CEMD-030 Invitation to the pleasure and debauchery hell for M3 sisters! It's easy to enter, but once you're in, you can't escape the pleasure trap!

Upon learning of the existence of a matching app that finds S-type men to their liking, the masochistic slutty girls head to the men they've been matched with and receive torture beyond their expectations from men honed in S, reaching climax. Eventually, the three sisters end up facing an S-man who transcends dimensions, dragging all three into an M-pleasure hell. They drench each other in fluids, with the sister choking the younger one and the younger one pinching the sister's nipples! The masochistic trio, marked by their extreme M tendencies, stumble upon a horrifying app that sets off a gruesome scene!
