25 Days of Gays: In the Grayscale (2015)

In the Grayscale is a romantic drama from Chile that centers around Bruno (played by Francisco Celhay), an architect who is hired to build a landmark which requires him to work with a young gay teacher named Fer (played by Emilio Edwards). The two develop an intense connection that blossoms into romance. The film gets both actors out of their clothes for several scenes during the film. Francisco gets naked with multiple full frontal scenes from the shower to undressing. In addition to several rear nude moments, Emilio also provides a few glimpses of full frontal nudity during the film's climactic sex scene.
