Make the girls compete against each other

“Yes, I know you have to hurry for the cheerleading tryouts,” said Mr. Horner. He took the bag from Amy. “That's why I brought your uniform.”

“Cheerleading? What the hell...” Sheila blinked as Mr. Horner used the bone to adjust her world view. “Oh! Right, the tryouts.”

Sheila snatched the bag away from the Janitor and ran into her bedroom, anxious not to be late. Horner sat on the couch and Amy sat in his lap. She wrapped her arms around his neck and kissed him until Sheila came back.

“What are you two still doing here?” yelled the dark haired girl, now wearing a skimpy red and black uniform like Amy's. “I didn't ask you to come in, you- Wait... Amy?! What are you doing here? Get out!”

Horner smiled and wished for her to accept what he was about to say. “Why should we leave? I'm the coach and this is where we're having the auditions for head cheerleader.”

All the anger drained from Sheila. “Oh! I'm so sorry, I don't know why I didn't recognize you, I can be so dumb sometimes.” Sheila laughed in her best airhead impression. It was obviously fake, but done so flirtatiously that Mr. Horner could tell that this bitch had probably gotten away with a lot. Sheila looked at Amy with a much more sour expression. “I can see that someone is trying to get an early advantage.”

Amy, still sitting on the “coach's” lap, stuck her tongue out at Sheila. “You did a hell of a lot more with the coach to become head cheerleader in high school!”

“Get over it Amy, that was a long time ago!” The pretty black haired girl suddenly looked very confused. “Actually... that was years ago! Why am I doing cheerleading auditions after I finished law school?”

“That doesn't matter,” said Mr. Horner, gripping the bone. “The only thing that matters is winning.”

“Right!” said Sheila, regaining her determination. “And I always win, don't I, Amy?”

Amy bolted up and stood chest to impressive chest with Sheila. “Not any more! I've got the advantage with the coach, now!”

“Well,” said Mr. Horner dramatically, “...maybe. You have a tight little pussy, but now that I've fucked it, maybe I want to give another pussy a try?”

Amy looked crushed that sleeping with the coach wouldn't automatically make her win. Sheila smiled smugly at the disappointed blonde girl.

Horner smiled, too. “Let's get started!”
