In the dim light of their shared bedroom, the brothers' eyes meet, and a spark ignites. They're both curious, both horny, and both craving the touch of another man. They begin to explore, their hands trembling as they stroke each other's uncut cocks. The room echoes with their soft moans, the air thick with the smell of precum. They take their time, learning each other's bodies, their first time a tender, intimate dance of discovery.
