I blow to pop three 14-inch belbals sitting by my mirror (a Balloon Ace tattoo logo print, a yellow, and a purple). I have a bit of a rough time with the last two, as my hands got a little sweaty so my fingers would slide off when the necks tightened! I managed to work past this though, and pop each one with the power of my lungs. I am wearing a gemstone buttplug in this clip, which you can see poke out of my butt just a little as I'm blowing the balloons sometimes.
