TLJ: Punish him every time he cums

From Create Your Own Story

“Let’s play a little game. It would be a shame to waste your erection, but you can’t have anything nice, not with me. I will make you cum again and again, but each time you do, I will use this on you.” You explain, striking the air with a long whip with durasteel tips. The traitor buckles against his chains, but his fate is sealed. You can’t wait to draw blood, but can’t deny you want to see this nice dick in action, as you slowly stroke it with your left hand, keeping it hard and ready.

How do you make him cum?
