My older sister Nadia and I had always been close, but it wasn't until she graduated high school that we really bonded. She decided, with my parents' blessing, to take a year off to just relax before heading off to college, and so she was around with nothing to do for pretty much my entire school year.
Not that I minded, really, because, like I said, we bonded. Every day, after I came home from school, she would ask me about my day. I'd tell her about whatever was troubling me, like grades or teachers or just people I plain didn't like, and she would listen to it all and give me advice that could only come from someone who had to deal with it all before. I really liked that she listened, and started to depend on her to help me get through my final year of school.
Of course, it certainly helped that she was easy on the eyes, something I didn't notice until we started hanging out a lot more. At first it was little, harmless things, like noticing how her long dark hair hung over her eyes when she tilted her head a certain way, or the graceful way she moved, but as I grew more and more into my role as a sexually frustrated teenager, I noticed more. I would find myself glancing at her big tits as she talked, or watching the way her nice ass moved when he would walk by me. I'll admit it; it's hard being a sexually-frustrated eighteen year old boy when you have a hot sister living with you. Whenever I would jerk off, I would find Nadia intruding upon my fantasies. Again and again I would imagine her stripping in front of me, or what those gorgeous tits looked like when they were freed from her bra. It got to the point where I wouldn't even fight it anymore and masturbate to the thought of fucking my older sister. I would feel guilty, yeah, but it wouldn't stop me from doing it again.
Of course, a lot of it came from the fact that, as I said, I was getting cockblocked on a regular basis. Whenever I could actually get a girl I was interested in alone with me, we would fool around for a while until she'd stop me, panting and nervous, and tell me we were moving too fast. That was kind of the problem as I saw it; time was moving too fast. In a year I would be off to college, and the thought that I would graduate a virgin was preying on my mind.
All of this I kept as best I could from anyone, but I think my sister intuited my problem, at least a little, considering what happened. Either that or she'd been checking me out as much as I'd been dreaming about her.
The day it happened, I was late coming home. I'd stayed a couple hours trying to work through the pile of homework that would carry over into my weekend, and failed miserably. Added to that the fact that, the night before, I'd gone out with Stacy, who'd let me go so far as to finger her before telling me that she wanted to save herself for marriage. It had gotten to the point where I wondered what I was doing wrong.
Such was my mindset when I crossed my front lawn, backpack over one shoulder, to see my parents' car missing from the driveway. Dimly I remembered them saying they would be out of town for the week and warning me against any parties, but I hadn't really been paying much attention. It didn't really matter, however; I had enough of a work ethic to know when to party during the weekend and when to buckle down, and this was definitely time for the latter.
I walked into my house, throwing my backpack in a corner where I promised I wouldn't look at it for a whole hour, then started up the stairs to the bedrooms.
"Nadia?" I called out. "You home?"
"Up here!" She answered back, and I followed her voice into her own bedroom, where I found her sprawled on her bed, flipping through a magazine.
I tried not to stare at her too much, but it was hard. Her blouse was tight, her tits straining against the fabric, and I could make out the outlines of her bra. In my mind's eye I mentally placed where her nipples would be, and felt my cock stir at the image. He jeans were tight, too, accenting her wide hips, and I followed her legs with my eyes to her feet, which were crossed carelessly at the end of the bed.
I tried to contain the fantasies, like I always did around her. Sometimes I even succeeded.
"Hey, Jake!" She said, sitting up and throwing the magazine on the floor. "What's up?"
"Nothing much." I admitted. "Shitty day."
"Well, sit down here and tell me about it." She patted a place beside her, and I fell onto the mattress gratefully, trying to keep the bulge in my pants showing to much.
I told her what was bothering me, about my grades being behind and the homework I would have to do. She told me to relax.
"You got all weekend." She said, smiling. "Why not wait until Sunday? You could spend Saturday just hanging out, maybe take a girl to dinner or something..."
"Oh, God, that's another thing." I said, not really thinking about it but needing to vent. "I keep striking out with girls. I don't know what's wrong with me, but..."
"Wait, wait..." She stopped me. "Hold on a second. What do you mean you keep striking out? Didn't you just take that one girl, Stacy, out last night?"
"Um...yeah." I admitted lamely. "Yeah, I did, but..."
"But what?" Nadia asked. "That doesn't seem like striking out to me."
I shrugged, not having any idea about what to say. I couldn't see myself admitting to my older sister that I was annoyed my date didn't put out. Not only because it sounded shallow, but because she was my sister, and I was still a little weirded out that I couldn't be in the same room with her without thinking about what it would feel like fucking her.
"So, what's the problem?" She pressed. "Was it just a crappy date?"
"No, no, it was fine." I admitted. "Just fine. I, um...just after..."
"What do you mean, just after?" She asked. "What'd you guys do, anyway?"
"Well...we went out, watched a movie..." I cleared my throat. "Made out a little bit..."
"Oh yeah?" Nadia raised an eyebrow and I felt myself flush.
"Well, it's not what we did, it's what we didn't do." I said, finally getting it out. I got the reaction I'd expected. Nadia broke into a huge grin and started giggling.
"Oh, my God!" She exclaimed. "You mean..."
"Yeah."
"You didn't...you didn't go all the way?"
"Yeah, yeah." I rolled my eyes. "Yeah, that's it."
"Oh, wow, Jake." Nadia stifled another giggle. "I mean, I'm sorry and all."
"Look, it's not a big deal." I flustered. "Let's just..."
"No, no, it is a big deal, really." Nadia breathed deep, and I was uncomfortably aware of the way her chest came out when she did it. She was obviously trying to get her laughter under control, and as I waited through it I found my eye wandering down to her breasts. I snapped them up guiltily, forcing myself to stop it.
It was going to be hard if I didn't get laid soon, I remember thinking. My sister was just too hot not to fantasize about.
"Okay, okay, I'm better now." She said. "So...when was the last time you did it, then?"
I shrugged. I really did not want to have this conversation with Nadia, especially not since I was a virgin, and ESPECIALLY not that I kept thinking about her nude.
"Well..." I stalled.
