The milking chamber.

When the guards finally released their grip on Billie, she was in what appeared to be a large warehouse filled with barnyard-decorated stalls. Pushing her forward, they motioned her to enter one of such stalls, marked with a big "6" sign overhead.

In the stall, there was a hardwood floor with equipment Billie didn't recognize at the room's center, as well as what seemed to be a small reservoir hooked up to it by a collection of hoses.

Once more, Billie was grabbed by the shoulders and situated by the device.

"Kneel, and bend over."

"Moo?" Billie asked. She was rather confused about what was happening.

The second guard suddenly tore off Billie's hospital gown, revealing her naked figure.

"Kneel, and bend over!" she heard again.

Not wanting to chance anything, Billie did as she was told.

As she got down on her hands and knees, she could feel the weight of her new assets. Looking down upon them, Billie couldn't help but despair at what had become of her body. Though it was the least of her current problems, she was already quite scared of what people would think of her. The last time she showed off some cleavage, she lost a substantial internet following, and that was before she was sporting S cups!

Billie was pulled from her thoughts back into reality as she felt something secure itself onto her chest. On each breast was a metal cylinder hooked up to the mechanism beneath her.

"She's hooked up, bring in the eggheads." one of the goons ordered through his mask.

With that said, another figure entered her stall, only this one was dressed differently. Unlike the first two, who were dressed in black body armor and balaclavas, this person was wearing something akin to a cleanroom suit with rebreather and goggles. Most importantly, the "egghead" held no weapons or equipment, save for two syringes filled with orange liquid.

The cleanroom worker knelt down, massaging and then injecting each of Billie's breasts with the unknown liquid.

"MOOOO!" Billie groaned, waiting for the stinging of the needle to subside.

"Easy now." said the scientist. She seemed to calm down at his words, allowing him to finish and remove the syringes. He then pressed an unmarked, green button on the machine, bring it to life with a steady hum before looking back at the well-endowed girl.

"Since this is your first time, you'll probably feel some discomfort, as well as some swelling. But don't worry. It gets easier, sometimes even fun."

"Moo?" Billie said, tilting her head.

But right then, she could feel it. Her breasts felt not just hot, but also heavy. In fact, she felt even heavier than she did before.

While afflicted with whatever was happening to her, her escorts quickly began securing her in place with leather straps bound to the floor.

"Moo!" Billie cried. The weight in her chest just kept growing and growing. Though they were hidden under the devices strapped to her, Billie could feel her tender nipples stiffening.

The star rocked about in her restraints. Not enough for concern, but enough to jiggle her hefty tits about. If Billie didn't know any better, she would've thought they were filling with something. Each second, the feeling of fullness increased, becoming more and more potent. It was as if every ripple, every shake of her massive mammaries were making something slosh about inside them.

Finally, when she could bear it no more, the full, sloshing feeling rushed straight to her nipples.

Billie mooed extra loudly. Even if she were able to speak properly, she would've lacked the ability to put a coherent sentence together. The flood gates had been opened, and Billie's warm, creamy milk flowed from her swollen teats into the large hoses underneath.
