In a dimly lit, sweat-soaked room, a group of Brazilian "putas" - whores in the best, most empowering sense of the word - come together for an evening of uninhibited pleasure. They writhe and grind against each other, their bodies slick with lust, their hands and mouths insatiable. The air is thick with the smell of sex, the sounds of wet, slapping flesh, and the cries of ecstasy as they push each other to the brink of orgasm, again and again.
