I purchased this giant electro butt plug called the Stanley. Nobody has been able to fit it, until today. Slave Tony is my guinea pig. The acrylic plug is conductive in four different areas to make his anus contract and pulse uncontrollably. I position the plug to shock directly on the prostate. I try different methods to see how much I can make his internal organs spasm out of his control. I decide that the slow, steady fuck to his ass looks the most interesting. The plug slowly sucks in and out of his ass uncontrollably. His prostate begins to make leak pre-cum. I am sure with time I could train him to orgasm with only anal stimulation via the electro plug.
