When I was seventeen, I stupidly walked into a guys open garage and tried to steal his bike. Before I got ten feet I was grabbed, punched and then pulled by two men into the kitchen of the house. Forcing me down, I was pinned. The two men discussed whether to call the police, but decided on something else. Within seconds I had practically every shred of clothing ripped off me and was stood in just my sneakers and socks.
Pushed violently over a breakfast bar, I was held tight by the larger of the two men, whilst the other guy got up behind me, spread what I later found out was margarine all over my asshole and then his cock entered me. I tried to shout out as it hurt like holy hell, but the pain was too much and I then had a hand cover my mouth.
I was fucked in that position unable to move for about five minutes and in that time the pain went. It was replaced by a very real growing feeling of utter anal ecstasy. My moans changed from ones of pain to ones of pleasure and they both noticed. The guy holding me began to call me a cock slut, then told his friend to cum quick as he wanted his turn.
A few seconds later my asshole was filled by the first mans hot cum. Then as quick as a flash, I was re entered by the second older bigger man. And not only bigger in height either. His cock was much thicker than his mates, yet my asshole surprisingly accommodated it relatively easily. He fucked me like I was just a hole to bury his cock up, and to him I suppose I was. With each thrust of his cock deep inside my ass, the feeling of pleasure grew in me and without wanting it to, or meaning for it to happen, My cock erupted and I came all over the floor below me. the man fucking me saw and heard me cum, making him fuck me even harder. I was being fucked so hard, I was literally bouncing off the breakfast bar. He made a series of loud groans and then shuddered inside of my body as he too unloaded up my ass.
Pulling out, he kept a firm grip of me, spun me around and told me to clean them both off. For the next five minutes or so, I was forced to lick and suck their cocks clean.
Telling his friend to get me something to wear, I was given a pair of shorts and a t-shirt. Then told in no uncertain way, if I told anyone about them fucking me, they'd make sure they put it out there, I wanted it. Then just before I was shown the door, the older guy told me "Anytime you want to call by and get fucked again, feel free to do so". They both laughed, but they weren't laughing when I called by a few days later.
For two and a half years I has sex with both men. Not always together, as the younger of the two worked away a lot. But when we were all together, we had some extremely wild times.
Girls, the discovery of pussy, life and eventually marriage ended my gay experiences (So far). But I've never forgotten how I was initiated into having my asshole fucked, by two very active large cocked bears.
