Discreetly tucked away in the bustling Jabaquara district, the Carrefour Banheiro is a haven for rugged, anonymous encounters. Muscular, tattooed men, their bodies glistening with sweat and soap, soap up in the communal showers, their eyes locked on the prize. The air is thick with tension and the scent of cheap, musky cologne. A single, rough grunt signals the start of a raw, unbridled battle of wills, with no mercy shown. The losers submit, their bodies marked with the victor's fluids, their pride swallowed.
