A secret footage of a poor boyfriend filming his girlfriend's masturbation in order to get some pocket money and selling it to an AV production company without permission

When they say to their boyfriend "Show me masturbation," the girls are embarrassed, but masturbating in front of the camera. In search of money to play, my boyfriend sold me a secret masturbation video. They believe in their boyfriends, so they probably don't think this video will be sold to an AV production company! They are exposed to the public's embarrassing private masturbation without even realizing it.
