I have My slave right here, hands tied up. He know he will be subjected to pain. I could take a whip or another implement, but I want to show him that I don’t really need them. My dominant look will make him want to please Me. My bare hands will cause him pain that will satisfy My sadistic desires. Several slaps on his face will make him understand I am am very serious. I grab and twist his nipples hard and approach him, he can feel My accelerated by arousal breath. My proximity makes his dick hard, but I make him see that his pleasure is totally irrelevant, so I start to crush his balls in My hand, to stick My nails in his prick and ballsack, and to slap his cock hard. As I see him starting to suffer more and more, to scream harder, I get aroused more and more. I can see he understands and accepts that My pleasure is above all, as his prick remains hard despite all the pain he gets: he enjoys pleasing Me. Not that I care about his erection, the only good thing about it is that it’s easier to cause it pain. His prick and balls belong to Me anyway, he has no use for them except for peeing, and to offer Me the pleasure of torturing them.
