Does anyone know the name of the H-Game that was pretty much the ero version of Zero Time Dilemma?

You wake up in a room with 5 girls and you have to do progressively more sexual deviant things each round to survive the game. Its like a mix of saw, hentai and battle royale.

It was a pretty standard visual novel. Drawn anime graphics. I cant find any screenshots because I can't remember the name of the game.

I think it was just one word... the main female character was blonde who wore her hair in a bun. As you progressed through the story, she wanted you to keep picking her for the sexual games. I can't fucking remember though!
