Interruption

She surprises you. She stops sucking you and grips the base of your cock to retard your orgasm. She wipes the saliva from her lips with her free hand and waits to let your level of excitement recede.

Just then, there is a quick knock on the door and the nurse enters. "Doctor, can you...." she stops in her tracks and stares at the scene she interrupted. She quickly closes the door behind her and a smile steals across her face. "Well, John, I thought this was to be a 'quick check up', but it looks like a more thorough 'treatment'!"

She and the doctor laugh and she crosses to stand next to you. The doctor releases her grip and her place is taken by the nurse, who wastes no time in getting you into her mouth. She is as good as the doc and adds some finger action to your ass. The realization that she isn't wearing a rubber glove drifts absurdly through your mind.

Behind you the paper covering the table crinkles. The nurse pops her mouth off you and leans to look. "The doctor is ready for you now, Mr. Doe." she says with a grin.

Turning you see that the doctor is indeed very ready. She has stripped out of her skirt and panties. She is on her back on the table and her feet are in the gyno stirrups. Her pussy is gaping open and oozing wonderful smelling juices.
