We need more red cow milker! Nora Sparkle had already been milked by our most powerful machine, but we thought we would just do it again! Not fair for soft-uddered Nora she gets to go twice in a row on this machine? Probably not. It is so powerful because cows have 4 udders so we blocked 2 of the cups, putting all the vacuum pressure on the remaining two cups. Not easy, but Nora is a trooper. In fact, she has quickly become the farmer’s favorite. He keeps her at home too, for some more personal submissive training.
