Using her cultivation vessels

Alea produced one of the pills from Kass' pouch and popped it in her mouth. Using the same trick Kass had nearly gotten Alea with, Alea planted a sloppy kiss on Thali's mouth and invaded Thali's mouth with her tongue. She toyed with the beta for a moment before transferring the pill over during the kiss. Thali looked up in confusion as she felt the pill enter her mouth, but Alea pulled away and explained.

"Your cultivation vessel duties begin today, Thali." Alea said. "I wonder how loyal you'll be to me with a bit more Resolve in you."

Alea ordered Thali to swallow the pill and cycle its energy through her body according to Alea's instructions. Thali had said she had no talent for cultivation, but she was noticeably more efficient at refining the energy than Kass had been.

She was still nowhere near Alea's level though, and Alea pressed her hands against the beta's sides so she could do what she could to minimize the loss.

While helping her, Alea kept a careful eye on Thali's face, waiting for the slightest sign of rebellion or alpha urges.

She saw the first twitch of defiance appear when Thali reached the first layer of Resolve Condensation. Alea waited for a moment, sitting and watching Thali.

Thali trembled, glancing at her hands which felt magical strength they'd never known before. Then they glanced up at Alea, and without another word she stuck her head back on Alea's cock, licking and lapping at the remaining fluids there.

Alea's cock quickly went hard again, and Thali wrung it until the first drops of precum were oozing out of the tip. She lapped at the small droplets as though they were heavenly elixirs of immortality. Only when she'd polished Alea's cock a second time did she finally explain her sudden eagerness to suck.

"Forgive me, mistress." Thali said as she prostrated herself before Alea. "For a moment, I had a thought unbecoming of a cultivation vessel. I wasn't strong enough to resist temptation until I had more of your fluids inside me."

Alea patted Thali's head, then pulled her close until the beta knelt between Alea's thighs. Alea hugged Thali's head to her stomach possessively. "Shh. You did better than I ever dared to hope." And Alea truly was pleased. At the third layer she could have easily overpowered Thali at the first sign of rebellion.

But Thali didn't know Alea was at the third layer, for all Thali knew the two of them were standing at the same level. Alea had feared that Thali would take this as her opportunity to turn the tables on Alea and take Alea's cultivation for herself, but instead the submissive cultivation vessel had willingly reasserted her role as Alea's possession.

Without another word, Alea pulled Thali onto the bed and rammed her hardened cock into the futa's pussy. The warm throb of Thali's body felt comfortable around her, and Alea sank into meditation as she fucked.

In and out she went, and with each thrust she cycled Thali's new Resolve around her body. Though Resolve was pure magical energy, its influence could affect the physical world. One of those ways was in appearance, where collecting more resolve could make a futa physically more muscular and capable of performing feats of great speed and strength.

Why was that?

Alea observed the Resolve in Thali's body and began to notice tiny changes with each cycle. There was a scar on one of the tendon's in Thali's wrist, likely from an injury sustained her travels. With each flowing wave of Resolve the scar healed a little more, leaving behind unblemished flesh. There were a few small scraps and cuts on her skin from being roughly fucked in the woods who knew how many times. Those too were healing without the slightest trace.

More than that though, the Resolve was perfecting her physical form, Her skin lost its blemishes and took on a healthy luster. Her nails became flawless and smooth. Her teeth straightened and her eyes shone with greater intelligence. Her muscles straightened and went taught, toning her body and imbuing her with a sense of grace that wouldn't be lost even after Alea plundered the Resolve making these changes.

Alea wanted to see where this line of thought led, so she fucked deep into the night, holding herself back from orgasm as she observed Thali's body. The futa beneath Alea panted and begged for her mistress to stop teasing her and just let her orgasm, but Alea was afraid that would disrupt this natural process, so she simply kept Thali on the edge throughout the night.

As the night wore on, Alea's observations gave her a deeper understanding of Resolve, beyond what her book had taught her. She learned to grasp the Resolve in Thali and take charge of the changes. She wanted her cultivation vessel strong and healthy, but at the same time she'd prefer to give her a more sensual and naturally submissive figure.

Thali would prefer that as well, Alea thought.

Gradually, Alea confidence grew and she began directing the Resolve in Thali's body exactly the way she wanted it to work. She enlarged Thali's breasts, plumped her lips, widened her hips, and got rid of that annoying futa cock and balls still between her cultivation vessel's legs. It was already small to the point of uselessness, and it wouldn't be something Thali would need from now on.

Alea used three more Pill's of Resolve on Thali, leaving her with five. She tapped most of the new Resolve from Thali's body and pulled into herself so she could get closer to the fourth layer of Resolve Condensation, but decided to leave Thali with a cultivation base of the first layer. Cultivation was one of those things that functioned faster the further along in the process you were, so investing a little power in Thali would make gathering more easier for her, which in turn would leave more available for Alea the next time Alea fucked her.
