In the dimly lit backroom of a bustling Brazilian bar, two rugged, tattooed men, both Corinthians fans, exchange knowing glances. Their conversation, laced with sexual tension, turns to the art of trigonometry, a euphemism for the dirty deeds they're both eager to perform. The taller, more muscular of the two, a self-proclaimed 'ladrao' or thief, leads the way to a secluded alley. There, under the flickering glow of a distant streetlight, they indulge in a steamy, passionate session of 'suruba', the Brazilian term for group sex, redefining the meaning of a 'gostoso' or delicious encounter.
