I've caught you hand humping again. I've already told you that pathetic little cocks like yours don't deserve a full hand.  I usually only allow you to use two fingers, but today you deserve a punishment.  You'll get a vibrator and use it ONLY on the tip of your cock during my stop and go game.  No stroking, no rubbing, only the smallest level of vibration on the head of your worthless little dick. No cumming until I say, and I'm not going to make it easy on you.  You'll want to cum when you see my tits flop out of this tight bra, but you'll be in for more punishment if you do!  Hold out until the end, and you'll get want you want... but you have to ruin it.
