That's enough, now let it go and show me just how hard your sorry little dick is.
Mmm, it's been a while since I let you cum hasn't it? Those balls look pretty full.
I want you to give them a squeeze for me, and then another (harder) one.
That's it, we want those little balls nice and full so that when you finally earn a release you've got plenty of hot, creamy cum to slurp up and swallow.
Now give me another thirty strokes and be quick about it.
