John watched through a one-way mirror as the yoga class began. It hadn't been easy convincing Emma the cost of private lessons was worth it. In the end, flattery had proved the key—she'd caved once John told her she was too advanced for group sessions and her classmates were holding her back. John shook his head, remembering how Emma's blue, almond-shaped eyes had lit up with the compliment, her full lips curving up into a radiant smile. Emma was an Instagram "model," and she had an ego the size of an ocean. She loved hearing she was better than every one else.

John gazed through the mirror as Emma and her instructor, a lithe, 24-year-old Latina named Sophia, assumed the downward dog position. John shook his head again. As much as he hated to admit it, sitting there staring at Emma's toned ass through her black yoga pants, he had to concede she really was better than most everyone else, at least when it came to her physical appearance. At 5"9' Emma was tall for a woman. She had straight, shoulder-length blonde hair that was pulled back into a ponytail for today's lesson. Her pink spandex top left her midriff exposed and accentuated her thin waist and sizable breasts.

John watched as Emma and Sophia moved into a puppy dog pose. Emma dropped down onto her knees, then leaned forward, stretching her ams out in front of her on her yoga mat. She arched her back, pressing her face and chest into the mat while keeping her ass raised high in the air.

John licked his lips. It he didn't know better, he might have thought Emma was presenting herself to him, asking to be fucked. But of course she wasn't. She thought she was alone with her instructor, and she had no idea John was leering at her form behind the mirror.

John doubted Emma would approve of him watching her private lesson, even though she made a living posing in skimpy clothes for thousands of strangers on the internet. He smiled. Fortunately for him, Emma wouldn't hold a grudge.

John reached forward and hit a small, red button on the panel in front of him, and colorless, odorless gas began spilling into the yoga studio.

The effects began subtly. John watched as Emma and Sophie performed a series of stretches. After around five minutes, John could see Emma's stone-faced determination begin to fade as the gas dulled her thoughts and induced feelings of euphoria. Emma's eyes became unfocused, and her full, pink lips curled up in a blissful, mindless grin.

As the women continued stretching, their form grew increasingly sloppy as their muscles involuntarily relaxed.

John leaned forward for a better look as the women entered the happy baby pose. Emma lay with her back flat against her mat and grabbed her ankles with both hands, pulling her legs back toward her chest. John enjoyed the view of her camel toe through her yoga pants.

As the gas's effects reached their peak, John watched Emma's mouth fall open, her jaw going slack. A thin line of drool escaped her lips and slid down the side of her cheek. Emma let her right leg slip out of her hand as she stared up at the ceiling with vacant eyes. She slowly slid her free hand into her yoga pants and began gently rubbing her clit. In its more advance stages, the gas caused extreme sexual arousal in addition intense euphoria.

John smiled, satisfied. That was the sign he'd been watching for. Emma's mind was now blank and pliable. She no longer had any real understanding of where she was or what she was doing. She was masturbating on pure instinct in response to her sudden arousal.

Sophia lay flat on her back in front of Emma. She'd let go of both legs and was using her hands to massage her breasts through her shirt. John could't hear her through the glass, but he could see her lips mouthing something over again.

This wasn't Sophia's first time under the influence of the gas. Far from it. John had thoroughly conditioned her mind to associate the euphoria from the gas with subservience to him. In fact, John had taken her conditioning so far that she followed his orders even without the gas. But this moment wasn't about Sophia. He was here to play with a new toy.

John pressed the little, red button again, shutting off the gas. He then exited the secret room and walked around to yoga studio. As he entered, he heard Sophia reciting her mantra: "I belong to Master. I belong to Master..." He'd always found her Spanish accent sexy.

John walked to Emma and stood over her. Her eyes stared up at John, but it was clear from her vacant expression that she didn't see him. She still held her left ankle in her hand, but her right leg lay splayed out on the floor, and John could see a bulge in her yoga pants where her right hand was playing with her pussy.

"Hello, Emma," John said, smiling broadly. "I'm a big admirer of your modeling work. I think you'll soon be an admirer of me as well."

Emma showed no sign she'd heard John.

"Emma, you're going to answer all of my questions truthfully and follow all of my orders obediently," John instructed. "As long as you do exactly what I say, you'll keep feeling this good. You do feel good don't you?"

"Yesss," Emma whimpered, her voice wavering from pleasure. "Feel good..." Her eyes remained blank, and her jaw went slack again as soon as she'd finished answering.

"Good, good," John encouraged. "A sexy girl like you deserves to feel good. Stand up for me so I can get a better look at you."

Emma slowly removed her hand from her pants and let go of her leg. She sat up, then used one arm up help push herself up on to her feet, where she stood slack jawed before John, staring into space.

"I've waited quite a while for this, Emma," John began. "Ever since you joined the studio and I found the slutty pictures you post on Instagram. Tell me, does it turn you on to show off your body online?"

"Yes," Emma replied expressionlessly.

"I figured," John chuckled. "Have you ever taken nude pictures?"

"Yes. I have a paid Snapchat account I use to send nudes," Emma answered.

John nodded. He'd expected as much. It was so easy for attractive girls to make some extra cash these days. "I'm sure your Snapchat followers love that. Luckily for me, I'm going to get a bit more personal experience with you."

John stepped in close to Emma, his face inches from hers. He looked into her eyes vacant as she stared straight through him. He reached up and ran his hand through her golden blonde hair, then then gently ran his index finger over Emma's soft, supple lips.

John pulled his hand away and inspected his finger. Lip gloss. Even for a private lesson, she couldn't resist dressing up a bit. John wiped his finger off on Emma's cheek. "Feeling a little slutty today are we?" he teased.

"No," Emma answered, unaware it had been a rhetorical question.

John frowned. "You'll fee slutty soon enough. Open your mouth," he ordered.

Emma silently parted her lips, and John slipped his finger inside. "Suck," he commanded.

Emma closed her soft lips, and her cheeks sunk inward as she dutifully formed suction around John's finger as it she was trying to drink through a straw.

John sighed. Women tended to take orders a bit too literally under the influence of the gas. "Pretend you're giving my finger a blowjob," he clarified.

Emma's performance immediately improved. She began gently bobbing her head back and forth, sliding her wet lips along John's finger. Insider Emma's mouth, John could feel her tongue skillfully twirling over his skin. Yet her face remained completely blank.

John grinned. Emma knew what she was doing. It was hardly surprising. She had a body built to fuck. She could probably pick up any man she wanted with just a smile.

"Stop," John commanded, and Emma immediately quit moving. John slipped his finger out from between her lips, leaving them slightly parted. "Remove your shirt," he ordered.

Emma slowly reached down and grabbed the bottom of her pink spandex top, then pulled it up over her head, revealing a matching pink sports bra.

"Now the bra," John continued, his eyes locked on Emma's chest in anticipation.

Without hesitation, Emma slipped her arms through the bra straps and pulled it up over her head. John beamed. Her tits were stunning—everything he'd hoped for. He guessed they were C-cups... and he'd gotten pretty good at guessing. Despite their size, Emma's breasts were round and perky. Her rosy pink nipples, firm from arousal, stood out against her smooth, pale skin.

John realized his own jaw was hanging open and he snapped his mouth shut, regaining composure. It was rare he found himself flustered these days, but Emma really was that hot.

"Now take off you shoes and pants," John continued.

Without looking down, Emma slipped off her tennis shoes. She then hooked her thumbs inside the waist of her yoga pants and slid them down her long, perfectly smooth legs, bending forward to reach her feet. Her breasts hung enticingly in front of her, and John found himself captivated.

Once the yoga pants reached the floor, Emma stood back up straight and stepped out of them. She stood facing John again, staring ahead blankly, wearing only a pair of black panties and pink ankle socks.

John grinned. He was enjoying this even more than he'd expected.

"Take off the rest of your clothes," he ordered.

Emma bent over again, her breasts swinging freely, and removed her socks. While still bent at the waist, she reached back and hooked her thumbs under her panties and slid them down to her feet. After stepping out of the panties, she stood back up and resume staring forward into space.

John had played with a lot of women. A lot. Emma was easily one of the most attractive, and that was saying something. He stood admiring how the curves of her hips flowed seamlessly up to her thin waist and down to her long , well-toned legs. He was pleased to see her pussy was clean shaven. No doubt she kept tidy for a boyfriend, but that didn't concern John.

As John stood admiring his newest plaything, Emma's hand drifted slowly down to her pussy, where she resumed gently rubbing her clit. The aphrodisiac effects of the gas were still in full force. John watched her fingers glide along her now glistening pussy for a moment before looking back up at Emma's face, which was still blank. Another line of drool had escaped her parted lips and dripped down onto her tits.

"Stop masturbating," John ordered. Emma would get sexual release, but it would come from him.

Emma let her hand fall limp at her side.

"Turn around, bend as your waist, and grab you ankles," John commanded.

Emma did as ordered, spinning around to face away from John, then bending down to grab her ankles, presenting her ass to John.

"Amazing," John whispered. It was plain from Emma's firm, round ass that squats were a regular part of her workout routine.

John couldn't keep his hands off Emma any longer. He stepped up behind her and cupped her ass cheeks, one in each hand. He squeezed, massaging Emma's ass and enjoying the feeling of her skin against his hands. Then he drew his right hand back and slapped her hard across her right ass cheek. There was a loud slap, and Emma rocked slightly forward, but kept her balance. John admired the red handprint left he'd left behind. "You're so ungrateful. Thank me for awaking you," he instructed.

"Thank you for spanking me," Emma parroted.

John reached down between Emma's legs and ran his fingers along her wet pussy. "Looks like you're ready for some fun," he teased.

John walked around in front of Emma. "Kneel," he commanded.

Emma let go of her ankles and stood up straight before dropping down on to her knees. Her glazed eyes stared straight ahead at John's crotch. Her mind remains thoroughly enthralled by the gas, and saliva continued to drip from her parted lips onto her naked body. John knew her brain was thoroughly flooded with dopamine, and she was experiencing the greatest pleasure she'd ever known despite lacking the mental capacity to understand what was happening to her.

"Listen to me very closely Emma," John instructed in a clam, soothing voice. "You would do anything to keep feeling this good."

Emma nodded slowly in agreement.

"I make you feel this good, so you'll do anything I command," John continued, and Emma nodded in approval.

"When a person follows someone else's commands, that makes the person a slave," John explained. "And the person giving the commands is the slave's master. You are a slave. I am your master."

Emma continued nodding along. Her dazed grin confirmed for John she continued basking in the pleasure of the gas.

"There's nothing wrong with being a slave," John encouraged. "It makes you happy, gives your life meaning. Tell me you agree, Emma. Say 'Yes, Master.'"

"Yes, Master," Emma answered.

"Tell me you would do anything for me," John continued.

"I would do anything for you, Master," Emma answered obediently before slipping back into her mindless grin.

"Good, good," John praised as he unbuckled his belt.

Once John had stripped naked, he turned his attention back to Emma. "Emma," John instructed, "in a moment I'm going to say the word 'begin.' When I do, you're going to give me a blowjob. While you're giving me a blowjob, the pleasure you feel will increase. That's because you're my slave and giving me pleasure is fulfilling your purpose. The more pleasure you give me, the more pleasure you feel yourself. You'll try the please me as best you can, so you can feel more pleasure yourself. Do you understand?"

"Yes, Master,"Emma replied, a hint of anticipation creeping into her voice. While her mind remained so clouded she had trouble forming even the simplest thoughts, John's words broke through the fog by offering the one thing her brain craved: more pleasure.

"Begin," John ordered, clasping his hands behind his head and staring down at Emma.

Emma reached out with one hand and grasped the shaft of John's already hard cock. Then, she leaned it and kissed the tip. The moment her lips touched John's cock she recoiled and gasped. Pleasure flooded her already addled brain, more pleasure than she could have imagined. She came hard, but the feeling of her orgasm was overshadowed by the intense wave of pleasure that came from following John's command. After a brief moment of heavy panting, Emma regained her composure enough to resume her task. She leaned back in and took the head of John's cock into her mouth, letting out a deep moan as her own pleasure intensified.

John sighed. He closed his eyes, taking in the feeling of Emma's soft, wet lips beginning to slide up and down the length of his cock. He felt her tongue start to slide along the bottom of his shaft, and Emma's body abruptly dropped an inch or two as her legs went weak. She knew what men liked, and thanks to John's instructions, her own pleasure was linked to John's. Anything she did to enhance John's experience brought her own ecstasy to new heights.

John opened his eyes again and stared adoringly down at Emma as she bobbed up and down on his cock, her ponytail swaying back and forth behind her head. "Look up," John instructed. "Look me in the eyes while you suck my cock."

Emma looked up. Her blue eyes, normally full of life and energy, looked flat. She was lost in her own bliss. She dutifully followed John's command to look into his eyes, but she didn't really see John.

"Tell me you love sucking my cock, Emma," John ordered.

Emma, still gripping John's cock in her hand and looking up into his eyes, slid her lips off his dick and replied, "I love sucking your cock, Master." She then leaned back in and resumed her work. As her lips touched his dick, Joh watched Emma's eyes roll up into her head momentarily as pleasure overwhelmed her. Once she regained her composure, she resumed obediently staring up at him.

John stood there enjoying the feeling for another minute before deciding it was time to take things to the next level. "Emma," he began, "stop sucking my cock. Bring me you phone and unlock it for me."

Emma again let her lips, now glistening with saliva, slid off John's cock. She stood up, walked to her gym bag, and retrieved her phone. She unlocked it with her fingerprint then walked back to John, handed it to him, and stood motionlessly before him.

John took the phone and opened Snapchat, then typed a message to Emma's followers: "Hey fans! I'm starting a cam show in two minutes. Come join me! I promise you'll see more than you ever have before." John finished the message with a kiss emoji and an eggplant emoji, along with a link to a live cam site. He'd already set up an account for Emma using the information she'd provided when she joined the yoga studio.

"We're going to put on a little show for you fans," John told Emma cheerfully. "Tell me, have you ever sent your followers a nude picture or video showing your face?"

"No, Master," Emma replied.

"Have you ever had sex or masturbated on camera?" John asked.

"No, Master," Emma answered.

"Well then, your fans are in for a real treat!" John chuckled.

"Sophia!" John said, turning his attention to the gorgeous, Latina yoga instructor still laying on the floor mindlessly reciting her mantra. "Come here."

Sophia stopped reciting her devotion to John and stood, then approached John. John logged in to the cam site on his phone then handed it to Sophia. "When I say 'start the show,' hit the 'broadcast' button and film Emma and me," John instructed. "Keep my face out of frame at all times. Keep as much of Emma in frame as you can. Do you understand?"

"Yes, Master," Sophia answered neutrally.

"Emma," John continued, "when Sophia starts filming, I want you to look at the camera, smile, and greet your fans in a cheerful voice. Tell them you'll be fucking your master today and you hope they enjoy the show. Then I want you to get on your knees and go back to blowing me. You'll follow any instructions I give. Understood?"

"Yes, Master," Emma answered.

"Good," John stated. "Let's get started then. Sophia, start the show."

Without hesitation, Emma gave the camera a big smile. "Hi fans!" she exclaimed cheerfully. I'm going to be fucking my master today. Hope you enjoy the show!"

Emma obediently dropped onto her knees in front of John as Sophia carefully followed her with the camera. Emma quickly picked up where she'd left off, bobbing her head up and down on John's cock. John took pleasure in having Emma debase herself in front of an audience that was no doubt very jealous of him.

"Tell you fans your mouth was made to suck your master's cock," John ordered.

Emma let John's cock slip out of her mouth, then looked into the camera with a lazy smile and glazed eyes. "My mouth was made to suck my master's cock," she declared, then went back to work.

"Good girl," John praised. "Now take my cock as deep into your throat has you can and hold it there until I tell you to stop."

Without hesitation, Emma slid her lips down John's dick until he could feel the head pressing into her tight, warm throat. Emma gagged, and John savored the feeling of her muscles contracting around him. Dutifully, Emma held her head in place. John watched as her eyes began to water, then tears streamed down her cheeks. Still, she stared up at John wearing the same look of drug-addled euphoria.

After a full minute, John ordered Emma to stop, and she pulled back, gasping for air. "Now," John instructed, tell your fans you're a slut who does anything your master commands."

Emma looked back to the camera with her tear-streaked face and parroted John, "I'm a slut who does anything my master commands." There was no emotion in her voice. She was simply stating a fact—a fact she believed because her master told her it was true.

"Get on your hands and knees on your yoga mat," John commanded, and Emma complied. Sophia knelt in front of Emma, ensuring her face stayed in frame. Emma's unfocused, stare passed right through Sophia.
John knelt behind Emma and admired her toned ass and legs. "Tell your fans you pussy belongs to me," he ordered.

"My pussy belongs to Master," Emma echoed, the same stupid grin on her face.

"Tell them you're just a toy, for me to play with," John continued, reaching down and sliding two fingers into Emma's pussy.

"Mmmmm," Emma moaned at John's touch. "I'm just a toy for Master to play with," she agreed, accepting what John told her as true.

"Tell them your perfect body is my property," John went on, his fingers still sliding easily in and out of Emma.

"My perfect body is Master's property," she repeated.

John slipped his fingers out of Emma and lined his cock up with her dripping wet pussy. "Describe for your fans what's happening," he ordered.

"Master's cock is pressing up against my pussy lips," Emma told the camera. "Now it's... mmmm..." Emma's eyes rolled up and her jaw fell open as pleasure consumed her. She knew John was enjoying himself, which heightened her own arousal. "Now Master's cock is inside me," she continued. "Filling me up. It's sliding in and out. Master is fucking me."

"That's enough," John interrupted as he savored the feeling of Emma's warm, slick pussy enveloping his dick. He could feel her muscles tighten around him each time her arousal peaked.

John reached forward and grabbed Emma's ponytail then pulled back, forcing her head up. He felt her pussy tighten around his dick, and John realized Emma must know from personal experience how much men enjoyed being rough with her.

"Beg for me to cum inside you," John ordered.

"Please, Master," Emma began. Despite her clouded mind, there was a hint of eagerness in her voice, even desperation. She knew what she'd feel when John came. Pleasure. Pleasure beyond anything she'd felt so far. Her mind craved it.

"Please cum inside me, Master. Please cum inside you slave."

John pulled back hard on Emma's ponytail as she gasped. Her ample tits bounced vigorously back and forth beneath her, as John picked up his pace and thrust roughly into Emma with conviction.

John felt himself on the edge or orgasm. He let go of Emma's ponytail and grabbed her by the hips, pulling her back into each thrust. He came hard, filling Emmas pussy as he continued pounding into her, his body slapping against her ass.

Emma's shivered and John felt her go limp. The front of her body collapsed down onto the floor. John's grip on her hips was the only thing keeping her on her knees. He could hear her ragged breathing as she struggled to take in enough air.

When his orgasm subsided, John let go of Emma's hips and pushed her ass forward with both hands. She collapsed in a pile on the floor.

"Get a good view of her face, Sophia," John ordered, and Sophia moved around to get a closeup of Emm's face laying against the floor.

"Tell your fans how you feel, Emma," John commanded.

Emma tried to speak between deep breaths. "I... I... It's..."

John chuckled. He knew Emma's brain could barely function right now. Her mind was floating in an ocean of ecstasy. All that mattered was the feeling.

"That's enough, Sophia." John instructed. "Turn off the camera."

Sophia tapped a button to stop recording, then looked at John expectantly with her glazed eyes. John had trainer her well enough that she expected a reward for her obedience.

"Cum Sophia," John allowed.

Sophia's eyes rolled up into her head and she let the phone fall to the floor. She dropped to her knees as her legs went weak and she basked in waves of pleasure washing over her.

John grabbed the phone and and smiled. Emma has made nearly $500 in tips during their show, which was deposited into his own bank account. Not bad considering he'd given her fans so little notice. He opened Snapchat back up and sent another text message to her followers: "Hope you enjoyed the show! Same time next week!" John was confident he'd earn significantly more next time.

"Good girls," John praised, turning his attention back to Sophia and Emma. "Sophia, clean the cum from Emma's pussy with your tongue."

John watched as Sophia crawled on her hands and knees to Emma's limp body. She rolled Emma onto her back and spread her legs, then lay chest down between Emma's legs and began eating her out. Emma showed no sign she was aware of Sophia. She'd given up trying to follow John's last command and lay still, her vacant eyes staring up at the ceiling and her mouth agape.

John watched Sophia work as he got dressed.

When Sophia finished licking up John's cum, she simply lay idle on the floor, her face inches from Emma's pussy.

"Put your yoga cloths back on Emma," John instructed. "Sophia, once Emma is dressed, lead her through the rest of her yoga class. Emma, you follow Sophia's instructions."

It would take about an hour for the girls to finish the class, enough time for the gas to wear off.

"When the class is over, you'll both feel extremely relaxed and content. You won't remember anything that happened after I entered the room. Emma you'll feel compelled to return to yoga sessions with Sophia twice per week.

The gas had a strange effect on the brain. Those exposed to it would feel an overwhelming, but subconscious urge to carry out any suggestions given while still under the influence of the gas. While John didn't fully understand the science behind it, the general idea was that the gas triggered the brain's pleasure centers so thoroughly that, even long after the gas wore off, the brain sought to regain feeling. The subject carried out the orders with the subconscious hope it would bring back the overwhelming pleasure.

With multiple exposures to the gas, the brain's subconscious addiction could grow strong enough that the subject would even comply with orders given without the gas. They simply accepted the need to obey whoever gave them the pleasure. Sophia, for example, had been exposed enough times that her mind was putty in John's hands with or without the gas.

John had now laid the groundwork to being the same process with Emma. There was more work to be done, but with time, John would have her following even the most degrading orders without the aid of the gas, although she'd never fully understand why.

"Sophia," John said, getting her attention. "Have dinner ready by seven. I want you naked and kneeling under the dining table like usual."

"Yes, Master," Sophia answered.

Satisfied with his work, John left. There were a group yoga session in the room next door and it was time to scout for new talent.
