Seeking Looking for games where you fuck someone's partner while they thing you're their lover

An example of this was from a game who's name i don't remember, but in that game you're a friend of a couple and they're into "sleep" sex (i put quotation marks because in that game the wife is only pretending to sleep). Basically you know of their arrangement, and get to fuck your friends wife while she thinks you're her boyfriend roleplaying. Any recommendations welcome.
