The best clip Ever. Actually it's a double flying ball-kick. Mistress Seva, wearing head-to-toe leather, is lined up between two of Her slaves who are restrained in spreader bars with their legs wide open & vulnerable, & she is swinging back & forth getting a running start at crashing into their balls with Her brutal boots. you can hear Her boots running across the floor before She flies into the air across the room & into their balls, over & over again. At one point, one slave is down & only one is left to take the massive, struggling back up again & again until he is down for the count
