Leçon d’anatomie anale

Tiffany's tutoring session with her pervy instructor is going nowhere fast, and it doesn't help matters when she picks up a book called 'The Handjob Handbook.' Tiffany is supposed to be studying for her biology midterm, but instead she gets a lesson in human anatomy when she puts this guy's fat cock in her mouth. If Tiffany studied as diligently as she sucks cock, she'd be a valedictorian.
