"Let me try one more time," said Olivia. "I'm sure it's just a matter of practice." She pointed her staff at the two of you once again and concentrated with all her might. A green flash blinded you and Wendy. Once it subsided, you noticed something different about Olivia... her dick was gone!
You glanced at Wendy, and you Spotted a bulge in her jeans. She hastily unzipped her jeans and pulled down her panties. You suddenly discovered the fate of Olivia's dick: it was hanging just beneath your girlfriend's curly red pubes! Even flaccid, that dick had to be a good six inches long, and the foreskin's overhang added about another inch to the length. The penis had changed color to match Wendy's caucasian skin tone, but it was undoubtedly the same monster cock that had once been Olivia's pride and joy. "What the hell?!" Wendy shrieked as she grabbed panickedly at her new appendage.
"You've got her dick, Wendy!" you gasped.
"What the shell?!" Olivia shouted as she pawed at her now-smooth crotch. "My dick! My gorgeous dick! How the SHELL did I fucking do THIS?! Give it back! It's mine, and I need it!"
"You think I fucking know how to take this off?!" Wendy said, rolling her eyes. "Because I DON'T!! It's not like this is a fucking strap-on!"
"But I'm a fertilizer!" moaned Olivia. "I NEED my dick! Michelle's so excited about spawning, and she really wants it to be MY cum that fertilizes her eggs. What am I gonna do?"
"Don't ask me!" you groaned. "You're the mermaid!"
