I Own Your Oxygen

Take a deep breath and hold it. How long can you keep it in for me, with your lips sealed and eyes beginning to bulge? Im going to push you to hold it for longer and longer, starting with 1 minute and going up to 2 and a half. Ill also intersperse some ball slapping instructions for an extra challenge. Let me hear those sweet smacks! If you can and make it all the way through the last hold, Ill let you cum at the end! Otherwise, youll have to ruin it.
