I'm slightly disappointed that I can't ship this. Levy has to be with Gajeel. Lucy doesn't matter as much for me, but Levy has to be with Gajeel. No matter what. Levy x Gajeel, with Levy as the top. It's one of my few het ships.
There's actually a dozen or so Fan fic for Erza X Lucy - tho no great ones - that's about the only yuri I ship in Fairy tail - and I like the idea of Erza X Wendy for some reason lol - There's no subtext for either in the show but still..
