Adultery My Mom & the exchange student

[Penetration]

Hmm... But it should be a bit dangerous, so I'd better stand on the shore. I looked pitifully at the English teacher's husband who was sitting on the shore and looking into the depths of the swimming pool.
　　Let me help you take a look, I thought, diving into the pool and swimming deeper.
　　This open-air swimming pool is not small. I swam for a while before I came to the inside of the swimming pool. I could only use the peripheral light from the front to see clearly the environment inside. In the somewhat dim environment, there were actually people swimming in it. I saw I looked around, but I couldn't see Sam. Maybe it was too dark here, and with his dark skin, it would definitely be difficult to find him.
　　I swam for a while, and finally saw two vague figures swimming in the innermost corner of the swimming pool. I slowly approached and found that they were Sam and English teacher Sun Xiaoxiao.
　　But their behavior at this time made me a little confused. The English teacher's snow-white arms were paddling in front of her, and Sam was behind her, looking like two frogs hugging each other, but I didn't look at it. To Sam's two black hands, the light must have been too dim.
　　I swam close to them again. At this time, the English teacher and Sam seemed to notice that I was coming. The English teacher looked like he struggled for a while and then stopped moving.
　　"Teacher, Sam." I came to a stop about two meters away from them. Sun Xiaoxiao looked at me with a smile. Although the light was dim at this time, I could see that Sun Xiaoxiao's face was red and her eyes were red. Looked at me like water.
　　The English teacher at this time was too beautiful and touching, but why couldn’t I see Sam’s hand even though I was so close to them?
　　"Zihan, I am teaching the teacher how to swim. Hehe, she is so stupid. She usually teaches us so well, but now she is so stupid, right, teacher." Sam continued to stick behind the English teacher, and his body seemed to be shaking slightly. Because I saw the water in the swimming pool next to them rising and falling.
　　"Ah...yes..." The English teacher slowly raised her hand, looking like she couldn't swim at all. How did she swim in just now?
　　"Zihan, come here, the English teacher needs your help." Sam grinned and said to me.
　　"Ah...that...Zihan, no need..." After Sam said that, the English teacher said to me nervously, looking at me with such charming eyes that he almost felt like water was flowing out.
　　"How can you not need help? Teacher, there is too much milk in your two breasts, which seriously affects your balance. Ask Zihan to help you express the milk and drain it out." Sam said , I saw that the water circle under the English teacher was getting bigger and bigger, spreading out faster and faster.
　　The English teacher lowered his head and raised his head to look at me. His two white and tender arms were weakly sliding slowly on the water.
　　"Ah...um...that...um...Zihan...can you help...teacher?"
　　After a while, just five or six seconds, Sun Xiaoxiao looked up at me again, and her eyes had become blurry and moist. Hong's little mouth opened slightly, and her open hands slid into fists, looking like she was enduring something extremely.
　　"Uh..." I was at a loss. Are you asking me to express milk? I swallowed. I wanted to give it a try, but after all, she was my English teacher. Would touching her breasts be immoral and against human ethics?
　　"Sam, didn't you hear what the teacher said? Are you stupid?" Sam looked at me angrily and said, his eyes were like telling me, come and help quickly.
　　"Okay." I had no choice but to swim closer to them.
　　At this time, I finally saw where Sam's hand was. His dark hand stretched from Sun Xiaoxiao's snow-white back into his chest. It was covered by the black swimsuit on Sun Xiaoxiao's chest. Only then did I look. Not within Sam's hands.
