Adultery My Mom & the exchange student

[Penetration]

　After Li Xiaojun and I got on the bus to her house, Sam grinned and waved to us. I know that Sam sometimes doesn’t know where to go and comes home very late, so if he doesn’t go home or where to go later, I'm not worried about playing. 
　　I looked back at Sam, who was still standing on the bus stop. This guy had grown a lot taller. My current height of 1.76 meters was actually a head shorter than him. This guy must have grown to 1.8 meters. 
　　What puzzles me the most is that not only does Sam stand taller, but he also has a lot more muscles on his body, making him look stronger. He really looks like a standing Donkey Kong. 
　　As the back of the bus got farther and farther away from the platform, in a daze, I seemed to see his dark face smiling at me sitting in the car. I winked and looked again, but I saw Sam had headed north toward me. 
　　I don’t know if I saw it wrong, but even if I saw it wrong, I always felt that that smile made my face numb and covered with goosebumps.
　　Why do you feel this way? I frowned. 
　　"What are you looking at?" Li Xiaojun's warm hand gently caressed my goosebump-covered hand. 
　　"It's nothing, I'm a little embarrassed to always go to your house for dinner." In order to forget that feeling, I smiled back to Li Xiaojun. 
　　"Giggle...are you a pig? How much can you eat? Besides, my mother really likes you to come and study with me." "Really?" "Really...", "Really...", 
　　" 
　　Really ...", "Pig..." and Li Xiaojun laughed all the way. When we arrived at her house, Aunt Wen was cooking in the kitchen. After saying hello to Aunt Wen, we went to the study room to start studying. 
　　I have to say that adults are becoming more and more fashionable these days. The few times I have been to Li Xiaojun's house, I always see Aunt Wen dressed very coolly, just wearing a white thin vest and a pair of shorts that are short to the top of the thigh. I am embarrassed to stare at her. Watch Aunt Wen. 
　　Of course, the same is true when mom is at home these days. Mom’s figure is even better than Aunt Wen’s. In addition, mom has started doing yoga in the living room these days, so the white patch of mom’s chest is exposed to our eyes from time to time. It’s so short that Wearing shorts at the base of her fair-skinned thighs, when I raised my eyes, I accidentally saw the fullness of my mother’s crotch, which made me feel guilty. Fortunately, Sam was chatting with his father and didn’t look to one side while mother doing yoga.
