Swinging USA - S0.E2

Window cleaners Chris and Lorraine Burns are swingers - as a couple they like to have sex with complete strangers. Together for nine years, they've been swinging for three. But for four days in early summer, they're swapping more than sexual partners. They're off to steamy, sunny Florida to sample some swinging - US style. Their mission - to see if there really is any truth behind the so-called 'special relationship'.
