Give Brooke a heavy dose of her own medicine

The students that have gathered are rapt with suspense as you begin to explain your modifications to the plan. Once they learn it's actually Brooke's face Mrs. Barker will be sitting on, their faces shift to anywhere from solemn understanding to mischievous grins. Brooke wilts and crumples.

"Stand up straight, you delinquent." Brooke fakes a smile and corrects her posture, so you continue describing your adjustments to the punishment. " You will both remain until Mrs. Barker gets off, but don't worry, we won't let anyone interrupt you, as in your stupid, busted plan. Instead, when another student needs your attention, you can keep working on Mrs. Barker, and serve your fellow student with your hand..."

"Great..."

"...for a while, but if he hasn't cum after three minutes, he will vacate the spot for the next guy," she seems confused, so you draw out the pause, "and he will move on to your pussy."

"No, come on!" Until now, Brooke, the students, and even you had thought the **** you laid on Stella was beyond the limits, stripping her completely nude and humiliating her as you did, but the position you gave yourself with the Rulebook has changed everything. You want pretty badly to take her for yourself, and you're pretty sure the position of Female Behaviour Monitor allows it, but you decide it's not how you want to stamp your v-card. As Brooke and Mrs. Barker get in position, the first male student is already pushing aside contenders to get in there.

This first one is another big bully himself, it's Fred from Miss Fielding's class. As he's whipping his dick out for Brooke, you announce the final detail:

"Five points extra credit if you jizz on Brooke's face, 10 if you unload on Barker's!"

Fred has a half-chub Brooke's already working hard on. "Hell yeah, my grade could use it!" He thrusts at the air ludicrously as Brooke strokes his cock to full mast.

You're satisfied with your work here, Brooke is ruined. Barker will leave you alone, while she's busy and afterwards. You stand content with your work. Maybe you should add another Rule to the book?

A delicate touch on your back grabs your attention. Lilly is standing next to you. She slides her hand down your shoulder blade, to the small of your back, and says "I admire your work, Michael." She reaches into your waistband, squeezing your butt a little.
