Adultery My Mom & the exchange student

[Penetration]

　It turned out that my mother was wearing a thin white sleeveless mid-collar sweater. Because my mother’s skin was so tender, I was still worried about whether she was wearing clothes. But thinking about it, how could my mother be exposed to Sam without clothes? 
　　"Well..." Sam's body was still trembling, but he was much more relaxed than before. 
　　"Mom, can I sleep with you tonight? Sam is very scared." Sam looked up at his mother in front of him, but his hands did not let go of his mother. Instead, he still hugged his mother's slim waist tightly and moved towards him. Sticking on the body. 
　　"Ah...Sam...let go of mom first..." Mom looked at Sam who was close at hand, and seemed to feel that the atmosphere was a bit ambiguous, and she moved her head back. 
　　"No...Mom doesn't promise Sam, Sam will..." 
　　"Bang...", "Bang..." 
　　"Ah...Mom..." Before Sam could finish speaking, a burst of thunder came again, and Sam screamed and tightened his grip. hug mom.
　　"Ah..." Sam hugged his mother tightly, and her mother also screamed, but her mother's scream was not like Sam's fearful voice, but an intriguing shy feeling. 
　　To prevent me from hearing wrongly, I moved the progress bar back to the time when there was thunder. 
　　"Ah..." Sam hugged his mother tightly, and then her mother screamed, giving me a strange and charming feeling. 
　　I stared closely at Sam and my mother who were hugging each other. At this time, I saw my mother's hand reaching down to push Sam's hip bone. However, Sam was too frightened and still hugged his mother tightly. His mother did not Pushing Sam away. 
　　"Um...Sam...let go of mom first..." Mom couldn't push Sam away, so her hand went back to grab Sam's hand. 
　　Looking along my mother's hand, I discovered that one of Sam's big black hands was actually grabbing my mother's butt tightly! 
　　I quickly rubbed my eyes and looked over. Yes, Sam was actually grabbing my mother's butt. Since I had been paying attention to Sam's actions, I ignored whether my mother was wearing pajamas. When I looked, I saw Mom was wearing a pair of gray shorts, very short, like underwear. 
　　Mom's buttocks were already plump, and when Sam's hands grasped them, it was like kneading dough, and the excess buttocks squeezed out from the gaps between her fingers. 
　　"Mom...I'm afraid...I'm afraid...I'll sleep with you tonight, please, Mom..." Sam swayed on his mother like a toddler, and grabbed his mother's buttocks and kneaded them a few times without noticing him. His own outrageous behavior. 
　　"Ah...Sam...you're hurting me...let mom go first..." I saw Sam naturally pinch my mother's buttocks a few times, and my mother actually screamed, but she quickly asked Sam to let go of her. The hands were pushing Sam. 
　　"Ah...I'm sorry, Mom...Sam didn't mean it..." Sam finally reacted and quickly let go of his mother. At this moment, I saw something dangling on the crotch of his white shorts.
　　When I took a closer look, I was instantly shocked. Isn’t this guy’s swaying crotch his penis? He actually got an erection while holding his mother! Could it be that Mom's abnormal scream just now was due to the erection of Sam's penis under his crotch? I pulled the progress bar back to when Sam held his mother tightly in his arms. It didn't matter. In the video, I saw that Sam's crotch was directly pressed against his mother's lower body, which meant that their lower bodies were completely intact. They were all touching, even though Mom and Sam were both wearing shorts. 
　　But after I clearly understood the appearance of Sam's erect penis, I finally understood why my mother screamed with such intriguing and charming feelings the moment she was held in Sam's arms. Mom must have felt the erection under Sam's body. , maybe the penis has already touched a certain part of the mother. 
　　After Sam glanced at his mother, he lowered his head and apologized repeatedly to her, like a child who had done something wrong, waiting for punishment and education from adults.
