Someone asked in FSA to hear a lady pee. I felt like using my muscles. Weirdly enough I've been working on those particular muscles since I was young (younger than the age of 10). I had an overactive imagination and had this thought about what if I was somewhere and had to not be making noise. So I started to practise how to abruptly stop my urine flow. Or the other scenario was if I was ever captured and tortured and had to pee or stop peeing on command. I was a weird kid.
