Moo
The beautiful morning sun rises over the milk mine, as it blankets the land in warmth and causes the morning rooster to let out it’s morning call. In a bedroom of the farmhouse a young changeling is busy shaking two lumps in the bed that refuse to move or awaken.
“Wake up daddy, it’s time for another day of work,” a voice nudges the red Amazonian unicorn awake, causing the lump in bed to groan as he is slowly awakened. “You too mommy,” she follows up by shaking the other lump in the bed that lets out the same reaction.
“Alright we’re up!” the two sleeping individuals shout as they throw the covers off them yawning and stretching only to see their daughter Sneak stand there with a big grin on her face.
“Morning sleepyheads~” she teases with her wide grin, which sets off alarms in both their heads after all they didn’t name her Sneak for nothing.
“What are you up to?” Magma asks, deciding to get straight to the point.
“What would I possibly be up to father?” she questions trying to act innocent like, despite the fact everypony knows she is far from innocent.
“Then why did you wake us sweetie?” Hollow asks stretching and yawning.
“I made you two breakfast,” she tells them. “What’s so bad about that?” she asks trying to see why they wouldn't trust their beloved daughter.
“That depends on whatever it is your scheming,” Magma points out with his words ringing truth, Sneak is always using ponies as guinea pigs for her potions or just flat out trying to fuck her father sometimes.
“Just helping you to get some fuel for today, a big order came in,” Sneak explains, showing the large order to them.
“Well….fuck,” Magma responds it will most likely take both him and Hollow all day to fufill this order. “So what’s for breakfast?” He asks, curious as to what his daughter made as she leads them to the kitchen.
As the two lovers get down they see quite the spread Sneak has set up for them; pancakes, fruit, toast. orange juice and everything else as part of a balanced nutritious breakfast.
“Ta da! Whatcha think?” Sneak asks before setting plates and cutlery down for them. Both Hollow and Magma can hear their bellies growl seeing such a tasty spread laid out, they take their seats before immediately starting to chow down. “I will take that as you like it,” Sneak responds, puffing out her chest in her own pride at them enjoying the meal she made.
In no time both Magma and Hollow finish their breakfast both laying back in their chairs with big grins and stuffed bellies full of food.
“I am stuffed,” Magma says, patting his stomach.
“Same although usually it’s with cum but with food it's just as nice,” Hollow adds.
“Glad you two enjoyed now get going we need that order filled,” Sneak says pushing them up and out the door.
“H-hey hold your horses!” Magma retorts as he and Hollow are pushed outside by their daughter.
Sneak slams the door as soon as they're outside.
“Phew I don’t know how long until those potions I slipped into their food activate,” Sneak sighs looking out the window to see her kicked out disgruntled parents walking to the barn. “Good thing I faked that big order too,” she mentions to herself giggling at the fact her plan has gone off without a hitch.
Inside the barn Hollow and Magma set up for what is more than likely going to be a long day of milking between the two of them.
“I swear we need to set up some sort of cap on what ponies can order,” Magma grumbles unaware that his sense of smell seems to be improving slowly.
“Oh don’t be so grumpy,” Hollow points out as she begins producing a lovely pheromone unbeknownst to her.
“I can’t help it because… you smell that?” he says cutting himself off now sniffing around wondering where this smell is coming from. While that is happening something is itching on the top of his head.
“What smell?” Hollow asks scratching her own head as she is feeling the same itch.
“You can’t smell it, it’s so obvious and smells soooo good,” Magma says as large horns begin to burst out of his head growing to become quite large, his muscles get more defined as well as his cock seemingly grows slightly larger and his nuts become fuller.
Hollow gasps in surprise at the sudden changes but soon undergoes her own changes, her own tiny set of horns, her breasts grow several sizes bursting from her top and leaking copious amounts of milk from them. Her body grows more plush, softer and more gropable too, her pussy seems to start drooling with it’s own fluid leaking like a broken faucet. And lastly several darker splotches appear all over her own body making her further resemble a cow pony.
The two blink looking at their new forms before Magma now figuring out that aroma that he is smelling, It’s Hollow’s pussy pleading to him that it needs dick stat! And in no time at all the two end up in some of the nearby hay both their clothes either being torn off and tossed aside before being naked and a hard red bull pony dick just inches away from a wet and ready cow changeling pussy.
Without wasting a moment Magma plunges himself into her leaky depths surrounded by the tight wonderous snatch he knows so well.
“Mooooo!” Hollow lets out as she squirts some milk out of her melons which bounce and around as he thrusts. He reaches down roughly squeezing her boobs letting out a large torrent of milk fire up into his open maw as he continues to pound her now drinking from her overly full melons while sating his needy cock with her equally hungry cunt.
Meanwhile inside the farmhouse, Sneak was busy cleaning up the dishes as her siblings made their way downstairs.
“Like where is mom and dad?” Minerva asks.
“Oh they’re helping me with an experiment,” Sneak says now drying her hands after doing the dishes.
“Willingly?” Belle questions.
“Somewhat,” Sneak responds with a toothy grin.
In the distance a loud mooing noise can be heard coming from the barn.
“Uh oh…” Hidden says only wondering what can be going on in there while simultaneously popping a chubby.
Back in the barn Hollow was bent over taking it from behind in her gushing snatch, Magma was grunting, squeezing Hollow’s thighs, butt and occasionally her boobs as he kept slapping his hips into hers and slinging as much dick as he can into her. Hollow was lost in her own pleasure, happy to be getting dicked down like a breeding sow mooing uncontrollably with each plap he lands and spilling some milk from her over flooded tits onto the ground. Each plap he gives further adds a mix of her vaginal secretions into the ever growing pool of fluid near their hooves. His thrusts are quite rough with him using his newfound strength to batter himself into her womb and constantly abuse her supple cunt with over and over seeing her as only a cock sock to wear to get off.
He grunts as she moos and both of them orgasm with him shooting ribbons of his fun juice deep into her womb flooding her with as much as his newly swollen sack can muster in one shot.
“Mmmmmoooooooooooooooooooooooooooo!” she howls out as she squirts her own juices all over his rod both of them cumming their brains out.
A few moments pass with both of them panting trying to regain their breath and as soon as they do they go right back at it like wild beasts once again driven by their carnal lust for each other.
Moments turn to hours as the constant mooing never ends and a seemingly endless cycle happens of Magma rutting her and then busting a fat nut only to rest for a moment or two and repeat. Hollow now is sporting a cum belly that nearly touches the floor which has a giant puddle consisting of cum, milk and vaginal juices. This goes on as they constantly climax over and over a breeding stud and his breeding sow fucking until both their respective genitals feel sore.
The night reaches and a howl is let out as he cums again his thirtieth orgasm before eventually his legs give out and he falls back passing out in a pile of hay his cock no longer plugging her cunt letting out an ocean of spunk. She on the other hand is soon propped up by her swollen belly and simply lies atop it letting sleep take her.
“Hooo boy they sure did a number on each other,” Sneak comments walking in to see what had happened now that the mooing had stopped being greeted with the powerful smell of sex and cum.
She stands over her two parents both spent and slowly begins shifting back to normal with their new additions fading away like they were never there.
“Well this is some good data, plus I think I may be getting another sibling or three,” she says with glee as she begins documenting the results.
