Adultery My Mom & the exchange student

[Penetration]

　Sam continued to lick his mother's lower back, sticking out his long tongue, and licking the tip of his tongue from his mother's neck along the spinal cord to her waist bit by bit. . In order to prevent his mother from running away suddenly, Sam's hands still grasped his mother's hips tightly, and tightly covered his mother's buttocks, which were only wearing white lace panties, against his crotch. However, I just thought that Sam walked into the toilet without wearing underwear. So, didn’t mom’s buttocks have unobstructed contact with Sam’s penis? 
　　Sam...I'm going to kill you! I felt like my eyes were full of swelling. What did Sam say to his mother that caused her to react so strongly? I gritted my teeth and continued to look at the surveillance camera on my phone. 
　　"Mom, tell me, what would Dad do if he knew?" 
　　Sam pressed his two thumbs on his mother's jade-like buttocks. As if he wasn't satisfied, he bent down, raised his mouth, stuck out his tongue and licked her mother's ear.
　　"Ah uh... no... no... Sam... mom... mom... please... let go... let mom go..." 
　　Mom raised her shoulders, and her ears that were licked by Sam leaned into her shoulders. 
　　"Mom, what are you talking about? Your underwear is full of water. Let me take it off for you." " 
　　Ah... no... no... no..." 
　　After Sam finished speaking, he hugged his mother's belly tightly with one hand, One hand pulled downwards from the back of mother's buttocks. 
　　Mom exclaimed and looked down at the panties that Sam had pulled down to her thighs. Only then did she come to her senses and clamp her legs tightly around the panties, allowing the white panties to stay on her thighs. 
　　"Mom, look, my hands are full of water." 
　　Seeing this, Sam grabbed his mother's underwear and touched it, then reached out to his mother's eyes. 
　　"..." 
　　Mom took a look, but felt something was wrong again, and turned her head to one side. 
　　"Hey, Mom, you have so much water, as much as your pubic hair." 
　　"Ah... ha... um..." 
　　After Sam finished speaking, the hand pulling the underwear quickly reached into his mother's ass, and then , Mom's white body trembled, and her lower body pushed forward to avoid Sam's movements behind her. However, the mother pressed her lower abdomen forward, and the pair of underwear on her thighs seemed to have given out its strength and slipped down from her thighs. Mom felt the underwear slipping down, and used her hands to pull the underwear up, trying to put it on again. good.
