Tough Nipple Torture

The puffies of my slave will suffer more than they have ever suffered before. Very first I pinch them to warm up my slave. But he doesnt know whats I grab my very first implement, pinching his puffies with pliers. The slave screams louder and louder, but I do not let him off so easily and continue with the next tool. I squeeze his nipple really hard hard in an adjustable wrench, screwing it tightly. I love to see how much this nasty pain torments my slave. Finally, I decide to treat his very sensitive nipples well - I use pointed pliers to complete the torture!
