An avid kite-surfer, Sir Richard agreed to add some thrills to his spills after a photographer suggested his girlfriend might enjoy a ride in the buff.
"What can you say if you are asked to pose with a naked lady?" Sir Richard told The Mail.
"I only wish I had eyes in the back of my head."
The model in question, Denni Parkinson
, also posed naked with Sir Richard in other shots taken by photographer Stephane Gautronneau
on and around his private Caribbean island, Necker.
Pictures were published in Italian edition of Vanity Fair magazine
