In a sudden burst of carnal hunger, our bespectacled librarian transforms from prim and proper to a ravenous slut. She engulfs his cock, her glasses fogging up as she takes it deep, upside down, and with unbridled enthusiasm. His thick member pounds her throat, the bed slamming against the wall with each thrust. Her moans are muffled, eyes watering, but she's insatiable, begging for more. He unleashes a torrent of cum, filling her mouth and spilling out, as she gulps it down, savoring every drop.
