Adultery My Mom & the exchange student

[Penetration]

　　Chapter 40
 
　　Thinking that my mother would be getting off work soon, I hurried back to the living room and kitchen to clean up the house. Then I went back to the bedroom to wipe away the water stains that Sam had made on the desk, chair and floor. I passed by the bed and looked at the stains. While Sam was sleeping, I was really angry. Thinking that he was about to return to Africa after his exchange period was over, I calmed down my depression.
　　"Sam, mom is about to get off work, you're still sleeping!" I walked over to him and kicked the quilt.
　　"Ah?! Mom is back? I'm done!" Sam's eyes widened and he stood up reflexively, the penis in the black sweatpants shaking a few times.
　　Seeing Sam's panic, I was really proud of myself. Although Sam had violated his mother before, it must have been because Sam forced his mother to do it, but after the slap his mother gave him, Sam was obviously a lot more honest.
　　"Don't panic, mom isn't back yet." I smiled slightly, with the corners of my mouth turning up in disdain.
　　"Ah?! I thought Nami...mom was back!" Sam paused.
　　Strange, Sam said the word Nami again, does it mean something?
　　"Sam, I woke up and found water on and off the desk. Did you touch the water glass?" I frowned thinking of those water stains.
　　"Hey, Zihan, I'm sorry, maybe I bumped into him and didn't pay attention!" Sam looked apologetic, but the corners of his mouth turned up slightly.
　　"...be careful next time, if mom sees it, you will get some good results!" I smiled sinisterly.
　　"Well, I'll pay attention next time!" Sam smiled happily, what's so funny about this.
　　Seven o'clock in the evening, in the living room.
　　"Zihan, why isn't mom back yet? Why don't you call and ask?!" Sam said anxiously.
　　"We should be home soon!" I called my mother.
　　"Hey! Zihan, mom has to work overtime at the company tonight. You guys can order takeout." Mom answered the phone.
　　"Well, Mom, you come back early!" After hanging up the phone with my mother and telling Sam that my mother was working overtime, Sam smiled slightly, but I always felt that he looked very uneasy.
　　Ten o'clock in the evening, on the sofa in the living room.
　　"Zihan, it's too late for mom tonight. Will you go drinking again? You can call and ask." Sam looked at me and said.
　　Sam was actually more worried about my mother than I was, and I felt a little bit inside.
　　"...beep...beep..." Mom didn't answer the phone, and I didn't feel very good immediately. Mom might still be busy, I thought.
