Cassidy struggled against the restraints, but the machine was designed to control beasts much stronger than her. Fortunately, the machine merely idled, waiting for a nonexistent employee to attach the tubes manually. That meant her modifications were still in place, which meant the machine should harmlessly stall out until a coworker found her!
She looked up, spying a camera. That’s right, security should’ve seen this. They’re actually the last ones out the door. They’ll see the machine has restrained an employee, and get her out. Worst case scenario, her coworkers would return the following morning. She’ll be a laughing stock, but at least it won’t get worse.
The machine beeped. “No personnel detected. Reverting manual steps to automated.”
Well, alright. She’s got her “udder” already, the machine ought to detect the mass and attach to her properly. It’ll just hook on, notice everything is set, end, and she’ll be out in no time. The metal tubes slithered out of her line of sight due to her enlarged tits, then her blood ran cold as she felt a distinct coldness somewhere further down, on her gut.
“Error: Cow udder not detected. Correcting.”
She felt four simultaneous pinches. “No! Don’t f-fffuh...Fucking-” As before, Cassidy’s mind began to be overwhelmed by that wonderful feeling of growth. However, this time was not consensual. Cassidy fought with the numbing euphoria, biting her tongue to shock herself out of it, or at least keep herself lucid. “S-stop procedure. Machine! Stop! Procedure!”
Damnit, why hadn’t she set verbal overrides?! The burgeoning mass quickly began to compete for what little space was left, pressing into her lower breasts and her legs as it continued to grow. Soon, her upper breasts were getting shoved into her face, and she felt half of her newest asset flop out past her restrained legs.
There was nothing she could do but wait for the procedure to end. How long had it taken last time? The machine kept pumping more mass into what she could only assume was an udder, causing the pressure to start becoming painful as it tried to reach its full size while constrained between her legs.
Finally, the pumping slowed to a stop. “Seeding lactation.”
Four simultaneous thumps like last time. Which meant she was producing twice what a dairy cow should produce. Great. At least the external sensors were still dead and the only step in the procedure was udder enhancement.
