A little oldie from a site I used to frequent before I started posting stories on FA. Writing.com can be a cool place but sometimes teenagers with lust addled minds end up ruining cool storylines from the Interactive Stories section, but sometimes good plots come out of those including this one.

Basically a Digimon fanfic that explores Expansion fetish and happens to have a pretty lengthy Foot Expansion plotline. Wish interactive stories were more popular these days, I really like doing those when there are others willing to follow up with good additions instead of the usual "she haz secks and stuffz" chapters.
