Inside Jeff's neighbours house, Charlotte, a 32 year old mother of two young kids, was busy prepping food for her two children before heading off to work. With their father having run off, Charlotte was left alone to look after her 5 year old Jacob, and her 4 year old Elise. It wasn't easy being a single parent, but at least her neighbours occasionally helped out if she had to work late nights and couldn't get any childcare otherwise. Whilst in the middle of making beef and cucumber sandwiches for her kids, Jeff hit the change button for the Chronivac to begin swapping the roles of humans and cattle.
"Hmm? I thought I felt a shiver just now." Charlotte mumbled to herself. While she wasn't totally aware of what her neighbour had just done, a change on that scale does leave certain things to happen. Even if it would all eventually be forgotten.
Deciding to ignore the shiver as nothing, Charlotte continued to prepare the sandwiches, unaware that she had already began to change and conform to Jeff's new world. Already, her slightly plump body began to gain fat, especially around her belly, waist and ass, which caused her shirt and pencil skirt to get tighter around her body. "Perhaps I should buy some new clothes. Feels like these ones are getting a little too small for me although I didn't buy these not that long ago. I should really start going back to the gym." Charlotte mumbled to herself. The ill fitting clothes were further exacerbated when her breasts began to get larger and larger, with a second pair of breasts slowly growing underneath her first pair.
Whilst in thought about her ill fitting clothes, her two children, Jacob and Elise trotted into the kitchen. Like their mother, they had also gained weight and their clothes, respectively a school uniform for elementary and a little sundress, were now far more ill fitting for them. "Mommy, when are we going?" Jacob called to his mom.
"Not now sweetie, Mommy's making your lunch for today so I'll be with you soon."
Despite what she said she would be doing, Charlotte find it increasingly more difficult to actually make lunch for her two kids. Her hands were slowly losing their ability to grab things as they slowly formed into hooves, along with her feet which her now bare foot on the hard kitchen floor. It didn't help either with Charlotte's skeleton shifting and changing to better fit the new form that humans would take. This also made it harder for Charlotte to keep standing on two legs, unlike her two kids which have already shifted to standing quadrapedal.
"Moooo-mmy, I want moo-ilkies." Elise cried which sent a weird feeling to Charlotte as her breasts began to lactate, and her nipples lengthened into teats underneath her very stretched clothes. In fact, their clothes were so stretched from all the accumulated fat, that they got torn and ripped to shreds from their body to to the pressure of their rotund and fat bodies.
"Not now Elise, Moommy has to... what has Mooo-mmy got to moo?"
With their physical changes having long since been happening, their mental changes began to happen as Charlotte's mind began to slowly lose it's intellect and intelligence, and be reduced to that of a grazing animal. Her two kids already had their minds begin to change with them both being hungry for milk, and now having even lost the ability to fully speak. Charlotte on the other hand retained some ability to speak at the moment.
"Mooo-ilkies, Moo-mmy give moo-ilkies." Charlotte mooed as she moved her now fully hooved hands and feet to walk on all fours towards her calves. Her body was almost fully transformed as her pretty pink vagina moved closer towards her anus and enlarged into a more ugly shape, fitting for a breeding female. Charlotte's fat belly hung low to the ground and her four giant, milk-filled breasts were exposed to her calves who both immediately began to suckled on her teats.
"Mooo" Jacob and Elise mooed in unison.
"Moo-ilkies, Moo-rink Moo-ilk." Charlotte mooed back as her speech and intellect were almost completely gone.
Around the three of them, their surroundings shifted from inside a surburban kitchen, to a large open field filled with other mothers or expecting mothers. In a neighbouring field to the one Charlotte and her calves were in, was various females that were neither pregant nor mothers, with one male human going around and mounting them. This male happened to be Charlotte's runaway ex, Mark. Although now the term ex doesn't really apply to cattle so Mark was Charlotte's mate.
Speaking of names though, long human names don't apply to livestock such as the humans, with simpler names or numbers being used instead. For Mark, he's simply names Biggie while Charlotte is named CeeCee. As for her two Calves, they haven't been named yet by the ranch owner bull yet, but like their parents, it would be simple easy names.
With them all now in a field and their new home, the last few changes happened as CeeCee's neck and skeleton fully changed, permanently keeping her on all fours. Her neck also changed, keeping her head looking straight forward, with it also lengthening to allow CeeCee to graze the grass off of the floor. Internally, all her organs had also changed with her now having 4 stomachs, and a ugly pink vagina that can take on the now larger male members of her species.
With all that done, the transformation was now complete, and with that, any trace of humans being the dominant species have also disappeared.
Now being unaware of any of this, CeeCee mooed and took a massive shit in the middle of the field, not caring to do it in private. Whilst doing this, her now 6 month old calves were still suckling her teats.
