A HORNY couple is staging live, outdoor sex shows in the Hamptons – and they don’t care who sees them. “The first do-it-and-dash site was in an East Hampton park several weeks ago,” a source tells entertainment journo Bill McCuddy. “Then, the 20-something pair struck again in broad daylight a few days ago in Southampton’s pond side park on a cement fence.” There are witnesses. “A spunky 14-year-old rode up on his Schwinn and asked the pair for a cigarette,” the spy said. “The naked duo fished through their nearby clothes and offered him a Camel, then said, ‘Now beat it!’ ” Cops are trying to nab the randy lovers.
