Try and take control.

She is good, she is really good. Your mother and your sister were top class sluts but this was different. With one hand she had you practically begging to cum. She had been stroking you with only one hand that couldn't even wrap around your cock fully, and yet you were already trickling cum out of your tip. The thick white precum was practically trickling out of your piss hole splashing onto her phone. You move a hand down and slide a hand up her short skirt sinking a hand into one of her big phat wobbling ass cheeks. She turns her head and looks you in the eye a playful smile on your face "oh, a bit presumptuous boy." She then begins stroking you faster with more ferocity, and you can feel your monster nuts tighten as you are on the brink of cumming. Then she lets go of your cock right before you are going to cum leaving you on the edge of orgasm. Your hands slides from her ass and your legs go a bit weak you are panting hard to catch your breath. The principal runs a single finger up all the inches upon inches of your cock as she walks over and sits on her desk.

She spreads her legs wide revealing her block thong digging into her sopping wet pussy. "You have been a bad boy and made a tremendous amount of trouble for me, so don't think you will be getting off so easily. You are going to make it up to me." You steady yourself and put one hand on your massive throbbing cock the words "I want to cum" repeating over and over in your head like a beast needing to mate. You begin to approach her cock in hand and she puts on toned leg up and pokes the tip of her shoe against your chest "No no boy, you are going to make it up to me like a gentlemen." She then points with one finger down, and you comply and drop to your knees. She then takes your head into her hands and guides you between her legs.
