The Adventures of a Masochistic Hero

Peace didn't last. A new race of succubi has taken over, turning women into more succubi through "Succubus Corruption" while men get drained to death by their sexual torment, and the grown-up hero who once beat the Demon King is the only one left standing in the way.

The setup sounds grim, but the game says outright that the plot is secondary. This is an RPG built around watching that hero get overpowered and drained by one succubus after another, humanity-on-the-brink stakes included.

Combat runs on turn based RPG mechanics, with the hero facing down a rotating cast of monster girls and futa/trans succubi who specialize in draining him through oral, footjob, and titfuck attacks rather than blades. Female domination is the constant; the hero's masochistic streak is the point, not a side effect. Multiple endings are on offer depending on how badly, or how thoroughly, he loses.
