This "piba" or girl, a "mina" or woman in the making, is a master of her craft. She "perreando," perreo-ing, a dance that's all about the ass, and she does it with a skill that belies her years. Her "punteo," the rapid, rhythmic thrusts of her hips, are like a musical punctuation, a beat within the beat. She's a "chava," a young woman, but her body is all woman, full and ripe. The room is filled with the scent of her, the sound of her, the sight of her, a sensory overload that's pure, unadulterated sex.
