I’m currently working on a pony girl uniform. :)
Since you can’t be a pony girl without a tail, Sir helped me find a fancy pony plug that stays turned up. Its pretty big for me so I had to spend some time ramping up, but once I was able to get it in, it stayed up as advertised and looks way better than the traditional pony plugs. The tail is kept in place by a little metal piece that rests between the cheeks to stop it from twisting downward.
Sir likes that its impossible for me to ignore, and of course he always likes watching sluts wagging tails and crawling around on the floor begging for cock. :) My only complaint (besides the size) is that it’s incredibly heavy. Much more heavy than my other metal plugs. Yikes.
My pony uniform isn’t quite complete yet. I have a body harness, head harness and some pony boots ordered, but I had to test the tail to make sure it works ;)
