Red
Series: Neon Genesis Evangelion
Sex factor: fairly high
Kink factor: f/f, rape, blood
This fic was once sent to me described as "the only true Evangelion lemon". True to the themes, characters, and disturbing nature of the show. And it's also one of very few hentai stories that I have maintained a personal copy of. The original link to it has gone dead - voila! I reproduce it here!
