15 minutes of real true extreme solo breath play, masturbating nude in heels only. I orgasm twice and only masturbate while I'm holding My breath. I put My hand over My mouth and plug My nose with My fingers, attempting to hold My breath past My limits every time. My face begins to turn red, I start to sweat profusely, My eyes roll back, and My body twitches. My body convulses in trying to find air! Each time that I finally take a breath, I'm gasping for oxygen. I cum while struggling to hold My breath, holding it even until after I've cum, until I really cant anymore.
