Sadistic milking - (Two ruined orgasms and post cum torture) pregnant

This dirty jerk got my sister pregnant one year ago and I m still not donepunishing him for it. As he sits naked and tied to a chair, I drive himcrazy by stroking his cock but refusing to let him cum. With his mouthgagged he breathes heavily as I jerk him off, using my spit as lube whilerunning my hand up and down his big, hard cock. All he wants to do is cumbut I won t let him, choosing instead to make him suffer as he sits withaching balls. I bring him to the brink of exploding only to leave himhanging and when I finally do let him cum I ruin his orgasm by refusing totouch his cock while he spits his jizz all over himself. I immediatelybegin tugging his cock again while he groans in discomfort, milking thisbastard hard and fast until he cums yet again, his cock and ballsscreaming in pain as I tug them raw. Two ruined orgasms for this filthyslave! I leave him tied up for his cum to dry all over him.
