MIrror verse Kirk/McCoy fic

[luvmax1.livejournal.com]

I'm looking for a specific MU fic. Mirror Kirk abuses Mirror McCoy, and one time slices a mark into his skin with a knife. He likes it so much that he sends McCoy down to engineering, where Scotty permanently brands the mark onto his hip or thigh. I realize it's not much to go on, but if anyone has heard of it, I'd love to read it again. Thank you so much!

It sounds as Only in Empty Spaces (http://spikeface.livejournal.com/86963.html)
