Two Schoolgirls Use the Human Toilet Extensively

Two schoolgirls discover a loo. It's not an ordinary one. Instead of a sewage pipe, a human being is attached to it. The head is clamped in such a way that escape is impossible. The two giggle and then test it out. Huge amounts of pee flow through the toilet bowl. It doesn't stop splashing for a few minutes. The toilet gurgles away, which amuses rather than worries the two of them. They certainly don't piss any slower.
