In the heart of a bustling city, a lone figure stands with his back to the wall, blending into the crowd. Unnoticed, he starts to rub his bulge, eyes darting around, adrenaline pumping. His hand moves faster, his body tensing as he fights to maintain composure. The world around him fades as he reaches the edge, groaning softly as he comes undone, spilling his seed into the city's rhythm.
