A Braixen Pokemon eagerly walked up to a casino and flashed his identification. His ID came with his name, Crimson. The ID also included his age, and he included his wallet to show he was ready to play some casino games.
 
Crimson stuffed his wallet back into his fur and glanced around. He saw various donkey girl servers, and some attached to walls with their udders filling up drinks for customers. He knew this was a strange kind of casino. This casino was modelled after two of them. In one way, every server was female. In another way, one person could bet their body in the casino. If they won, they could transform that body part in any way they so picked. However, should they lose, the casino transformed part of their body.
 
Crimson eagerly wanted to get a toned body, with which he could impress anyone around him. He figured he could just get some muscles and then maybe walk out. The casino usually won in these sorts of transformations, especially if the donkey girls were anything to go by. Crimson wasn't afraid though. He just wanted to get maybe one or two transformations, and then he'd walk. He wasn't greedy.
 
With a deep breath, he figured he'd start with something simple. He walked over to the slot machines to place his first bet. 
As he pulled the lever of the machine, he immediately flinched and closed his eyes out of fear of losing. The wheels inside the device kept spinning for what felt like an eternity, the machine sounded a loud ring and started flashing. 

"YOU WON!" the machine exclaimed to Crimson's massive surprise. Before he could even process what happened, a string of text suddenly appeared on the display and asked him to state a wish. Still in a state of shock, the young Braixen thoughtlessly exclaimed: "I wish to have rock-solid abs." As soon as he finished the sentence, he began to feel a pressure underneath his shirt. Happily, he lifted his shirt and bore witness to quickly growing lumps on his abdomen. Upon touching them, he felt as they grew denser and harder with every breath he took.

However, just as he was about to proudly walk out of the casino with a grin on his face, thinking he had outsmarted their system, he found each step to feel increasingly stiff. It wasn't as much that his legs weren't compliant, but rather was it his torso that refused to swing along the natural rhythm of each step. 
As Crimson clasped his hands around his abdomen, he was shocked to find that his muscles were still getting harder. While they still had a bit of a give to them, any real motion he had control over seemed to vanish entirely and left him with abs worthy of Adonis. 
Raising his shirt once again quickly corrected Crimson's misconception of the situation, as he found that his belly had turned into a smooth, gray surface, which felt cool to the touch.

In a fit of anger, Crimson gracelessly and sloppily waddled to the nearest person, who he thought resembled a staff member. "Can you explain what has happened to my torso?" Crimson snorted angrily at the horse anthro in front of him. 

"That isn't the politest way of saying hello. How about I start with a 'Hello, I'm Myu and I'm the manager of this casino. What can I do for you, sir?'" Myu replied, while looking at Crimson with a smug smirk.

"I am not in the mood for games. I won at the slot machine, and I was screwed over. I wished for..." Crimson wanted to continue but was interrupted mid-sentenced by Myu. 

"For 'rock-solid abs', which is exactly what you got, now isn't it?" Myu asked. "We're a casino; we'd be dumb not to have cameras all over the place. It's a safety thing, you understand."

Upon hearing this, Crimson froze in the spot with a horrified expression garnishing his face once he realized his mistake. Wordplay was the downfall of most people making wishes against a bad genie, and in this case, the casino.

"I'll tell you what. You probably don't even know how you won at those slot machines, so I'll give you a deal. Let's play a simple dice game. I'll roll these two dice, and then you roll the same dice afterwards. If you get a higher number, you win and then you can select a transformation, such as returning to normal. If you lose however, I will transform part of you. All you have to do is win once to transform back to normal, or you can try to win repeatedly and get your wish right." She looked away briefly before she looked back at Crimson. "One person wished for a good lawyer. Not that they sued the place, but a lawyer knows how to get around wordplay very well. Just a suggestion."

Part of Crimson wasn't sure whether he should agree to such terms. It sounded like he just had to win once, but he questioned how likely that win really was. They were using the same dice though, so any weighed dice would be out of the question.
In addition, with his current conundrum, he really didn't have much of a choice. He only needed to win one single round, and with the same dice Myu used. "No magic involved or anything like that?"

Myu shook her head. "Magic is strictly forbidden unless used by the casino to cause transformations. I may be evil, heartless, cruel, maniacal...okay I could go on, but the point is I'm 'not' one to break rules, especially when I set them!"

Crimson nodded firmly with a serious look on his face. "Okay. Deal."

With an almost devilish smirk, Myu began her turn and rolled a nine. "Well, this is a fairly good roll. Your turn." She used two ordinary looking dice with the casino's symbol on the 'one', the symbol being a female donkey anthro head.

Crimson could tell Myu enjoyed that roll far more than she showed. He could tell something wasn't right with her, or the casino for that mattered. He was already in this for the long haul though. Fixing his chest was not going to be easy if he walked out. Crimson quickly threw the dice and waited for them to stop rolling. His heart sank when he saw two threes.

"A pity, it looks like you lost this round. Now, since you wanted to have rock-hard abs, how about making your cock hard as well." 

Immediately after saying that, a wave of lust flushed through Crimson's mind, as an erection formed underneath his fur. He blushed underneath his fur and turned his eyes to see a server looking on with a smile. The Braixen was nude, as Pokemon usually were. He began to regret the choice not to wear pants. It wasn't that his cock was small. He was quite well endowed. It was the fact he was so endowed that he couldn't hide that erection.

"I can imagine how much you would want to relieve that rock hard cock. Unfortunately for you, this violates the house rules and is punished with becoming a donkey waitress." Myu commented on Crimson's peculiar state. "You 'could' go to the bathroom, but I'm not going to wait here long. I am a terribly busy horse. I'm so busy that sometimes I let people control my body so I can do other things." It sounded confusing, but it'd make sense to the person that 'did' control her, if only partially.

He found it hard to resist touching himself with so much arousal in his mind, but he knew he had to keep his composure. "F-fine. Another round then." He just had to win one. How many rounds could he lose?

Myu took her turn to roll her dice. 

As her dice stopped rolling, Crimson's eyes sparkled with hope as he saw her roll a three. 'Hah, where are the witty remarks now?' Crimson thought to himself victoriously, feeling certain of his chances to win.

"Well, there's still a small chance you could lose, or even tie." Myu sat back and crossed her arms over her tits.

Crimson wondered what happened in the event of a tie. She hadn't explained that bit. She just said what happened with winning or losing. Still, there was no way he could lose against that roll. He rolled his dice, and his jaw dropped at the result.

"Two. You lose." Myu replied calmly. "Overconfidence is unbecoming, you know. The game isn't over, until it's over." 

Crimson couldn't help but stare in disbelief. Was this game rigged? The chance of him rolling the lowest possible number was incredibly low, especially after Myu rolled her number almost just as low.

"As your next transformation, how about making your cock hard?" Myu suggested. 

"But you already said that in the previous rou..." Crimson found himself unable to finish his sentence, as a strange, yet familiar feeling emerged from within his erect dick. He reached down to touch his cock, but he felt an odd coldness to it. He glanced down and saw his cock was as gray as his chest, and the gray spread downwards. He felt as if he were ready to orgasm, but with his cock now made of stone, he knew that was likely impossible. His cock also felt much heavier. He felt as if he were going to fall forward with its weight.
 
 "I like themed transformations, what can I say?" Myu giggled. "At least you can't orgasm out in the open now. You can technically stroke yourself all you want, but that might be in bad taste."

"What kind of devil are you?" Crimson already regretted ever agreeing to this deal. This game seemed to be rigged from the start.

"I'm no devil. I'm simply a horse who likes to have fun. So, let's continue this fun little game!" 
It was time for the dice to roll once more, as Myu rolled, and they landed on a seven. "Your turn."

Crimson wondered if there was there any way to win this game. By now, Crimson would have expected to win at least once. Statistically speaking, there was no way he could lose every round. He wanted to back out of this now, but he'd unlikely ever change back. He couldn't live with a rock-hard stone cock. It felt as if his cock were constantly edged, and he couldn't stand it. He rolled the dice, and they landed on a seven. "Well, a tie. Do we both get a transformation or..."

"Oh, we keep it simple." Myu commented. "You lose."

"What? How can you say that? We both rolled the same number!" Crimson was outraged.

"Before you blame me, remember the rules of the game. I clearly stated that you win if you roll a higher number. We never covered what happens in the event of a tie. I did mention it earlier, and you 'could' have asked, but you didn't. Again, the whole lawyer thing helps here."

That was the last straw. Crimson knew he had to get out of that casino immediately. Living with permanent erection and abs of stone would surely impede his life, but at this point, anything was better than continuing this game. 
As difficult as it was to move, Crimson focused his entire energy and ran for the door.

"To keep up with the theme, why don't we transform your legs and feet into stone?" Myu suggested. "I'd say something about rock-hard, but I think we all know where this game is going by now."
 
Myu's words resonated within Crimson's entire body. He tried to run, but each step felt harder, as his movement became stiff, and a sensation of numbness started spreading through his legs. His fur took on a gray color and grew hard. He found himself unable to move at all to the door with his legs. He tried to make for the door anyways, but he nearly fell. The only reason he didn't fall was that a donkey girl managed to catch him and turn him back to Myu.

"I don't want to be 'that' evil." Myu commented. "If you fell down, your cock would shatter on the carpeted floor." She swore that part of the floor was wooden, but it would not be a bright thing to have a wooden floor in a place full of donkey girls with hooves to scratch it up. "And we can't have 'that' now, can we?"

"I want out! I quit! I'm done!" Crimson shouted. He could still wobble, but the donkey girl that helped him earlier seemed to hold him in place.

"Hey, if you tried to fall forward, you'd shatter your cock. If you fell backward, you'd shatter that tail and stick. You're stone from the waist down, but you're not invincible." She put her head on top of her fingertips. "If you quit now, you forfeit and technically lose. I can't force you to stay. Okay, I guess you can't exactly go anywhere anyways." She said with a laugh. "But I can always tell John there to let you go so you can fall freely."

Crimson glared at Myu angrily. There was no way out of this now. If he quit, he'd likely transform into a statue of some sort. If he continued, he'd likely transform into a statue anyways! There was no way out of this for him. He just had to keep rolling and hoping he'd win. "Fine." He said with a groan. He'd keep betting and playing until he won or lost. What was the worst that could happen?

A few hours later...

"Set him up right there, and perfect!" Myu said happily. "Now, all of those bells and whistles were set up during the bet, so just flick the stick on his tail and he'll be ready."

A donkey girl flicked the stick on a familiar looking Braixen, but the Braixen had a new form. He was now that of a fountain, a fountain where water sprayed out from his cock, sending the Braixen into an endless sea of an endless orgasm. He'd spray water into the fountain that surrounded him. Water flowed back into his body, and back out of his cock again. His face was a look of pure pleasure, something that he lost during the betting process.

"I don't think it fits the theme of the casino honestly." Myu commented. "But I got to say, turning a fire type into a water type is pretty amusing." She said with a laugh. Unlike many others that changed into inanimate objects in the casino, Crimson hadn't accumulated any debts, so the only thing that kept him a statue was because of losing a dice game, one that Myu wasn't likely going to change the results of anytime soon.
