Non-Canon Omake: Pet Training

A/N: As the title says, this is a Non-Canon Omake that the commissioner had me write. An AU of an AU of an AU. Enjoy!

-x-X-x-

They back Marge's Ford Taurus up into the Dursley driveway and partway into the garage before opening up the back. Can't be having any of the neighbors seeing anything untoward now, after all. The Dursley Household is a perfectly normal household. Heh, once upon a time, that had been a statement born of a desperate need to appear normal while living with a pair of witches who were decidedly abnormal! Now though, it was more a statement of amusement, as everything had changed, flipped upside down in the Dursley Household.

Indeed, as Marge puts her car in park and pulls her hefty frame out of the driver's seat, Dudley and Petunia are the ones engaging in 'freakishness'. Both holding their wands aloft, they flick and swish and murmur 'Wingardium Leviosa' under their breaths as they float large dog kennels out of the back of the Ford Taurus and into the house. As they do so, Dudley gives his Aunt Marge a welcoming grin and a nod, while Petunia gives her a smile.

"It's so good to see you, Marge. I hope these two bitches didn't give you too much trouble. Though I'm sure you had them well enough in hand from the very start, what with your expertise."

Marge just throws her head back and laughs, while they all move into the house proper, only stopping once they reach the living room and can set the carriers down there. One might expect, since Marge was known to be a professional dog trainer and Petunia had used the word to describe a pair of female dogs, that there would be two mutts of some indiscernible breed inside of the pair of kennels. One would be wrong.

Rather, the 'bitches' that Petunia is referencing are in fact a pair of human women. Rose Evans and Lily Evans. And they have just spent the entire summer in the not-so-tender care of one Marge Dursley, spinster and professional dog trainer.

Why, one might ask? What could possibly cause two human women to be treated in such a debauched manner? How did it come to this? Well, that took a bit of an explanation. There were… certainly extenuating circumstances involved.

In one timeline, there was a Harry Potter who lived in the Cupboard under the Stairs, his parents killed by Voldemort. He would grow up to be the Savior of the Wizarding World. This was not that timeline.

In another timeline, there was a Harry Potter who lived in the spare bedroom with his addled mother, Lily Evans Potter. He would grow up to be the Savior of the Wizarding World, his mother would be cured, and great, GREAT misfortune would befall the Dursleys for their mistreatment of their relatives. This was not that timeline either.

In a third timeline, there was a Dudley Dursley, sent back in time by Delphini Riddle, to steal the magic core of his cousin and usurp Harry's place. He would then go on to steal Lily's magical core as well and gift it to his mother, ensuring that his aunt never had a chance to recover or be saved as he turned Hermione Granger into a silly little slut too busy with Crabbe and Goyle of all people to worry about making great magical discoveries. This was not THAT timeline either.

No, this was an off-shoot of another timeline. An alternate universe of an alternate universe. In this timeline, Dudley Dursley had been sent back not to deal with a Harry Potter, but a Rose Potter. The Girl Who Lived and her mother, Lily Potter. And oh, he'd certainly dealt with them. And Marge had helped.

"Well, they were a bit skittish and unruly at first, but a firm hand was exactly what these two silly bitches needed to train them into good girls after all. Here, give them a try."

The doors to the dog carriers are opened, and Rose and Lily slowly crawl out, wearing nothing but dog collars with tags hanging off of them. All very official-looking, all properly done up. Indeed, if someone were to find one of these bitches wandering the streets, naked and alone, why, one would hope they'd use the information on the tags to get them back to their rightful owners. Not that Dudley or Petunia ever intended to let their relatives out of their sight.

The looks on both Rose and Lily's faces cannot be described as happy or content. Indeed, they're both looking quite despondent about the whole situation. This makes sense, if one considers their head spaces. In this timeline, Dudley's travel had been a bit… messier. And rather than just let the version of the future where she and her mother came out on top die off as Dudley made more and more changes, Lady Rose Potter had made a somewhat brave and INCREDIBLY foolish move.

She'd tried to time travel as well, bringing Lily with her as they went back in time and attempted to meld with their old bodies. Their magicless, coreless, and in Lily's case, mentally addled bodies. To say Rose's plan to stop Dudley and save her timeline had failed would be an understatement. It had failed CATASTROPHICALLY.

These were the results of that failure. Their magic plundered. Their fabled wealth, properties, and titles… all plundered. Their noble family name of Potter had been dealt with and laid to rest, and the pair had been reduced to just Evans. Their potential allies, those who could have one day become their friends, lovers, and confidantes, had all been dealt with in amusing ways.

No one thought of Lily or Rose Evans anymore, outside of a handful of increasingly dated history books and the occasional sensationalist 'news' tabloid articles.

Rose remembered what she could have been, vaguely. She remembered the possibility of being a Lady Rose Potter in another world. If only her magic core hadn't collapsed, resulting in her being raised by Petunia as a good girl. She knows, deep down inside, that she is not Lady Rose Potter, the Savior of the Wizarding World, and that she will never BE that woman, that powerful witch. Indeed, she's just a good and obedient girl who obeys her cousin and aunt in all things. But still, the daydreams are quite powerful, leaving her distraught about what could have been.

Likewise, Lily Evans also has vague recollections of being Lady Lily Potter, of becoming the Minister of Magic after her daughter restored her, of pushing through reform after reform for muggleborns and indeed all the marginalized groups in the Wizarding World. The smartest witch of her age, she could have been. She could have done so much more, if her mind and magic had been properly restored to her.

But alas, her magical core had 'collapsed', and while that had 'cured' her of her mental ailment, it had also 'reverted' her to being a cowardly and obedient slut completely at the mercy of her nephew and her waspish sister.

These are the two women who crawl out of the kennels, the two 'bitches' that Marge has been training up all summer long. Rose, who took after her father but has her mother's eyes, has a shaggy head of black hair and glittering emerald green eyes… and a pale, nubile form with a pair of still-swelling breasts but also flared hips attached to an itty bitty waist that are just begging to be bred.

Meanwhile, Lily is the obviously more voluptuous of the pair. Not only do her breasts very nearly drag across the ground as she crawls, only avoiding touching by the thinnest of margins, but her hips are so abundant and wide that she has to wiggle her way free of the too-small opening to the kennel, a somewhat pathetic and decidedly dog-like whine leaving her lips as she does so.

Once the two bitches are out and before them, Marge grins, continuing on where she let off. First, she points at Rose and then Lily, naming them both.

"This one responds to Cunt. This one responds to Bitch. They'll both follow your commands… if they know what's good for them."

Rose and Lily keep their eyes cast downward, as Dudley chuckles in amusement and nods, stepping forward.

"Cunt, Bitch… Heel."

Immediately, both Rose and Lily drop their asses to the floor, sitting up but also sitting down. No longer crawling or on all fours, they stare up at him, their lips curled downwards in despair, but their eyes focused on him and his words as they await further commands. Chuckling, Dudley nods slowly.

"Good girls."

Stepping forward, he runs his hands over both Lily and Rose. With them displaying themselves for him like this, there's no need for him to worry about not being able to reach. His hands grab and squeeze two very different sets of tits. Aunt Lily's breasts are ginormous after all, especially when compared to her raven-haired daughter. Both of them whimper in the exact same way though from the contact, heh. Like mother, like daughter.

When his own mother steps forward, Dudley gives her a grin and a nod and moves to just Rose. His hands fondle her nubile young breasts for a moment, but admittedly, he's only half paying attention to what he's doing with Rose. He's much more invested in watching his mother, formerly magicless and left behind by the red-haired bitch in front of her, now toying with her younger, always more successful sister's tits.

Sneering down at Lily, Petunia grabs hold of her nipples and tugs them upwards, lifting the fat milk jugs her sister has attached to her chest up in the process, and drawing a keening whine from the bitch's lips. Lily squirms in meager protest but does nothing more. And yet, that's enough for Petunia to sneer harder and pull a hand back, only to deliver a harsh wallop of a smack right across Lily's humungous rack.

As the red head shrieks and falls on to her side, Petunia laughs at her rather cruelly.

"Bad dog. Stay still."

Slowly, Lily raises herself up and gets back into the Heeling position. This time, she doesn't squirm when Petunia returns to playing with her, drawing a wicked grin from the other woman.

"Good girl. That's better."

Rose, meanwhile, is not ignorant of what's happening to her mother either. She'd been moaning softly with her back ramrod straight and her chest jutting out into his hands as he toyed with her chest, but when Lily gets punished, she'd jolted as if to move to help her. Dudley had been prepared for that of course and had pinched down on Rose's nipples a second before she'd instinctively tried to move from her place.

The result was a sharp intake of breath, but to her credit… his well-trained Cunt stays where she's supposed to be. Dudley smirks at that, and begins to pull on those nipples, tugging her comparatively smaller breasts (to her mother's gigantic tits anyways) along with him as he leads her over to the couch and sits down with his legs spread wide.

"Go on, Cunt. Take it out and suck it."

There's no question what 'it' is. Rose shudders, but does as she's told, obedient and loyal to her Master, Dudley Dursley. His cock comes out and is in her mouth a moment later. Meanwhile, his mother isn't idle at all either. Seeing Dudley greatly advancing his 'play' with his cousin-turned-bitch, Petunia gets a vindictive look in her eyes and pulls her dress up. She doesn't even bother with orders. She just grabs her sister by the hair and shoves Lily's face into her crotch, forcing her to eat her out right there on the spot.

Marge, watching all of this, just laughs cruelly, enjoying the view. If Dudley's Aunt has any problem with what she's seeing, she certainly doesn't show it. Rather, it's pretty obvious that Marge sees nothing at all wrong with what's going on but is instead greatly amused by the sight. To be fair, the overweight woman had never liked Lily, even at their first time meeting back before Petunia had married Vernon.

It was a mutual hatred between the two of them, never getting along as girls, and never getting along as women either. Seeing Lily and Rose being treated like this now… well, it was everything the cruel woman could have hoped for. And she'd certainly enjoyed her summer training the two of them up for Dudley and Petunia.

For a time, there are no commands and no words spoken. Dudley is busy enjoying Rose's unenthusiastic blowjob and Petunia is busy enjoying Lily's tongue. Of course, neither bitch is very good at what they're doing, so the end result is that they both get ground down, with Dudley yanking on his cousin's unruly black locks and forcing her all the way down his cock and then back again, over and over.

"Gagkh! Gagkh! Gagkh!"

As Rose's choking fills the room, it's not long before he lets out a groan and cums right down her throat. Indeed, it's not long before Petunia also splatters her pussy juices all across Lily's face. With that done, Petunia pushes the dazed Lily back from her, letting the red head fall upon her back, her tits all a-jiggle in the process. Sneering down at her as contemptuously as before for a moment more, Petunia's entire face goes through a change as she suddenly smiles at Marge.

"Shall I make us some tea? Join me in the kitchen, will you? We'll leave Dudley to play with the girls."

"Of course. I'm sure a strapping young lad like him knows how to keep a pair of bitches like these busy, heh."

As the two older women leave the living room, Dudley just grins, dragging a gasping, coughing, hacking Rose off of his crotch and pulling her by her hair over to where her mother is. He lays Rose out on the floor right next to Lily, admiring the two dazed bitches for a moment. Rose, her face covered in his cum, and Lily, her face covered in the somewhat clearer pussy juices of his mother.

Reaching down, crouching over them, he grabs them both by the hair and yanks their heads together.

"Now kiss."

Moaning and mewling pathetically, mother and daughter do as they're told, making out and licking each other clean of their respective messes. As they do this, Dudley kneels down between his Aunt's legs first, and thrusts into her. Fucking Lily Evans is ALWAYS a treat, especially when he thinks about Minister of Magic Lily Potter. The bitch had ruined his and his parents' lives when she'd gotten her mind and magic back. Coming back in time and doing this to her and her daughter… it was incredibly enjoyable, to say the least.

More than that, Dudley had some extra grievances to work out on these two cunts, especially when they'd very nearly panicked him into a heart attack when they'd first come back to try and save their timeline. Not that it had mattered in the end. There hadn't even really been a fight. But realizing that it was the Rose and Lily from HIS timeline suddenly before him… had been quite the heart stopping moment.

Locking them down and having the goblins fuck their minds over magically, followed by having Marge train them in the muggle way all summer long had been Dudley and Petunia's response to the momentary scare. Now that it was passed, all was well… but that didn't mean Dudley wasn't going to fucking pay the duo back for scaring him in the first place.

And so, he fucks Lily viciously, pounding into her pussy with all his might and mauling her tits even more brutally than Petunia herself had just a bit ago. His aunt squeaks and squeals into her daughter's mouth, while Rose whimpers sympathetically, clearly feeling for her mother. Of course, that doesn't stop her from licking her aunt's pussy juices off of Lily's face like the trained bitch she is, nor does Dudley's rough treatment stop Lily from licking his cum off her daughter's face.

They are bitches first now, and women second. And in a very distant last place, they are the witches they could have been… but never will be now. Their possible futures are lost to them, and they've been reduced to this… a pair of pets for Dudley to make use of. Oh, and make use of them he will. After all, he and his mother have developed a Plan.

That's the real reason Petunia drew Marge away into the kitchen for this part. Not out of any sense of propriety or anything like that, but because he and his mom wanted to keep it a surprise. Grinning wickedly, Dudley thrusts forward one final time into his aunt and cums inside of her. As he does so, he takes his wand and taps it on her mound, just above her womb. A glowing magical glyph appears over her womb, something that Lily doesn't notice… but Rose does.

As Dudley pulls out of his aunt and shuffles over to his cousin next, there's an intelligent glint in Rose's emerald eyes that tell him she knows exactly what he's up to. As Lily is still lost in the throes of ecstasy, still cumming her brains out even after he's left her, only Rose really understands. Chuckling, Dudley slowly but surely sinks his cock into his cousin's depths, leaning over her and planting a hand next to her head as he stares down into her eyes.

"That's right, bitch. You know exactly what I'm going to do to you, don't you?"

Shivering, Rose silently nods, even as her tits jiggle with his beginning thrusts.

"Then beg for it, Cunt."

Rose's eyes widen, and her lips part, only to snap shut. Whatever defiance she had in her has been long trained out of her by both goblin magic AND Marge's professional bitch training. In the end, it's only a few thrusts more before…

"P-Please. Please, Master. Please knock me up. Please, this Cunt needs a baby. Please breed this Cunt. Please fill this Cunt with cum. Please, please, please."

Hearing Rose beg like that is music to Dudley's fucking ears. Letting out a laugh, he pulls back and grabs her by her legs, lifting them into the air so he can thrust all the deeper into her. He fucks her long and hard as she keeps begging, her mewling words filling the air and leaving him all too giddy with excitement. She begs and begs for him to breed her, until finally he does just that, cumming inside of her and casting the same spell upon her womb that he did on Lily's… all but ensuring that his seed will take then and there, in that moment.

Only then does Rose fall silent. Her emerald eyes stare up at him, blank and almost lifeless, except for a hint of judgment, of censure that she will never voice out loud thanks to her training. Smirking, Dudley gives her tits one last squeeze before pulling out of her. As he fixes up his clothing, he clears his throat and puts on his most commanding voice.

"Cunt, Bitch. Back in your kennels now."

The two women-turned-pets are slow moving, but they do it all the same, crawling back into their carriers and letting him close the doors behind them. Once they're secured, only then does Dudley move to join his mother and Aunt Marge in the kitchen, a wicked, satisfied grin on his face all the way out of the living room.

It's been almost a year to the day since Marge brought Rose and Lily back from a summer of training. It's the end of the next summer, in fact, which means Dudley and Petunia have to go about getting this little ritual done before Dudley is due to leave for his final year at Hogwarts. Still, they're in no rush. Everything is as it should be.

Lily and Rose stand there, naked save for their dog collars and holding their baby girls in their hands as Dudley and Petunia carefully and cautiously go about transferring the magical cores of the two infant witches over to Vernon and Marge. It's a sign of just how far gone the two Evans women are that they don't connect the dots behind why their cores just 'mysteriously collapsed' and they became squibs, to what they're watching happen right in front of them.

It's a sign of how obedient they've both become, that they don't even think of trying to stop Dudley and Petunia of robbing their daughters of their magical future. After all, Dudley is not only Rose and Lily's Master, but also the father of these two baby girls. He knows best… his word is law… he is to ALWAYS be obeyed.

And so Rose and Lily stand there and participate in the removal of their own daughters' magical cores by doing nothing to stop it. Soon enough, the deed is done, and Dudley and Petunia lower their wands with broad smiles on their faces as they gesture for Vernon and Marge to try out a few of the wands they'd procured from the old Potter Vaults.

A trip to Diagon Alley might still end up being in order, but at the same time, the two Dursley siblings now have Potter cores, so…

The reaction comes on both of their third attempts, and as Vernon and Marge hold up the wands, a light show erupts from the tips, making them damn near jump out of their skins before laughing in honest delight. In the meantime, Petunia has taken the now-magicless infants and places them in their cradles, leaving Rose and Lily to clap their hands politely as Vernon and Marge 'awaken' their magic, even at such a late age.

Dudley, meanwhile, chuckles as he steps up behind his two pets and reaches around to play with their hefty breasts. Rose definitely takes more after her mother now in body type at least, with motherhood agreeing with her and giving her a large pair of tits to fondle with and play with.

"You know, ladies… I think dad and Aunt Marge are going to be better at magic than the two of you ever could have been."

"Of course, Lord Dursley. You're absolutely right. Much better than us."

"Uh huh, Master Dudley. We really were rubbish at this magic thing. Master Vernon and Lady Marge are going to be so much better than what we could have been."

Dudley's grin only grows wider and more wicked as they immediately nod and happily agree with what he's saying without even thinking about it. Truly, the pair of bitches are absolutely perfect in comparison to what they were like in his memories of the previous timeline. Yes, they were so much better like this. So, so much better.

Moving his hands from their breasts down to their ever-wet cunts, Dudley fingers them both from behind as he and they watch Vernon and Marge play with their new magic in childish wonder.
