Look at his giant balls all tied up and stretched out! How could I not pain test my new massage toy on them? The massage ball is meant to get tough knots out of your neck and back, it really delivers quite the hard punch. The ball is very solid and heavy and the flexible handle provides lots of momentum and control for the user. It's actually a pretty mean thing to use on balls since there's no way to make the pain even across both balls at the same time :D Once I make my subby cum from the confusing, dual stimulation of these two different massagers, I then continue on with both, turning his pleasure into delightful suffering while I giggle my ass off at him! xo ;)
