I don't think she looks inhuman. In fact, all she's done is increase the very human factors that heterosexual males are naturally attuned to for various evolutionary reasons. She is the McDonald's fries of female anatomy. We love them because they're fatty and salty, which in days of sparser food, our bodies learned to love. She has big boobs, hips, and smooth skin. These ARE attractive features, and it's not our society necessarily. It's our genes. I'm not going to apologize for finding those things attractive, and frankly I'm sick of constantly being told I should. None of that is to say that being attracted to her is good for her or us, just like the McDonald's fries. But you shouldn't feel horrible about your life or your culture for finding her attractive.
As a side note: does it objectify a woman to look at her that way? Yep. Is that a bad thing? Well, no, unless you're blind or know how to violate causality and get to know a woman personally before perceiving her as an object. Especially when she's a static set of internet pictures. We all objectify each other. It's when that is the extent of your perception of another human being that it becomes a bad thing.
tl;dr: I'd do her, bite me.
