Ballet dancers put their feet thru it.
Thought it was common knowledge.
Ballet dancers feet are atrocious but they typically can't get preggers and don't get periods. I dated one when I was younger, she actually took my virginity. I shot the club up, never got her period and was a shook one for a hot minute. Then she told me her training was so intense she doesn't get periods and can't get preggers and said she liked having the club shot up. Needless to say that made me careless cause the next chick got preggers.
