"And now for your reward," she heard Karyn say. "Luke, turn into a slime girl who feeds off sexual energy. The more energy you absorb, the more in control of your body you are and the more you can transform yourself."
Jen watched as Luke turned a shade of green, like he was sick, and...melted! Right onto the floor. Jen's floor now held a slime-green puddle, but as she watched, it began to take form. Rising up, the shape of a head here, an ass there, arms and legs took shape, eyes opened. Finally, a mouth gasped.
"Oh my goodness," Luke breathed. "I could get used to this."
"You better not," Karyn said. "You can transform yourself into anything you can think of with that body. A little reward for being on our side."
"Thank you, Karyn!" Luke exclaimed. "But I'm still having trouble getting all of myself together."
"That will come in time, dear, and after lots of sex. But first, a new name for you." Karyn paused in thought. "Luke, your new name is Emma, short for Emerald. You can only respond to or tell people your name is Emma or Emerald."

"Hmm?" Emma looked up. "Sorry I was concentrating."
"Not a problem Emma."
Jen finally piped up, "That was the sexiest thing I've ever seen, Karyn."
"Oh you ain't seen nothin' yet, Jon-girl," Karyn smirked. "Now about that little problem with the class. I think Emma here will be a good start to our plan..."
