Sexy Japanese Big Boobs Japanese Ai Sayama is a perfect example of natural busty japanese in this small video I put together showing the busty effect of Sayama. I know some people say that busty japanese boobs look more like a japanese garden crab, which may not be true, but the truth is that the texture and shape are more or less similar to those of a japanese garden crab, so it's definitely not the best choice for a natural busty japanese giantess costume (sorry guys I'm a bit of a picky guy hahahaha). But if you're looking for the best realistic model for your Asian Big Boobs costume, I recommend Sayama as it looks about 10 times better than her video..
