Are you still lightly stroking? You better be, I never told you to stop did I? Useless little man. Repeat after me "I live only to stroke for my Mistress." Keep repeating it while we do some edging.
When I tell you to edge you will grip My cock and stroke until you are seconds away from exploding and then you will release it and let it hang. Do this three times with a 1 minute break between each edge. Don't forget to repeat the phrase and don't take your eyes off of the tip of My cock.
You are just leaking precum now aren't you. We don't want any evidence hitting the floor. Make sure all your precum ends up in your mouth.
