In this scene, these brazilian dommes have called slave Guilherme to serve them as a domestic slave. And they had the brilliant idea to use him to record for them a ballbusting video, to earn them money at the expense of his pain and humiliation! They start by holding him and kicking him in the balls, as they alternate. They also give him some hard knees, faceslaps him while spitting and in the second part of the movie, they cruelly stomp and trample his balls and cock, while laughing sadistically!
