Their Finest (2016) is a British film based on the true story of Catrin Cole (Gemma Arterton), a secretary-turned-scriptwriter who gets appointed by the government to write propaganda films during World War II. She joins a cast and crew of a major motion picture production during the days of The London Blitz.
Natalia Ryumina is definitely the Finest one in the film when she rides a lucky guy to show off her bare breasts. We get to ogle at her right breast bouncing up and down as she goes for her pleasure ride.
