25 Days of Gays: Will-o'-the-Wisp (2022)

The Portuguese film Will-o'-the-Wisp (Fogo-Fátuo) follows Alfredo (played by Mauro Costa), the young prince of Portugal's deposed royal family. Alfredo's sense of environmentalism, instilled in him since his childhood, leads him to join a fire brigade to help fight forest fires caused by climate change. He is assigned to Afonso (played by André Cabral) to help with his training, leading the two to fall in love, while Alfredo learns more and more about his new job and the firefighters whom he'll be working alongside. Both Mauro & André showed rear nudity during the film, with André also showing frontal nudity. The film also featured frontal and rear nudity from João Villas-Boas in his role as one of the firefighters. João Caçador & João Reis Moreira both showed off their butts in jock straps playing firefighters as well. The trio show off poses from their firefighter calendar shoot, which were meant to simulate famous paintings. Afonso also shows Alfredo a series of penis photos in one scene.
