Our Australian HuCow Cobie is continuing her udder expension sessions! Last time, she was on her knees as the electronic breast training machine pumped her udders bigger and rounder than they already were. Cobie was exhausted, but we need to continue her expansion. This time we have muzzled her and chained her to the milking frame. She is still locked in her chastity belt, nothing we can do about that as we are not her official owner. But the belt is not in the way of pumping her perfect round udders! Getting pumped is hard, and Cobie is soon very tired, but the machine just goes on and on… we even use infrared tissue stimulation mode!
