I have a sister who's several years older than me. When I was younger, I shared a room with her. Sort of. There were these two bookcases between us, so technically it was like two rooms. Anyway, I was at that notorious age when I started to peep on her, through the space between the bookcases. I wasn't terribly discreet about it, however, and occasionally got caught. She would yell at me, but didn't do much beyond that. Finally, though, she got fed up,
and told our parents. What she said to was basically that I was just curious, and it would be for both our good if I was moved to another room, so they moved me to the old TV-room downstairs.

Well, there's one thing she was wrong about; it definitely wasn't curiosity. God only knows how she'd react if she knew just how not-curious I was. Just the knowledge that I always got a hard-on looking at her I think would freak her out. And that wasn't the half of it.

I remember the incident that started it. I was hanging out in my sister's half of the room for some reason, I guess I was looking at one of her D&D books, and I guess she needed to get changed for something, because she told me I needed to get out, I said just a second, she said seriously you need to go, and I said hang on, so she got fed up, and took her top off right in front of me, at which point I took the hint and went to my half of the room. I think the reason she wasn't shy about just flashing me like that was she figured I was still in my "Girls are gross" phase. Boy, was she wrong, because afterward, I couldn't get that sight out of my head. To give you some idea, my sister, like all women in my family, is "big" or "thick", whatever word you wanna use. She has large, natural breasts, like F-cup range, but that wasn't what stuck them in my mind. The thing I really was fixated on was her large, brown nipples and aureola. We're white, by the way, so that definitely stands out.

So when I first started peeping on her, I would just watch her and get a hard-on. After a while, though, my imagination started to get in on it. As I watched my sister strut around topless, breasts swaying as she moved, I started to fantasize about grabbing and squeezing her big tits, and licking and sucking on her nipples, and her sighing and moaning with pleasure. Yeah, even then, I was a little more sophisticated than other kids my age. I also had seen my first porno about this time, which didn't help things. Occasionally, I would even get a shot of some bush; my sister kept hers natural, which, like the brown nipples, gave me a fetish for this kind of thing.

The ultimate, though, was, one time, she was sitting on her bed, in I guess what she thought was a blind spot. She had her panties off, and, when she sat down, she spread her legs. I couldn't believe my eyes; I was given a perfect view of my sister's pussy! I then figured out what she was doing; she had these pads, like acne pads, or moist towelettes, but something else I guess related to feminine hygiene, and she started to wipe down her twat with them, including holding it open to get inside. At first, I was too shocked to react, but, after a moment or so, my brain clicked back on, and I started to imagine the pad she was using was my tongue, and she was once again moaning gratefully, even whispering "God, ____, that feels soooo good..." The funny thing is, while I was watching and thinking, I guess she figured out I was once again looking at her, and yelled, "____, quit staring at my tits!" Yeah, she had no fucking idea.

It wasn't too long after that she went to our parents, and, again, it most definitely was for my own good, as God only knows what line I would've crossed if she hadn't kicked me out. Now, we're both adults, and there's absolutely no awkwardness; she's just my sister, and the very idea of thinking about her in that way repulses me. But, every now and then, I wake up from a dream, involving her, the way I remember back then, with a raging hard-on, and some of the more lurid details of the dream fresh in my mind.

God, I hope she doesn't read this.
