Beautiful schoolgirl kicks the slave's balls

Description: I had so much fun today! i decided to put on a schoolgirl outfit that i really like and also put on black tights with a hole you know where... i made my slave kneel in front of me and then i grabbed his hands so he couldn't fall and i was kicking his balls very hard. although he tried to defend himself, he failed.  after a few minutes, i let him lie down on the floor and i continued my cruel play. his balls were so sore!  at the end i decided to play with him for a while longer and i made him get down on his knees with his back to me while i kicked and squeezed his little nuts with all my might!
