I'm going to be very mean to your dick, just to rub in how little I care about it and your pleasure. It's just a tool for my use. Even though you know this is going to be difficult, you're still going to stroke and obey. That's the most amusing part. Knowing I'm going to be mean to you makes you even more excited. Now you get to show me how you'll suffer for me, how you need me, and crave to obey my jerk off commands no matter how cruel I am to you.
