That was the one benefit of this stupid challenge, if you didnt count what had happened the day before a nice breakfast instead of just a bowl of cereal before rushing off to school. But Id still rather have my computer and all the other conveniences of a modern life mankind had worked hard to achieve. School was okay. I was still getting some teasing from friends about being cut off from the Net and cell phones, and having to be told the news about what was going on in their lives instead of having learned it real time from text messages or IMs, but at least we had something to talk about during lunch and between classes, instead of having run out of discussions. It got so that I was kind of dreading the weekend. School, for all that it was a hassle, had become something of a lifeline to my friends, since I couldnt talk to them outside of it. On the bus ride home I tried to imagine the horrible family events wed be forced to do over the weekend. Krista sat a few seats ahead of me on the bus, occasionally looking in my direction but mostly talking with her friends. That was another thing I was worried about. Id have a few hours alone in the house with her, and if she regretted what we had done it could get very awkward between us. I walked a little ahead of her to the door, but in silence. At first Id thought wed likely continue this trend and just retreat to our separate rooms. But the moment she closed the door behind her, she said, Bobby, I think we should talk about what we did yesterday. I breathed out deeply, and then turned around, preparing for the worst. Okay. You know how I was pretending you were just some guy, and you were pretending I was just some girl? I nodded dumbly. Well, I was thinking, maybe we could try that again, for other things. It seems like a good arrangement. My cock sprang to attention. What do you mean? Krista stared, not at me, but towards the table where Mom usually throws the mail, like she was a little embarrassed. It could be a good way to practice things. You know, like things were not sure were doing right, with girls or boys? Like Im sure there are things youre not sure how to do with a girl, right? Sure. Lots, really. I gave a brief, nervous chuckle. My heart had started to pound. Well, if you want, we could help each other out. It could be fun, and its not like we have anything else to do till Mom gets home, right? Right, I said. So what did you have in mind? I dont know. You go first. What are you most nervous about with a girl? Practically everything. Kissing, I guess, I said, automatically. How do you know if youre a good kisser? Googling kissing techniques is unhelpful. Then I realized just what Id said, and to who Id said it to. But I know thats probably too weird No, we can do that, she said quickly. Lets go to your room? I led the way, trying to act casual, but I could feel my legs starting to shake, like they did whenever I was about to do something with a girl for the first time. In my room, I tossed my schoolbag on the floor and sat on the bed, hands on my knees. My sister sat beside me, one leg on the bed, turned towards me. Just pretend Im a girl you like, she said. Ill close my eyes and pretend youre somebody else. She shut her eyelids, left her mouth open very slightly. I could finally look at her straight on with her eyes closed. She really was lovely, if she wasnt my sister I could probably fall in love with her just based on her face. She had one of those faces that had two different modes, both beautiful. When it was relaxed, she looked like one of those distant, untouchable beauties, lost in thought. But when she smiled, she seemed approachable, sweet, even playful, the girl next door, or, in my case, down the hall. She wasnt smiling now, so it was a strange sight, her looking like an unapproachable goddess, just sitting there, waiting for me to kiss her. I must have waited too long, for she opened one eye and said, Are you going to do it, or what? I will, I said. Just close your eyes again. Once she was back and waiting, I leaned forward slightly, wetting my dry lips with just one lick. I kept my eyes open until just before contact, not wanting to risk missing entirely and landing one on her nose or something. My puckered lips brushed against hers, pressed in, and then pulled off. Okay, she said afterwards. Not bad, but you were a bit too stiff. You should try to pucker a little less. Relax. It was like kissing. she smiled a little at what she was saying. Well, like kissing my brother. Were supposed to pretend, right? Sorry. Its okay. Just okay, let me show you, close your eyes. I did as she asked and waited. Soon I felt her lips on mine, gently, and then sliding up a little, so that my upper lip was squeezed between her two lips. She separated again. See? Uh-huh. Want to try again? We did, two more times, and then she said, See, youre getting better. You could be a little more forceful, though. Now, if its going pretty good, you can try pushing your tongue out and going for a French kiss. I swallowed, and then leaned in again, and her lips parted slightly. I tentatively stuck my tongue into the gap, which caused her to open more, and I probed deeper until I met her own tongue. It was like some kind of electric connection. We kissed for maybe fifteen seconds before she pulled away. I think she was actually blushing a little. See, youre not bad at it, really. I think your main problem is confidence. Its okay to be a little aggressive girls like guys who are a bit aggressive, you know? I had known that, but could never bring that out in myself. And, well, theres one other thing. What? Well, thats okay for just kissing, but if youre actually really, making out with a girl you should be using your hands more. Where? Where you want. The girl will let you know if its too much, theyll pull away. We know what guys want, so most of us dont hold it against them for trying even if were not ready yet. She leaned back, bit her lip, and then in one smooth motion, pulled her shirt over her head. This time, she wore a bra underneath, a very soft pink, almost white. To my relief, she reached behind her and undid the strap. Id seen guys having trouble with the bra in so many movies that I was scared of fumbling with it myself. It was probably the exact type of thing I should have practiced with my sister given this opportunity, but I didnt want to look like an idiot. Once her bra slid off, I was looking at her tits again, much closer, staring really. They were beautiful, perfectly shaped. I wished shed let me touch them. Then I remembered what shed just said. I should be using my hands more. I slid a little closer to her and leaned in to try to kiss again, but this time I slid my hand up her belly and cupped her breast with one hand. As I kissed, I squeezed it gently, feeling for the nipple. We kissed more, several times without conversation in between, while I played with her boobs, usually one at a time. I was a little nervous, but there was something comforting about her, so I wasnt practically shaking like I was with Judy. I guess it was because she was family, strange as it sounds. I trusted her not to make my worst fears come true. My heart still beat like I was in gym class and my stomach fluttered, but it was a good fluttering. One time when she broke off, she tilted her head to the side and said, You can kiss a girls neck, too So I did, planting small kisses up and down. It wasnt as much fun as kissing her lips, my tongue meeting hers, but she seemed to like it all the same, letting out a soft Mmm. Suddenly, her hand closed over mine. I had my whole hand over her breast, palm on the nipple, applying gentle pressure, but she started pulling me down. I was disappointed, thinking she was pulling me away, and then suddenly I realized she wasnt pulling my hand away from her breasts as towards somewhere else She guided me to her shorts, but stopped at the waistband and kept moving repeatedly there until Id slipped underneath. I took the hint and slid deeper, down between her legs. It felt warm there, warmer than the rest of her skin, and I could tell when I reached her slit, not just from the feel, but also because my fingers suddenly got wet. I kept up kissing on her neck, down towards the breasts, while my hand slid over the folds in her pussy until it found the hole itself. It was just too tempting, and she all but told me that she might pull away if I went too far, but wouldnt hold it against me. I curled my fingers in a bit, and then, when she didnt resist, plunged them inside, the first time Id ever gotten that far with a girl. Krista made a soft noise of surprise, but didnt otherwise object. I cant describe what it felt like, because it wasnt like anything else Id felt on my fingers warm and tight, like someone was squeezing my fingers from every direction. I wiggled my fingers around, but it didnt feel like there was much room to maneuver. When I did, her thighs squeezed together a little too, trapping my hand. It felt good, like it meant she wanted me there. Even if she was thinking I was some hunk in her class, I could hold onto the fantasy. We kept it up for something like a minute after that, not talking. Finally, Krista spoke. Bobby? Are you hard now? I had been for some time. Yeah. So can I have my turn now? Turn at what? Practicing something on you? Getting your opinion on it? I didnt want to stop, but how could I refuse? Besides, I had to know what it was that was on her mind. Chapter Six Sure, I said. She unclamped her legs and I reluctantly withdrew my fingers and slid a little away from her. What exactly did you have in mind? A blowjob. Oh, come on, I said, unable to believe it. I know you know how to give a blowjob, you said so. Inside, a tiny voice was screaming at me, You idiot! If someone offers to practice giving you a blowjob, you say yes! You dont question, you just agree! But somehow that voice hadnt stopped me. Luckily, my sister didnt take offense. She spoke rapidly, looking down at her hands. Its just when I did it with Tommy I never made him cum. I could suck on him for an hour and he wouldnt squirt. But if I pulled out and used my hand he went almost right away. Blowjobs are supposed to be better than hand jobs, right? From what I hear. So Im worried I was doing something wrong. Maybe hes just secretly gay. She laughed a little at that. No, Tommy was definitely not gay. Well, I cant think of any other reason. I mean, youre not biting or anything are you? No, of course not! she cried indignantly. So are you going to let me do this or not? Of course. She looked at me, down at my pants, and it took me a second to realize that a blowjob would be much easier to accomplish if I had my dick out. I unzipped my pants and pulled them down, then looked about awkwardly. How should we do this? Lying down? Sitting down? You can stay where you are, she said, and got off the bed to kneel at my feet. My dick was pointed towards her. I could hardly believe it was happening. My sister looked up at me. Okay. Be honest. If Im doing something wrong, dont hold back 'cause youre my brother, okay? I nodded. I hoped she hadnt noticed the way my dick stiffened and jerked when she said the words youre my brother. With one hand, she grabbed onto my shaft, then leaned in and started licking the head. Certainly no complaints there, it felt amazing. She moved her head around the side of it, putting a tiny bit of pressure on it with her lips, lightly nipping at it almost, though without teeth, before she returned to licking dead center. I felt Kristas tongue stop right beneath my head, stuck all the way out, and then she suddenly bobbed her head forward, mouth open, and took me inside. She sucked on the just the head for a little while, then went down as far as she could before she ran into her own hand, which was still squeezing the base of my dick. It was thrilling, stimulating, perfect. I had no standard of comparison save my hand, but I couldnt see anything wrong with her technique. I reflexively gripped the edge of my bed. Oh, wow. She pulled back to just the head and curled up her lip in the cutest smile, and then went down again. Pretty soon she was pumping back and forth in a regular rhythm, and as I watched her head bob up and down, cheeks sunken in very slightly, I thought about how wrong what we were doing was. But not with guilt or fear, the wrongness itself was turning me on. I thought about all sorts of other wrong things to do, fucking her, cumming inside her, even getting her pregnant. I almost spurted right then and there, but didnt want my sister to think I didnt have stamina, so I forced my mind to other things schoolwork, baseball, what might be happening on my favorite TV shows, whether my sister might tell somebody, the shame and dirty looks and laughter behind my back if anybody did. That last one was too far in the other direction. I knew it, she said, pulling off. I knew I was doing something wrong. What? You got soft. No, it wasnt you I told you I wanted you to be honest. I was, I insisted. It wasnt you, you were doing great, it was just a thought that crossed my mind. What? I figured Id be honest. What sort of shit might happen if you told anybody about this. Relax. Nobodys going to find out, I promise. She waved my dick from side to side. Still only semi-erect, it flopped a little. So think of something hot so I can finish? I did, I thought once again of fucking her, in my bed, in her bed, in the bathroom, in our parents bed, in every position imaginable. I imagined cumming all over her and then inside her. It was good enough, my cock stiffened with renewed vigor and jerked with the impossible hope that the fantasies might someday come true. Krista went back to sucking on me, and, as though she doubted my word that she wasnt doing something wrong, put even more effort on it, her tongue, inside of her mouth, slid around me. A couple more minutes of that was all I could take. My balls felt like they were coming to life, ready to go into production, and I was starting to feel that extra stiff sensation in my dick. I figured I should warn her. Okay, Im about to cum. I tried to reach for my tissues with one hand, but they were a little too far. If she pulled off it might be a big mess. Luckily, that didnt happen. She just made a Mmhmmm sound to show she heard, but kept right on sucking. When I was just about to blow she retreated so that her mouth was on the head of my dick, and her cheeks collapsed again. A wave of pleasure rushed through me, making most of my muscles tense in anticipation of feeling it, and then a jet squirted out of me and into her mouth. I couldnt see it, but I knew thats what happened. And my sister swallowed. Six or seven jets went out of me and down her throat. When I was down to a dribble, she pulled off and let me go. So, I guess it was good? Yeah. I took a deep breath, then another. I think theres only one explanation for why Tommy didnt cum. She looked up at me, eyebrow cocked. Hes definitely a fag in denial. No straight man wouldnt cum from that. She giggled a little. Trust me, hes not gay. You said you never went all the way with him, right? I said. That proves it. Even if by some miracle he didnt cum from that blowjob, it would only be because he wanted to fuck you. Any straight guy would do everything possible to fuck you. She smiled, then teased, Youre a straight guy, arent you, Bobby? What exactly are you saying? My smile was uneasy, because the tease was too close to the truth. Well, any straight guy whos not related to you. And even then. No, it was best to get off the subject. I was pushing my luck as it was. So what was it that got you hard, then, after we had to stop for a sec? Since you werent thinking about me? I blushed a little, turned away. I dont know, I guess I was just thinking of pussy. Then I decided to go a step farther, somehow I didnt fear her judging me as much, I guess it probably looked a lot like yours. But only because it was the closest real one Ive seen. Its not that mysterious, you know, she said. Its just a crack. Its not the kind of thing where a guy would she stopped suddenly, and laughed, before continuing, lick it for an hour just to get a closer look. I blushed a little more, remembering Id used similar words. Some guys would. I would, but maybe not just for the look. What for then? To make the girl feel good. Thats an important skill to have. And its something else I need practice in. Chapter Seven Krista raised her eyebrows. So you want to practice that sometime? Her voice seemed to raise in pitch a little, like she was surprised, or even hopeful. Sure. Weve still got time before Mom and Dad get home. But, youve already cum I was confused. So? So, guys hate doing that. The only reason a guy does that is so youll do something back. But if theyve cum, they wont bother. What? I shook my head. Is that what Tommy did to you? She shook her head. Just what I hear from friends. Tommys never licked me down there. Actually nobody has. Guys just think its gross to do that. I shook my head in wonder. The evidence for Tommy being a closeted fag is only increasing. I didnt really know if eating a girl out was gross or not, having never done the deed. Id heard people say it was, that it tasted like strong fish, but Id also heard people say it wasnt at all, that they even enjoyed it. The one thing I did know was that girls were supposed to like it, really like it. And if youre like me, full of self-doubt about your own abilities in other areas, you dont want to shy away from something that supposedly makes a girl cum better than anything else. If I could somehow get good at it, it would be like a secret weapon. Even if it really was gross, I imagined I could fake my way through it. Fish wasnt so bad. Ive never done it either, but Id like to. Even now. Now she was blushing and looking all over the room except at me. Okay, she said as she got to her feet. If you really need to practice it, I guess we can start now. She dropped her shorts quickly, then, more slowly, the pink panties beneath them. Id already seen it so I didnt know why she felt she had to tease, waiting a few seconds before the final reveal, but maybe girls are just built that way. It wasnt long before they were gone, and she climbed on the bed. She removed her socks and looked at me. So, on my back? I nodded, got out of the way so she could stretch out, and then went to the foot of the bed so I could rest myself there. She lay back, looking at the ceiling, but her legs were spread slightly. I lowered myself down between them, my face right in her crotch. It was even more beautiful close up than it was when Id seen it the other day. It seemed to glisten a little, the light hitting her wetness just right. I didnt detect any smell except a little bit of sweat, but it didnt smell bad, like B.O., either. I took in a deep breath, and the scent, elusive, faint, seemed to escape from my lungs and go straight into my heart, causing it to flutter a bit and pump faster on this strange new fuel. I took an experimental lick, from the bottom of her hole to the top of the little nub, and Krista shuddered violently in surprise. Is that okay? I asked, suddenly freaked. Her voice seemed a little weak and wavering. Yes, she said. I just wasnt expecting it. She was quiet for a moment, and then added, You can keep going, if you want. It didnt taste bad. It didnt taste like much of anything, like licking bare skin, almost, but there was something in the not-taste of it that was arousing all the same, so I took another lick. I spread her lips aside with my fingers and licked the edges, and then, trying to imitate what Id seen on videos of the Internet, flicked my tongue from side to side rapidly. Kristas mound rose and fell in undulating waves, she must have been flexing and releasing her butt to pull that off, but since it looked like she was trying to meet me, I had to assume she was enjoying it, and kept up my work. I tongued around the clit and then went down to the hole, which seemed to have a faint metallic tang to it, but nothing too unpleasant. It had been a while since Id last seen a porn movie, but I remembered guys, or girls, usually used their fingers too, so I stuck a couple in her hole while I licked closer to the top of the slit. A few minutes in, my tongue started to get tired, but Krista, who had been whimpering softly in pleasure, was bucking more and more against me. I wasnt about to give up if I sprained my tongue, so be it, at least Id have done so in a good cause. I realized I could give my tongue a little bit of a break by focusing more on my fingers and using my lips to kiss her softly and even provide a little bit of suction. She yelped out a little when I tried to suck on her clit, and I looked up at her. Was that bad? She spoke through deep breaths. No, it was good, but too much. Its too sensitive there. I took the advice, figuring it might be like the head of my penis. It felt great, but too much pressure right on it was just too much but then, at the right time, it was made it so much better. So, I waited, keeping it in reserve, licking her in other places and keeping up a steady motion on the inside with my fingers. Soon, she began to speak, urging me, Keep going. As though I was planning to stop. Keep going. Thats it mmm. She seemed to be clenching more and more, both her ass, so she grinded up into me, but also inside, on my fingers. I figured she was close, so I returned to her clit, and kissed on it, letting just the top of my tongue through to tease it. Oh god Krista cried out, and rose once more into me, practically shoving her cunt into my face as she let out a wordless cry. Then she dropped, and was still, and she let out a deep, content breath. So, how was it? I asked. That was great, she said finally. I never thought it would feel like that. I dont think you need. She trailed off. I mean, it was awful, Bobby. Just horrible. I think you need a lot more practice on it. She sighed. I guess I can help you out with that though, since theres nothing else to do in this house without all our electronics. I grinned, not taking her seriously. Okay. Thanks, Krista. I really want to get it right, as long as it takes. We didnt want to risk anything else, because our parents would be home soon, and I guess we were feeling a little awkward around each other again, being naked around each other even after wed both cum, because she dressed and went to her room and I stayed in mine. After a good half hour of lying on my bed, staring at the ceiling and savoring the memory of what had just happened, I started looking for something else to do. Eventually, I chose homework. On a Friday. I was that bored. If only Mom knew that taking away everything fun left us nothing to do but homework and incestual oral sex with each other, she never would have started us on this challenge. Chapter Eight The next morning, I woke up to a knock at the door. What? It was Dad. Your Mom made breakfast itll be ready in a couple minutes. I groaned, looked at the time, and groaned even louder. It was eight in the morning. Moms crazy plan was bad enough, but we couldnt even sleep in on weekends? Now, now, I heard my Dad say through the door. Its not like you stayed up very late last night, you got plenty of sleep. It was true. I usually stayed up until at least one or two on Friday nights, but not last night. Theres just not much point to being up past dark when the only thing youre allowed to do is read. Theres a principle at stake here, I yelled. Teenagers are supposed to be able to sleep in on weekends. Just be thankful I talked her out of waking you up to help. Be down in five minutes or shell probably break down the door. I grumbled and got to my feet to dress. Five minutes later, I was eating an omelet. My sister speared a breakfast sausage with a fork and stuck it in her mouth, catching my eye. I shifted uncomfortably in my seat. Neither of my parents seemed to have noticed, absorbed in their own meals. After she swallowed her bite, Krista asked, So, whats the big family togetherness plan for today? Please God dont let it be another board game, I muttered, loudly enough to be overheard by everybody. Friday night wed spent playing Pictionary. Sure it was fun but I was starting to get sick of board games. Actually, I was way past sick of board games. Theres nothing wrong with board games, Mom said. Theyre a good, healthy activity for building family bonds. If you want us to do something together, we could all play the same video game, I suggested once again. There are plenty of games that we can all play as a family. I knew it was hopeless, but I wanted to keep making the point that I was not enjoying these stupid restrictions. Staring at the same screen is not family togetherness, Bobby. Mom said. You may scoff at it, but I happen to think this challenge has already brought us all closer together. I agree Mom, Krista piped up. So, does that mean we can stop? Mission accomplished? Nice try. She put her fork down and folded her hands in her lap. I was thinking, since its such a nice day, we could go to the park and have a picnic. Throw the Frisbee around, fly a kite, maybe even play volleyball. 2 on 2, what do you say? Yay, I said unenthusiastically. Sounds like fun. Dad buttered a slice of toast and said, If were going to do this, we should buy groceries, so we can make lunch. The pantrys getting pretty bare. Unless you want to just buy hot dogs at the park. No, Mom insisted. No fast food is one of the rules of the challenge. So well go to the grocery store after breakfast. We can all go together. I sighed. Do we have to? Were supposed to spend time as a family Family togetherness might not mean a lot to you right now, but when youre older youre going to thank me for forcing us together. Dad spoke up on our behalf. Dear, theres no reason to drag them along if were spending the whole day together afterwards. Im sure theyve still got homework to do anyway. Mom seemed mollified. Oh, all right. After breakfast I tried unsuccessfully to suggest things like chips, cookies, energy bars, and the like to add to the shopping list, while Krista went off to take a shower. I took one after her, and then hung around the living room reading a book assigned for school. Mom and Dad passed by on their way to the door. Okay, while were gone, Ive got a job for you both, Mom said. I rolled my eyes. Try to think of one fun thing to do today. I dont want you moping around, rolling your eyes like that at everything at the park. Try to think of something thatll put a smile on your face. I rolled my eyes at that again, and went back to the book. Mom sighed, and left. Krista sat down on the chair nearest the window, gazing out. Okay, theyve pulled out of the driveway, she said. Theyre gone. So? She grinned. How long does it take to do the grocery shopping? Saturday was the craziest shopping time, and Mom and Dad usually took a long time with it. My Dad liked to find the best deals for everything. My Mom usually tried to buy the healthiest things with the fewest preservatives. I dont know, about an hour. Right, she said. She took my hand. That means you can get an hour of practice in at eating girls out. Unless youd prefer to just sit here and read. She tilted her head to the side and grinned impishly. Mom said to think of something to put smiles on our faces. I allowed her to pull me away towards her room. Once there, she took off her clothes and lay on the bed, beckoning me over. I lowered myself between her spread legs and buried my tongue in her slit. Freshly showered, she didnt smell quite as sweaty, and there was an underlying hint of coconut, probably from her body-wash. It wasnt bad the first time, but this time it was practically a pleasure. I was just getting into it when she spoke. Hey, Bobby, I was thinking, this idea of practicing with each other? Its mmm its working out pretty good, right? Yeah, I said. Too bad we didnt think of it years ago. I wiggled my tongue in the space between her clit and her pussy wall. Oh, God, yeah. She took a breath. So, do you think sometime you might want to take it the rest of the way? I stopped a moment, looked at her. What do you mean? I thought I knew, but it was too unbelievable. Youre a virgin. Im a virgin. So we can practice sex on each other. That way when we do decide to lose our virginities, well already know exactly how to do it well. Uh, how exactly do we practice sex without losing our virginities? It doesnt count when its with family. That wouldnt make sense, would it? That would be like saying youre not a virgin because you fucked your hand or Im not because I used a vibrator. I didnt quite agree with her logic. I didnt think anybody in their right mind would. Kristas claim to being the normal one in the family was slipping. But my dick told me not to argue the point, and this time I listened to what it was telling me. So you think we should fuck? Maybe, sometime. Until we get good enough at it to do it with others. I dont mean right now its just I dont know, an idea. If you were interested. She put a hand on my head, pushing me gently towards her snatch. Just think about it. But in the meantime I took the hint, and resumed my licking while I thought about what she said. It didnt take much. I wanted to do it. I wanted to fuck my sister. I wasnt sure it was the right thing to do, but what wed already done wasnt either, and it would certainly help to get through the Unplugged Challenge. I shoved two fingers into her, imagining it was my dick, thrusting in and out. A few minutes, and an uncounted number of kisses on her pussy later, I spoke. Ive thought about it, I said. I think youre right. As long as were just pretending were with different people, and youre on birth control, I dont see anything wrong with it. My biggest problem was that I was almost certain I wouldnt be pretending I was with anybody else. I hadnt been with anything else wed done. She grunted. Okay, then do it. I looked up at her, gaping, unsure I heard her right. Right now? Yes. I changed my mind. Why wait? Chapter Nine I stood up rapidly, wanting to get undressed before she changed her mind again, and she pulled herself into a lounging position instead of lying on her back. I flung my shirt aside and it landed briefly on her dresser before sliding to the floor. My pants and boxers I just dropped directly on her carpet, then half-walked, half-hopped to the edge of the bed. Krista scooted her butt on the covers to meet me, legs bent and out of the way. I guided my cock to her pussy and she used her hands to spread it open. I didnt think much about what I was about to do, other than the sheer want of it. Id been a virgin 17 years too long. No longer. The head of my cock touched the edge of her hole, and she shivered while my dick twitched and let out a little precum. I didnt want to wait any more, so I pushed in, slowly but without stopping. Before long, I was all the way inside her. I looked down at the union between us, and then at my sisters face, suddenly worried that I might be hurting her, or worse, that shed changed her mind at the last minute. She stared back at me and smiled, dispelling my fears, and moved her hips back and forth as though to give me a hint about what to do next. I took that hint and pumped in and out, at first just a slow sawing motion nearly all the way out and then back in, but very soon Id moved up to quick thrusts as I supported my weight with my hands on her bed just beside her shoulders. It certainly beat my hand, was superior even to her mouth, but that might have just been that I knew I was not only fucking but fucking my own sister. The little grimaces she made as I slammed into her were beautiful, at least once I got over the fear that they were from pain. If it was from pain she wouldnt be rocking back against me, she wouldnt be telling me more in a breathless voice. We changed positions, once, after I slipped out of her with an over-enthusiastic pullback. After an initial off-centered stab to get back in, Krista drew her legs back and pulled back on the bed. What? I asked, the old fears returning. Something wrong? No, I wanna try another way. Sit down. I fell to the bed beside her, and we shifted together as she crawled over me to straddle near my waist. With one hand she reached behind herself and grabbed my dick, centered it, then fell back, sinking all the way down. Once we were fully coupled again, she started to move, even more energetically than I had. My hands settled on her thighs at first, but then after a while I rose up and squeezed her tits for a while. That wasnt enough for long and I took one of her stiff nipples in my mouth and began sucking on it as she moaned. As much fun as it was, I decided I couldnt let her do all the work so I pistoned my hips up and down. If she wanted to ride me, I wanted it to be a ride to remember. I even rubbed the top of her pussy a little with my thumb for a bit more stimulation. I heard a noise, but disregarded it, figuring that the force of our movements had bumped the bed against her night table and knocked something over. It wasnt important. What we were doing was almost all-consuming. It was a wonder I hadnt cum I guess it was my subconscious at work, I was so concerned that I leave a good impression that I wasnt relaxed enough to actually climax. That wouldnt protect me for long, though. Mostly, while we were in this position, Krista had kept her head pointing upwards, looking at the ceiling instead of at me directly. That changed suddenly. For no reason I could figure out, she slowed the pace of her bouncing and looked me in the eyes, drew closer. Our mouths touched, a gap formed, and our tongues met in the middle, played together, while we rocked together. The kiss broke, resumed, broke again, resumed again, and then the next time she broke it Krista began riding up and down again like a woman possessed. She closed her eyes, and was whispering softly. Yeah, fuck me, show me you love me too. I guessed she was deep into fantasy mode, now, pretending I was some guy she fancied. I didnt answer in words, not wanting to break the spell, but struggled to keep up the motion. The bed began to creak beneath us, like it was unable to withstand the force. Yeah, thats it, fuck me, fuck me, give me all youve got, Bobby. It took a little while to sink in that shed used my name. Did that mean the guy she was imagining was me? Or did she just slip out of the fantasy a moment? I didnt know, but I preferred the first idea. So, when she next spoke, I decided to answer. She asked, Do you like fucking me Bobby? Yeah, I love fucking you, Krista. I love you. My face curled in an involuntary wince, worried it would make her freak out, but it didnt, she kept moving and buried her face in my neck. She kissed me up and down. It was intoxicating, freeing. I began to lose myself, my inhibitions, my fears about my performance, everything, determined only to give her all I had. Mmm... me too. You going to cum? Pretty soon. Go on, cum inside me. I almost did, then, but I had a little more fight in me so I gave it all I had, putting all my energy into the finish as Krista made sharp cries of pleasure. She was close, and if there was one thing I wanted more than to empty my load inside of her, it was to make her cum first. Our combined movements rattled the bed and every so often another creak would ring out. That was where everything turned on its head. Wouldnt you know it, the one time Im not neurotically paranoid about the littlest things, obsessing about all the possible ways things could go wrong, is the time it bites me in the ass. If I hadnt been so wrapped up in the passion of the moment, I might have considered that Mom might not spend as much time shopping if she was only buying fresh fruits, vegetables and meat, instead of pre-made meals, that she might have gone to a nearby vegetable store with a butcher right beside it instead of driving all the way to the grocery store. If it didnt feel so damn good to have my sister bouncing up and down on my dick, I might not have dismissed that noise as probably nothing, I might not have been on the verge of cumming and unable to stop when I finally realized that some of the creaks werent from the bed, but were from the stairs. Oh my god, my Moms voice rang out a second after the door swung open, but it was too late. I had just squirted a load in my sisters pussy as she cried out. Both of us stared, in shock, at the door. It was impossible to hide what wed been doing. We were all frozen that way, the three of us, while my Dad started up the stairs, drawn by my mothers shout. As he looked at the situation, his eyes widened, and he even drew back, reeling a little. Not much, just a fraction of an inch. It was still probably the most surprised Id ever seen him. He was frozen too, unsure what to say. Finally, as my cum started to leak out of my sisters pussy, he had his answer ready. Well, Lorraine, you said you wanted the kids to be closer. Well done. Mission accomplished. END Click to expand... again this is a work of fiction. Leave comments if you enjoyed the story, as he appreciates feedback.
