Chapter 1

　　It was in late October, and the weather was still hot.
That afternoon, Li Bing came back from school. He just put down his school bag, took off his short-sleeved shirt, and was about to take off his pants when he suddenly heard a loud noise inside his mom's room.
Out of curiosity, he walked to his mom's door. Through the unclosed doorway, he saw that his mom was changing her clothes and was naked.
Because he was standing beside the bed, Li Bing could only see the side of his mom. On the opposite side was a dresser, and the mirror on the dresser was neither big nor small.
Through the reflection of the mirror, Li Bing took in his mom's graceful torso.
He only saw that his mother's body curve was so concave and convex, her buttocks were erect and plump, and her huge snowy peaks showed no sign of sagging, and they were white and tender.
In an instant, Li Bing felt as if his body was electrocuted, and almost spurted out nosebleeds. The guy below, was also stimulated, and raised his tent.
He is eighteen years old this year, it is the age of curiosity about women. And although mom has already given birth to a child, the body is still slim, the convex convex, the warped.
When you walk outside, there are people who believe that she is Li Bing's sister.
Besides, Li Bing's deskmate lent Li Bing a small yellow book.

The woman in the book is not as good as his mom, but he is afraid of being found out by his mom.
He was afraid that his mom would find him, and immediately ran to the table again, pretending to do his homework. But at this moment, his mind was full of his mom's snowy peaks, ass, and the slender curves, and he didn't have the heart to focus on the topic at all.
Then he remembered the self-pleasuring moves taught in the book earlier.
It was said that it would be very comfortable if he did it, and at this moment, he was already hard down there because of the stimulation. So, the clueless Li Bing directly held it in his hand and started to lasso it.
