Looking for a blueberry story

Hey, need some help finding a blueberry story for my friend. She can't remember the title or author, but remembers it being on a Yahoo inflation group

Basically it's about this couple and some woman's husband cheats on her, so in an act of revenge seduces him and then feeds him blueberry gum, plumping him up into a nice blueberry. She puts the blueberry gum in her own mouth first though and gives him a strip tease before shoving it into his mouth.

I personally don't ever remember coming a story like this and had a little look on the Web myself, though I haven't turned anything up.

Any help would be well appreciated.
