Mia and Rae Exercise Their Lungs With Some Airship Balloons (MP4 – 1080p)

Mia and Rae try out a pair of Q646 airship balloons.  Each has to learn how to manage the back-pressure without a check valve, but they eventually get them both blown up.  Then they move on to the smaller but harder Q350, using check valves and puffing with all their might.
