You call your student over to your desk after class as the rest of the school pack up to go to lunch. You tell her that her uniform isn't acceptable. Her tits are practically hanging out because so many of her buttons are undone. She becomes embarrassed and explains that her guardians can't afford to buy her so many new shirts as her breasts are growing so quickly. She demonstrates how the shirt won't do up by tugging the buttons together to no avail... you begin to grow hard. As she begs you not to send her to the Principal's office, you get an idea. She's heard how big you are but she's not prepared for the real thing. When you pull your huge, throbbing, veiny cock out from your trousers, she's in awe. She wraps her small hands around it before daring to put it in her mouth. She can barely fit her lips around the tip, her hands stroke the rest of you as she attempts to lick and suck your gigantic cock. You can hear how wet she is under the desk and, hesitantly, she stands to try to fit you inside her tight virgin pussy. Her wetness helps but again she struggles to get past your huge tip. She does her best to take you in various positions as she rubs her clit and fingers her tiny asshole, but how far can she slide down that girthy shaft?
