"Hell no! There is no way I'm going to let you Humiliate me (even more) by having my new udder hooked up to a milking machine like just some kind of... of milk cow!" You shout at Bessie the Cowotaur as shes about to hook up the nozzles to the four teats on your gigantic udder. You suddenly realize that with your new giant udder weighing you down to the bed, there is nothing you can do to stop her anyway.
Bessie then looks at you humorously. "I hate to tell you this sweety, but to me you ARE just a Milk Cow now! I mean just look at your giant udder!" Bessie says as she drives the point home by gently slapping the side of your udder. Which causes the milk and fat to violently slosh around inside it that sends strange (and slightly erotic) sensations to your brain.
You quickly recover from the strange feelings of the sloshing milk in your still jiggling udder and say. "I don't care if I do have an udder now! I won't let you attach me to that milking machine!"
By now Bessie has become very irritated by your behavior. "Fine! You won't be attached to the milking machine then! But eventually all the milk in your udder will start to become uncomfortable, then painful. Eventually you will beg me to attach your udder to the milking machine!"
