JOI Pyramid Training

Have you heard of pyramid training? Its something that weightlifters do to train their stamina. I think the same concepts can be applied to your jerk off habits. I think you cum far too fast for my liking. So were going to train your cock. Ill give you a number of strokes to do, and as we go the number will increase. Each time you start a new number, youll have to start from the bottom of the pyramid and jerk your way back up to the top. Do you think you can do it? If you cant, youre just going to have to watch the video again.
