fiddlemod replied to your postSo I drew incest. And of course, it’s too taboo…
I don’t think incest is really very taboo on most image sites. Plus you can throw just about literally anything on derpibooru.

But what if Derpibooru didn’t have a pic like this on record?

It slightly puts me off since something like this hasn’t been posted anywhere. (Maybe it was in some old imageboard thread.) And there’s kind of a reason why.
