Raas Dein ~Captured in a Succubus Lair~

I’m a virgin captured in a succubus lair!
My days are filled with sex where even if I win or lose, I get raped!
9 succubus total, 8 of which will teach you a skill if they lose!
Human’s heads will explode if they try to escape the lair, so defeat Mao-kun to lift this curse!

Make sure to help him safely escape the lair!
