Since I wasn't really interested in reading those stories, but just found it a curiosity, I only applied the filters on fanfiction.net (Lucy, Levy and the "pairing" checkbox).

But apparently that filter only checks whether the characters you put in are in any pairing in that story and not whether they are in a pairing with each other, since it spewed out a lot of stories with each of the two girls in romance with someone else, most times LucyXNatsu + LevyXGajeel (or [Natsu D., Lucy H.] [Levy M., Gajeel R.] as it is shown there).

Maybe applying the "without filters" for their respective males would narrow the results down.
