Two M slaves are restrained and subjected to a relentless series of torments leading them to the peak of pleasure. The first is a gravure aspirant, photographed in bloomers and swimwear, who suddenly finds her hands and legs bound, an anal vibrator thrust into her ass. Multiple hands move over her body, concentrating attacks with two electric massagers and rotating stimulators. When she screams, "I'm gonna come!", the torment stops, revealing the men's cruel refusal to let her climax honestly. Her entire body slick with oil, she undergoes erotic massage, growing increasingly aroused and begging for a cock—only to be denied. Instead, she reaches squirting orgasm through skilled hand-fucking. Bound with legs spread wide, her pussy and ass are assaulted by a thick electric vibrating drill and a piston dildo, writhing and squealing "Hii! Hii!" as her whole body grows hypersensitive. Finally granted the sight of a real cock, a delighted woman appears—when she's fucked raw and creampie in her school swimsuit as desired, she falls into blissful ecstasy. The second woman is placed in a semi-hypnotic state during the director's interview, tied down on the bed, and teased with various sex toys before being taken with bareback creampie. Her body becomes extremely sensitive, repeatedly sent into oblivion by finger-fucking and a thick electric piston dildo, until she rolls her eyes back in euphoric surrender. (Oni Gangbang Way)
