28 minutes in the movie, JJ Feild is stripped naked. We see his big cut dick and his massive balls bouncing around. We get a long view at his frontal while they hold him and even apply honey to his pubes! Then he he attached to a pole, and while a man comes deliver him, we get another long view at his frontal, and can admire his low hanging big balls. We even get close-up view at his genitals. In the second part of the movie, JJ Feild is playing naked with a girl. As she squeezes fruits over his body, we see his big dick again. This time he is showing us a nice chubby. JJ Feild is naked a lot in this movie. There are also a couple of other guys showing frontals, but not nearly as much as JJ.
Mid-movie, Ralph Fiennes gets naked in a barn. At first, it is kind of dark but we can guess Ralph's genitals as he is making love to a girl. Rapidly the animals in the barn get upset. At that point, and for 5 minutes we get very clear frontal and rear views of Ralph Fiennes. His foreskin seems rather short and his balls are really big.
