Before you or Wendy could say anything, another head splashed up out of the water. You were relieved to see the familiar orca-like face of Olivia. "Hey, Michelle, where the shell did you vanish to?" Olivia's eyes suddenly locked onto Wendy's dickless crotch. The orca mermaid sighed. "Michelle, I thought I asked you to leave these poor people alone."
"I'm sorry, Olivia," said Michelle. "But you do want your dick back, right?"
"Of course, I do!" said Olivia. "I wanted to fertilize your eggs with that thing, to start our own mermaid family. But... but if Wendy needs it more..."
Wendy blushed. "You know what? I'm starting to feel like a bitch. Keep your dick, Wendy. I'll see if your queen'll give me another one." Wendy looked at you. "You don't mind, right?"
"Of course not," you said. "It isn't worth crushing Olivia's dreams."
"Thank you so much, guys!" Olivia cheered. She thrust her crotch out of the water. "Fix me, Michelle."
"Sure thing, darling," Michelle said. She aimed the transformation staff at Olivia's pussy and its pearl began to glow. Within seconds, Olivia's cock had reappeared at the base of her tail.
The orca mermaid grinned at the sight of her returned penis. She gripped it and pulled back the foreskin and brushed a finger over the sensitive head. She shuddered at the wave of pleasure that surged through her hardening dick. "It's really back!" she cheered, a grin full of sharp teeth on her lips. "I can't believe it!"
"I'm glad you like it," Michelle smiled as she idly splashed her lionfish tail in the water. "It looks just as beautiful on you as ever."
"So," you asked. "Are you ready to turn us into mermaids?"
"Yeah," Wendy added. "I wanna ask your queen for a big uncut cock of my own."
Michelle crossed her arms. "After what you did to my girlfriend?!"
Olivia placed a consoling hand on Michelle's arm. "C'mon, Michelle. Go easy on them. Wendy did give my cock back in the end. Let's all try to be friends, okay?"
Michelle sighed. "Alright. You dick thieves are lucky Olivia's so nice. In spite of everything you've pulled, you can join is as mermaids." She aimed the staff at you, and the pearl began to glow bright.
