Adultery My Mom & the exchange student

[Penetration]

Why is this sound coming from my tent? This sound was made when I was kissing Li Xiaojun, when Sam was hugging his English teacher, and when Sam was showing me a video of him and her girlfriend "playing adult games". A beautiful melody that gets deep into my bones.
　　But why is this sound appearing in the tent now? Could it be?
　　I was startled by my thoughts. I didn't move my body. I stared at Sam in front of me in the dark night. Sam was still sleeping on his side. There was no movement at all. Even his breathing was so even. There was nothing wrong with Sam. Ah, could it be that mom had a nightmare?
　　I looked over at my mother. My mother was also sleeping quietly with her back to me and Sam. Did I hear wrongly?
　　"Stains..."
　　In this quiet and small tent, the sound of water stains rubbing against each other came from a corner. What on earth was going on? I tried my best to breathe, trying to hear what went wrong, whether there was an animal outside the tent or something.
　　"Um...stains..." Sam suddenly moved his body, but the quilt was still covering him, and I only felt his thigh touching my leg again.
　　Strange, why is there that sound of water again?
　　"Snoring... snoring..." Dad's snoring continued.
　　After Sam moved, I continued to listen attentively for a while. Only the breaths of my mother and Sam were intertwined. Could it be that the sound of water stains rubbing just now was my auditory hallucination?
　　Just when I thought I had heard wrongly, Sam's lower body under the quilt touched me lightly again, very lightly, as if he accidentally touched me while sleeping, and then he slowly moved away from me. thigh.
　　No, no, I kept looking at the upper bodies of Sam and my mother. Just now, in the dark night, I paid attention to why Sam touched my lower body so many times. I saw the quilt under Sam moving slightly. Move very lightly.
　　Could it be? What did Sam do to his mother again? As soon as this idea came out, I became nervous again and felt that my breathing had stopped. I looked at the quilt under my mother again, and wherever my eyes passed, my breathing suddenly became thicker, because I saw The quilt covering my mother's body was also moving slowly, very lightly, so lightly that I couldn't see any movement, but I was still paying attention to it and I felt the quilt shaking gently.
