Adultery My Mom & the exchange student

[Penetration]

　I saw a faint desire to smile at the corner of my mother's mouth, but then I thought of something, and the shy face turned into a cold look again.
　　"Tonight...just pretend...never happened...from now on..."
　　Mom paused and stood up. Sam still looked at her with an honest face.
　　"Don't let something like this happen again... After all... I am your mother in China."
　　Mom looked at Sam coldly, turned her back to Sam and bent down to pull back her shorts. However, because of this action, she was already white and plump. My buttocks were facing Sam behind me. I thought Sam was going to bully my mother again. Who knew that Sam actually looked at her mother pulling back her shorts in an abnormal manner, although his penis was still so engorged and erect.
　　"Mom, you are so beautiful, you should be an angel from heaven."
　　Sam said behind his mother.
　　"..."
　　Mom didn't reply to Sam, but from the surveillance camera, I saw the corners of her mouth change slightly under her cold expression. I didn't know if it meant happiness or what it meant.
　　"..."
　　After mom put on her shorts, she walked straight upstairs without looking at Sam again. Sam watched his mother walk away, staring straight at her plump buttocks. I knew that Sam’s desire to bully his mother had not died.
　　However, how could I go back and stop it now? I closed my eyes and could only pray that I could return home quickly to protect my mother.
　　"Sam...you African beast..."
　　I cursed my African classmate who lived with my mother at home.
　　Next, the surveillance video showed that after returning to the second floor, the mother went to the bedroom to take out a change of clothes, locked the door and took a shower, then returned to the bedroom and closed the door tightly.
　　Sam closed his eyes and rested in the living room. This guy didn't even pull up his pants. The black genitals were always erect, standing straight up against the ceiling of the living room at home.
　　Not long after, Sam went to the toilet to take a shower. The next surveillance was the first thing I saw. After taking a shower, Sam returned to the bedroom to rest, and then went upstairs to the door of his mother's room. He seemed to say something, because the surveillance was installed in the toilet, which is far away from his mother's bedroom. From a certain distance, I didn't hear what Sam said. Fortunately, my mother didn't open the door for him. Finally, this guy shamefully went to the laundry room to take out his mother's bra, returned to the door of her bedroom, held his erect cock, and started masturbating.
　　After watching the surveillance, I actually felt some inexplicable fear and worry, and also a little bit, inexplicable excitement? My slightly erect lower body didn't think I was lying. Although the thought was fleeting.
　　"I hope I can go back tomorrow."
　　I was praying in my heart.
　　However, what makes me wonder is why after Sam said something in my mother's ear, my mother seemed to have lost the sense of resistance. Instead, it gave me an indescribable feeling.
　　Sam said, knowing soon enough, what could it be?
　　With a trace of uneasiness, fatigue came over me, and soon I fell asleep.
