"It worked!" said Sam, practically squealing in delight.
"Of course it worked!" said Kyle. "I'm a frog-man now. Why?"
"Do it again" asked Becca. The girls weren't laughing anymore.
"Huh?"
"Your tongue..."
Confused, Kyle flicked out his tongue again. The girls definitely squealed with delight.
"Here's the deal, Kyle" explained Becca. "We'll change you back and we wont tell anyone what we did to you. But you have to do something for us first."
Sam nervously chewed on her lip.
"Can I go first?" she asked Becca. "I know you made this possible, but..."
"Okay, but only if I get to watch."
"What are you going to make me do?" asked Kyle.
Samantha walked across the room to Kyle.
"Have you fantasized about me Kyle?"
"What?"
"Be honest. I've seen the way you look at me when I ask you for homework help."
"Okay, yeah."
"Stick out your tongue again."
Kyle flicked out his frog tongue for the third time and Samantha visible shuddered with delight.
"I've got to admit something to you Kyle: I have a bit of a strange fetish. Becca will change you back when this is all over, but first..." Without warning Sam pulled down her pants. "...I want to feel that long, slimey tongue inside of me."
