Double anal / vag fisting

A stunningly attractive, Russian mistress is teaching her slave a lesson in extreme fisting! She stretches her holes with four fingers and a butt plug, then the roles are reversed and she invites her slave to double fist her in both holes and see how its really done! Her well used ass and vagina swallow two fists simultaneously and her asshole prolapses and gapes with hard punch fisting penetrations!
