When my hot older sister and I lived in the same house, she was my daily sexual obsession. That's the correct term. I was obsessed with her 24-7. Her amazing body, 38C tits, perfect (by her own admission) ass, pretty face, long auburn hair, and, our shared thing/fetish..Killer long, polished nails. She loved the attention I gave her nails and her, and I loved giving it to her. She'd flirt, wear very skin-baring clothing, and we'd go tan at the state park, where she'd wear her tiny, black bikini and joke with me about my "reaction" to her in it. As in, hard as a rock. We had a good thing going, but I knew it could be better.

I began going into her bedroom at night and feeling her up. First, just a few times, maybe go inside her robe to cup those bulging tits, but soon...I was going for her crotch and mound, with excellent success. I'd often thought she knew, at least sometimes, that I was doing it, pretty much every night, but keeping quiet about it. Then one day, taking me to a part time job I had, she said to me in her car "If you come in tonight, there might be a surprise for you..Yes, hun, I know you come into my bedroom, so let's not even say you don't.. I don't mind". Sure, I was surprised, but also way curious..What surprise, and was this a trap?

I worked, she picked me up, and offered nothing about the supposed surprise. We went through our respective evenings, and she went to bed (which I had down to a science). I did notice she'd re-polished her nails a hot, fire-engine red, which drove me hard and crazy, but other than that, wore her usual short, white robe (which I'd cut higher so she'd show more legs and ass..she wore it anyway). Later that night, I got up, maybe 3am or so, for my nightly bedroom visit and body enjoyment of her. When I reached under her covers, I felt bare skin and she was facing me, providing a direct feel of her mound. No sooner did I start to play with and lightly finger her, did I feel her long-nailed fingers on mine.

"Get in, and show me what you got, hun..If you're hard for me, show me..Then get on top of me" she softly spoke. I was hard as hell for her, as she was asking me to show off my cock, and fuck her. Pulling my shorts down and letting my rather large cock into the air, my sexy sister reached for it, wrapping those nails around it, and telling me "Knew I did this to you..Now, do as I say and get on top of me. It's time you get what you want from me".

Crawling into bed with my naked older sister, I had at her hard, fucking her so hard and fast the bed was starting to hit the near wall. Her shrieks and moans into the pillow told me I was doing well, as did the sinking nails into my arms and back. We fell asleep for about two hours, then she nudged me, kissing me twice, telling me you better get up and go to your own bed, and that "we'd do more later today" because "when I take you to work, you're not going to work". We ended up at a motel about 5 miles from home, letting loose every sexual desire and need we'd had for each other. To our credit (mostly hers..I'd have told everyone I knew), we kept everything strictly between us, and continued for years. I even fucked her first after her first marriage, at the reception.
