Adultery My Mom & the exchange student

[Penetration]

　　"How dare you!" Mom raised her chin and looked at Sam again. 
　　"Hey, what are you afraid of!" 
　　"Ah..." Then, I saw Sam pressing my mother on my bed, opening his dark lips and licking her two big breasts. 
　　"Ah... let go of me... gangster..." Mom pushed Sam's strong body uncomfortably. When she couldn't push, she had to give up resistance and let Sam go. I looked at my bed in horror. Except for the room, everything seemed to be around me. It was all eerily quiet. 
　　"Hmm... um... uh huh..." My mother's thick nasal voice brought my thoughts back to the room. 
　　At this time, I saw that Sam had straightened up his upper body, and his mother’s thighs were spread across Sam’s thighs. Under his clearly visible smooth belly was his mother’s thick, dark pubic hair, and his two plump breasts were pressed heavily against his mother’s. Chest. 
　　After Sam wiped his saliva, he held his penis as thick as his arm and gently rubbed it under his mother's thick pubic hair. 
　　"Hmm... Uh-huh... Aha..." Mom looked uncomfortable, holding my sheets tightly with her two little hands, closing her eyes and opening her little mouth, and hummed from time to time. 
　　"Hey...", "Hey..." Sam's buttocks pressed down on his mother's ass, and then he heard a sound like piercing the thick air in the air, and his mother also opened her mouth, dragging out a long final sound. He gasped. 
　　At this moment, I was extremely nervous. I knew that my mother and Sam were having sex again, at home, on my bed... My 
　　eyes suddenly turned into a trance and I looked at the two shaking bodies on the bed, shaking like phantoms.
　　Increasingly heavy breathing and moaning could be heard intermittently in his ears. 
　　"Pah! Pah! Pah!" 
　　"Ah ha... ah... uh huh... um... um..." Mom's panting continued, and the shadow in front of her eyes became solid again, with a black skin pressing against the snow-white body. On the top, two black hands hold two big snow-white breasts, and the dark mouth opens to hold the two dots of cherry red on the snow peak. 
　　I don’t know how long I listened numbly to my mother’s gasping. Suddenly, I saw Sam pick up my mother and turn her over, so that Sam penetrated her mother’s plump buttocks. 
　　Then, a violent and rapid "pop..." sound came outside the window, and my mother gasped repeatedly. I even heard my mother's trailing trill, as if she was about to cry. 
　　After nearly two minutes of frenzied bombardment, the room finally fell into silence, leaving only the mother's two pieces of snow-white plump buttocks and her long and white back that were constantly trembling. 
　　"Mom, let's go to the desk and do it." After Sam said this, he was about to pick up his mother who was pressed tightly against her buttocks by his belly. 
　　"No...there...absolutely not..." Mom suddenly turned sideways and looked towards the desk. Her stunning face was moistened with hot sweat and had some messy hair. Her two big eyes were as tender as water, and her face was flushed pink. One piece, she opened her mouth and said, holding the bed tightly with both hands. Fortunately, she didn't look at the corner...
