The room echoes with the sounds of their heavy breathing and the wet, rhythmic slapping of flesh against flesh. The younger brother moans, a guttural sound of pleasure and surrender, as his older sibling expertly works his cock, bringing him to the brink of ecstasy. They switch roles, the younger brother now in control, his hand wrapped around his sibling's thick, veined cock. He jerks him off, his fist a blur, until the older brother's body tenses, and he lets out a roar, his cock pulsing streams of hot cum onto the younger brother's eager, waiting tongue.
