He'd hated the Melbourne twins for as long as he could remember, and now he finally had a chance to get even. He pointed to his smartphone screen for emphasis, as if they didn't already know he had just snapped a picture of them making out. "Man, I wonder what your parents will think of this? Good little brothers and sisters don't make out with each other, you know." Ben and Nadia glared at him, their fine-featured faces wearing matched expressions of hate. "What do you want, fucker?" Nadia's blue eyes flashed, and she tossed her golden hair contemptuously. An idea hit Finn suddenly, and he grinned broadly as he ran a hand through his own dark hair. "I haven't had a good lay in forever. Since you two horndogs are clearly in the mood anyway, let's make it a threesome!" His eyes glinted wickedly. "If you satisfy me, I won't show this lovely family photo to your mom and pop." Ben started to stand, his hands balled into fists. "You son of a bitch!" he snarled. "You think you can blackmail us?" But Nadia laid a delicate hand on his chest, holding him back. Ben was no wimp, but Finn had a reputation as the dirtiest fighter at school. "If we do this, you have to let us delete the picture so you can't blackmail us again," she said. Finn smiled, noting to himself that she was the cleverer of the siblings. "Deal," he said. One short, tense car ride later, they were at Finn's place. He took advantage of the twins' distraction as they checked out his place, and quickly texted the photo to his email for safekeeping. "Enter, please, my friends!" He swept the door open, and ushered them in. A short time later, they were naked in his room, Nadia sucking his cock and looking up at him with those electric blue eyes of hers. He moaned and thrust his hips, enjoying the sight of the school's rich princess on her knees serving him. "Oh, that's good," he moaned. "Bet you've had a lot of practice on your brother, hmm?" Nadia's eyes darkened, but she said nothing, and Ben avoided his gaze. Finn just smiled and twined his fingers through Nadia's hair as he started fucking her throat. She gagged and tried to push him away, but he just thrust deeper, sighing happily as her tight throat opened to take him all the way down. When his balls started to tighten, he let her go. "You bastard!" she wiped her mouth angrily. "What did you do that for? I could barely breathe!" In response, he pulled her to her feet and kissed her hard, until she moaned into his mouth. "Doesn't seem like you're really all that angry," he smirked. She stuck her tongue out at him, half annoyed and half playful. Ben had been doing his best to ignore them, but Finn could see that his cock was getting hard despite that. "Hey, Prince Charming, take a turn in your sister's mouth while I fuck her pussy," he said, reaching over to smack Ben's ass. The sandy-haired boy waved Finn's hand away, but positioned himself in front of Nadia's mouth anyway, and she slurped him down hungrily. Before long, Ben was fucking her mouth just like Finn had. Meanwhile, Finn moved behind her and slid a fingertip along her already-wet slit. "You're enjoying this, you little cocksucker!" He slid his finger deep inside her, making her moan. After finger-fucking her to get her ready, Finn slid his hard dick into her pussy in one motion, making her moan and arch her back. He slid in and out, moaning at her heat and tightness, and growing harder when he saw how every thrust pushed her nose against Ben's pubes and made her gag. He slid a hand to tease her clit as he fucked her, and smiled as Ben started tweaking her nipples, making her squirm like a bitch in heat. He smacked her ass and thrust into her hard, loving how her cunt squeezed his cock when he pounded her. After a while he started fucking her slower, so as not to cum just yet. Her legs were already trembling, and her eyes were watering from deepthroating her brother, but he still had more in mind for her. While he fucked her with long, deep strokes, his thumb slipped to her asshole and started making gentle circles. Nadia gurgled in protest and tried to shift away, and the boys' eyes met in understanding. "I've never fucked her there," Ben said, but made no move to stop Finn's exploration. Her tight sphincter slowly gave way as he pushed his thumb deeper, and she moaned. Finn pointed to a bottle of lube on the nightstand, and Ben stopped fucking his sister's mouth long enough to retrieve it. Nadia gasped and tried to squirm away, but Finn held her close. "Please, not there!" she begged. "You're too big for my ass, and you've already fucked me so hard I can barely stand!" Finn stroked her back and buttocks soothingly, leaning over her to whisper in her ear. "I'm going to fuck this tight ass," he told her. "But if you push out like a good little girl, it will hurt less." She whimpered in nervous submission as he pushed his finger deeper, letting his cock slip out of her pussy in preparation for her ass-fucking. She looked to her brother for comfort, and he stroked her cheek as he handed Finn the lube. "It'll be okay, sis," he said. "Besides, I've always said you have a hot ass!" She glared at him and moaned as Finn's now-lubed cockhead pushed at her tight rosebud. She gasped as he pushed past the resistance, deeper into her ass, and she clutched at her brother desperately as her legs started quivering uncontrollably. Unexpectedly, Ben grabbed her head and started fucking her throat again, muffling her screams as Finn fucked her deep in the ass. Finn moaned deep in his throat. He was fucking a hot, stuck-up blonde girl in her ass while she gagged on her brothers cock. This must be what heaven was like, he thought. Before long, Ben exploded in his sister's mouth with a groan of pleasure. She slurped the hot cum up greedily, swallowing as if by reflex, and licking her lips to get the little dribbles that escaped her mouth. Ben sighed happily and began to massage her sides and back, helping her relax for the rough ass-fucking she was enduring. Finn could tell she was starting to enjoy it, though, as she lifted her hips up to meet his thrusts. When she started wiggling her ass in little circles, begging for more, he spanked her and fucked her harder. That drew a reaction immediately. "Oh, yes!" she screamed. "Ream my little ass, you bastard! Fuck me like an ass-slut!" Finn was tempted to empty his balls into her butt, but he still had one more thing planned, so he pulled out, causing Nadia to moan in distress. "Put it back," she pleaded. "I want to feel you cum in my ass." "Maybe later," he replied. "For now, that will be your brother's pleasure." Once again, he enjoyed their shocked looks. Ben predictably started to protest. "No way, man!" he said quickly, backing away from Finn a few steps. "I don't swing that way." But Nadia stepped in at this point, marching up to her brother and grabbing him by the cock. "Listen here, mister," she said. "You let me get fucked in my ass, so you can take the same, or I'll show Mom and Dad the picture myself!" With that, she pushed him onto Finn's bed and forced him to get on all fours, stroking his cock all the while. With a grin, she grabbed the lube and spread his butt cheeks wide, exposing the tight hole. Looking Finn right in the eyes, she slowly slide a lubed-up finger deep into her brother's asshole, making him moan uncomfortably. "C'mon, big boy," she said to Finn. "Come make my brother your bitch just like you did to me." Finn pressed his rock-hard cock against Ben's asshole, enjoying how he clutched the sheets and wiggled his ass nervously, and how his sister pinned him to the bed with her body weight and spread his butt cheeks to help him get fucked. When his cock slipped past the resistance into the other boy's ass, Finn moaned deeply. Nadia moaned too, slapping her brother's ass hard. Ben groaned and whimpered quietly, trying not to cry out. That resolve broke down quickly as Finn started to fuck him pumping his cock in and out slowly, going balls-deep each time. Ben made a noise that was halfway between a moan and a scream, but Nadia still held him down, reaching between his legs to play with his cock. Finn looked deep into her eyes while he fucked her brother, loving the evil spark he saw in those blue orbs. She moved to kiss him suddenly, and he was surprised by the passion. "Fuck my brother hard, stud," she said. "It makes me so hard to watch him taking your cock in his ass!" She kissed him deeper, sliding her tongue against his, and he erupted into Ben's ass, moaning loudly into Nadia's mouth as he came. She continued playing with her brother's cock and balls at the same time, until he too exploded in a hot, sticky mess. She tossed her hair and smiled wickedly as she licked her brother's cum off her hand, then leaned down to clean Finn's cock as it slipped out of Ben's well-fucked ass. Ben crawled off the bed sheepishly, carefully avoiding eye contact with either of his partners. Finn smiled and sighed contentedly as Nadia finished cleaning his cock, then laid her head on his chest. Later, after the twins went home, Finn fired up his computer and checked his email. Noting that the twincest picture was safe and sound, he began dreaming up other ways he could blackmail the siblings. Though given the way Nadia at least had reacted, he thought, blackmail might not be required. Epilogue: Finn and Nadia became college sweethearts, and married soon after graduation. Every now and then, Ben visits -- Nadia jokes that he comes for Finn's cock in his ass. He always protests, but sooner or later, the three end up in the bedroom, and his ass always ends up well-fucked. Sibling Bonding Time Author's Note: As per usual, thanks to LizHaze for editing. **** It was kind of strange how the snow affected us differently. As we walked home I spent most of my time watching where my feet were going and trying not to slip on a hidden icy patch. My sister, on the other hand, preferred to skip along cheerfully while occasionally trying to catch stray snowflakes in her hands and watch them melt. The way Chrissy acted sometimes it was hard to believe she was a twenty year old adult, rather than an abnormally tall kid ten years younger. Granted, other times she feigned being a grown-up so well that she could pass for being the older sibling between the two of us. It was a bit of an odd dichotomy. "How come you look grumpy?" Chrissy asked. I didn't look up. "M'not grumpy," I said. "Just watching where I'm going." "But you're missing all the scenery." "It's snow. Everywhere. I've seen snow before." "What about the Christmas lights. And there's snowflakes. And icicles. And snowmen sometimes." I raised my head and gave her a long eye-rolling stare. She ignored me completely and continued waving her arms around to point out all the things we were passing. I let her go on for another minute or two until I realized she wasn't going to stop on her own. As we passed a decent sized snow bank I put my hand on Chrissy's shoulder and shoved hard. She almost went head-first into the snow, but managed to twist herself around enough before impact that her face stayed clear. "You jerk!" she yelled. I laughed to myself and kept walking. I looked back a couple times as she struggled to her feet, but didn't go back to help. Watching her flounder in the snow helped my mood more than admiring any of her 'scenery' did. Apparently the snow wouldn't support her arms as she tried to push herself up, which meant she eventually had to give in and roll her way back to sturdier ground. If she had been anyone other than my sister I might have felt bad for taking such enjoyment from her misfortune. Once free, Chrissy hurried to catch up with me. I prepared myself for a verbal tirade of reasons why I was a horrible brother, realizing too late that the footsteps I heard behind me weren't slowing down. I started to turn just in time for her to run into me at full speed. She might have been smaller than me, but she still managed to hit me with enough force to knock me off my feet. Since I'd been turning I landed on my back looking up at the sky, as well as my little sister's smug face. "Not as fun when you're the one getting knocked down, is it?" she said. She brushed snow off of herself while I carefully tested the snow around me to see if there was any way to escape with some dignity. My options didn't look good. "And here I thought you'd be trying to get a head start before I get back up," I said. "Well maybe some of us aren't mean enough to leave other people behind in the snow." Chrissy extended a hand to me to help pull me up. It was a nice gesture, considering I'd been the one to start hostilities. I probably should have just taken the peace offering, but I didn't. I took my sister's hand and gripped it tightly. Her eyes widened a split second before I pulled and brought her tumbling down. In hindsight I probably should have tried to force her to the side a bit so she didn't land on top of me, but the effect was still satisfying. "Ugh, I don't know why I trusted you," Chrissy said. "Me neither. Wasn't very clever." She tried to push herself up off of my chest, so I angled my body a little and let her hand slip off the front of my jacket. She made a second attempt, and again I deliberately caused her to fail. "Okay, dummy. You realize that if you don't let me up, you're just gonna have to sit there and get a cold butt, right?" "Be interesting to see how long I keep it up then, won't it?" Chrissy put both of her hands on my shoulders and tried to quickly lever herself into a kneeling position. I grabbed her wrists and yanked them away so she fell back down on me. She struggled against my grip, but wasn't strong enough to break free. All she really managed to do was wiggle around a little and force us slightly deeper into the snow. Unfortunately, my sister's attempts to get away from me led to her more or less grinding on my lap. I didn't pay much attention at first until it began to have an effect on me. I needed to get her away from my cock before I got hard. That would be far too embarrassing to even contemplate. I let go of Chrissy's wrists and made no further effort to stop her from getting up. She pushed herself to her knees, still straddling me, and grinned mischievously. "Letting me go, huh?" she said. "I knew it, you want to get out of the snow 'cause your butt's frozen. Told ya so." "Whatever. You gonna get off or what?" "Maybe." She stayed where she was, practically daring me to make her hurry up. Normally I would have carefully considered whether or not I wanted to give her the satisfaction, but in this case I just needed to get her away from any potential contact with my partial erection. I moved to grab her again, and this time she hopped to her feet before I could get her. I struggled my way out of the snow bank after her, no longer concerned with anything other than making sure my pants didn't appear tented. "Ha! You didn't just get a cold butt, you got a wet butt too," Chrissy said. She examined the back of my pants while I brushed snow off of myself. I was perfectly okay with her taunting me about that. It was better than some of the alternatives. I was pretty sure it annoyed her slightly when I didn't respond the way she hoped. "Alright, let's just get going," I said. "It's getting dark." "S'okay. The streetlights should be coming on soon." "They almost should be on already." I looked up, trying to figure out if it was dark enough that lights should on. "Anyway, let's just go." "Why? You need to change clothes and warm up or something? Wouldn't want to get frostbite on your ass after all. Then you'd feel silly for not listening to me." I faked a lunge at her and she danced away. I trudged onward and did my best to ignore any further attempts she made to bug me. She was right; my pants were damp and uncomfortable from the snow, but I wouldn't admit that to her. "Hey, where'd all the Christmas lights go?" Chrissy asked. I glanced at my sister and found her craning her neck around in various directions. Once I started looking, I also noted that the Christmas lights we'd been walking past seemed to have vanished. "Maybe some people don't have lights up right now," I suggested. "That doesn't seem right. I know some of these houses should have some on, and it makes no sense that none of them would." "Guess you'll just have to live with no holiday cheer for a few minutes. Think you'll make it?" Chrissy punched me lightly on the shoulder. It wasn't enough of a physical assault to warrant retaliation. Shortly after that we arrived home. There were no lights on there either, not even inside. I thought that was a little strange until we got inside and I saw a note by the door. Probably from our parents telling us they'd gone out for a bit or something. I went to flick on a light switch so I could read more easily and nothing happened. "Shit." I flicked the switch up and down a couple times, then tried another one. Suddenly the lack of light around began to make more sense. "Are you gonna turn a light on or what?" Chrissy asked from behind me as she pulled off her boots. "Can't." "What do you mean you can't?" "No power, dipshit." "Hey! Don't be like that. How was I supposed to know?" I shook my head instead of escalating the argument. We shed our jackets and footwear, then moved further into the house. I located a flashlight that had functioning batteries and took it upstairs with me. It wasn't quite dark enough to need it yet, but it soon would be. I swore under my breath as I made my way to my room to change out of my damp pants. I wasn't in the mood for a power outage of indeterminate length. Chrissy tracked me to my room a few minutes later, just as I had finished changing and was headed back downstairs. She snatched my flashlight from me and marched back the way she came without so much as asking if I minded. "What, you couldn't get your own?" I called after her as I followed several steps behind her. "I couldn't find another one. If you can, I'll trade this one back to you." "Hey, now you sound grumpy. How come you're allowed to be but I'm not?" She paused and turned back toward me. "I'm not grumpy, just slightly annoyed. Did you read that note mom and dad left us?" "No. Why?" "'Cause they're gonna be gone for the night. In the middle of a power outage." "Oh." "Yeah. And it's, like, minus ten outside already and we have no heat. How long do you think before we freeze to death?" "Aw, come on, it's not that bad. We just gotta, like, light a fire or something. And the power probably won't be off that long anyway." Chrissy sighed and kept walking. "Right, of course. It's all so simple." **** My sister and I were perhaps not quite as independent and self-sufficient as we should have been. We'd been through power outages before, but never without someone older around to take care of things. That may have been kind of sad for two people in their early twenties, but fortunately we both had enough on our minds that we didn't have to reflect on that. Finding matches was a fair challenge for us. It turned out our parents kept them in a drawer in the kitchen. I had no idea what was wrong with keeping them next to the fireplace. Wood was simpler to locate since it was all stacked in the basement where it had always been. There was some newspaper in the recycling bin to help get a fire started. I had started fires before, though not often, and never when my only source of light to work by was my sister holding a flashlight. It was a unique sort of challenge. It took a couple tries lighting crumpled up newspapers before I could get the wood to start burning. I was eventually successful, and we obtained a source of both heat and light in an otherwise darkened room. Chrissy and I sat down on the couch and watched the fire burn for a couple minutes. It was somehow much more satisfying an experience when the flames represented a small triumph over adversity. "Well, now what?" Chrissy asked eventually. "I dunno," I said. "I kinda hadn't thought this far ahead. Guess we could sit here and wait for the power to come back on." "Yeah, I guess." We lasted another five minutes or so before she started getting antsy again. She kept flicking glances at me, and I could tell she was hoping I'd suggest some course of action before she had to admit she was bored. "You know what I could go for?" she said, finally giving in. "No, what?" "Hot chocolate." "Uh huh. And why would you bring that up when you can't actually make any?" Chrissy grinned in that ever-so-slightly smug way she did when she thought she was being clever. Obviously I'd said exactly what she wanted me to say. "I can totally make some," she said. "If you ask nicely, maybe I'll make some for you too." She hopped off the couch and disappeared into the kitchen, flashlight in hand. I shrugged and went back to letting the fire hypnotize me. I heard the sound of cupboards being opened and rummaged through, but had no intention of going to investigate. I was sure I'd find out soon enough what she was up to. When she returned she had a pot full of water with her. She carefully placed it on the small metal ledge over the fireplace door, then went back to the kitchen. She came back the second time with hot chocolate mix, a bag of marshmallows, and a pair of mugs. She looked even more pleased with herself than before as she retook her seat next to me. "See?" she said. "All I have to do is heat up some water over the fire, then I'm all set." "Aren't you a clever little girl," I said, patting her on the head. "Don't be an ass. You still have to ask nice if you want me to share. You know that's only gonna be worse for you if you pick on me too much before hand." I rolled my eyes. "And what if I don't want any?" "Then I'll have to assume you're being grumpy again and I'll be forced to cheer you up. Who refuses hot chocolate? No one, that's who." "I think you may be making far too broad a generalization." "And I think you may be a party pooper, so nyeh." Chrissy stuck her tongue out at me and I rolled my eyes again. I hated when she made arguments like that. If I played along I'd only encourage her, and if I didn't she'd accuse me of pouting and I still wouldn't win. Luckily, she was too busy keeping on eye on her pot of water to focus her attention on annoying me. She grew more impatient by the minute and kept getting up to take a closer look before sitting back down. The process began to amuse me after the second or third time. "Ugh, why is it taking so long to boil?" she asked. "Maybe 'cause the fireplace isn't really designed to heat pots?" "Well it's hot enough that it should at least heat up a little water." She peered into the pot once more. "Maybe it'd be okay even if it's not boiling. It should still be hot by now, right?" I couldn't see what she was doing since her body blocked my view, but a couple seconds later she yelped and jerked back. She stuck her finger in her mouth as she turned to me. "What did you do, burn yourself?" I asked. "Yes," she said, taking her finger out of her mouth long enough to speak. "Go get me something cold." "Uh, like what?" I said, suddenly having to kick my brain back into gear. It was usually easier not to take anything too seriously around Chrissy, but this was an exception. "I mean, I think we have some ice cubes in the freezer. Or maybe--" "Oh for fuck's sake." She took off out of the room and I followed several steps behind her after grabbing the flashlight. She went out the front door and I found her standing there holding a handful of snow to her injured finger. "Sorry," I said. It was cold outside, but it wasn't bad enough that I couldn't stand it for a minute or two without a jacket. I slipped my feet into my shoes before I stepped out and closed the door behind me so the house would stay a little warmer. We only had the fire for heating the place up, after all. It was almost fully dark out now. A few snowflakes were still falling to the ground, meaning it was almost certainly cloudy enough that there would be no moonlight. It was kind of surreal seeing my sister standing in the snow with only socks on her feet and illuminated solely by the flashlight I held. "It's okay," Chrissy said. "I think my finger'll be fine. It's already pretty much stopped hurting. No thanks to you." "Hey, I had to focus on not panicking," I said, completely deadpan. She stared at me for a moment, then giggled. "Yeah, it was a pretty tense situation all right." "There were life or death decisions to be made, you know. Those aren't easy." "Well, I'm glad you didn't become a doctor then." "Likewise, miss 'can't boil water without injuring herself.' That doesn't exactly fill me with confidence." "Shut up." Our exchange was more a formality than anything. Neither of us really had our heart set on getting under the other's skin. I noticed Chrissy shiver and I glanced back inside. I was beginning to miss the comforting heat of the fire too. I didn't want to be the first to give in though. "Okay, I think I've had enough cold," Chrissy finally said. She dropped the last of the unmelted snow from her hands and pushed past me to get back inside the house. I went in close behind her, and by the time I'd closed the door behind us and kicked off my shoes she'd already made a dash for the fireplace. She huddled in front of it on the floor and pulled off her socks, now damp from the snow she'd been standing in. She looked up at me pitifully. "Can you get me some blankets or something?" she asked. "I'm all frozen now." "Who would've thought standing outside with no winter clothes on would be a bad idea, huh?" "Could you stop being an ass for a second and just get me something to warm me up?" "Fine." I wandered off with the flashlight, only to realize I wasn't sure where mom kept the spare blankets. I knew they existed, I just didn't know where to find them. There weren't any in the linen closet, mostly just sheets and towels and things. Eventually I settled for the easy solution and grabbed the blanket off of my bed and the one off of Chrissy's. I decided against raiding our parents' room. When I returned, my sister was right where I left her, except that she was sipping from a mug of hot chocolate. She must have had more success with it this time around. She turned her head toward me when she heard me approaching. "Is that my blanket?" she asked. "Yeah, and mine too. If you want something different you're gonna have to get it yourself." "No, that's good. Thank you." She set her mug down and took the blankets from me. She spread mine out on the floor underneath her and wrapped hers around herself. "I made you some too," she said as she sat back down and picked her mug back up. I hesitated, trying to decide whether to go back to the couch or not. After a moment I shrugged and sat down next to Chrissy and accepted the mug she handed me. The marshmallows on top were just starting to melt. We drank in near silence for a few minutes. My sister had actually made some pretty good hot chocolate, though it was too hot at first to do anything other than sip at it. I was a little surprised when she leaned on me, but since we were both holding hot drinks it seemed like a bad time to start a fight over it. Besides, with nothing else to lean on, supporting some of our wait against each other wasn't a terrible idea. "You'd think the power'd be back on by now," I said. "It's not like there's a storm out there or anything." "Yeah, but there's no way to know. Maybe someone ran into a pole and knocked it over." "That'd take some doing. I don't think I've ever seen one come down." "Me either. Not much we can do about it anyway." "I know. All we can do is sit and wait." **** The power didn't come back on. Chrissy and I sat in the dark room talking and watching the fire, all the while growing increasingly bored. We had very limited means with which to entertain one another. Our only real activity was to go to the kitchen and make sandwiches when we got hungry. We had very limited options for feeding ourselves, what with not having a funtional stove, microwave, or oven. It was one of the few times in my life when cooking something would have been a welcome distraction, and we didn't even have the option. Chrissy eventually lay down facing the fire, covering herself with her blanket. I didn't think she was tired so much as seeking a more comfortable position. The floor wasn't particularly soft, even with a blanket to pad it slightly. "You planning on sleeping here or something?" I asked. "Hopefully not," she said. "But at this rate I might have to. You probably should too, seeing as how your room has no heat or blankets." "I... how's that going to work exactly?" Chrissy smiled in amusement. "You aren't scared of sleeping next to your baby sis, are you?" I actually was kind of worried about sleeping too close to her. I'd nearly poked her with my erection once already, I didn't want to chance it again. Especially when I'd be asleep and unable to do anything about it. "No, just concerned you're gonna steal all the covers," I lied. "Well then I guess you'll have to steal them back if I do." "Right. Or we could sleep separately." Sibling Bonding Time She shrugged. "Suit yourself. You can sleep wherever you want. You're not taking either of my blankets though." I sighed and had to resist the urge once again to check the time. All the clocks were nonfunctional, but I kept forgetting that. It was kind of annoying not to have a sense of how much time had passed. I was kind of worried that I might not be able to hold out long enough for the power to come back on and I'd have to sleep beside my sister. It was either that or try to scrounge enough clothes and bedding to keep myself warm through insulated body heat alone. Neither option sounded attractive to me. I contemplated the idea of arguing that one of the blankets Chrissy had was mine, and that she didn't really have a claim over it. However, I knew that it would be an exercise in futility even without making the attempt. "You know what?" Chrissy said. "No, what?" "We should have pillows down here." "'Kay, well I went last time. It's your turn to get supplies." "I made hot chocolate." "And I did most of the work on the sandwiches. You just held the flashlight." Chrissy shifted around until she was on her back. The light from the fire cast strange shadows across her face from that angle. "I'll make you a deal," she said. "What's the deal?" "You go get the pillows, and I'll let you be the little spoon when we sleep." "Fuck off." I rose, wobbling a little from having sat for too long. "Or you can be on the outside if you want. I'll let you choose, how's that?" I ignored my sister until I got out of the room. She probably thought she was being funny, but I had a different view on the matter. It would have been really nice to have some kind of option as to where I slept, but other than the room we'd staked out the rest of the house was way too cold. On the other hand, the way Chrissy was going she might well push me past the point of caring. It wasn't like I'd be the only one who'd be uncomfortable with the situation if I accidentally poked her with my cock during the night. I gave serious consideration to just spooning her like she wanted and pretending I didn't notice if and when I started getting hard. Unfortunately, that sort of thing could easily turn into a game of chicken and I wasn't sure that she'd back down first. I returned to my sister a few minutes later after snagging the pillows off of her bed. I handed her one and took the other for myself, setting it beside me as I sat back down. Despite having been gone for only a short time, the fire's warmth was a welcome change from the chill of the rest of the house. Chrissy positioned her pillow under her head and lay still for a bit. I was a little confused when she abruptly began squirming under the blanket that covered her. A moment later she pulled her pants out from underneath her blanket and set them aside. "What are you doing now?" I asked. "Getting ready for bed." She paused for a second. "Getting ready to go to sleep anyway. I guess it's not really a bed." She pulled her bra from under the blanket next, which went on top of her pants. I shook my head and tried not to show how much more nervous I was of the situation now that she was stripping down. "And I here I thought you were cold," I said. "I was, but the fire warmed me up. Besides, I don't know about you, but I'm not used to sleeping fully clothed. You aren't gonna sleep wearing your whole outfit, are you?" "Maybe I am. Doesn't matter to you, does it?" Chrissy was quiet for a couple minutes. I couldn't see her face, but I assumed she had simply dropped the conversation. For all I knew she might have decided to try and go to sleep. "Are you mad at me?" she asked, startling me slightly with her question. "What?" "You just seem kind of... touchy. Maybe that's not the right word. Something seems off though." "No, I'm not mad at you. You're annoying at times, but it's not like I'm not used to that." "Gee, thanks." "Hey, don't take it personally. It comes with being a younger sibling as far as I can tell. There's nothing you can do about it." "Does being the older sibling make you grumpy? Is that your excuse?" "I'm not grumpy." "If you say so." I sighed and once again regretted my lack of options for sleeping arrangements. It looked like I might be in for a long night. Despite my reluctance to remove clothing, I took my pants off before lying down next to Chrissy. It might keep her from bugging me about the issue any further, not to mention it would be far more comfortable. What with the fire and our shared body heat, I didn't think I'd need my pants on to stay warm. I settled in on my back several inches away from my sister and shifted my pillow underneath my head. I grabbed the edge of the blanket we'd be sharing and tugged on it to try and cover myself. Chrissy resisted my efforts. "You have to get closer," she said. "It won't reach otherwise." I sighed louder this time, then scooted over until my body was almost touching hers. The blanket covered us both at that distance, but only just. It wasn't too late, I could still go get the one off of our parents' bed if I wanted. I kind of wished I'd just sucked it up earlier and grabbed it when I'd gotten the other two. The thought of venturing back into the cold part of the house seemed incredibly unappealing. Even my forced proximity to my sister wasn't enough motivation. Just when I thought I was safe, Chrissy moved. She pushed herself toward me enough that her back was touching my arm. Apparently she'd decided that we hadn't been close enough yet. "A little physical contact isn't gonna kill you," she said. "But why take the chance," I muttered quietly enough that I wasn't sure if she heard me. I tried my best to fall asleep. In all likelihood I probably tried too hard. I just wanted to wake up the next day with the power back on and everything back to normal. I failed miserably. I lay there for what seemed like hours staring up at the darkness of the ceiling, trying not to move too much lest I disturb my sister. It was hard to tell when Chrissy fell asleep, or whether she might even still be awake. She hadn't changed position and still faced away from me, making it difficult to know what her status was at any point in time. All I had to go on was the slow rise and fall of her body as she breathed. It seemed calm and steady, but that didn't necessarily mean anything. Eventually I had to face the fact that I wasn't going to get to sleep the way I was going. A lot of the problem was probably from being on the floor with only the limited padding of a blanket between me and it. If I was going to have any chance of rest I needed to stop worrying and allow myself to get as comfortable as possible. I moved carefully, hoping that Chrissy was asleep as I rolled onto my side facing her. Embarrassing as it may have been to spoon my baby sister, I couldn't deny that the position held a certain temptation for me. It meant I could watch the fire over her shoulder, which was hypnotizing enough that it might help. I also couldn't deny that her warmth and softness was nice to snuggle up to. As I wrapped my arm around Chrissy's waist, my heart started beating a little faster. That was kind of counter productive as far as my sleeping goals were concerned, but I was sure it would go away. I wasn't sure why I felt so nervous about getting caught. She'd been the one insisting on us sleeping together, and had been the one to suggest cuddling as well. It wasn't like I was doing anything she could object to. After a couple minutes I began to relax. There had been no reaction from my sister, and I was getting more and more comfortable with being so close to her. Then her hand moved and came to rest on mine. I tensed up again instantly, but she didn't actually say anything and just cupped my hand in hers. It seemed more like an acceptance of my closeness than anything. "Still awake, huh?" I said. "Yeah. I was kinda drifting a little, but I can't seem to really get to sleep." "Same." "Of course, it probably doesn't help that we went to bed way earlier than normal. I think. Stupid clocks not working makes it hard to know." "Yeah, I s'pose." Chrissy squeezed my hand gently, but I wasn't sure what the gesture was meant to convey. I stayed silent since that seemed like a safe option. "Tonight's not all bad though," she said. "I mean, it is kinda nice hanging out with you. We don't do it that often." "What do you mean? We see each other all the time." "Yeah, but we almost never actually hang out. You know; just us, killing time, no ulterior motives... it's nice. That's all." "Well... there are far worse people out there to be trapped with for an evening. I'll give you that." "Guess that's as good as I'm gonna get, huh?" She squirmed back against me, pressing her body to mine a little more firmly. I wouldn't have minded, except that my cock had already been on the fence as to whether or not it wanted to get hard. Her butt wiggling against it was very much the opposite of helpful in that matter. I pulled my hips back from Chrissy just enough to put a little space between us there. I tried to be inconspicuous about it, hoping the lack of contact in that one area wouldn't be noticeable. Unfortunately, I had no such luck. She pushed her butt toward me again, more forcefully this time. There was no way I'd keep my growing erection hidden if she didn't stop. "Could you maybe... you know, scoot forward a bit?" I asked. "Don't worry about it," she said softly. "What?" "Don't make it weird. I'm pretty sure I know why you've been acting funny, and you don't need to worry so much about it." "I... there's no way it's not gonna be weird. You know, assuming we're thinking of the same thing." Chrissy sighed, then rolled in place onto her back. She turned her head to look at me, then shook her head slightly and rolled the rest of the way over so we were facing each other. "Look," she said, "if I were behind you and my boobs were touching you, would that bother you?" "Um... no, not 'bother' as such." "It wouldn't freak you out to feel your sister's boobies?" "No, but--" "Do the math, dumbass. I don't want to have to spell it out for you." We stared at each other for a moment. I was pretty sure I knew what she was getting at, but I wasn't quite certain. "No complaining about me poking you later when you change your mind," I said quietly. "I'll have no sympathy." "Deal," she said, a faint smirk barely evident on her lips in the dim, flickering light. She rolled back over and I spooned up to her again. I was still kind of hesitant, especially since I was semi-hard at that point, but she truly didn't seem to mind feeling my cock against her butt. Maybe it really wasn't a big deal. It was always hard to know what people's reactions would be to an uninvited erection, partly because I did my best to never find out. It took several minutes before I could begin to relax properly. I kept expecting Chrissy to change her mind and tell me to get away from her or something. Once I managed to settle in, it actually felt kind of nice; nicer than before I'd had an erection. Having something pressing against my cock always felt good, and a girl's butt was on a completely different level from most other options. The main problem with the situation was that I was getting increasingly turned on. I didn't mean to, but my body didn't let me make the decision. My concern gradually shifted from my sister's comfort to my own. Usually I could just jerk off and be done with it, but that didn't seem like a great plan in this case. All I could do was hope my penis would settle down on its own. "You're getting really hard," Chrissy whispered. "Yeah, well... what did you expect?" "I dunno. Didn't think about it too much. Is it gonna go away?" "Maybe. I don't know yet." She seemed to accept that, even if it wasn't much in the way of reassurance. I honestly wasn't sure what would happen if I ended up needing to get off. I was hoping it wouldn't come to that. Chrissy wiggled slightly, making me groan at the sudden, unexpected stimulation on my cock. She must have just been shifting her position, but for a second I thought she was grinding her butt against me on purpose. Crazy as the idea was, it wasn't actually as far from the realm of possibility as it should have been. It had been a weird evening so far, and the trend seemed to be continuing. "Can you not move so much?" I asked. "You want me to stay completely still?" "Well... kind of, yeah." She looked over her shoulder at me, then deliberately wiggled her butt again. She didn't even pretend to be apologetic about it. "So you don't want me to do things like that?" she asked. "You know very well what--" I grabbed her hip as she started moving again. I couldn't keep her totally still, but it did limit her range of motion. Chrissy giggled softly as I tried to hold her still. "Sorry," she said. "No you're not." "You're right, I'm not. I'm just messing around though. You know that, right?" "I know. It's just...." "Weird?" "Yeah. That." Chrissy stayed still for a few minutes. I kept my hands on her at first, but when she didn't move I gradually let my guard down. My lower arm had gotten pinned between us when I was trying to restrain her and the position was getting to be kind of painful. I adjusted my position in order to free my arm, and in the process managed to accidentally slide my cock between my sister's butt cheeks. Our underwear separated us, but it was still a highly inappropriate position to be in. She, of course, just laughed. "Now who's being naughty?" she teased. "Shut up. You know that wasn't on purpose." "Seemed pretty deliberate to me." "Shut up," I repeated. She kept giggling, but at least she didn't say anything else. The way she was acting was beginning to bug me just enough to make me consider some ill-advised acts of retribution. Chrissy fell silent for a moment, then burst into another fit of giggles just when I thought she was done. That was the point when I gave up on trying to play defensively, so to speak. I rocked my hips slightly, sliding my shaft along the cleft of her ass. She gasped and, thankfully, stopped laughing. "Okay, that was definitely on purpose," she said. "You think so?" I repeated the motion, eliciting another gasp from my sister, albeit a much softer one. When I didn't stop after the third or fourth thrust, I was forced to admit to myself that it really wasn't all about trying to shut her up. It also felt really, really good. I should have stopped on my own. Failing that, Chrissy should have stopped me. Neither of those things happened. I was grinding on my sister in an unequivocally sexual way and we were both just letting it happen. This was officially the weirdest night of my life. Things got even weirder when I heard Chrissy moan. It wasn't very loud, and was more than likely involuntary on her part, but it was there. I wasn't the only one enjoying the illicit contact between us. "Tell me to stop," I said. She said nothing. "Come on, Chrissy. Just... just say it." "Don't worry so much," she whispered. That wasn't what I wanted to hear from her. In fact, it was kind of the opposite of what I'd been hoping for. I wasn't as in control of myself as I should have been, and apparently I couldn't rely on her to make up for that. My arousal was killing my sense of rationality. "We're gonna regret this tomorrow," I muttered, mostly to myself. I pulled my underwear down and kicked it off my feet. Chrissy's panties were still on, but they'd been getting pushed between her butt cheeks by my cock and weren't covering as much of her as they usually would. As I kept grinding on her, my cock rubbed mostly against bare flesh. It was difficult not to imagine what would happen if I took things even further. Part of me wanted to take my sister's panties off, maybe even strip her completely naked. Or at least see how far I could go before she put a stop to it. I needed a voice of reason and restraint, and if I couldn't get one I'd just have to keep going until something gave. Maybe Chrissy would step in, maybe I'd cum and regain control, or maybe there was some third option that hadn't occurred to me yet. In the face of Chrissy's silent consent, I reached my hand to her chest and slowly eased my fingers over the curve of her breast. She sucked in air between her teeth at my touch, but still didn't make any real complaint. I was seriously beginning to think that she was giving me free reign to do whatever I wanted. I alternated between her boobs, squeezing each gently through her t-shirt. They fit nicely in my palm, and were wonderfully soft to my touch. It was like they were made for me to play with. Once again I contemplated the merits of getting her naked. I knew her breasts would feel even better without her shirt in the way. Chrissy had been keeping fairly still, but suddenly that changed. Her hips started rocking back against mine in barely perceptible movements that gradually became more forceful. I moaned into her shoulder as my cock received the benefits of both of our efforts. Apparently still unsatisfied with how far things had gotten, she paused just long enough to pull her panties down. My shaft was left sliding against her bare ass. The physical and mental ramifications of that fact competed inside me for dominance, but it didn't really matter which one affected me more. I was using my little sister's half-naked body to get myself off. The details were about as significant as a handful of sand in the middle of the Sahara. "This is so fucking wrong," I breathed, unable to stop myself from thrusting against her all the while. "Are you gonna cum?" she asked. "Yes," I grunted. "So close...." Chrissy nodded. Her rhythm remained steady and she squeezed my cock between her ass cheeks a little without interrupting our movement. I was helpless to resist any of it at that point. All I could do was keep going until the very end. I came hard, shooting my load onto my sister's butt, and getting some on myself in the process. There was so much more of it than when I jerked off by myself, and my cock just kept spurting more and more, making a mess of our lower bodies. She kept rocking gently back against me even after I was done until gradually falling still. "Feels like my butt's all sticky now," she said. "No kidding." Chrissy wiped ineffectively at the cum with her fingers. When that didn't work, she grabbed her discarded pants and used one of the legs to clear most of the mess off of her butt. I watched the process with detached interest. I was expecting myself to freak out or experience a massive wave of guilt at any moment. So far I was feeling calm enough, but there was no telling how long that would last. "Do you really think you'll regret this?" Chrissy asked. "Or were you just saying that?" I hesitated, finding myself unable to tell her that of course I'd regret it, and that she should too. That was more of a knee-jerk reaction to the situation than anything else. At that moment, I honestly wasn't sure how I'd feel about tomorrow, or a week later, or even in five minutes. More important than any rational consideration, however, was the certainty that a poorly chosen answer would hurt Chrissy. I had to be delicate in my response, and possibly not entirely truthful depending on how the conversation went. "Right now... I don't regret it," I said. "I should, but... I dunno, the guilt's just not there." "What about tomorrow?" "Hard to know. Ask me again when we get there. What about you?" Chrissy shook her head. "I don't feel bad about it. Don't think I will later either." Sibling Bonding Time "Well that's... good. Right?" "Probably. Hopefully." One of my arms was still draped around her. She moved her hand to mine and entwined our fingers, giving a slight squeeze. I squeezed back gently in what I hoped was a sign of reassurance. The fire was burning low by that point and would probably need more wood soon. It wasn't in critical shape yet and I didn't feel like moving, so I left it alone for the moment. It was somehow even more hypnotizing when I could pick out smaller, more isolated flames to watch. Having something to focus on must have helped keep my mental state from going into panic mode, because I was still feeling pretty good. It was kind of worrying that I didn't feel even a minor sense of self-loathing yet. I wondered how Chrissy was feeling. She must have been going through at least a small internal conflict, I assumed. I still had no idea what her motivation could have been for enabling my rogue hormones. "Why?" I asked. "Why what?" "You know what. You know exactly what. I just... I don't get it." "You mean why'd I let you do stuff to me?" she said softly. "Yeah. That." She shrugged and didn't say anything. I waited for a moment, but no explanation was forthcoming. Sensing that I'd need to prod her a little, I moved back an inch or two and tugged on her shoulder. She resisted at first, then gave in and let me roll her onto her back. Her expression was unreadable to me, neither overly happy or upset. "Chrissy, c'mon. You know I'm gonna be curious about something like that. I was horny, for as much of an excuse as that is. Why'd you do it?" "You think I'm a perv, don't you?" "Not particularly. No more than me, at any rate." She smiled faintly. "I don't know why I did it. Not exactly. I mean, I kinda do, but...." "But what?" "You're gonna think this is dumb." "Maybe. Won't know for sure until you tell me." "You know how I was saying it's nice getting to hang out tonight? I thought... I thought maybe I could make it better for you. You know, so you'd want to hang out more." "So you were, what, bribing me? You could have just said something." She looked away for a moment, then back to me. The firelight caught her eyes at just the right angle to give them the appearance of piercing right through me. "I practically had to beg to get you to sleep close to me. You always get so weird about stuff like that. It's like you think I don't know what erections are." "Well... I mean, it is a bit weird to deal with that stuff around you. Although, in comparison, I guess most of it seems irrelevant next to what we just did." "Yeah, that was kind of the point. That's one less excuse for not spending time with me." I started to ask what she meant by that, then stopped myself. I knew what she meant; it wasn't all that difficult to figure out. Apparently I'd been so oblivious to certain sub-par facets of our relationship that she'd had to resort to drastic measures to get my attention. "Guess I made things tricky, huh?" I said. "A little. To be fair, letting you get off on my butt like that was probably excessive, but it got results. We've both been lying here half-naked for... well, several minutes now at least, and you haven't even tried to put space between us yet." "Didn't seem necessary." "Good, 'cause it isn't." Without really thinking about it I pulled Chrissy to me and hugged her in my arms. She accepted the embrace contentedly while I did my best to ignore the unclothed parts of her that pressed against me. I wasn't worried about getting turned on again so much, except that I felt it would ruin the moment if my cock started poking her. "Kinda wish you'd waited a minute before going into cuddle mode," she said. "Um... why exactly?" "'Cause the fire needs more wood and one of us is gonna have to deal with that pretty soon." I glanced at the fire, though I was already aware it was getting low. She was right; it would have been nice if we'd dealt with that before getting all snuggly together. "Just go do it," I said. "You're practically right next to it and it'll only take a second." "Why do I have to do it? You just want to perv on me when I get out from under the blanket." "I can neither confirm nor deny that statement." Chrissy rolled her eyes, then appeared to change her mind. She smirked mischievously at me. "Admit you just want to look at my butt and I'll do it," she said. "What if that's not actually the reason?" "Then I'll be slightly annoyed. Besides, what other reason is there?" I decided not to argue the point. My attention hadn't initially been to "perv on her," as she put it, but I couldn't deny the appeal. It definitely wouldn't be a complete lie. "Okay, I just want to look at your butt," I said. "That's what I thought." Chrissy rolled away from me and sat up. She took a moment to smooth out her hair, then flipped the blanket away from her. I couldn't really see much of any interest until she climbed to her feet and gave me a good view of her ass. Her shirt didn't come down far enough to cover it and I stared at it in sudden fascination as she walked the few steps to the fireplace. She looked over her shoulder at me and seemed amused at my reaction. She bent down slowly and took her time opening the door and putting wood in. The show she was giving me pretty much confirmed that she was enjoying the attention she was receiving. "Never knew you were such a show-off," I said. "I'm usually not. Tonight's... special." "Special huh?" "Yeah. Who knows if anything like this is ever gonna happen again. I want to make this chance count." "Well, I think it's safe to say this isn't a night I'm likely to ever forget. That's something, right?" Chrissy smiled as she crawled back in next to me. "Yeah, it's definitely something. It'll be kind of nice to be able to look back and know that for a little while all your attention was on me." She pulled the blanket back over us and snuggled down beside me. I didn't immediately settle in with her. "Is that what you want?" I asked softly. "What, attention? Yeah. Doesn't everybody?" "Not from their brother. Not the way you went about it." "Lots of people want to know they matter to their big brother. Probably. I do anyway. I'm not gonna try and argue that my methods aren't... unorthodox." I wrapped my arm around her and rested my head against hers. "You matter to me," I said. "Even if I could probably do a better job of showing it most of the time." "Well you'll know better now, won't you? 'Specially now that you know how fantastic my ass is," she teased. "Yeah. Me admiring your butt certainly seems like a solid foundation for our relationship." "Shut up. It's not a 'foundation,' mister smarty-pants. It's just... helpful. It changes things. Hopefully for the better." "Hopefully," I agreed. After Chrissy's little 'show,' and the subsequent closeness of our bodies, my cock was once again threatening to get hard. We were positioned in such a way that I didn't think she'd notice, and at first she didn't. Then she shifted and her hip grazed my growing erection. "Mmm, guess you really do like my butt," she said. I said nothing. Chrissy waited a moment, then moved her arm and traced her fingers along my leg toward my waist. I knew where she was going, but it seemed far too surreal that she'd actually-- My thoughts were interrupted as I felt her delicate touch on my shaft. She was looking directly into my eyes, searching my face and delivering an unspoken question. It seemed so ridiculous for her to ask permission under the circumstances, and yet no less ridiculous that I was prepared to give it so easily to my own sister. "Go ahead," I whispered. She nodded, taking a firmer grasp of my rapidly stiffening cock. I let out a low moan at the sensation, making the corner of her lips twitch upward in amusement. Her hand slid up and down my length in slow, exploratory movements. "It feels so different when I hold it," she said. "Is that good or bad?" She shrugged. "Neither. It just is." "Okay then." Chrissy's grip tightened on me as I became fully erect. She still wasn't actually jerking me off, or I didn't think so anyway. The difference between exploring via touch and trying to get me off was not a clear one. I was fine with just lying there and letting her do her thing. Regardless of intent, it did feel good. "How weird is it that I kinda like playing with your penis?" she asked quietly. "Relatively speaking? Not all that weird, really. If we're being honest, I'm kind of enjoying it too." She smiled and snuggled in a little closer, making sure to leave enough room for her hand to move freely. "This could be our thing, you know." "I don't follow." "Like, we could do this sort of thing sometimes. Mess around a little. It'd be a reason to hang out." "You're really desperate for some sibling bonding time, huh?" "Maybe. Are you trying to tell me you're not interested?" I thought about it for a moment, but I knew what my answer was as soon as Chrissy had asked the question. The feeling of her hand on my cock had a way of simplifying a decision that probably should have taken more consideration. "I'm not saying I'm not interested," I said. "I think you'd know I was lying if I tried." "I'd be pretty confident you were lying," she confirmed. "Seriously though, do you think this is gonna happen again?" "Yeah, I think so. It's hard to imagine us both just dropping this and forgetting about it." Chrissy's head was tilted forward so all I could see was her hair. Even though I couldn't see her face, I was pretty sure she liked my response. Part of that might simply have been the realization that the way she was toying with me was slowly transitioning into an actual handjob. Her fingers encircled my shaft in a full-handed grip, and her strokes became steady and smooth. Suddenly she tilted her face up toward me. Before I could react, she moved in and pressed her lips to mine in a gentle, slightly uncoordinated way. I was surprised by her action, although not particularly disturbed by it. I was really getting the hang of going with the flow over the past little while. She pulled back after a few seconds. "Sorry," she said. "I probably shouldn't have done that." "It's fine," I said. "Are you sure? I'm not even sure why I did it. I just--" I put my hand on her cheek and cut her off by kissing her back. She accepted the kiss with only a slight hesitation, eagerly molding her lips to mine. I held the embrace long enough for her to know I meant it, then tried to break it off. "So I think--" I started. Chrissy cut me off this time, resuming our kiss more aggressively. She used both of her hands to hold my head close to her, abandoning my cock to fend for itself. Things might have been different than usual that night, but my brotherly instincts weren't completely shut down. I had an ingrained, adverse reaction to my sister simultaneously trying to take charge and taking away something I was enjoying. I tried pushing her onto her back, but I couldn't get her to let go and had to roll along with her. The maneuver left me on top of her, my erection dangerously close to her pussy. I felt my shaft unintentionally brush lightly against her slit, but she didn't seem to mind. Certainly not enough to unlock our mouths and say something. Grinding on her butt earlier had worked out well enough somehow. I realized too late that if I tried the same thing from the front, things could escalate far too easily. Accidental penetration wasn't something I wanted to casually risk for the sake of getting off. Maybe if I just asked her she'd go back to the handjob she'd started giving me. "Hey," I said, managing to pull my head back momentarily. "You wanna--" Chrissy was no longer in a talking kind of mood. She forced my face back down and tried to keep me quiet by blocking my mouth with her tongue. "Hey!" I tried again, once more struggling free of her grip. "What?" she said. "I thought it was okay." "Yeah, but... there's something else you need to take care of." Chrissy giggled and reached down to my cock. She wrapped her fingers around it, but didn't immediately start stroking. "Sorry," she said. "Didn't mean to leave you hanging like that." "It's not nice getting me all horny like that then not taking care of it, you know." "I know." She giggled again, then bit her lip. "I've got an idea that might be really, really stupid." "Oh yeah? What is it?" "'Cause, like, I don't know if you noticed, but I'm pretty worked up right now too." "Uh huh, but what's the idea?" Chrissy didn't answer me right away, and I started to think she might have changed her mind without even telling me. Then I felt something graze my cock. I assumed it was an accident at first, that perhaps she'd bumped her leg into me or something, but then it happened again. It dawned on me that she was purposefully lifting her lower body just enough to make contact. Once I caught on, it became obvious what she was thinking about doing. "Oh god, Chrissy...." "It's a bad idea, isn't it?" "It is, but... I don't know if I can say no." "You do seem to have problems with that sort of thing." I lowered my hips a little and felt the head of my cock press against her pussy lips. They were wet against my sensitive tip, and warm. Almost hot. I tried to distract myself from thinking about how good it would feel to let myself sink into her. It would be so easy. She was practically inviting me to do it. "You're not exactly saying no either," I said. "In fact, I'm pretty sure you're doing the opposite of that." She shrugged. "I didn't even get off yet so I'm probably hornier than you are. What do expect me to do?" Her pussy pressed against me more forcefully, then backed off. I closed my eyes for a second and tried to breathe normally, but was having difficulty. I wanted so badly to give in. Neither of us had surrendered yet, not completely, but we were both right on the edge. I reached down and took my cock in my hand. I slid the tip back and forth across my sister's wet slit, making her hiss in surprised pleasure. All I would need to do was push a little against her entrance and I'd be in. That was all it would take. "Last chance," I said. Chrissy shook her head. "Don't tease me." I leaned down and kissed her as I lowered my hips. Her pussy barely resisted me before opening up and engulfing the head of my cock. I groaned into her mouth and had to break off the kiss as I sank deeper into her. I'd thought that I knew what to expect, but I was unprepared for just how tight she was around my shaft. Her inner muscles seemed to grip me as though they wanted to swallow me and never let go. If she hadn't been so wet, I didn't think I would have been able to make any progress at all. "Fuuuck," Chrissy breathed, mirroring my thoughts. I thrust into her, forcing my cock deeper into her tight hole. She moaned loudly, making me glad we were alone. Even the threat of getting caught wouldn't have been enough to stop me at that point, but it was better not to have to worry about it at all. It was just us surrounded by the dark and cold in our little bubble of warmth and sex. There was no one around to interfere. Chrissy's hands ran up my back under my shirt, her fingers running along my skin as they traced down, sometimes all the way to my butt, before making their way back up. Her grip was strengthening, alternating between simple rubbing and fondling and pulling me toward her. She wanted me closer, but as I bottomed out inside her I could get no closer. I liked that she was still trying to get more from me, that her desire went beyond mere physical limitations. We got into a rhythm as I began to take long, steady strokes. My cock sank completely into her on every thrust, her pussy taking my entire length despite its tightness. She squeezed me even more tightly every time I pulled back, then rocked her hips against me when I pushed back in. "Keep going," she whispered. "Keep going." "I'm... not... gonna stop," I assured her, beginning to pant from the exertion. I had no intention of stopping before I came. Strange as it may have been, fucking my sister was the best feeling I'd had in my entire life. Everything about it was amazing: the way her pussy gripped me, the way she looked at me with a unique mixture of love and lust, the fact that we absolutely should not have been doing what we were doing.... I'd always loved Chrissy in the way that siblings have to, but there was something new now, something that hadn't been there before. It was like our physical connection had resulted in bringing us closer together emotionally as well. "So close," she moaned. "Don't stop." My orgasm was building as well, though not quite as quickly as hers seemed to be. Her breathing was quickening, her fingers were tightening their grasp on my body, and her moans were growing stronger with every thrust. I briefly considered slowing down for a few seconds just to tease her, but rejected the idea. It wouldn't have been worth ruining the moment. It wasn't long before Chrissy came. There was no doubt when it happened; she kept telling me over and over again that she was cumming, and I was again relieved that no one was around to hear. Between her vocalization and thrashing around underneath me, anyone within earshot would have been immediately able to figure out what was going on. I kept thrusting into her, pounding her tight little pussy with increasing desperation. I was at a point where nothing mattered anymore except my imminent release. My muscles complained and threatened to give out on me, but they held out long enough. With a final burst of effort I pulled out and jerked myself off, shooting my cum all over my baby sister's tummy. Chrissy had mostly come down from her high and watched in detached fascination as her skin and shirt were covered with my semen. She giggled as some landed near her breasts and wiped at it with her finger. "You made another mess," she said, unable to prevent my cum from soaking into her shirt. I couldn't help smiling at her observation before rolling off of her. "Yeah. I did. And I'm not even sorry about it." Chrissy snuggled up beside me, probably rubbing some of my cum from her shirt to mine in the process. I was pretty sure neither of us actually gave a shit about the mess at that point. "So," she said. "Wasn't a bad night, huh? Even with the power off and all." "No, not so bad. We should hang out more often." She giggled again. "Totally. How 'bout tomorrow night?" "Hm, I dunno," I said, reverting to my desire to tease my sister now that my hormones were taking a break. "I might have plans. I'll have to let you know." Chrissy punched me lightly on the chest. "Yeah right. You don't have plans." "How would you know?" "I just do. S'okay though, I know where you sleep." "Was that a threat?" She shrugged and rested her head on my arm. She seemed ready to fall asleep at any moment, and I was getting to the point of nodding off as well. If there was anything more to be said, it could wait. We were both on the same page and I was sure she knew it despite my teasing. I didn't know exactly what my sister might be planning for the next night, but I was looking forward to finding out.
