I'll make you burst! Balloon fetish!

Today I want to let you burst really hard, like my balloon here. Little by little I'll blow it up for you, rub it against my underwear, against my hot, shiny pussy until it's really plump. Wouldn't you love to be in its place between my thighs? The tension rises, not only in the balloon, but also in my trousers ;). So do you want to know how huge it has become?
