Blow to pop while I play with my pussy

I lay back in my chair and spread my legs and begin to rub my clit. i continue to give nice deep breaths and the balloon gets bigger and bigger. i hold the balloon between my legs and stretch the neck of the balloon to make sure that i blow this balloon up as big as possible! i know it is going to pop but i keep blowing deep breaths into the balloon until it pops! i giggle and jump a bit. i keep going playing with myself and its not long til i am orgasming!
