Straddle Andy and double penetrate him

"Climb on!" Said the doctor and he helped lift me up so I was climb above the stirrups and wrap my legs around Andy's. The doctor took both our cocks and pressed then together as we both pushed our dicks into Andy's well stretched gash. He moaned as we both moved deeper into his warm wet hole, easily penetrating his loose sphincter. We were in up to the balls and Andy's lips were wide and inviting. More fluids erupted out from between our cocks, flowing from the opening and down the doctors large hairy thighs. Andy was licking the tip of the nurse's engourged cock head, lapping at the precum that oozed on to his tongue. "More!" He cried as we moved in and out. The doctor reached for another instrument on the rack next to him taking a big ribbed dildo, over ten inches long, in his hand, pouring on more lube. He angled the head between both our cocks and I felt the pressure squeezing between them as he guided it inside. Andy's hole peeled open further and he groaned loudly, stifled by the nurse's balls that he had pressed over his mouth. Andy's ass lips were protruding massively as we both moved in deeper, the ridges of the dildo stretching him wide. I had never seen a guys hole open so big before. Both me and the doctor had large cocks and with the sizeable dildo Andy must have been dilated at least six inches or so.
