The clients can't see my face and I can't see theirs

I imagine a fantasy world with stores where you can buy a sexual experience. And I'm one of the women available in the store. I'm safe within a sort of membrane: it is dark and elastic, with 4 holes in it, one for the mouth, one for each breast, and one for my pussy. The clients can't see my face and I can't see theirs. Here, anonymous people can come and do whatever they want to me.

I dream of a mysterious man, with a 3-day-beard, older than me. He would take his clothes off rapidly, and begin touching my breasts immediately. I can't resist him and I like the way he touches me. Then he would put his fingers in my mouth and into my pussy, and finally fuck me like it was his last day on earch. I can't escape the ecstasy - the membrane holds me. He can take me and do whatever he wants.
