AeriSeph by Time Loop!
I recently got over this,a 20 pages long Aerith/Sephiroth doujinshi by the circle Time Loop (2008). For being a doujinshi with a quality you can make out of your own printer at home, it was awful expensive, but I couldn't just resist, doujinshi with rare and intresting pairings doesn't usually come around that often!
Author's notes...
Middle.
And final snuggle ^_____^
They're pretty sweet when considering that they're called a "crack" pairing among some ff7 fans, but originally they were actually meant to be lovers (or siblings...) :P
Good thing fanficton exists!<3
