Medical Ejaculation Assessment

As a professional, conservative sex part of what I do is physically check that everything is working properly. A "systems check" so-to-speak. Today my patient is nervous as I ask him to strip naked & answer some personal questions about his masturbation habits, his fetishes, his sex life, etc. I eventually get him to admit he has a fetish for licking pussy & ass. He's just crazy for women's rear-ends. I tell him to close his eyes while I'm stroking him & imagine that I'm sitting on his face...he has vivid visions of my pussy & ass against his lips...he ejaculates enthusiastically by my latex-gloved hand.
