Let me introduce you to your new addiction just by snapping my fingers. After watching it, this sound will live deep in your psyche, making you instantly hard whenever you hear it. The overwhelming need to send will make you leave any activity to watch it over and over again, until there's nothing left in your account. Feed me with your power. I guide the speed of your strokes during the whole video, and I reward your effort... or maybe trick you with doing it.
