This is one of my favourite stories ever... it's short and sweet, ends wonderfully and is full of great description. It's one of the earliest stories I remember reading on this site back in the day, but no-one's ever put a name to it.

I agree it's a great story, and I too would like to credit the author. Is this an earlier version of "Balloon's End"? Not only are the stories extremely similar, using a lot of the same dialogue, but at one point in "Balloon's End," the female character, Susan, is mistakenly called Rebecca, which is the name of the woman in "The Bloating."
I'd also like to know if the writers of "The Challenge" and "Games" have come out of the closet yet. The latter is one of the best inflation-torture stories I've ever read.
I want to pop so much I could burst!
