She was a year ahead of me and it wasn't planned exactly for me to follow her, but the university in question happened to be in a convenient location just far enough away that we'd be out of our parents' immediate reach. Far enough that we'd be living in the dorms on campus rather than at home. What was perhaps more of a coincidence was that we ended up in the same dorm, although on different floors. I didn't mind and I didn't think my sister did either since, despite being in the same building, we could easily go days without seeing each other if we didn't want to. At the same time we were close enough that we could be there if the other needed something. In some ways it was an ideal setup. We ran into each other somewhat frequently as it turned out, but mostly we left each other's rooms alone. It was a couple months before the first time Zoey purposefully came to visit me. I couldn't say I was expecting it to be her when I heard the knock on my door that evening. "Oh, hey," I said after opening the door and finding her standing there. "Hey dude," she said. "Listen, if you're busy that's cool but if not can I hang out here for a while?" "Sure, if you want. I don't exactly have a lot of space...." "That's fine. I don't have that much space either and your room has the advantage of not having a sexually active roommate in it. Like, currently sexually active." "Your roommate's having sex in your room?" I guessed, based on the rather blatant hinting. "Yeah. Which is fine, and I don't mind letting her have some fun in there, but it's been getting harder to think up ways to occupy myself. Sometimes I just don't feel like going out you know?" "I understand. I guess I don't really have that problem." "No I know. Lucky bastard, getting your own room." "That's what happens when you put more effort into your scholarship applications and shit." "Whatever. Nothing I can do about it now." Zoey sat down on my bed while I resumed my position at my desk. It really wasn't bad for a dorm room, though it was typical enough in it's lack of space. I'd had some trouble even getting my tv to fit without blocking off something I'd need to get to, but there was no way I was going to go the whole school year without my video games. I assumed my sister would watch a movie, or maybe play some Mario Kart since that was pretty well the one game she actually admitted to liking. Instead of amusing herself though she just sat there for a couple minutes while I worked on some stuff for my classes. "So how's it going so far?" she asked. "I mean the whole living on your own and your classes and everything." "Wow, you are bored aren't you?" I said. "Partly. I'm also looking for a distraction. I kinda accidentally walked in on my roommate and her 'boyfriend' right before I came up here. They weren't wearing quite as many clothes as I would have liked." "Ooh, yeah. Rough. Is she hot?" Zoey tilted her head and gave me a crooked smile. "If I say yes are you going to go down there pretending to look for me? Actually don't answer, I don't want to know. But yeah, I think you'd like her. I'll maybe introduce you sometime." "And if she didn't already have a boyfriend I might be excited about that." "Good point. But as far as I can tell they aren't serious, it might not last that long anyway." **** It turned out that Zoey was wrong about her roommate's relationship to some extent, as I found out next time she came to see me. It had probably been a couple weeks, though I wasn't really keeping track. "She having sex in your room again?" I asked, assuming I'd get a yes and that would be it. "Actually no. She, well, I guess they broke up. Or he broke up with her or something. She's taking it kinda hard." "Oh. So you're just avoiding that then?" Zoey gave me a dirty look. "Yeah, 'cause I couldn't possibly be trying to help. I'm just completely self-centered. Jerk." "I didn't mean that, it's just that you're here and not, you know, with your roommate. That's where I would have expected you to be is all." "I was. Now I need backup. She's doing the whole 'no one's ever going to love me again' thing and I can't seem to get through to her." "How am I supposed to help? I'm way worse at this kind of thing than you." "All I need you to do is pretend to be into her, or actually be into her if you want, so she cheers up." I rolled my eyes. "Yeah, because that'll go really well if she finds out that's what we're doing. I'm pretty sure it's going to make things worse. Possibly a lot worse for you since you'll have a roommate who hates you." Zoey sighed and flopped down on my bed dramatically. "So what do I do? She'd driving me crazy. And I want to help, but I can't." "I don't know, but I think you understand as well as I do that if you try to manipulate her it could backfire really badly on you." She thought about that for a minute while I simply tried to figure out how to stop her doing something stupid. "Okay, how about you just go on your own?" she suggested. "Pretend I never even talked to you about the problem. Hell, you can even pretend to just be someone from one of my classes or whatever, she wouldn't know the difference. Say you need to borrow my notes maybe." "Well, that's a little better. Except it means she'll figure it out if she ever catches us together and we forget to act properly." "What are the odds? The two of us talk maybe once every week or two. It'll be fine." I still wasn't convinced, but I was giving in and Zoey could tell. She had a lot of experience persuading me to her way of thinking. "I guess... maybe I could just go down there and see what happens. I might not even have to try anything and I could just come out and tell her I'm your brother." "Whatever seems best," Zoey agreed, not doing a very good job of hiding her satisfaction at winning. "I'll wait here." **** It wasn't a long way to my sister's room, but it was long enough for me to regret giving in to her. The more I thought about it the more I realized I had no idea what to do once I got there. I couldn't go back though or Zoey was just going to tease me about chickening out. Ditto for abandoning the plan altogether and finding somewhere else to be. All I could do was carry on and hope I came up with something. Even as I knocked on the door I was completely blanking on what to say when it opened. "Hello?" The door swung about halfway open to reveal Zoey's roommate, and my first impression was that my sister hadn't been kidding about how she was taking the breakup. The girl in front of me, partly hidden by the door, was definitely the sort I'd find cute, maybe even hot, under normal circumstances. Circumstances where her hair wasn't a mess and she didn't look like she'd been moping around in her room all day for instance. "Um, hi," I said. "I'm Adam. Zoey's brother." "Oh, hi. She's told me about you. She's not actually here right now though, she said she had to meet someone. She might be back soon though." "Okay," I said, mentally cursing myself for immediately giving away my identity. I might have done so anyway, but it would have been nice to at least test out some different ideas first. Still, I was under too much pressure to be all that hard on myself. "I, uh, it's none of my business really, but are you alright?" "I'm..." she started, trying to put on a fake smile before giving up. "Actually, no. Not really. I just had kind of a rough breakup." "Oh, I'm sorry." "Thanks." She took a moment to study me. "I'm Mara by the way, I guess I didn't say that yet did I?" she said, belatedly extending a hand to me. We shook hands a little awkwardly, but I did notice at least a small upward curve on her lips. It could easily have been nothing though. "Nice to meet you," I said. "I wish it could been when I wasn't such a mess," she told me. "But yeah, nice to meet you too. I really don't know when your sister's going to be back, she just said she was supposed to meet up with someone for an assignment or something and she had to go reschedule. Something like that. You can wait for her here if you want. Or I can just tell her you stopped by if that's easier." Of course I actually did know where Zoey went, though I wasn't entirely sure how long she'd be either. It wasn't a hard decision to wait until she showed up again since that had been the plan to start with. "Yeah if you don't mind me hanging out for a few minutes that'd better I think," I said. "Not that it's all that urgent if you're just being polite and would rather I went...." "No seriously," she said, waving off my concern, "I'd actually rather have someone around right now. Keeps me from thinking too much." "Fair enough." I entered the room that was bigger than mine, but of course it was meant for two people instead of just one. It still wasn't anything I'd call spacious and I could see how there would be nowhere near enough privacy for my sister to be able to ignore it if her roommate was having sex. "So, uh, were you guys together long?" I asked, awkwardly steering the conversation back to the subject I was supposed to help with. "Not really I guess," Mara said. "Not long enough that it should be bothering this much, we never really got as serious as I wanted. I think maybe I liked him more than he liked me." She gave me a weak smile and sat down on her bed. I debated taking the other bed, but they were just far enough away that it felt silly so I sat down beside her, though not too close since I didn't exactly know her that well. "That does kind of suck, but if that was the case maybe it's better that it happened now and not later," I said. "Could be. But now I just keep wondering what's wrong with me, you know? Like was there something about me he just couldn't stand or something. And if I meet someone else is it going to happen again and--" "Look," I interrupted, "I mean we just met and all, but I really don't think it was your fault. Zoey told me a little about you and...." I shrugged. "I guess I don't know what I'm getting at. But I think you'll be able to find someone else, someone who really likes you, and it'll work out even better." "You think?" "I don't see why not. Like, you're obviously ho-- I mean, you're not unattractive or anything," I said, suddenly feeling out of my element. I wasn't one much for knowing how to compliment girls I'd only just met. "See, normally I'd find that sweet except I know I look terrible right now so you're clearly just trying to make me feel better." "I'll admit it's not a great look for you, but I wouldn't say it's terrible." "Uh huh? And what would you say it is?" Without visibly moving Mara seemed closer to me than she had been. I tried to lean away a bit without being obvious. "I don't know. But, you know, if it was a more normal day for you or something... like if...." She was definitely leaning toward me now and looking far more sure of herself than the sad girl who'd met me at the door a few minutes ago. At the same time, I was becoming decidedly less comfortable with the situation and unsure what I'd managed to get myself into. "Do you have a girlfriend Adam?" "Um, not so much." "Then you'd better tell me now if you didn't really mean what you told me," she said, her voice lowered almost to a whisper. "I...." I swallowed hard and accepted the inevitable as she got close enough to kiss me. Not that I tended to mind if a girl wanted to make out with me, but the situation was a bit on the weird side. I almost felt like I was taking advantage somehow, even though I'd had no intention of doing so and she was the one making a move. Truth be told it was hardly unpleasant, not that there was any particular reason it should have been, and I found myself relaxing and just enjoying the experience. There was even something about Mara's bedraggled look that was working for me now that she was showing enough confidence to make it somehow sexy. And if she had that confidence that was a good thing right? That was what I was supposed to accomplish here, or something like it anyway. "Probably shouldn't be doing this," Mara said as she climbed nearly into my lap. "Well you-" I said, getting cut off quickly as her lips closed on mine again. She was most likely right about it being a bad idea in some ways, though I couldn't for the life of me figure out what they were at that particular moment. I had a girl on top of me aggressively kissing me and pressing her breasts against my chest; it was the sort of thing that could easily derail my thought process. "Zoey's gonna kill me," she said. "Jesus, her little brother. She's not gonna like that." Despite Mara's words she didn't seem to be too worried. I, on the other hand, was once I remembered that Zoey could show up at any moment. As though summoned by my thoughts, the door to the room opened to reveal my older sister just as I started thinking about what I was going to do if she showed up. At first she just looked confused, but that didn't last long before turning into something less neutral. "God dammit," Zoey said. "I leave you alone for a minute and...." She gestured at Mara and me, allowing us to make her point for her. "Sorry," Mara said. "I know I shouldn't have... well it just kind of happened." "Here I was planning on helping you get through your breakup and everything and it turns out you can manage that just fine on your own," my sister continued. "I actually thought you were taking it hard but you can't be that broken up over it." "Hey! Look I shouldn't have jumped your brother like this, I know that, but it's only 'cause...." She shrugged. "Okay I don't know why. But it helped, I seriously was in bad shape." Zoey sighed and sat on her bed. "Could you at least get off him," she said. "At least wait for me to leave again if you insist on doing that kind of thing." "Zoey," I said, feeling like I had to add something at that point. "I didn't mea-" "Oh I don't blame you," she said. "Neither of you, not really. It's not like I should expect anything different at this point. I should be used to walking in on something I don't want to see by now." "What's that supposed to mean?" Mara interjected. "You have a problem with me having sex in here, is that it?" "Well yeah, since you bring it up. It's my room too, I'd like to be able to use it whenever I want and not work around your schedule." The argument had taken a different turn and left me behind. I started seriously eyeing the exit, particularly when Mara climbed off me and made escape a more viable option. "Have you seriously been upset about that?" Mara asked. "Why didn't you say anything?" "Oh yeah right," Zoey said derisively. "What, like ask you not to have sex in here anymore? I'm sure that would have gone over well." "Well we could have at least talked about it, and we've had to talk about other things so I know you're not too shy to say anything." Mara crossed her arms and looked contemplatively at my sister. "You know, there was this suspicion I had at one point, but then I forgot about it. Didn't think much of it. Except now it makes more sense, and it would explain some things." "That so? What's your 'suspicion' then?" "I think you're jealous." Zoey laughed, but hesitated a second too long before reacting to make it convincing. "Jealous of you?" she said. "Me or my boy... ex-boyfriend, whichever. Maybe both of us. How long has it been since you've had sex?" Mara pointed an accusing finger at my sister who rolled her eyes but didn't have an immediate comeback. For my part, thoughts of escape were being replaced by a morbid curiosity as to where the argument was headed. Like I was watching a figurative train wreck. "None of your business," Zoey said. "Well it kind of is," Mara said. "I'm your roommate and I have a certain amount of interest in keeping you happy. At least happy enough that you don't murder me in my sleep." Mara was slowly getting closer to my sister as they spoke, much the same way she'd done to me. The main difference being that she pushed Zoey onto her back before climbing on top of her. Even as I watched her do it though I still didn't manage to catch on to what exactly she was up to. Probably because it didn't even register as a real possibility. "Okay, now I'm just confused," Zoey said. "I'm helping," Mara explained. "You need to get laid, I think we'll all fell better once you do." "Oh come on!" My sister unsuccessfully attempted to push her roommate off. "You're being such a goof, I'm not even into girls." "Mm-hm, I'm usually not either. It's a good time for experimenting though isn't it? University's a popular place for that sort of thing as I understand it." "Whatever. Still not interested." Zoey made another bid for freedom and once again was held down. Mara must have been stronger than she looked since my sister was used to dealing with me and shouldn't have had any trouble with the situation. "Look, I'm your option right now, 'cept maybe for your brother," Mara said, nodding toward me. "But I don't think you'd be into that. If you are though...." "Ew, come on don't be gross. And get off me already." I understood where the sentiment was coming from, yet it still hurt a little when Zoey expressed her disgust at the thought of me and her in some kind of sexual situation. My instinctive fear of disapproval surfacing despite me knowing that it wasn't really anything I should be worried about. "I don't think you really want me to get off," Mara said. "At least not in that sense. You haven't been fighting me nearly as hard as I think you could manage if you felt like it." I couldn't see all that well, but Mara definitely looked like she was doing something to my sister with one of her hands. Some kind of rubbing motion. Her body blocked me from seeing any more than that without moving. Whatever it was, I was once again feeling like a swift exit might be in order before too long. "Come on," Zoey said in a much less defiant tone. "Adam's, like, right there. Can we just drop this for now?" Mara turned her head to look at me. "He is right there, isn't he?" she said thoughtfully. "Um, I can just, you know, go now," I said, taking that as my cue to leave. "You could," Mara agreed. "Or...." "No," Zoey said flatly. "You didn't even hear what I was going to say." "I don't need to. Besides, he'll say no anyway." "Well then let me at least ask him. I mean, you said you wanted to help me over the breakup and everything right? This would totally do it." Mara turned to me again, and I got the feeling that I too had an idea what her question was going to be. "What do you think Adam, you wouldn't mind fucking me would you? No strings attached." "Well... no, I wouldn't mind," I said slowly. "But you mean, like, right now?" "Yep. Come on, a brother and sister at the same time? That'd be amazing. And Zoey I promise there'd be no more moping around from me," she said, as though it was enough of an incentive. I finally forced myself to move and started to leave the room, knowing that I really, really needed to get out of there before things got any weirder, and as I did Mara's body no longer completely blocked off my sister from my line of sight. The first thing I noticed was the expression on her face was not one of someone being forced into anything, not nearly to the extent she was pretending at any rate. "Yeah, I'm sure that'd be worth the permanent emotional scarring we'd get out of it," Zoey said. She looked at me as though she expected me to either leave as I planned to, or just say no, or... something. She seemed to actually be waiting for me to make the official decision and somehow that realization stopped me from acting. Unintended Results "You wouldn't even have to look at each other you know," Mara said, sensing weakness. "I'd be between you, and you can close your eyes the whole time if you want. It could be anyone else there for all your body'll know the difference." "We'll know better," Zoey said, but she spoke even less convincingly than she been up until now. "Free pussy 'til you cum, then you can leave and not even worry about me," Mara said to me, knowing that I was the one who needed that last push. "You must like that idea at least a little." She wiggled her butt at me and winked. Normally I wouldn't have liked the thought of using a girl like that, but this was not a normal situation. And at some point I'd started getting hard without fully realizing it, no doubt affecting my judgement somewhat. "Tell me to go," I said, looking straight at Zoey. "Tell me to leave right now." "Adam...." "Seriously, do it." I stared at my sister who stared right back, a staring contest for higher stakes than I'd ever played for before. Eventually she looked away and I knew she couldn't say no, nor could I without her help. I shifted my gaze to Mara who had been watching with interest and she understood without any words being exchanged. "Alright, scootch over a bit," Mara said to Zoey. "Make some room for your brother." Zoey was going to hate me for this, I felt certain of it, but dammit she wouldn't say no when I needed her to so it wasn't all on me. The bed wasn't that big and normally would have been an issue for more than two people, but I wasn't planning on taking up any of that space. Mara was on top of Zoey and I could tell she had a hand down her panties at this point, but my only concern was the ass being presented to me. I ignored Mara's hint to join them on the bed and instead positioned her so that she was in more or less the right position for me while I remained standing. Less chance of accidental contact with Zoey that way. Mara's jeans posed a minor challenge to me: she was in an awkward position to remove them, and she wouldn't stay still for more than a couple seconds at a time. They didn't need to come all the way off though, just down far enough to give me access. Once again, this was not how I would have liked my first time with a girl to go, but she clearly wasn't in the mood for any kind of romance and having my sister there didn't put me in the mood for it either. There's the cliche of guys always thinking with their penis, and in this instance it more or less fit. Most every other part of my body was telling me I was going to regret it. "Mmm, yeah. Put it in," Mara told me. "Just fuck me while I take care of your sister. Everyone wins." Including a therapist or two somewhere down the road no doubt. Zoey was staying conspicuously silent, except for the sound of her breathing and the occasional small gasp. Whatever Mara was doing to her it seemed to be working, not that I wanted to think about it too much. I finally got Mara's jeans pulled down sufficiently for my purposes, with more fumbling than necessary thanks to her inability to help even a little. Her panties were much easier and were practically trivial in comparison, however I had to touch them enough that I could hardly fail to notice the damp patch on them. Apparently she really wasn't kidding about liking the idea of having a threeway with siblings. I winced slightly as the thought of how close my sister was inadvertently went through my mind, but quickly put it to one side. The faster I moved, the faster I could get out of there. Mara's pussy was indeed wet enough to allow me entry, as I confirmed by probing the area with my fingers. Even though I hadn't been planning on fingering her for any great length of time, she didn't give me the chance and looked back at me impatiently. "I said to put it in already, do you need written permission or something?" she asked. I shook my head and fished out my cock as she refocused on Zoey. I knew she'd only been teasing, but I was just irritated enough to do something about it. I'd never before in my life been anything but gentle when first penetrating a girl, but Mara was about to be the exception. As soon as I was lined up properly with her entrance, I shoved my cock inside almost all the way in one thrust. Mara's back arched instantly and she let out a long hiss, presumably in pleasure since she didn't say anything to the contrary. I pulled partway out, then slammed back in burying myself fully inside her eager pussy. She didn't seem to mind me being rough in the slightest, and I soon found myself getting into it more than I thought I would. It was kind of a nice change to not worry about my partner during sex and only concentrate on myself. Mara was getting off on the situation so much I could pretty much do what I wanted. For a while there was no talking at all, no communication of any kind unless you counted the incoherent sounds that managed to escape one of our mouths every now and then. I was so far beyond any higher thought that even the occasional moan that must have belonged to Zoey didn't faze me at all. I could guess what Mara must be doing to her, where her fingers must be, and if anything it only turned me on more. Any recognition that I shouldn't be enjoying the thought of my sister getting fingered by the girl I was fucking was fleeting at best, so fleeting as to be non-existent for any practical purpose. Eventually the pace I was maintaining caught up with me, as it eventually had to unless I gave in and slowed down. I could only fuck for so long before an orgasm started to creep up on me, and this one felt more intense than most. "Mara..." I gasped, surprised at my apparently sudden lack of breath, though I probably shouldn't have been. "Just do it when you're ready," she replied, able to correctly guess my intent. There was something in her voice that suggested she wasn't really paying attention to me, and to be fair she did have to concentrate on two things at once. I shoved my cock hard inside her, burying it in her one last time as I came. As some part of me had known would happen, I started feeling the inevitable guilt and regret almost before I was even done, while the last of my semen was still emptying into Mara's pussy. It had all made so much sense at the time, but afterward... I couldn't believe I'd really just done that. "Mmm, thanks baby," Mara said. "That was pretty awesome. Let me know if you want to do it again sometime." She winked at me again just before I managed to stumble to the door and out into the relative safety of the hallway. I'd only just barely gotten my cock back in my pants before exiting, but thankfully there was no one outside right away anyway. The last thing I wanted was anybody seeing me come out of that room and get even the faintest inkling of what I'd been up to. I didn't know how I was going to deal with it on my own, let alone if someone else caught on. **** Zoey didn't make contact with me for a couple weeks after the incident, as I'd taken to calling it when I thought about it at all. I didn't blame her, nor did I make any attempt to talk to her either. I didn't think it'd be like that forever, I really hoped it wouldn't, but I didn't think a little space between us was such a bad thing for a while. I think in the end I was more worried about Zoey's reaction to the whole event than she was of mine, which could have been why she came to see me before I built up the courage to go to her. It had been enough time that most of my guilt had dissipated anyway, and most of what remained was the fear of what my sister might still be feeling about it. I was just returning to my room one evening, not even thinking about Zoey or what happened, when I found her leaning against the wall next to my door, presumably having been waiting for me. "Hey," she said. "Hey," I said back. "What's up?" "We haven't talked since... you know." "Yeah I know. I'm sorry about... everything." I unlocked the door and let us both in to my room where there'd be less chance of anyone overhearing something. "It wasn't really your fault," Zoey said. "At least part of it was my fault." "Okay, but I'm as much to blame as you are. I could have stopped it. You even asked me to stop it. I'm the older one here it's supposed to be me who's responsible and stuff and... I just wasn't." We'd both had time to think, probably too much time to think really. Too much time to go over what we could have done differently. I could tell Zoey had been worrying about it just like I had and we both needed to know the other was okay. "Well, you might be older, but we're both old enough to do stupid shit," I said. "Can we just agree that that's what it was and move on?" Zoey cracked a faint smile. "Yeah, it was definitely stupid. I'm glad... I'm glad it didn't turn out worse." "Me too." We stood there awkwardly for a few seconds, then on some unknown signal stepped closer together and hugged. More than anything we said I think that helped get rid of the remaining tension between us. It reminded me that it didn't matter what we did, Zoey was always going to be sister and it would take something way, way more fucked up to ever make me wish otherwise. "So anyway, there was something else I wanted to tell you," Zoey said as we released each other. She sat down on my bed and waited for me to take a seat too. "What is it?" "Well..." she said, chewing on her lip thoughtfully, "maybe I shouldn't even say anything, and you can tell me if you don't want to talk about it, but you're really the only one who I think would even understand." "Go on," I prodded again. "Okay, so the thing is Mara asked if I would, like, ever do it again. Both of us I mean." "You mean that thing we both decided was a really stupid thing to do?" "Maybe not exactly the same, but... yeah, sex stuff. I told her no obviously." "Then what's the problem?" I asked, genuinely confused. "She's not pressuring you about it is she?" "No no, not really. Nothing I can't handle. But she asked what would make me say yes, and just to get her to shut up I said something like she'd have to let me fuck her in the ass with a giant strap-on." Zoey gave me a crooked smile. "I really thought she'd give up, but she thought about it a while, then said okay as long as it wasn't too big." "Oh. So now she thinks you're on board with her?" "No, I still said no." I sighed heavily, making sure my sister would catch the frustration I was starting to feel. "So what's the issue?" I said. "You're not making it very clear to me so far." "Because I actually thought about it," Zoey said, meeting my gaze directly. "I shouldn't have had to. I don't want to put you... either of us through that again. But I thought about it." "Why? You don't even like girls, you kept saying that when...." I stopped as a thought occurred to me. "Wait, do you think you might actually want to, I don't know, do stuff with Mara again? Is that what's bugging you?" "Well, it wasn't exactly unpleasant what she did to me I'll admit. She knows what she's doing. But I don't think I'm really interested in her if that's what you mean, I still just like guys. The thing is, there's some appeal in the idea of being on the not-painful end of anal. How many chances am I going to get at that?" "I hear it doesn't hurt once you get used to it anyway," I supplied, attempting to lighten the tone of the conversation a little. Zoey gave me a dirty look, as I'd expected she would. "What's bugging me is I think maybe I'm not as bothered by what happened between us I should be," she said, finally getting to the real problem. "Even while it was happening, I didn't tell you to leave when you asked me to and it should have been my natural reaction. And afterward... I spent a lot more time worried about you than about me because I just didn't feel some of the things I should have. I should have been a lot more weirded out than I was." I took a moment to consider what she said. In some ways I could see exactly what she meant. "Well, we couldn't really see each other or anything, and we didn't have any contact. Maybe that helped." "Maybe. Maybe I'm just a bad sister though." "Uh uh, no way I buy that," I said firmly. "We may not have ever been as close as some siblings are, but you're far from a bad sister. It could just be that we're more comfortable with each other than we thought, or something like that. That'd make you a pretty good sister, and even if that's not it I still think you are anyway." Zoey took my hand and squeezed it gently. "If you really mean that... then thanks. That's what I needed to hear. You're a pretty good brother too." **** It was a relief to have my relationship with Zoey return more or less to normal. It was one of those things where I never really realized how much I'd miss having her in my life until there was a real threat of something coming between us. Even if we went a while without talking or anything, I still knew she was there if I needed her and that was a very different situation than not being able to talk to her at all. When I got a text from her one day asking me to come see her at her room, I didn't think much of it and simply made the short walk there without bothering to reply. I didn't know why she would need me to come to her, but it wasn't like it was far enough that I'd mind even if it was something trivial. Since she'd only just sent me the message I assumed she'd be expecting me and I didn't bother knocking once I arrived. In hindsight, it might have been a better idea than simply opening the door as I did. "Hey Zoey," I said. "I got your text. Wha-" "Adam what the hell!" I stopped short halfway into the room as my sister hastily covered herself with her blanket. She'd been sitting on her bed with her laptop, and from the brief glimpse I'd gotten she didn't seem to be wearing pants. "Sorry, sorry, I didn't mean to...." I belatedly turned away from her while also closing the door behind me to keep anyone passing by from seeing inside. "You asked me to come though, I thought you'd, you know, expect me." "What? When did I do that?" "You texted me, like, maybe five minutes ago? Possibly less than that." "No I didn't, I--" Zoey cut herself off mid-sentence and I risked a peek to find out why. She looked as confused as I felt, but with an expression of dawning comprehension creeping over her. "Shit, she wouldn't have..." Zoey muttered. "Can you check the pockets of my jeans?" she asked me, pointing to a pair lying crumpled on the floor. The pair I assumed she'd been wearing until just recently. "Uh, sure." She was already busy checking the rest of the room from where she sat. Obviously she didn't want to move too much while still in her state of partial undress. "Anything?" she asked. "Just some change," I said. "Looks like mostly quarters." "Yeah I was doing laundry earlier. Shit. That means Mara must have taken my phone." "Why would she do that?" "I dunno, 'cause she's pissed at me I guess. I didn't think she was that upset when I said we weren't going to do, you know, that thing she wanted. She must have been though if she's trying to get back at me like this." "I guess. It seems weird though, I mean she of all people should know we've been through worse than me catching you...." "Masturbating?" Zoey finished for me with a slight smile at my embarrassment. "Yeah, that." "Well all I know is she's been obsessed with the two of us lately. She's kind of a weird girl." "I suppose we could take it as a compliment. You know, 'cause she can't stop thinking about us." "Yeah maybe. Except it's really only because of us being siblings and all. That's the main reason any of us keep thinking about it as far as I can tell. I know I spend more time thinking about... okay actually I just realized that's gonna sound really weird if I say it out loud. Nevermind." "You're really worried about something being too weird at this point?" I asked. "Because I think we're probably past that." "Okay, well... I probably thought about you more than Mara after we all had sex. And again, I know it sounds weirder than I mean it too." "No it's fine, I know what you mean. I was thinking about you a lot too." I sat down at the foot of Zoey's bed, careful not to get too close to her. "I was way more worried about what you were feeling than about Mara." "Exactly. Who cared what she thought, it was her fault to begin with." Zoey flipped her blanket off her lap and crawled over closer to me. She was wearing panties, though without looking directly I was mostly only picking up the fact that she didn't have any pants on with my peripheral vision. It was more distracting than I would have liked. "Are you going to put your pants back on or anything?" I asked. "Why, you uncomfortable with this?" "No, just... okay maybe a little." "Aw." Zoey put an arm around my shoulders. "I was going to tease you a bit, but you're making it too easy. They're just legs you know." "I know, but they're making me think about some other things." "So?" "So that's not good." "Oh whatever. It's not a big deal as long as you're just thinking. I thought we were past this awkward stuff." "That doesn't mean you need to try and make it more awkward." Zoey rolled her eyes and didn't make any move to put her pants on. It really wasn't a big deal if she didn't mind the possibility of my inappropriate thoughts, but at the same time I wasn't sure that was the sort of thing either of us should be encouraging. We'd been lucky not to have caused any significant damage to our relationship yet and it didn't seem like a great idea to tempt fate. "I'm not making it that awkward am I?" Zoey asked. "I mean, it's not like you're having to restrain yourself from molesting me or something, right?" She was right, it wasn't anything like that. At least, it wasn't until she gave me the idea. I knew she could win an argument with me pretty easily if I chose to pursue one, but now I had an alternate path to take. One that involved fewer words. As my sister sat there and waited for my response, I simply reached out and grabbed her boob. She looked surprised, not that I could blame her, but she didn't instantly push me away as I half-expected she might. "Adam... what the fuck are you doing?" she asked in voice that suggested she knew exactly what the fuck I was doing. "Molesting you, I think," I said. "Are you going to cut it out?" "Are you going to put your pants on?" We stared at each other some more, me keeping my hand on Zoey's breast and her not doing a thing about it. "I can outlast you, you know that right?" she said finally. "I know you don't really want to feel me up, you're just trying to make some kind of point." "If you say so." Of all the times I'd ever touched a girl's boob, or at least of the times it was on purpose, this was by far the least intimate it had ever been. Neither of us was even properly looking at the other, and our sitting position was such that I had to hold my arm at a weird angle just to maintain contact. There was a decent chance my shoulder would give in before either Zoey or I did. Since I was already in about as much trouble as I could get anyway, I decided to at least try and force some kind of action out of Zoey. I squeezed a little on her breast, not enough to hurt but enough to at least suggest that I was enjoying the situation. And, to some extent, I actually was kind of enjoying it. I hadn't realized at first over the knowledge that I was doing something really quite dumb and the slight fear that she might just punch me in the face, but her breast felt pretty good. In many ways it was not unlike any of the other boobs I'd fondled over the years, even if it did belong to my sister. Unintended Results "God, you're actually perving on me a little, aren't you?" Zoey said. I shrugged as noncommittally as I could. "It's not exactly unpleasant." "Yeah, I bet it isn't. You wanna know something though?" "What?" "Well, maybe it's just 'cause you interrupted me before I could finish getting off and I'm still horny, but it's not all that unpleasant for me either." "That kinda kills my bargaining position." "Mm-hm, I guess it kinda does. Are you saying you still think I should put some pants on?" "I might be wavering a little," I admitted. The corner of Zoey's mouth twitched upward in was not quite a smile. She moved from where she was sitting at last and I assumed she was going to give in, until she turned and sat herself down in my lap facing me. Her hands took mine and placed them on her butt before settling on my shoulders. "There's some upsides to my current outfit you know," she said softly. "If you thought about it hard enough you might find you agree with me." I didn't disagree, even without thinking about it for very long. What confused me was how my sister seemed to be doing something very similar to coming on to me. Granted I'd started it, but that hadn't initially been my intent. "You have a nice ass," I said, for lack of anything better to say. "Thanks." She leaned in closer to my ear and spoke barely louder than a whisper. "Whatever happens, we probably shouldn't say anything to Mara okay? At least not 'til we figure stuff out for ourselves. She'll just think she can push us into whatever she wants." "That's probably a good idea," I agreed. I had been getting hard already from touching Zoey, but that process accelerated greatly when she started grinding on my lap. She had to be able to feel my erection as it stiffened enough to make contact with her butt, and if anything it only seemed to encourage her. Moments later Zoey confirmed that she knew exactly what she was doing when she undid the front of my pants and reached in for my cock. She had to shift her body around in kind of a weird position to remain in my lap while doing so and I found myself having to lean back to give her more room. It just seemed easier to give up and lie back on the bed, so that's what I did. I figured Zoey pretty much had things under control anyway. "I don't think we should go too far," she said, taking advantage of the space I gave her to lean farther forward and brace herself with one of her arms. "But I'm gonna try and make this feel good for both of us. It's not really worth the possibility of disaster if we don't get anything out of it, right?" Her hand released my cock, and was replaced by her panties as she resumed grinding on my crotch. It was much more purposeful now, much more focused on results beyond just getting me aroused. As good as it felt, I could imagine her bare pussy feeling so much better sliding up and down my shaft, but without Zoey's panties between us there was too much risk of accidental penetration. It was probably for the best to avoid that possibility. In her position Zoey's boobs were almost directly above my face and I assumed, given the circumstances, that touching was okay at this point so I started pulling her shirt up to expose her stomach. She didn't say anything, but she did smile a little when I reached her bra, more than enough confirmation for me that I had her permission to continue. I couldn't get her shirt all the way off without basically pausing everything while Zoey lifted her arms, so instead I opted for rolling it up above her breasts where it seemed like it would stay put. Then I began working on unhooking her bra. "I hate to say it, but I think I am starting to sort of see Mara's point," Zoey said. "This is kinda hot in a fucked up sort of way." "Emphasis on fucked up. But yeah, I know what you mean. My brain's so confused about you being hot and on top of me, but also being my sister. It keeps telling me I'm doing something wrong, and somehow that feels good." "Mm-hm, weird isn't it?" Once I got Zoey's bra off I had easy access to her breasts and I cupped them in my palms, I was now able to feel them so much better than I could through her clothes. It was almost impossible to believe how many years I'd gone with no desire to ever see them now that I knew what I'd been missing, but of course things had been different then. It was just something I'd have to accept, that I might not ever be able to see my sister in quite the same way anymore. Whether it would make things better or worse overall, I didn't yet know. For several pleasure-filled minutes the entirety of my world was Zoey and her body and the way parts of it felt against mine. I could see her of course, and hear her breathing, but increasingly my senses were focused on my cock where the constant motion of her panties was working for me better than I would have expected it too. It wasn't as good as actual sex or anything, but it was definitely a step or two beyond masturbating. It seemed Zoey wasn't entirely in a agreement with me however. "This isn't quite doing it," she said, just a hint of frustration in her voice. "Okay, do you want to try something else?" "I think...." She looked at me, searching my eyes. "I think maybe if I put it inside. Just for a little bit, just long enough for me to get off." "I don't know, I'm kinda getting close and... you know." "I know, but you can just warn me when you need to pull out. Unless you're not ready for it, 'cause I know we said we weren't gonna go that far." She didn't stop moving as we talked, though she did slow down quite a bit until her hips were just rocking gently back and forth. I took a moment to think about my answer, but honestly I knew I'd go along with whatever she wanted. Partly because I was too horny to say no, and partly because, more than anyone else who could have been with me at that point, I trusted her. If she thought it would be okay, then so did I. "Okay, do it," I said. Zoey nodded and reached down to her panties, fumbling with them until they were out of the way and my cock was pressing directly against her pussy. She was more than wet enough for me by now, we'd been through the equivalent of some overly extensive foreplay after all, which was good because she wasn't in a particularly good position to guide me in and we had to rely somewhat on her body accepting me on its own. Once I was about halfway inside, my sister's pussy abruptly tightened on me and a look at the expression on her face suggested it was probably an involuntary reaction to what she was feeling. She appeared to be losing some of the control she'd had up until now and was giving in more to her instincts. There was a sort of an aura of primal lust to her, something I didn't think I'd ever seen before on anyone. I lay there and let Zoey fuck me, intending to let her go as long as possible even though, as I'd already told her, I didn't think I'd last all that long. Particularly with the way her pussy continued to grip me so tightly at semi-random intervals. There was only so much I could take. "Maybe we should stop soon," I said, hinting that I was getting close. Zoey seemed to ignore me at first, but after a moment she acknowledged my statement. "Not yet," she said. "I can't last that much longer," I warned her. "Just a little more." I tried my best to hold off my impending orgasm, but there really wasn't all that much I could do about it. I had no control over the stimulation I was getting short of pushing Zoey off of me, and force of will alone wasn't going to go nearly far enough. "Zoey!" She ignored me for real this time, and seconds later I came while still buried in my sister's pussy. I didn't feel bad about it right away, mostly I just got an extra rush from knowing I'd just done perhaps the most wrong thing of my entire life, and the fact that she didn't seem upset about it either helped calm any belated guilt before it had a chance to make itself known. I assumed Zoey must have cum right after I did judging by her reactions, though she didn't make it obvious. Mostly I was going on her lack of frustration as she lifted herself off me enough to let my softening cock out of her pussy. I doubted she'd look so happy if she still needed to get off. It was while we were just starting to recover and think about straightening ourselves up that I happened to notice something out of the corner of my eye. As I turned my head it quickly became clear what it was, or, more to the point, who it was. "Mara? How long have you been there?" I asked, too confused to muster more than a slightly puzzled query. Zoey looked too as I spoke and sighed heavily at discovering her roommate watching us. "Godammit," she muttered. "A couple minutes, maybe more," Mara said. "I didn't want to interrupt." "Of course, I'm sure it was purely for our benefit," Zoey replied sarcastically. "Just like that text you sent Adam." "Well it worked out didn't it?" Mara said. "You two went way farther than I even could have hoped. There must have been lots of buried tension between you." "So we're just as fucked up as you. Nothing to be proud of." "Maybe not, but does this mean there's a chance of another threeway happening?" Mara looked almost comically hopeful, like a kid on Christmas morning. My sister, however, was looking more thoughtful. "You know what, the chances get better if you give us a little privacy right now," Zoey said. "A lot better?" "Just go." Mara clearly didn't want to leave, but there was too much at stake for her to risk pissing off my sister and she knew it. A moment later I was once again alone with Zoey. "Can't believe neither of us noticed her sneaking in," she said. "Bet you she's right outside listening at the door." "Sorry, not taking that bet. I know her just well enough to believe she would," I said. "But, uh, I'm sorry about, you know, cumming inside you. I really didn't mean to." "Not your fault," Zoey said. "You warned me." "It's still kinda bad that it happened though." "Yeah, it kind of is," she said, laying a hand just above her pussy for a second. "But there's pills I can take, it's not a big deal. I don't even think it's the right time of month for me to have to worry about it, but no point taking the risk, right?" She stretched out on the bed beside me, then rolled on her side facing me. "I know we might decide later that this was really stupid, and it probably was, but I don't regret it right now." "Me either." I smiled and Zoey smiled back. "Were you serious about considering doing something with Mara again?" "I dunno, maybe. Partly it was just to get rid of her, but I guess we don't need to worry about it being awkward for us anymore. Of course now I'm not sure about it for different reasons." "Like what?" "Like I'm not sure if I want to see you with someone else now." "Zoey...." "I know, that's kind of dumb. But I'm just really confused right now." "Me too," I assured her. "We still need to work stuff out, we already knew that." "But I don't want to get jealous of you. I'm not your girlfriend or anything, I'm still just your sister." "My sister that I had sex with? What's that, like a sister with benefits?" Zoey giggled, and after a second so did I. "Something like that," she agreed. "But seriously, we need to decide what we're doing about Mara." "Do we really need to that urgently? She's not going anywhere." "Yeah, but think about it. She knows our secret and she could really help us keep it... or if we piss her off too bad by stalling...." "You don't think she'd actually tell anyone do you?' "Not really, but we already know she's willing to take matters into her own hands to get what she wants. Who knows what she'd do. All I'm saying is we need to be in control of the situation." "Well, to be honest, I don't exactly mind the idea of sex with her, but I don't want to do anything that's gonna bother you. So I guess it's your call." Zoey thought about it for a minute. "Yeah, I guess I probably am okay with it," she said. "She's only interested if we're both there anyway, so it's not like I'll ever have to be jealous of you two sneaking off without me or anything. Just promise we'll have some time just for us without her though, alright?" "Definitely. I assumed that went without saying." "Good." She raised her voice loud enough it could be heard out in the hallway as she called to Mara. "Okay, get back in here!" Not surprising either of us, Mara immediately opened the door and looked at us expectantly as she stepped back inside the room. "So are we gonna do it?" she asked. "Yes," Zoey said. "But not right now, so don't get too excited." "Aw, no fair. I got all turned on watching you and now I get left hanging?" Mara stuck her bottom lip out like a kid who didn't get their way, and even though I knew it was just to see if she could get to us, it actually kind of worked. She had a bizarrely sexy pout. "Maybe Adam'll fuck you if you ask nicely," Zoey said. "It's up to him, but I'm done for now. I got chafed a little too much on his pants, probably should have just taken them off in hindsight." Suddenly Mara's attention was all on me, and Zoey got up and moved to the other bed as though assuming my consent was a foregone conclusion. To be fair, it pretty much was. I would have turned down a chance at sex in a heartbeat if my sister was against it, but when she was the one suggesting it.... "Well... I guess if you watch it still kinda works," Mara said to Zoey. "How about it?" she said to me this time. "Not that I wouldn't do you anyway, but... you know how I am." "Yeah, I know." I honestly hadn't bothered taking any offense to the idea that Mara wanted my sister present, it was the kind of thing I expected from her. "If you want to wait for me to recover, I guess I'm up for it." "Oh I don't think it'll be that long," Mara said, a mischievous glint appearing in her eye. With no warning she pulled her shirt smoothly over her head, then crawled onto the bed with me. My cock was still soft, not to mention covered in a mixture of mine and Zoey's juices, but she didn't seem to mind and eagerly started working on getting me hard again. I exchanged glances with Zoey who offered me only a smile and a shrug, then I focused back on Mara who gave me a much more seductive smile. It was an odd sort of path that had taken me to a point where'd I'd get to fuck two girls in one evening, one of whom being my sister no less, but given the chance to do it all again, I doubted I'd change anything.
