Risa, a stunning office lady with beautiful legs, catches the eye of her timid, foot-fetishist, male masochist coworker. Obsessed with her thighs and feet, he keeps making mistakes at work. As punishment, he's scolded and verbally abused daily, slapped, kicked, forced into human chair, human cushion, and human footrest positions, and made to endure foot odor and sweat. Used as a personal plaything at the office, his suffering continues until one day he snaps—luring Risa out and forcing her to watch him masturbate while staring under her skirt and at her feet. But when she suddenly wakes up and catches him, she gains leverage. She forces him to confess his foot fetish, his secret love for her, and his true masochistic nature. To prevent her from exposing him at work, she blackmails him into becoming a test subject for the BDSM products sold by their company. Gradually, he falls deeper under her control, descending into complete submission as her obedient servant.
