Granny works as a sex therapist and occasionally she'll be presented with a problem that is easiest helped with some physical exercises or demonstrations. When the client is a fit, young black guy with a great big cock, it doesn't seem to matter what the problem is, Granny is gonna find a way of getting on it. This guy worked in porn and got to fuck lots of hot chicks every day, so when he's was out and about in the normal world, he wasn't finding normal women attractive and it was affecting his social & sex life. Granny decides to show him just how horny older, plainer women can be and by the time she's finished with his 'therapy' he seems to have no problems whatsoever
