Yuki licked her lips while Delia leaned on her, panting. It was obvious that she had just had an orgasm. “Seems the Demon Queen has been defeated.”

“Shh…” Delia couldn’t help but grin. She liked it when Yuki teased her.

“Let’s get in.” Yuki stood up and kissed Delia’s lips before taking her hand and leading the girl into the pool. The two girls sat facing each other, just staring into each other's eyes, before Delia suddenly waved her hand, creating a long, thick, black, double-sided dildo with her demonic qi. 
    
“Oh?” Yuki raised an eyebrow as Delia slowly inserted it into herself before rubbing the other side against Yuki’s pussy. “Just push it in. I will be fine.”

Delia nodded and pushed it in between Yuki’s already wet pussy. Yuki let out a soft moan as she cuddled up to Delia, pushing the dildo deep into her. The two girls began to kiss while circulating their qis.  Delia controlled the dildo so that it would pump in and out of them while at the same time circulating her qi as well. The dual cultivation method began to turn, and Yuki’s sixth primordial core began to take shape.

Tongues tied, and their bodies entangled even as Yuki broke through; they showed no signs of stopping. The myriad pool they were in was slowly dimming as well as the spiritual qi was being sucked out of it. 

“Delia…” Yuki whispered as she moved her hips back and forth. “I am so happy. I am happy that I have you here with me in this world. I am happy we can share our love for one another. I am happy we can be doing this so freely.” 

“Hehe… Me to. Seeing you move your hips in motion with mine. The lust-filled look in your eyes just makes me want you more and more. Yuki, I am so in love with you it’s not even funny. So, please, show me more of you. I want to know everything about this new you from head to toe.” Delia leaned in and kissed Yuki’s lips before trailing down her neck and to her breasts. She pulled the perky nipple into her mouth and began nibbling it all while stroking her tails one by one. 

As time passed, the spiritual qi and demonic qi in Yuki’s body began to grow more and more. She knew if this kept going, she would end up shattering her cores, and the process of creating a nascent soul would start. Once she reached this level, she would be one step away from becoming an immortal.

Delia also sensed this and calmly whispered into Yuki’s ear: “It’s fine. You can break through. I will keep our qis circulating. As long as you trust me, you can break through.”
 
“Mm… I fully trust you. So let’s keep going.” Both girls were sweaty from the continuous sex, but they did not care. Delia took control of Yuki’s qi and continued to circulate it while she began working on shattering her cores. 

Core chattering was the final step to the primordial core realm. Unlike a universal core, which still had you shatter the cores, it was only to form a lesser version of a nascent soul. The process was not very easy. She had to concentrate on the first core she created and then shatter it before moving to the next. Each core had to be done one at a time before moving on.

“What do you think Yuki is doing?” Nana’s mind was only about how her Yuki was doing. She felt as if part of her was missing when Yuki was not around. 

“She is probably cleaning up. Yuki is much stronger than any of us think. I can tell. I always look for strong opponents to fight, and Yuki, so far, has made me see what true strength truly is. She has shown me just how strong us mystic races can be if we work hard.” Selene had a small smile on her face as she spoke about Yuki. At some point, her mind had become filled with the fox girl as well.

“Yeah, since I have met you, Nana, Yuki’s strength has truly become something I can only dream of. She has become so strong I fear being left behind.” Silvia always had this lingering fear as of late that Yuki was truly going to leave them behind. She did not want that. Not after understanding what true love was. Yuki and Nana were her world now. She loved both of them and did not wish to be left behind.

    “Yuki would never leave us. Even if she had to wait hundreds of years for us to catch up, she would wait patiently and protect us. That is just how Yuki is.” Nana stated firmly. There was no ifs, ands, or buts about it. To her, Yuki was someone who cherished their relationship more than anything. She had not been with Yuki this long for no reason.

“I know this as well. I just can’t help feeling scared sometimes.” Silvia let out a sigh. She grew up as an assassin. She had no family. She had nothing. But now she had Yuki. She had Nana. Even Delia was now part of their group. She knew very well that Yuki would not let them down, but she couldn’t help but feel scared sometimes.

“Silv….” Nana hugged Silvia and kissed her cheek. “Never doubt Yuki. She will never leave us behind.”
