I blow to pop 4 14-inch Belbals side by side, blowing one breath into each one at a time. They all pop right around the same time, but which one first? The excitement of the four pops one after the other gets me very aroused but was not quite enough for me...luckily I had two more 14-inch Belbals on my bed, overinflated and clipped. I unclip one and blow to pop it as I grind on the other, cumming on it when I pop the fifth balloon. Then I unclip the last Belbal, and test just how much more air it can handle.
