In the sultry Brazilian heat, Anderson Cavalcanti presents a voyeuristic glimpse into the secret lives of two siblings, bound by blood yet torn apart by lust. They attempt to distract themselves with mundane tasks, but their eyes keep drifting to each other, drawn like magnets. One, unable to resist any longer, begins to stroke their firm length, the other joining in, their rhythm synchronizing as they chase their release, bodies glistening with sweat, panting with need, until they finally find their climax, leaving them spent and guilty, yet craving more.
