Carlos, a globe-trotting libertine, discovers Santiago's underbelly, a wild side that mirrors his own carnal appetites. A captivating local vixen, a stranger on the streets, entices him with a provocative proposition. "¿Te gusta ser mi perrito?" ("Do you like being my doggy?") she purrs, leading him on a lewd journey through the city's neon-lit back alleys. They fuck with reckless abandon, her aggressive domination fueling his insatiable lust, as they mark their territory in a symphony of grunts and moans.
