Adultery My Mom & the exchange student

[Penetration]

　I think this may be because midsummer is coming. 
　　After studying for a while and eating dinner, I studied for a while and then two hours passed. Today's study task was very easy. After studying, I fell in love secretly. After secretly kissing Li Xiaojun in the study for a while, Aunt Wen pushed the door in. , Fortunately, we have already sat upright and looked like we were studying. 
　　"Zihan, Xiaojun, eat some fruit." Aunt Wen handed the fruit plate and placed it on the table. I looked at her awkwardly and smiled. 
　　"Thank you, auntie." Maybe my face is still red. 
　　"Giggle...you're welcome, go ahead." Aunt Wen smiled softly and walked out. 
　　After Aunt Wen left, Li Xiaojun and I smiled awkwardly at each other.
　　When I thought about Aunt Wen's words, I always felt something was wrong. I didn't know if Aunt Wen had discovered something, so I had to sit for a while and say goodbye to Li Xiaojun. 
　　When I came to the living room and saw Aunt Wen with an unspoken smile on her face, it made me even more dizzy, so I had to rush home with a blushing face. 
　　When I returned to the familiar doorstep, I finally breathed a sigh of relief. 
　　I took out the key and pushed the door open. The lights were on in the living room, and a yoga class seemed to be playing on the TV in the living room. 
　　I closed the door lightly and walked to the living room. A purple yoga mat was spread on one side of the living room, but I didn't see my mother, father, and Sam. 
　　Maybe Sam went to play somewhere again, and his parents were upstairs. 
　　I shook my head thinking about Sam. 
　　But thinking about that smile again made me shiver again. 
　　I took a sip of water and walked to the bedroom. When I came to the stairs to the second floor, I looked up out of habit. 
　　However, this sight made my heart beat violently. Looking along the dark red stairs, at the corner of the stairs, I seemed to see a familiar flesh-colored cloth thrown messily in the corner.
