The weight of their secret presses down on them as they frantically strip, their hearts pounding with fear and excitement. The older brother, his cock throbbing with lust, guides his younger sibling's hand to grip it firmly. The younger brother hesitates, then tentatively strokes, his inexperience evident in his trembling touch. The older brother, his voice barely a whisper, urges him on, "It's okay, just like you would do to yourself." They find their rhythm, their bodies tensing as they approach the edge, their moans muffled by their hands pressed against each other's mouths. In a final, desperate push, they come together, their hot, sticky seed spilling onto their hands and bellies, a testament to their shared, forbidden desire.
