"Alright, what color tail would you like, Tori?" Tiffany asked the auburn-haired recruit.
"Green, I think," said Tori. "I like to keep things classic."
"That's good," Tiffany smiled. "We stock plenty of green." She opened a treasure chest that was sitting in the sand, revealing several clear class bottles whose contents shimmered in every color of the rainbow.
Tiffany selected a green bottle. "Stand still and spread your legs apart, Tori."
Tori nodded and spread her legs apart. "Like this, Tiff?"
"Yeah," Tiffany said. She knelt in front of Tori and poured a wad of sparkling green paste from the bottle and onto the palm of her hand. She pressed her hand onto Tori's thigh and began smearing the paste all over the lower half of Tori's body. Tori watched with fascination, shuddering with arousal as Tiffany speared the emerald paste over her pussy and into her asscrack.
As they watched Tiffany work on Tori, Michelle and Melanie grabbed their hardening cocks and began to masturbate, tugging their foreskins back and forth over their tips. Melanie was beginning to regret passing on joining the Mermaid Club when she'd considered it. Oh well, it was never too late to change her mind.
Tiffany worked her green-coated fingers down Tori's long legs, coating them with the green paste as she went. Soon, she reached Tori's bare feet. She began by covering the tops of the feet before dexterously sliding her fingers between the cheerleader's toes and lifting up each foot to paint the soles. As soon as Tiffany finished painting, Tori, the green paste absorbed into her legs, leaving them the same color as they'd always been.
"Was that... supposed to happen, Tiff?" Tori asked, perplexed.
"Of course," Tiffany smiled. "You'd better lie down for the next part."
"Trust Tiff on this, Tori," Guadalupe grinned, waving her red tail at the new recruit. "She's done this a million times."
Tori did as she was told and settled down on the white sand. She suddenly felt her legs begin to tingle all over. She watched in amazement as little green scales began to push out of the skin of her legs and coat them. Soon, her legs her covered in a coating of shiny green fish scales! Before Tori could admire them properly, her legs involuntarily pressed together.
"Ooh, I think your tail's starting to form!" Melanie said excitedly as she jerked off.
Indeed, the flesh of Tori's legs was beginning to knit together. Inside of her, the cheerleader could feel the bones of her legs fusing. Her feet started to elongate, flattening as they did. Tori gripped her tits as she savored the oddly arousing sensation of her body's piscine metamorphosis. Before long, Tori's feet had been replaced with a set of magnificent fins. She stroked her competed green tail reverently. She was a mermaid!
At that moment, Michelle and Melanie felt their orgasms hit them. They moaned and shrieked with ecstasy as their dongs twitched and blasted out long ropes of cum that soaked into the sand.
"Look at my tail!" Tori shouted gleefully. "Isn't it gorgeous? I'M A MERMAID!!!"
"Glad you like it, Tori," Tiffany smiled. "Welcome to the Mermaid Club."
"And now we can focus on the dicks," Brianna. "Can't wait to have one again!"
"Never fear, Bri," Michelle grinned, patting her own girthy dick as the tip retreated back into its velvety foreskin. "We brought plenty for everyone."
