i think the first one would do.it's called leg lifted doggy or do you mean sideways fucking where the girl does a vertical split with one leg on the ground and the other over the mans shoulder?
Also, I gotta disagree with you on the Amazon position, thats more of a humiliation/femdom thing than a girl riding you, it can kinda work in a snu snu kind of way when the girl is at least a foot taller than the guy but Storm is too feminine for it. Storm would need to be more like pic related.
humiliation no, femdom sure, but i don't see how that is much of a problem, and for all accounts we don't see MC size/height, so he can be smaller or taller based on the player perspective.
