Brilliant little position.
My wrists are cuffed to my collar. The vibrator is taped to a wooden pole. I am impaled on the pole and the vibrator is humming against my clit. A little push on the end of the pole and it goes deeper into me and pushes the vibrator harder against my clit. Sometimes he spends forever not letting me orgasm. Other times its orgasm after orgasm until I just want them to stop. :)
