My goal was to hold my breath for 2:30 or longer and have an orgasm before I breathe. If I cum before the time is up I have to keep going. If I don't cum, then I don't get to breathe until I do. It's proof that I would rather cum than breathe and when it comes down to the line I choose orgasm. This is so so hard because I'm using so much oxygen trying to cum. You can hear and see my contractions as I push towards the finish line. My first attempt failed. 2nd attempt I came before the time was up and kept going another 10 seconds after the timer. My 3rd attempt I came and stopped right at about 2:30 It's such a turn on and very hard to do but when I cum it's so hard to stop and I want to keep going! I use duct tape for my mouth and put nose plugs on after my last breath. This helps as when you start having contractions it will almost make you to breathe. I hope you enjoy. I have longer ones coming in future updates
