Sophie's relief grew as her udder was steadily emptied, the mechanical tugging of the sunction tubes a strange but undeniably pleasureable sensation. Looking down at the tubes however Sophie noticed something strange, her milk seemed to glow faintly, so dimly she wasn't sure if it was real or some trick of her changed eyes.
A clank distracted Sophie from her inspection of the milk, looking up she saw Isabel unwinding the hose used to drain the milking machine, quitely humming to herself as she did. Even as full as she was the machine was made to hold several cows worth of milk, so why was Isabel going to empty it now? Much less while she was still being milked.
Sophie didn't have to wait long to get her answer, to her dismay Isabel didn't unwind the hose far, unspooled enough she brought the hose to her lips and bending down reached for the release tap. "Moooahhh!" Sophie protested, was Isabel really planning to drink straight from the machine?
Pausing Isabel looked to Sophie "Woah relax girl, I'm just having a taste, I haven't had breakfast yet" Isabel explained. "Mooo..." Sophie responded, akwardly pawing at the ground with her hooves as she tried to convey her displeasure at the idea to little avail.
