I'm normally a big defender of erotic content in otherwise non erotic fiction. Enjoying this kind of content is incredibly human and if you were to definite which part is a social construct, it's deliberate inclusion or deliberate omission, clearly the latter is routed in something more artificial, in my opinion.

That being said, this panel is a lame. The cropped framing is particularly objectifying, and it feels very unnecessary, like it's just here to have an ass in shot. It's literally a pulp thirsty trap so people who see this page are interested in the comic.
