Adultery My Mom & the exchange student

[Penetration]

　"Okay, just here." 
　　"Pop!" Sam slapped his mother's butt. 
　　"Ah..." Mom then gasped in a habitual way. 
　　"Lift your butt a little higher." After Sam said, he saw him pick up his mother's butt and lift it up. 
　　He dragged his mother's body and changed the direction, so that his and his mother's buttocks were facing the window. 
　　"Ah..." Sam's cock pushed into her mother's ass, and her mother gasped again. 
　　Then, just like the previous piling, my mother gasped one after another, as if she was afraid of moaning too loudly, so she picked up my quilt and covered her head. 
　　The moaning suddenly became much quieter.
　　My mother's buttocks were pushed up high, and her two tall thighs were spread apart to both sides. Sam's dark cock was clearly inserted into my mother's vagina and was clearly exposed to my eyes. 
　　As the penis went in and out of her vagina, I even saw that Sam's dark penis was gradually dyed milky white by some kind of liquid. On my mother's vagina, the two thick labia had already become thick. It was all white, and some thick white liquid even started to flow down to the pubic hair under the clitoris as the cock was grinding. 
　　Is the thick white liquid slowly grinding out the leucorrhea from my mother's vagina? Or another liquid? I don't know, I just know that I feel like I'm going to die. 
　　As time goes by. 
　　The sound of "papa..." became more and more urgent. Although her mother covered her head with a quilt, her moans became louder with the rapid "papa" sound. 
　　Just when I thought Sam was about to ejaculate, he stopped and quickly pulled out his penis regardless of my mother's trembling body. Then my mother collapsed on the bed like a deflated rubber ball. 
　　However, just as I was looking at what Sam was going to do without knowing why, he actually took the dick that was dyed milky white and inserted it into my mother's asshole! … 
　　I looked at it in shock, covering my mouth with both hands, feeling like I was about to scream. 
　　Sam, are you going to...fuck Mommy's ass? Mom fucks Sam in her ass? 
　　I watched in disbelief.
