The water grew darker the deeper Ariel swam, until even the moonlight vanished from above. The seabed had long since dropped away, replaced by what seemed like an endless abyss. Ariel took a deep breath as her breasts swelled with determination. She summoned the courage to dive into the heart of the sea witch’s domain.
Around her loomed a great ship graveyard. The only light came from the glow of lanternfish and the trailing tendrils of jellyfish. The forgotten vessels creaked, sounding like the screams of a ghostly crew. The broken masts and rusted hulls rose around her like a twisted cathedral. At the center of it all sat the skull of some ancient sea creature, which had been lost to time, now being used as the witch's hovel.
“Hello?” Ariel’s voice sounded small in the vastness. “Ursula… I have questions that need answers.”
A low chuckle slithered through the shadows. A dark shape rippled through the water and from the blackness Ursula emerged. She was unlike any siren Ariel had ever seen.
She was unbelievably stacked, her huge gravity-defying breasts made Ariel’s generous rack look almost insufficient. She wore no clothes instead a slick black tar clung to her curves. It slithered and shifted over her body as if it were alive, giving teasing glimpses of her smooth lavender skin beneath. Her bone-white mohawk curled back like a crashing wave, and her yellow eyes glowed faintly in the dark. But what Ariel found most shocking of all was instead of a tail, Ursula had six long tentacles.
“Oh, sweetheart! I have been expecting you,” Ursula purred, her voice smoky and full of amusement. “Let me guess, Daddy dearest still trying to hide those useless little meat-pouches of his?”
“I saw one!” Ariel said excitedly. “On a land dweller! It was… squishy and he made funny noises when I poked it.”
Ursula darted forward, closing the distance in a blink. Even though Ariel flinched a little she still held her ground. Ursula’s enormous breasts pushed against Ariel’s perky chest as they came nose to nose.
“Of course he did, sweetheart. That wrinkly little sack is their weak spot. All it takes is a little…” the witch cooed as her tentacles cupped Ariel’s breasts squishing them together. “…squeeze, and they’ll do whatever you want. That’s why Triton feared me.”
“You… knew my father?”
“I’m his sister, darling. And like any good big sister, I knew a swift kick between the legs would shut him right up.”
“But… merfolk don’t even have legs. My daddy doesn’t have those jewels… does he?”
“What if I told you that he used to? Back when he was young, before he was king.” Ursula’s grin widened, knowing she had Ariel in the palm of her hand.
“Really!?!”
“When he was young, your father found a magical lamp lost in a trench. With it, he erased our legs, sealing their weakness and our strength beneath one smooth tail. No more difference. No more desire. Just sleek, silent obedience.” Ursula’s fingers trailed up the shimmering curve of Ariel’s tail, pausing where the scales pulsed with heat. Ariel hadn’t known a part of her could ache so badly. “But you, darling, you’re like me. You don’t just want to know the truth. You want to feel it. Touch it. Press it beneath your foot and watch it squirm. I can give you that. But all magic comes with a cost. I can give you legs for a day… but the magic will have your breath. Once the spell takes hold, the sea will no longer welcome you. You’ll be human. You’ll walk on land… but if you stay too long beneath the waves, you’ll drown. So tell me, my little sea blossom, how badly do you want to feel?”
“Will I… have those hanging ball things?” Ariel shuddered at the thought.
“No, my dear. You’ll get something better. Something strong and beautiful. Something Triton took from you.”
Ariel’s fingers moved without thought, drawn to the throbbing heat that pulsed at the seam of her tail.
“Exactly! That is why I fought so hard against the Genie’s curse that twisted us all to be the same. I paid the price with these tentacles but I clung to this!”
With a sly grin, she lifted her squirming tentacles like a gown, revealing a tight, smooth pussy nestled between them. Ariel’s cheeks flushed pink, but her eyes refused to look away. In that moment, she didn’t care about her breath or the ocean. She wanted what Ursula had.
She nodded in agreement
Ursula’s smile turned wicked as she flashed her fangs. She began to chant in a low, throaty growl. Black clouds of ink coiled around them. Her tentacles slid up Ariel’s body, plucking away her shell bra. Ariel gasped trying to cover her breasts in embarrassment, but Ursula seized her wrists, pinning her hands behind her head. Another tentacle fondled her breasts, kneading and pinching her soft nipples until they hardened. Ariel whimpered as a final tentacle slid lower, rubbing exactly where that strange pressure had begun begging for attention.
“What are you doing?” Ariel squirmed away from her touch.
“Giving you what you desire!”
Ursula leaned forward, taking Ariel’s soft lip in hers. Ariel’s eyes went wide, not expecting Ursula’s tongue to slither so forcefully against hers. Ariel tried to resist, but Ursula held her tight in her grasp. Magic pulsed from the Ursula tentacles tracing Ariel’s body all the way to the tip of the siren’s tongue. The warmth started small, but it spread through Ariel's body. She arched her back as waves of unfamiliar pleasure coursed through her. While Ursela’s touch made her feel uncomfortable she realizing that resisting was useless so the mermaid gave in to the feeling of the witch's soft lips. Her eyes rolled back as she felt Ursula’s tongue flick against hers. A tidal wave of orgasmic magic washed over her body.
She finally let herself cry out in ecstasy as her tail split in half. Her scales flaked away, revealing smooth pale thighs and long shapely legs. Her delicate feet unfurled as her toes wiggled with excitement testing their new form. Ariel looked down at herself in awe. Her fingers slipped between her legs to explore. Her fingers first found a soft patch of red pubes before meeting her clit for the first time. She began to flick it softly. She bit her lip as her fingers explored further, sinking inside herself. She opened her mouth to let out a moan, but instead a rush of seawater flooded her throat. Her chest tightened and her lungs burned as the sea turned against her.
“Your body’s human now. You want to last long down here.” Ursula smirked.
Ursula pulled her in by the small of her back, their breasts pressing together. She took Ariel’s lips in hers again, making Ariel squirm as she twirled their tongues together again. As Ursula made out with Ariel, she pushed air into her lungs. Ursela carried her slowly towards the surface. Intentionally taking her time to extend their time together.
“Better get going before you run out of air,” Ursula said, breaking away from Ariel’s soft lips. She gave Ariel’s plump ass a sharp slap, sending a ripple across her taut new skin.
Ariel's legs kicked awkwardly through the water, her limbs not used to their shape. Her heartbeat thundered in her ears as she swam, faster and faster towards the surface, her lungs screaming. She knew Ursela hadn’t taken her all the way up so she would still struggle. Even with the air in her lungs her vision blurred. The last thing she saw before her vision went black was the soft glow of the moon penetrating the water’s surface.
A wave crashed against the rocky shoreline as the pale naked body of Ariel washed up. The waves rocked her unconscious form, making her breasts jiggle. Her red hair was tangled across her face, and her new legs sprawled out awkwardly in the surf. John, who had been building a fire to signal any passing ships, saw her glistening body in the moonlight. He ran towards the shore. Well, not really run, but more waddle since his balls were still swollen and bruised.
“Holy shit. It must be my lucky day,” he said, dropping to his knees. John didn’t recognize her as he was too busy staring at her soaked curvy body. “Okay… CPR. I can do CPR. Right. Chest compressions…”
He placed his hands firmly on her chest, making her soft breasts squish beneath his palms. John cupped them, giving a tentative squeeze, and let out an uncontrollable giggle of glee at how soft they felt.
“Focus, man. You’re saving a life here. A gorgeous, wet, unbelievably stacked life…” His voice trailed off as he continued to knead her breasts, pushing down but not before giving her nipples a pinch. He leaned in for mouth-to-mouth, but before her plump lips brushed against his, Ariel’s eyes snapped open, confused at first before quickly narrowing with anger as she felt his hands on her chest.
Without a word, her perfect leg shot up between his thighs, slamming into his nuts with a wet crunch. She felt his testicles compress against her smooth skin. The soft orbs gave slightly under the pressure before being crushed into his pelvis. John screamed as he rolled off her, collapsing into the sand.
Ariel looked at John cupping himself in a fetal position beside her and opened her mouth to laugh, but no sound came out. She pressed her fingers to her throat. There was no voice, just a wheeze.
Her new legs wobbled beneath her as she tried to stand. Her long hair clung to her breasts, giving her the illusion of modesty. John reached out to steady her, more from instinct than chivalry. His hands found a perch on her round butt, his fingers sinking into her soft flesh, feeling the toned muscles underneath. Without thinking, she took another uncertain step forward, planting her foot right onto the center of his swollen balls for support. John’s voice jumped an octave as he jerked back, causing Ariel to slip forward. Her legs flew out from under her, and she landed crotch-first on the ridge of a boulder. Her eyes went wide. Not from pain, but from surprise. She expected a surge of agony, but only felt the cold surface smack against her groin.
“Oh shit! Are you okay!?” John gasped as his knees clenched together in sympathy.
Ariel just blinked as she looked from her crotch to his. Her face finally broke out into a silent laugh as she wiggled her hips teasingly.
“That… that would’ve killed me,” John stammered, still clutching his throbbing balls.
Ariel tilted her head, giggling as she mimed punching herself in the crotch. She pointed to herself and shook her head, then pointed to him and mimicked his pained face, clutching her crotch in mocking sympathy.
“Come on now you must have felt something,” John said slowly, “you really didn’t feel it? Like… at all?”
Ariel shrugged, slapping her pussy hard for emphasis. She smiled with no reaction. Then she looked down at his balls curiously, then just to test her theory she slapped his nuts with all her strength.
John made a guttural noise as he toppled over. Ariel’s eyes lit up with excitement. She threw her hair over her shoulder and stretched her arms as if she were preparing for a workout. John’s eyes went wide with fear when he saw that smile. He tried to scoot away from her, but she placed her delicate foot down on his nuts to stop him. She felt them squish and flatten into the rocky beach as she applied pressure. She wiggled her toes digging them into his sensitive flesh.
“Please!” John managed to squeak out through his pain, his voice high-pitched and strained.
Ariel didn’t need a voice to communicate her amusement. Keeping her foot firmly on his nuts, she moved her pussy closer to his face. He could smell her arousal. Despite his agony, his cock twitched against her foot. He knew what she wanted, and if he obeyed her silent command, she might let him go. With a gulp John leaned in kissing her inner thigh first. The soft press of his lips sent little shivers down her legs. He turned to her pussy next as he began to lick it. She tasted sweet but salty. Her thighs tightened around his head as he explored her with his tongue. Every flick of his tongue brought a sharp jab, pressing his balls into the gravel. His brain didn’t know whether to keep going or to stop. But he knew if he stopped now his punishment would be a lot worse.
She grabbed the back of his head as she pulled him closer into her. Her eyes closed as she felt something she’d never felt before, a warmth building in her core that was slowly spreading throughout her body. He reached up between her thighs sliding his fingers into her. Her wetness made it easy for him to push them deep inside. He felt the warm walls of her pussy constrict around his fingers as she let out a silent moan. Her breasts jiggled as her breath quickened. Her new skin was soft and sensitive, making her orgasm come quickly. Her ecstasy rushed through her new body so intensely that her heels involuntarily slammed down, mashing his balls into the gravel with her full weight. John let out a strangled muffled scream into her pussy. His voice vibrated against her clit in a way that only made her climax harder.
After several aftershocks of pleasure, her body went limp as she slid off him. She collapsed beside him, her skin glowing with the afterglow of the orgasm. She rolled onto her stomach, propping herself up on her elbows. Her breasts jiggled from the movement as they pressed together between her arms. With a wheeze, John was finally able to breathe again without her weight on his manhood.
Ariel just smirked and gave his bruised balls a playful nudge with her toe causing him to yelp.
“Was that supposed to be a thank you?” he muttered, rolling onto his side and clutching himself.
Ariel just smiled as she rolled onto her back exhausted. She felt the warm fire on her skin as she quickly drifted off to sleep.
———
The fire was now just a faint glow from the remaining embers and the cool night air made Ariel’s skin rise with goosebumps. A low rhythmic grunt pulled her from her dreams. At first she thought John was just snoring, but the sound was too quick and breathy. She opened her eyes and saw a woman straddling John’s hips.
The woman’s pale skin almost glowed under the moonlight, her long black hair spilling over her shoulders and her heavy breasts bounced with each thrust. She rolled her hips bringing herself down onto John’s cock over and over again. One of John’s hands clung to her thigh while the other reached up to catch her breast. He groaned, half in pleasure, half in agony, Every time the woman came slamming down, her thick ass landed on top of John’s swollen balls.
Ariel’s mouth fell open in silent outrage. Without thinking, she just lunged at the woman.
The two women slammed together as their breasts flattened against each other. Their nipples rubbed together making them hard. Ariel’s thighs came down hard over John’s face, unintentionally straddling him. Her pussy was forced against his mouth. He let out a muffled gasp, which vibrated against her clit, sending a surprising jolt of pleasure through her.
She grabbed at the other woman’s hair, yanking it sharply back, finally seeing her face. Despite the black hair, her face was unmistakable. She had the same sharp cheekbones, the same full lips, and only one woman could have those massive, perfectly rounded breasts. It was Ursula, somehow in human form.
“What’s wrong, darling?” Ursula purred her voice sounding different. “Jealous I broke in your little toy?”
Ariel’s eyes narrowed. She knew that voice. It was hers. The siren had stolen her voice and was now mocking her by stealing her man. Ariel let out a silent scream as her nails scraped across Ursula’s face. Ursula responded by grabbing Ariel’s tits, twisting her nipples before shoving her back hard. Ariel clenched her thighs tighter around John’s head to hold her ground, her pussy grinding into his mouth. He choked, coughing against her clit, which made Ariel moan.
They wrestled atop of John, neither gaining an advantage over the other. Ursula‘s long nails clawed at Ariel’s ass, while Ariel yanked at Ursula’s hair. John’s body moved under them involuntarily shoving himself deeper inside Ursula, which only made Ariel madder.
Their bodies became slick with sweat, their breasts gliding over each other with ease. Each shift of weight crushed John’s balls beneath Ursula’s ass. His toes curled in agony as he kicked weakly at the sand.
Ursula snarled as she ground her hips harder into John to make him buck Ariel off. Ariel tried to grab Ursula’s thigh for support, but found John’s swollen sack instead. Ariel fell sideways her nails digging helplessly into John’s balls as they all tumbled down the sandy hill together. Their bodies tangled, breasts bounced, and limbs smashed into his balls until they came to rest at the bottom. John was left lying limp between them, his cock glistening with precum while his balls looked so full they might pop.
Ariel propped herself on her elbows, breasts pressing between her arms as she glared at Ursula.
“Oh, don’t pout,” Ursula smiled wickedly, “I was only proving a point. He thought I was you… for all of five seconds before he stopped caring.”
Ariel’s jaw clenched in anger.
“You had your fun with him on land, but now it’s time to put them in their place! Really make them kneel. The thing is, I need you. Only Triton’s seed can wield his Trident.” Ursela said annoyed. “And with it, we can undo his curse. Give the merfolk back their legs and give us our true power.”
Ariel paused, her chest still rising and falling from the fight. She looked down at John, his eyes glazed over, his cock twitching, his balls swollen to near bursting. He looked utterly broken and completely harmless. She thought about how easily he’d been fooled, how pathetically he’d begged earlier, and how satisfying it had been to feel him give under her touch. Ursula was right.
She opened her mouth to answer but closed it, pointing to her throat.
“That’s what I like to hear.” Ursula’s lips curled into a teasing smile. “Like I said, magic always comes with a sacrifice. Luckily this one won't be yours.”
John’s eyes went wide as he saw where Ursula’s finger was pointing.
“No. No, no, no, no—” he called out helplessly.
“Time to prove you’ve got what it takes, darling.” Ursula chuckled, glancing at Ariel.
Before John could scramble away, Ariel caught his ankles and dragged him through the sand to a nearby tide pool. She straddled his thighs as her hands wrapped possessively around his swollen manhood. She gave them a testing squeeze, feeling the weight of his testicles roll in her palm.
“So soft,” Ariel mouthed. She was fascinated by the yielding texture of his sack. She studied the blue veins pulsing beneath the taut surface. Without warning, she pressed her thumb firmly into the soft center of his scrotum. John’s scream broke the silence as his hips bucked wildly. She clenched her thighs, riding him like a wild bronco. As she withdrew her finger, leaving a temporary indent which slowly filled back as his testicles settled.
“No! Please! I…” John’s plea broke into a yelp as Ariel pulled his sack forward to line it up with the mouth of an open clam. The cool rim of the shell touched his sensitive skin, making his whole body go rigid with fear. His balls tightened from the chill, trying to retreat towards his body, but Ariel just tugged harder, stretching his scrotum taut.
Ariel glanced at Ursula excitedly for approval. The witch’s yellow eyes gleamed with cruel encouragement, which was all Ariel needed. With a swift motion, she flicked the clam shut. The heavy shell snapped closed around John’s testicles like a bear trap. His scream rang so high it was inaudible. He slapped aimlessly at the sand, trying to pull himself away, but Ariel held him firmly with her hips. The clam clung tightly to his sack, smacking against his thighs as he thrashed wildly, trying to get the shell to come off. Ariel clutched her stomach as it ached from her silent laughter.
John clawed at the clam’s shell. His fingernails scratched uselessly against the smooth surface. Her blue eyes were wide with wonder as his balls darkened between the shell’s jaws. She reached out to tap the clam lightly with her finger, causing John’s eyes to cross in pain. Without warning, Ariel pounced. She slammed her entire body weight onto the shell. Her breasts pressed together between her arms as she drove downward with a savage bounce. A sickening crunch echoed inside the shell.
The sudden compression from the clam’s shell forced his pent-up cum to erupt like a glacier painting Ariel’s pale breasts. She gasped silently at the sudden warmth splattering across her skin. Her nipples hardened instantly from the shock of the fluid. She looked down at her glistening chest with annoyance. His dick shuddered violently one last time before collapsing limp against his thigh. Ariel gave the shell a loving pat of approval before She hopped off his limp body, leaving the clam clamped snugly around his ruined manhood.
Ursula’s low chuckle vibrated through the night as she approached Ariel. She dragged a finger through the pearly mess, smearing a line up Ariel’s taut stomach and between her breasts.
“See? Landmen are fragile toys. Easy to play with, but easier to break.” She lifted her glistening fingertip to Ariel’s soft lips, her thumb pressing firmly against Ariel’s chin until her mouth opened, forcing Ariel to taste the salty tang of John’s release. “But Triton won’t be so simple.”
Ursela’s grip tightened around her cheeks, yanking Ariel into a hungry kiss. Ursula’s tongue forcing its way into Ariel’s mouth. Magic crackled between their tongues like static electricity. Ariel’s throat tingled as if something were lodged there. She tried to back away, but Ursula only deepened the kiss, holding her as if she owned her. Warmth spread through Ariel’s chest, the ache turning into a tingle of ecstasy.
Ursula’s hands glided over Ariel’s slick skin, rubbing John’s cum across her thighs and neck with slow, precise strokes. Shimmering green scales bloomed from wherever Uresla had touched. The sleek patterns snaked down her hips and thighs and coiled around her throat, making it look as if Ariel was covered in glittering emerald tattoos. Ursula finally broke away, letting Ariel’s voice spill out in a quivering moan.
“Better?” Ursula purred.
Ariel swallowed hard. “…Yes.”
“Now that you have legs for the land and the sea, let’s go show your daddy dearest how you use them.”
Ariel cast one last glance at John, curled around the clamshell in a whimpering heap. She tested her voice with a soft, almost wicked laugh. Side by side, the two women slipped into the waves, vanishing beneath the silver-lit surface.
