My husband, who tends to be away from work alone, was a mandarin duck couple who burned violently with his mother, Yu, every time he returned home. Until my son peeks at me. The crotch of the removed son swells and becomes conscious of the mother. One day, when my mother came home with a drink, my son played a trick. After that, the physical relationship continues like every day with his son who is relentlessly approaching, leading to an affair without an exit.
