As far back as I can remember, I've always known my sister was a bona fide hottie. She was when we were 12 and we moved; she was when I was cresting puberty and discovering just exactly how awkward boners can get; she was when she finally left me in peace and went to college. I knew because I couldn't not know: literally all of my friends growing up had huge crushes on her and weren't even remotely shy about letting me know it. Throw in an unashamed slutty streak she went through in high school, and it was pretty much impossible for me not to admit that she was a solid 9 or 10 across the spectrum of male desire. All that said, I was really very good about compartmentalizing my heterosexual male desire for women with the fact that she is my sister.
At least until I saw her naked, which was what started the whole fucking mess.
It happened by accident one day after she'd come home from college for the summer. Mom and Dad brought us out to the lake the first Saturday she was back. She'd spent the last few summers working near her college as a waitress, so I hadn't really seen her in quite a while. Our parents were excited to have the whole family back together, and decided to make the day trip as a sort of celebration. We lived in a pretty small town then so beach trips were big news, and since we were so close with all of our neighbors most of them came along. My dad brought some of his single friends, my best friend Joel and his family came along, and our next-door neighbors came along with their only daughter, Lauren.
The neighborhood was so small that it was pretty much a family affair, and it was a pretty PG-13 affair for the most part. Lauren and I were dating on and off on the sly then, and had been for the last six or so years. We were only 18, and we didn't want our parents or anybody knowing anything, so we were pretty quiet about the whole affair. And to be honest since she was pretty religious we hadn't really done much together physically, but we'd been very close friends for the ten years since I'd moved in next door to her. I tried some moves, but under her parents' strict watch I knew nothing was really going to happen anyways. So after I got denied once more trying to cozy up to her while the sun was setting, I gave up and fucked off to the lake's changing stalls.
It was, I maintain, merely a happy accident that when I pulled a privacy curtain roughly aside, Brittany happened to be behind it. She was toweling her blonde hair, both hands above her head, her delicious-looking breasts riding high on her chest, pert and perky. Brittany had huge breasts, or at least large ones. I pegged them at either Ds or DDs. They sat naturally on her frame; she was almost as tall as I was, and I was an athletic 6'1" at the time. My eyes wandered lecherously down her body in that moment, all too brief, past her taut fit tummy down to her stubbornly shaved snatch. I don't know for certain whether it was shaved or waxed, but I can state with authority that I never even once saw even a glimpse of stubble anywhere near it. Her thighs were muscular but not especially lean, suggesting an incredible ass that at least then I didn't get a look at. The whole moment lasted less than a second, but is imprinted on my mind forever.
"Eek!" she shrieked, proverbially slamming the curtain shut. "Jesus Christ!"
Indeed.
I was frozen there, a second or two, before I ran away. Ladies and gentlemen, I literally ran away, as though I was frightened. Maybe I ran from my thoughts. Maybe they were chasing me.
Outside the changing stalls, my Mom asked me if I had seen Brittany.
"No," I insisted, "She's my sister! I'm riding home with Joel."
Of all my friends who ever crushed on Brittany, Joel crushed the hardest. He crushed to the point where it was legitimately creepy, and sometimes I had to wonder whether he was really my best friend or if he was just hanging around me for opportunities to hang out near Brittany, but when she went away to college and he stayed, I figured he was legitimately a bro. So of course I had to talk to him.
"I can't believe you saw Brittany naked," he whispered back to me in the back seat of his Dad's van, "What did she look like?"
"I don't know," I said, "I don't want to think about it." The truth was, I couldn't stop thinking about it. Just to keep myself from whipping my dick out and masturbating right there, I was running my anti-boner thought reel through my head on repeat. (For those curious, imagine Winston Churchill fucking Margaret Thatcher and may you never be hard again.) Joel, however, was not to be denied.
"What do her boobs look like?" he asked.
"Like tits," I said, "Just, whatever."
"What color are her nipples?"
"Pink," I said without thinking.
"Oh god," he said, "How big are they? Are they pointy?"
"They're a little pointy, I guess."
"How big around?" he asked.
"The areolas? I don't know. Medium, I guess?"
"Oh man," he said, "I'm going to imagine her with tiny ones."
You can probably guess that Joel didn't have all that much experience with women at that point. It blew my mind back then. The guy grew up inexplicably dark-skinned and lean, but a little on the lanky side. He was an attractive guy by all means, but he just didn't get blessed with the social graces. Not that I had all that much experience to brag about, but in one of my off phases with Lauren, a girl named Marie took my virginity on my couch. Compared to Joel, I considered myself a veritable ladies' man.
Not that I was immune to Brittany's beauty. Once I was safely home in my room and behind closed doors, I was ready to clear out all sorts of uncomfortable sexual energy. I stripped down to my boxers and my erection was just about ready to force itself free. I shut off my room lights to hopefully discourage any unwanted family entry. Only the light from my computer screensaver lit my room, since this was back when those were popular. I quietly started rubbing myself seated on my computer chair, when I caught sight out my window of the light from Lauren's room next door.
Yes, my teenage girlfriend was literally my girl next door. And she looked every bit the part as well. Lauren appeared in the little frame of her window, all tiny little 5'2" of her. She had long dark brown hair, and she was wearing her bathrobe. She walked up to her window frame, and caught my eye. I knew what was afoot.
