My name is Wu Lingling, I am eighteen years old, and I am just in my third year of high school. One weekend, my parents took me to their friend’s house to play. Their friend’s son was named Nao Ye. He had a childish face. He was two years younger than me and was in the first year of high school. After lunch, the adults played cards together, and Naano and I played in the room.
The two of us played computer games for a while, and Naono suddenly said to me: “Sister, why do people have genders? What is the difference between men and women?”
“Didn’t you take physiology class?” I said.
“In physiology class, the teacher said it was too general, why don’t you tell me, sister.” Nao Ye shook my hand.
“Okay, okay, my sister told you.” I was shaken by Nao Ye, and said, “The biggest difference between women and men is the difference in sexual organs.”
“What kind of female sex organs are there, can my sister show me?” Naoye said.
“No, that’s my sister’s private parts, you can’t show them casually.” I don’t know what the little boy is thinking.
“Look at it, look at it.” Nao Ye shook my hand again.
“Okay, okay.” I was so annoyed by him, I stood up and took off my skirt and panties. Today I wore a pair of black seamless pantyhose under my panties. After taking off my panties, I was only wearing a short shirt and no black silk, and my pussy was clearly visible under the thin black silk.
Naono was a little excited. He observed the plump breasts and black silk on my shirt, and couldn’t help erecting his lower body.
I saw Naono’s reaction and said, “Hehe, it’s the first time I saw a girl’s private parts.”
Naono nodded and said, “I watch a lot of videos with footjobs, can my sister give me footjobs?” After finishing speaking, he walked to a chair in the room, took off his shoes, sat on the sponge cushion under the chair, and rested his head in the hollow of the chair.
I observed the chair, the chair surface was soft, there was a hollow in the middle, and there was soft cotton under the hollow. The chair surface is connected to the floor by a board, which is 60 degrees horizontal to the floor, and the top of the board is also soft. On the floor under the board, there is a layer of sponge mat.
Naano sat on the sponge cushion with his legs stretched out, his back resting on the board connecting the chair surface and the sponge cushion, his head resting on his back in the recess in the chair surface, his exposed face slightly higher than the chair surface.
“Sister, please sit on the chair,” Naono said.
“What kind of chair is this, why is it so strange?” I asked.
“This is the top spot, bought online.” He said.
I was curious, and sat on the chair, with my pussy on Naono’s face through a thin black thread.
“It’s so embarrassing to sit like this.” I thought, as my private parts were pressed against his mouth.
Naano took out his penis, took out a condom, and put it on.
I sit on the chair, take off my slippers, and use my black silk feet to clamp the penis up and down.
The black silky texture on the feet rubs the groove under the glans of the penis. This may be the first time Naano has encountered a woman’s foot massage, and he can’t help humming.
“Hehe, the reaction is very good.” As I said, I felt a warmth in my lower body. It turned out that Naano opened his mouth to cover my labia minora, and licked it with his tongue through the black silk.
“Well, why did you start to lick it?” I said, and the itching continued to come from the lower pussy.
“My sister’s black silk is soft and slippery to lick, and it tastes salty.” Nao Ye said while licking me.
“Brother, you are so naughty!” I said, with my toes bent, I quickly moved my penis between my fingers. After a while, Naono’s whole body became stiff, and white semen sprayed out from the center of the penis.
“Looks like it didn’t last long.” I stood up and left the chair.
Nao Ye also got up, threw the condom into the trash can, took off his coat, only wearing a pair of underwear, walked to the bed, touched the middle of the bed and opened a cover, there was a bed hole the size of a person inside. He got into the hole in the bed and lay down on his back with his hands and head exposed, and his head rested on the soft cotton behind the cover.
The bed hole is surrounded by soft cushions. His legs are flat and his back rests on the soft cushions at about forty-five degrees from the horizontal. Lying on his back in the bed hole feels very comfortable.
I looked at Naono in the bed hole and said, “What kind of bed is this?”
“This is the bed, sister, come to bed quickly, let me see clearly.” Naoye said.
I had no choice but to get on the bed. According to Naono’s intention, I moved my buttocks in front of him, and sat down with two big pillows behind my back. My legs were separated in an M shape, and my private parts were ten centimeters away from his face.
Nao Ye observed my private parts. Under the thin black silk, a bunch of pubic hair under the pubic mons was pressed flat, and the pink and tender labia minora were slightly separated on both sides, revealing the attractive pink tender flesh inside. The black thread on the labia minora adhered to his saliva, making the stockings more translucent. the
Seeing Naoye staring at his private parts, I was a little shy and said, “Now my sister will give you a physiology class.”
“Can…can you part that slit so I can see it clearly?” Naono asked, swallowing his saliva.
“Don’t worry, brother Naano. First of all, let me tell you that the black seamless pantyhose on my sister’s legs is what women like to wear. You can touch it with your hands and feel its texture.”
Naoye touched the black silk on my thigh with both hands, and said, “It feels a little matte, smooth, and really comfortable.”
“Okay, let’s get to the point. In front of you is the female sexual organ, which is called the vulva, and below is the anus, which is the same as that of a male.”
Nao Ye opened my butt through the stockings with both hands, and said, “Hehe, it feels amazing.”
“Touch your sister’s anus with your left middle finger and feel it.”
Naano touched my anus with his middle finger, and felt the soft wrinkled wall of the anus through the stockings. He stretched in a little harder, but when he touched a circle of tightly closed muscles, he was blocked by the stockings and couldn’t get in.
Naono’s middle finger pressed that circle of muscles, which was very sensitive and kept contracting.I said, “That’s the anal sphincter, which controls bowel movements.”
Nao Ye
