Wow you really like that don't you. I know most of the time I make you play with yourself, but tonight you can't do that now can you?
Just sit there and feel my hand stroking you. I could grab it harder and stroke faster like this. Stimulating the head really gets you close fast doesn't it! With you sitting with your balls hanging down, I can see them rise up as you get closer.
You will learn tonight that those balls will betray you. Let me bring you right to the edge now. There.... feel good? I will stop just before you cum. We have to wait since this is going to be a very very long night for you!
