Careca, the city's most infamous cock-hungry local, is back for another round of oral debauchery in Curitiba. Part IV picks up where the last left off, with Careca's eager mouth already wrapped around a thick, leaking cock. He savors every inch, his lips stretching wide to accommodate the generous girth, his tongue flicking and teasing, coaxing moans of pleasure from his partner. The city's anonymous cocks are no match for Careca's skilled mouth, as he continues his insatiable quest for oral gratification.
