As a young naive 18 year old guy trying to impress my girlfriend at the time, I took her out to what I thought was a very nice but expensive restaurant. Just as we were finishing our meals I went to find my small wallet and noticed it wasn't in the pocket I usually kept it. When my girlfriend asked for the bill and I saw the amount (It was expensive) I panicked. Telling her order a dessert, I walked up to the man who seated everyone and told him I'd lost my wallet. I tried to joke as he lead me through some doors and into a small office, saying I was very good at doing the dishes. He responded by telling me, he hoped I was very good at taking cock up my ass, as it was the only way I was going to get out without paying. He was much larger than me and looking at him properly for the first time, I saw just how intimidating he really was. Looking down at me he said "Well fucking undo your trousers boy, drop your underwear and then fucking bend over". Everything fizzed through my head and I was about to tell him where to go, until he opened his jacket. Even though I'd never had any form of male sex before, if I do say so myself, I took his cock really well. It hurt so bad at first, but by then I knew I had no choice. After a few minutes of him banging away at my asshole, my dick began to rise and before long I had the boner of all boners. As soon as he realised I had an hard on, he began to fuck me even harder and was cumming up my ass only seconds later. Turning me around, he dropped down, took my throbbing cock into his mouth and I'm not kidding, gave me the best damn blow job I'd ever had. When I came in his mouth he swallowed every drop. Walking out of the restaurant minutes later my girlfriend asked why I was so long and why the guy I'd spoken to had waved the cost of our meals. I lied and told her I knew him. Over the next few months I got to know him and his fat cock very well. I broke up with my girlfriend not because of the gay sex I was having, it was because she always wanted to spend all my money. I'm in a relationship now with a girl who knows about my bisexual life and enjoys the fact I'm open about my sexuality. She doesn't always want to spend my money either. The restaurant guy still see me every now and then, but I now pay for my meals and he offers me a wonderful dessert.
