"Uh... nice to meet you, Theodora," Jenn said uncertainly. "That's a pretty human-sounding name for a mermaid."
"Well, I was born on Earth just like you," Theodora explained. "Then one day I was sucked through a mysterious painting and my legs turned into this silver fish tail. Lovely, isn't it?"
"It really is," Jenn answered. To her amazement, she found that mermaid tails were beginning to feel more natural to her than legs. Part of her hoped her changes would accelerate... and another part realized how insane that sounded.
"Thank you," Theodora smiled. "You'll all soon look as beautiful as I do. And there are other benefits as well. Would any of you girls care to guess how old I am?"
"Uh, maybe 35?" Olivia guessed.
Theodora giggled musically. "I'm actually 357 years old. Mermaids age ten times more slowly than humans. You should all live to be 700 to 1,100 years old."
"That actually sounds cool," Carmen smiled.
"It doesn't change the fact that she fucking kidnapped us!" Kelly snorted. To her dismay, she felt her legs getting itchier and itchier.
"I had nothing to do with this," Theodora laughed. "Those artworks have been circulating in your old world for generations. None of us really know who puts them there. Our queen just sends me to collect the confused new arrivals."
"What queen?" Jenn asked, barely noticing that she was absentmindedly tearing more strips of flesh from her legs and exposing more azure scales.
"Queen Tethys," Theodora answered. "She rules the underwater city of the mermaids. You'll get to meet her once you're all finished transforming."
"Will we get to do cool magic?" asked Olivia.
"Eventually," Theodora answered. "All mermaids have innate magical talent, but we must learn how to tap into it."
"You speak about mermaids a lot," Carmen observed, "but not a lot about mermen. Any reason for that?"
"Mermaids are all female," Theodora explained. "Well, mostly. Some of us undergo a ritual to transform our pussies into cocks so they can fertilize the rest of our eggs. Also, men who transform become essentially female, but their penises remain. You can undergo the ritual if you like."
"Hmm... tempting," Carmen smirked.
"Fucking seriously, babe?!" Kelly choked as she scratched furiously at her legs.
"I did always feel like I radiated big dick energy," Carmen laughed.
Jenn yanked off her panties as the itching spread to her crotch. "So we're going to live in your mermaid kingdom?" she asked as she dug her nails into her bushy red pubes.
"You will," Theodora nodded. "Oh, and we're properly termed a queendom. So, I suppose I should get to know all of you better."
"Sure thing," Jenn agreed. "I'm Jennifer Dean, but everybody calls me Jenn. I'm a college student and a huge mermaid fan. The feisty and snarky girl with the brown pixie cut is Kelly Porter, my roommate. The butch Latina girl is her girlfriend Carmen Rodriguez. And last but not least, the blonde cutie is my girlfriend Olivia Hansen."
"Oh, so you're all already attracted to women," Theodora smiled. "That spares you some adjustment."
"Adjustment?" Kelly asked, raising an eyebrow.
"Girls who turn into mermaids invariably become lesbians shortly after transforming. It's the instincts of an all female species kicking in, you see. Oh, and I'd strip nude if I were you. Your clothes will be ruined once your legs start fusing."
Kelly rolled her green eyes. "Greeeaaat," she sighed sarcastically as she pulled down her panties and exposed her pussy. "This day just keeps getting better and better."
