This was one of my first guys that liked to play with electricity. I had never even heard of a tens machine until we started playing.  I quickly learned all the fun things that electricity has to offer though and really enjoyed hearing him beg for mercy.  I spent many an hour lightening up his cock and balls. I even got to play with a butt plug insert so that he really started to plead good. I would laugh so hard my cheeks would hurt. Unfortunately or maybe fortunately his life changed and he got remarried so we no get to play like we used to.
