Sorry, boy, but you know I can't let you! If I just gave you everything you wanted, you'd be nothing but a no-brains jerkaholic. Take that condom and put it on our cock. I hope you chose a nice brightly colored one, to make our cock look extra cute!
You see, playing with our cock is like dessert. You can't eat a whole chocolate cake at once, otherwise you'll turn into a greedy gross fat-ass slob. But if you eat a little slice, one bite at a time, and savor it, you can have a rewarding experience every so often and stay nice and healthy! And the fact that you're not stuffing your ugly face with cake all the time will make you enjoy each slice as a special treat!
Do you understand? Tell me you do. Say "Thank you Miss Alexandra, now I understand that I can't just jerk our cock as hard as I want all the time because it will make me a loser stroker addict." There you go.
Now start gently stroking our nicely wrapped up cock. I know it probably doesn't feel as good as before, but remember what we just talked about. Build up the speed and intensity until you get our cock to the edge, and hold it as you continue.
