I was 13 and discovered the public toilets down the road from my school were a beat. I'd go in my school uniform and stand at the urinal doing my best to look as innocent as possible and act like I had no idea what was going on. There would be 4 or 5 guys there, from late 20's up to early 50's, with their cocks out, big meaty mens cocks, or that's how they all looked to me. My heart would be beating so hard with a mixture of excitement and fear. It was a big turn on standing there with those men pulling their cocks and eyeing me off. It felt great! The first few times I went I would just jerk off and leave in a hurry as soon as I'd cum; feeling disgusted at what I'd done and swearing I'd never go back....lol (it was a catholic school I went to). But I couldn't help myself. After a couple of weeks I decided to go again and let a random man take me in his car back to his house and once inside he pulled down my pants, put me on his kitchen table, held me down with all his weight, stuck his raw cock inside me and fucked me really hard until he blew in my ass. He didn't say a word and I went home with his load still up my butt. and jerked off about 3 times that night thinking back over the whole thing.
