Brenda, Fionna and Lina were the leaders of the monster club of their highschool, a club were the members shared their interest and love for multiple fictional creatures or modifications of existing ones, at some point they asked themselves how the school approved their club but they didn't matter. The place had a friendly environment full of nice people, however only the three girls knew about their own secret, a bigger passion for monsters than the other members, at the point it was their fetish, but only they could know.
One day the leaders reunited at Fionna's house, talking about their favourite subject, it was mainly a conversation between Brenda and Lina while Fionna browsed in her computer.

"Well, if you insist I want to be the first!" Lina took of her shorts and panties exposing her fully naked body and hairy bush in her vagina.
"I don't think that was necessary..." Brenda sighed.
"Who cares? I'm going to transform, right? Then I don't want this things to rip off"
"Okay, let's start" Fionna put her hands on her keyboard.
