Chitose, a high-achieving schoolgirl who appears innocent and refined, harbors a dominant sadistic side. She falls for Minato (湊), a handsome and slightly delinquent-looking college student she sees daily on the train. After boldly confessing her feelings and getting rejected, Chitose reveals she has compromising photos of Minato being pleasured and humiliated by women — proving he is a hardcore masochist.

Using this leverage, she blackmails him into becoming her personal submissive. What starts as forced obedience slowly evolves as Minato realizes that being abused and controlled by Chitose satisfies him far more than his previous enslavement to his sister. Through various intense BDSM-style plays, verbal humiliation, and erotic training, the two explore their inverted desires.

In the second part, Minato begins to see Chitose as his ideal woman and confesses genuine feelings. Their twisted master-pet dynamic deepens with rewards, punishments, and escalating sexual dominance. This 2-episode OVA (adapted from Soft Circle Courreges’ visual novel) is a standout femdom hentai that blends blackmail, heavy teasing, foot play, and emotional layers within a pure sadomasochistic romance. Perfect for fans of Do S girls and Do M boys.
