Primordial 'Dual Cultivator' Dragon With System

*Slurp... Slurp...*

Ling Xiya seemed to really enjoy playing with Ling Yun's dick; sometimes she licked the shaft of his dick, sometimes she just sucked on the head of his dick and licked the small slit above it, and her hands also didn't stop gently squeezing his testicles.

Ling Yun continued to gently rub her head as he enjoyed Ling Xiya's service on his dick. 'I wonder how Mingyue taught her about sex. She's still too young, yet her skills are already on par with mom and the other grown women.'

*Slurp... Slurp...*

Ling Xiya had put his dick deep enough into her mouth, and she was sucking on it hard while her tongue kept dancing on the head of his dick.

Before long, Ling Xiya looked up at him. 'Brother, I can't wait to swallow your semen, so release it in my mouth.'

The voice transmission from Ling Xiya startled Ling Yun. He smiled wryly and used his technique to release his semen into her mouth.

Ling Xiya's eyes lit up as soon as she felt Ling Yun's semen in her mouth, and she swiftly swallowed every single drop of semen that he had kept releasing.

After she finished swallowing it all, Ling Xiya immediately climbed onto Ling Yun's lap and cleaned her mouth with qi. She kissed his lips briefly and inserted his cock into her already wet pussy, and she winced in pain.

Even though Ling Xiya is no longer a virgin and her pussy is too wet, Ling Yun's dick is still too big for her pussy, especially since this is the second time she has had sex with him.

Ling Xiya then tightly hugged Ling Yun's body and spoke quietly. "Brother, your dick is truly big, and it made my pussy full, but I like it so much."

Ling Yun laughed at that and rubbed Ling Xiya's smooth back, and he asked curiously. "Tell me, where did you learn about sex? Was it Mingyue who taught you?"

Ling Xiya giggled, making Ling Yun even more curious, then she explained it to him. "At first, I peeked at my father and mother by accident, and then it was my mother who taught me. She taught me so that I could satisfy the man who would become my husband in the future, but I also often watch adult movies on the internet."

Ling Yun's mouth fell open at her confession; he thought that Ling Xiao and Yun Mingyue were really crazy to let their daughter watch adult movies, especially since Ling Xiya was still too young.

Ling Xiya chuckled at Ling Yun's reaction, then she kissed his lips and started moving her hips. "Mhn~"

Ling Yun sighed inwardly and kissed her back, then he started pumping Ling Xiya's petite body. Compared to his other women, she was indeed the smallest and slimmest, and her breasts were around a B cup.

"Mhn~" Every time Ling Yun's dick moved, it rubbed every side of her pussy and even up to her clitoris, making Ling Xiya immersed in sexual pleasure. "Mhn~"

'Shit! Her pussy is clamping my dick really hard.' Ling Yun enjoyed it a lot. In his opinion, the pleasure of having sex with Ling Xiya was really different. 'Could it be because her body is too small? That's why her pussy got so tight.'

Ling Yun then turned Ling Xiya with her back to him. With one hand, he gently rubbed and squeezed her breasts and nipples in turn, while his other hand rubbed her pussy, and he didn't forget to lick her neck as he continued to speed up the movement of his dick.

"Ahh~ I can't take it anymore, brother. I'm cumming~ Ahh~" Getting stimulated in all her sensitive points at the same time, coupled with the intense thrusting of Ling Yun's dick in her pussy, made Ling Xiya reach her orgasm very quickly.

[You obtained 800 Yin Qi from the individual named Ling Xiya.]

'Oh? The amount of her Yin Qi has increased now?' Ling Yun was surprised to see the notification, because he had previously only obtained 500 Yin Qi from Ling Xiya.

Ling Xi immediately explained it to him. "Indeed, that is how powerful the natural yin body is! Although her cultivation is still in the Middle Great Spirit Master Realm, her Yin Qi is far stronger than your other women. If her cultivation continues to improve, her Yin Qi will also continue to get stronger."

'I see.' Ling Yun nodded in understanding; he then pulled Ling Xiya, lying on her back on top of his body, and he fucked her even faster as he continued to stimulate her sensitive parts.

"Ahn~ Having sex with you is really satisfying, brother!" Even though she had just reached her orgasm, all of Ling Yun's actions made Ling Xiya's lust not decrease at all but instead rise even higher. "Ahh~ Fuck me faster, brother!"

Feeling unable to move any faster, Ling Yun changed their position. He made Ling Xiya crawl on all fours and directly fucked her from behind.

*Pa... Pa...*

With doggy style, Ling Yun was able to move more freely to fuck his half-sister, and he continued to fuck Ling Xiya faster and harder.

"Mhn~ Your dick went so deep into my pussy, brother!" Ling Xiya moaned louder as she felt the pleasure of Ling Yun's dick repeatedly touching her womb.

Ling Yun then bent down and squeezed Ling Xiya's breasts as he whispered. "Do you like my dick, little imp?"

"Ahh~ Yes~ I like it so much Ahh~ Your dick is the best~" Ling Xiya's moans grew louder and louder as Ling Yun fucked her even faster.

'I can't hold on anymore.' Ling Yun inwardly muttered, then thrust his dick very deeply, and he released his semen directly into Ling Xiya's womb.

At the same time, Ling Xiya's body also convulsed violently, and she moaned so loud in pleasure. "Ahh~ I'm cumming again!"

[You obtained 800 Yin Qi from the individual named Ling Xiya.]

"Let's continue, brother! I'm still not satisfied to have sex with you."

'This little imp! Why is she being so lustful now?' Ling Yun laid Ling Xiya on her side and lifted up one leg, and he fucked her from behind.

Ling Xi inwardly laughed at them, and she purposely didn't tell Ling Yun that she gave some of her essence to Ling Xiya, which made her extremely lustful. 'Haha! You should be thanking me! The more often you dual cultivate with her, the faster your cultivation will increase!'

*Pa... Pa...*

"Mhn~ you're too strong, brother! Even though you've just orgasmed, your dick is still hard inside my pussy." Not only had she become very lustful, but Ling Xiya had also become increasingly strong in sex, and she still didn't want to stop having sex with him.

Ling Xiya was like a woman who was addicted to the pleasure that Ling Yun gave her; she really wanted to feel it again and again, and she also didn't care even if her body was exhausted.

[You obtained 800 Yin Qi from the individual named Ling Xiya.]

A few minutes later, Ling Xiya reached her third orgasm, and Ling Yun also released his semen again in her womb, but both of them still didn't want to stop having sex.

"More~ I want more~ Fuck me more~ Big Brother." Ling Xiya begged him.

Ling Yun smiled bitterly at her request, he never expected that Ling Xiya would be addicted to having sex with him now. He then made his half-sister lie down on her stomach and spread her legs apart, and he immediately fucked her again.

"Ahh~ This feels so great!" Ling Xiya continued to moan, and her hands gripped the bed sheets, enjoying the pleasures of every thrust of her half-brother's dick in her pussy.

*Pa... Pa...*

Ling Yun himself was more and more eager to fuck her, especially when he heard her erotic moans, and it fueled his lust.

In the living room, Yi Mingxia and the others kept laughing while listening to Ling Xiya's pleasurable moans. At first, they were shocked to hear her moaning so loud, especially since she was the youngest of them, but she was actually the most lewd and erotic.

On the other hand, Yun Mingyue couldn't help but sigh when she listened to her daughter moan like that; it also ignited her lust, but she didn't want to disturb them while they were having fun.

"Ahn~ I'm cumming again, brother!" This time, Ling Xiya's body jerked more vigorously than her previous three orgasms.

"Me too." Once again, Ling Yun filled her half-sister's womb with his semen.

[You obtained 800 Yin Qi from the individual named Ling Xiya.]

After she reached her fourth orgasm, Ling Xiya finally felt exhausted, and she panted heavily under Ling Yun's body.

Ling Yun then pulled his dick out of her pussy and laid down beside Ling Xiya, and he hugged her from behind as his hand fondled her breast. "Are you satisfied now?"

"Not yet." Ling Xiya replied as she tried to catch her breath. "However, my body feels so tired right now, so I want to rest before we continue."

Suddenly, they felt a small shockwave, and they heard Zhao Yao's angry cry. "Hey! You guys are having fun without waiting for me!"
