To punish her for being too forward

Imogen looks puzzled when you use the tip of one finger under her chin to gently push her mouth closed, but her expression is soon replaced by one of misery when you slap her cheek as hard as you can, snapping her head to one side.

"Look at me, Imogen, and don't turn away when I slap you."

Tears are already forming in the sexy brunette's green eyes when she fixes her gaze on yours to await the next smack. You are careful to only hit her cheeks and not her ears, as you have no wish to perforate her eardrums, alternating left and right to punctuate your words:

"Demure—" *SLAP* "—young—" *SLAP* "—ladies—" *SLAP* "—never—" *SLAP* "—throw—" *SLAP* "—them—" *SLAP* "—selves—" *SLAP* "—at—" *SLAP* "—men." *SLAP* *SLAP* "There's—" *SLAP* "—a—" *SLAP* "—difference—" *SLAP* "—between—" *SLAP* "—making—" *SLAP* "—your—" *SLAP* "—self—" *SLAP* "—available—" *SLAP* "—and—" *SLAP* "—acting—" *SLAP* "—like—" *SLAP* "—a—" *SLAP* "—slag." *SLAP* *SLAP* "Do—" *SLAP* "—you—" *SLAP* "—under—" *SLAP* "—stand?"

"Yes, Professor. I'm sorry." Imogen is sobbing now, her face red and swollen, but she hasn't looked away and her head only moves a fraction with each impact. "I'll behave more modestly in future."

"Good. Keep your mouth closed until I finish slapping you."

You continue to smack her burning cheeks firmly until your resilient palms start to sting from the repeated impacts with her delicate flesh. Imogen's face is now thoroughly bruised and her decolletage glistens with the tears which have flooded from her eyes. You sit back, the sight of the contrite and well-punished girl at your feet stirring your desire once more.
