Eh I don't really care if the pose is borrowed from somewhere? There is only so many ways you can bend the human body, so I don't see how that's plagiarism. Plagiarism would be outright using the source art, or at most tracing it. Looking at it and drawing the same pose? That's not plagiarism.
You want a guy eating a girls ass while she looks back at him over her shoulder? There's only so many ways that's anatomically possible, so it's certain there will be art that has the same pose, and if you can't quite imagine it in your minds eye so you use a model, or action figures, or another artists rendition of it, it's still YOUR art.
