Adultery My Mom & the exchange student

[Penetration]

My heart seemed to have stopped beating at that moment. Sam was still slowly moving his butt back and forth, very lightly, but the sound of water-stained friction came from under him little by little. And covered in the quilt, I felt that the lustful smell was getting stronger and stronger.
　　Impossible, it must be Sam, the pervert, who is jerking off to Mom. Mom, hurry up and scold Sam. Hurry up and kick Sam instead. However, I didn’t even see Mom’s reaction. Instead, she let me watch. Sam's butt slowly increased its shaking motion and speed.
　　"Boh...stains...boh...stains...boh stains..." The sound of water stains rubbing against each other became faster and faster.
　　At this time, I actually saw Sam slowly lift one thigh. No, Sam was sleeping with his pants on. There was no sign of taking off his pants, but he didn't stop moving his butt back and forth, and kept pushing towards his mother. Go, wonder, is Sam really masturbating to his mother?
　　"Ah..." With a muffled groan, I saw Sam's body that was lying on his side suddenly lay flat on his back, and his lower body was immediately covered by the quilt. Then in less than a second, I Under the quilt, I saw Sam's dark, thick and long penis being pulled out from under my mother's buttocks, which was facing away from Sam. Because it was too dark, I didn't see whether Sam had taken off his mother's pants. I just watched. His thick and long penis changed from facing my mother's ass to facing the quilt, pushing the quilt up high, and then streams of thick white semen shot out in the quilt. I saw those A large amount of thick white semen fell on his black belly, and some even flowed onto my thighs.
　　At this time, Sam slowly pulled away my quilt, and I quickly closed my eyes, pretending to be sleeping soundly. Sam looked at me for a while, and then covered me gently.
　　Then, I saw Sam under the quilt, his hands slowly pulling his long and thick penis back into his pants.
　　Damn it, Sam's cock was sticking out of his zipper and I said why didn't he take off his pants.
　　Then he slowly lifted the quilt, and I still rubbed against the undulating quilt and saw that Sam's mother on Sam's side didn't make any movement and seemed to be sleeping soundly.
　　Fuck you Sam, you actually masturbated to my mother. I was angry but I didn’t dare to express it. It turned out that I had been smelling his cock under the quilt and masturbating. Sam is a thief... I hate it, but what can I do? We have to find opportunities to prevent Sam from having too much contact with his mother, that's all.
　　Sam, the thief, actually shot a plane at my mother. If my mother knew about this, hey, just wait to pack up your things and go back to South Africa.
　　My mother's pretty face was red, her eyebrows were raised and her eyes were stern. I felt a lot more at ease. But this Sam actually dared to masturbate to my mother. This was beyond my imagination. My mother is really charming, but she is ours. Mom, how could Sam do this...
　　I could no longer stand the disgusting, rich smell of black semen in the quilt. I pretended to be hot and stretched my head out. In the darkness, Sam was breathing with his two big fat intestines open. He looked very I fell asleep comfortably and comfortably, damn you Sam, you are really not a fucking human being, even if you masturbate in front of your mother, you can still sleep so peacefully, damn it! .
　　Hate returned to hate, but sleepiness never let go of anyone. I fell asleep in a depressed mood.
　　The next day, I woke up early for some unknown reason. I heard my parents and Sam breathing evenly, and then I saw Sam take off the quilt at some point, and then I thought about what he did last night. I even started to hate him a little bit...
　　Just when I looked at Sam fiercely, my mother's back appeared in my peripheral vision. She was wearing a suspender skirt on her snow-white back, and further down, because Sam kicked the quilt away inadvertently, I saw that the hem of my mother's skirt was exposed on her plump and round buttocks, and her slightly see-through flesh-colored underwear was looming. The white and tender buttocks were clearly visible inside the flesh-colored underwear.
　　Mom, she is so beautiful. Looking at my mother’s snowy back and round buttocks, I consciously made such a sound in my mind.
　　What the hell am I doing, that’s my mother! I secretly cursed myself for not being human! .
　　I glanced at my mother's back. No, I suddenly thought of a very serious problem.
　　Mom slept in the suspender skirt she wore last night?
