In the quiet of their shared room, the brothers stand before the full-length mirror, bodies tingling with anticipation. The older brother, a beacon of calm, guides his younger sibling through their first tentative explorations of each other's bodies. They press against each other, feeling the heat and hardness that mirrors their own arousal. The younger brother tentatively reaches out, tracing the outline of his brother's cock through his pants, a gasp escaping as he feels the thickness and length. Their reflections show the hunger and desire they've long denied, as they begin to give in to their taboo urges.
