After keeping my lingerie-clad sub hanging upside down for his first treatment, I kindly let him lay down on my Super Boomer bondage chair for his next dose of unrelenting, and frustrating, bondage, masturbation, denial and electrics. There are times when I have to accept that I can be the ‘Mistress of Overkill’ and this was just such an occasion as I pumped up the electric butt plug, pads and nipple clamps before leaving him for hours with his shaft steadily wanked by my insatiable Serious Kit milking machine.
