I've had trouble sleeping last night because of a (now gone) fever. While I was doodling my morning warm-up sketch, I started browsing my FA submission page and my Tumblr feed, and I was like "pony, Five Nights at Freddy's, pony porn, FNAF, pony, FNAF porn (wait what), pony..."
Apparently my sleepy brain got those mixed up at some point, and this is the result. The title pretty much wrote itself.
