You play as the practitioner, gradually “developing” the innocent college student Haruna under the guise of massage—a full-animation NTR/corruption simulation. Choose which body part and technique to use, watch her reactions, and build trust. Treatment starts innocently—shoulders, neck, back—and unlocks step by step toward lips, chest, and beyond. Each visit has dialogue; treatment scenes are fully voiced. Climax and ejaculation scenes included.

Lines and animation change with her corruption level, as her proper facade peels away and she begins to want it herself—progress you drive with your own hands.
