SUPRISE SUPRISE

A few weeks ago, after a party I found myself face to face with a stranger's cock. I was stunned, shocked but strangely curious at that dick. He slapped me around the face with it and tapped it on my nose splattering pre cum on me. I guess because I wasn't protesting, he assumed I was gay. He knelt between my legs, gabbed both our cocks and jerked them (I believe they call it frottage). I looked as he did so then at his face then back to the cocks. I couldn't believe what was happening, the pace quickening, our glands on view then gone on view then gone as the foreskins danced together. I knew he was going to make me cum and sure enough I oozed cum from my shaft onto the head of his cock. I couldn't believe what I'd done, I looked at him, he just smiled and tried something else. I don't know what you call it but he pulled my foreskin over the head of his cock and wanked until he filled my shaft with his seed then gave me head. Well at the first opportunity I was out of there. He keeps bumping into me though and wants seconds, don't know what to do?
