Kinda ruined it with the whole violent rape into submission angle. The original stories were much hotter when it was implied she fell for the Ugly Bastard in a more normal way. It just makes it hotter if the girl in an NTR work actively chooses to be with the other guy instead of being forced/raped/drugged/blackmailed into it.
It's the same deal with "Ride Your Nightmare", the original story of the MC not knowing his 2 best friends were fuckbuddies was fantastic, but then the prequel had the guy friend blackmail the girl into being his sex slave.
