So for a while, I've been meaning to compile a list of links to ballbusting stories/blurbs that people probably missed. Most of these were posted in the comments, or in a forum thread, or things like that, so unless you follow EVERYTHING online, there's a good chance you haven't seen a few of these before. (Feel free to contribute your own links as well – I'm sure there are things that I've missed, too!)

For starters, here are about a dozen snippet requests by Aekrilos here on FurAffinity, all of them really excellent:

There are a handful of other snippets in the comments of my past journals here on FurAffinity, as well. Here are two by HandofBlades:

Anyone who's missed UnderPressure's Bad Ideas index is really missing out: he's got 50+ scenarios, almost all involving ballbusting.

An MLP ballbusting fic by Felagund that I think a lot of people missed:

The FemaleDom.com furry ballbusting thread is also a treasure trove – it started almost six years ago, before I even started writing. For a while it was probably the best place on the web to find furry BB. Here are a few posts in particular I remember:

And finally, a few verrrrry old leftovers from LiveJournal. This might be the earliest furry BB fiction I've ever found:

Okay – sorry for the gigantic wall of text. I think that should be more than enough to start. I just didn't want to forget anything awesome :P Go check all this stuff out! And show the authors/creators some love! :)
