I posted a while ago that my favorite type of angle is where the asshole isn't fully shown but there's just a slight fleshy opening to it while the cheeks themselves are closed, and lamented that there was such little of it and no tag. But now with this influx of kyojiri loli from western artists, they pretty much all do it (like in OP), and I'm in love.

Such huffable, face-buryingly-finger-lickin-good asses I've been hoping for for so long. I hope they never stop making these.
