I ask you to see me after class, assuring you that you're not in any trouble- I want to wish you a happy birthday. In fact, I have a little gift for you. I hand you my panties and confess I've felt some sexual tension over the last few months. I lift up my dress to reveal I just gave you the panties I was wearing and am teasing you with my pussy. I want to give you the rest of your gift and I unzip your pants and begin sucking your cock. You stop me after a couple minutes and throw me over my desk, fucking me from behind. You fuck me until you cum on my ass just as we hear a knock at the door.
