Minako has always fantasized about being teased by large groups of people. Her fantasies spiral out of control, driving her to the point where she can't resist and begins masturbating on all fours—an unusual and striking introduction. Hailing from Yamagata Prefecture, she's a fair-skinned married woman whose job as a sports instructor has given her a sleek, flexible body exuding the scent of a lustful female. With a strict no facial exposure policy, she wears a mask throughout, yet beneath it, her ecstatic expressions are impossible to conceal as she endures extraordinary, otherworldly torment. The men tormenting her find their own arousal pushed to the absolute limit, creating a strangely captivating atmosphere in this work.
