Now that you are all relaxed, lets get back to "work" then. Keep stroking slowly. But apply as much pressure as necessary to reach the edge, only using slow strokes. And when you feel you are only 1 more stroke away make another half and let go. As I told you you can't come you'll have to stop any incoming orgasm.
Just grab your cock as tight as you can and put your thumb on that tiny little hole on top of your cock and apply pressure downwards so nothing can come out.
But I hope that this isn't necessary since I want you to control yourself.
So, take 4 deep breaths and hold the fifth again. This time I want you to reach two edges. Between those two edges tease your nipples. Count the seconds while you're doing that. Start stroking again when the urge has subsided..
After the second edge I want you to tease your nipples again but double the seconds.
You're totally under my control already. You may breath again. Now start stroking slowly again while you breath deeply for 60 seconds. Make sure each breath is as deep as it can be. Feel that blood rushing through your body. Let go off your cock again and again tease your nipples. Do that for 5 minutes, while you stare at me and thank me for taking control over you.. Then you may..
