She's lost certain privileges

Looking in the bathroom mirror, Kate hardly recognized herself. A lot had changed in the past couple days. At her chest hung four, ZZ-cup boobs, heavily engorged with a hefty supply of milk. But that wasn't all. Since her latest enhancements, her ears had been growing longer and floppier; like a cow's. Furthermore, her mouth had elongated into a muzzle of sorts, with even her tongue becoming longer and thicker. Her physicians assured her there was no physical damage or disfunction, that it was merely a side effect of of the bovine hormones in their secret formulas.

In her reflection, Kate no longer saw the beautiful model she once was. She just saw a cow, an animal pretending to be human. When Kate opened her mouth to speak, her opposite did the same.

"Moooo." she let out. She still found herself unable to speak. When she was captured, she was subjected to intense hypno-therapy. No matter how badly she wanted to, she was incapable of saying anything other than "moo" until given the key phrase.

Kate got down on all fours and crawled out into the main room of her cell. The weight of her "udders" was sometimes too heavy for her to stand, so quadrupedal locomotion became gradually more common.

She was still allowed her own room, granted with a few concessions. For one, no more books. The lack of books as entertainment was both a punishment for her escape attempt, as well as a preventative measure. Without a heavy stack of books, it would be harder to make an improvised blunt-weapon like before. Second, her television access was limited as well. The only programs she was allowed to watch now were pornography.

It wasn't all bad, though. Her sex toy collection was untouched, probably because orgasms still correlated to a higher milk output. Between that and the porn, she was still able to entertain herself with sex.

The real changes came with the milkings. The pumps she broke were replaced with industrial grade equipment, as well as extra nozzles for her second set of funbags. Even if she could conjure the strength and sheer volume of milk needed to break it, her new body would never survive the experience. Her new boobs were every bit as sensitive as her originals, and just as productive. By combining a number of factors, such as full engorgement and numerous, successive orgasms, Kate's body could produce up to four gallons an hour. The process was so frequent and so taxing, she had little time or energy for anything that wasn't eating, drinking, sleeping, or pumping more milk.

There were times she tried to fight it, the urge to milk. She was afraid of only being good for milking. But it didn't last. Within an hour, her tits felt like were going to burst. Any longer than that, they'd simply spray their payload uncontrollably, and at a rate still too slow to ease the pressure.

Kate plugged her thick, tender nipples into the mouths of the milker inlets and activated the machine. Within minutes, her pussy became sopping wet. She took one of her vibrating dildos, the biggest in her collection, and stuck it deep into her eager sex. She could have sworn it was getting easier, shoving something that large into her hole. But it wouldn't surprise her. Those hormones had ruined her perfect tits, her ears, and her gorgeous face. Why wouldn't they do the same to her vagina?

The cowgirl mooed violently, her vaginal muscles clamping down on the buzzing piece of plastic. She was already there; a thin waterfall of girlcum leaked from her crevice.

This truly was her life. Her failed escape attempt had shown her just how impossible it would be to leave. And even if she could, where could she go? She barely looked human anymore. People probably wouldn't even recognize her as Kate Upton. Plus, her quad of oversized tits would never let her live a normal life. Milking and fucking were all she was really good for now.

These thoughts echoed in the back of her mind as the device suckled from her. Was it ideal? Of course not. But was it that bad either? She had food, air, water, shelter, and sexual satisfaction. She never had to worry about clothes, or money, or paparazzi. Even fond memories of her husband or daughter couldn't compete with the joyous feeling of a let-down.

Kate didn't know if she was losing her mind to the captivity, isolation, and/or endless climaxes, and now she'd stopped seeming to care.
