I didn't realize it was possible to post lemon content on FF.net, I'm going to keep mine strictly to AO3 for now but that is surprising, I always thought it wasn't allowed there.
Suppose I should say that I mentioned I finished it earlier but I did actually upload that AsuKawoShin fic to my AO3 profile.
I also had a go at doing a KawoShin one too. Sort of ran with the idea of them going back to Kaworu's during ep 24 and him having a piano there and he and Shinji play the piano together before they go onto other things. Was fun to write. AsuShin is and will forever be my main pairing but I do enjoy fooling around with Kaworu from time to time.
