When a toilet breaks down at a construction site, a worker comes to a house in a quiet residential area to borrow the toilet. Chinami, a housewife, lives there. With too much free time on her hands, she seduces some physically powerful construction workers. Embracing their well-trained bodies, Chinami's thirsty sexual desire is awakened. She traces their muscles with her tongue, sucking and licking their sweaty penises. In the house where her husband is not around, she eats out all the men from the construction site, and finally climaxes covered in semen in an insatiable foursome.
