The three girls emerged from the dressing room at the same time, oohing and ahhing at each other's attire. Monica had to struggle a bit in her shackles. A short chain connected her ankles with a longer, heavy chain attaching to her wrists. She struggled forward to take a look at her friends.

"I love those boots, Gina," Monica cooed, much to Cindy's disappointment. "You look amazing! Like a latex dream!"

"You look great, too, Monica," Gina returned. Cindy was upset nobody admired her, though she felt pretty good in the latex bra. She was certain, at first, that the man had given her too small of a size. But as she stepped out of the dressing room, nearly running into a man clad in leather, he whistled at her breasts, staring directly at them. She pressed her chest out and smiled as he slid by her. It was as if she had a second skin of rubber over her large breasts, barely holding them into place.

"Let's get this over with," Gina moaned as she gestured out to the casino.

The three girls stayed together for awhile, supporting each other as they walked and experimenting at some of the tables. They stayed away from the far wall where the alternate games where kept, choosing to survive at blackjack and roulette. Monica seemed to be possessed when gambling. Gina and Cindy often had to drag her away before she lost too much. Before long Monica had depleted her chips. As they walked back to the dressing room to allow Monica to change, Gina took a quick look at her winnings. In contrast to Monica, she had done well on her meager bets, winning a steady amount to nearly double her chips. She kept this to herself, not wanting to give Cindy or Monica a reason to envy her. She knew Cindy was down a bit, but was eager to try some of the more adventurous games. As they made it back to the dressing room, Cindy caught sight of something and said she would see them later. Gina shrugged and helped Monica to the desk.

"Back already," the man snickered.

"I guess I'm not so lucky yet," Monica complained. She picked up a book and started flipping through it. She quickly realized it was different from the one she had looked through earlier. "Wow, these are amazing!" Rather than the simple outfits of the previous book, this contained the more extreme equipment that earned the higher sums. Gina looked over her friend's shoulder and found herself imagining Monica in the outfits.

"Try that one," Gina encouraged as they looked at a hobble dress and arm binder.

"I don't know. How will I bet?"

"I'll be with you. Don't worry. Besides," Gina glanced at the $3,000 figure at the bottom. "You need the money." Monica smiled and agreed, pushing the book toward the man. He smiled and winked at Gina then disappeared to get the items.

Gina loved this. Her hand gripped the leash attached to Monica's collar as they walked through the casino. Monica was far more concerned about learning to walk on the seven-inch heels. She was glad the hobble dress, which fit snug to her perfect form, only allowed her to take a four inch step. But her shoulders had begun to ache and she was getting tired of the inadvertent grabs she got from the crowd. Gina seemed to be ignoring them, and Monica could do little to fend them off. The attendant seemed to take particular pleasure in lacing up the single glove that now encased her arms. As the straps where pulled tighter, she could feel her back straightening and her shoulders being forced back. It wasn't until she could feel her elbows touching that she knew there was more to this arm bondage than she thought. But despite her complains, the man had simply ensured the straps where snug and added the small padlocks that now held it into place.

"Where do you want to go," Gina asked over her shoulder.

"Someplace close," Monica complained, stumbling again. "How about that blackjack table." As usual, the table Monica had chosen was a minimum $100 bet, which Gina knew wouldn't discourage her friend. Thankfully, Monica slipped onto a stool in between two others, taking the weight off her toes. "I can't believe people walk in these things!"

"It's training," the man to her left spoke.

"I'm sorry?"

"The shoes. It takes training and practice to walk in them comfortably." Monica smiled at him in response. He was young and very handsome. She tried to look sexy but found it difficult without the use of her arms. As the dealer prepared to deal, Monica gestured for Gina to make a bet.

Cindy had quickly forgotten about her friends. Though the bizarre casino was taking some time to adjust to, she did see the potential to win. The far wall of the large room was a maze of interesting, and often painful or degrading challenges. Though many weren't at all her cup of tea, Cindy was eager to compete in some. Some of the games simply required the player to take a spanking without crying out, though some of the spankers seemed to take particular relish in their jobs. Other attractions offered anything from suspension to piercing. A short row of port-a-potties reminded Cindy that she had to pee. Upon entering the largish room, she realized this was another game. A young girl was strapped on her knees in the bottom of the toilet so she could not move. A large funnel-like basin was attached to her mouth. Cindy quickly realized that this girl was being used as a human toilet. Already her stomach was distended from the various waste products she had consumed. It took a moment for Cindy to understand the game. It wasn't until she examined the poor girl's bound arms that she saw the thin string she held in her hand. At the opposite end was a bell. She could see that once the girl had had enough, she could ring the bell for release. A sign on the wall caught Cindy's eye. It explained that the girl would receive $1,000 for every half-hour she performed as a toilet. Shrugging, Cindy stepped up to the basin and, watching through her legs, peed into the girl's mouth.

Slipping out of the toilet, Cindy immediately caught sight of a game she would be good at. It was labeled "Maintain your balance" but seemed far too simple for a competitive game. Nobody was currently taking the challenge so Cindy had to use the text to figure it out. She would be in a standing position. Her arms would be tied behind her back and special clamps would be attached to her nipples. The attached cables where fed over a bar above her then attached to s flat weight. The goal was to keep the weight off the plate. For each 30 minutes, she would win $5000. But each time the weight struck the plate, she would be charged $500. It sounded easy to her, so Cindy jumped up to the platform.

"I'll take an hour," she said to the gamekeeper. She was a little upset when she was asked to disrobe, but she was proud of her body and enjoyed the stares from the men and women gathering to watch. An attendant tied her wrists together behind her, then slipped a cool leather strap around her elbows. Cindy could feel her breasts pushing out more as her arms where bound tightly together. It was a curious feeling, being bound this way. She felt like her chest was on display now, something she was quite comfortable with.

She was positioned in the middle of the platform as another attendant placed a wide spreader bar between her ankles. Her long blonde hair was laced into a ponytail and a strap tied to it was pulled to her elbow strap. She could feel her hair being pulled back until her face pointed to the ceiling. Her eyes where quickly covered with a tight blindfold. OK, she thought, this is an interesting twist. I'll just have to guess the distance rather than seeing it. With her legs spread, she would have some trouble balancing, but she put it out of her mind as she felt the cool clamps being placed on her nipples. The teeth bit into her skin, making her wince, but Cindy was determined to be tough. One of the attendants pressed a gag to her lips and, as she opened her mouth to complain, the penis gag slipped between her jaws. It was huge, filling her mouth while cutting off her complaints. Hands helped her keep her balance as the weight was hung from the end of the cable. Cindy grunted in pain as it was released and the clamps bit down harder on her nipples. She immediately leaned back to keep it high off the plate she could no longer see. She had guessed the game had started until she felt some fumbling at her spreader bar, then a cool shaft of steel was pressed into her pussy. The metal dildo was pushed deep inside of her, the thickness filling her completely. She had no idea why this was a part of the test and, despite her initial anger at this intrusion, she actually enjoyed the feeling. Finally, all hands left her and she began focusing her task.

The sight of Cindy on his platform excited the gamekeeper. She was beautiful, with her thin body and large breasts, bound tightly and legs spread. The metal bar that kept the dildo in place was locked off and the wires where run from the end of the shaft and to the plate. He flicked the switch to power the device, then flicked the timer and tally board. The audience was excited and, though early in the game, where already tense. It was only a matter of time, the keeper knew.

Cindy was a little disoriented. With he head pulled back hard and her lack of sight, she was having trouble telling which way was up. She just focused on leaning back, though how far was a concern as well. After what seemed like hours, but had actually only been ten minutes, the weight brushed the plate. A sharp shock shot through the dildo and into her pussy. She jerked back hard, pulling the weight back up, grunting at the harsh bite of the clamps. So, that's the trick, Cindy thought. I'll just keep back even more to prevent...

The keeper watched Cindy rock forward again and the shock that struck her pussy brought her back hard again. He smiled. This was going to be fun!

The shock to her pussy had hurt, but she could feel her excitement rising as well. The lubricated dildo was even more wet now as she felt her juices coating it. She was panting now, trying to stay focused. She knew she had lost $1000 already. If she could only stay back for a full 30 minutes, she could offset that money and still walk away a winner.

As usual, Monica was running short on cash. Gina was bored, having been used as a servant by Monica wasn't her idea of fun. She had gotten rather chummy with the young man beside them, maybe he could bet for her.

"Monica, I have to go to the bathroom," Gina whispered.

"Yeah, go ahead, Gina," Monica said out loud. "This gentleman will assist me, won't you?" She smiled at him with her best smile.

"It would be my pleasure," he said.

"OK, I'll be back."

"Take your time, Gina," Monica winked as she turned back to the man she was trying to pickup. Gina slipped into the crowd, eager to have her own fun.

Cindy wasn't doing too well. The weight had touched the plate at least seven times and she was gasping in excitement. She tried to keep her back straight and the cables taught, but she had lost all sense of balance and could not regain it. She was rocking back and forth, trying to control her seething body and keep the weight up. It was only a matter of time before it touched again. The shock sent her over the edge. Her orgasm made her buck on the steel dildo as the weight skittered across the metal pad beneath it. She jerked back hard, but the slight shift of the dildo sent her over the edge again and the weight crashed down hard, completing the connection once more. She could no longer control it as she came again and again, the metal connection sending shocks through her.

The current stopped and Cindy slumped in her bonds as best she could. The keeper slipped off her gag and blindfold.

"I'm sorry, but you have completed your first 30 minutes and owe us $7000. You can pay us now or go for double or nothing." Gina knew she had only the $1,000 on her. Her competitive spirit took over again. "I'll go double or nothing," she said. The crowd cheered her on as the keeper shrugged and replaced the blindfold and gag. She could feel another attachment being added beneath her. A cool pressure against her asshole told her what it was. The second steel dildo was pressed into her ass until it was buried deep inside her. Cindy moaned at the intrusion, but could feel herself getting wet again. She had always had a thing for anal sex, though it was hard to find a guy who would work at it slow. It wasn't until the hands left her that she realized that an electrical shock would rise through her ass now too. She began to panic as she felt a heavier weight being applied to the cables. A voice from behind whispered to her.

"Up on your toes." She rose up as the attendant placed small boxes beneath her heels.

"Ladies and gentlemen. This lady has chosen to go another 30 minutes at double or nothing." A cheer rose through the crowd. "She will be forced to stand on her toes this time, with a dildo in both her ass and pussy. If she falls back on her heels, the current will be stepped up." Cindy tried to relax her feet but felt the button beneath her. She would have to stay high on her toes to keep off the box. Her nipples where screaming beneath the crushing teeth of the clamps. She tried to focus, leaning back to hold the weight up, but not too far to fall back onto her heels. It only took a moment before she lost balance and landed on the buttons. The shock that ran through her pussy and ass was a sharp contrast to the previous shock. She wasn't sure if it was the higher current or her newly punished asshole, but she found herself quickly jumping back on her toes. Of course as she did this, she leaned forward too much, allowing the weight to touch again. Despite her pain and frustration, she could feel a new orgasm building inside of her.
