I blow to pop a 16-inch then a 17-inch balloon, which both get quite big! Then I blow up and tie a 16-inch and a 17-inch balloon, which are both huge and suprisingly did not pop as I was tying them. Then I blow up and tie two 12-inch balloons while riding a dildo, then blow up and accidentally pop a 17-inch while riding the dildo. Then I sit to pop one of the 12-inch balloons I inflated.
