amok: Succubus (
https://www.gog.com/game/succubus) have graphic sex scenes and (a lot) of nudity.
morolf: Is it meant to be sexy though? I thought it was a game set in hell, with a lot of graphic violence.
Also, the very thought of a succubus demon who rips off men's genitalia is pretty unerotic imo. I certainly wouldn't want to meet such a demon.
just because it is not your kink, does not mean others don't find it sexy. it links into the whole S&M / BDSM culture. It is described as an 'erotic' game. There are other games likewise sold on horror, sex and violence, for example
Lust from Beyond edit - might also just point out that ripping of men's genetelia is just one thing the protagonist does. She also do many other 'things' to both human souls and other demons during the game.
