Hot little 19 year-old Anastasia just finished serving Dr. Mercies at his fucked-up anal banquet. But he wasn't done with her. He returned to her cell to use her again--roughly and crudely. She remembered her name ("Little Piece of Dirt on the Floor") and was very obedient. He fucked her face and ass for a long time, then decided to reward her by letting her cum. The trick was she had to cum with her tongue in his ass... and then again with his cum dripping down her chin. She came hard several times, and then he left her there as she thanked him. Actually, she thanked him repeatedly throughout the scene. What a good girl she is. A filthy, submissive slut willing to earn her orgasms.
