The first time I saw my sister-in-law was when Xu Mu went to junior high school. He followed his parents to walk around with their friends' house. His son Cai Ge had just gotten married, Xu Mu called Cai Ge's wife Sister-in-law. Xu Mu thought that his sister-in-law was not outstanding, but her two slender and tight legs were dragging her round ass, making Xu Mu's crotch tight. Although Xu Mu was precocious at that time, she could only appreciate the innocent and cuteness like Xiao Ai on the table, but she could not understand the temptation that her sister-in-law could bring to men's impulse in her mature state. But only so Xu Mu still sincerely admired the pair of lively and jumping guys on her chest, and the pair behind her sister-in-law could drag her.The butt raised up, and the sister-in-law was obsessed with her close clothes, which really made Xu Mu, who was in love with her first love, feel a strain of urine tight, but the pain was filled with the swollen dick, but she couldn't squeeze out a drop of urine when she arrived at the toilet. It was not until now that Xu Mu realized that it was called erection. It was not that several children were tightening to the distance. It was also true that Xu Mu's impression of his sister-in-law became a landscape, a kind of young woman who could make her thoughts and things in her crotch nervous. At that time, Xu Mu lived at Cai Ge's house for a few days. Because of his young age and his sister-in-law's unrestrainedness, Xu Mu enjoyed the infinite scenery until Xu Mu understood some sexual principles, and he used his sister-in-law as a masturbation object.
