This is the thing about rape fiction versus rape fact... in rape fiction the author often feels the need to add the crap about an orgasm during rape or real foced sex for sheer effect, and maybe to try to excuse the bloke committing the rape for his vile actions by making it seem she's liking it after all... In rape fact I don't believe very many women experience an orgasm, and if they did, it wouldn't be any kind of rape.
nc or non consent, is just a techie name for rape a rape fiction story board as a category ie 'the non-consent' section... There is no real life term under that banner nc, it's either forced sex or rape... and both mean the same thing... you get done for 'rape' when you're caught, not forced sex, or non-consent sex.
