Play dumb and allow him to seduce you.

From Create Your Own Story

Your breath becomes heavy as Mr. Strats hand brushes barely against your leg. You look into his eyes and smile while pushing your leg against his hand, and your smile twists shyly as you glance obviously to his lips, and the back to his eyes. You can hear and feel his breath in your ear as he brings his face closer to yours. You gently bite your lip, which incites a visible reaction in your teacher. He closes his eyes for a moment before giving you his trademark, fatherly smile. "You're a very pretty girl..." He murmurs, brushing your hair slightly with his hand.
