The doctor needs to be *really* fucked

Evelyn stepped away for a moment to rummage in her black bag. I found it very hard to split my attention between the woman thrusting herself against my erect member and the developing situation with the nurse. However it did not escape my notice when the nurse pulled a long green dildo and a black nylon harness from her bag. She stepped back over to the examination table and said:

"Be a dear and stop for a second Sarah. The stud needs to see his filly getting really filled."

The doctor let out a small moan and eased all the way down on my penis, completely engulfing it. I watched as the nurse began wrapping the harness around her waist. She then sucked wetly on the dildo, licking its length in an exaggerated manner. When she withdrew it from her mouth, it was coated in saliva. The fake cock slipped into the harness, pointing lewdly from her midsection. Finally, the nurse dribbled lube along it's shiny length and said:

"Be sure to watch this John."

She put a hand on the doctor's stomach and held the dildo in her other hand. I was mesmerized as I watched the thick plastic **** its way into the doctor's ass. She made noises that were a mixture of pleasure and pain. I could feel the dildo pressing against the thin wall separating my penis from the doctor's rectum.

'Fuck him like you mean it," Evelyn said in the doctor's ear, beginning to thrust slowly.

Sarah let out a moan as she began to rise again, my cock and the dildo sliding in and out of her orifices.
