The Vacuum Therapy Machine 1080p

One of our resident HuCows is Valentina! She is so cute! We like to test new machines and configurations on her. Valentina is still a bit scared and very sensitive, so she makes a lot of noise when something hurts. This means we can read her very well, even when she is gagged. Today, we are testing the Vacuum Therapy Machine with some bigger cups. In case you didn't already know: pumping the udders makes the skin more supple, allowing the udders to stretch and grow. But you have to do it gradually and very often. That's why we are so busy here at HuCows.com! Of course, there was also time for a member favorite: nipple clamps before AND after pumping. HuCows don't like nipple clamps after pumping, but members do! Valentina hates you now. But that's ok.
