With her short skirt hiked up and ass exposed, the horny coed bends over the professor's desk, presenting her glistening, untouched asshole. The professor, enticed by her boldness and tight, young body, lubes up his massive cock and slowly pushes it into her virgin ass. She winces at first, but soon relaxes, pushing back against him as he fucks her hard, his balls slapping against her clit, making her whimper and beg for more as he uses her ass to improve her grades.
