This topic is quite frankly too weird and icky for us to attempt to explain so we'll leave it to Tatiata to tell you in her own words.

"You insert one of the balls in your vagina, and it has a string attached to it with a little hook at the very end. You fix a second ball onto this hook."

Thanks Tatiata. As for how she got into the sport, here she is again.

"After I had a child, my intimate muscles got unbelievably weak. I read books on Dao and learned that ancient women used to deal with this problem using wooden balls.

"I looked around, saw a Murano glass ball and inserted it in my vagina. It took me ages to get it out!

"It's enough to exercise your vagina five minutes a day, ladies, and in just one week you'll be able to give yourself and your man unforgettable pleasure in bed."

An excellent explanation - we're off to have a wash.
