O.o I was about to recommend some stories but then I realized... the only truly amazing stories I've found with MCR have been man/man. Usually I'm not all that in to those types of stories either but around here that seems to be the thing. There are some amazingly written ones but I wish I could find more MCR stories with original characters. If you find some please share. (:

These are the ones I check regularly. The others don't update as often or whatever it may be.

Mcrmywife's stories are amazing, she doesn't have anything new but I've read her complete ones and it's truly entertaining.
There are more. Look for one_33's account, it's my old one and I have a lot of favorites there though a lot are, unfortunately, unfinished. And you could read the previous reviews, they were very helpful.
