Suck cock for permission to cum

You really love stroking your cock for me dont you... well we're changing things up today, if you want to cum.. which I know you really do.. that cock is already twitching.. you're going to have to learn to suck cock. While you're gliding your hand up and down your rock hard cock for me, you're going to open those lips and learn how to pleasure another cock at the same time, feeling the head of his cock sliding past your lips, gliding over your tongue and hitting the back of your throat, pleasuring every inch of his sock with your tongue, sucking away faster and faster until you can feel his cock pulsating in your mouth.. only then are you allowed to cum. Are you up the the challenge?
