Young Vina wants to be a HuCow so bad, but her udders are very small. Today, she will get her first treatment with the electronic breast training machine. It seems a little harsh and painful, but it needs to be done! The machine can manipulate breast tissue in various ways, but the most obvious one is the vacuum training. This will make the udders more supple and it stretches the skin a little to enlarge the volume. I applied some oil to make the treatment easier for Vina, but it is still extremely sensitive for her. To have your breasts expanded to 3 times the volume by vacuum is not easy, and it takes time. I try out different settings and programs for her, because she wants this so bad!
