Breaking demons (Pixiv Fanbox)

Demons are notoriously hard to get to. Most of them are used to an eternity in damnation already, so what could the dungeon possibly offer that breaks their spirits? The answer is neverending pleasure. Even the most powerful succubi will eventually get overwhelmed with pleasure and emotion if you give them strong enough aphrodisiacs. Another piece of advice is to let machines handle the job. Unless the trainer is also a succubus, it’s almost impossible to find someone with enough endurance to take on this task. Hooking them up to some nice devices and leaving them alone while nobody pays attention to them being ravaged by machines is just a nice little extra~
