A husband who hasn't dealt with me for the past few months. - Hibiki, who suddenly sees his brother-in-law's big dick at his husband's parents' house, has a wonderfully towering cock stuck in his head ...- Hibiki and her husband, who returned home to her husband's parents' home, Otsuki, are told by her brother-in-law that their parents are traveling. - Inconveniently, Hibiki had never met his brother-in-law, but he was relieved because he looked kind. - The husband told her brother that he would stay at his parents' house for a while without his parents, and the three of them started living for several days. - Hibiki visits her brother-in-law's room while taking a nap, and reaches out to her crotch bulge that seems to pop out at any moment. - Appearances ○ Po is not completely erected and is irresistibly included in the mouth. - The gradually swelling meat stick was like a weapon, and Hibiki couldn't stop sucking.
