“So! You want to extend your strength, your stamina, and your ability, with extended breath play? Then play along, no cheating.” And Coach Marx doesn’t like quitters. Also, some super fun face-sitting. “You have lots of oxygen, don’t worry, reach for your cock.” About as good as breath-play gets. A lovely client, who gets it, and puts themselves truly in my hands. I may start chanting “no more air for you” in a hot voice. Brutal climax.
