Wakana hates men, but after her father disappears and leaves a debt behind, she is confined for ten days in a gangster father-and-son household and forced to work as their servant. They demand sexual service, assault her in groups, and make her climax repeatedly until she discovers pleasure she never knew. Used as a relief maid, she is penetrated whenever either man wants to cum and pounded until excessive orgasms overwhelm her. Immersed in constant pleasure, she eventually begins moving her hips on her own and cumming with a blissful expression, conditioned into total obedience as the pair’s personal sex toy.
