An admitted nymphomaniac comes to the doctor with a big problem. Her husband loves to fuck - especially anal sex, but she thinks it hurts. The doctor promises that he will teach her how to fuck. His sexual instruction is always "hands-on", and when he puts his hands to work on this BBW housewife, she can't resist his expert attention. He warms up her ass with an enema, and soon replaces that with his own cock inside her anal alley. She leaves his office with her asshole stretched and tingling from the anal orgasms he gave her. Yet another satisfied mom.
