Find a way to use them to grow even more powerful.

With no specific plan in mind, the creature simply decided to continue growing. A plan or opportunity would present itself with time. And time was the one thing it had plenty of. Over the course of weeks, the creature continued to defile the two heroines. Testing their reaction to whatever foul thought entered its otherworldy mind. It noticed that several spots on their bodies reacted quite favourably to different kinds of stimulation. Pain, pleasure, more of one, less of the other. Day after day it experimented, taking note of how they reacted. There was potential to be found here, it only needed to find a way to exploit these freshly discovered weaknesses.

The creature directed most of its considerable mind towards finding a way to draw more valuable essence from their bodies and entered a meditative state. The large blue eye that was always glowing with power covered itself with an eyelid made from the same stone that protected the bulk of the eye, leaving the cave in utter darkness as the glow disappeared. Occasionally, if you strained your ears, you could hear the muffled cries of ecstasy as the tendrils continued their relentless ****. Never stopping. Never giving a single second of rest.

Xena and Gabrielle had been trapped in the creatures vile tendrils for what felt like an eternity. They had no way of telling the passage of time. They faintly remembered entering a cave to seek shelter from a storm. They remembered the hot water bath they found, and how they were caught unaware by the strong tendrils spread throughout the water. But every second after that was just pleasure.

Gabrielle wanted it to end. She wanted the orgasms to end so badly, she didn't want to cum anymore, she couldn't even begin to count the number of times the creature had made her cum. But a part of her wanted it to continue, and that part was growing the longer she remained in the creature's clutches. It had been gods knows how long since the cave had darkened, and her last thread of hope, her lover and friend Xena, had disappeared into the darkness. Now all she had left to focus on was the never-ending string of orgasms that the disgusting tendrils managed to **** from her body. The creature had changed the air she breathed several times now, and the effect it had on her was slowly destroying her rational mind.

The first change was to make her orgasms even more powerful than they already were. It did this by making sure her body would not orgasm until the pleasure and need drove her crazy. When she finally came, the **** of her release was so strong that her vision turned white, and she swore she saw stars flying in front of her. The fact that it took the creature only a scant few minutes did not make it any better, as she barely had time to recover before the next orgasm wracked her body.

The second change it made was to her lower body; she was somehow altered so that a powerful stream of her liquids accompanied each orgasm as she squirted wildly when the euphoria flowed through her.

She had climaxed countless times by now, quite possibly thousands, and there was no sign of it ever stopping. Her last rational thought, before yet another orgasm blew away her concentration, was how Xena was doing.

Xena was delirious with need at this point. Her entire mind was focused on a singular purpose; To cum. Anything for that coveted orgasm. She didn't care what she had to do for it, as long as it would result in finally being able to cum. No, not able, allowed. Her body was completely under the creatures control, and her greatest wish desire was entirely dependent on its whim. She had begged the creature in her mind. Pleaded with it for a chance to cum. She screamed, thrashed, and fought against its control, but nothing worked in the end. For the first time in many, many years, Xena was completely at the mercy of another.

She took a deep breath as one of the countless mouths along the tendrils bit down sharply on one of her nipples, causing a fresh wave of pleasure to flow from the hard nub. Occasionally a tendril would snap out, and strike her body in various places. It started mildly, a strike against her back, causing her to moan softly around the invasive tendril in her mouth. Or against her arms or legs, each flooding her body and mind with a pain that was quickly turned into pleasure by her oversexed body. But as the hours slowly dragged on, the whipping would intensify.

It would move to her breasts and ass, each strike slowly intensifying until it was just below her pain threshold. On a rare occasion, a thin but rigid tendril would lash out against her nipples, causing her to moan wantonly as the sharp pain mixed with the overwhelming pleasure, blurring the line between the two until she could not diver pain from pleasure. A precious few times, the thin whip had struck out against her clit. The throbbing, aching bud above her soaking cunt pulsated in perfect rhythm with her racing heart, each pulse reminding her of the glorious orgasm that was kept just out of her reach. Trapped in the darkness, she could not see the whiplike tendril approach, and she let loose a loud muffled wail of pleasure and pain as her sensitive clit was struck.

For an agonizing eternity, but was in truth only a minute or so, Xena balanced on the razor's edge of orgasm. Her entire body was focused on that one moment. She used what was left of her willpower to try and push herself over the edge, but the creature's control over her was absolute. For a short period, she felt her resolve to push back against the creature's hold win and parts of her body and mind would return to her. At that moment, the delicate balance it had established threatened to collapse, and thousands upon thousands of denied orgasms began to **** themself from her exhausted body. The sheer pleasure and anticipation of finally being able to cum broke the fragile defences she had in place and the creature retook control of her body and mind, quickly taking the steps needed to stop the impending climax.

It wasn't until the creature had reviewed each and every possible action it could take, a process that took many days, that the eye slowly opened. It had decided on what to do.

The singular eye began to glow with otherworldly energy, bathing the underwater cave in pale blue light. There was a low rumble resonating through the water, as the cave began to chance to accommodate its master's new wishes.
