Rub your dick all over her face

"Why don't you stick out your tongue?" you suggest to Professor Porter. She happily complies.

You step forward and start to rub the swollen head of your penis over her soft, wet tongue, enjoying the rush as much as the physical sensation. Slowly you begin to rub the head of your rapidly hardening cock all over the professor's face. As your cock hardens, you use it to slap the side of her face, before slipping it into her mouth.

You pump away at Professor Porter's mouth, then pull it out. Your hard shaft is glistening with saliva, which you gleefully smear all over your instructor's face. You sigh with pleasure as you rub and smack your cock up and down her face before stuffing it back into her mouth.

Before long you feel yourself getting close to climax. It won't be long now before you cum. And by the feel of it, this might be your biggest load ever....
