Germinal by Émile Zola

Towards the middle of August, Étienne settled with the Maheus, Zacharie having married and obtained from the Company a vacant house in the settlement for Philoméne and the two children. During the first days, the young man experienced some constraint in the presence of Catherine. There was a constant intimacy, as he everywhere replaced the elder brother, sharing Jeanlin's bed over against the big sister's. Going to bed and getting up he had to dress and undress near her, and see her take off and put on her garments. When the last skirt fell from her, she appeared of pallid whiteness, that transparent snow of anaemic blondes; and he experienced a constant emotion in finding her, with hands and face already spoilt, as white as if dipped in milk from her heels to her neck, where the line of tan stood out sharply like a necklace of amber.

He pretended to turn away; but little by little he knew her: the feet at first which his lowered eyes met; then a glimpse of a knee when she slid beneath the coverlet; then her bosom with little rigid breasts as she leant over the bowl in the morning. She would hasten without looking at him, and in ten seconds was undressed and stretched beside Alzire, with so supple and snake-like a movement that he had scarcely taken off his shoes when she disappeared, turning her back and only showing her heavy knot of hair.
