Three years ago my Uncle Kyle moved in with us for a short time after his marriage broke up. I'd only just had my seventeenth birthday and didn't really wan t him moving in with us. It was for selfish reasons and reasons I didn't want anyone finding out about. Not long before before he moved in, my girlfriend at the time had been penetrating my ass with her index finger when we were fucking. I'd come to like it and had experimented at home inserting various things up my butt to help me attain a better longer lasting orgasm as I masturbated. Only a fortnight before he moved in I bought my girlfriend a dildo to use on herself when I wasn't there, at the same time I bought myself one and that was the reason I didn't want him moving in, as he was going to cut into my anal experimenting.
I'd been out with some friends on a Saturday morning but had only one thing on my mind and that was getting home to fuck myself, thinking my parents and my uncle would be out. My parents were out shopping, but when I got in I could tell my Kyle was upstairs as I could hear him moving about. Pissed off I climbed the stairs to have a shower and noticed the guest room door open. Looking inside I saw Kyle lay on his back on the bed. I also saw him wanking what I now know to be a cock which measures (I've measured it) just under nine inches. The thing that really caught my attention other than his massive cock, was what he doing with his other hand, he was holding up what I suspected to be a pair on my moms panties to his face and he was sniffing them. I didn't burst in and ask what he was doing, I stood and watched him wank. After a minute or two I began to wonder what it would be like to have his cock pounding my ass instead of the dildo I'd bought. Stepping inside in an involuntary action he immediately saw me, quickly he was trying to hide the panties and his cock at the same time. This is where I became a devious bastard, looking at Kyle I told him I'd seen him sniffing my moms panties and maybe I should tell my dad, unless. I left the word hanging until Kyle said "Unless what".
Kyles dick was still hard and with some more blackmail, a lot of patience and some hand cream I'd gone and got from the bathroom, Kyles cock entered my asshole. It wasn't the same as when I fucked myself with the dildo, it was much more painful, but at the same time, it was to me at least, much much more horny. After the initial pain went, it was replaced by a throbbing feeling that grew deeper and deeper inside my ass. Kyle had forgotten he was fucking his nephews ass by this time and had begun to thrust into me and I'd begun to enjoy the growing feeling of pleasure inside myself. When Kyle made me kneel up and pushed his cock back into me from behind I really began to enjoy and want him fucking my ass, pushing back onto him.
It was an amzing sensation when I came, I wasn't touching myself, I was too busy holding the pillow and my right butt cheek. The orgasm seemed to start in my head, then quickly flow through my ass, cock and body. I was shaking with total joy and asked Kyle to fuck me harder. Within a minute of him pounding into me again I felt him collapse on top of me as his cum shot up inside my bowels.
We lay there for a minute until Kyle lifted himself off me. Turning me around he told me, not asking, told me I was going to let him fuck me when he wanted. I just nodded, still reeling from my prostate orgasm.
Kyle and I fucked when we got the chance for next four months until my mom got sick of him being around and made him find somewhere to live. Luckily for me it was only two blocks from our house and every opotunity I got for the next year, I would visit him and we'd learn from each other what we enjoyed sexually together. I finished with girlfriend when I began to enjoy being fucked, more than I enjoyed fucking her.
Kyle moved away not long after that and I soon began to notice guys which I knew were at least bisexual, if not gay. I suppose the saying is right "You have to be one, to know one".
Kyles cock is still the longest cock I've had fuck me, it's not the thickest though. That particular pleasure is the person who I occasionally have sex with, it's a guy who's also married and lives a cross the street. Helping him with a gardening project last summer, gave us both time to get to know one another in his tool shed.
