Recently, Miori, who has been worried about her body line, asks her husband to introduce her to Oshima, a beauty instructor.She is completely taken care of by his polite teaching, but...Oshima, who has an abnormal propensity to take pleasure in humiliating her woman, takes advantage of her and binds her whole body.She can't move, and she even shaves her hair against Miori, who is writhing in shame as she exposes her crotch.Her crotch that became her slippery, the rough rope that tightly binds her whole body, her new pleasure begins to wake up inside her.
