Your mother tried her best to help you with your disorder: Massive Penism. But it didn't seem to work! The doctor who consulted with your PCP to get a diagnosis was gracious enough to make a house call to see if she could help, and when she arrives, your massive strains immediately upon seeing her. You're a sucker for big tits and a nice ass, and when she starts asking questions about whether you and mommy have tried anal, there's no holding your cock back. She happily notices the straining member threatening to break through your jeans and pulls out a butt plug, pushing it into her ass while she cheerily tells you that she'll be taking your cock deep into her asshole to treat you. You can't believe how lucky you are! Sure, you're a medical oddity, a physical freak, but who wouldn't want to see a hot doctor with a cock buried in her ass??
