DESCRIPTION.
Knees to the balls. Title says it all. Why talk more.
Two girls test the strength of a man. Sonia holds him, hands on his back, and Michelle knees his balls dozens of times. When he falls down to the floor in pain, they make him stand up again, to knee his balls more.

Her knees keep crushing his nuts, dozens of times.
A look at these beautiful goddesses eyes, and you'll have no time before she stamps her knees between your legs and you collapse in pain at her feet. Over and over again.
Her boots know the way home, for sure.
