Adultery My Mom & the exchange student

[Penetration]

　There seemed to be two panting breaths in the bathroom, and when I usually took a shower, I rubbed the body wash on my body and then applied the body wash to the whole body. 
　　"Uh huh..." Then, a beautiful female moan sounded from inside the door right next to my ear. My eyes widened in horror, and I almost fell down against the bathroom door. 
　　This...this somewhat lewd moan that I tried to suppress is very familiar to me, but I am not sure whether it is my mother's voice, because my mother's usual speaking voice is either gentle and intellectual, making me feel warm and caring, or cold and ruthless. I felt like I was in an ice cave, and the moan in the bathroom made me feel uncontrollably and lustful from the bottom of my soul. 
　　"Pah...pah...pah!" 
　　"Uh-huh...ah..." 
　　The sound of "pah-pah" was a few decibels louder than before, and the woman's moans behind the door also increased a few degrees. 
　　"Pah! Pah! Pah!" 
　　"Ah...ah ha..." 
　　"Crash... um... uh huh..." The woman's endurance seemed to have reached its peak. It seemed that after opening her mouth and gasping for two breaths from her throat, I heard Inside the bathroom door, something slid against the door, and then the woman inside the door changed from gasping "Ahhhhh" to moaning "Uhhhhhh" covering her mouth. 
　　However, when the woman seemed to be unable to restrain herself and opened her mouth, I seemed to hear the same sound quality as my mother's usual scolding voice. 
　　I was already squatting under the door and opened my mouth nervously, taking a big breath of air. I also tried my best to control my slightly trembling body to prevent the people inside from hearing that someone was outside the door at this moment. 
　　"Pah...pah...pah...pah...pah!", "Huh...huh..." "Uh 
　　...uh huh. Hmm..." "Pah!" 
　　, "Bang!" 
　　"Ah...um...ummm...huh..."
　　"Huh...huh..." When I listened nervously to what was going on inside, I heard several slow "pah-pah" sounds, followed by frequent "pah-pah" sounds. Finally, there was another heavy "pop" sound, and the bathroom door was also knocked. Then the woman moaned "ah" louder than before. She seemed to realize that the sound was a bit loud and covered it up. Mouth. 
　　After two or three seconds, two more extremely restrained breathing sounds came from inside the door. 
　　"Mom, thank you for coming down and wiping my body." Although it couldn't be someone else, I was still lucky and hesitant to use these two breaths to identify whether the people inside were Sam and my mother. The sound of unclearly biting Chinese characters reached my ears directly from the bathroom door without leaving any room.
