In the crowded, bustling metro, a curious hand reaches out, snaking its way through the sea of bodies to land on a unexpected bulge. The owner of the hand, a young man with a mischievous glint in his eye, feels the growing hardness beneath his palm. The recipient, a muscular, tattooed stranger, doesn't flinch, but his breath hitches as the grip tightens. The crowd shifts, pushing them closer, and the young man leans in, whispering, "You're hard," before dropping to his knees, his hand never leaving the growing bulge.
