There are so many ways to inflict pain on the testicles but one of my favorites is the simple application of a thin piece of wood, bamboo, or silicone. Ball caning produces a thin, sharp pain that goes perfectly with erection and orgasm control. You're going to do this to yourself with my supervision, so you'll need anything that could be long and thin. If you're struggling for ideas, take the stick from your blinds! Now you'll stroke as I say, then deliver strikes at the intervals I indicate. The question is-- will the pain in your balls destroy your orgasm or make it more intense?
