Your opinion is at your pleasure.
She was, according to her story, kidnapped and granted leave only upon servicing the two gents.
She went to the apartment willingly. Bill told her she couldn't leave and when she tried to he stepped in front of her and locked the door. She said she wouldn't have sex with the two guys and then had sex with the black dude because she was "guilted" into it. There were two other men in the apartment that she could have asked for help from. Did she do that? She could have sat her ass there on the couch and refused to budge unless they moved her. Did she do that? She could have demanded to be let out of the apartment. Did she do that?
Basically what happened was he told her she was going to have sex with the two guys, she said no, he said yes, and off she went to have sex with them. Was it bad behavior on Bill's part? Yep. Was it rape? Not as described.
