This is a test of your patience and obedience. The rules of the game are simple: stroke and pump all you want in order to cum, but you must stop when the screen goes black. You'll be challenged to stop and wait for just a few seconds or a whole couple minutes at a time, so you're not allowed to pause, fast forward, or rewind. Will you be able to maintain yourself enough to cum before the screen goes black again, or will you accidentally ruin yourself or not cum at all?
