No, I have never played with a total stranger, only with my partners/friends or at least good acquaintances.

But being used by stranges works with one of my fantasies, which I might even try to realize some day:

The condition is, that there is one person of trust who organises everything and picks the strangers and makes sure they are all healthy. Ideally the person would be friends with those people who are strangers to me. Their gender doesn't matter to me.

The fantasy is about me getting abducted and brought into an abandoned place. I'm tied up, maybe blindfolded and totally vulnerable. Any number of strangers use and abuse me as they please.
