OOOh that is making me hot seeing you stroke. I must resist being able to touch and fuck you. Don't worry about me I can control my urges. I'm more worried about you controling yours.
Roll your dice again. The same thing number is how many minutes. Are you getting close? Well when you do that's called an edge. When you reach that edge stop stroking and let go of your cock. Let it rest for how ever long you need then continue stroking.
