My slave-friend doesn't have a good pain resistance yet (or at least not good enough for me), so I decide to enroll him in a high intensive balls resistance training. I start educating his balls shoeless, in white socks, stomping and squashing them on the bench. Here I let him kiss and lick them because I'm a gentle mistress after all. I then put on my beautiful flat boots, for a very fun and comfortable ballbusting. I try stomping with my heels and squashing with my foot tips, hard squeezing them from time to time in order to relax a bit ???? Still because I'm gentle, after more than 10 minutes of boots torments I let him take off them and worship and lick my beautiful small feet in stockings ???? I then remove his balls last (weak) protection: his pants. Now they are bare, sore and very sensitive targets for my cruel carings. Aside from stomps and squeezing (never enough with these), I also lavish good hard slaps to those balls, to the point of making him squealing strange feminine cries XD Very thorough ballbusting in this clip guys, enjoy!
