Udder Maximizing Training 1080p

Vina has grown so much as a HuCow. Even when she gets a little tired of all the milkings but she will never ever protest. She is completely docile and hasn't spoken in a long time. Still, we love to harness gag her, as she has also been trained to wear ballgags for any length of time. It just looks so cute! Today, we continue to maximize her udder size. Remember how she started out with tiny udders? They have quadrupled in size! Still, we like to grow them a bit more, so she gets lots of sessions on the electronic breast training machine. A very strong vacuum pumps her udders further and further, stretching them to fill the training bra. At the start, her udders fill out half of the cups, but we pump them to fill out the cups to the max! As with all HuCows, one udder is always a little bigger. Vina's right udder needs more work than her left one, but's she will get there!Please note: this kind of training hurts a lot because it just stretches more and more without letting any air out. Watch closely how well trained Vina is to take this kind of high power pumping!
