*Ominious theme plays in the distance.*
On the night of Nightmare night a certain red unicorn was snoozing peacefully in his bed unaware that creeping in was three of his bugling daughters. One was smart and cunning with a bit of a daddy crush hoping to finally be able to taste the forbidden fruit her mother had for so long. The other was her rival and a bit of a slut who’d fuck anything that give her the time of day but mostly wanting to taste her own fathers peen. And the last one was a good little daddy’s girl or so she appeared with a sour attitude but one hell of a rear. They scampered out carrying the slumbering unicorn out the door and to the barn.
They set him down on a pile of hay as the first one began to work to create the serum that would grant the first two’s desires, as for the third one… well she’s only doing it cause she’d get paid and there's this cute dress she wants.
“C’mon Snape wannabe are you done with the serum yet!?” Queenie complains.
“No tits for brains I’m not, these things take awhile,” Sneak fires back.
“Gaaaah this is like super boring though!” Queenie continues to whine as Serenity does nothing but try to ignore her bickering siblings and files her nails.
“I need to get the amount of ingredients right otherwise it might have adverse effects,” Sneak explains. “It could turn dad into a werepony or a batpony,” she adds.
“And turning him into an incubuspony without him knowing or even saying okay is totally fine?” Serenity chimes in dispute.
“Well… maybe but I gotta get it right and make sure nothing goes wrong plus Mom loves wild crazy sex with him,” Sneak points out.
“But I thought this was suppose to make him wanna fuck us!?” Queenie whines and huffs.
“It will considering he will have a super powerful boner and since mom is busy she won’t know until she shows up that we may have had a round or two,” Sneak explains. “But one wrong move and we may not be able to reverse the effects and he’d be stuck like that,” she finishes throwing specific amounts of ingredients into her brew.
“And you wonder why daddy has the whole no incest rule,” Serenity states out loud.
“Hey you're just as guilty helping for some extra bits,” Sneak calls her younger sibling out.
“Well Flanksworth hasn’t paid yet and there is a cute dress that is just to die for!” Serenity exclaims.
“Riiiiiight, look I’m gonna go get an ingredient I think is in the house and then this serum should be done,” Sneak tells them before taking off back into the farm house.
With the mischievous curiosity of a cat Queenie wanders over to the equipment before grabbing a random bottle and dumping it into the batch nonchalantly.
“Queenie what are you doing?” Serenity questions her sister's blatant attempt.
“Just making sure daddy has enough sexual stamina for me, mom and old snape,” she admits before putting the bottle back and walking away whistling innocently as Sneak comes back and continues her work.
With precision Sneak soon finishes the serum which is a light purple color rolling around in a small potion bottle.
“Alright it’s done!” Sneak cheers happily as she picks up the fruit of her labor. “Now let's test this out Queenie hold dad's mouth open,” Sneak asks her to which Queenie rolls her eyes at.
She grabs his mouth mid snore, careful not to wake him up as this will be much harder to do and Sneak quickly pours the contents down his maw causing him to sputter and choke a bit at the sudden liquid entering his mouth but swallowing it nonetheless.
“Wha-what the fu-'' he begins to complain before feeling the effects take place. Two horns burst out from behind his ears curling slightly followed by two bat-like wings sprouting and growing from his back, his tongue growing in length and becoming more pointed and snakelike. Finally after growing about a foot or two taller, his cock grows about ten more inches and his balls swell to the size of prize winning pumpkins. Opening his now slitted eyes he stares at his kin with a fully erect member.
“Balls so full, need hole to empty!” he booms looking at the trio of changelings, his rock hard erection drooling with pre cum.
“Dammit Queenie why’d you have to fuck with the serum,” Serenity scolds her slutty sibling who’s licking her chops.
“She did what!?” Sneak screams in Queenie’s ear. “What the fuck did you do!?” She adds now utterly scared if she did irreversible damage before running over to her station.
“It’s no big deal, now sit back and let me have some fun,” Queenie responds as she disrobes, tossing her clothes and walking up to her now incubus pony father with open arms.
Seeing her approach the Magmabus approaches and pushes her to the ground before aligning his painfully throbbing member with her drooling slit and like a battering ram charges forward and enters her warm confines.
Serenity watches in aroused horror as Queenie gets plowed like a corn field by her transformed dad.
“Oh shit,” Sneak utters, having examined what Queenie emptied into her brew.
“W-what is it?” Serenity asks turning away from the scene at hand to see what has Sneak so distressed.
“She used all the Brocoke,” Sneak explains. “Normally it is used to increase masculinity and help with facial hair growth or muscle building,” she continues. “But when mixed with everything it causes it all to go to the testicles and has a minor effect to dumb the pony down,” she finishes.
“So is there any way to stop it?” Serenity pleads ignoring the throes of passion going on behind her.
“Well… it mixes in with his cum so he has to let it all out,” Sneak points out. “So he needs to nut like no tomorrow and he will keep fucking anypony and anything that he can get his hands on,” she tells her younger sibling.
“Then what do we do!? Can’t we keep up with him or at least you and Queenie?” Serenity exclaims.
“If she used a quarter of the can maybe but she used all of it!” Sneak mentions with a hint of worry. “He is now a sexed up monster pony who is gonna keep fucking until his balls are empty and I don’t think the whole town can sate him or even the princesses!” Sneak panics thinking frantically.
“There is no pony in all of Equestria who can help him!?” Serenity joins in panicking.
“W-well there may be two who can stop him,” Sneak ponders. “Listen you gotta make sure dad doesn’t go anywhere while I go get one of them,” she adds looking over to see Queenie’s abdomen bulging from the size of his dong.
“Wh-what! How!?” Serenity questions.
“By any means necessary, even fucking him,” Sneak tells her.
“Gaaaah f-fine but you owe me triple now,” Serenity caves as Magmabus starts orgasming deep in Queenie, bloating her with the first blast.
“Will do,” Sneak mentions as she sprints out the barn closing the large doors and running back to the house.
Sneak barges in frantically panting and looking around desperately before a voice chimes in.
“Sweet Celestia Sneak, what has you worked up?” The voice asks.
It was her mother Hollow who takes a sip of apple cider from her glass she was holding in her casual outfit of latex short shorts with a latex thong to match and a casual t-shirt that reads ‘Milf in training’ on the front and ‘waiting to be impregnated’ on the back.
“W-well promise you won’t get mad?” Sneak begins feeling like a child who got caught doing something naughty.
“Depends on what you did,” Hollow points out while taking another sip.
“Me and Queenie thought we’d make dad super horny with a special serum and of course we’d let you in as well so we turned him into an incubus pony,” Sneak begins her explanation before taking a deep breath. “But then Queenie dumped too much of something into the mixture now dad has turned into a sex crazed incubus monster with a huge cock and we need to make him cum out all the contents in his sack, otherwise he won’t change back and could go around trying to plant his pole in any hole!” Sneak finishes panting for air.
“I see… and you want me to fix you and Queenie’s mistake?” Hollow sternly asks, going to take yet another sip of cider.
“Well only two ponies could do it you and grandma Gossa-” Sneak is interrupted by Hollow’s eyes shooting wide and her grip on the glass increases to the point it shatters in her hand and soon cider and little chunks of glass fall to the floor. “Oh shit,” Sneak utters.
“How do you know about her?” Hollow asks, giving off a more ominous threatening vibe.
“Ummm I may have had Zeezee help out and enter one of your dreams to find out,” Sneak admits looking at the ground fearful of meeting her mother’s gaze.
“I see… so not only did you turn your father into a sex crazed monster but you invade my nightmares and found out about her!” Hollow scolds before groaning in frustrated anger.
“I was curious plus we all know nothing about our grandparents!” Sneak pleads her case before Hollow shakes her head and flicks the cider and glass off her hand.
“Come on then,” Hollow says, yanking Sneak by the collar. “I’m gonna fix your mess then just know you are so far up shits creek you're gonna drown!” Hollow finishes dragging her off to the barn.
Upon entering the barn the two look to see a passed out Queenie lying on the ground bloated with a huge cum belly, each and every hole was used as she twitches on the ground unable to move and even speak. Nearby was Serenity who was on all fours with a swelling cum paunch getting it from the back by the sex crazed Magmabus.
“N-no more cum…” Serenity weakly lets out as another fresh wave of it gets poured into her ass.
“Uggggh so you, Queenie and Serenity did this,” Hollow complains stripping down.
“They are getting punished too?” Sneak questions.
“Yup not as bad as you are gonna get and don’t forget Zeezee is getting it too,” Hollow finishes tossing her clothes aside before sighing deeply assessing the situation.
“Great…” Sneak mutters under her breath. “Should have figured I’d get this from Princess Art-” Sneak is cut off.
“If you finish that you are getting locked in here and you will have to drain his balls,” Hollow states flatly.
“Eep!” Is all Sneak lets out.
“Looks like if I’m gonna make him cum his brains out I’ll need to bust out the big guns,” Hollow figures closing her eyes and letting her magic take hold as a bright white flame envelopes her entire body practically swallowing her whole as her form begins to change.
Inside the blinding white flames her once short maned begins to grow long and flowing all the way down to her ass, her lips become more fuller then before and pouty naturally looking with her making it the ideal type of lips perfect for sucking dicks. Her already massive breasts swell from a large and nice FF cup to JJ cup sagging with some grace and firmness, her hips expand slightly looking even more worthy of bearing more children and lastly her bubble butt turns into a literal dump truck and can never seem to stop jiggling ever.
After the transformation the flames dissipate revealing her new form to which Sneak’s jaw dropped.
“Woah…” Sneak says.
“You can pick up your jaw sweetie,” Hollow mentions. “For future references your father has a weakness for three things: goth girls, milfs and bimbos,” Hollow states as she begins to approach the incubus pony.
“Noted,” Sneak responds.
“Oh Magma~!” Hollow calls out in a most sultry voice as she strikes a pose right as the sex crazed creature stops humping Serenity and fixates it’s gaze on her and his cock instantly hardens and throbs. “Why waste that great big boner and all that yummy baby batter on these young lust changelings when you can have something better,” Hollow suggests emphasizing each of her enhanced features. “I can let you use my mouth and you can feel me suck that painful erection and wrap my tongue around you and jerk you off with it,” she suggests letting her tongue fall out of her mouth which also had been changed to nearly fall on the floor but comes back when she wants to.
“Or how about I let you stuff my nice hot box, I think we can use another baby or three,” she adds, spreading her vag with her two fingers. “I can tighten it to be a perfect mold for your dick useless for anypony but you,” she adds to which the Magmabus pulls out of Serenity letting his cum coated dong lead him. Serenity sighs in relief as a flood of spunk begins to escape her.
“Or better yet you can clap my ass cheeks and stick that rocket of yours in the back,” she suggests turning around and getting on all fours and presenting her massive derriere to him wiggling it gently but causing the sheer mass of it to jiggle oh so perfectly.
Not holding back anymore Magmabus pounces and with a knowing grin plastered all over her face she instinctively pulls her asscheeks open exposing her asshole which was the target of his desire and with his hole seeking missile leading the charge plunges in and bottoms out instantly. Hollow moans and grins as she instinctively flexes her anal muscles to almost massage him, his cock like nothing before.
“I’ve been practicing using my muscles back there,” Hollow explains with a grin as she uses them to stimulate his intruder perfectly. “You don’t even have to hump,” she coos happily as the Magmabus struggles to even begin fucking her proper but unable to pull out with her applying enough force to keep him stuck. He grunts still trying to pull free to no avail, smacking and groping her wobbly rear to have her loosen up but she doesn’t budge if anything only being motivated by it.
With a fierce roar of pleasure to the heavens his trapped donger twitches and gets ready to unload some of the cumbersome cargo in his enlarged nuts, his flare expands further lodging itself even more as the rush of pleasure courses through and explodes deep inside her butt.
Hollow coos with glee which causes her to quickly and expertly flexes her muscles to easily milk as much of his nut butter as she can from this load with it working so well that Sneak visibly notes his sack shrinking in size.
“Mom, it's working, don't let up!” Sneak shouts to her.
“Way ahead of you dear,” Hollow reaffirms her belly already sporting a cum paunch, as she releases Magmabus from her anal prison.
He falls back landing on his still cushy butt still firmly erect but coated in his own jizz. Springing into action Hollow gets up and launches her lengthened tongue to grip around most of the length of his cock and begins jerking him off with her tongue before also adding in her massive mammaries to surround his meat in between her mommy milkers. She soon then moves her head down keeping her tongue wrappers around his length and begins sucking the first ten inches of his length. Cleaning off the mess he made in her booty hole while getting heaping helping of a whiff of his musky scent, she also was secretly releasing her own pheromones to make sure he lets out all the spooge he possibly can muster at a time to effectively drain his nuts properly. The sensation is only enhanced by Hollow’s more enhanced lips giving off a softer cushion and extra suction power too.
In no time at all he soon howls as he cums again giving her a taste of the salty treat he was storing in his balls. Her cheeks puff out like a chipmunk that has gotten its hands on some nuts to store for later and like the expert cock sucker that she is.
Sneak pays close attention noting that as her bimbofied mother sucks off her incubusified father that his sack is now half the size it once was.
Hollow pulls off leaving a trail of saliva connecting from her mouth to his dong and retracts her tongue before falling backwards and spreading her legs. Tantalizingly inviting him to take a dive into her slippery slide of a pussy.
And lead by his mighty meat spear he does pouncing on her but soon realizing that it was a trap with her locking her legs around his waist and pulling him till he bottoms out with her stomach slightly bulging despite the moderately size cum belly she is sporting.
He then tries to pull out to be in control but is denied by Hollow’s lower body strength which he constantly repeats getting a few inches out but then slamming it back home to hit her womb. She smugly smirks before wrapping her arms around his neck as he growls with the barn filling with echoing plapping sounds over and over. Hollow shakes her hips occasionally to firmly stimulate his rod further with her lust changeling training paying off in full.
“Let out all that baby batter dear,” Hollow whispers into his ear. “Just let go and empty yourself deep in your favorite cocksleeve,” she adds, licking her lips to add emphasis.
Much to his dismal joy his eyes cross as he experiences the Elden Ring of cumming his mind going blank, his balls shrinking rapidly as he unloads himself deep inside her and lastly his tongue falling out. Soon many of his eager swimmers begin their journey to find an egg to be fertilized beginning the battle royale to achieve the greatest victory royale.
Hollow’s stomach inflates even larger as he soon finishes dumping what little remained of the serum in her and thus he rapidly begins changing back into his normal self with all his new features receding and disappearing.
Having fully been changed back to normal he soon flops forward exhausted and spent beyond belief passing out between her breasts. She gives him a loving hug before shifting him over and pulling his now poorly abused meat out of her letting a flood of his spunk begin escaping.
“You did it mom!” Sneak cheers running over and giving her a hug.
“Was there ever any doubt?” Hollow responds, before getting up and walking over to a particular crate in the barn and opening it up. “Speaking of you need to still be punished,” Hollow points out.
“Wha-what!?” Sneak let’s out. “But what about Serenity and Queenie or Zeezee!?” Sneak pleads.
“Considering how Queenie got fucked into a coma and Serenity is blown up like a balloon I think they learned their lessons,” Hollow points out. “And I’ll get Zeezee in the dreamscape but as for you,” she mentions pulling out a chastity belt. “You will wear this magical chastity belt for three months,” Hollow mentions before dropping it in front of Sneak who looks on and gulps audibly.
“Uuuuughhhhhhhhh,” Serenity groans. “How will I make my shift at Flanksworth?” she complains.
“Don’t worry I got just the pony in mind who can handle it,” Hollow replies patting her bloated daughter's ass. “Now if you will excuse me I can use a sandwich,” she adds before heading out patting her big nut butter filled belly. Having worked up quite the appetite from her transformation and milking skills of her hubby.
Later on at Flanksworth…
“Fillies and gentlecolts!” the DJ announces. “Due to some stomach issues the Emprass could not make her shift tonight!” he informs them. “But don’t you worry because sent in her stead is a stallion who can handle any sort of pleasure, especially if it involves a stick shift, give it up for Hell Rider!” he introduces to which Yubie emerges in a thong shaking his hips and ass for the audience.
“Huh I see why Queenie and Serenity do this,” he comments to himself as he continues to seductively dance for the audience.
