Long shot, but here goes. I've spent HOURS on SoFurry trying to find this damned story and I can't locate it. I don't remember if that was where I read it. It was fairly recently that I read it, like within the last few months, so I'm sure it's still around and I just forgot where it was.
WARNING: involves feral
The story is pretty short—some type of male anthro is tending a barn full of feral goats or something, and there is a male feral goat that like catches his eye and encourages him to follow him over to a private area, and the male anthro's vibe is 'I really shouldn't be doing this at work,' but he succumbs, and is attracted to the musk of the feral goat's tailhole, and there's sniffing and (possibly) rimming/anal to follow, while the goat seems bored/satisfied at luring in another person for his pleasure. Something like that.
Anyway, if this sounds familiar to anyone, I'd love to know. Been trying to find it for days and feel like I'm going crazy
