There are three earthen houses in a farmyard in mouse nest, and the light is on in the east room. Only 20 watts of incandescent light makes the room look dark. Under this dim incandescent lamp, there were three people, two men and one woman, all middle-aged people. One of them, who looked less than 40 years old, was dressed differently from a countryman. He stood on the ground near the edge of the Kang with a high-end digital camera in his hand. The lens was facing two other rural men and women who were much older than him sitting in the middle of the Kang. The women on the Kang began to undress first. Her upper body is just a cheap floral shirt, buttons one by one, because there is no bra on, and before the shirt is completely removed, two white drooping soft breasts have been exposed to the two men. She took off her shirt and casually left it beside her. Looking at the camera lens, she held her milk with her hands, rubbed it slowly for a while, then held the nipple with her thumb and index finger, and rotated and twisted it.
