Once the bouncer let her through, Holly let out a nervous sigh. Now a long hall stretched before her, with an unattended coat check to the right. The warm September day left little reason for a jacket. The hall was well lit, with green carpet stretching into the room through the doorway at the end. She tugged at the hem of her little black dress and walked down.

The room was huge, with felt-covered card tables everywhere, and roulette wheels and craps tables here and there. The men wore suits and the ladies cocktail dresses, and Holly felt distinctly under-dressed as she looked around. The waitresses all had on the typical Vegas skimpy outfits, with hose coming out from tiny black shorts, and shiny gold tops with lapels that framed the cleavage between. Strangely, some men and women wore only thongs or other lingerie, and most of those had collars on with leashes attached. Another bouncer blocked her way, pointing to the chip counter to the left. Shaking her head, she moved towards it.

The minimum buy in was a little scary. She’d been warned by her sister when April had called, but the shock of seeing the sign with $5000 as the minimum number of chips she could get still resonated. Her hands shook as she reached into her purse and pulled out the hundred dollar bills from her college fund for this semester. The 50 chips that came back were unmarked, but the math was obvious. Clutching the small tray they were in, she turned to walk onto the floor.

Another look and the strangeness of the gambling club sunk in. The few leads in the real world all had pointed to a dark web site that told her only the gambling was high stakes and things other than money could be wagered. The hints that even your body could stood out in her mind, particularly with the leashes on display. She wouldn’t go that far. Her fifty chips would have to do.

Holly really didn’t want to be here. The panicked call from April played through her mind.

“You have to win me back...”

The cops hadn’t found anything when she’d told them she had a lead on her missing sister, assuming they’d even bothered to check. She doubted it. There was no way an illegal gambling operation like this could survive even a cursory inspection.

Taking a deep breath, she stepped down onto the gambling floor. Hesitantly she walked around, not entirely sure what to do. The well-dressed men and women checked her out, and some signaled for her to join them at tables. All of the scantily-clad people studiously ignored her. Holly was not at all sure what she was doing as she passed poker, blackjack, craps and roulette tables.

Then she saw April. Holly froze in shock.

Standing in the back, with a choker on that was clipped to a fine chain, her sister stood behind an elegant woman in a deep blue cocktail dress. The woman held the other end of the leash. April’s body was on full display in a translucent blue baby doll. She looked blank, ignoring everything around her, just like the other collared people.

Holly rushed to her sister, nearly running into several people on the way, and barely keeping all of her chips in the tray.

“April!” she cried as she approached. “April! Oh thank God, it’s you!”

Both April and the woman looked at her.

“Let’s get out of here, April. Go home... Mom and dad...” Holly stuttered and stepped in to give her sister a hug. The woman blocked her.

“I’m sorry, do you know this slave?” said the woman.

Holly’s jaw dropped. Slave? “Uh, what? Who the fuck are you?”

“You may call me Mistress Scarlett. And she is my slave. Do you know her?”

“Your slave?” Holly looked at the woman, then at her sister. “April?”

The woman chuckled. She glanced at April. “You may speak, slave.”

“Holly, I’m her slave. You need to win me back, like I told you,” said her sister.

“That’s enough, slave,” commanded Mistress Scarlett. “So, you are the one she managed to call?”

“What the fuck is going on here?” said Holly.

“My slave managed to call out one day, and apparently she reached you,” replied the woman. “I take it you would like to win her?” She gestured at the tray Holly was holding.

“Why the fuck do I have to win her back? She can leave whenever the fuck she wants to!” said Holly forcefully.

“Slave, would you like to explain?” said Mistress Scarlett.

“Holly, I bet myself and lost. I’m her slave. You need to win me back,” April said, “Please.” She looked forlorn. Holly just stared, nonplussed.

“Follow me,” said the woman. “You better know poker, for your sake.” She tugged on the leash and Holly watched the pair walk towards a room at the side of the floor. As they disappeared through the doorway, Holly shook off her shock at the exchange and hurried to catch up.

The small room had only one table, with a dealer standing at the ready. Mistress Scarlett was sitting at one of the six chairs around it and gestured at another. Holly sat down.

“Texas hold ’em,” said the dealer. “Small blind to the lady in black.”

Holly had played poker before, but she was no expert. “April, do we really need to do this? Let’s just go.”

“You really do,” said Mistress Scarlett, tossing in two chips.

“No fucking way am I doing this,” Holly said. She reached for the April’s chain. The woman held it out of reach, standing quickly and backing towards a door behind her.

“Slave, it appears your sister doesn’t want you back,” she said. “Let’s go play.” Tugging at the leash, she led April away from the table.

“April? April!” said Holly, her voice rising. “What are you doing? Why are you following her?”

“She has to,” responded Mistress Scarlett. “Good day.” One of the two bouncers at the door opened it, and the pair started through.

“Wait! Wait!” shouted Holly.

Mistress Scarlett turned slowly. “Are you willing to play?”

Holly sighed, shoulders slumping. “I... fuck. Yes, let’s play.” She watched the pair turn back, with the woman sitting down and April standing behind her.

Holly sat, blew out a deep breath, and tossed in one. “Aren’t there usually more players?” She gestured at the empty chairs.

“Since you want this slave, it would be best head-to-head, don’t you think? I’ll even match your small stake to give you a chance.” The woman stacked her own fifty chips in front of herself from the thousand or so brought by a casino employee.

The dealer flipped two cards to each of the two women. Holly schooled her features and checked her cards. The jack of clubs and six of hearts. Possibly good enough to play, but not raise. “Stay.” Mistress Scarlett stayed as well.

The dealer flipped out the three cards in the flop. They were a king of hearts, a jack of spades, and a two of clubs. Holly kept her features even. She had the first bet, and tossed out four chips. Mistress Scarlett folded. Holly pulled over her minor winnings, and felt a strange little thrill.

The next hand, Holly got the nine of diamonds and two of clubs. She glanced at her sister and folded, effectively giving the two chips from the last hand back to the woman. Oddly, she still got a thrill, but different, more sexual. Holly got lucky for the third and fourth hands, getting two pair in one and winning five, and getting two aces in the other and winning three. Each time she pulled the chips over, a matching jolt, like the first, hit her, full of confidence and elation. She mentally shook it off, trying to keep her features tightly controlled.

“We’ll be out of here soon,” she said to April, who was standing still and watching the game.

Mistress Scarlett leaned towards her. “You feel it,” she said. “I know you’re attempting to hide it, but I can tell. It’s the thrill of winning here.” She leaned closer. “It’s good, isn’t it? Addictive. Sweet. It’s why I keep coming.” Smiling, she whispered, “But just wait until you lose. Really lose.”

Puzzled, Holly tossed in her chip a little hesitantly. Her hole cards were the ace of spades and king of hearts, definitely a playable hand. The flop showed the ace of hearts, so she was feeling pretty confident, and put in two. The lady called. The turn and river didn’t help, but she still felt pretty good about a pair of aces. The woman hadn’t raised her, so it was entirely likely that she didn’t have much. Holly tossed in two more chips. The woman raised four. Holly sighed, feeling stuck. She was in four, but she had won those, and could drop out still up. It was aces though, with nothing showing on the table. She called.

Mistress Scarlett smiled, flipping over her own ace, and a ten that matched the turn. Holly groaned internally and showed her ace and king. As Mistress Scarlett pulled over the chips, Holly felt another tingling thrill, running straight to her crotch. A moan nearly escaped her parted lips.

“See?” said the woman. “Be careful. You might start to want it.”

Holly shivered a little, knowing exactly what the lady meant. It felt good. She took a deep breath as the next hand was dealt. She had two pair this time, and was in ten chips plus her blind when the woman called. Again Holly lost, this time to three jacks. She sucked in hard as the jolt slicked her pussy and ran up to her chest. Her mind washed in pleasure that made it hard to think, hard to remember why she was here.

“Losing that many of your initial stake at once must have been luscious,” whispered Mistress Scarlett in her ear. “I know you want more of it. Good thing I’m here to give it to you.”

Holly whimpered and tried to focus as the dealer flipped out two cards to each of them. On the small blind, she ended up folding immediately with an off-suit ten and six. The little thrill added to what she was already feeling. She could tell her panties were getting damp.

“It gets better each time, doesn’t it?” said the woman. “Some come here to lose, just to feel it.”

Holly let out a whining moan and shook her head to focus. For the next hand, she had two kings in the hole, and managed to concentrate above the pleasurable fog building in her mind. With a king on the turn, she ran up the bet, matching all she’d lost. When Mistress Scarlett turned over two pair, Holly blew out a deep breath as the confidence thrilled through her. The fog lifted entirely, and she looked at the table clear-headed.

“It won’t be long and we’ll be out of here,” she said, looking up at April.

“Such confidence,” said Mistress Scarlett, grinning at her. It made Holly a little uncomfortable.

They kept playing, with Holly and the woman effectively passing the same few chips back and forth on a bunch of folds. Eventually Holly had a hand with two queens and two jacks, and ended up in sixteen chips. It was the largest bet so far, and when the woman turned over a better two pair hand, aces over jacks, Holly whined as she watched the chips pulled away. Then her mouth dropped slightly open and her eyes rolled up, the jolt stronger than before. It slicked her panties and brought back the pleasant fog. Need coursed through her veins, making her breathing a little labored and her nipples press against her bra.

“There we go,” said Mistress Scarlett. “That’s better. You’re probably enjoying that quite a bit, aren’t you?” She leered at Holly.

“Don’t worry, April, I’ll get it back,” Holly managed through the heat washing through her.

Another few hands went by with folds, until finally Holly got two kings to play. The woman folded on the flop, though, when Holly tried to get some of those sixteen chips back. The slight bits of confidence she got with each small win helped a little, but the fog still permeated her mind.

Her next hole cards were a queen of hearts and a ten of spades. Since Mistress Scarlett stayed, so did she, and the flop gave her hope. It had a king and nine of clubs. The woman stayed, and so did Holly. The turn showed a jack, and Holly’s fogged mind barely managed to keep her features controlled. Not really concentrating but certainly confident in her hand, she said, “All in,” and pushed her chips to the center. The woman called. They each flipped over, and the lady had the ace and king of clubs. Holly’s dazed mind checked the cards again, then checked again, and realized that Mistress Scarlett now had four clubs. She shivered as the river card flipped over.

Two of clubs.

Holly whined aloud, and as Mistress Scarlett started pulling the chips over, she nearly fell off her chair, boneless, as the brilliant thrill filled every part of her. Her pussy melted in need as her mind became lost in pleasure. She couldn’t think beyond the burning desire consuming her being.

“Well now, it appears I’ve won.” The woman smiled at her. Holly could only see the beautiful lips, the lovely brown hair, the soft breasts that the woman had. She wanted to lean in and suckle. “But you do have one more thing to bet with, if you still want your sister.”

Holly, eyes locked on the woman’s chest, barely nodded.

“You can bet yourself, little dear.”

Again, unable to think clearly through the desperate, sexual heat burning through her, Holly nodded.

“Good. Dealer, note the bet.” The woman put in the original stake, fifty chips.

The cards were dealt, and it took Holly all she had to pull her gaze off the flesh around her and down to the two cards. She saw two sixes, but couldn’t really think through if that was good or bad. The flop showed a ten, seven and three, the turn an ace, and the river a jack. Holly turned over her sixes, and watched as the woman flipped over an ace and queen.

Holly could hardly comprehend that she’d lost. She just watched as the woman pulled out a collar.

“Lean towards me,” said Mistress Scarlett. Warmth spread through Holly as she felt the collar click around her throat. “Come along.” The attached leash pulled Holly gently after the woman, a jolt of pleasure at obeying coursing through the college student’s body. The three headed to the door Mistress Scarlett had lead April through earlier. The two burly men both nodded at Mistress Scarlett and again, one opened the door. Holly could hardly notice, and only followed as she had been told. Inside, a dark hallway was dotted with doors. Going to an open one, the woman pulled the two sisters into the room and closed the door.

“Now then, let’s see what I’ve won,” she said. “Strip, both of you.”

Thoughtlessly, Holly pulled off her dress, dropped her bra and slick panties, and stepped out of her shoes. Obeying felt right and sent the same erotic thrill as losing coursing through her. She panted in need as April stood nude next to her.

“I need to find out how good you are, slave.” The woman ran a finger under Holly’s chin. “Eat me out.”

Mistress Scarlett laid back on the bed, pulling up her dress and dropping her panties. Holly disappeared underneath and moved quickly to the woman’s damp pussy. Holly dripped down her thighs as submissive bliss ran up from her crotch to melt her mind.

“Slowly,” Mistress Scarlett said. “Tease me.”

Holly did as she was told, and was rewarded with blistering pleasure. She kissed gently up one thigh while her fingers ran along the other. Softly working her way up, she suckled where the leg met the crotch. She heard a sigh from above her as she used one finger to tenderly play with the velvet folds, but avoided the woman’s clit.

“Better,” sighed Mistress Scarlett. She reached down and grabbed the back of Holly’s head. “Now, get me off.” She pressed Holly into her crotch.

Holly licked from the base of the woman’s pussy to her clit, then gently suckled between her teeth as she thrust two fingers in and crooked up to hit the woman’s g-spot.

“Oh God it gets me so worked up winning someone,” Mistress Scarlett said as Holly continued working. “Suck me, you slut! Oh, fuck!” Seconds later, she ground her crotch into Holly’s face and arched her back as she crested, choking on her own breath. Holly shook in erotic bliss at having obeyed.

Once recovered, Mistress Scarlett shoved Holly back. “I’m so glad I had her call you,” the woman said. “Now, I have a matching set.” She smiled. “Time for you two to play with each other. Kiss,” she said.

Holly and April turned to each other and pressed their lips together, their tongues playing softly.

“Oh, I’m going to enjoy this,” said the woman, smiling.
