[USBA-033] Uniform bondage An innocent body that was bound by my father-in-law and learned the taste of the rope

It was because of the rope that I first learned about the pleasure of sex. The suffering and misery of being tied up sprouts masochist libido. An obscene body that becomes sensitive when tied tightly and gets wet when humiliated. Mahiro peeps into sm sex between her mother and father-in-law. Seeing the ecstatic expression of the mother who is tied up, Mayo who is interested in bondage masturbates. It is scolded and it is made to be scolded for peeping from father-in-law while mother is away. The training advances as a result of it, and Mayo falls to the rope guy ●.
