How long can you go? (part 2)

How long can you go? (part 2) by fakename46

Yeah, I know that look.
You almost lost it.
I hope you didn't. If you get to the end, a whole world of fun and excitement will open to you thanks to my friends and I.
Here are the last instructions.
I want you to crank the metronome to about 126
for the rest of the video heres what you do.
Stroke to the beat, one long stroke from base to tip, nice and tight.
Do that for mmmmm 30 seconds.
Then, for the next 15seconds, I want you to double time it, two per beat, only stroking on your head.

DO NOT CUM! You're almost there. Once you're done you can hit next. Again, DO NOT CUM!
