No. It's implying rape, and it's obvious. And everyone in that thread reaching to say "No it isn't!" should be ashamed of themselves.
Besides the fact that Bayonetta is laying there, naked and attempting to cover herself, and shivering in humiliation (such a departure from her usual character that this alone should be obvious enough)...Like, I mean, it's infuriating. FOR HOW FUCKING LONG in American Pop Culture has a dude lying down next to a woman and smoking a cigarette NOT been code for "there was sex"? This isn't complex thinking. This isn't hard. And this doesn't require anyone to be a sultan of pop culture references to get it. IF YOU'VE SEEN PRACTICALLY ANY 80s/90s ROMANTIC COMEDY YOU'VE SEEN THIS. This is so blatant that I'm literally questioning the motives of anyone who tries to suggest this is something else more innocent.
But nooooo, it's not implying rape. I can't.
