I've heard of many fetishes in my lifetime, but none as strange as this one. This link has movies and photo galleries of beautiful girls who like nothing better than blowing up, overinflating and bursting balloons. Apparently people get aroused during the process. In our house, when a balloon is burst, the kids cry and the dog craps on the floor! No arousals here :(
