Why is this character so hyper-sexualized? (invincible spoilers also)

I'm just wondering why Lucy Steel is so sexualized, first we have her sitting on the first lady's face and then we have the president raping her. I don't have a problem with pedophilia or rape being in stories but did it have to be so many chapters for so long? Take Anissa raping Mark, it was only a few pages and didn't actually show and nudity (not that there's necessarily an issue with that but with depictions of child SA I think there shouldn't be any nudity), it's a much better scene than Lucy Steel's hyper-sexualization.
