Down Rio way there's a tradition that still persists today that would shock many a gringo. It's called "Belly Riding" and has adherents who are wealthy and maybe a little eccentric. Belly riding is an art that only women can perform. It take a special harness that "slings" the willing female underneath a stallion. She controls the animal with her arms and feet, and an expert can gallop. It's a dangerous sport, because the stallion has his huge erect penis firmly planted in the woman's vagina the whole time. Their joining can last as long as five or six hours, so isn't something for the faint of heart. This story is about just such a Brazilian family, their lives and times.
