After a session, my personal submissive did very well, so I untie him and begin by telling him he gets an orgasm. He's very happy about this, obviously. He's especially happy that I'll be masturbating him. What a treat. However, I then tell him I'll also be using post orgasm sensations to my dominant advantage. Why not use my dominance to the fullest? Of course he still agrees. Over the course of several minutes I masturbate him, spitting on his cock and using oil as well. It's slippery and you can hear the fast paced stroking. I edge him several times because I know his cock better than even he does, and he will be wanting the biggest orgasm possible. That requires multiple builds. I'm so generous. I use counting and multiple paces to keep him edged until he can't hold it anymore. I allow him to cum his thin, watery cum.... and then proceed to continuously stroke him as his thighs tremble and he whimpers in pleasure and torment. It's a delectable reward for both of us post session and I leave, instructing him to shower and clean up. He's a good boy.
