When a Slammy (SlamWhore,Slampig,Original Cowgirl,or ButtHole Whore) Is mounted in the fetile position while sitting on top of an O.S. (Original Scumbag/Male) with his Hammer of a Dong in her snatch, while another O.S. is behind her fully erect and ready to go and slams his RamRod right in the Slammies rectum.

Double Peneatration the Scummy way.
O.S.#1:"Damn Slammy the way you ride my Sledge is Slamtastic!, You deserve a surprise gift would you like one you dirty girl?"
Slammy:"Ofcourse I would love a surprise aslong it has something to do with your Big Bold Dong!"

Slammy:AAAAAAAAAA!!!
O.S.#2:"Pass the Jack while I slam my cockasaurus in her crack"
