Not immediately, but there is no escape

Sandy had beautiful hips.

Josefina wasn't sure why she noticed now, or why it was suddenly so important, but she could hardly tear her eyes away from her daughter's rear. Something about them, nearly as wide as her own, transfixed her in the best way, leaving her unable to do anything but stare at tight twenty-year-old's butt.

Sandy, for her part, was also frozen in place, though for a completely different reason. She had watched with what she thought was horror as her father was turned into the milky hucow that now mooed and moaned just a few feet away, but now seeing the end result and feeling an increase in pressure in her own chest, she couldn't help but envy the dumb cow, no matter how much she fought against the thought. Still, she resisted as best she could, even when an orgasmic flood of girlcum gushed out of her transformed father's pussy.

"Come on Sandy, you can go right over here," Maggie said, grabbing her sister's wrist and tugging her towards another milking station next to the occupied one. Suddenly realizing what was going to happen to her and afraid she'd meet the same fate as her father, Sandy struggled fiercely against her younger sister.

"No, Maggie, don't do this, I don't want to be that. I don't want to become that! Why are you doing this?! Mom, help me, don't let her!!" Sandy screamed, fighting harder the closer her fiendishly strong sibling brought her to the pump.

"You're so silly, Sandy, you already are that. You just need help seeing it. And I'm doing it because I have to. Otherwise, I can't be a good little heifer. And I don't get to cum. And I need to cum. And feel good. And get milked. I can't wait to be a good little heifer. And then maybe someone will make me a good little cow, pump me full of thick splooge and make my belly as fat as my tits. Oh fuck, you don't even know how bad I need it, Sandy. But you will soon."

"No no no no no! I won't, you can't!! Mom, please, do something!! Help me!!!"

"Oh, yes Momma, please help! I was worried when Daddy lost his, but now you can make us into good little cows! Oooo, look at that big thing grow!" Maggie squealed with delight, her sudden support of getting their mother's help surprising Sandy until she turned and saw exactly what kind of 'help' Sandy meant.

Pressing obscenely against the already tight fabric of Josefina's shorts was the huge imprint of a growing cock, one that was rapidly outpacing the shorts' ability to contain. The girls watched as their mother moaned and bucked her hips, responding to the newly instinctual need to rut something embedded in her brain. The mature blonde's hand quickly pulled her denim shorts open, allowing the log of meat to flop out and hang between her gorgeously thick thighs. Sandy and Maggie watched with horror and open desire respectively as the breeding tube continued to expand getting longer and longer while still almost entirely soft, until it reached their mother's knees. Now with less in them, the girls could also see two huge balls pressing out against the fabric, no doubt sloshing with seed. The sisters were so transfixed by their futa mother's cock that they barely noticed her tits swelling up a bit more and her face elongating slightly, giving her just a hint of a muzzle.

"Momma, you should breed Sandy first, show her just how good being a good, milky girl can be. I bet once she feels how good that big cock is, she'll love it." Maggie's words barely registered with her sister, who was too busy staring down the slowly rising penis with her mind swimming with conflicting thoughts. She was so dazed that she didn't even realized her sister had fully pulled her into position until the cuffs closed around her wrists, holding her in place.

"Oh, silly me, I should have taken your shirt off first. Oh well, we'll just pull it off NOW!" Maggie exclaimed, ripping Sandy's shirt in two and revealing the full size of her new boobs. The two huge spheres were getting larger, but were doing so extremely slowly. The barest hint of milk was accumulating on one of her nipples, but it was barely anything compared even compared to the dribbles that stained Maggie's shirt. Still, Maggie quickly positioned the suction cups over her sister's nipples, not turning the pump on just yet.

"Sis, you've got to stop holding back. You're going to be so mad at yourself for not letting yourself have this. You need to just let the milk come in, then you can have big, giant titties, like me!" The encouraging girl swiftly pulled her own top off, letting her much larger breasts bounce freely and sending jets of milk spraying out. Maggie cooed and squeezed her tits, making her cream flow faster, shuddering with bliss as she did. "Oh, that was so close. I'm almost there, I can feel it. Come on Sandy, be a dumb cow for me so I can cum. I need to cum, please!"

"Maggie, no, please don't. You'll end up like Dad, is that what you want? To be a stupid cow, just squirming and cumming and mooing like a brainless slut?!"

"YES!" Maggie exclaimed with another shudder of anticipation, much more violent than the last one, shocking Sandy to silence. "Yes, I fucking do! I came out here last night and tried to milk myself into oblivion. You would have come out here and found me laying in a puddle of my own cum as my tits were drained for the thousandth time. But I couldn't, and I want it so bad! I don't care if Daddy gets turned into a moaning whore, I don't care if Momma grows a fat dick, I don't care if you end up a moo-slut, I don't even care if I end up stupid and useless for anything other than getting fucked for the rest of my life. That sound fucking amazing and I just want to CUM!! Get my fat tits drained forever and feel a hot dick in my cunt!"

Maggie suddenly stopped shouting and smiled and Sandy froze as she felt her mother pull her pants off of her wider hips, revealing her wet snatch to the world. She could feel the heat coming off of Josefina's cock, now hard and pumping with blood, as the organ pressed gently at the entrance to her pussy but not pushing inside. Sandy was frozen with fear and helpless need, and couldn't do anything other than watch Maggie sashay over to another milking stall across from her and hook herself up, turning on her own pump and moaning with bliss as the suction went to work, pulling a small but steady flow of milk from her tits.

"Don't worry, Sandy, Momma's going to take good care of us. All three of us. Now be a good sister and turn into a cow so I can cum my brains out!"

At that moment, Josefina couldn't take it anymore. The heat from her daughter's pussy was too enticing and the urge to breed was getting stronger with every second. With deceptive casualness, she flipped on the pump attached to Sandy's large chest before grabbing her by the hips and pushing in with a moan.

"MMMOOOOOOOOOO!!!" In an instant, Sandy's resistance was shattered and she screamed a joyful, animalistic moo. The terrifying combination of blissful suction on her breasts pulling out the first real spurts of her milk and a thick dick meant for breeding pushing into her fertile cunt broke her and brought her cow out in full ****, ruining any chance she had of restraining or holding on to herself. Her eyes rolled back as she came and the full extend of her changes washed over her.

Her body took on the same properties as her former father: hooves instead of feet, a long tail, pink hair, a slightly elongated face, and absolutely gigantic breasts gushing with fresh hucow cream. Her mind hollowed out, accepting the fact that being a big-titted slut of a cow girl was the only thing she was or ever would be. The tiniest fragment of her former self lingered until a huge load of cum, courtesy of her groaning, thrusting, and fucking mother, washed the very notion of resistance away. That small part of her wailed in despair, but the rest of her was too busy mooing with happiness as her spurts of milk became a stream and she lapsed into a cycle of lactation and orgasms.

"Oh fuck that's hot. Shit, yes Momma, breed her with your big dick. Come breed me, fuck both your daughters into your own little hucow cock sluts," Maggie moaned, massaging her overfull breasts as they got bigger and bigger, full to bursting with sloshing milk. They surpassed the size they had reached the night before, never stopping as they outsized her head. Her hips widened too, making her ideal for breeding and birthing. Still, the pressure never released and Maggie became more and more ****, until she was pleading with the voice in her head for its promised relief. "I need to cum, please let me cum. I did it, they're like me, brainless cunts only good for their milk and holes. Now please, please, please let me cum. Let the good little hucow cum. I'm a slut, a milky slut, a milky, mooing, heifer slut."

"Good," the voice finally said, making the nearly broken Maggie jerk with pleasure, brought to the very cusp of her peak and left there for agonizing seconds. "Good. You may..." Maggie hung on the brink, ready to throw everything away just to reach her climax. "Cum."

Instantly, Maggie flushed, her tits surged with growth one last time, her face scrunched up, and she let out a pitiful, tiny 'moo'. Then she came, her virus-tortured body thrashing madly as hours of pent up pleasure wracked her. Her breasts bounce, jiggled, quaked, and rippled, while torrents of milk gushed out of her fat nipples, producing an untold amount of milk. Maggie sobbed with joy and relief as she drooled onto herself, delicate cow tail and matching ears sprouting from her body and small twin horns appeared just as her mind finished its gradual descent towards orgasmic insanity, leaving Maggie just conscious enough to revel in the feelings constantly wracking her.

"F-fuck me, M-M-Mooo-Mommaaa~" she moaned, her thrust out ass pleading for attention from the woman that was still her mother only in name. The toned and curvy futa wasted no time in plunging her throbbing shaft into Maggie's soaked depths, easily bottoming out despite the huge length of her cock. Maggie only came harder, her body eternally quivering as the reward given to her by the alluring voice in her head held her in its grip.

She had just enough presence of mind left to look over at her former father, who was being milked happily with a dumb expression on her face, and to her sister, who had fought so hard to resist being turned into the happy, stupid, mooing cow she undeniably was now. The knowledge that she was responsible for that, that they were only like this because of her, only made Maggie cum harder, milking the shaft in her cunt for its impregnating gift. The explosion of wetness and heat that hit her moments later as her mother came deep inside her was heavenly and was what it finally took to knock her into a half-conscious daze, leaving her hanging in the barn alongside her family, cumming gently as her enormous teats were drained.
