No.

Jane hung limp in the barn, soon she was sandwiched between two cows. She was barely aware of what was occurring, the hormone injection had dulled her mind. Her mouth hung open and she drooled onto the ground. She wasn't aware of the plastic tubing and cups descend from the ceiling until the cups attached to the nipples of her swaying breasts and she felt the vacuum suction secure them there. Jane moaned as they tugged at her breasts, but even in her half conscious state, she realized what was about to happen and tried to remove the suction cups with her hands. Just then, a feeding tube was wedged into her mouth and down her throat. Jane felt a cool liquid poor down her throat, full of all the nutrients a cow would need to survive, her arms tugged at the tube and at the suction cups, but she was now too weak from the hormones and dropped them again to her sides.

It was then that she heard a bell ring and felt a hard tug on her left nipple. Jane groaned, it was both pleasurable and painful. A few seconds later she felt a similar tug at her right nipple. As the cows up and down the line mooed, Jane grunted and moaned. The left nipple was tugged again, and then the right, and then the left. Her chest tingled, and slowly it became less and less painful, and more and more pleasurable. When the machine registered that no milk was being drawn, another syringe descended from the ceiling and injected Jane with more hormones. Overwhelmed, Jane passed out in the tethered position she was in, bent over with the suction cups attached to her nipples. As the machine pulled on Jane's breasts, first a trickle, and then a stream of milk began to move through the plastic tubing.
