More tits, more milk

Kate winced as the pair of needles punctured her skin. Two syringes were being emptied into the area underneath each of her hulking tits. Steadily, they were relieved of the blue liquid inside them, and were withdrawn from the captive model.

"Moooo!" Kate moaned, forgetting she could no longer speak.

The injection site itched like crazy. Kate desperately wished her hands were free, if only to rub the spot underneath her boobs.

The physicians must have noticed her discomfort, placing their hands beneath her pectorals. For a moment, Kate felt satisfied by the pressure and rubbing on her chest. And her.... nipple? Yes, it felt like they were rubbing her nipples.

"That's impossible." she thought, looking down to see her bare breasts untouched. "How can? Wait. Unless....."

Though she could not see them, beneath her first pair of breasts, little mounds with pretty, pink nipples were forming.

"They're not! They.... they can't be!"

Kate mooed loudly again while the doctors prepared two more syringes. This time, they were filled with the emerald-green solution Kate had been all too familiar with. Without delay, they injected the growth formula into her newly-grown row of milkers.

A wave of numbness, followed by profuse warmth struck her budding bosom. She could feel it, the bloated, stretching feeling hitting her tits. She still could not see them, but their growing weight was impossible to ignore. Skin rubbed against skin as they came to equal her original pair in size.

****, Kate struggled in her harness. Her quartet of knockers flopped about under her, and might've felt pleasurable, were she not in a state of panic.

"Awe jeez. She's getting really scared. I think we gotta put her out again." she heard one lab worker say.

"MOO! MOO MOO!" Kate cried, begging them not to.

A cold hand pressed down on her arm as one last needle entered her. Kate fought to stay awake, but like in the hallway before, she eventually succumbed to the sedatives entering her system.
