Awww, that's too bad. Looks like our time together is up and it's time for you to move on to see the next COSTUME girl. I want you to leave your balls tied up. I know the other girls will like that.
But before you go, I want you to stare at my pussy and stroke your cock. I want to see you BURN with a little more pain before you leave me.
Take your free hand and place it flat under your balls so that your balls are lifted up closer to the base of your cock. If you're doing it right, you should be hitting your balls on each downstroke. You can stroke as slow or fast as you want, but you must EDGE this way before you can continue
