"Sit here and show your back towards me

", Zhan Chen spoke after both Su'er and Ling'er stood up. A confused look appeared in the eyes of both of the girls but they still followed after the instruction of Zhan Chen. Ling'er sat on his right thigh while Su'er occupied his left thigh. Their pretty backs faced towards Zhan Chen's little brother.

Zhan Chen controlled the impulse of his little brother and planted a kiss on Su'er's pretty neck. He stretched his left hand and placed it on Su'er's sacred cave. He inserted a finger inside Su'er's cave and started do a back and forth movement with his finger. He did the same with Ling'er and inserted a finger inside her sacred cave.

'Ahhhhh~'

'Mmmmm~', both Ling'er and Su'er started to moan as Zhan Chen continued to please both Ling'er and Su'er with his finger.

He planted kiss on Ling'er's neck and licked her pretty ear lobe. Ling'er body heated up quickly by the actions that Zhan Chen was doing with her..

Su'er' and Ling'er's sacred caves moistened up quickly by the action of Zhan Chen.

"It seems like both of you girls are ready to go again

", Zhan Chen spoke with a smile on his face.

"Who is going first?

", Zhan Chen asked both Su'er and Ling'er. Both Su'er and Ling'er blushed and quickly exchanged glances with each other.

"Young master, let sister Su'er be the first

", Ling'er spoke.

"Does not matter. Your turn will come up soon

", Zhan Chen spoke to Ling'er and rubbed his finger on Ling'er's sacred cave.

"Ahhhhh~

", Ling'er moaned lovingly after Zhan Chen rubbed her little sister again. Zhan Chen planted a kiss on her pretty neck and pushed her body gently with his hand.

Ling'er understood and made way for Su'er. Zhan Chen planted a kiss on Su'er's neck and lifted up her body with both of his hands. Then he pointed his dragon towards her little sister and placed her on top of his dragon.

His dragon penetrated deep inside Su'er's cave. Su'er moaned as the penetration was too intense for her. Zhan Chen was still holding her by her waist as he helped her body in moving up and down.

Ling'er who was watching the scene from nearby blushed as she had never seen her young master doing such intense things with them. First that bull like thing with miss Shu and now this with her sister Su'er. Ling'er felt amazed by the talent of her young master.

Zhan Chen smiled at Ling'er after noticing her charming expression on him. Ling'er blushed again as she looked forward to save herself from embarassment.

'Ahhhhh~

Ahhhhh~

Ahhhhhhh~', Su'er moaned as her body was being penetrated in air. Zhan Chen was still in the sitting position and moving her body in air. His hand was holding her body and he was dropping her up and down on his dragon.

With his each downward movement, his dragon was penetrating deep inside Su'er's cave.

Su'er face was towards Ling'er and her back was still facing Zhan Chen. Zhan Chen was holding her body in the air and dropping it on his dragon as he wished.

Ahhhh~

Mmmmm~

Ahhhhhhh~', Su'er's mind grew blank after a minute. There was only pleasure and ecstasy coming from her nether region.

Zhan Chen didn't stop thrusting his dragon inside her and her little sister couldn't handle his dragon after few minutes of intense thrusting.

"Young master, it is coming~

", Su'er moaned as her yin water built up inside her cave. With another few thursts of Zhan Chen, she released her yin water in a bursting wave.

Zhan Chen pulled her body close to his chest and let her rest for a minute in his embrace. His dragon was still standing proudly even after such intense exercise between it and Su'er.

Zhan Chen felt a greedy look on his little brother. He looked over and saw Su'er was watching his little brother without blinking her pretty eyes.

"Ling'er

", Zhan Chen laughed at the lovely girl who was looking at his mighty dragon.

"Young master, why it is growing everyday?

", Ling'er blinked her eyes and asked.

Zhan Chen chuckled after hearing the curious tone of Ling'er. He knew she was saying the truth as his dragon was increasing in size after being drenched by the yin water of so many girls.

"Come over first. Put it inside your mouth and I will tell you why it is

", Zhan Chen smiled towards Ling'er.

Ling'er nodded her head and knelt down infront of him. Then she struck out her tongue and take a lick of his little brother.

She licked his dragon almost over a minute. Her curious eyes were falling upon Zhan Chen from time to time.

"Ok, stop looking at me like that. Let me show you a thing. So that, you can understand

", Zhan Chen chuckled.

He freed his dragon from Ling'er's hand and concentrated his focus on his little brother. With a will of his mind, his dragon trembled and veins started to bulge on its body. Then as if someone was peaking a fight with his dragon, it started to increase in size and length.

Ling'er's mouth became wide open after she saw what was happening infront of his eyes. Zhan Chen's dragon was now much longer compared to its previous self. It's girth had also increased as it was appearing mightier compared to before.

Ling'er gulped down her saliva audibly as such an inconceivable thing happened infront of her eyes. Zhan Chen felt pleased after seeing her cute appearance.

"I can't control my size proficiently now. But it can be done with few practices. In future, I can make it double in size by controlling that region of my body

", Zhan Chen explained to Ling'er.

He also found it inconceivable when he read about this technique. But practicing Myriad transformation technique along with Celestial Yin Yang sutra could make this impossible looking thing possible. Zhan Chen commended evil emperor's skill after reading such a technique. It is said that at his peak, evil emperor had even managed to dual cultivate with a giant princess.

With myriad transformation technique, one could control his body size and shape and when added with such dragon transformation skill, it could enable a person to dual cultivate with almost every girls in this world.

"Ling'er, why are you dazing out? take it in your mouth

", Zhan Chen smiled towards Ling'er. Ling'er nodded her head and took in his enraged dragon.

"Slurp! Slurp! Slurp

", she moved her head back and forth and started to please the mighty dragon of Zhan Chen.

"Body transformation technique is not that simple as I have thought. After fifth level it crossed the level of mortal bound and became a technique of those legendary existences

", Zhan Chen thought to himself.

He noticed Su'er's gaze on him and she also had a dazed appearance after seeing his increased size. She had already sat up from her lying position and looking at his mighty dragon.

"Su'er, do you want to join Ling'er?

", Zhan Chen smiled towards Su'er. Su'er blushed but still nodded her head. There were anticipation visible in her pretty looking eyes.

"Slurp, slurp, slurp

", Ling'er continued to move her head back and forth as she took in the mighty dragon of Zhan Chen. Her mouth looked like bloating as she was taking in the enraged dragon of Zhan Chen.

Su'er knelt beside her and Ling'er pushed Zhan Chen's mighty dragon into her mouth. Zhan Chen ft a wave of pleasure as both of the girls continued to please him with their mouths.

"Ling'er, do you want to cultivate with it?

", Zhan Chen pointed at his little brother. He was ready to decrease his size if Ling'er found the size of his dragon uncomfortable. But contrary to his thinking, Ling'er nodded her head with anticipation.

She had some hesitation but she still want to took in the dragon of Zhan Chen. Zhan Chen's evil fire surged after seeing her expression.

"Su'er, wait a bit. Let Ling'er cultivate with me

", Zhan Chen spoke to Su'er. He turned over Ling'er and picked up by her waist. Then like Su'er, he make her sit on top of his dragon.

He slowly released her slim body and Zhan Chen's dragon penetrated inside the sacred cave of Ling'er.

"Ahhhhh~ So deep

", Ling'er cried out as her eyes moistened. It felt like if her little sister was going to burst apart.

"You are still not ready for this size

", Zhan Chen murmured and reduced his size by a finger. His girth also decreased but it was still greater than his previous size.

Ahhhhhh~

Ahhhhhh~

Ahhhhhhhh~', Ling'er moaned as Zhan Chen continued to drop her body on his mighty dragon.

"Young master, please stop. It is too deep

", Ling'er cried out after half an minute.

"Relax

", Zhan Chen reverted his dragon to its previous shape after she heard Ling'er's voice. He was just experimenting. So, he wouldn't let his girls suffer due to it. Su'er and Ling'er were still tender. They could slowly adapt to his original size.

Ling'er felt disappointed but she knew she couldn't take on that size. She adjusted herself to the recent size of Zhan Chen as her mind again clouded by pleasure.

Ahhhhh~

Ahhhhhh~

Ahhhhhhh~', Ling'er moaned and released her yin water within few minutes. The previous experience was too intense for her little sister. She could last only half of her previous time.

"Su'er take it inside your mouth. I will release my yang essence inside you

", Zhan Chen spoke and freed his dragon from Ling'er's cave.
