Reiko, a beautiful office worker who works at a listed company in Tokyo, had a boyfriend named Shigeki who lives together. He was a pimp-like man who spent his days playing pachislot every day without doing a good job. Reiko, who has a gentle personality, obediently listened to what such a boyfriend said.

Wondering what she was doing, she shifted her head and found, to her surprise, a sinister "chastity belt" was attached to her crotch...!
