Mistress Martina has a fetish for punishing slaves. She is always waiting for them to mess up so that she can punish them. She does not make it obvious for them and she pretends that she is doing it so that they can change and do things better. But deep down, she loves it when they mess up because it gives her a chance to punish them and try different punishment methods. Today she chose to pinch the slave's nipples and get a foot massage.
