A naked couple have been caught on camera having sex on a beach - in full view of stunned holidaymakers. The pair were seen romping on the sand as a 4x4 vehicle full of tourists pulls up alongside them. Behind the camera, beach-goers can be heard giggling uncontrollably as the amorous lovers make no effort to disguise their antics. It is thought the footage was filmed on a mobile phone in Brazil, although the exact location is not clear. The video has now gone viral after being viewed thousands of times on video sharing site LiveLeak.
