Sculptured Katia Dé Lys, a supervisor at a construction site, wears red lingerie and black stockings for a live sex show performance. She encounters a handsome foreman, Kdube, on his Caterpillar, and begins to suck his flesh. Kdube takes turns licking and fingering her, and eventually removes her underwear. As the activity intensifies, Katia straddles Kdube's dick, licking his flesh and sucking him more. The hardhats come off, and they lean on the caterpillar, watching Kdube stretch her asshole before kneeling down and giving him what for his tongue.
