Quick and efficient

You run to the bathroom, your pants already down by the time you've arrived. You begin tugging away at your member, knowing time is short. Luckily, your mind is well primed and you are quickly approaching orgasm within a few more strokes.

You surprise yourself with how quickly you begin to pump a small and desperate stream of cum into the toilet. You don't sense full satisfaction, feeling you might have rushed too quickly to the finish line. You flush the toilet, and contemplate a second act, wondering if you have the stamina to achieve such an act.
