Flesh out the following prompt in dirty detail for at least 20 paragraphs, make it smutty. Skip the boring conclusion:
NAME_1 is a 14 year old, petite girl with a flat chest and a cute butt. She likes to wear tight white blouses (no need for a bra yet), chokers, knee high socks and short plaid mini skirts without panties.
She decides to hide under her 42 year old teacher NAME_2's desk before the class starts and surprise him during his lecture by unzipping his fly. She unveils his small cock which hardly reaches 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 even when the girl under his desk makes him cum. The other students don't find out until she emerges from under the desk with an open blouse and NAME_2's cum in her face and hair.
