Easy but Difficult
Now you need to open http://www.metronomeonline.com/
Now for the challenge:
You need to select a speed on the metronome that you want to stroke and cum to - Yes thats right - You will be cumming. You must stroke to the same speed of the metronome and cant speed up or slow down. Sounds simple right?
Once you start cumming, you must start the 2 minute countdown timer and continue stroking at the same speed to the metronome for 2 minutes. The challenge is not to stop and not to slow down. Can you do it?
Its your choice if you use lube. There is no warmup allowed which makes this tease more difficult. You must pick 1 speed you want to cum to, and continue stroking to once cumming.
If you choose a faster speed, it will be easier to cum, but more difficult to continue stroking once cumming. If you choose a slower speed, it may be difficult to cum at all. Perhaps you should choose a medium speed - the choice is yours...
Have a play around now with the different metronome speeds and choose the speed you wish to stroke, cum and continue stroking to.
