What is booty talk? It's an ancient form of communication fallen into disuse among Caucasian hos, but still practiced by some of the African-American porn tribes where the white man has never laid pipe. Traditionally, the female expresses her fertility by shaking her backside furiously at an attractive male, who eagerly responds by depositing his nut inside her quaking booty. Porno anthropologist Spunky searches the wilds of modern L.A. to bag specimens and haul them back to his crib to study the custom. Fortunately, he has a large pool of all-natural homegirls to draw from. The most eloquent booty lingo in captivity belongs to Miss Brown Sugar. When her jiggy black bottom is well-oiled, it sings.

Spunky's documentation doesn't miss a beat. He makes some rare finds in Kiki, a ripe, mannishly-hipped number with a cunt like a prickly pear; Erica, a blushing African-Asian; and Meow and Rain, who survive their initiation ritual in the comfort of a limousine. Wesley Pipes displays a strikingly photogenic cock. But even when this threatens to upstage the booty. Spunky, unlike so many African-American directors, keeps his camera focused on his women's reactions. He knows how to keep a sex scene tight and groovin'.
