Adultery My Mom & the exchange student

[Penetration]

"Zihan! Sam!" As Sam and I were about to enter the college, a sweet and soft cry made Sam and I stop and look sideways. 
　　The morning breeze was mixed with a little dryness, blowing a few dead leaves that had fallen on the ground, and a tall and slim girl ran towards us. 
　　He has a young and youthful standard oval face, with translucent white skin, and the black ponytail tied behind his head is swaying randomly as he runs. 
　　The visitor is none other than my girlfriend Li Xiaojun. She is wearing a bright white short-sleeved high college uniform today. Her running body makes her round breasts sway up and down. Under her light blue long college pants, she wears a pair of white Adidas shoes. sports shoes.
　　When she ran to me, the dry and cool summer morning breeze brought a burst of fragrance, which is the unique body fragrance of girls. 
　　Looking at Li Xiaojun, I don't know why she chose to do that kind of thing with Sam, a black man. She obviously has better choices. 
　　"Let's go, we're going to be late." Li Xiaojun looked at me tenderly, and that sweet smile seemed to make me bathe in the sunshine that filtered through my fingers under the shade of the trees in midsummer. 
　　If it weren't for those videos, maybe what I see in front of me would make me so happy that I feel elated. 
　　"Hmm..." I responded to her nervously. 
　　"Squad leader, what do you plan to have for lunch?" Sam said, walking on Li Xiaojun's left. 
　　"Well...I'll eat whatever you guys eat." Li Xiaojun politely replied to Sam. 
　　However, in my opinion, this is just Li Xiaojun performing. 
　　"Hehe...that's best." Sam smiled. 
　　The first class in the morning was the math class of class teacher Zhang Min, so she held a class meeting by the way. 
　　Today, Zhang Min is dressed very sexy, with long, slightly curly hair. She is rarely seen wearing a hip-hugging skirt and black stockings. Under her slender legs is a pair of bright black high-heeled shoes that are at least 10CM, and her proud C+ breasts are supported. The shirt is all white, and he seems to be fatter than before the lockdown. 
　　What makes me even more puzzled is that Zhang Min doesn't have the same intimacy with Sam as before. I even felt that Zhang Min didn't even look at Sam during the whole class. 
　　Zhang Min is afraid, or in other words, she is avoiding Sam's gaze, but why is this? 
　　"Zihan, did you know? The head teacher is getting married." After Zhang Min's class, Sam followed Zhang Min out of the classroom. 
　　Just when I was wondering about Zhang Min's change, Li Xiaojun, who was sitting next to me, secretly said to me.
　　"With that PE teacher?" I vaguely remember that the PE teacher in the junior high college was not a good person. When Li Xiaojun and I went to the beach to play, we met the PE teacher having an affair with the English teacher. Another time, I followed him. Sam discovered that the physical education teacher was having sex with the English teacher in the storage room at the back of the college. To my surprise, Sam went to compete with the physical education teacher for the English teacher’s mating rights? Although the physical education teacher lost in the end, I still remember Sam asking me to take his cell phone to film the competition.
