This is the story of a man and a woman (Chan Chan and Juanica) who are building their house, and they need to go to the beach to get some sand. Chan Chan collects the sand and puts it on the jibe (a sieve for sand). Juanica then shakes it by stumping on it using her body, and to do so she shakes herself around and her breasts start shaking up and down in a rhythmic motion, looking at her as she dances in an erotical fashion Chan Chan gets aroused.
