Electrosex Blowjob
Sometimes he’s in the mood, sometimes he’s not. This time he was. His masochist came out to play. At my request he wore sexy disposable clothing and after I tied him up over a spanking bench, I slowly cut off his clothes and bit, licked, spanked and caned each body part that I exposed. And that was just his warm up.
Later I had him on the bondage bed (we were at The Wet Spot after hours.) After beating his ass with his least favorite toy, I turned him over and played with his cock, wrapping it in his favorite leather cock ring and attaching it to my tens unit. Every time I turned up the tens unit he jumped and I sucked and kissed his cock. Pretty soon his pain and pleasure responses became all jumbled up. :) This got me super horny, so I climbed on top of him and he gave me a great orgasm while I continued to torture his penis.
