Be stern.

"I'm sorry Valerie, this is out of my hands," you tell the desolate brunette. "The headmistress has full authority over you eligibility, and I think you're going to have to make your case to her."

"Noooo! Please Mr. Watts, please! I know she'd listen to you...I know she would....if you told her that you needed me to play...that you needed me on the team...about how much I do...." she begs, looking up at you beseechingly, her hands stroking and squeezing your calves.

You look at her, taking in her ripe young body and pretty, distraught face. Even though you know her apparent grief is at least half an act, you do feel some sympathy for her, and her submissive pose on her knees before you is making your cock start to twitch with interest. You try to **** your libidinous thoughts out of your mind, remembering Diane Naylor's warning, but this dangerous, manipulative girl in front of you is very hard to resist.
