Virgin classmate requests a penis drawing

A virgin classmate asks her friend to show his anatomy for an art project under the guise of study. He obliges, but the situation quickly shifts from innocent sketching to raw, desperate need between desk chairs. She drops her pencil and dives in, taking him deep into her mouth with surprising enthusiasm. Saliva drips down her chin as she swallows every thick pulse of his release. "More," she whimpers, eyes glazed with lust.
