Circuit Breaker cursed softly, pulling back her hoof as she felt a shock travel up it into her body. The mare rubbed the frizzled dark purple fur of her leg and scowled at the electrical box, sitting innocently before her. The unicorn mare would normally use her magic, but the damage to the farm’s electrical breaker needed a more steady touch, and Circuit’s hooves had always held firmer than her magic in the end. Circuit’s brown eyes scanned the box for anything out of place, satisfied at last she closed the grey steel box and flicked the power back on. The box hummed happily now it was fixed, the odd wheezing it had done before long since forgotten, the purple mare gave a triumphant laugh and jumped down.
“Job done!” She proclaimed proudly as a bright yellow, straw coloured mare approached her.
The mare was called Sweet Milk, a unicorn oddly working alongside her Earth pony family, they maintained the most popular brand of milk around Baltimare. Sweet smiled up at Circuit and she felt his heart do a little flip for her, she was so beautiful with her golden mare, groomed perfectly, her braided brown tail and mane flowing behind her and her cool water blue eyes twinkling up at her. Even a straight mare would bend their rules for her!
“Ah, well done Miss Breaker, an excellent job… I had thought you exaggerated with your boasting of getting this done in mere minutes but you held firm… Not even ten minutes and she sings! Now we can get the pumps working once more.” Sweet said excitedly, her soft accent rolling off her tongue smoothly.
“Not a problem Sweet.” Circuit said scratching behind her head grinning “It was pretty tricky but I have plenty of experience.” She said smiling.
Sweet stepped up closer to Circuit “Yes I can see… My father, the stupid man, tried to fix it… You saw how that turned out, and easy fix if not for his idiocy… He has been… Severely punished however.” Circuit suddenly gulped at Sweet’s tone, which was no longer sweet ironically.
“Well… I best head off now the jobs done I’ll organise the bill and…” Sweet covered Circuit’s mouth.
“Oh, no, no! We will pay you now! So much easier for both of us yes? And I also wish to give you a… Bonus… For such a fast work despite my father’s best effort to hinder you!” Sweet chimed.
“O-oh… Really it’s fine.” Circuit said bashfully.
Sweet reached up, stroking Circuit’s brown pony tailed up mane soothingly “No, I insist, come, please, follow me!” Sweet said her horn flaring with a swirling purple magic as she grabbed hold of Circuit, leaving her no choice but to follow or be dragged by the other mare.
Sweet led Circuit out the side building attached to her house, a large garage to be exact which had assorted various shelves of farming tools and odds and ends from various hobbies, most likely. The pair cross from the garage to a large barn-like building, likely for the cows that were being kept in the fields to sleep and be milked in. Sweet smiled back at Circuit and, for some reason, the comforting smile made her feel comfortable… She was safe with her.
Sweet pushed the barn door open and dropped her magic letting Circuit stumble after her. The smell of dry hay wafted through the barn, the whole room was strewn with straw and bags of hay for the cows. Along one side was a row of milking machines, docile and dead as no cow was present to be milked. Sweet stepped over to the clear side of the barn by the milkers.
“One moment Circuit whilst I retrieve your bonus for such a good job.” Sweet said with a grin retreating behind the large machines.
With little else to do whilst the mare waited for Sweet to return, Circuit approached the row of milkers. They had various little suction cups for the cows teats, noticeably the base had what looked like a soft squishy foam… Circuit wondered if that was so it was more comfortable and possibly even pleasurable for the cows… Circuit stepped closer to the edge leaning over to see. The suction cups were rather small just big enough for the udders… But Circuit felt an odd craving for them to be attached to her… Her eyes felt heavy as she stared at them, it would feel nice wouldn’t it… To be softly suckled by the machine, kneading out gallon after gallon of milk…
Circuit blinked backing up, banging into somepony “Oooh… The resilient type huh… Very well, we’ll do this the hard way.” Circuit just registered Sweet’s voice before something freezing cold slipped onto her horn.
This wasn’t the end, Circuit felt her hooves being force down by magic before restraints were tied to her back legs, keeping them stretched outward, making movement difficult. Finally, as Circuit opened her mouth to speak a bright green face mask was tied over her mouth, silencing any sound she tried to make.

“There we go, no need to fight this little Circuit, it’s just your bonus after all. A good time… Here on the farm.” Sweet said circling around to be in front of the mare.
Circuit whimpered softly trying to move away from the crazy mare “Where are you going Circuit… Isn’t this what you wanted? You WERE hitting on me, no, you wanted to fuck me right?” Circuit blushed, the idea HAD crossed her mind… A few times “And besides you will be happy here… Just like my father. You’ll join him soon, as another wonderful bit of livestock!” Sweet said as she levitated over a silver cow bell on a purple strap.

Circuit backed up, turning her head as he tried to avoid the bell as if it was threatening her life, but she wanted to stay stood up so she could not avoid it as Sweet tied the bell around Circuit’s neck. Circuit heard it instantly, making her eyes widen. The chimes of many cows mooing with soft bells ringing back and forth. Circuit’s head began to buzz and she closed her eyes try to focus.
[I]“I am livestock, I need to be milked. Milk me, milk me! I am Livestock, I need to be milked. Milk me, milk me!”[/I] The chant was quiet in Circuit’s head but still audible, unknown to the mare as soon as the strap has closed around her neck the bell has started to glow… Brainwashing her with its soothing song… And changing her in so many ways.
Circuit felt the cold steel on her horn lift up off her head “No need for this now.” Sweet said with a chuckle.

Circuit tried to work his magic as Sweet undid the gag as well from his mouth but Sweet spoke first “Feel that Circuit…? Your breasts are starting to swell, they look so pent up and full.” Circuit opened his mouth to argue then the arousal hit him, the chanting in his head picked.
Circuit felt needy… Pent up, full! She… She needed milking, the idea of those little suction cups around her teats made Circuit feel excited, Circuit felt something else she hadn’t before, a long warm shaft dripping with pleasure, it felt nice to have. Circuit felt her breasts churn with warm liquid… Circuit didn’t even try to hide the excited moan that escaped her lips. As Circuit thought of those lewd ideas, she failed to notice the fading sensation of her horn on her head, the spiralling horn on the mare’s head began to shrink back into her skull… Whilst on either side, above his temples, two white budding cow horns began to sprout, growing in size as her horn shrank in size.

Circuit’s horn was soon lost in her mane then gone forever as her new horns grew up out of her head. Circuit’s tail hairs began to retreat as well, forming a long curling thin purple tail with a faint sprout of brown hair on the end, the only evidence of the mare’s former tail. Also, along Circuit’s body various lighter purple spots were appearing in her fur, like a cows black spots.
Circuit gasped again, the building was getting worse… But there was also a tugging on her breasts as the warmth grew. Circuit managed to tilt her head to look at her overly large breasts hanging with her new member erect at the front, jumping at her as the pleasure washed over her mushy mind. They looks a lot like a stallion’s genitals but hanging lower and bulging with much more liquid.
“Look at that, your teats are coming out already!” Sweet said happily and Circuit panted looking at the four bumps on the base of her balls, a sliver of Circuit’s mind registered the loss of her leg restraints, however her legs had locked into place as if the position was now her favourite.

As Circuit’s teats grew out she began to feel the damp warmth from her rump area faded, a soft tugging and stretching as her vagina sealed over itself, was she even a mare anymore now?… N-no… Circuit was a cow… A needy pent up cow that needed milking, her heavy churning udder was full of delicious warm milk.



As Circuit thought this her new penis began to shrink back into her, sinking into her new udder, being swallowed as the muscle was used to finish the expanding udder. Circuit’s penis faded from existence, replace by a very heavy and very full cow udder. Sweet grinned watching the former mare dissolve before her, she had been even weaker minded than her father! Ah well it made it easier.

“Now… Who want to be milked?” Sweet asked as her horn glowed. Circuit nodded eagerly panting as she followed Sweet’s gaze. Circuit’s eyes landed on a bright pink butt plug, floating towards her

“Now what do cows say when they want milking?” Sweet asked before ramming the plug into Circuit’s rear end, pushing it in and out smoothly.

Circuit’s eyes rolled up into her head and she let out a long loud “MMMMOOOOOOOOOOOOO!” An excited cry likely heard around the farm… Signally a new cattle to the herd.

“Good girl, now let’s get you flowing.” Sweet said clicking the butt plug on so it began to buzz softly in Circuit’s plot, leaving it as deep as it would go inside Circuit. The cow mooed happily as her teats began to drip with milk “You look ready, okay Circuit into your paddock!” Sweet ordered pulling the bars back to allow Circuit inside.
Circuit trotted briskly inside, her butt quivering from her toy, the bars closed and she jumped up onto them, presenting her leaking udders to Sweet

“So eager now, good girl. Yes I think you can be milked, good behaviour pays off after all. Here we go.” Circuit let out another happy moo as, one after the other, the four suction cups were attached to her four new teats, they began to buzz and clench, already streams of milk flowed quickly out of Circuit.

If any of the former mare remained in Circuit then, it was soon washed away by the constant pleasure of her udder being emptied “Good, now with two new cows on board we might be able to catch up on our quota my father slowed us down on. Well done Circuit you’ve done so much for us!” All Sweet got was a content moo from Circuit “Yes… You can stay in the machine ALL night if you want… Have fun.”
It was a very sweet night.
