Olivia put her hands on her hips and pouted. "I'm glad you like my dick so much, but I really need—"
Another head popped out of the water. It was a woman with pale, almost paper-white, skin and brilliant red hair. She had the same colossal, unclothed boobs and amazonian physique that Olivia had. As she pulled herself onto the shore, you saw that her lower half was the brilliant tail of a lionfish.
"Michelle!" gasped Olivia, trying awkwardly to cover her crotch.
"Hey there, Olivia!" Michelle said, smiling. "You've kinda been gone a long time, so the Queen sent me to— Hey, where's your dick, Babe?!"
Tears welling up in her eyes, Olivia pointed to Wendy and the massive uncut cock that now dangled between her legs.
"What the shell?!" gasped Michelle. "How under the sea did you manage to mess the spell up THIS badly, Olivia?! That's your DICK on that girl! YOUR DICK!"
Olivia sniffled, and Michelle's face softened. "I'm sorry, Babe. I shouldn't have shouted at you. I just want you to take good care of that cock of yours. You know we need it to spawn. But it's fine. I know the spell. Just give me that staff, and I can switch it back onto y—"
"WAIT!" shouted Wendy. "Has it not occurred to the two of you that maybe I wanna keep this thing?!"
Michelle glared at Wendy. "Lady, that is my girlfriend's penis you're wearing. It isn't right for you to keep it. Just let me magic up a new one for you."
"I had my first jizz with this baby!" Wendy argued. "I want THIS dick! Give Olivia a new one!"
"And I had my first time with Olivia with that dick! I think the two of us have a little more reason to get fucking sentimental about it than you. PLEASE let me give poor Olivia her dick back!"
You looked at Wendy, curious what she'd say.
