Nina flashed for a moment with fear and anxiety. She figured that she was pretty sure about her not becoming a merman, but what of her partners? Izzy was always partial to both sexes, but she wasn’t. Moreover, she froze with frustration and anger, all her life she’d fought her mother tooth and nail for her own identity as a lesbian. She hated the idea of that being changed by anything that wasn’t one hundred percent her will. These mermaids seemed accepting enough, sure, but did she understand why she would be against this? Would she trade one kind of discrimination for another? Would she simply not care, effectively brainwashed by this underwater magic? She didn’t have much longer to wonder as her transformation rapidly accelerated, and soon it would be all that was on her mind.

Meanwhile Deme floated there while her companions sank to the water. She knew her change would be shorter than theirs, still, what would it mean for her? She knew that merfolk who took the ritual invariably came back substantially more beautiful than before, but what beauty would she become? She enjoyed her femininity, and deep down she dreaded losing it. She found herself nigh obsessively monitoring her breasts and touching her face, vigilant for the first sign of a shrinking of her chest or a hardening of her jawline.
————
While her partners languished in anxiety, Izzy had no such troubles. She knew what she was, she knew she was becoming her truest self, come what may, and she opened her arms wide for it. Rather, she found herself sizing herself up with her arms and exploring her body as her chains hit her like a flood tide, faster than the other two by a good deal.
First was her dark tan skin softening and rippling like a wave under her muscles and skin. She watched as it softened… so that was it, she was keeping her womanhood it looked to her. That was good, she knew Nina would need that kind of stability, she knew deep down she wouldn’t be taking the possible change in her sexuality well. Still, she marveled as every blemish on her bronze skin flashed away, accentuating the sharp muscularity of her athletic runner’s physique, soon to be a swimmer’s build, she thought.
Soon, she found herself glancing over to Nina, and she liked what she saw, she liked it so much that she let her hand explore southward. She imagined neither of the other women would begrudge her.
—————
What Izzy saw was Nina’s full nude glory. Much like the shell had dissolved to sand, she watched everything Nina was wearing do the same. Her hair, which was already starting to turn gradually, was overtaken almost from the off. She watched as a brilliant sapphire blue coloration cascaded through her long hair like a waterfall, soon giving her an incredible and totally natural look as it seeped into her eyebrows soon after. Nina proper herself up on her elbow to watch, her already blue eyes now sparkling azure were half-lidded and she panted, looking incredibly sensual and aroused.
—————
Deme’s libido was not unaffected either, she licked her upper lips as they began to turn a green hue like her hair, her whole face graced with a kind of exotic looking beauty makeup. She knew humans found that sort of thing attractive on their own, but merfolk didn’t truly have a way to replicate it undersea. She idly began going from checking her breasts to groping them as she found them growing, not shrinking. “Oh thank you goddess…” she purred.
———-
Izzy was now going to town on herself, two fingers deep in her moistened entrance as her short brown hair was crowned in the amethyst purple she’d be wearing for the rest of her days. She was moaning loudest of the three, her eyes squeezed tight as her body rocked in the ecstasy of becoming a thing of myth and legend. She squeezed her legs tightly down, inviting them into coming together as her legs knitted together, being kissed by scales that had a dazzling gradient going from pale lavender to deep royal purple top to bottom. Much like Deme, she found her tail didn’t end neatly on her waist. While the born mermaid’s went along her sides, she found hers crawled up her back and over her toned arms. She began to coo more and more as she got closer, her already busty chest becoming a massive D-sized endowment. The glorious tingling of her nipples stretching and hardening as they grew to match her breasts was enough to push her into climax. She released a big cloud of discharge into the sea from her transfigured womanhood as a glorious and ostentatious tail fluke unfurled from her shrinking feet.
—————
All the while Nina had been filling out as well, she watched as her generally petite and rail thin, curveless shape blossomed out into a shapely and sleek body type. If Deme had her assets in the rear and Izzy was blessed with the bosom, then it looked like Nina was getting the wide hips. She shamelessly caressed herself tenderly, imagining one of her mates doing it as her graceful fingers teased her flat and sculpted stomach down her wide, flared hips and rounded thighs. She watched as her fingers morphed into webbed appendages with stunning blue webbing joining knuckle to knuckle. Soon after her legs were bidding their final farewell, her legs erupting in a shower of navy, sapphire, and even white dots. She could deny herself no longer and began to ferociously tend to her swollen and begging petals. She gasped to the discovery that those webs felt amazing inside her, draping her inside folds in a silken caress like no human equivalent could match. She erupted hard and forcefully at that, her back arching as she expelled powerful squirts of her fluids outward. Her scales didn’t march much past her waist unlike the other two, instead the extra scales moved up her hands and covered nearly up to her shoulder like a set of skin tight sequent gloves.
—————
Deme admired the progress as the two women filled out their new mermaid forms, truly, they were the most beautiful creatures she’d ever seen, and as their fluids began to permeate the water, she found the horniness they were experiencing starting to leech into her, even as she was already leisurely stroking her pussy. Her pace picked up, she knew she’d have to climax as well to complete this step of the mating ritual, and oh how she was excited for the final step now. She watched as Izzy and Nina rounded out their transformations, getting the signature webbed ears and guiding fins on the hips characteristic of merfolk kind. Even Nina was growing in a beautiful and striking dorsal fin along her spine, an uncommon but not unheard of variation on the mermaid form, and a symbol of exceptional beauty in their culture at that. Seeing that pushed her over the edge as she gasped when she saw it, and it made her cum fiercely, her fluids mixing with the others.
—————
Al three mermaids spend a moment of two recovering, but it was a brief moment indeed. Their bodies cried out for release again, and their pheromones were flowing between them thick and fast. They needed to share no words as the three mermaids dashed for each other, ready for a collision of pleasure.
