Lets move this along quickly. You should be stroking after your break remember...
This part will be difficult but satisfying.
Here is another visual aid.

I want you to start stroking slowly, trust me it's in your best interrest to start slow. Once the two beautiful women start to explore each other I want you to speed up and reach an edge. Take a 15 second break and edge again.
Repeat the 15 second cycle through the rest of the video.
I know it's going to be a huge workout.
Once the video is finished take a 30 second break the proceed.
