You are in for your annual medical exam. You are all healthy! But there is one last test I must administer. Please get naked. Don't be shy, I am a medical professional. You will have to show me that you can climax naturally. You cannot believe the words you are hearing, but your cock is throbbing. I sweetly encourage you to stroke your cock. I even strip down to my lacy bra and panties and jerk you off too. I grind my ass on your cock and you can feel yourself being washed away in pleasure. You don't want this moment to end! You cum so hard for me in my clinic. Just as I suspected, you are perfectly healthy and horny.
