While I, personally, would have enjoyed it more without the thong, I completely understand how making *every* clip about spreading naked butt hole would be creatively stifling. So, while I can't call it "perfect," I also don't fault it.
Luna's butt is pure happiness: the size, the shape, the skin. It's so inviting and comforting that, when she lay forward, my impulse was to snuggle in like a pillow and take a nap. The other thing that struck me was that her belly touched the bed. Luna's no SSBBW, so I it had to be something about the pose that made it happen. Even so, seeing it really pushed my button. All this, along with side orders of back rolls, dangling titties, and plenty of her amazing face made for a very enjoyable clip.
