Katarina is as free as a HuCow will be… still chained to the wall by her collar, but otherwise she is free to play with the farm toys. Her large udders have been sensitive her whole life, but now she finally understands she can pump them to get aroused. The HuCow transformation is complete, she is associating pumping with pleasure! Katarina starts with some nipple suckers followed by the electronic breast training machine. She pumps her pussy to triple the original size, and you can actually see her dripping with horniness. She gets her favorite dildo and pleasures herself, easily reaching an orgasm from the combined penetration and nonstop nipple pumping. She is such a good HuCow!!
