It could be worse, you tell yourself. So far you just look like you're wearing kinky pants and a weird pair of costume feet. No big deal.
That's when you feel that strange sensation from before just above your butt. Looking back, you can barely make out the shimmer of the latex wavering with its surface. Within seconds, it begins to expand, again "growing" more latex from out of nowhere. What starts as a small mound soon becomes a hill, and then that hill slowly extends into a long, thin tail. You wonder why it doesn't match your feet, but at that very moment it balloons outwards in an instant, becoming much thicker and much wider and resembling the long, elegant tails cartoonists always seem to give anthropomorphised skunks. Finally, a pair of white lines race up the front of it, eventually meeting at the tip, and as they do it points upward and curls back about three quarters up its length, taking on the pose you'd expect a cartoon skunk's tail to.
Your new tail is shiny and surprisingly detailed, maybe even cute, but thanks thought of going through life with it terrifies you and the fact that the latex could keep spreading only scares you more.
