In "Cocksucking 101," a dirty-minded vixen learns the art of deepthroating. Her lesson begins with a self-indulgent pussy-fingering session, her juices flowing freely. Her instructor, a hung stud, watches, his cock throbbing. When she takes him in her mouth, she's eager to please, gagging and gasping as he pounds her throat, leaving her face glazed with spit and cum.
