Liza Del Sierra, the busty brunette, sashays into her professor's office, her uniform barely containing her generous cleavage. She straddles him, her big tits pressing against his chest, and grinds her innocent high on his growing bulge. His hardness strains against his pants as she leans in for a kiss, her big boobs rubbing tantalizingly. Liza unzips him, revealing his throbbing cock, which she eagerly slides onto. She rides him hard, her big tits bouncing, as he groans, gripping her hips. The office fills with their moans and the sound of flesh slapping flesh.
