Dr. Cumowitz had to call you in for a follow-up to your last exam. You need to give a bigger cum sample this time. After my latex exam gloves are on you are brought into the room and strapped in. I need to make sure your dick is extra hard and you're turned on enough to give a nice big sample. I tease you by playing with your cock, having you watch me curl my hair, and licking off your precum. I stick my lubed fingers in your ass to fully milk your prostate. You end up not giving me a big enough sample and I have to milk you an extra time. This time I come into the room wearing a PVC bodysuit, thigh high boots, and my strap-on. Your final sample needs to be pegged out of you.
