Source is SFW, rest of the tumblr is NSFW.
Tumblr – Source

Amazingly, I didn't actually edit this one. I know. I'm surprised too.

To whomever downvoted this: It's a butt. If you find something sexual about a pony butt, then you have problems – not everyone else. Some people get off to feet. Should we NSFW tag feet images too?
