You don't deserve to have control over your dick, over your stroking. And that’s why I’m only going to let you stroke for 5 seconds at a time. Jerking for 5 seconds is enough to keep you horny, hard and submissive. Then you will just take your hand off and wait for me to let you stroke again. I want you to constantly feel frustrated of having to stop stroking when you are just getting going. Will I even let you have the pleasure of an orgasm at the end of the session? Soon you will find out, wanker!
