Ambitious Russian coed, eager to prove her academic prowess, offers her professor an unconventional form of extra credit. Sinking to her knees, she takes his thick, throbbing cock deep into her tight mouth, expertly swirling her tongue around the sensitive head. Her enthusiasm grows as she bobs her head, taking him deeper, until he's fucking her throat in a raw, hardcore doggy position. She gags and moans, but the thrill of being dominated fuels her hunger for more.
