S1 No.1 Style presents "First Bondage," a hardcore tied-up torture film starring Mikami Yua! The popular idol's voluptuous body is forcefully bound, stripped of all freedom. Her tightly constricted body reacts with extreme sensitivity, beginning the path to climax. Stripped of her idol status and treated merely as a plaything sex slave, surrounded by crimson ropes, her lewd, wet pussy is brought to orgasm again and again. Her completely dominated body is repeatedly raped, surrendering entirely to the pleasure. The concept of [Idol = Plaything Sex Slave] is the ultimate appeal of this work.
