Seriously, can someone please explain to me how I was supposed to just not notice that my older sister was mind-meltingly hot? She is 3 years older than me. I started "noticing" her when I was about 13 or so, and she was 16. There was simply no way to avoid it, her body was simply stunning to me and I lusted after her constantly. I'm pretty sure she kinda knew it, too, but never really said anything about it.
I can't ever recall a time when I didn't have a raging erection when I was around her. I lived for moments I got to see her in a bathing suit, in a pair of tight jeans, or in her underwear, and tried desperately to contrive ways to get a glimpse of her nude. There were a few such moments... A couple times I saw her without a top on, sunbathing in the back yard, and on odd occasions I caught fleeting glances of her nude in her room or in the bathroom. Those images are pretty-much burned into my brain, and I had them constantly in mind when I masturbated.
I relished any opportunity to spend time with her, particularly if there was a reason for there to be physical contact. When we would hug--I can't lie--my hormones just raged at the way her body felt pressed against me.
I knew how "not normal" my attraction was, but still couldn't help the urges I had--I desperately wanted her to know that she turned me on. I badly wanted her to see me with an erection, and possibly catch me masturbating. That never happened, but--again--I suspect that she knew what was on my mind. I remember one night being so worked-up, as I lay in bed, that I had concocted a fantasy about walking into her bedroom, confessing everything, and actually begging her to take off her clothes with me. I'd "reasoned" it all out--that it would just be a silly thing where she'd think it was "cute" and would indulge me out of pity or affection, or something. I'm really glad I never actually did anything so stupid...
She had boyfriends all through high school, and was sexually active--I think--by the time she was about 15 or 16, and I remember how jealous it made me feel. It wasn't until quite some time after she'd moved out and gone to college that I was able to put my lust for her to rest.
To this day I can't help but see a gorgeous, sexy woman when I look at her, and I have to fight the urge to be turned-on. If a real opportunity to have sex with her presented itself, I'm 100% certain I would take it.
There. I said it. I wanna nail my sister. Jesus.
