The Window by Silver Shine is a fanfiction on Fanfiction.Net and let me tell that it is HANDS DOWN one of the best smut fics I've ever read, it is the best kakasaku fic I've ever read and it's the one of the BEST NARUTO FICS I've ever read too.

It sounds like I'm exaggerating but I'm not. The erotism is on point, and the buildup beforehand oh my god. Also i love how the author actually delves into Kakashi and Sakura's demons and how they help each other overcome it.

The story's just WONDERFUL.
