I often get complimented on my legs and their nice definition, long muscles and feminine shape. I get asked if I go to the gym. Guys, come on. I don't have to go to the gym. If you are into ball busting like me on almost a daily basis, that will suffice. I often admit that ball-busting is my cardio. I prefer longer sessions, anything over 10 minutes is ideal. It gets my heart rate up and I kick and kick and kick. Uaaah! Practice makes perfect too. It makes me feel great that while I do something for my health and beauty, slave is suffering and I put him in tremendous danger. See? A win-win situation. Here I served him 250 kicks into his sacking balls and boner cock. Check, cardio exercise for today completed. slave on the grounds, bonus points. Yep, that makes me happy!
