#not rape

I was just reading this book (ex superheroes 2) and the main character is being threatened with rape by the female supervillain if he doesn't have sex with her. He doesn't want to be raped I guess so he consents to sex but he proceeds to hate fuck the supervillain.

I thought I knew where the line between rape and not rape is, but this scene in the book made me reconsider. Was the main character raped or not?
