@bbwolf:

I can't say anything about Powerone's story, I had to read it first.

But I think your view towards non/consensuality is somewhat limited:
Hell, 70 % of literature is based on non-consensual phantasies and story-lines:
Or do you think, the victim in an Agatha-Christie-mystery-novel likes to be murdered?
Or what would you say to one of the biggest virtual mass-murderers of all times: William Shakespeare?

A story-writer doesn't have to care for imbalanced minds, who want to copy the fiction in reality.
Otherwise a "Superman"-artist would be responsible for every idiot, who jumps off the roof thinking he is from Krypton.

Even real consensual BDSM-relationships are often based on non-consensual fantasies.
A couple engaged in a BDSM-play isn't stopped by non-consensual talk like "pity, pity, I can't take it anymore". No, they fix a code-word before the session to obtain the fiction of non-consensuality as long as possible.

One of the main principles of fiction is:
You can hurt people all you want, because they don't exist. Why should there be other rules for BDSM-fiction?
