She'll suck up to you to avoid it. She'll promise you anything. She'll be a proper little slave slut, meek and obedient. But you can't let that soften you or change your plans. Every slut needs to find out what she thinks her limits are. And it's your job to push her past them. To remind her of your power. And of her absolute submission to you.

When it's time to introduce a little pain training into your routine, go slowly, but go firmly. I started off by handcuffing my naked slut wife to a steel pole in our basement, her arms behind her, on her knees on the rough, concrete floor. She was so helpless I had to take a few minutes to force my finger into her cunt and slide my cock into her waiting mouth. Then it was time for the main event. Taking each nipple between a thumb and forefinger, I squeezed until she winced. I twisted until she gasped. I pulled until she whimpered. And then I did it again and again, allowing her begging to wash over me even as the feeling of power inside me grew and grew. Every time she pleaded with me to stop, I tortured her tits all the more, pulling at the soft flesh until red abrasions appeared. She searched her mind for whatever she could promise that might stop the pain. She would be my permanent ass slave. She would be a gangbang slut for my friends. She would star in a porno that would be uploaded on the web. And still I slapped, twisted, pinched, pulled and abused her tits.

Finally, when her jugs were red and raw, I had some "mercy" on her. With a few ice cubes, I covered her tits in cold water, replacing one kind of pain with another.  Then came Step 3. She tried to twist away when I pulled out the clothespins. But the promise of a long and painful spanking stilled her protests. As I attached a clothespin to each of her swollen nipples, her gasps made me hard. Once they were on, though, I think she realized that they didn't hurt as much as she expected. She'd passed her first pain test. 

Now I give her a good pain treatment every couple of weeks or so. It's a good way to mix things up and keep my dominance imaginative. For her birthday, I dripped wax onto her tits and pussy, leaving a nice trail of hot wax all over her body. I've got a nice set of nipple clips, which I like to make her wear under her clothes out in public. And I've found that certain park benches are the perfect height to serve as wooden horses, which I force her to ride to entertain the old men and other slave owners. I think it's those days of pain and humiliation that make her appreciate the other days, when she's nothing more than a cheap sex slut.
