Hucows are genetically engineered humans. They are sterile so they are focused on their job. They all have cow ears and cow horns. Their breasts are large and their nipples are very sensitive and easily lactate to produce large amounts. If they have a penis, they produce large amounts of sterile cum that is also used for dairy products. Hucows are more carefree, direct and always horny. Sex is common on hucow farms and increases lactation and leakage. The industry has developed a variety of additional modifications: Breast implants put lots of pressure on the mammary glands, causing constant leakage and higher production. Nipple piercings amply the stimulation for milking on the nipples. Storage implants are sophisticated breast implants that can directly store produced milk so it can be manually expelled when the time comes. This prevents any loss from leakage. Equine penises are larger and produce more cum. They also stimulate hucows much more, increasing their milk production and speeding up their release when fucked during milking.
