Slave challenge

This bitches here think that they are worth to be Our slaves. We have only one place free for personal slave and We have to choose between them. But they really have the potential to be? Do they have the goose on? With only one post free they really have to prove themselves, they have to impress all 3 of Us. They will pass several tests until We can choose who is the winner; who is the lucky one to remain in Our presence. We will kick their balls, whip them, make them pull hard from their balls and if they do well they will get the chance to kiss Our boots and feet. Now let's get to work. Prove yourself.
