The cock started to jump at the age of 13 (other adult novels)

When I knew that no one was at her house, I felt a little weird in my heart. Sitting at the desk, Xiaozhen was working hard on her homework, but I kept meowing at her. Xiaozhen was wearing a thin T-shirt and shorts, but her chest was bulging. The T-shirt must be very old, as the neckline looked loose and large.

"Pah..." Xiaozhen's pen accidentally fell to the ground, and she bent down to pick it up. Because I kept peeping at her, when her body moved downwards, the neckline became lower and lower, starting from her neck to her collarbone in front of her chest. Slowly, the neckline stretched the T-shirt to create a big hole. Following my line of sight, I saw Xiaozhen's snow-white chest skin, with two towering curves going down and a deep, dark groove in the middle. I greedily looked down quickly, wow..., two pink nipples were shaking at the highest peak of the curve. Who would have thought that at this minute, I could see Xiaozhen's full breasts through the loose neckline. I started to feel hot, and the strangest thing was that I felt very hot below the waist, and my balls and penis felt a little uncomfortable, so I ran out in a hurry.

"Where are you going?" Xiaozhen shouted.

"I'm going to pee," I replied.

When I got to the bathroom, I noticed that my shorts were bulging. I quickly pulled down the zipper, wow... ,how so?

————————————————————————

"Wow………"

In the bathroom of Xiaozhen's house, I saw for the first time my little cock that had become hard and enlarged in size. I was a little scared because I didn't know what was going on.

The most embarrassing thing is how I am going to meet Xiaozhen later, because my pants are bulging a little bit from the zipper area.

"I'm almost done, what are you still doing in there?" Xiaozhen shouted outside the bathroom, asking me to open the door. I ran to the seat in Xiaozhen's room and followed her in, saying that the math problem '2X+Y=aX+3Y/2' was very difficult... , pulling up a chair and sitting next to me.

You know, I was already restless at that time, and my swollen little cock could not hide in my shorts. In addition, Xiaozhen was shaking her legs, which kept sticking to the sides of my thighs. Her smooth pink skin scratched me, and I felt hotter and hotter, not just in my lower body.

Xiaozhen couldn't solve the math problem, so she stretched her arms behind her and stretched. At this time, I clearly saw that her T-shirt was stretched tightly, and her two nipples were exposed without retaining their shapes. Xiaozhen realized at this moment that I had been staring at her breasts for a long time.

"Wow, you're so lustful." Xiaozhen slapped my arm hard.

I was not paying attention and fell on my back. Xiaozhen hurriedly asked me why I was so weak and bent down from her chair to help me up. However, Xiaozhen failed to pull me up and was dragged down by me and fell on me.

In a hurry, we hurried to get up, "Wow, what's in your pants, it's hard." Xiaozhen grabbed my hard cock through my pants without hesitation.

My face turned pale and blue and I pushed her away harshly. Xiaozhen didn't understand what was going on yet. I stood up with my back to her and said, I want to go home.

I took my notebook and textbooks, walked out of Xiaozhen's house through the back door, and looked down at my pants. Oh my God, they were still hard and swollen, completely different from normal. Was God punishing me for secretly seeing Xiaozhen's nipples?

I walked through a small forest behind Xiaozhen's house. There were two warehouses built together. Maybe because of my enlarged penis, I walked a little slowly.

“Hmm… Hmm… Hmm…”

"You are so bad" "Hmm... Hmm..."

Before I reached the warehouse, I heard strange moans and sucking sounds. I was really curious, so I walked to the big tree in the corner of the warehouse and stood on a stone.

In the moonlight, I saw Xiaozhen's sister Coco and an unfamiliar boy, who should be a high school student and was wearing a uniform.

What I saw was that they were pressed tightly together, moaning with their eyes slightly closed. The high school student put one hand into Coco's shirt and kept rubbing it, and put the other hand into her skirt and pumped it. Coco's buttons had been almost all undone, and her breasts, which were being rubbed, had long been squeezed out of the light purple bra. The high school student's tongue licked around her nipples. Suddenly, he sucked her nipples up high with his lips, and as soon as he let go, he let the nipples bounce back gently. "Hmm... Hmm... Hmm..." Coco's moans were making people feel a little flustered.

I peeped greedily, trying to see what the high school student was doing with his other hand.

In fact, it was quite dark. I could only see the skirt being lifted up, revealing her snow-white thighs, shaking constantly. I could only vaguely see the hand moving in Coco's light purple panties. I wanted to see it clearly, so I took a step forward.

"Bang..." I accidentally stepped on a dead branch.

The two people behind the warehouse suddenly jumped up and looked in my direction. The high school student was more like a mouse stealing rice. He ran away in a blink of an eye, leaving Coco alone.

"Who? Dad?" Coco's voice trembled a little.

I was a little at a loss, and stepped down the stone step by step. Coco grabbed her clothes and walked forward. In the moonlight, I think we saw each other.

"Damn, kid, what are you doing here?" Coco grabbed my clothes and pulled me to the warehouse.

Coco is only two or three years older than me, but she always treats me like a child and never calls me by my name but calls me kid instead.

"Kid, why are you peeking here?" Coco cursed me in a low voice.

She hooked her arms around my neck, then suddenly pushed me away, paused for a moment, and looked down at my waist.

"Wow, when did you become an adult?" Coco noticed my bulging crotch and grabbed my cock without saying a word.

At this moment, my trembling heart suddenly erupted like a volcano.

I saw Coco's completely opened shirt, her tender white breasts squeezed above her bra that was not put on properly, her cherry-red nipples standing tall, and my palms and cheeks began to sweat again.

"If you don't tell anyone else, especially Xiaozhen, I will let you touch it." Coco said as she pulled down my zipper.

I didn't answer her. My hands, like possessed, restlessly caressing her breasts. "I want to lick your nipples. Can I?" I said.

"Hmm..." I looked up and saw her humming with her eyes closed. I thought that was the answer.

Looking at the nipple, which seemed a little hard and a little longer, I followed the example of the high school student and stuck out my tongue to fiddle with the small fleshy protrusion. Furthermore, I also learned to draw circles on the surrounding areola.

"Hmm... Hmm..." "Oh... kid, don't stop... Hmm..."

The entire nipple was covered with my saliva and was a little wet. My hands were still grabbing both breasts, squeezing them hard. It was like a boneless lump of meat. No, it was more tempting than that. It was soft and elastic, with smooth skin.

Suddenly, a gust of wind blew and I felt a chill in my lower body. I looked down and found that Coco had pulled my shorts down to my feet without me noticing. One of her hands was sliding up and down on my cock, which was as big as a penis, and she was gently scratching my glans with her index finger.

At this time, Coco also looked down and said, "Wow, your dick is so hard even though it doesn't have any hair yet." She seemed to be very experienced in discovering strange things.

"…I got hard for the first time today." I said blushing.

Coco covered her mouth with her hands and laughed so hard that her breasts bounced up and down.

"Little boy, I'll give you even more excitement..." Coco's eyes revealed a kind of lustful charm that I had never seen before.

Coco squatted down and buried her head between my legs. I couldn't see clearly what she was doing in the dark, but my whole dick just felt wet and hot, and was tightly surrounded. It seemed like there was a soft and slippery object wriggling on the skin of my dick. When I looked closely, wow, Coco was holding my dick and almost stuffed the whole thing into her mouth.

Then, she sucked the skin of my scrotum with her lips, bit it gently, and with a whoosh, she wrapped one of my balls in her mouth. At this time, I could no longer describe the feeling in my lower body. It was completely tingling and numb, and I almost melted.

The night wind gently slapped the leaves beside the warehouse, swaying with a rustling sound. The moonlight shines through the gaps in the leaves and falls on Coco's snow-white skin. I swallowed and greedily licked that skin with my eyes.

Coco stood up and told me in a slightly commanding tone to put my hand under her skirt. As soon as my hand reached inside her skirt, I touched her cotton panties. I didn't know what to do with my whole palm, so I had to cover her entire vagina and slowly fiddle with it. Not long after, I felt some liquid seeping out from there, and it seeped through the underwear and covered my palm.

At this moment, I could no longer suppress my curiosity and inexplicable excitement. I raised my sticky and wet palm and slowly put it into her panties, only to feel the tip of my finger touching the thick fine hair. I tried to pass through the thick hair like a pile of grass, and a slippery mucus and a warm feeling came from my fingertips. I was secretly surprised, wow..., how could there be a tender and soft gap here? I let a finger quietly explore inside, "Puff... Puff..." My fingers stirred the sticky liquid in the gap. In the quiet night, the sound was clearly transmitted to my ears. Looking down, my little cock that grew overnight, no, now it is a huge cock, which has swelled a little more than before, with a full glans, rosy penis, and many blue veins emerging, standing tall in Coco's hand.

Looking up, Coco's eyes were slightly closed and her red lips were slightly parted. I don't know why I felt that she was so beautiful at that moment and I wanted to kiss her. Of course, my mouth never stopped and kept kissing her chest and cheeks.

"Come on, little boy..., fuck me..." Coco held my dick and moved it close to her lower body.

I was stunned.

"I, I, I don't know..." I said at a loss.

Coco stopped her hand movements and quickly took off her light purple cotton panties from under her skirt and stuffed them in her pocket.

She hooked one hand around my neck, put her left foot on the stone vat next to her, and used the other hand to push my dick into her lower body. When my glans touched the soft wall, a electric shock feeling spread from my lower body to the top of my head.

"Wow, this is amazing..." I thought to myself.

As the cock slowly sank forward, a very comfortable temperature was gently embracing it, and stopped deep under her thick black hair, becoming wetter and hotter, and the cock felt numb and about to melt.

"Um...well..., little boy..., fuck me quickly." Coco urged.

I really didn't know what to do at that time. Coco grabbed my butt and pushed me towards her lower body. Ah, it was too tight, too wet and hot. I pulled my dick out, but she pulled my butt again and pushed me forward. Between the in and out, I suddenly felt it was a bit fun. Without waiting for her to push, I hugged her upper body with my hands, and my lower body moved in and out automatically.

Maybe it was a boy's instinct, the movement of my hips became smoother and smoother, and with every thrust, I could always feel the glans rubbing in the tender flesh, giving me an indescribable pleasure that was getting higher and higher, "Hmm... Hmm..." Coco no longer made any moaning sounds, but only made some panting sounds.

I don't know how long it was, but more and more sticky fluid flowed out of Coco's lower body. Every time I pulled out my dick, a lot of white threads came out. The faster I thrust, the more intense her moans and pant became. Suddenly, my dick twitched, and the glans in the slit seemed to be pinched. From deep inside, a hot stream like steam from boiling water rushed towards the glans. "Hmm. Hmm. Oh... Oh..." Coco moaned a little loudly. At this moment, a hot stream also gushed out from the middle of my glans, and I couldn't help but shoot out into Coco's body, ah... , my legs went limp helplessly.

After calming down, Coco pushed me away and adjusted her clothes. She said to me, "Do you like my pussy?" "It feels so good!" "Remember, don't tell anyone else about what happened tonight." After saying that, Coco turned and walked away.

Looking at her figure, I looked down at my own lower body which was still drooping and soft, returning to the familiar length before, but it felt a little worn.

For some reason, I didn't talk to Xiaozhen in the next few days, and Xiaozhen and her friends were busy with the cheerleading competition. After school, even if I had time, I didn't go to her house to find her. Maybe I felt guilty and kept thinking that what happened with her sister would be written on my face and would be discovered.

That Sunday morning, the weather was very good, and I hurried to Xiaozhen's house to find her. We went to play in the stream on the mountain. She happily agreed and wore a short, thin T-shirt and a pair of semi-cotton pink hot pants. Then we each rode our bicycles up the mountain.

————————————————————————

We rode to the roadside on the mountainside, then passed through the woods and walked down the slope, and arrived at the stream upstream.

In fact, Xiaozhen and I both felt a little tired. She was also panting with sweat all over her body. Looking at Xiaozhen's T-shirt, it was already mostly soaked with sweat. I could vaguely see the white bra with small floral patterns inside. Maybe after the experience of messing around with Coco, I became bolder and stared at her.

Xiaozhen didn't notice it. She lowered her head and wiped the sweat from the inside of her thighs with a handkerchief, asking, "Aren't you going to tell me something?"

"I like you" I said it without thinking, and even I was shocked.

"Oh..." Xiaozhen still kept her head down. After a while, she said, "I like you too."

The sun was getting a little hot, and it made Xiaozhen's face even redder. I took her hand and said, "Let's walk to a rock under a tree." I then put my left hand around her waist and we sat down together.

"If you like me, then you like me. Why did you act so weird a while ago?" Xiaozhen suddenly turned her head to face me, almost nose to nose.

"Well..., because..." I didn't know what to say.

I suddenly hooked her head up with my right hand, and my lips quickly pressed against her lips... I stopped and waited for Xiaozhen's reaction, but she did not resist. I began to gently suck on those two small but somewhat plump lips, "啾...啾..." I sucked more and more greedily, and at the same time felt the tender lips. From her slightly opened mouth, I felt some warm air, and my tongue unconsciously stretched into her mouth. I learned that from Coco. Xiaozhen also moved her lips slightly, and held my tongue in her mouth, "啾..." When my tongue touched her soft tongue, my cheeks began to feel her face getting hot.

At this time, I was already lying tightly on her.

"What hard object did you put in your pocket again?" Xiaozhen slowly pushed me away and said.

I turned around, sat up and said, "This is what you touched last time."

"What is that?" Xiaozhen asked me, tilting her head.

"Okay, I'll let you know but don't scare you!" I warned her.

"I'm very bold." Xiaozhen said, pulling my arm.

I pulled her little hand and held my hard cock through my pants.

"It's so hard and big!" Xiaozhen said as she explored the curve of the cock.

I said, "This is my little cock."

"Liar?" Xiao Zhen continued to caress me, she didn't know that her actions were almost making me explode.

"If you don't believe me, just reach in and touch it!" I said.

"You are so shameless..." Xiaozhen paused and said, "Is it really okay..."

I opened the waistband of his pants with one hand and took her little hand and put it in with the other hand.

As soon as Xiaozhen reached in, she grabbed my hardened dick, "It's so hot and burning... so hard and big... so..." Xiaozhen said excitedly and in surprise.

My dick lay in that soft little hand, feeling soft and light like tofu. Being held by Xiaozhen, I think it had reached its limit. I suddenly wanted to strip her clothes off and do with her the same thing I did with Coco.

"Xiaozhen, I also want to touch your breasts, and that place down there..." I said excitedly.

Xiaozhen pulled her hand back and said, "No."

I stood up and pulled my shorts all the way down. My big, hard, red, thick cock popped out. I said, "What about my little cock?"

Xiaozhen slowly lowered her head, kissed my purple-red glans with her lips, and then smiled at me faintly.

For the love of Xiaozhen. To give her the respect she wanted, I thought, I'll just go home and jerk off.

Although I didn't see Xiaozhen's naked body, after that day it seemed that we became a real couple, especially since I often received love letters from her.

After that, Coco threatened me deliberately, saying that she would stop me from pursuing Xiaozhen, and even told Xiaozhen that I had done that with her. So, I had to do it again, and we did it several times behind the warehouse. And each time, we became more and more arrogant, "Hmm... Hmm... Hmm..." She liked to hear the slapping sound of me pushing hard into her pussy, "Harder..., harder..."

She panted and ordered me at the same time. The drier her pussy became, the more juice came out, making my whole dick wet. In fact, I really liked that slutty little pussy and that swinging ass.

I really care about Xiaozhen's feelings.

————————————————————————

About a week after that Sunday, one evening, Coco asked me to wait for her behind the warehouse again, saying that she had something to talk to me about.

Coco was wearing a camisole and shorts, sitting on an overturned stone vat. It looked like she wasn't wearing a bra, and her two nipples appeared as two small black protrusions on her camisole.

"I can help you, but now you have to make me happy for once." Coco said, putting her arms around my waist.

"......" I was in a daze and didn't say anything.

"Come on, I was masturbating in the room just now and it made me so excited. I want your cute big cock." Coco had already put her hand into my shorts and was exploring.

"…………" I was still thinking about how to explain everything to Xiaozhen.

Wow..., Coco pulled my hand and put it under her panties. It was already flooded with liquid. The whole vagina was wet and slippery. The vaginal fluid had already soaked most of her panties.

In fact, there is only Xiaozhen in my heart. What happened with Xiaoru or Coco happened inexplicably.

But a dick is a dick, and it doesn't seem to care much about my emotional world. In Coco's little hands, I rubbed and stroked it, and even at this time when I was in a bad mood, it was still made as hard as steel, erected high, with an elevation angle of 60 degrees, pointing to Coco's triangle area.

"Oh... my slutty big cock is getting hard again."

Coco climbed down the stone vat, took off her shorts and briefs, turned around and lay down beside the stone vat. She grabbed my cock and stuffed it into her wet pussy. "Ah...oh..." Coco started moaning as soon as the cock was completely inside her pussy. I really don't know how she masturbated in her room.

I grabbed both sides of her slender waist and rocked her back to meet the thrust of my cock, bang, bang, bang, after a hundred rounds in and out, the vaginal fluid flowed all over the cock, and between the thrusts, white filaments and foam were pulled out.

Just going in and out, in and out, slowly, the tip of the glans felt her vagina was extremely hot, "Oh..." It was my turn to moan, and the hot semen shot into the depths of her vagina.

After finishing the job, Coco kissed me and said that she liked me quite a bit and would help me put in a good word with Xiaozhen.

Sincerely thank the host for his hard work and selfless sharing
