Adultery My Mom & the exchange student

[Penetration]

　"Don't worry, your mother said everything is fine at home, don't worry about them." Dad patted me. 
　　However, Dad must have thought that I was worried about the impact of the virus on Sam and Mom. He definitely didn’t know that I was worried about the desecration and harm done to Mom by the wolf from Africa at home. 
　　Looking at my father's appearance, I had no choice but to go back to the room to rest in despair. 
　　My father followed my grandparents to the flower fields to weed and farm, and I followed him out to breathe fresh air. My grandparents brought me a lot of fruits, which finally made me temporarily forget about the fact that my mother and Sam were alone at home.
　　After lunch, I went back to my room to rest and thought about the situation at home. I turned on the surveillance camera again, only to see that my home was completely quiet. 
　　I squinted my eyes. Did Sam and Mom take a lunch break? They are not present in the surveillance cameras I installed in the living room, kitchen and second floor of my home. 
　　I switched the monitoring to the second floor alone. After listening carefully for a few minutes, there was no sound. The toilet and laundry room were also closed, and no one was inside. 
　　I looked at my mother's closed bedroom, still a little worried, maybe Sam was in my mother's bedroom. 
　　"Bang!..." Just as I was staring at my mother's bedroom, there was the sound of opening the door on the first floor. I adjusted the surveillance back to the living room on the first floor and saw Sam, wearing a pair of white briefs, walking to the sofa with his upper body naked. He was sitting up, drinking a glass of water in his hand, but staring intently at the mobile phone in his other hand. 
　　Although I was disgusted by the sudden appearance of the black man in the surveillance camera, I was also inexplicably relieved, because if he was not with his mother, she must be resting in the bedroom. 
　　Looking at Sam with a lewd smile on his face, I gritted my teeth in hatred. I really wanted to put a bag around his head and beat him several times to relieve the hatred in my heart. 
　　Sam smiled obscenely at the phone for a while, put the water glass on the guest table, stretched his legs forward, and lay back on the sofa. His right hand actually reached into his white briefs, and seemed to press something inside. After a while, he pulled out the seemingly weak penis from his crotch. The dark penis seemed to be very weak at the moment, and the glans was pulled against the crotch. 
　　I hated it, but even though Sam's penis was weak and weak, it was still thick and long. I looked at the penis in my crotch and swallowed unconsciously.
