I begin by teasing your cock, knowing how much you love to worship my perfect body by tugging out a big wad in tribute.  But that won't be good enough today. I want you to push your stroke session to the limits.  I instruct you to stroke and edge as your cock twitches, eager to cum, before telling you to slide a finger into your asshole.  We start show, one finger at a time, all the while focusing on the sensation of your hand gliding up your cock.  Finally, I command you insert a second finger into your ass and milk your prostate, as you remove you hand completely from your dick.  If you want to cum so badly for me, you are going to have to do it by massaging your prostate only.  Remember the sensation of your hand on your cock, imagine that sensation is my mouth running up your shaft while I finger your ass, milking you to a gigantic, hands-free orgasm.
