Adultery My Mom & the exchange student

[Penetration]

Well, Sam was actually touching the English teacher's breasts. Although it felt a bit strange, a full of excitement flooded into his brain.
　　"Hmm...hum..."
　　Being close to the English teacher, I even heard her faint moan.
　　"Zihan, each of us will help the teacher express one breast." Sam said, taking out his left hand from Sun Xiaoxiao's plump left breast, while his right hand was still holding the right breast.
　　"...this" I really don't know how to do it.
　　"Zihan...help...help...teacher...uh huh...quickly...Zi...han...uh huh..."
　　Just when I was hesitating, Sun Xiaoxiao looked at me with blurred eyes, her mouth slightly open, and when I got closer, I realized that the pink tongue in her mouth was also slightly sticking out.
　　She's actually begging me to help her? I thought it was incredible, and looked at Sam. At this time, Sam had buried his face in the back of Sun Xiaoxiao's snow-white neck, and the sound of licking and kissing kept coming.
　　"Um...Sam...uh huh...slow...no...go to...hum...um..." the
　　English teacher moaned again and was talking nonsense.
　　"Zihan, why don't you help the teacher?" Sam looked at me from behind the English teacher, looking at me helplessly.
　　"Okay."
　　Seeing Sun Xiaoxiao's moving look, I suddenly became bolder. I stretched out my hand and slowly slid it in through the gap in her swimsuit under her arms.
　　"Ah..." As I held Sun Xiaoxiao's hot and moist breasts in the water, she moaned happily and comfortably.
　　The soft touch came from the palm of my hand, the warm breasts and the slightly cool feeling of the swimming pool water. I felt that the cock under me suddenly became erect.
　　Sun Xiaoxiao's nipples are so big, they feel much bigger than Li Xiaojun's. This must be the reason why the baby drinks her milk.
　　"Ah... be gentle... hmm..."
　　I pinched the big raised nipples hard, and the English teacher actually let out a much louder moan from his small mouth. This made me startled and I looked around. Fortunately, there was no one in the innermost part of the pool except us, most of them were swimming in front of the pool.
　　The strange thing is that as I pinched it, I saw a milky white liquid on the clear and transparent water that looked like milk dripping on the water and spread out. Could this be human milk?
　　I was so excited by this thought that I continued to squeeze Sun Xiaoxiao's breasts vigorously.
　　"Ah... Zihan... don't... huh... you're trying too hard... be gentle... be gentle... help the teacher... express the milk... um..." The
　　English teacher's white arm stretched out to me and touched my chest.
　　Her hands are so soft, isn't it, is she touching me?
　　This unprecedented stimulation made my cock so hard that it was about to explode. I also rubbed her plump left breast with lots of milk.
　　As for the right breast, in the black swimsuit, I could see Sam constantly deforming and holding the big breast, and white liquid kept spreading on the water.
　　"Ah...um...don't...ah ha hum..."
　　Just as I was looking at the milky white milk floating on the water, the English teacher suddenly said "no."
　　What don't you want? I looked at the English teacher in confusion, but at this moment I saw her eyes closed, her whole body lying back in Sam's arms, her red mouth open, her head tilted up and resting on Sam's right shoulder.
