Linny had been preparing the studio since before dawn, cranking the heating elements embedded in the bamboo flooring until the thermometer pushed past a hundred. The room was a converted solarium on the eastern edge of the resort, glass walls fogged against the cool Pacific morning, creating a hothouse atmosphere that smelled of cedar and eucalyptus, and the faint, persistent musk of arousal that never quite left those porous bamboo floors.

She wore a sports bra that strained dangerously against her chest, the fabric sheer with sweat before the first student even arrived.

"You really want me to bend myself into a pretzel in that?" Sylvia Harbor stood in the doorway, wearing a silk robe that did little to hide her own transformation. The melonade she had started guzzling was working through her system too, her once-modest bust now straining against the robe's belt, cleavage deep and flushed. She looked at the thermostat and raised an eyebrow. "I'll melt."

"Don't worry," Dina said, slipping past her with a giggle. "If you melt I'll just lick you right up."

Dina had changed even more dramatically since taking up residence in the staff quarters. She wore only a cropped tank top and panties, her nipples hard against the fabric, bells removed in the gym area.

Sylvia hesitated, but the heat seemed to beckon her, a physical pull. She dropped her robe. Beneath it, she was naked, as per the rules that Linny had posted outside. "Fine. But if I pass out, I expect someone to do something indecent to me."

"That's the spirit," Linny purred from the front of the room. She clapped her hands together, the sound sharp in the dense air. "Everyone find a mat! Quick, quick, before the cool air gets in."

The room filled rapidly. Cassidy and Cindy arrived together, the bride and her maid of honor from the weekend's festivities, both intending to enjoy their last full day. There were others: a redhead named Paula who worked in the administrative wing, a guest named Sinclair who'd checked in yesterday and already had the dazed look of the deeply conditioned, and three women that Sylvia had seen around, always together, and who moved with the loose-limbed gait of the well-fucked.

"Welcome to Hot Yoga," Linny announced, her voice cutting through the humidity. She stood on a raised platform in front of a mirror that had fogged over completely, her reflection a blur of curves and sweat. "Today we focus on release. Letting go. Opening ourselves completely to the heat, to the stretch, to sensation."

She demonstrated the first pose, a simple forward fold, and her breasts swung like pendulums beneath her, heavy and hypnotic. The fabric of her bra was soaked through, nipples dark and visible. "Breathe in... and fold. Let your head hang heavy. Let your mind empty."

The class followed her lead. Dina bent easily, touching her palms flat to the floor, her panties riding up to expose the cleft of her ass. Sylvia struggled more, her new breasts creating unfamiliar weight, but she folded too, gasping as the blood rushed to her head.

But Sinclair wasn't looking at Linny.

He was staring at Cassidy and Cindy, positioned directly in front of him. As they folded forward, He could see their respective labia. The glistening seam of their arousal. Their cheeks pulled open by the stretch to reveal their tight rings.

His cock twitched, hardening rapidly. He'd been drinking the Mango Nectar since his waitress gave it to him with breakfast, then in the hydration station, then again in his room. The resort's signature blend was working through his system, flooding his blood with synthetic testosterone and vasodilators, enhancing not just his libido but his physical dimensions. He felt heavy, thick, engorged. And so early in his stay, he wasn't yet used to the impact on his mind.

"Up slowly," Linny instructed, rolling her spine vertebra by vertebra, her breasts bouncing with each movement. "Reach for the sky. Stretch... stretch..."

They moved through sun salutations, the heat building, sweat beginning to pour. Within ten minutes, the room smelled like a sauna. Sinclair's erection was full and throbbing now, bobbing with each pound of his heart.

"Warrior Two," Linny commanded, stepping her feet wide, arms outstretched. "Hold... hold... feel the burn. Let it consume you."

Cassidy and Cindy held the pose, thighs trembling. Cindy leaned forward slightly, adjusting her stance. Sinclair groaned; the sound of a man being consumed. His shaft was veined and thick, the head purple and slick with precum. It stood upright, a bead of clear fluid forming at the slit and dripping onto his mat.

She rotated her hips, demonstrating the next pose, her own arousal evident in the way she moved, the way her nipples had hardened to bullet points. "Wide-legged forward fold. Take it wide. Bend deep. Let everything hang."

The class obeyed. Cassidy and Cindy spread their legs, bending forward, presenting themselves completely. Then Cindy lost her balance, stumbling backward and into Sinclair. He grabbed her, arms wrapping her up to keep her from falling further, and hands gripping tight into her breasts. She moaned at the contact and then again when she felt his massive rod sliding between her sweat-soaked thighs.

That was all it took for him.

The combination of chemicals and arousal and sudden contact with the woman he'd been staring at all session… His cock twitched between her legs and shot a load of cum forward onto the mat in front of her. She and her sister looked down at it, the Cassidy saw the monster that had made it, still hard and twitching beneath her sister.

"Everyone okay back there?" Linny asked, but no one really answered.

Several eyes were now on Sinclair's raging boner as Cindy tried to stand back up, giving everyone a clear view.

"Focus on your breath," Linny tried, but her voice had gone husky. She could see the shift in the room. Paula's her eyes were wide, tongue darting out to wet her lips. The three other women were transfixed as well, their yoga poses forgotten, staring at the thick shaft of meat standing upright in their midst.

"Maybe we should take a water break," Linny suggested weakly, but it was too late.

Cassidy straightened first, her enhanced breasts heaving, sweat running in rivulets down her cleavage.

"He's... he's dripping." Cassidy said, and it was true. Even after his first load, precum was still freely leaking from his cockhead. They couldn't resist. It wasn't a choice. It was chemistry. Cassidy was already moving, crossing the three feet between her mat and Sinclair's, her hips swaying, nipples tight and aching. Cindy followed, her hand still between her legs, fingers sliding beneath the fabric now, stroking herself as she walked. Others came too, drawn by the sight and the scent.

"Look at it," the blonde whispered. "It's so... thick."

"He's been drinking the mango," Cassidy said, her voice thick with understanding. She dropped to her knees, the heat of the floor radiating up through her skin. "I can smell it." She took a scoop of his cum from the floor. "God, I can taste it."

Mark groaned as Cassidy reached out, her fingers wrapping around his shaft. The contact made him buck, a fresh dollop of precum welling up, and Cindy made a desperate noise, falling to her knees beside her sister, leaning in to lick the fluid from the tip.

"Um," Linny tried again, but her hand had gone to her own breast, squeezing hard through the soaked fabric. "Class?"

"Shhh," Sylvia said from the front row. She'd been watching, her new tits heaving. She stood up, abandoning her pose, and walked toward the group. "I want to see him fuck them."

That broke the dam.

The women descended, hands reaching, mouths opening. The blonde took Mark's balls into her mouth, sucking gently, rolling them with her tongue. The brunette positioned herself beneath Cassidy, lifting the bride's hips to access her cunt from behind, licking upward in long, desperate strokes. The pink-haired woman straddled Mark's thigh, grinding her denim-clad cunt against his muscle, her eyes rolling back at the friction.

Cindy had taken Mark's cockhead into her mouth now, her lips stretched wide around his girth, while Cassidy worked his shaft with both hands, stroking upward, milking more precum, which Cindy greedily swallowed.

Linny stood frozen for a moment longer, watching her yoga class dissolve into an orgy, watching Dina crawl across the floor to join the pile, watching Sylvia kneel beside Mark and offer her heavy, newly-grown tits to his mouth. She tried to summon the words to regain control, to guide this back toward structure, toward the resort's careful programming.

But then Mark groaned, a guttural sound of absolute surrender, and Cassidy pulled off his cock with a wet pop, turning to offer it to her sister, and Cindy took it greedily. Hands were in panties, fingers in cunts, and Linny realized she was stroking herself too, her conditioning triggering at the sight of such uninhibited lust.

"Fuck it," Linny muttered, and she left the orgy to finish in her class, walking to the locker rooms on her own.

The heat in the room seemed to spike. Sinclair lay back on his mat, the bamboo hot against his back, and let the women arrange themselves around him, on him, using him. He was hard, he was leaking, and he had never felt so perfectly, completely relaxed in his life. Cassidy impaled herself on his's cock, as Cindy sucked her sister's tit.

Sylvia sat right down on his face without waiting for an invitation, her rapidly inflated chest bouncing and jiggling in wonderful new ways. Sinclair's tongue went to work immediately, causing her body to shudder and tremble and jiggle even more. He came inside of Cindy, and though the mango was keeping him hard, he hadn't had any lemon or banana and his stamina was beginning to wane.

"You have one more in you," a older, black-haired woman said as Cindy climbed off. She wrapped her fingers around his twitching shaft. "Don't you, my good boy?"

He grunted as she climbed on, talking to him soothingly and softly. Telling him that it was okay that he was feeling worn out and sleepy. That these girls had done a number on him. That he deserved a good rest. He just had one more job to do.

She groped Sylvia as she continued to ride his face.

"Isn't that right?" she asked Mrs. Harbor.

Sylvia moaned her agreement.

"No, no," the mysterious woman said. "That won't do. This one needs to be told. He needs us to tell him. Tell him."

"She's right," Sylvia finally said, the hands on her chest and the soft voice pushing her to obey. "You're being such a good boy. Pleasuring both of us. You can do it."

"You can do it," the other woman echoed, hips grinding against him. "Count him down."

"Three," Sylvia said, her own orgasm approaching.

"Two," the other woman said.

"One," the said together. Sylvia gushed down onto his face. Sinclair erupted inside of the black-haired woman. And in turn, she shuddered and moaned, then climbed off. She offered Sylvia a hand up, then leaned down and pulled Sinclair up off the floor. His eyes were half-closed. His cock was finally starting to deflate.

"My good little employee always works best with praise," she said. She grabbed is soft cock and gave it a tug. "Come along Sinc. Let Mummy Josie put you to bed."

"Yes, Mummy," he mumbled as his boss lead him away by his dick. The ladies in the room who hadn't gotten a turn with him watched them go, disappointed.

Elsewhere in the resort gym, Malorie was discovering her own path to obliteration.

When she'd mentioned wanting to "bulk up a bit, maybe get stronger," the handsome attendant had pressed a shaker cup into her hands.

"Protein shake," he'd said. "Special resort blend. Increases strength. Builds muscle. And... helps in other ways, too."

She'd drunk it greedily, the thick vanilla liquid sliding down her throat. She wasn't brand new to the resort. She'd seen what some of the drinks they served could do. She'd been fucked in the sauna, fucked in the bar, fucked in the hallway outside her room. She knew that the shake would likely do something wild to her, but if it also helped her workout, then who cares?

Now, standing before the free weights, Malorie was no longer quite herself. The shake had done exactly what the attendant promised. It had increased her strength, yes, her muscles felt warm and powerful and ready. She stared at the dumbbell in her hand: thirty pounds, curling easily, her bicep swelling with the effort. But she was also trying to remember what car she drove. She was meant to check out tomorrow and suddenly, she didn't remember where she parked. Or when. Or what model is was. What color is was.

She laughed. She was so forgetful, sometimes.

She set the weight down, picked up her shaker cup, and drained the rest of the thick liquid. Immediately, warmth spread through her chest, her hips, her... her thoughts. It was like the shake was a blanket on her mind, keeping is soft and wet and thick. Viscous and full.

She looked down at herself. Her sports bra seemed to itch and constrict. She was so sensitive, her nipples pressing against the material like they wanted to be touched.

"Malorie sexy," she whispered, giggling. "Malorie strong."

"Oh do you think so?" a voice said from behind her. She turned to see a man with massive arms and a wide smile. "Are you strong?"

"Hiiiiiii," Malorie said, the word stretching into three syllables, playful and empty. "I'm like, SO strong." She curled the weight again as proof.

"Bet I'm stronger."

"No way!" she said with a mocking pout.

"Let's make a bet, then. If you can bench more than me, I'll let you suck on this."

He pulled his gym shorts down and a cock flopped out that was eight inches soft. Malorie gasped and nodded her head as fast as she could.

"And if you can't?" he asked. "If I bench more than you?"

Malorie's hand moved to her tits, squeezing them together, presenting them. "Then you get to cum in my ass," she said simply, as if discussing the weather. "That's fair, right? If I'm wrong, you fuck my big round butt."

"Load the bar," the man said simply.

They worked in silence, Malorie's thoughts drifting as she added weight. She thought about how good her shake had tasted. She thought about how sexy she looked in the mirror, all tits and lips and empty eyes. She thought about how big his cock would feel inside her, how it would feel splitting her open, filling her, claiming her. And before she knew it, she wasn't even thinking about sucking it anymore, like winning wasn't even in her mind.

And just like that, her arms wobbled, and the bar tilted, spilling the circular weights and sealing her defeat.

"Oh no," Malorie breathed, but she was smiling. "I lost. I lost the bet."

The man was already standing over her, his shadow falling across her body. "That you did. Turn over."

She scrambled to comply, rolling off the bench, bending over it, presenting her ass. He pulled her shorts down in one rough motion, exposing her; no panties, of course, why would she wear panties?

"Beg," he commanded.

"Please fuck my ass," Malorie whimpered, her pussy dripping, her mind empty of everything but the need to be filled. "It's all Malorie is good for! Malorie is a slut. Malorie is a dumb butt slut!"

She felt him rubbing something cool and slick on her hole, then she felt the head of his now-hard cock rubbing circles around her. She sighed and felt her body relax to let him in. He pushed. She exhaled. And he slid inside.

He was so big. So thick. Her ass stretched around him, burning, aching, perfect. He didn't wait for her to adjust. He began to fuck her with brutal, punishing strokes, each thrust driving the air from her lungs, making her tits swing beneath her, making her fingers scrabble at the bench padding.

"Stupid bimbo," he said, her face rubbing against the bench.

"Stupid bimbo!" she repeated with a euphoric yelp. "Stupid bimbo Malorie lost her stupid bet and now gets stupid fucked!"

Heads turned. Guests and staff alike paused in their workouts to watch, some stroking themselves through their clothes, some simply observing with the detached interest of those who had seen this a hundred times before. At True Tide, public humiliation was just another form of pleasure. Just another way to serve.

The man gripped her hips, his fingers digging into her flesh, and pounded her harder. Malorie's screams became moans became broken whimpers, her body betraying her with pleasure, her empty mind filling with the sensation of being used, being claimed, being broken.

"Going to fill you," he grunted. "Going to pump my cum into your stupid bimbo ass. Is that what you want?"

"Yes," Malorie wailed. "Yes! Please fill Malorie up! She's just a dumb butt slut!"

He came with a roar, his cock pulsing, his seed flooding her, hot and thick and endless. Malorie felt it filling her, and she came too, her pussy clenching on nothing, her ass milking his cock, her mind shattering into pieces that would never quite fit back together the same way.

Meanwhile, in the locker room, Dina stood beneath one of the showerheads, her back arched, water streaming down her transformed body. Linny was on her knees in front of her, the water plastering her black hair to her skull, running in rivers down her enormous, melon-fed breasts. She gripped Dina's hips with both hands and buried her face between Dina's thighs, her tongue finding the clit with the precision of long practice.

"Oh, fuck," Dina gasped, her hands going to Linny's head, fingers tangling in the wet hair. "Right there, yes, yes…"

Sylvia stood under an adjacent shower, watching them, her own body slick with soap. Her new breasts ached as she watched. She'd been trying to wash herself, to scrub away the sweat of the yoga class that had dissolved into an orgy, but her hands kept drifting to her nipples, rolling them, pinching them.

Sylvia's mouth opened. Her eyes glazed. The water ran down her face, into her eyes, but she didn't blink. She was staring at Dina's tits. Even without the bells, they were captivating, the way they swung with Dina's panting breaths, the way they caught the light even in the steam.

"Look at her. She's totally gone," Linny laughed, returning to her task, sucking Dina's clit between her lips, making the bells peal wildly as Dina bucked.

"Good," Dina breathed, looking over at Sylvia with a hazy, triumphant smile. She was staff now. She understood things that guests didn't. "Sylvia. Hey! Syl!"

It took a moment for Sylvia to respond, her pupils wide, her hand frozen on her own breast. "Y-yes?"

"The maid who runs the locker room," Dina said, her voice dropping into the cadence that True Tide had taught her, the rhythm that bypassed conscious thought. "Amy. She's out sick today. Stomach thing. We need someone to cover."

Linny added a finger, sliding it into Dina's cunt, making her gasp and jingle. "We need someone helpful," Linny continued, picking up the thread. "Someone who wants to be useful."

"Useful," Sylvia repeated. The word felt good in her mouth. It felt right. The bells were still ringing, softer now, a background chime that synchronized with her pulse.

"You'd be perfect," Dina said, coming suddenly, her body seizing, the bells shrieking a bright, metallic song that seemed to etch itself into Sylvia's frontal lobe. "Would you like to fill in? Just for today? Help all the dirty guests get clean?"

Sylvia's hand moved down her stomach, finding her own cunt, slick and swollen. She was nodding before she realized it, the decision made somewhere deep and automatic. "Yes," she whispered. "I'd like to be useful."

"Good girl," Linny purred, standing up, her body glistening. She kissed Dina deeply, sharing the taste, then turned to Sylvia, cupping her face, water streaming between them. "Then let's get you ready."

Time became fluid after that.

Sylvia remembered fragments. She stood by the entrance with a stack of warm towels, handing them out with a smile that felt painted on; permanent and glassy. "Welcome," she said, over and over. "Let me help you with that."

A woman with red hair and freckles across her nose - it might have been Paula from the yoga class, or maybe someone else - came in dripping sweat. She didn't speak, just stood in front of Sylvia with her legs slightly spread, her eyes questioning.

Sylvia understood. She placed a towel on the floor and dropped to her knees. Her cunt was swollen, fragrant, leaking cum and arousal. Sylvia licked it clean, methodically, thoroughly, the taste flooding her mouth. The woman came with a soft sigh, patting Sylvia's head like a pet, then wandered toward the showers.

Some time later a couple came in. All the locker rooms at the resort were co-ed. Nothing to hide, after all. Not here.

The man was hard, the woman was laughing, her breasts marked with red handprints. They needed help with the soap. Sylvia followed them into a shower stall and rubbed the lather over their bodies, her hands moving automatically, finding every crevice, every fold. The man bent the woman over and fucked her while Sylvia knelt beside them, holding the soap, ready to wash them again when they finished. When he pulled out, Sylvia cleaned his cock with a soapy cloth, then washed the cum from the woman's thighs with her tongue.

She was useful. She was helpful.

A woman stood in the entrance to the shower area. She was six feet tall at least, with shoulders like a swimmer and thighs like tree trunks, every muscle defined and veined. But her face was blank, mouth slack, eyes wide and unfocused. She was covered in white, drying fluid.

"Melanie," the woman said slowly, the word taking effort.

Sylvia stood up, her training kicking in. "Welcome, Melanie. You look like you need a shower."

Melanie blinked, the processing delay visible. "Cock," she said finally, as if answering a question. "So much... cock. Protein... shakes." She flexed her bicep, the muscle bulging obscenely, but her expression remained that of a confused child. "Make me... strong. But... dumb. So dumb."

"That's alright," Sylvia said softly, taking the woman's hand. She led her to a shower, turning the water on warm. "We have something for that. But first, let's get you clean."

The cum was everywhere, crusting in her pubic hair, pooled in her navel, smeared across her cheeks and lips. She'd been used thoroughly, repeatedly, her enhanced muscles allowing her to endure a marathon session that had left her mind reduced to a single, simple need.

Sylvia started with her face, using a warm washcloth, gentle. Melanie stood placidly, her eyes following Sylvia's movements. "Good?" Sylvia asked.

"Good," Melanie agreed. "You... nice."

"Thank you," Sylvia said. She moved down, washing the shoulders, the breasts. Melanie moaned when Sylvia touched them, a low, guttural sound. The stomach. The hips. And then, the cunt, swollen and red, leaking multiple men's seed. It ran down Melanie's thighs in thick streams, mixed with her own arousal, the scent overpowering. Sylvia didn't hesitate. She'd been told to be helpful. She knelt, the water cascading over her back, and began to lick.

Melanie tasted like salt and vanilla. Sylvia lapped at her, cleaning the cum from her labia, pushing her tongue inside to retrieve more, swallowing it down. Melanie leaned back against the shower wall, her massive muscles tensing and relaxing, her hands coming to rest on Sylvia's head, not guiding, just resting there, heavy and warm.

"More," Melanie whispered, though whether she meant more cleaning or more cock, Sylvia couldn't tell. Either way, she obeyed, licking deeper, finding Melanie's clit and sucking it, drawing out more of the mixed fluids, swallowing them, feeling them warm in her belly.

When Melanie was clean she pushed away from the wall with a grunt. Her eyes had refocused slightly, the single-track mind reasserting itself. "Cock?" she said clearly, looking toward the locker room exit.

"Down the hall," Sylvia said helpfully, pointing. "There are still men in the pool about now."

Melanie stood, but Sylvia stopped her before she could go. "Drink this," she said, motherly tone returning to her voice for a moment. "It'll help bring your smarts back."

Melanie gulped down the flavorless liquid and sighed. Linny had warned Sylvia about the shakes and said that she'd probably need to set at least one person right. Melanie lumbered off, naked, dripping water, her magnificent, stupid body moving with singular purpose. Sylvia watched her go, then returned to her station by the towels, her face still wet with Melanie's juices and the residue of a dozen strangers.

The sun was setting when Sylvia finally stepped out of the locker room, her uniform damp and clinging to her skin. She felt... awake. Aware. The trance of usefulness had lifted slowly, until the night time attendant appeared to relieve her.

She'd spent hours serving. Hours on her knees. Hours with her mouth full of strangers. And now there was only one person she wanted to serve. She wanted her husband. And, unfortunately, she knew right where he'd be.

With her.

The Pacific Lounge was dimly lit, the blue leather glowing softly under recessed lights. Sylvia walked in, her mesh top still slightly damp, her nipples visible and hard, and stopped. There, in that same alcoves, was Jacob.

He was reclining on blue cushions, his shirt unbuttoned, his eyes glassy and wide. Standing over him was Sasha, the dark-skinned woman from the night before, the one who'd made him admit her dominance over him. She was wearing a silk robe, open in the front, her body lean and perfect, her hand moving in slow circles in front of Jacob's face.

"Watch the light on my titties," Sasha was saying, her voice a purr. "Watch it dance. You want to dance with it, don't you, Jacob? You want to follow it down, down, down..."

Jacob's head lolled. His mouth was open. His cock was out, hard and straining, and Sasha's other hand was stroking it, slowly, rhythmically, matching the circles she traced in the air.

"Melon essence," Sylvia said to the bartender, not taking her eyes off her husband. Her voice sounded strange in her ears, thick with the day's activities. "Please."

The bartender smiled and poured. Sylvia drank it down in one gulp, feeling it hit her stomach, feeling the warmth spread immediately to her cunt, to her nipples, to her brain.

From here, she could see everything: the way Jacob's eyes had rolled back, the way Sasha was now straddling him, the way her husband's hands had come up to grip Sasha's hips, not to push her away, but to pull her down. Sylvia ordered another.

"That's it," Sasha cooed, sinking onto his cock, her robe falling open completely. "Give in to it. Give in to me. Your wife doesn't matter. Only this matters. Only pleasure."

A third shot.

"Fuck you," Sylvia whispered to herself, her fingers circling her clit. "You should be fucking me, you pig."

Jacob groaned, loud enough to carry across the lounge, and Sasha laughed, a rich, triumphant sound, riding him harder, her breasts bouncing, her hypnotic circles forgotten now that he was fully hers, fully entranced.

Sylvia groped at her swelling chest, and ordered round four as she watched her husband breed another woman fifty feet away.
