The True Tide fitness center occupied the resort's lower level, carved directly into the coastal cliff face so that floor-to-ceiling windows looked out onto the Pacific from beneath the waterline. The effect was disorienting: swimming fish and swaying kelp visible beyond the glass, as if the gym existed in some liminal space.

Chloe and Kenzie arrived at the spin studio ten minutes early, as they always did. The sisters moved with the synchronized grace of shared genetics and shared purpose, blonde and brunette, both wearing only sports bras and the sheer mesh shorts that passed for resort-appropriate bottomwear. Their nipples were already hard beneath the moisture-wicking fabric, anticipating what was to come.

"Third row today?" Kenzie asked, her dark hair pulled back in a severe ponytail that emphasized the elegant line of her throat.

"Second," Chloe countered, her blue eyes gleaming with mischief. "I want to be close enough to smell him."

The studio held twenty stationary bikes arranged in curved rows facing a raised platform. But these were no ordinary cycles. Each seat had been modified, fitted with a thick black dildo that jutted upward at a precise angle: eight inches of silicone molded from life, flared at the base where it locked into the seat post. 

Veined and ridged and obscene.

Chloe was the first to strip, pushing her mesh shorts down her toned legs and stepping out of them entirely. She was bare beneath, her pussy waxed smooth, already glistening with arousal. She approached her chosen bike and positioned herself above the waiting phallus.

Kenzie had stripped too, her tanner complexion flushed with excitement. She mounted her own bike, adjacent to her sister's. They stood there, the tip of that massive cock grazing their entrances, waiting for the instruction to sit and begin.

People trickled in over the next few minutes. Including Dina, you arrived just in time for the class, flushed from the walk through the garden maze. She wore a white tennis skirt and matching top, her dark hair loose around her shoulders, her eyes still carrying the glazed satisfaction of whatever morning programming she'd received. She paused in the doorway, taking in the scene.

"Is this... the spin class?" she asked, her voice uncertain.

Chloe turned, her face radiant with pleasure, the dildo clearly visible beneath her eager cunt. "Yes! First time? You can come sit with us if you like. There's space next to me."

Dina approached tentatively, her eyes fixed on the black phallus jutting from the seat Chloe indicated. "I don't... I didn't realize..."

"It's part of the workout," Kenzie explained, her hips making small, involuntary circles, teasing herself against the silicone. "Corey says it engages the core. The pelvic floor. It's... it's really effective."

Chloe reached out, taking Dina's hand, guiding it to the dildo. "Feel it," she coaxed. "It's soft but firm. It gives, but it fills. And once the music starts... once Corey starts talking... you'll want it, girl. You'll need it."

"Greg isn't... I mean… I'm not sure I'm ready for something that size."

"You know Greg?" Kenzie asked, smiling. 

"My husband." Her eyes were so wide as her hand unconsciously stroked up and down on the black mold.

The sisters shared a look.

"Well then you definitely have to join us. It's fate."

The touch of the silicone seemed to decide her. Dina's fingers traced the veins, the realistic texture, and her pupils dilated. She pushed her skirt down, stepped out of her panties, and positioned herself above the waiting cock.

"That's it," Kenzie encouraged. "But don't sit yet. We have to wait. We must be told when to begin."

Dina nodded. The class had an instructor. The students needed instruction. And so she stood, a nervous mirror of the sisters beside her. A foot on each pedal and a heat waiting for her below.

The lights dimmed. The music began. But it wasn't the ambient tones of the resort's public space. It was something harder, more insistent. A driving bass beat that matched the rhythm of sex, of thrusting, of bodies moving in desperate union. 

Corey emerged from the shadows, and Chloe felt her cunt clench involuntarily around the dildo.

He was magnificent; six-foot-two, dark skin gleaming with oil, wearing only compression shorts that did nothing to hide the substantial bulge of his actual cock, the real flesh that the dildos modeled so precisely. His smile was white and sharp and knowing.

The screen behind and slightly above him displayed a large blue and green spiral in the same colors as the True Tide logo.

"Welcome to True Tide Spin," he said, his voice amplified, resonating in Dina's bones. "Today we're going to work out all that tension. All that resistance. We're going to ride hard, and we're going to ride deep."

He mounted his own bike on the platform, but his seat was unmodified.

"Begin pedaling," he commanded.

Dina's legs moved automatically, her feet finding the straps, her body falling into the rhythm. Up and down, up and down, the dildo sliding in and out of her cunt, pistoning with mechanical precision. The angle was perfect. Each downward stroke hit her G-spot, each upward stroke dragged against her clit. She was being fucked by the bike, fucked by Corey's proxy cock, and the spirals on the screen behind him were spinning, spinning, pulling her consciousness into their golden center.

"Spin is about motion and control. The spiral never stops. It goes around and around forever, just like the pedals on your bikes. What does that mean?"

A chorus of voices rose up from those guests who had attended before. "Our motion is spiral motion, sir!"

Dina's pussy clenched around the tip of the silicone cock listening to how well everyone was programmed. 

"The spiral always pulls you deeper, just as you are pulling me deeper into yourselves with each revolution. What does that mean?"

"Our motion is deeper motion, sir!"

"And if you watch it long enough, the spiral takes control of your minds, just as I control the class. What does that mean?"

"Our motion controls us, sir!"

"That's right," Corey's voice flowed over them, warm and rich and irresistible. "Feel it moving inside you. Feel how full you are. How complete. The bike is fucking you, and you're letting it happen. You're begging for it. You're riding that cock like good little sluts."

Dina was dimly aware of Chloe and Kenzie beside her, the sisters' breath coming in ragged gasps. Kenzie was slamming down harder and harder, taking more of the full eight inches with each stroke, her arousal making obscene wet sounds as the dildo plundered her. Dina was still struggling, still hovering above the seat, taking only six inches, then six and a half, her face twisted with desperate effort.

"As an extra treat," Corey said as he pedaled in front of them, "If you can prove to me with my models that you can handle me, I'll give you the real thing. I'll take you back to my room and fuck you with the original. Do you want that, girls?"

The class moaned in unison, a chorus of need. Chloe pedaled harder, her thighs burning, her cunt clutching, her mind dissolving into the spiral patterns on the screen, into the pulsing bass, into Corey's hypnotic voice.

"Kenzie can do it," Corey observed, his eyes fixed on the brunette. "Look at her. She's so close. Come on girl. Just a little more."

Kenzie's eyes were white, rolled back until there was no more visible color. Her body moved in a frenzy of desperation until her thighs made contact with the leather seat, black cock sunk to the hilt inside her.

"She's ready for the real thing. Are you ready, Kenzie? Are you ready to be fucked by your instructor?"

"Yes!!" Kenzie gasped, her body convulsing, her hips slamming down one final time. "Yes, please, please, I'm ready!!"

She came with a scream that echoed off the cliff walls, her cunt spasming around the silicone cock, her juices flooding the seat, dripping down in thick rivulets. She kept pedaling through the orgasm, her body moving automatically, milking the dildo, her eyes rolled back, her mouth open in silent pleading.

Corey smiled. "Good girl. But don't think you're done with your workout. And don't the rest of your think that Kenzie is the only one who can win. Keep going."

Over the next twenty minutes, four other women in the class managed to reach the seat. As the session ended, Chloe cursed to herself. She looked at Dina.

"Another ten minutes and I'd have fucking had it."

Dina blushed, knowing that she's never have gotten there. At least not today. But she'd certainly be back to try again.

"Go have fun, sis," Chloe said to Kenzie as the woman stumbled toward Corey. Her eyes were still fixed on the spiral, glassy and empty, and she gave no response to her sister as she left the room following the instructor.

"She gets to have all the fun. Well except when we were in the sauna. Greg picked me to fuck and Kenzie had to watch."

"Greg?" Dina asked, finally coming all the way out of her stupor.

"Oh yeah. He fucked me really good. Had some of that banana stuff that makes you cum like crazy. You should have seen it."

Dina moaned.

"Let's shower," Chloe said suddenly. "Your room. I want to tell Greg that you and I met."

Dina nodded shakily, lifting herself off the dildo with a whimper. Her cunt was gaping, pink and swollen and empty, dripping with evidence of her attempted submission. "Okay."

They quickly pulled on the clothes they'd stripped out of for the workout and headed to the elevators. Inside, there was a younger-looking girl sucking on the cock of a middle-aged man.

"I don't know how I'm ever going to leave," he said, fingers tangled in her red hair. "Her mother is never going to let her and I do this at home."

Chloe held Dina's hand as the pair walked toward Greg and Dina's room. Key swiped. Door clicked open and closed. And Greg was sitting on the bed, stroking his cock with a far-off look in his eyes, like he wasn't even really aware it was happening.

"Greg," Dina said softly.

His eyes cleared, focusing on them, his wife and Chloe, the blonde sister from the sauna.

"Chloe," Greg breathed, recognition and lust warring in his expression. "What are you doing here?"

Chloe lit up.

"Oh good! You remember me!"

"Uh…," Greg muttered, watching his wife take her top off behind Chloe. Her melon-enhanced tits spilled into view and she smiled. "Yeah how could I forget?"

"We're here to shower," Dina said, reaching forward and pulling Chloe's top off as well, causing the blonde to giggle furiously. Dina fondled Chloe's exposed chest, causing Greg's eyes to follow the round motion. "We had quite a workout."

"Some of us had more of a workout than others," Chloe chuckled.

"It's not my fault Greg's cock isn't as big as that monster on the bike."

Greg's face turned bright red. "What?" he stammered.

"Greg you should have seen it," Dina said, nuzzling her face into Chloe's neck, sending goosebumps across Chloe's skin. "The bikes all had dildos on them and god they were huge. So much bigger than you."

Greg grunted something that might have been embarrassment, but might have been arousal.

"And I got my cunt on it better than her," Chloe said, eyes closed as she continued to be groped and fondled. 

"But you still lost to Kenzie," Dina said with a sly smile. "And now she's getting the real thing stuffed into her holes."

"Fucking slut," Chloe groaned. "Fuck."

Greg just sat there watching, eyes wide and cock throbbing.

"Anyway," Dina said, finally letting her hands fall to her sides. "Like I said, we're just here to shower."

"Oh." Disappointment erupted inside of Greg.

"I'm sorry, honey," his wife said, ushering the blonde into the bathroom. The water started inside and Chloe's shorts shot through the door as she giggled. "But I'm afraid you just wouldn't measure up so soon after having that monster inside me. You understand. It's important that I get the most pleasure that I can."

"It's important you get pleasure," Greg repeated, as his wife disappeared into the bathroom as well. Disappointment and humiliation turned into arousal at the idea of water cascading across their bodies. Maybe they'd let him watch. Maybe they'd let him stroke as they touched each other. Teased each other. Fuck. Maybe they'd-

The phone beside the bed trilled with a soft, melodic chime that seemed to bypass Greg’s ears and vibrate directly in his chest. His thoughts of Dina and Chloe evaporated, even as their soft voices floated through the room. He answered just as Dina had a few days ago.

“Room Service,” a voice purred. It wasn’t the automated system. It was Linny. "One of the guests has ordered you off the menu."

Greg’s cock twitched at the sound of her. He could still feel the phantom weight of her massive breasts against his back, the way she’d breathed suggestions into his ear while her nipples dragged across his skin.

"Yes, miss. I understand."

“Penthouse suite,” she continued, her voice dripping with that specific brand of True Tide authority that made obedience feel like bliss. “The bachelorette party is waiting for their server, Greg.”

"Yes, miss. I'll come right away."

It was the same way that Dina had been summoned, and now he understood how she'd felt.

The line went dead. 

Greg pulled on the white linen pants provided by the spa and took the elevator to the penthouse. He hadn't said goodbye to Dina or Chloe as he passed the open bathroom door. He hadn't even glanced in to see who's tongue was where. He simply did as he was instructed. And when the doors opened, Linny was waiting.

She was completely naked. 

The elevator opened right into the penthouse room. There were no hallways in which she needed to feign even the slightest modesty. 

"Welcome to the party, Greg," she said, handing him a drink which he knocked back immediately. It tasted like the one he'd be given before he'd met Chloe and Kenzie. Creamy and banana flavored. Then she handed him a second and he drank that back as well. And a third. Finally, Linny smiled and wiped some of the creamy drink from Greg's lips. Then she led him into the living area.

The penthouse was floor-to-ceiling windows overlooking the ocean, but Greg barely registered the view. The six women arranged on the sectional sofas and fur rugs were already naked, their bodies flushed and gleaming with massage oils. And their breasts… God, their breasts were enormous. Greg took slight notice of the empty glasses on the counter, each one containing a few green drops of the melon drink Dina had been guzzling, clinging to the sides or bottom. How many had Linny fed them? What had they looked like before they'd arrived here before they'd become these walking sex dolls?

"This is Cassidy," Linny said, gesturing to the woman in the middle. "Woman of the hour. Bride to be."

Blonde hair in loose waves around her shoulders, a tiara perched crookedly on her head that read BRIDE in pink rhinestones. Her tits were easily F-cups now, milky-white and veined with blue, nipples the size of thumbs pointing slightly upward.

“Greg,” she breathed, her eyes glazed with the spa’s signature arousal. “We’ve been waiting. Cindy said the room service here was... exceptional.”

Cindy, the maid of honor and Cassidy’s older sister, stood beside the couch. Twenty-nine, dark-haired where Cassidy was fair, with an athletic build and breasts that looked even larger proportionally. She held a half-empty glass of the melon nectar, her lips wet and swollen.

“Sister’s last night of freedom,” Cindy said, slurring drunkenly. “We need to send her off properly. And these,” she cupped her own massive tits, lifting them, “are apparently very good at getting what we want.”

The other four bridesmaids were similarly endowed. 

“They’ve been drinking since noon,” Linny explained, guiding Greg into the center of the room with a hand on his lower back. “The melon extract has them in a state of constant arousal and I've been adding vodka to each one. They deserve to have as much fun as possible. Don't you think, Greg?”

Greg’s linen pants were tented obscenely, a wet spot spreading from the tip where he was already leaking precum. The pressure in his balls was immense, a dull ache that demanded release.

“Banana Blast kicks in fast,” Linny observed, her hand sliding down to grip his erection through the fabric. “Look at him strain. He could fill a bathtub, ladies. Who wants to go first?”

The redhead named was Amber pushed forward first. She dropped to her knees in front of Greg, her freckled tits swaying heavily. “I’ve never tit-fucked anyone before,” she admitted, looking up at him with dilated pupils. “But I can’t stop thinking about it. How could I now that I've got these?”

Linny helped Greg step out of his pants, his cock springing free, thick and already dripping. Dina might have found herself surprised at how competitive he could have been with her earlier experience if she'd been here. 

Amber pressed her breasts together around his shaft. The flesh was warm, impossibly soft, enveloping him in velvet heat. As soon as Greg began to thrust, Amber’s head fell back, her mouth opening in a silent moan.

“Oh god, I can feel every vein,” she whimpered, squeezing her tits tighter around him. “Fuck them, please, fuck them hard!”

Greg’s hips moved on autopilot, driven by the programming and the chemical urgency in his balls. He pistoned between her freckled cleavage, watching his cockhead emerge and disappear, slick with her sweat and his own precum. The other women watched, masturbating, pinching their own nipples.

“I’m gonna…” Greg grunted. "I'm already…"

“Yes, yes, paint her,” Linny commanded. “Cover her face. That’s what you were brought here for, Greg. Tonight, that's your only purpose.”

Greg’s orgasm was violent and wrenching. The first spurt hit Amber’s chin with the force of a thrown rope, splattering up to her hairline. The second caught her across the nose and open mouth. The third, fourth, fifth… He kept coming, the Banana Blast turning his ejaculate into a thick, endless fountain. Amber’s face was glazed white, cum dripping from her eyelashes, her tongue darting out to catch what she could.

“Next,” Linny said calmly, handing Greg another cup of banana cream while the girls decided and Amber fell backwards, sputtering and smearing and cumming from the feeling in her tits.

Latina Maria took Amber’s place, pressing her darker, heavier breasts around Greg’s still-leaking cock as he chugged. He hadn’t even softened; the drink kept him rigid, hypersensitive, producing more semen than he’d ever thought possible. Maria’s tits were slick with oil, and she squeezed them tight, creating a channel of slippery flesh.

“Look at those balls,” Cindy observed, standing close now. “They’re so full and heavy. He’s like a stud bull.”

Greg fucked Maria’s tits with abandon, the programming stripping away his hesitation, his marriage, his identity outside of this room. He was Room Service. He was a provider of genetic material, a toy for these swollen-breasted women to use. Maria came just from twisting her dark nipples as she held her tits together for him, her body shaking as Greg unloaded another massive eruption across her face and tits, adding to the mess already coating her skin.

Tara was next, then Cindy, then Jade with her pierces nipple and tattoos. Each woman presented her enhanced breasts like an offering, and each time Greg would drink his drink and thrust between those soft, heavy globes, he painted them with increasingly voluminous loads. By the time he’d finished with Jade, his fifth orgasm in twenty minutes, the women were glazed, their faces sticky masks of his seed, their breasts dripping with it. Cum was everywhere.

But his balls were still heavy. The Banana Blast was relentless.

“Cassidy’s turn,” Cindy announced, her voice thick with lust as she scooped globs of cum from her face into her mouth. “The bride gets the finale.”

Cassidy lay back on the fur rug, her wedding tiara still perched in her hair. She held her massive breasts together, presenting a valley of cleavage that seemed to go on forever. “I want it all,” she whispered, her eyes rolling back. “I want to be covered. Head to fucking toe, stud. It's my party. Give it to me.”

Greg stood over her, sliding his cock through his fist. 

Cindy reached behind Greg. He felt her fingers, slick with oil and cum, trace down his spine to the cleft of his ass. “Men have a spot,” she whispered, her finger circling his puckered entrance. “And when you press it…”

She pushed inside him, one finger sliding deep, crooking upward to find his prostate.

Greg’s vision whited out. The sensation was overwhelming; not just the physical pressure, but the violation of his boundaries, the complete submission to the spa’s programming. His prostate was already swollen from the Banana Blast, and Cindy’s finger massaging it directly triggered something primal.

He screamed, his hips jerking uncontrollably, and then he was coming harder than he had ever come in his life.

The first spurt hit the ceiling. The fucking ceiling. The second caught Cassidy across the forehead with such force it splattered against the couch behind her. And then it became a torrent. An impossible volume that coated Cassidy’s face, her hair, her tits, her stomach, pooling in her navel. Dribbling out finally covering her crotch and her legs. Cindy kept fingering him, milking his prostate, and he kept coming, his cock jerking and painting her until she was unrecognizable beneath a mask of white.

When he finally finished, collapsing backward onto the rug, his cock still twitching weakly, Cassidy lay opposite him, completely covered, her chest heaving, her own orgasm rippling through her from the sheer degradation and fullness of it.

“Beautiful,” Linny said, stepping forward with a bottle of warmed oil. She began massaging the cum into Cassidy’s skin, using Greg’s seed as lotion, rubbing it into her breasts, her face, her throat. “I'll admit, I've never seen anyone drink so much of the Banana Blast in such a short time. I was curious what it would do to you."

The other bridesmaids, still glazed with Greg’s previous loads, crawled forward. They began massaging each other, using the cum as lubricant, their hands sliding over enhanced breasts and slick stomachs. 

Cindy mounted him first, sinking onto his still-erect cock, her own massive tits bouncing in his face. Tara and Maria began sixty-nining beside them, licking cum from each other’s tits. Amber and Heather sucked at Cassidy’s cum-coated nipples.

"Are you going to breed her?" Linny asked as Cindy bounced on his nearly unconscious cock. "Are you going to blast that banana cream into her fertile little pussy? She ovulating. I heard her tell her sister earlier."

Greg could barely comprehend the words being said to him. He grunted, hips bucking to meet his partner without a thought.

"Dina never wanted kids," Linny said, laying down beside Greg so she could whisper right in his ear. "Cindy does. Don't you?"

"Breed me…" was all she could manage to moan.

"You heard the girl. Cindy's ordering some extra room service. And it's about to cum."

Amber's face was deep in Cassidy's pussy, her body wiggling around in the pool that Greg had made. Jade was fucking herself with something from the kitchen. And there in the middle of all of it, Greg grunted on last time and shot his super-powered cum into Cindy's womb, then slipped out of consciousness.
