Meanwhile, the farmer is also still working on nipple enlargement for Katie. One of the best HuCows ever, Katie has HUGE udders, but only tiny nipples. To be a good HuCow, a girl needs longer nipples so the milking machines can grip them better and they get sucked into the milking tubes much further. Katie has been undergoing relentless nipple training for years now, and the results are definitely visible. Her large udders are starting to develop longer nipples, which can be stretched much further. It’s not an easy life for Katie, but she is used to it. Don’t worry!
