This film features beautiful women working at a construction site. AV actress Yui Tomita successfully picks up women at the site, building intimate relationships with the female workers. The female plasterer initially resists the oil massage but is surprised by how good it feels, gradually becoming more open. Despite her initially blunt attitude, she ends up climaxing multiple times from Yui's techniques, even taking the cock deep into her throat during fellatio. The on-site atmosphere and the women's transformation are the highlights.
