“mom, i had a hobby like this…” yuuto found hemp rope in his mother’s room. but i’m not confused. i was rather convinced. my propensity to be strangely attracted to the act of tying a woman was inherited from my mother yuka. yuuto, who was worried that he might be abnormal, was relieved to know that yuka was the same. my mother is the same as me if so, my mother should understand this uncontrollable urge. thinking so, yuto decides to train yuka in bondage.
