Adultery My Mom & the exchange student

[Penetration]

"You must be mistaken," I said.
　　"Maybe..." Li Xiaojun wanted to say something but did not continue.
　　"Don't worry, I'm almost home. I'm going to play with Sam. We'll talk tonight." I replied.
　　"Yeah." I didn't reply anymore. I closed my eyes and thought that I must have seen it wrong. There were so many people in the playground.
　　After returning home, I looked at the various styles of clothes on the balcony on the second floor. With the sea breeze, the clothes upstairs were fluttering in the wind.
　　"Summer is here." I looked up at the clear sky.
　　"The semester is almost over, and Sam will go back soon." Suddenly I thought that Sam had been at home for almost a year, and I was used to his presence around me. He was about to return to South Africa, and I couldn't help but have a strange feeling in my heart... I glanced at my phone
　　. , it was past one o'clock in the afternoon, Sam should be taking a nap at this time, thinking, I walked along the outside wall of the house to my and Sam's room. The curtains were opened inside, and Sam couldn't be seen. He should be in the living room, and I returned to the door. , take out the key, open the door and go in.
　　Hearing the sound of the TV playing, I closed the door and walked in barefoot. However, what I didn't expect was that at the bottom of the stairs to my parents' room on the second floor, a pair of Sam's slippers were casually thrown away. There, there is a towel at the corner of the stairs on the second floor. Could it be that mother asked Sam to do housework? Sam, oh Sam, must have made his mother angry, asking her to do the housework for him again. .
　　I returned to the living room, and there was no sign of Sam on the sofa. There was only the sound of the TV series, "Where is Sam?" I thought to myself, thinking about sending a message to Sam.
　　"Um……" .
　　Suddenly, a groan came from my mother's upstairs. I frowned, looked back at the second floor, and walked towards the second floor.
　　The sound of a TV series is playing in mom's room. Is mom watching TV? .
　　"Ah..." Another moaning sound came from somewhere on the second floor. Who was there? I became nervous and walked slowly to the second floor, but my mother's room was closed.
　　"Um...oooo" a strange sound came from my mother's room, as if there was something in her mouth.
　　"Papa... um... ah... um..." It was my mother's voice. She seemed to be vomiting? There is also a snapping sound.
　　How is it possible? A terrifying thought occurred in my brain. It's impossible.
　　Thinking, I held my breath and approached the door of my mother's room, my ears almost touching the door.
　　"Um...ah...huhu"
　　"Is it delicious, Mom?" It was Sam's voice, but why did he ask his mother, is it delicious?
　　no! Why is Sam in Mom's room? ! At this time my heart was beating rapidly.
　　"Um...don't...ah..." Mom didn't reply to Sam, sounding like she was eating something big.
　　"Hiss!" Sam yelled, but it was not a cry of pain, but a moan of pleasure?
　　"Zi, Zhen, Zhen..." The sound of swallowing something continued to come from my mother's room.
