Amidst the sprawling fields of Texas, a brother and sister, isolated and consumed by their desires, succumb to their taboo longing. He, a roughneck with calloused hands and a body honed by manual labor, takes her, a virgin but for her own touch, with a hunger that belies his stern exterior. Their bodies entwine, their moans drowned out by the distant hum of machinery, as they lose themselves in each other, the crude oil that surrounds them a symbol of their own untapped, dirty desires.
