Oh, wow. I'll be honest. It's too much for me. :) Seems, I've got limits after all.
Kudos to you for your bravery in going for it, though. Honestly. The execution is wonderful. If extreme chan was a kink of mine, I'd be in heaven. I do love Fenrir/Draco so much. And it's really made me think about limits and how they differ from person to person. Whilst this makes me feel extremely uncomfortable, I've written things which are equally as dark and extreme--just geared more towards my personal comfort levels and kinks.
I don't feel this glorifies or eroticises REAL LIFE sexual abuse of children in any way at all. They are both fictional characters, and the situation is entirely fantasy oriented. It's porn--not a social statement. If it was a photograph, I'd want to cry and throw up. But the fact is, it's only lines on paper.
God forbid the wrong person should ignore the warnings. I can only imagine how upsetting that would be. But the warnings seem pretty clear to me. Although it's not for me, I'm glad there's still space for it in fandom.
