Adultery My Mom & the exchange student

[Penetration]

　The point is not this. The point is that my mother saw Sam standing up and what Sam was holding. My mother was stunned there, motionless. I saw my mother's expression was full of shock, and one of her tender hands gently He covered his mouth and stared with his big eyes at Sam, who was standing up and masturbating in the living room with his back to him.
　　I looked at the time. It was 15:20 in the afternoon. At this time, Sam must have thought that his mother was taking a nap upstairs. However, her mother usually took a nap at this time. I don’t know why she came down at this time. Maybe she wanted to Take something, anyway, she saw Sam's outrageous and weird behavior.
　　My mother covered her mouth for a while, and I saw her plump breasts swaying a few times due to the emotion of breathing. At this time, my mother put down the hand covering her mouth, but she did not leave and kept looking at Sam from behind for several minutes.
　　Sam on the sofa didn't realize that his mother was already behind him. While looking at the phone, he quickly held his cock to bring more stimulation. I saw that my mother's expression at this moment was no longer as shocked as before, but looked at Sam with a look that I didn't understand. What was most difficult for me to understand was that my mother's slender hand actually squeezed it unconsciously. Her thighs were exposed outside her shorts.
　　"Ah~ Mom, I love you!"
　　I kept looking at my mother in the surveillance corner and forgot to look at the situation on Sam's side. After he shouted a word, his glans doubled in size in an instant, and he was filled with thick semen. He ejaculated at the guest table in front of him, stream after stream, and the table in the living room was covered with Sam's semen.
　　When I looked over at my mother, she unexpectedly covered her mouth again. In order to see clearly, I pulled back the progress again. When the monitor sounded again, "Ah~ Mom, I love you." !” When Sam said this, her mother’s body trembled visibly, and her plump breasts wrapped in white cool short sleeves swayed unconsciously. Then, my mother's tall nasal cavity closed and opened again, and her two beautiful eyes were enlarged and stared at Sam who was ejaculating crazily in front of the guest table in disbelief.
　　After Sam finished ejaculating, his mother slowly stepped back and walked upstairs like a thief. Sam didn't realize that his mother had just witnessed the entire process of his ejaculation. He pulled up his pants, took out the tissue, wiped the semen on the table, and threw it into the trash can. Then Sam stretched his body comfortably and walked to the bedroom.
