Gia Derza, the Russian bombshell, is a natural at teaching. When her student's husband proves inadequate, she takes matters into her own hands, literally. She fingers her pussy, making it gush with wetness, then sucks her student's cock until he's rock hard. But the fun's just beginning. Gia bends over, offering her tight asshole to him. He slides in, filling her up, while she moans and begs for more. The husband watches, speechless, as Gia's big tits sway with each thrust. She cums hard, her body shaking, and he follows suit, pumping his load deep into her ass.
