Though she was a beaut in her teens, it wasn't until she hit eighteen that my sister Nora had blossomed into her fullest sexual potential. She had always caught my eye, but she was positively enrapturing that year. Long curly black hair fell across her pale-white shoulders, her scrumptious breasts sat perky and full, and, well, my object of true desire had gotten more exposure that year than any other: her large, soft ass. Bouncing in a deliciously tight one-piece bathing suit, it made that summer more agonizing than any lust-spree I had encountered with her previously. It was particularly noticeable in the black-and-white striped suite, which accentuated both her breasts and ass, notifying me of every bump and grind encountered in our backyard swimming pool. So, yes, my little sister might be the thing I've masturbated most about in this world, and it might have a lot to do with her ass. The problem? No, sorryβthe solution? She knew it.
See, Nora was a special girl. Both endowed and aware, she was one of the most sexual people I knew on the planet. None of my pervy friends could compare to the secrets she'd share with me. Inept with technology, she depended on my pervy-techno sensibilities to find her the best hentai videos. I'd then slip by her room and take my repayment in the form of overhearing her wet pussy slop against her hand over and over again. Both a chronic masturbator and lover of all things sexually deviant, Nora devoured my subtle attraction like watermelon in the desert. I didn't find out about this until
after
, but needless to say she was devilishly good at hiding it.
It started with the teasing. Her 18
th
Birthday party had been an absurd affair. Our parents left for a private weekend to let Nora spend some time with her friends, but that resulted in a drunken gathering of all of my sister's closest friends. They watched obnoxious videos on YouTube and drank wine like water, but they were all reasonable people and I was more than happy to help prepare and entertain my sister with the rest of her friends. She uncharacteristically wore a low-cut top and form-fitting shorts, which made the entire night extremely uncomfortable for my constrained genitals. She would later tell me that she stole glances in the moments where I couldn't hide it. It's a turn-on now, but it was hellish at the time.
The worst, and simultaneously the best, was the spring before the revolutionary summer. It was both the tipping point and sheer embarrassment wrapped in one gigantic masturbatory moment. Nora and I may be strangely close in terms of sharing sexual preferences and tastes, but we rarely discussed
our own
sexual functions. I knew what pursuing hentai and other dirty websites meant, but rarely did we discuss it. It was a strange line to walk, but we walked it and I enjoyed looking at her ass sway down the fine line. Her walking into me masturbating, right after I had glimpsed her walking into her room after her shower? That was different.
