A bondage training work in which a bondage shop, Ren Nuegami teaches a woman who is interested in SM and bondage, but is anxious and scared when it comes to doing it. A woman who changes into an ecstatic expression as the rope crawls all over her body. Even if the rope is untied, the squirrel cannot be suppressed, and the woman begs for bondage and insertion again. A woman enjoys unprecedented pleasure and cums many times with the squirrel rope of Nuegami Ren who broke the taboo of the SM industry that "the tying teacher is squirming, tying and squirming"!
