Flat is justice

It's true though. Flat IS justice, anyone who says otherwise clearly doesn't get the appeal. It's elegant, it's understated, what else can I say? No, I'm not trolling. I frankly don't care if not a single man in the world shares my preferences, flat is justice and that's a fact!

Imagine liking bouncy, buxom, full-figured breasts, like ew. Flat ass and tits are MUCH more elegant looking (not too flat though). Flat is justice.
