Katrin and her human punching-ball

Beschreibung: Katrin uses her slave for improve her boxing-skills , but her slave is impudent and tries to defend and fight back, This isn't Katrin's way, she shoves him to the grounnd and, once on top, he gets his lesson. Kneeling on his chest or sitting on his face and everytime hitting him with her boxing-gloves. A little more than only play-fight! Katrin wants to win........
