Tomato Juice Inflation Story?

Does anyone happen to know the author of a story that was written a few years ago (or by chance where one could find the story)?

The story revolves around a girl, standing in the middle of a room, whose body turns red and begins to fill with tomato juice. During the inflation, a random woman comes in to chart her inflation. As the Tomato Girl reaches her inflation peak, the Observing Woman begins to help the girl deflate...in various (erotic) ways.

Does anyone have any idea what story I'm talking about and where I might find it?
