Exodus

A soft glow crept from Deci's palm, the rock taking on the same glow after a minute or two. When the glow died down a soft ddddddrrrr sound could be heard coming from the rock. It continuously and rapidly moved to and froe without actually shifting its location on his hand. He walked up to Vixen and put the rock against her clit. Immediately a shock went through her clit to her nipples as it dissipated throughout the rest of her body, but she didn't orgasm. 

"Are you sure," asked Deci one last time.

Vixen nodded in affirmation and steeled herself before, with a little force shoved the stone deep inside her. Vixen immediately fell, her fluids drenching the sand beneath her, but she managed to hold it in. 

'This is crazy, my insides from my womb to my clit is vibrating.'

"Best of luck," said Deci as he walked away laughing. 

Vixen had her arms wrapped around her abdomen, hunching over. She felt if she turtled she could mitigate some of the sensation, but she was wrong, nothing seemed to lessen the feeling. 

'I'll try to take my mind off of it' she thought to herself. "G-Galmora, want to join me in the ocean for a hunt?"

"Sure, that sounds nice, though are you going to be ok in your state?"

"Not sure, will, mhmm, have to make due."

The two of them dove into the water, Vixen was struggling to keep up since Galmora was born to be in the water. She possessed the [Amphibious] ability so she wouldn't drown herself. They went a couple hundred feet down where the bigger fish resided, she needed a challenge to focus on. 

They ran into a humanoid fish type monster; it had the head of a piranha, the body of a hunched man, and incredibly webbed hands with sharp claws. It torpedoed through the water at incredible speed and headbutted Vixen in the stomach, the force made her fly through the water at the same speed she could swim. It hurt, but she received minimal damage due to her defensive ability. She swam to meet it swiping her own hands, but her movements were incredibly slowed by the water. 

The monster seemed to laugh, then it stopped. The squishy appendage on top of its head twitched, then it began to move similarly to how a dog nose would when excited about a particular smell. The appendage grew stiff and the monster seemed to smile as a large ugly green dick protruded from a hard casing in its pubic region.

Deci was sipping something from a goblet in a familiar cave, Naix sitting across from him sipping the same liquid in a similar goblet. "You seem to be in a particularly good mood. What happened?" Asked Naix between drinks.

"Well, I pretty much just got a free slave for a year," Deci responded, "there hasn't been a woman dragon or otherwise who has been able to win my game." 

"She actually accepted the conditions huh?"

"Aye, she did. What's better is that I gave rules that prevents her from doing anything the stone but nothing that says I could not."

"With as sensitive as that woman is I doubt she'll win either."

"I know what you mean, she nearly lost upon insertion. I can make stronger by will and it'll immediately tell me if she loses so she cant lie about it."

"How long are you going to drag it out?"

"Well it has been going on for three hours now, maybe I should end this now?" Deci put up three fingers, "This represents its current power, lets double it for now," he said laughing.

******************************************************

Vixen managed to kick the monster away, it had become significantly more aggressive as if getting into a mating fervor. She couldn't move fast enough to be aggressive and remained on the defense. She kept her legs closed, she wasn't going to allow this monster to have its way with her and started to channel her mana in preparation for a spell.

 It came without warning, the dull drone from her crotch increased significantly, forcing her to double over to help her focus. Her juices dripped out of her, her nipples hardened, and took every ounce of her willpower to not orgasm, but the moment of weakness excited the predator greatly and it jetted towards her. The monster bit her shoulder and squeezed her arms to her sides. She quickly placed her hands over her crotch and she could feel the monster grind its dick on the back of her hands. 

"You're not the only one who can bite," she said sinking her teeth into the monster and more successfully than the monster itself. She began to drain the monster of its blood. The monster had only one focus and didn't notice its blood loss until its eyes slowly grew cloudy and its body still.

'Thank god that monster bit me, it probably saved me.  Ive gotten in control of it but this is killing me, it didn't occur to me he could make it stronger...'

 After nearly thirty minutes the supercharged rock died down again giving her a little reprieve dropping some of her focus. She tested her new ability and found that she could move much more quickly in the water but by temporarily reducing her breasts to a B cup she was able to go even faster. They would revert automatically after an hour or so. 

She spent several hours under water fighting, it was the only thing she could do to focus enough to keep herself from cumming. 

While she was under water there was not another bout of powerful vibration and by the time they returned to the beach she had been underwater for five hours. 

She had only taken a few steps onto the beach when the intensity inside her increased again, and a moan mixed with a determined growl escaped her lips. She punched the sand as hard as she could focusing on anything she could to distract herself.

'This is even stronger than the last time,' she thought. 

Again after thirty minutes the intensity died back down and she breathed a sigh of relief only for it to come back again a moment later. She almost came from the surprise, but managed. The stone alternated between high and low intensity for three hours.

She refused to relax her focus even a little for fear of being caught off guard.

**********************

"Still holding on is she?" Naix teased Deci who had looked so smug earlier. 

"Sigh, I really wanted a slave but I grow tired of this game. I'll go tell her she wins. Want to bet she'll cum immediately when I do?"

"I don't gamble with you"

"Suit yourself. "
