Adultery My Mom & the exchange student

[Penetration]

　　"Zihan, I don't have to take the comprehensive exam in the afternoon, my final exam is over!..." Sam said happily. 
　　"That's it. Okay, then where are you going this afternoon?" I looked at Sam who was frustrated, and Li Xiaojun looked at us silently like a docile cat. 
　　"You and Xiaojun go to eat. I...should I go home or go play? I have to think about it." Sam's look of being unable to make a choice made me very unhappy. 
　　"It's up to you, then I'm going to eat." I looked at Li Xiaojun and then walked to the cafeteria. 
　　"Wait for me..." Li Xiaojun called softly behind me.
　　"..." I turned around and looked at Li Xiaojun, who was running towards me. 
　　She was actually able to run, it seemed like Sam didn't give her those underwear to wear today. 
　　"Hey, Zihan, have a good exam this afternoon, I'll wait for you at home..." Sam looked at his phone, waved to me, and walked towards the college gate. 
　　Li Xiaojun came to my side and followed me to the cafeteria. 
　　At 12:30 at noon, ever since I found out that Li Xiaojun lost her virginity to Sam last year, I felt disgusted with her, even though she kept talking to me shamelessly, as if nothing happened. 
　　"Zihan, show me your summary." Li Xiaojun looked at me without blushing or heartbeat. 
　　"Um... we'll know about it in the afternoon class meeting." I glanced at her and said a little coldly. 
　　"Zihan, you are so fierce..." " 
　　..." Li Xiaojun actually acted coquettishly towards me, but I just chose to ignore it. 
　　I wrote the summary report all night, so how could I show it to her? 
　　Thinking about it, I reached into my collegebag to get it. 
　　But I couldn't find it no matter how hard I looked, I was a little panicked now. Could it be that I was in a hurry this morning and forgot to put it in my collegebag? I recalled that last night I finished writing and put it on my desk before going to bed. When I woke up this morning, I seemed to just pick up my college bag and go to college. 
　　The summary report is at home! 
　　I immediately looked up at the clock hanging on the classroom wall, it was 12:50 noon. 
　　The afternoon exam starts at 14:30, and I still have time to go back and get the report. 
　　Li Xiaojun looked at me and didn't care to continue reading her book. I walked to the gate of the foreign college minding my own business.
