling back every so often to give it small licks up and down the shaft with the tip of her tongue. Eventually I caught on that she had no intention of actually giving me a proper blowjob. "Are you having trouble baby?" I asked. "I know somewhere it might fit easier." Her eyes widened in a good approximation of shock as she sat up. "We can't do that!" she exclaimed. "That's..." "Bad? I know. You're my bad little girl aren't you?" She smiled happily at me before biting her lip and raising herself up so her hips were poised above mine. Her pussy was so close to my cock I could almost feel the heat coming from it and I had to fight the urge to pull her down onto me. "Are you sure?" she asked nervously. "I'm sure. I love you and I want you, it can be our secret." Rachel looked away from me for a second and I think she actually managed a real blush for a moment. "Okay, I'll do it for you big brother. Anything you want," she said, the last part barely a whisper. She had the bottom of her shirt pulled up around her waist giving me an unobstructed view as she sank down onto my cock. I had been inside her many times before but I felt this time I wouldn't last as long as usual, not with how turned on I was. This time she didn't pretend to have any problems and soon my erection was completely buried inside her. "Ooh," she cooed. "I'm so full, feels so good." Rachel started rocking on top of me, letting my cock slide out a few inches before disappearing back inside her. I tugged at the bottom of her shirt and without hesitation she pulled it over her head. She leaned forward and placed her hands on the bed to either side of me as she increased her pace. Her eyes had a wild look to them and I could tell she was losing focus on our game. "I'm gonna cum soon baby," I whispered as I ran my hand up her naked thigh to her ass and back down her leg. She nodded in acknowledgement but said nothing. I felt my first jets of cum spurt into her pussy moments later and saw a feral smile cross her face briefly before she slowed her movements and finally climbed off me. "How was that big brother," she murmured as she stretched out beside me on the bed. "That was good baby, so good." I enfolded Rachel in my arms and kissed her gently on the top of her head before settling in comfortably. "That was kinda hot," she whispered, breaking the silence. "Yeah, it was," I agreed. "I just hope Liz didn't hear it." "Are you kidding? She's like three feet away through a little-bitty wall, she heard everything." "Whatever," I said dismissively as I failed to hold back a yawn. I knew she was just teasing again, but at the same time I worried she might be right. **** It didn't take long the next morning before I began to suspect that my sister had indeed heard more of our role-playing than I would have liked. All through breakfast I felt as though she was looking at me funny and she seemed quieter than normal. I had to remind myself that I could just be imagining things and the best thing to do was just act normal until I had something more definite to go on. Rachel of course didn't seem the least bit bothered by the possibility that we had been overheard. Then again, it wasn't her sister we might have weirded out. I was glad she was still her usual talkative self though because between her and mom the rest of us hardly needed to say anything. After breakfast I retreated to the back yard to try and get at least a little time on my own to think. I had pretty much decided that I wasn't too bothered by the shared fantasy Rachel and I had acted out the previous night. Much as I had never liked to think about that sort of thing, the fact was that it was only a fantasy and wasn't hurting anyone. Besides, even though it was a little sick I could hardly deny to myself that I had enjoyed it. Mainly I just really, really hoped that Elizabeth didn't know what we had been up to. That could be awkward. "Hey, what ya doing?" called Rachel. "Nothing. Thinking, you know," I replied as she came over to sit beside me. "About last night still? Me too," she purred. "Yeah, but not like that," I said, rolling my eyes. "And they say it's guys who only think about sex." "Speaking of sex, your mom just went for a walk and your dad's already gone to work...." She reached her hand out to cup my crotch through my shorts and I had to quickly pull it off. It hadn't escaped me that she had purposefully failed to mention my sister. "And what about Liz?" I asked. "Oh, I dunno. Inside somewhere I guess," Rachel replied with a shrug. "Come on, what's the big deal? She already got to listen to us fucking last night." "You don't know that," I argued unconvincingly. "Puh-wese big brother," she pouted. "I want to try with my mouth again, I think I can do better this time." I sucked in my breath involuntarily, her little girl voice was getting better and I had always had a difficult time saying no to her as it was. Seeing my resistance crumbling Rachel knelt in front of me and worked my slowly hardening cock from my shorts. She happily licked and stroked my growing erection until it achieved its full length before wrapping her lips around taking it her mouth. I groaned and leaned back in my chair as I watched her, my fear of getting caught being replaced gradually by pleasure. Rachel could give an excellent blowjob when she wanted to, and she was doing just that. My earlier fear turned out to be well founded however as I noticed movement in the corner of my eye and whipped my head around toward the house just in time to see Elizabeth closing the door behind her. She clearly didn't catch on to what was happening immediately as she took a few steps toward us before stopping short. Rachel, sensing the sudden tensing of my muscles, paused long enough to look up and see what was going on. "Oh, hey Liz," she called cheerfully before lowering her mouth back over my cock. I was beginning to understand what a deer caught in the headlights feels; I knew something was happening but I wasn't entirely certain what it was or how I should react. Elizabeth looked at me curiously and took a few hesitant steps closer before locking gazes with me briefly. When I didn't say anything right away she shrugged and sat down on a nearby chair, pulling her legs up to her chest and resting her head on her knee as she watched us. Rachel, ignoring the silent exchange between my sister and I, had been working steadily on my cock the whole time. Despite my apprehensions at having Elizabeth present her mouth was having the desired effect on me and I was seconds away from orgasm. She dutifully swallowed my cum as it shot onto her waiting tongue then stood up with a contented smile. "All gone," she chirped. I accepted a quick kiss before she headed back inside and left me alone with Elizabeth. Belatedly I remembered to tuck my cock back into my shorts and readjust myself, not daring to look at my sister as I did. "I'm sorry 'bout that," I mumbled eventually. "Whatever, I could have gone back inside," Elizabeth replied. "Besides, I'm pretty sure your girlfriend's the one getting you in trouble rather than the other way round." At the neutrality in her voice I risked a glance at my sister. She didn't look upset, but then I supposed if she was upset she most likely would not still be sitting outside with me. "I'm kind of a sick puppy I guess," she said softly. "I know I shouldn't watch but when I saw you two, you know, doing stuff..." she shrugged. "But then, I'm not the only one who's a little messed up am I?" At that I knew for certain she had heard Rachel and me. It was almost a let down after all the worrying I had done to find out that she didn't really seem to care that much, but on the other hand it was certainly better than the alternative. "You don't mind?" I asked to be sure. "Not really, it's not like I haven't had twisted fantasies of my own over the years. Although I do try to be a little more discreet about them," she added with a smirk. "Yeah yeah, whatever. It's not like I planned on... any of this," I said, waving my hands in an attempt to make my point more clear. "I know, I'm just teasing. If it makes you feel any better about being a weirdo, I got off last night listening to you two. You're not the only one." After her last statement Elizabeth got up and returned to the house once again leaving me on my own. I don't know that her attempt at reassurance actually helped any, if anything I think it left me even more confused as to where we stood. **** I kept to myself for most of the day even though I understood the danger of leaving the girls alone together. I figured whatever scheming they might get up to against me would be manageable if I could at least get my head straightened out. In the end I may as well have just hung out with them for all the good introspection did me. My thoughts inevitably turned sexual, mostly focused on Rachel with her hair up in a ponytail and that adorably innocent look on her face that she had used when she was pretending to be my little sister. Sometimes though she was replaced by Elizabeth, and as the day went on I was slower and slower to shake her image from my head. Twisted Summer I consoled myself with the thought that nothing seemed to have changed between my sister and me, and that fantasies that stayed firmly in my mind weren't going to hurt anyone. Even if we had thoughts about each other it didn't mean it would go any farther than that. We could still just be a brother and sister who happened to be a little twisted, that's all. At least I thought we could. It wasn't until that night that I discovered that the girls had other plans. I had just finished stripping down to my boxers and was getting ready for bed when Rachel entered the room followed closely by Elizabeth. The first thing I noticed was they were dressed near identically in skirts and matching pink shirts as well as each having pulled their hair up into ponytails. "Hey, what's up?" Rachel greeted me cheerfully. "Um, not much," I answered slowly. Warning sirens were going off in my head and I tried desperately to come up with a reason to quickly leave the room. It wouldn't have done any good of course, not when I would have to return at some point to go to sleep, but I wasn't thinking entirely rationally. "Good, 'cause me and Liz had an idea that we need you for," Rachel continued, nodding her head toward my sister. "We were thinking that it's not really fair that she had to listen to us last night and didn't even get to watch." "What?" I responded stupidly. Rachel just stared at me expectantly, knowing full well that I understood what she was getting at. "Rach, that's not... we can't...." My attempts at forming an argument were failing pretty hard so instead I turned to my sister. "Liz, what's going on?" "I told you I'm a little twisted didn't I?" Elizabeth shrugged. "Yeah but still, I mean...." "Oh come on you big baby," Rachel interrupted. "She's just going to watch, it's not the end of the world. I promise I can make it worth your while," she added. I resisted the urge to ask how she was going to do that, but it didn't really matter. Not waiting for my response Rachel had taken Elizabeth's hand and pulled her gently closer. There was a moment of silent communication between the girls as they stood face to face before Rachel leaned in slowly to kiss my sister. It was only a brief kiss, their lips barely brushed before they separated, but it was followed almost immediately by a longer one. As my sister and girlfriend made out in front of me I could do nothing but stare like an idiot. They were obviously doing it just to get to me but that hardly mattered, it was still working. I was struck suddenly by the thought that dressed identically as they were they probably could actually pass for sisters. I resolved to keep that firmly to myself, they clearly didn't need any help messing with me. Finally they broke apart and turned back to me, both somewhat out of breath but looking quite pleased with themselves. Even without looking down I knew my boxers were tented prominently and that the girls could hardly failed to have noticed. "I still don't believe you like girls," I mumbled. "Whatever," Rachel dismissed me cheerfully. "It gets better too." She looked at Elizabeth and nodded before moving to stand behind me with her arms around my waist. Elizabeth at least now seemed a little bit nervous too which reassured me that she had some hesitation about whatever was going to happen as well. She hesitantly hooked her fingers in the waist of her skirt then, with a look of determination, pulled it down to the floor in one swift movement. I drew a sharp breath as she stood back up wearing only her panties and t-shirt, shifting her weight apprehensively from one foot to the other. "Nice, isn't it?" Rachel whispered in my ear. I closed my eyes and just nodded, not daring to look at my sister as I did. When I reopened them Elizabeth was still in the same position but with a small smile on her face as if she had been waiting for my approval. After giving me few seconds to stare Rachel guided me to the bed and had me lay down. I focused gratefully on the ceiling as she pulled my boxers down since that meant I didn't have to watch Elizabeth's reaction as my erect cock came into view. Once finished with me Rachel immediately began pulling off her own clothes with none of the self-conscious reluctance shown by either my sister or me. Then again, she didn't have a sibling watching her. As soon as she finished stripping Rachel attacked my crotch, sucking and licking with intensity driven no doubt by her wanting to put on a show for my sister. Working up my courage I turned my head to find Elizabeth sitting in the chair by the wall, the only other place in the room to sit besides the bed. Her hand had at some point slid beneath her panties and I found myself insanely wishing she had removed them as well. "See, not so bad," said Rachel, pulling her mouth away from my cock and beginning to reposition herself. No, not so bad. Fucked up certainly, but I couldn't deny that I was enjoying myself. Rachel had moved to straddle my waist and as she began lowering herself I once again admired her perfectly smooth pussy lips. It was a good look on her and I decided I might have to suggest she keep them that way. My attention was temporarily drawn away from the sight of my cock disappearing further inside Rachel's cunt by the sound of Elizabeth's breathing which had become much louder and more ragged in the past few minutes. She had a glazed look in her eyes and her hand was moving frantically under her panties as she watched us. Rachel followed my gaze and smiled. "Guess she likes it too," she said. "Mm-hm," I agreed absently. The sight of my sister masturbating openly combined with the feeling of my girlfriend riding my cock was getting to be too much for me. "Gonna cum Rach," I whispered. "Mmm, good boy," Rachel moaned. "That's it, cum in me right where your sister can watch." I wasn't paying enough attention to know for sure but I think Elizabeth and me must have hit our orgasms at almost the same time. As the last of my cum emptied into Rachel's eager pussy I noticed my sister was leaning back in her chair with a satisfied look on her face. Not having gotten off yet Rachel rolled off me and soon had her fingers buried in her cunt. With my attention drawn to her I didn't even realize Elizabeth had moved until I felt her weight shift the mattress. "What are you doing?" I asked her. "Going to sleep, duh." My sister curled up next to me apparently with no intention of returning to her own bed. Any other time being naked in bed with her would have been incredibly awkward, but given what had just happened I couldn't bring myself to care. Eventually Rachel finished up as well and had the foresight to go turn off the light before settling in beside me across from Elizabeth. From the sounds of their breathing the girls both fell asleep with relatively little trouble. I, however, remained awake for quite some time. Partially because I was enjoying the feeling of having two girls in bed with me, but also because I was worrying about what exactly that meant for my relationship with my sister. **** I was awakened the following morning by Elizabeth getting out of bed. She was obviously trying to move gently to avoid waking Rachel and me but I had been sleeping lightly and even the slight shifting of the mattress was enough to rouse me. "Where you going?" I mumbled, catching the back of her shirt as she attempted to stand. "Gotta pee you jerk," she whispered back, swatting my hand away. I followed her with my eyes as she made her way out to the hallway. She still had on her t-shirt from the night before but as I gazed lower I realized I couldn't see any trace of her panties. My cock twitched beneath the sheets at the thought of her walking through the house completely bottomless but I quickly dismissed it as my simply not being fully awake. "Mmm, that's a nice sight to wake up to," commented Rachel sleepily from behind me. "Sorry, didn't mean to wake you," I said. "S'okay," she replied before falling silent for a moment. "Your sister's still got a nice ass," she said eventually, as if daring me to argue the point again. Silently I agreed with her, having gotten past most of my reservations on the issue, but I refused to answer on principle. Shortly after Elizabeth returned and walked quickly back over to the bed. Not quickly enough that I didn't have time to confirm my earlier suspicion. "Where are your panties?" I managed to ask as she slipped back beneath the covers. "They were too soggy, had to take them off," she replied as if it was no big deal. "They're on the floor somewhere I think." I groaned and closed my eyes as my sister snuggled back up to me. "Goddammit Rach, you're a bad influence on her," I accused. "Yeah, I know." I suspect all three of us would have been content to just lay there for the better part of the morning but the sounds of our parents getting up forced us to move. Probably they wouldn't bother checking on us for quite a while, however the consequences of getting caught were more than I wanted to imagine. For the first little while of the morning I worried that mom or dad would catch on. There was no reason they would of course, but my mind couldn't help playing out various terrifying scenarios anyway. I mused idly that it was a bit of a weird family visit when I spent most of my time trying to avoid one family member or another. Then again, that was probably normal for some people. Dad had to go to work again before too long, which meant one less person to worry about much to my relief. Shortly thereafter Rachel informed me that she and my mother were going out shopping together. I could understand mom wanting some time alone with my girlfriend but I was less clear on Rachel's motivation. I was standing at the window watching them pull out of the driveway when Elizabeth walked up behind me. "Hey Liz," I said. "Mom and Rach just left. I'm kinda surprised you didn't want to go with them." "Enh, I gotta pack. Have to be back for tomorrow you know." Something about the way she answered struck me wrong. I was pretty sure she had actually mentioned leaving early that afternoon so I didn't think she was making that up. Maybe it was just something about the way she said it. I didn't know what else to say so I waited to see if Elizabeth would anything. She also seemed to be waiting for me but eventually gave up with a shrug and turned away. It occurred to me a few minutes later that she might have wanted to talk to me while we had the opportunity to do so uninterrupted. Certainly there was lots to talk about regarding what was going on between us, but I didn't understand why she didn't say anything if that was the case. Still, if there was anything that she needed to discuss it would be better to do it before she left. As she said she would be I found Elizabeth in her room in the middle of throwing her clothes in her bag. She glanced over her shoulder as she heard me approach but said nothing. "Do we need to talk?" I asked bluntly. "What about?" she replied, giving me a curious look. "I dunno. It just seemed like there was something on your mind but I could be wrong. Thought I should at least ask." Elizabeth continued packing for a moment, possibly considering what she wanted to say. "You gonna come down again next summer?" she said finally. "Yeah," I nodded slowly. "I probably could do that, have to talk to Rachel of course. Be nice to see each other a little more often." After I said it I realized that 'seeing each other' now held a somewhat different meaning for us than it used too. "You'd like that would you?" Elizabeth asked with a raised eyebrow. "I would," I stated, determined not to backtrack on my words. "You're going to have a long wait." Her tone was meant to be teasing, but I don't think her heart was really in it. Whatever was going to happen between us I think we both would have liked more time to work it out. I moved behind her and placed my hands on her hips as she finished with the last of her clothing and zipped up her bag. "When did you say you have to go?" I asked. "I planned on getting out a little early, get home around mid-afternoon. Give me some time to myself." Left unspoken, but implied, was the confirmation that she didn't really have to leave for a little while. Not if she didn't want to. I let my hands slip under her shirt but kept them around her waist, caressing the skin just above her waistband. "What are you doing?" Elizabeth demanded. "Just being close to my sister. That's okay isn't it?" "Being a perv more like," she accused. "Not the only one," I countered. My hands were roaming more freely under her shirt, though still not going any further than the soft curve of her tummy. "They'll be gone at least an hour or two," she mused. "Rachel said she'd call if they were going to be back any sooner." "Uh huh, and why would she do that?" Elizabeth turned around to face me, leaving my hands to settle on her back. "So we could get some time alone," she said simply. "So we can talk?" "Come on," she said, rolling her eyes dramatically, "even you're not that slow." "Try me." She stared at me a second, then grabbed my wrists and pulled them down until my hands were cupping her butt. The look on her face was one that promised violence if I continued to pretend innocence. "You sure Liz?" "Completely. Fucking twisted isn't it." Her fingers played with the hem of my shirt, drawing it slowly upward. "Long time 'til next summer though and I'm not that patient," she continued softly. I raised my arms and allowed Elizabeth to pull my shirt off over my head. A bizarre feeling of calm took hold as she began gently kissing my chest, completely the opposite of the urgent sense of wrongness I should have felt. I traced the length of her spine with my fingertips until I located the clasp of her bra. Unable to see it I fumbled for a moment before unhooking it and letting the material fall to the floor without disturbing her shirt. "If you can get my panties off before my shorts, then I'll be impressed," she said teasingly. "Even I'm not that good," I replied, shaking my head. "Oh well, take what I can get I suppose." Elizabeth lay back on the bed with her legs partially spread and waited for me. I took the time to finish stripping before joining her, aware of her gaze fixing itself instantly on my cock as it came into view. Demonstrating her lack of patience my sister had already pulled her shorts halfway down her legs before I even reached her. I took over and tugged them the rest of the way off, then knelt between her legs. "Hurry up," she urged, wiggling her hips on the bed. I ignored her and took my time to study the damp spot on the front of her panties and breathe in the scent of her obvious arousal. In an effort to speed things up Elizabeth soon began struggling out of her shirt while still lying flat on her back. "I swear, any other guy I tell to hurry up and fuck me wouldn't hesitate for a second," she complained. "And how many guys have you said that too?" I asked. "None of your goddamn business. But if you're gonna be this slow I'll have to go see if I can find one." Giving in I finally grasped the waistband of my sister's panties and pulled them down to her feet. She lay on her back looking up at me with lust evident in her eyes, lust for her own brother. "You know we can't go back from this," I warned. "I know, I don't want to." Elizabeth sighed happily as I positioned myself on top of her and my erection brushed against her waiting pussy. I didn't tease her anymore, simply guiding my cock inside her and slowly pushing deeper. "Fuck, so wrong. So fucking wrong," she murmured beneath, watching me beneath half-closed eyelids. "Mm-hm," I grunted in agreement. "This is going to ruin me you know, ruin regular sex. Nothing else is going to be quite as interesting." Her hands seemed to be all over my back and shoulders, tracing my skin with the tips of her fingernails. I was mostly watching her face as we fucked, loving the way the corner of her mouth twitched upward every time I bottomed out inside her. "Maybe you need to... find someone with a... sister fetish," I panted. "Mmm, maybe. Something to think about." We were both approaching orgasm, or at least I assumed Elizabeth was too by the small whimpering noise she had started making. One of her hands moved down to her clit and began rubbing it frantically as she grew closer. "Oh fuck," she breathed as she came. The muscles in her pussy convulsed around me as a look of pure ecstasy washed over her face. It was that look that did it for me I think, that look of pure sexual bliss that I given to my little sister. I let my cum spurt inside her as she gazed at me adoringly with a satisfied smile on her face. I rolled off of her and lay staring at the ceiling for perhaps a moment or two before Elizabeth broke the silence. "Feels nice having your cum inside me," she told me. "So dirty. Might leave it there for a while, feel it squishing around." "Oh god, shut up Liz. You're gonna get me hard again and we'll be here all day." "There are worse ways to spend time though, aren't there?" she asked, crawling over to me. There certainly were worse fates imaginable I conceded mentally. And besides, it was a long time until next summer.
