アイアンメイデン

The result of another of Lily’s experiments in transforming a villager into a torture device, it locks a man inside its body and uses every aspect of her interior to stimulate the man. Filled with tentacles inside of her body as he’s left unable to move. Once locked inside, the amount of force needed to open her back up is greater than the power of twenty men. If caught inside, there is no escape. The Iron Maiden will force the man to orgasm repeatedly until their death. Lily uses the device to both collect a large amount of semen quickly and to dispose of men that have lost their use. The Iron Maiden takes considerable magic to create, so only a few exist inside Lily’s mansion. It’s also believed that one escaped her dungeon into the wild. [From In-game Monsterpedia]
