We shall play a stroking game and whether you cum or not... remains to be seen.
Open up http://www.online-stopwatch.com/timer/1minute/ and http://a.bestmetronome.com/. You are going to follow the beats. Careful now, we wouldn't want an incident, do we? I would be most disappointed.
Let's start with 70 bpm to get you hard.
Continue when you are ready.
