I love a version of this that my partner and I call "panther style". It's not quite stacked snakes, but it's like doggy except I'm lying down with my legs apart and my rump slightly raised, and he is between my legs fucking me from behind, but most of his body is lying on top of mine. Our legs are bent though, not stretching out lengthwise. It's an AMAZING position for pleasure, and is also intimate and dominant. We can still kiss, and he can hold my arms down for leverage. It's fantastic.
