Stella knows her ballboy was scared of this one , she's been working out her legs for the sole purpose of ballbusting! She starts off with a devastating knee , sending him straight to the ground. Stella then tells him to get back up and countless knees ensue. Stella kicks his nuts relentlessly with a giant smile on her face, and laughs the entire clip! Knees, kicks, stomping, squeezing , the list goes on. Stella even made him kiss her right knee at the end because it was so red... LOL.

HARD ball busting.
