It was pretty clear that dragon and phoenix made from this strange yang and yin energy were trying approach each other in turn trying to make Liu Zheng and Su Yan get closer to each other respectively.
Even though Liu Zheng's cultivation was only two minor realms higher than Su Yan, his qi reserves and foundation were inhumane so Su Yan was having a much harder time than him and after some time she almost couldn't bear it.
Liu Zheng seeing this instantly hugged Su Yan trying to help balance her qi and make her feel better.
"Forgive me! I don't think I can bear it any longer." He said but what he actually meant was that he couldn't watch her suffer any longer.
"It's alright. It's suggested in the name Yin-Yang Joyous Unification Art after all." She replied trying to hide her embarrassment.
She hugged him back and put her head on his shoulder trying to be closer to him.
Time passed as they stayed in that position with their bodies connected, it did relieve them for a bit but soon that wasn't enough anymore.
Liu Zheng slowly stretched out his hand to caress her neck, pulling her away from his shoulder.
"Su Yan" He said softly as he looked into her eyes but she tried to avert her face as she felt nervous.
He pulled her even closer to him by her and slowly turned her face towards him with his hand.
Liu Zheng didn't think twice in linking his lips to her. A soft and smooth feeling suddenly assaulted him.
At first, Su Yan's body froze solid due to the sudden kiss but she slowly accepted him at her own pace and soon Liu Zheng' tongue split apart her could lips entering her mouth.
The kiss started to slowly become more and more passionate as the sound of periodic sucking resounded throughout the main hall and even Su Yan was fully emersed in the experience as she wrapped his neck with both his hands wanting for more.
He started by slowly caressing her face when they were furiously kissing each other and made his way down slowly.
Liu Zheng slowly grabbed her breast and gave them a light squeeze which even though were covered in layers of clothes felt like one of the softest thing he has ever touched. He kept his hands there for a little while to check for any rejections but there was none so he slowly started to loosen her clothes and one by one they were all removed by Liu Zheng including half of his own as well.
Every inch of her body was out in the open and laid down for Liu Zheng to appreciate. Her body was beautiful and her figure was perfect. Every inch of skin was smooth and her breast were not too big or too small, the perfect size to fill his two eager hands.
Liu Zheng was not sure why he turned of his logical mind and his little brother took over his movements.
He stretched out his hand to remove to pull Su Yan's arm away which were hiding her breasts. At first, she resisted but soon she let go as well.
He wanted to taste them badly and so he did.
"Aaah" a moan brought him back to reality as he found himself not only sucking on Su Yan's breast but lightly biting her as well.
"Sorry, I wasn't thinking properly" he immediately apologized.
"It's okay" she replied as she kissed him again. Maybe she too had stopped thinking for herself and now her womanly instincts were guiding her.
Due to their situation she was already pretty wet down there but he still decided to go down on her which she tried to block but he lightly started kissing her thighs around her hands which were covering her womanhood.
Slowly she let her hands go and Liu Zheng tasted the divine water from her nether region which he was sure should tasted a bit funny or something like that but was pleasant to taste. He thought of it to be the miracle of cultivation world or phoenix source energy but didn't mind much and continued to use his tongue to pleasure her.
He eventually found her clitoris and started to tease it with his tongue as well and used his other hands to play with her breasts.
Her moans started becoming louder and louder and reached its peak as she came for the first time.
He took his lower garments off and his 9 inch dragon greeted her, ready to ravish anything in his path which made her gulp and look a little scared as he pointed it to her divine hole.
"It will be a bit painful at first so you will need to bear with and the pain will turn into pleasure soon enough." He said and slowly started to enter her inch by inch.
The pain was visible on Su Yan's face but stopping now wouldn't improve the situation at all so continued to entered and very soon reached an obstruction which he believed to be her hymen.
He pulled back until only the tip was left and went back again but this time didn't stop at the obstruction and pierced through it. Su Yan screamed with pain but Liu Zheng started circulating the yin yang joyous cultivation art which helped ease her pain and slowly he was fully inside her.
He stayed like that for while allowing her adjust to his size which did take a good amount of time.
The pain Su Yan felt slowly faded away and was replaced by strange sensation of fullness which gave her an embarrassing urge to sway side by side to feel him more and more.
Liu Zheng feeling her movements and the look in her eyes which only indicated only pleasure decided to start moving himself and slowly started thrusted in and out of her.
Su Yan couldn't help but moan loudly as the thrusting began to get faster and harder which exponentially increased her pleasure and she held his neck with her hands even more tightly bringing him closer to him to feel the heat of his body and started circulating the dual cultivation as well.
The Yin-Yang Joyous unification art gave them a very unique feeling of being connected through mind and body where both of them were filled with pleasure and the Dragon and Phoenix feeling their role has been completed decided to reside in their body somewhere they couldn't be found easily but still inside their body.
They continued like that for more than an hour where they tried many positions and Su Yan came multiple times but Liu Zheng was now reaching his limit as well.
After continued thrusting of several more minutes he thrusted one last time with full force where the tip of his dragon was fully connected with her womb and released his seed inside her, painting her insides white which made Su Yan cum hard again and she moaned loudly.
He continued to cum inside her for more than a minute and completely filled her baby chamber but had no worry since the art converts all the vitality of the seed into energy to be absorbed by the female when circulated together.
None of them were tired and Liu Zheng was still fully hard so after a moments rest both of them continued their previous act.
They mated like animals for 4 whole days which was a result of both having a high cultivation and his high vitality due to the body cultivation art of his but had to stop because her body wouldn't have been able to bear any longer.
In the process, Su Yan's cultivation has risen by 3 ranks and Liu Zheng had also broken through twice as well.
------------------------------------
Both of them slowly opened their eyes when the sun started rising and Liu Zheng looked at Su Yan who was sleeping with her head and hand around his cheat.
"Good Morning, Senior Sister." He said.
"Are you still going to call me senior sister?" She asked with an alluring expression.
"Oh, sorry sorry. I will call you Su Yan from now on." He quickly corrected himself.
They stayed like that for a while cuddling with each other and got up after a while and dressed each other up.
She fixed her hair and changed into a new style indicating her transition from a girl to a woman.
Liu Zheng helped her and couldn't help but stare how beautiful she was and how did he end up with her.
Su Yan noticed him as she smiled and asked "Do you like it?"
"Mhm. You look gorgeous." He replied and put his two hands on her shoulder as he kissed her left cheek and said "Su Yan, I love you."
"I love you too, Liu Zheng" She replied placing her one hand on his hand.
They talked with each other for while and later decided to leave the place which now had nothing but memories.
-----------------------------------------
He had completely turned off the connection to zangetsu before he started talking to her if anyone was wondering.
Folks after writing this chapter I have realised that i don't have it in me to write such chapters more than once a month so if another one comes too quickly I will leave a chapter for it and update it later on when i can. Also I will write first times and special occasions while others will only be mentioned
I hope for your understanding on this.
