This is a sexual maneuver that
prostitutes use to sexually please men.
The woman will first strip naked and backbend into a bridge. She will stay in that position for as long as the man wants. The man will then remove his trousers and mount the woman in the backbend. He will slide his dick into the "crack in the bridge" and they will begin
sexual intercourse. When the woman climaxes, a spray of water from underneath the bridge will spew forward as a result of the backbend.
Mmmmm... Yummy, right?
