Robbi Racks has a problem with cocks, so when she goes to see Dr. Carl for advice, he knows just what to prescribe her... more cock! Doctor Carl's cock, to be specific! He gives it to Robbi up her ass and every which way so that she's moaning in pleasure and begging for more right up until she cums right in Carl's mouth. Robbi then moans in ecstasy as Carl splatters his jizz all over her big titties.
