It had been years since Golden’s visit to Canterlot, and since that day, the old Golden was dead, and a new Golden was born. Sure, she could play the role of the old Golden, she could fool her parents into believing that she was still the sweet dutiful daughter they had always known, but she was a new mare now. And that mare now had a mission.

Celestia had naturally granted her family the land they were promised, there was never truly any doubt about that. As Celestia had explained to her, it was a fixed point on the path arising to their Master's arrival. But there were things that they could control, could change to make their Master more pleased with their life. A difficult task, not least considering that it had to be a secret, from both her parents and the world at large.

But thankfully, she had a lot of help. The Slutprincess Celestia knew the importance of her mission to reshape Ponyville and was certain to support her as much as possible. She told Golden how to mix corrupting potions into the cider her family produced, whilst in no way was this enough to transform a mare outright, their tolerance for behaviour they once considered sinful, depraved or that of a slut would increase. Celestia was also eager to tell Golden all about the many different fruits of the Everfree Forest, particularly those which stirred lust and enticed sexual cravings. Not to mention there was also the fact that Slutprincess Celestia was filthy stinking rich and would pay for any of her needs. A rare occasion as Golden still loved a bit of good old-fashioned hard work.

She worked on her mission for years, decades, some in Ponyville would even whisper that Golden had lived for centuries. Whatever the case, she no longer fit the name 'Golden', not now that she aged to her most MILFest potential and wouldn't age any more. She took her new name Granny Milf and was eager to start acting like it. All in all, her days were happy, horny and exciting, albeit with one problem.

The Pears. A bunch of no-good prudes who'd moved into Ponyville and started to act like they owned the damn place. A bunch of religious nutters who'd go around shaming strippers, condescending perfectly good whores and covering up perfectly good outfits. It was enough for Granny Milf to tear her hair out if it weren't for one excellent thing.

Pear Butter, the fat-assed daughter of her rival, Grand Pear. Granny Milf had noticed with pride her son had won the heart of the future MILF, and they were growing closer and closer together, as she grew into a sexier and sexier woman. It was only too bad that her son would only get to fuck that colossal pear-shaped ass of hers three times, one for Big Mac, one for Applejack and one for Applebloom. But that was the way of the world, men like him only served to breed new mares for her Master's harem.

Today she was in her kitchen, frying some eggs with her right hand, and thrusting her own sexy ass onto her chair where a dildo of her Master's glorious cock had been fixed to. She did this every time when she was cooking, determined to carve out a place in her holes for her Master to take. She had came several times already, but she was shocked out of another one by a blue portal appearing in her kitchen, where two lovely sluts from her past, or more accurately, her future stepped out, hands on their hips, smiles wide.

"Now didn't you just turn out perfect?" Applejack said, a hand tracing her ass as she smiled.

Granny Milf smiled at seeing her future granddaughters, the fine sluts who had inspired her on her mission to be the perfect slut for her Master so many years ago. Still as beautiful and sexy as she remembered, and with that sensual glint in their eyes that promised so many delightful fantasies.

"Ah'm just following your example, trying to be the best MILF for my granddaughters. Ya want to fuck, ah promise Ah've improved a bunch since we last met." Granny Milf asked, relishing the thought.

"Sorry Granny, we've got something else planned this time, after all, today is our parents' wedding day." Applebloom said, causing Granny to drop her frying pan.

"Well it's about bloody time, I've been waiting for this damn day for too long." Granny said, scrambling to reorient the frying pan before the handle caught fire. "So it's time to start training your mother, I'm guessing."

"It'll have to wait until after their wedding night, that's when our brother Big Mac is bred, but onto another subject of importance." Applejack took another vial of potion from between her tits, this time a sickly green. "Our mother has a mighty deadly condition, skely-bones they call it. Nasty condition that'll eat at her muscles and cause pain and death. We... we lost her first and our Pa will die in a later accident with Timberwolves."

Granny noticed that Applejack's tone had changed a little from when she had last met her, from devious, confident and sensual to now containing a note of sombreness and grief. Applebloom too had grown quiet as she mentioned that before the older sister recomposed herself and shook the potion in her hand.

"But this will change that, not only protecting her muscles from her condition but also strengthening them, giving our Master a much better ass to play with." Applejack explained, her thumb rubbing against the glass of the bottle.

"Ah'll make sure she takes her medicine, right after she's learned her lesson." Granny Milf promised, her mind already preparing for a lesson with her new daughter-in-law.

"We're glad to hear it, it's sad that we can't stick around anymore but we'll see you in the present." Applejack explained, a portal opening up behind them. They stepped back through and disappeared, leaving Granny Milf with her new mission.

To begin with, things proceeded as her visions of the future had dictated things to progress, Bright Mac and Pear Butter were married in secret, with both Cup Cake and Burnt Oak witnessing the ceremony whilst Mayor Mare oversaw the ceremony. Granny Milf could not help but be intrigued by Cup Cake or Mayor Mare, she had been instructed to leave those two alone, so that her Master may have the privilege to corrupt them himself later.

As she was doing exactly that, Grand Pear turned up to crash the wedding. Granny Milf had to admit that a secret part of her relished him losing his daughter after all the stress their rivalry had put her family through. After years of undermining her efforts to turn Ponyville into a real whore town with his prudishness and conservatism, it was a real treat to watch his daughter turn her back on all of that and join the Apple Family's ways of sex, sluttiness and servitude to their Master.

Even if she didn't quite know it yet.

They retired back to the barn, and the two newlyweds went straight upstairs into Bright Mac's bedroom, with Granny Milf pretending not to know what they were getting up to. She went to bed early, as she knew her son was a late riser, and when she woke up she found that he indeed hadn't woken up yet, however, she was glad to see her new daughter-in-law had.

Pear Butter's hair was a mess, her face radiated with the soft afterglow of sex, but her eyes were strained with a lack of sleep. She was making herself a cup of coffee, wearing little more than a tank top and some booty shorts, likely only a stopgap in order to wear something more concealing later. At least, she would if Granny Milf didn't have anything to say about it.

"Um... Morning." She said an awkward smile on her face. A short awkward pause took place between them, which caused her to take another sip of her coffee. "So what should I call you? Granny seems a little presumptuous but then again it is your name so..."

"Granny is fine dear." Granny Milf assured her, arms folded with a proud smile on her face. "Welcome to the family."

"Wow, really just like that?" She asked, letting out a breath of relief. "Thought after all the issues between the Pears and the Apples it'd be..."

"Now, don't be mistaken dear, yer still going to have to learn to take part in the Apple Family Traditions, but there ain't no point keeping a grudge." Granny Milf explained whilst she tried to think about the best angle from which to corrupt her.

"Oh, of course, wow. It's glad to see that you're so welcoming, I was worried." She said, mood much improved, before becoming much more solemn. "I wish Dad could have been as understanding as you."

Secretly, Granny Milf was ecstatic to have gotten one over her Pear Family rival, and once she had corrupted Pear Butter fully, she would be eager to rub it in his face, but of course, she didn't mention any of that. "Forget him, he ain't worth it."

This didn't dissuade Pear Butter's sadness so instead Granny Milf took a different tactic. "Hey, yer husband will be working the farm all day today, so why don't I take you out into the town in order to welcome you into our family? Just leave a note for old Bright Mac so he doesn't get too worried."

"You'd do that?"

"Reckon course, I'd love to get to know you better. Love to know all about you."

Author's Note

I forgot to thank everyone last chapter for all the wonderful ideas you gave me last chapter, and if you have any more suggestions for the corruption of Pear Butter (or simply want to reiterate them so I don't have to comb through previous chapters).

On another note, and I feel a little guilty asking, but the artist who I depend on for commissions in this story, Nauth, has been in a bad financial position, and I'd like to both help him out and get more sexy pics for the story. So if you're interested, and only if you're interested, please consider donating to the crowdfunding for commissions.
