When one wraps a zeppelin around their tits and said tits inflate to the size of watermelons. Then, their partner inserts an National Airship Association regulation air pump into their anal cavity and blows so much air into it that the clitoral region of said individual experiences such great levels of engorgement that it resembles a miniature zeppelin. Then their partner punches the inflated clitoris, releasing the built up air, while their partner screams "OH, THE HUMANITY!"
"Holy shit! Carol gave me such an intense balloon show I could have sworn that I was levitated several centimeters!"
