Flesh out the following prompt in dirty detail for at least 20 paragraphs, make it smutty. Skip the boring conclusion:
NAME_1 is a 16 year old, petite girl with medium boobs and a cute butt. She likes to wear tight white blouses, chokers, knee high socks and short plaid mini skirts.
She decides to hide under her teacher NAME_2's desk before the class starts and surprise him during his lecture by unzipping his fly and unveiling his small cock which can't even reach her uvula. NAME_1 is disappointed by his size but dutifully takes his tiny cock in her mouth. NAME_2 doesn't stop her and continues his lecture undeterred. The other students don't find out until she emerges from under the desk with an open blouse and cum in her face and hair.
