The farmer loves tiny Lina Roselina, even though she has very small udders. She is obedient, fully trained, and she really really wants to be a HuCow. The farmer gives her every opportunity to prove herself, and Lina doesn't hesitate to put the vacuum therapy machine cups on her small udders. The machine is very powerful, it will keep her udders enlarged at 4 times the original size with a strong vacuum. Of course, when the vacuum is turned off, they reduce in size again, but this is not about one session, the udder tissue will get stretched and it will increase in volume if Lina gets enough sessions like this, in combination with the right feed. Lina is determined to be a good HuCow, and she is adorable!
