Anal "exam"

"Alright Katie, we're done with the pelvic exam," you inform her as you pull your pants up. Some of your cum drips out of her pussy and lands on the exam table. "I'll need to flip you over, give me a second." You unlock the clamps and turn Katie over. You tell her to spread her limbs again. Soon, you have her locked into place, ass-up. You make sure to wipe her pussy clean of evidence with a towel before continuing. You take your gloved hand and insert a finger into her tight ass.

"Katie? Same thing here, I'll have to use something else to examine your..." You trail off.

"Fine," Katie sighs.

You take a 12-inch dildo and a bottle of lube out of the box you had earlier. "Katie, I'm going to use some lubricant to get the tool inside, ok? It might be cold," you warn her. You squirt some lube into your hands, and rub it all over her tight ass, making sure to get most of it near the hole. Then, you take the dildo and slowly plunge it inside of Katie.

"OH!" Katie exclaims as her asshole is penetrated for the first time.

"Katie!" you scold. "You can't yell like that, there are other patients here too." You take a ball-gag out of your box and put it on Katie so that she can't make a sound.

You remove the dildo and decide it's time for some real fun. You move a stool over to the exam table and stand on it, pulling your pants down. You ready your cock, and then thrust it inside of Katie, in, out, in, out. She shaking with each thrust, and you see her pussy get wet again. When you finally cum inside of her again, she relaxes. You pull up your pants and put the lube and dildo back in the box. You notice her panties and leggings on the floor, and stoop down to pick them up. You also grab her other clothes from under the table, and put them in a cabinet in the room.

"We're done with the anal exam," you tell Katie. You unlock the clasps and take the gag out of her mouth. She gasps for air, and blushes again. She still appears to have no idea that it was your dick instead of a medical tool inside of her.
