I recently began boxing as part of my fitness routine. Rather than using a boring punching bag or speed bag I found that using a slave in bondage with rock hard cock and balls can be far more interesting. Wearing my tiny workout bra short and Everlast gloves I deliver a variety of jabs and upper cuts to break in this useless excercise prop as my warm up. Despite his groans I take my gloves off and grip his balls, kick him while in my runners and finish off with super fast continual punches until I break out in a sweat. What a great workout:)
