Adik iparku yang tiba-tiba menikah lagi cerdas, polos, dan murni. Tapi sebenarnya? Yukino Nagasawa

My stepfather remarried and suddenly I had a JD sister-in-law. She is a serious woman with excellent grades, unlike me, and she is supposed to take care of my exams, but in fact, she is a muscular skeleton who is curious about sex. I couldn't resist the temptation of my sister-in-law and devoured her body.
