In the women's restroom, they become human toilets, engaging in rear-mounted cowgirl sex. Ultimately, an invisible molester army is formed, using an elevator to gang rape schoolgirls in a continuous series of lewd developments. Whenever you sense something lewd, rest assured—an invisible man is surely there!
