The scene opens with Roberto, a sweaty, frustrated man who has just been denied sex by his wife Maria. He storms off to take a shower, muttering obscenities about his arch-rival Guilherme Gaucho under his breath. As Roberto lathers up, he hears splashing and moaning from the bathroom.
Intrigued, Roberto peeks around the door to see Guilherme pumping vigorously into Maria against the wall of the shower stall. Roberto's face twists in rage as he watches them, but also takes in their lustful display. The hard, smooth muscle of Guilherme's back ripples as he slams into Maria, his moans of pleasure echoing in the steamy room.
As Roberto watches, he becomes increasingly aroused despite himself. He grips his growing erection through his pants, unable to suppress his desire any longer.
