You are jerking it kind of close to me again, Master. You look like you might cum, Master.
No! I mean whatever you want Master, but I don't deserve to see you cum.
Just keep stroking your cock please, Master. I'm such a worthless slave, I don't deserve to watch you make a beautiful cum on me. Please, let me watch you stroke for another minute. I'll tell you anything you want, Master. I'll be a good slave.
Jack off for just one more minute, Master. You wont regret it.
