Ginger Blows Single and Double-Stuffed Sempertex 18's to Bursting (MP4 - 1080p)

Description: Ginger huffs and puffs mightily to blow a thick sempertex 18" round balloon to bursting, managing the considerable back-pressure without a check valve.  she even decides to start the double-stuffed test without the check valve, and manages to produce over 2psi to begin its expansion, but soon re-considers that decision,  she deftly removes her mouthpiece, snaps on the check valve, and then re-attaches the mouthpiece, and begins puffing away.  her lungs and cheeks get quite a workout, but manages to prevail.
