Boobs and Butts of Prey
From Birds of Prey 3. I’m actually a big fan of Birds of Prey, but these images are classic Escher Girls.
Both of these have actually been on this blog before (here and here for those curious), though these are better quality so I'll accept the re-submission. Also, the cover in the original post was kind of buried under a tree that somebody submitted which looked exactly like her fighting pose (It really does, check it out).
