The opening scene in Cute Demon Crashers is a bored, horny, virgin college girl who’s home alone during spring break. Suddenly three incubi and a succubus, male and female sex demons, appear out of a portal in her hallway. The player is then faced with one question: how does the virgin react? (NSFW content warning.)
