Adultery My Mom & the exchange student

[Penetration]

"Sam! Sam! Late!"
　　"Ah! Are you late?!"
　　Sam quickly stood up and looked at me with widened eyes.
　　"Haha, there is an exam today! Get dressed and go!"
　　I felt very happy when I saw Sam like this.
　　"Oh, it turns out to be an exam! Ah ha..."
　　Sam yawned a long yawn, as if he hadn't slept enough.
　　"I said Sam, you slept more soundly than me, and now you are actually yawning. Are all you black people so lazy?!"
　　Seeing Sam like this, I felt disgusted, and then thinking about the scene of Sam bullying my mother, I felt a little... Inexplicable anger.
　　"...Hmm...No, it's probably because I went to bed very late last night. Ah..."
　　Sam yawned heavily again.
　　"Haha, I told you not to talk to your girlfriend too late!"
　　"Hey, I'm sorry, Zihan, you found out again. I really missed my girlfriend last night and slept with you, so I I jerked off to her photo!"
　　Sam scratched his head in embarrassment, Damn it, this Nico jerked off to me, disgusting nigga.
　　"Ah...haha...you are awesome!"
　　I was too lazy to talk to him and went out to wash up.
　　To my surprise, my mother actually got up and made breakfast for us in the kitchen.
　　My mother's back is facing me, her hair is curled up and held with hairpins. Under her snow-white neck is a soft white back wearing a light blue camisole. Even after watching her back for so many years, I still feel She has a kind of unworldly beauty, slender figure, slightly raised hips, especially the pair of long thighs under the gray shorts. The skin of the thighs is too fair, and the veins in the flesh are clearly visible.
　　"Mom, morning!"
　　I walked to the toilet. Why do I always feel that my mother exudes an irresistible smell, that kind of unexplainable smell? Maybe she is my biological mother, so I feel very strange. .
　　"Hurry up and wash up and come have breakfast! If you can't stand it, I'll tell you to go!"
　　Mom's voice was a little gentle this morning, but then she slowly became stern. Mom was really surprised.
　　"Oh...Dear Mommy! Thank you for getting up so early and making breakfast for me!"
　　I was washing in the toilet when I heard Sam's voice coming from the kitchen.
　　"Okay, go wash up!"
　　Fortunately, my mother's attitude towards Sam was still so strict, which made me feel at ease. At least even if those two things happened, I believe it was Sam who forced her, at least my mother wanted to More than me, otherwise with her attitude and temper, Sam would definitely go directly to jail.
　　Sure enough, Sam walked in obediently, although there was a smile on Nico's face that was somewhat unpredictable to me.
　　We finished breakfast and caught the bus to college to take the exam. When I was having breakfast at home, I took a look at my mother's face, but she looked like a spring breeze. Her face was slightly rosy, her beautiful eyes were filled with mist, and her mouth was smiling, and she was very gentle. When she was adding porridge to Sam and me, there was something expressive in her movements. The strange feeling that never comes out is in my memory. I remember that when my mother gave me this feeling, it was before I entered junior high college.
　　I don’t know what kind of feeling my mother gave me. If I wanted to use an idiom to describe that feeling, it would be charming.
