The younger brother, caught in the throes of puberty, is alone in his room, his mind filled with thoughts of his older brother's body. He's never acted on it, but the tension between them is palpable, a silent understanding that they both feel the same way. He tentatively wraps his hand around his cock, stroking softly, his breath hitching as he imagines it's his brother's hand. The older brother, hearing the soft moans, enters the room, catching his brother in the act. Instead of anger, there's a spark of understanding, a shared secret that binds them even closer.
