Sitpopping is sexy. And sometimes it's too fast to enjoy. There're some ways to prolong it and the most obvious one is to be gentle with balloons...at least at first. To increase the amplitude slowly. To take the balloon to it's limit step by step. That's a very special thing - in some point I can literally feel that limit of balloon and could keep it below it...or take it beyond! There three Tuftex 17'' were the ones that tasted the entire way from gentle pressure of my butt to the final burst.
