You've been horny all day, so you decide to jerk off quickly at your lunch hour before your students come back... but you forgot to lock the door, and one of your failing students comes in to ask a question about the homework. She sees you jerking off and is disgusted-- not only by you being a pervert, but at the size of your tiny dick! She insults you, and threatens to tell the principal if you don't raise her grade. Your offer of a C isn't good enough. She makes you pull your pants down and continue jerking your little dicklet in front of her, mocking you the whole time. Wouldn't it be so embarrassing if you got fired and everyone found out about your sad little penis? Your dick is the smallest one she's ever seen! You're so turned on you've become desperate to cum, and she only gives you permission once you've agreed to give her the A. Eww, don't get your nasty cum near her! Gross!
