Here is an idea anyone may use. It's in the Equestria Girl universe. A mysterious perverted man, who likes to play games with nude girls. He kidnaps the Mane 6(if you want, you can add Sunset Shimmer in as well), strips them all naked, and traps them in a place(like Canterlot High at night) where they have to play his rules, in order to escape(with or without their clothes). Please comment on this page, or my user page if you want to use this idea.
