Adultery My Mom & the exchange student

[Penetration]

After doing my homework for a while, I saw Sam stand up and look at me with two round eyes on his big black face. 

　　"Zihan, what time is it?" Sam looked like he wasn't quite awake yet, rubbing his eyes with two black hands, 
　　"It's almost 10 o'clock," I replied to him, 
　　Will Sam tell me that he went to the second floor to seek protection from his mother because of thunder last night? 
　　"Oh, then I'll get up and wash up, and we'll help mom cook later," Sam said, got up and went out, 
　　Help mom cook? Although he didn't tell me that he went to see his mother last night, his current behavior is a bit like
repaying mother for holding him to sleep and protecting him last night, 
　　Still having a conscience, I looked at Sam going out, smiled, and continued to do my homework. 
　　At 11 o'clock, Sam and I were in the kitchen helping mom wash and chop vegetables. Mom came down from the second floor calmly, with a
rosy face and an indescribable tenderness in her beautiful eyes. Mom didn't tell me about Sam's incident last night. Whatever happened,
it would be embarrassing for everyone to tell it, and Sam also wanted to save face. If Sam was frightened by the thunder last night,
he would definitely not be happy, even though that was the fact. 
　　Today, my mother is wearing a pair of gray light casual cotton trousers and a dark gray bottoming camisole. Her
two plump and white breasts are proudly erect in the camisole, and she wears a silk collarless pure dark blue jacket. ,
her long hair is still neatly tied back with a hairpin, 
　　The mother in front of me looks virtuous, gentle and beautiful. If I hadn't been a boy and 16 years old, I
would have rushed up to hug her. Thinking about it this way, Sam is really thick-skinned, but he can't help it. Some people
I am really afraid of thunder. 
　　We had lunch, and Sam rushed to clean up the housework. Mom had to sit on the sofa for a while, looked at
Sam doing the housework, sighed, and went upstairs to rest. 
　　Sam was washing dishes in the kitchen, so I had to pick up my phone on the sofa and scroll through TikTok, 
　　Inadvertently, Douyin pushed me another Douyin video shot by "Mumu Xizi". The video showed a row of small trees growing lushly
outside no copywriting. I didn't know what it meant. Maybe my mother was just naive.
I think the landscape is more beautiful after the rain. 
　　After a while, Sam washed the dishes, came over and sat down next to me, picked up the fruit on the table and
put it into his big mouth. 
　　"Sam, you're awesome, learn to show off," I winked at Sam, 
　　"Hey, I just think my mother is working hard, please help her with the housework," Sam said while watching TV, 
　　"That's right, but Sam, you have to give me a chance to help mom, otherwise you would have done it all," I rolled my eyes at
him, 
　　"Zihan, don't you do what I do? We are brothers, both good children of our mother. We
grew up drinking mother's milk," Sam looked at me and said to me seriously, 
　　"Okay, thank you Sam, I have always regarded you as my brother," I replied to him seriously, 
　　No, he has never drank my mother's milk. Is this how South Africa expresses feelings? It should be that
now I'm not too surprised about Sam's weird words or behaviors.
