Stuffmybelly has asked me on Discord that question and here is why.

I find bursting arousing or funny, because I like to see any inflatee popped no matter how it happens. In sequences this fetish is a continuation of an over-inflated characters or the alternate ending of it.
In my prefence I rather aim safe balloon pops with staying alive, but it doesn't mean I will go exactly for that type. It's ok for me to see any way of explosion, even if it grosses me out.
