Gravure model Ria Yamate arrives for an oil massage, unaware that the oil has an aphrodisiac effect. As the masseur moves from her breasts and groin to her pussy, her long I-cup body arches violently through convulsions and huge squirting orgasms. The abuse escalates into deep pounding, restraint in handcuffs, toy play, and finally a threesome. Her body bends into impossible curves as she reveals orgasms unlike anything seen before.
