I recently wrote a non-con fill here,( from John's POV too) so I understand exactly what you mean about not wanting to support rape culture or over-eroticism of rape. I just wanted to confirm that I think you handled it all very well. Keeping them both so well in character throughout really makes it work. As much as we are hesitant to assign these dark motives to characters we love, I think this gets to the heart of what rape is... how it usually isn't a maniac jumping out of the bushes, but someone you know, and maybe love, usually trust. John is very emotionally compromised, and I think you did a great job at extending his existing character flaws.
