Pls gurl, everybody knows that the girl's changing room in hentai-land is as secure as Fort Knox and instantly renders any copulating inhabitants undetectable to all 5 sense and any other form of surveillance known to man (radar, microphone, or camera).
Note: Masturbation in a girl's changing room, on the other hand, is like sending out a brightly flashing, hormone-spewing, SOS signal flare begging a person of the other sex to bang you.
Note Secundus: This only applies in vanilla hentai-land. If you are in rapey hentai-land, you are so fucked (both figuratively and literally).
