It happened a few years ago. I was on my own, and I was sitting right next to this old gentleman, who just couldn't keep his eyes off me. To be fair, I was wearing some very revealing clothing, so I can't judge him. Suddenly, midway through the movie, it just hit me: Why don't I just give this guy, what he wants? It would be so hot. And so I asked him. He was a bit hesitant at first, but he warmed up to the idea.
I unzipped his pants and went down on him. He started breathing heavily and was desperately trying to muffle his moans. It didn't take too long, before he came all inside my mouth. After the deed was done, he thanked me and I left the cinema. I didn't even finish watching the movie, lol.
This is definitely one of the slutiest things, I've ever done.
