Overwhelmed by work-related stress, office lady Maron Natsuki visits a women-only esthetic salon. Drawn in by its special treatments, she gradually becomes addicted. Maron spends all her savings and maxes out her credit cards, yet cannot quit the salon. Eventually, she starts working as a bunny girl at a lounge to afford more treatments. Lacking natural motivation, Maron is pushed to extreme limits by senior bunny girls—forced to grovel naked on the floor, clean floors bare-assed, masturbate on command, and serve customers as a sex slave. Still, lured by the reward of intense, pleasurable sex with the esthetician, she continues working every day as a perverted bunny girl. Here begins the story of Maron's intersecting agony and desire.
