After work was over, one of Joana's co-workers offered to take her home in his van. Secretly though, he wanted to "punish" Joana for the way she always behaved in the office, because she was always dressed with the finest business clothes and she was always attracting a lot of eyes. So this was one of the reasons the co-worker planned to get Joana's fine shoes a little dirty.
Their way home was through a muddy area: a zone where nobody was crossing and the guy knew that the cellphones have no coverage. He faked an engine failure, and of course the only one who could push the car was JOANA. :)
Check out the rest of the story yourself, and enjoy watching Joana under the shower.
