Tia felt the bus slow, then turn the corner. She came out of her recollection and smiled at Colleen.
Tia said, "Hey, let's have some fun Thursday night, we'll both be off for our 3 days, and we can get loose!"
Colleen grinned, and she turned to Tia, running her hand softly over Tia's stomach.
Colleen cooed in her ear, "Sounds great, so long as I get loose with you baby! You've spoiled me for any other lover, you know."
Tia smiled, and whispered back, "The feeling is very mutual I assure you baby" as she brought her hand up, and smoothed Colleen's long red hair back.
The bus pulled up to the plant doors, and one of the girls who was in a chipper mood, called out, "Ok, let's head for the salt mines!"
There were 20 ladies aboard the bus, and everyone got out and went through the big double doors that opened for them. Tia and Colleen headed for their assigned room, it was a well-established routine. They had to be prepped, it was a half-hour procedure, and as they started the prep routine, Tia recalled the first time that they had discovered what work at the Calto plant entailed.

They had gotten off the bus, and stood around, unsure of where to go. The big double doors opened, Gal-tor and Con-set appeared and motioned them to come through the door.
They did a headcount, and nodded, satisfied, all 20 of them were present.
"Please, follow us, we will assign you to your prep rooms. You have to be prepped before you will be taken to the working area."
Tia and Colleen exchanged a look, wondering exactly what being prepped meant. They were pleased to see that Gal-tor and Con-set appeared to understand the strong bond that had developed between her and Colleen, and they were shown into a room with three chairs, a desk, and a cabinet.
Con-set went to tend to the other women while Gal-tor stayed with Tia and Colleen.
"Please strip, and we can begin the prep," Gal-tor stated.
Okay, Tia thought, more nudity, strange how they want us nude so much. She quickly doffed her clothes, and Colleen did the same. Gal-tor took a small device from the cabinet.
"This is a nasal inoculation device, that will spray the prep fluid into your nostrils, it is less painful than the traditional injection needle."
Colleen said, "Just a second, what exactly are we being prepped for?"
Gal-tor looked surprised, he said, "You said it yesterday, about being a milkmaid, that's what your position is."
Tia added, "And we have to be naked for this?"
Gal-tor replied, "Yes."
Despite the rumblings of disquiet they felt, Colleen and Tia complied, and he squirted the device into their noses. It was fast-acting, and Tia and Colleen could feel their breasts become heavy as if weighted down with something. They both looked down and gasped as they saw their breasts growing, adding cup sizes and inches quickly. Tia ballooned from a 36D to a 42DDD, and Colleen pumped up from a 36C to a 42DD. Their bigger breasts stood up, not a hint of sag, and the feeling of their breasts filling became more pronounced.
Tia stared at the sheer size, fuck, it felt like mountains were attached to her chest, as she said, "What was in that prep fluid?"
Gal-tor replied, "A genetically enhanced form of prolactin. It is the hormone that regulates milk production in the human female. There are also some bio-engineered compounds to enhance your breast size, increase your libido, and to further stimulate your milk production. This helps to ensure optimum collection."
