I was ordered by a bully to disguise myself as a girl and sneak into the girls' locker room! The girls started changing without even noticing me! I could watch them change as much as I wanted! It was heaven! I thought that... but then I got an erection at the sight of the girls' underwear and they found out I was a guy, and that was bad! But instead of getting angry, they said, "If you're watching us, show us yours too!", and it turned into an unexpected harem development! I was supposed to be treated like a pervert and be abused for the rest of my life, but somehow I got a super lucky harem experience in this divine development! I'm grateful to the bully who gave me this tough mission!
