She gasps again. "Do you want to do me in the ass. John?" She feels your rhythm falter.

She gasps again. "Do you want to do me in the ass. John?" She feels your rhythm falter and grins back at you. "I sure do, Karen, if the doctor doesn’t object," you say, bending over to kiss the young Chinese girl again. "If you would. Go ahead.” Andrea replies and Karen continues, “I don't let my very successful husband do it. It's just for you, John."

You kiss your doctor again and as your lips press together her tongue pushes into your mouth. After a few moments, your lips separate and Andrea gives you a knowing smile. She wants you to enjoy her patient however the patient wants.

You slide your penis out of her cunt and reach down and position the tip against her anus. It is a much less elaborate entrance into her, but all the more thrilling because this is the absolute pinnacle of her privacy. Her anus is what she will keep guarded even from her husband, and she offers it to you, the doctor’s assistent, freely.

Gently you press yourself against her. It takes a moment where you can feel her trying to relax until you begin to easily sink in. The texture of her anus is much more stimulating than her vagina. For such a simple entrance, the nerves in your penis register an incredible texture inside.
