25 Days of Gays: Light Gradient (2009)

Light Gradient is a gay film from Germany. It tells the story of Johann (played by Sebastian Schlecht) and Robin (played by Eric Golub), a young couple biking through the woods on a camping trip. After several mishaps, they come upon a farm where they befriend a woman and her teenage son Henri (played by Denis Alevi). As their relationship with the family deepens, conflict arises leading them back into the woods where things take a mysterious turn. Both Sebastian & Eric are featured in multiple frontal and rear nude scenes from frolicking in a lake to getting hosed down to clean-up. Denis is shirtless for a swimming sequence with his co-stars who end up naked once again.
