Roshutsu Kanojo.

"My first boyfriend's hobby is to make me expose myself..." Rina is in love. Her lover, however, has a condition. For them to date, she must let him reveal her public shame...
Docile and obedient, oh so voluptuous, and shy!
Let's get her naked in every possible situation!
Cunnilingus while she talks to boy student, public sex next to sleeping man, paraded in flimsy toilet tissue lingerie, an unforgivable act in public stall... revel in her panicked, frightened, AROUSED state of humiliation!
