Re-edited old, but very good, clip.
Yvonne is in a bad mood, means she's dangerous.
She tramples her slave wearing sneakers, she's brutal not careeing on what and how hard she steps/stomps/jumps, this makes him crying, louder is better = more pain is better.
In the middle of the clip, she binds his hands on a radiator, no he's more helpless.
She jumps on his groin-area, she kicks right in his balls... much noise from him.... makes fun!!!
Incredible, how brutal a young girl can be!
