I sometimes find it difficult to keep track of stories I like, and which manga/doujin they appear in. And I swear I saw a story like this, but I can't remember where it was, though I'm fairly certain I had it, at least at one point. (On my computer, at least.)

I'm hoping the good people here can tell me which book it appeared in. I can only describe parts of it, so I'm hoping that it will be enough.

Basically, the story takes place in what I think was a diner or restaurant of some kind. A woman, a girl, and a boy are there. They are in bondage-style gear. The boy has a thing over his penis. The girl sits in a guy's lap, and gets it up the butt. The woman takes the thing off of the boy's penis, and the boy does the girl in her vagina. Then the woman takes the thing that the boy was wearing, fastens it to her outfit as a strap-on, and does the boy up the butt.

I tried to keep the description clean

I don't know if it was in an anthology somewhere, or a specific artist's book. But I'm sure I have the description right. Does anyone know where it is from? If so, and I still have it somewhere, I'll be more than willing to zip the contents and share
