I have a horny slave on the bed waiting for me to arrive. As he hears the sound of my stiletto heels, his cock is already throbbing. I tell him I'm going to give him some painful pleasure and he must obey my instructions. I caress his cock, and give his balls a good twist. He squeals and that pleases me, however I want him to feel real pain. So I get a ball vice, and with his balls between the wooden slats, I tighten them down with the screws. Of course, I leave a little tension for more discomfort on my slut. With his balls firmly secure and turning a nice shade of purple, I continue to tease him as I play with his throbbing cock. He desperately wants to cum, but I have warned him he must wait until I give him permission. As he moans even more, I get another vice and place it around his balls making them even more tightly squeezed. With his balls in a vice and aching, clearly my bitch is in pain. I so enjoy teasing him, as I place his throbbing cock between my silky stocking feet. As he begs me to cum, I get a little cup and place it on his chest. I tell him It's a surprise, and he will enjoy it. After some more teasing, my slut decides to suddenly cum without my permission. Luckily, I have his cup to hand and place it under His cock to catch all his cum. I want to punish him for his disobedience, so I order him to open his mouth and drink his cum. However, he seems to be having difficulty opening his mouth, I resolve the situation by tightening the vice on his balls. As my slut gasps in pain I easily pour his cum into his mouth. What a nice little treat for my bitch, as I leave him to digest his own mess.
