"Alright, Child. I'll agree to turn you human... but I have a few terms that must be met." The sea witch cackled as she loomed over the nervous little mermaid.
Marina trembled before the frightening woman, but held her ground. 'I can't run away now...' she thought. 'I just have to become human... I have to see him again...'
Just a few days earlier, the young mermaid had travelled to the surface against her father's wishes. There, she'd seen a handsome prince walking his horse along the shore, and instantly fallen in love. She knew the only way to be with him would be with the help of the mysterious sea witch, and so, she'd come to her, pleading desperately for the old crone's help.
"I'll do whatever you want!" she said aloud. "Just do it! Make me human! please!!"
The sea witch gave Marina an evil grin. "Alright, then." she said, before gesturing her arms as she began to recite in a strange, ominus dialect. "Mortallah fortunence! Humanous transformicus ballah!" The water around them began to swirl and glow, and Marina felt her long, black hair whipping around her in it's wake.
"Hezmorale vocalose no dictato fore amourosola!!!" The witch finished her spell by casting an explosion of light at the seabed between them. The water bubbled around Marina, and she lost sight of her surroundings.
When the water cleared again, she looked down to see her tail had disappeared, and in it's place sprouted two long, smooth legs.
"It is done, Child. And now, my price!" The witch made a coaxing motion, and Marina coughed as a ball of light passed through her lips and floated to the old woman's hand. "I have taken your voice as payment." she said with a cackle. "You have three days. In that time, you must obtain your true love's kiss, or your voice is mine forever and you will never be able to return to the sea. I've left you your gills, but they will close up soon, and won't open again until you have succeeded."
She gave a cruel laugh and continued: "If I were you, Pet, I would make for the surface quickly, or you're likely to drown here and now!"
Marina gasped as she felt her gills closing and realized she had to move fast. Kicking her human legs clumsily, she struggled to swim her way up, until she burst through the surface and took in a deep gulp of air.
Panting for breath, Marina swam weakly to a nearby rock and pulled herself up onto it. She rolled onto her back, her chest heaving and her naked breasts rising with her laboured breathing. Once she caught her breath, she sat up and studied her new body with curiosity.
She was pleased to find she had two very human looking legs for walking on land, and grinned when she wriggled her toes. She found her new extremities strange and somewhat alien, but amusing. When she looked between her thighs, however, her brow furrowed in confusion.
'Is this right?' she thought to herself. The little mermaid reached for her crotch, wrapping her fingers around a limp, smooth shaft of flesh protruding from between her legs. The appendage began to harden as she touched it, and Marina sighed as she began to feel a peculiar, pleasurable sensation.
With her other hand, she reached beneath her gradually hardening cock, and jolted when she found a soft, dampening crevice there. Touching that gave her pleasure too, and she chewed her lip, her gallant prince temporarily forgotten as she continued to explore her new, strange body.
'Oh... what is this... It feels so... good...' she thought. She lifted her hand, studying the wetness that coated her fingers.
Licking her lips, she quickly began to rub both her growing shaft and dampening slit simultaneously. Her breathing once again grew shallow. In moments, she was totally absorbed in the increasing titillation between her legs, losing all sense of her surroundings until another voice broke the silence amidst the calm waters.
"Marina!"
The naked girl jolted upon hearing her name being called. Another mermaid had just surfaced right in front of her. She was identical to Marina, apart from the tail and fins she still sported underwater.
"Sister! What have you let that sea witch do to you?!?" the newcomer cried.
More heads began to pop out of the surf all around Marina's rock. Soon, all 6 of her identical sisters were looking up at her from the water. The one who'd first surfaced, Brooke, swam closer with a concerned look on her face.
"Oh, Sis! You've got legs! But, what is that... that thing you've got in your hand?"
Curious, Brooke reached forward tentatively, before grasping her sister's cock firmly in her grip. Marina tossed her head back at her twin's touch, and pumped her shaft forward automatically between the girl's wet fingers. Brooke looked up at her in confusion. She could see the pleasure plainly on her identical sister's face.
"Do... do you like that? Does that feel good?"
Unable to reply, Marina simply nodded vigorously, her hips rotating involuntarily as she grew increasingly desperate for more. Wanting to help her sister, Brooke began to pump her fist uncertainly along the growing shaft. Her twin seemed to really enjoy that, so she continued, fisting her cock with growing speed.
The other 5 mermaids watched in relative silence, both curious and a little frightened by what their sister had transformed into. They murmured quietly to one another, but neither of their sisters paid them any attention.
Brooke was masturbating Marina furiously, now, her eyes focused completely on the girl's bulbous cock. She found the appendage oddly beautiful, and licked her dry lips as she worked. The head suddenly began to leak a thick, creamy precum from it's tip.
"Oh no! What's that stuff? Should it be coming out like that?" she asked. Unsure of what else to do, she leaned forward and licked up the oozing fluid.
The feel of Brooke's tongue made Marina shudder. She reached down clumsily, grabbing her sister by the back of the head and pulling her face back toward her crotch. Brooke squealed, but allowed her twin to force her cock into her mouth, whimpering as it pushed past her open lips.
In seconds, the curious mermaid was sucking eagerly at Marina's shaft, finding the taste absolutely wonderful.
"You girls... have... got... to try this!" Brooke gasped between slurping noises, unable to pry her face away from her sister's delicious manhood.
Marina, meanwhile, was in a state of bliss unlike anything she'd ever experienced in her young life! Her skin glistened with sweat, and she rolled her hips back and forth along the surface of the rock, pumping herself steadily down Brooke's smooth, luscious throat.
Feeling her pleasure beginning to peak, Marina's eyes screwed shut, and she let out a silent scream of pleasure before pumping gobs of sticky white fluid into Brooke's open mouth. Her sister squealed in surprise, but quickly clamped her lips around Marina's throbbing head, gulping down as much of the salty cream as she could take.
Marina's stomach heaved as she trembled with pleasure, her orgasm overtaking her completely. She gripped Brooke by her wet, tangled hair, holding her face in place tightly as she fucked her hot, delicious mouth over and over again.
Finally, her strength gave out, and Marina collapsed onto her back, panting and gasping for air once more.
Brooke pulled back, smacking her lips as she swallowed the last of her sister's spend. As she savoured the remaining droplets, she could feel a strange tingling in the lower half of her body.
"Brooke!" Hailee, one of their other sisters, suddenly cried out. "What's happening to you?"
The confused mermaid looked down in time to see her tail beginning to transform. The water around her began to swirl, and she could no longer see what was happening. In moments, she suddenly found it hard to stay afloat, and scrambled up onto the rock beside a still recovering Marina.
Brooke looked down in shock at her own pair of newly sprouted legs, complete with cock and vagina, exactly like her mute twin's! When she went to voice her surprise, she found she too had lost her ability to speak!
Marina, having recovered from her orgasm, slowly sat up again, noticing her newly transformed sister for the first time. She chewed her lip, finding this development strangely arousing, and reached out to gently stroke her twin's soft thigh.
Brooke shivered, feeling her cock begin to harden and the pleasure that came along with it. She licked her lips and reached forward, grasping Marina's shaft once again.
Before the sisters could start pleasuring one another, however, they felt more hands touching their lower bodies.
"No, guys! Not you, too!" Hailee cried. "You know what'll happen if you do that, look what happened to Brooke!" She was protesting loudly, but at this point was being completely ignored. Two more of her twins, Delphine and Choral, had already begun to touch their cock sporting sisters, and were strangely eager to have a taste for themselves.
"What do you think, Del? Want to give it a try?" Choral asked. "It sure looked like Brooke was enjoying it!"
Delphine couldn't take her eyes off of Marina's throbbing shaft. "Oh, definitely, Sis... I don't know why, but I've just gotta get my lips around that thing!"
Marina and Brooke held each other close, their hands stroking one another's excited breasts as they watched their other sisters take them into their mouths. Delphine was enthusiastic from the start, slurping and mewling as she worked hard on Marina's throbbing phallus. Choral worked slower, running her wet tongue gradually and deliberately over the surface of Brooke's spongy cock head, and luxuriating in it's flavour.
As the remaining sisters out on the water watched, they couldn't help but grow curious, too. Even Hailee, despite herself, was beginning to long for a chance to taste one of those strangely alluring appendages. Her two remaining sisters, growing bolder, swam up beside Delphine and Choral.
