A fan sent me some gifts, which ended up being some big balloons I've never had before! So I test one of each out! The first is a black 24-inch balloon. I inflate it by mouth until it starts to get tight. Then I sit on it and grind against it, then take off my shirt. I keep grinding against the balloon but accidentally pop it. Using my balloon pump, I inflate a 24-inch Unique, until it is necking just a bit then tie it. Then I inflate a 36-inch Unique until it feels tight, to see how big they get.
