Under the neon lights of a Rio nightclub, a horny milf spots a young, innocent-looking "novinha." She's a "piranha," a girl who loves cock, and the milf, a "coroa" with a reputation for turning young girls into insatiable sluts, can't resist. She drags the girl back to her apartment, a grimy, sweat-soaked den of debauchery. The milf, a "puta" from the streets of Rio, teaches the girl how to satisfy a real man, making her suck, fuck, and even take a creamy load all over her pretty face. The girl, now a "greluda" or slut, begs for more, her body aching for more cock.
