The set-up is simplicity itself: Go to Brazil, get a bunch of girls and a smaller number of guys, put 'em in a large room with a lot of lights and cameras, put a small stage in one corner with a group of masked, uniformed percussionists pounding out a non-stop rhythm track, and watch what happens. Plenty is what happens, from conga lines to boob-flashing tease to hardcore with the swoop of a panning camera. Tiny bikini tops fly off, leaving a trace of tiny tan lines, dicks pop out of briefs. A girl fast-jerks a dick into her mouth, in sync with the drummers pounding, as she gets fucked from behind by a guy also in sync with the drummers. When the guy comes, on her face, reluctantly - he's having a good time and doesn't want it to be over - the guy behind sits down on a nearby chair and the camera pans around her, catching more peripheral sex action in the background. Girls get fucked in standing doggie, hands propped against the bandstand. A pan across a girl's body as she gets fucked on a table catches a guy walking up to stick his dick in her mouth. This keeps going for the whole two hours plus, with a short intermission where the first party ends and the second begins.

Shot in both São Paulo and Rio de Janeiro and seamlessly edited together (the all-percussion soundtrack makes that easier) Rio Carnival Orgy 3 is a feast for the eyes and the ears. Fetish menus bring particular interests front and center, and the "bonus scene" gives another half-hour or so to the DVD viewer. Technical flaws are a sign of the reality of the situation and don't detract from the heat.
