The insanely hot and full figured Kelly Brook in the movie Survival Island, playing a wife of an abusive rich husband, who is shipwrecked on a deserted island with him and a handsome crewmember. She ends up succumbing to the younger fitter stud on the beach, and later, when her husband has returned from fishing, she fucks him again, knowing her husband is watching them! What makes this even hotter, is behind the scenes, she was really married to her on-screen husband Billy Zane at the time, so she was really performing very convincing soft porn scenes in front of her real life husband!
