After such an arduous morning of tending her flock, er, subjects, Twilight spent much of her lunch break in her favorite pastime. Organizing books! Her new library would never replace the sentimentality of the one she lost in the war against Tirak, but in terms of volume, there was simply no comparison. This was the superior library. And, being such a generous princess, she made it available to all of Ponyville, though not before giving everyone proper lessons in how to care for books.

“Hey, Twi!” Called a somewhat crackly voice.

“Oh. Hello Rainbow.” Twilight quickly descended from the upper shelves and met her friend with a soft nuzzle. “I thought you were busy this morning.”

“I thought I was too.” Rainbow puffed out her chest in pride. “Turns out I underestimated my own abilities. And with your new duty roster, we’ve already set up the weather for all today and most of tomorrow. So I decided to call it early.”

“Rainbow,” Twilight sighed with a mix of exasperation and relief. No matter what, Rainbow was still Rainbow. “I thought AJ was going to have a talk with you about this.”

“Oh she did,” Rainbow said with a guilty grin. “Until I gave my counter argument.” She opened her mouth and flapped her tongue suggestively. “Mare was putty in my hooves.”

“Was she now?” Twilight tapped her hoof impatiently.

“Oh! Sorry.” Rainbow realized her mistake and nodded her head in a soft bow. “Thanks a lot, princess.”

“You are most welcome,” Twilight beamed, glad that Rainbow remembered her manners. Just because they were good friends didn’t exclude the pegasus from basic courtesy.

“But I mean it,” Rainbow insisted. “I know we all owe you for being an alicorn and looking after us and all, but this is personal. If it weren’t for you, me and AJ would’ve never gotten together. We’d still probably be farten around using a bunch of silly competitions just so we’d have an excuse to hang out without looking suspicious.”

“Well…” Twilight blushed with a shrug. “All I really did was tell you two to be honest with yourselves.”

“It’s not just us either.” Rainbow went on. “Mac with Cheerilee and Fluttershy. Spike with Rarity and Sweetie. Come to think of it, thanks to you I don’t think there are more than a couple dozen single ponies left in Ponyville.”

“Oh stop.” Twilight waved a hoof. She was pretending to be humble, but in truth she was very proud of her accomplishments. “I didn’t do that much. I just helped ponies get over a lot of their silly inhibitions. After all,” she straightened up and fanned her wings out in her most regal pose. “It is the duty of we alicorns to ensure that our ponies are well taken care of.”

“Speaking of inhibitions,” Rainbow continued. “Me and AJ have been talking, and we’d really like for Mac to stud for our foals, but he’s not really too keen on it.”

“Our, as in the both of you?” Twilight asked. There was no judgement. She just wanted clarification.

“Yup. AJ’s got a thing for her brother’s super dick and I’d like me some of that too.” The cyan pegasus licked her lips. “You think you could give him one of your special talks?” She asked while using her hooves for air quotes.

Twilight frowned, despite the entertainment value of her friend’s gesture.

“What’s the matter, Twi?”

“This might require more than just a talk,” Twilight said as she galloped off to the library’s restricted section with Rainbow following close behind.

“Why? What’s the matter?”

Twilight stopped at a seemingly unimpressive wall as her horn lit with the black light of alicorn magic. The wall folded in on itself to reveal a hidden room. The princess entered and quickly snatched up one of the books Celestia had leant her on Dominance’s secret history. Seeing as her friend was beginning to grow nervous, Twilight decided to calm her down. “I don’t think it’s serious, but if Big Mac’s still fretting about little things like incest, then that might suggest some sort of flaw in Dominance.”

“Flaw?” Rainbow’s panic was beginning to heighten. Dominance was a closely guarded secret of the crowns. However, as a Councilor of Friendship, Rainbow and the other former Elements were entitled to such knowledge. They were well aware of how Dominance had changed them and all of Ponyville. However, the nature of Dominance helped them to understand why it was a good and necessary thing. They were grateful for the way Twilight had used the spell to improve all their lives. This was why Rainbow was so worried, for a flaw in Dominance could compromise the great life she now enjoyed with AJ. “What kind of flaw?”

“Maybe flaw isn’t the best word,” Twilight said mostly to herself as she scanned through the book. “I might be jumping the gun here. Ah ha!” she proclaimed as she found the section she’d been searching for. “It’s probably just a little gap in the grid. If so, it should be easy to fix.”

“But I thought you changed Dominance so that it wouldn’t have gaps anymore.”

“I thought I did,” Twilight said as she reached for her saddle bag and loaded it with some of the charts she’d drawn of Ponyville’s magical grid and how it related to Dominance. “But it’s okay. If I can figure out what caused the gap, I can make adjustments to the spell to make sure it doesn’t happen again.”

Rainbow made a sound of relief. “That’s a load off my shoulders.”

“Not if we get to Sweet Apple Acres and get the gap closed before lunch,” Twilight said with a suggestive waggle of her eyebrows. Rainbow quickly caught on and soon the pair were racing to the farm.

“And you’re sure you don’t want to mount this?” Twilight asked, pointing at the subject matter.

After being eaten out by her marefriend, AJ had bent over with her rump held high and tail flagging to give all a clear view of her winking pussy. It was this that Twilight was pointing to as AJ spread her butt cheeks apart for extra incentive, letting her brother know that he was more than welcome inside her. And yet the giant of a stallion just stared on with his usual neutrality.

“E’nope,” Mac said flatly.

“And what about this?” Twilight moved down from AJ to Fluttershy, who had also been eaten out, had her tail flagged, and plump rump spread, leaving nothing to the imagination. Her belly also bulged with the foal her virile stallion had planted in her some months ago. “Do you want to mount this?”

“E’yup,” Mac said as his mammoth cock immediately jumped from his sheath and hit the ground with a soft thud. His wife’s supple bottom never failed to arouse him.

“And what about this?” Twilight turned around and flagged her tail up for Big Mac to see her dripping pussy, swaying balls, and unsheathed cock, but did not demean herself by bending over and spreading herself. She’d fucked and been fucked by the red stallion before, so this was nothing new. “Would you like to mount this?”

“E’yup,” he said, this time swallowing to keep from drooling. The other mares giggled at his enthusiasm. Even Granny Smith and Apple Bloom, who had been watching from off to the side, were enthralled by this predicament and Twilight’s efforts to solve it.

Twilight turned back around to face the stallion, her face scrunched in contemplation. Her horn was lit to examine the flow of magic in the area, yet there didn’t seem to be any noticeable gaps or flaws in Dominance. More so, Mac’s behavior was perfectly in line with what had become the new norm around Ponyville, all save for the simple peculiarity of not wanting to fuck his sister. Incest had been just one of many silly taboos that she had thrown out. Granted that this one did have some basis in biology, but modern magic was more than capable of ensuring all foals were born without defects.

“Fluttershy.”

“Yes, Twilight,” the butter pegasus spoke softly.

“You love Big Mac, right?”

“O-of course!” Fluttershy insisted despite her stuttering. “He’s my husband and the father of my foal. I’ve,” she blushed and tried hiding behind her mane. “I’ve also had a crush on him since I first came to Ponyville.”

“You and every other mare and filly in town,” AJ joked.

“But I only got the courage to really talk to him thanks to Dominance,” Fluttershy added. “Thank you for that.”

“Good.” Twilight nodded. “Now, I want you to imagine for a second that you weren’t pregnant and that Big Mac was actually sterile.” She waited for the image to sink in. “You still wanted a foal and someone like… Mr. Cake offered to stud for you. How would you feel about that?”

Fluttershy didn’t take long to consider. “I don’t think I’d mind.” Her tone was as dispassionate as if she were asked to choose between two equally plain pieces of silverware. “I mean, it’d be sad if I couldn’t carry my Biggy Wiggy’s foal,” her words caused the hulk of a stallion to turn away in embarrassment, “but I don’t think that’d really change anything. So long as we’re together, I think it would all be fine.”

Twilight nodded and turned to the stallion. “What about you, Mac? How would you feel if you were infertile and someone like Mr. Cake had to stud for your mares?”

Mac took even less time to answer. “Same.” He shrugged, but discerned from Twilight’s expression that she wanted more. “Ah mean, Ah don’t see nothin’ wrong with that. Mr. Cake’d just be doin’ us a favor, like a good neighbor. Bit more personal, but t’ain’t much different than when we spot each other fer drinks. Wouldn’t change how Ah feel bout mah little Butter Blossom or Cherry Smile.”

Fluttershy blushed at the use of her pet name.

“I see.” Twilight nodded. So far all of this was in line with the changes she’d designed. Ponyville had become a land of openness and free love. One couldn’t simply go around and mount anyone they wanted on the streets. They’d have to ask first and then find a nice secluded spot. Generally the party being asked would accept now that they’ve all been stripped of their old hang-ups. So long as the mare wasn’t in heat, sex was nothing more than a means of bonding between ponies and used to spread the magic of friendship. “But you still don’t want to fuck your sister?”

“E’nope,” he said flatly. “Ah don’t mind doin’ it with Dashie here, but Ah draw the line at mount’n any of mah sisters.”

“Uh, Twi,” Rainbow whispered. “This might sound dumb, but why don’t you just tell him to mount her? Wouldn’t that fix everything?”

“No, Rainbow,” Twilight sighed. Dash wasn’t wrong, but she was missing the point. “I could just tell him what to do, and he’d have to obey, but that’s just a bandage solution. It doesn’t solve the core issue that he has to want it on his own.”

“Sorreh Princess.” Mac shrugged. “Ah know what ya’ll want and I wish Ah could give it ta ya, but Ah just can’t bring mahself ta look at mah family like that.”

“Family?” Twilight considered, repeating the word under her breath until her eyes shined in realization. “That’s it! Mac. You like Mrs. Cake, right?”

“E’yup.”

“She’s a really good friend and neighbor, right?”

“E’yup.”

“And you have no issue with fucking her, her husband, or both at once if you were in the mood. Right?”

“E’yup.”

Twilight’s grin was growing with her excitement, along with her erection. There was a little known element to these kinds of wide area spells and how they could be augmented, not with more magic, but through logic. “You and the other Apples are very close with everyone in Ponyville. In fact, you’re so close it’s almost like you’re family in spirit, don’t you think?”

Mac had to ponder this a moment, but eventually nodded. “S’pose so.”

“In fact, it wasn’t too long ago that Rainbow and I were declared honorary members of the Apple family, right?”

“E’yup.”

“So, since Rainbow is honorary family, and Ponyville is also like you’re extended family, and you’re willing to have fun with all of us, why is AJ any different just because of a little blood?”

As Mac pondered Twilight’s reasoning, the young alicorn could sense the fluctuation of magic around him. Dominance was in Mac’s mind and body, reading and rewriting him all at once to better fit the will of the alicorns, as it was meant to. In time the fluctuation passed and the red stallion looked at his princess with beaming pride.

“It ain’t!” he declared with a bold stomp of his hoof. “Ponyville’s all one big happy family and Ah shouldn’t get mahself hung up over the little things.” The large stallion set his hungry eyes on the orange mare beside his wife. Both rumps were an alluring site, but his sister’s had the added appeal of being something new. They’d both had plenty of lovers since Twilight brought Dominance to their town, but the old taboo of the forbidden fruit lingered in Mac’s brain just enough to add that extra layer of excitement.

“That’s mah brother!” Apple Bloom cheered.

“Way t’ go, sunny. Maybe later ya could help this old bitty feel like a spry young thing again?” Granny offered as she casually hoofed herself.

Mac wasn’t listening though. All of his attention was focused on those firm powerful flanks that only came from a lifetime of honest labor. He was drooling as he walked forward, almost in a daze. Apple Jack, his sister, the filly he’d helped raise, being there for one another during the good times and the bad, was staring at him with a yearning that sent an arrow through his heart. How could he have ever been so foolish for ignoring her need? All titles and honors aside, she was his sister and she deserved the very best he could offer.

AJ gave a muffled moan as her beloved brother pressed his nose against her folds. A shiver ran down her spine as she felt his tongue dart out experimentally. Her pussy was winking around the exploring appendage, trying to gobble it down and pull it in. As her hooves dug into the dirt beneath her, AJ glanced to her side to find Fluttershy smiling sweetly at her. There wasn’t a trace of malice or envy in the butter yellow mare’s eyes, only genuine kindness and joy for her friend finally knowing the pleasure of her beloved husband’s affections.

All mares, and stallions for that matter, had their own unique flavors. Big Mac had had a joyous time learning the truth of this as he sampled and was sampled by virtually every pony in town. Save for the one issue, it had been an open buffet. Mare or stallion, colt or filly, all were treats to be enjoyed. And his sister was no different, tasting of salty sweat around her butt cheeks while her inner juices were more like that of a fresh apple. As much as he loved this, wanting to savor the taste and drink in the smell forever, the twitching between his legs reminded him of more urgent needs.

Mac promptly hopped up onto his sister’s back, resting the full magnitude of his weight upon her relatively smaller form. He knew she could take it. He nuzzled his cheek between her shoulders, savoring the feeling of her breathing against his belly. Using his hooves, he carefully lined himself up and pressed the tip of his flaring shaft against her winking pussy.

AJ whimpered as she felt the first inch of her brother’s cock enter her moist pussy. He was so big, almost as big as Twilight, but that didn’t matter nearly as much as the fact that it belonged to the stallion she’d always secretly crushed on since they were little. She’d told herself that it wasn’t meant to be, but Twilight had finally freed them of such silly notions. And now she could enjoy the full experience of her brother, the biggest stallion in town, gently sinking inch after inch of his mammoth foal maker into her moist marehood.

His shaft burned inside her, as she no doubt burned around him as she craved the sensation of being filled. Each second filled her with greater want as he sank deeper, hollowing her out with his rod. She gave a light moan as she felt him pull out a short ways, only to sink back deeper than before. She knew, as Fluttershy and Cheerilee were fond of describing, how Mac loved taking his time getting his lovers good and ready for a good fucking.

“He’s really gentle when he starts,” Fluttershy commented as she nuzzled AJ’s cheek. The wet shlicking sound of the penetrating dick provided the ambiance. “My Biggy Wiggy knows how big he is, so he always starts out by easing you into his girth. He’s nice like that.” The Pegasus gave her husband a wink, earning a smile in return as he grunted. “But that’s just for starters.”

Big Mac huffed as he felt himself finally hilt inside his sister, his balls touching her inner thighs. “Sis?” he asked.

AJ felt like she was melting around his cock, but managed to peek over her shoulder and answer with the softest of nods.

With his sister’s permission, Big Mac pulled out almost to the tip, only to slam back down with greater force than before.

“Once he gets started,” Fluttershy continued as she savored the look on her friend’s face, listening to the wet smacking sounds of her husband’s thrusting. “He’s like a machine, pounding a mare’s pussy until she feels like gelatin.”

Hearing the normally shy mare use such lewd words was sending AJ over the edge. She couldn’t bring herself to turn her head, but she knew her lover, family, and princess were all watching her get her pussy smashed by her older brother, and it was amazing. She pressed her hooves down on her muzzle to stifle her joyous wailing. She pressed her rump up higher, trying to meet her brother’s powerful thrusts, but she doubted it made a difference compared to his power.

Mac snarled like a beast as he bit down on his sister’s neck, hilting one last time in his sister’s cunt. A flood of cum erupted from his tip into his sister, filling her with its warmth. Her pussy continued to wink around his shaft as she pressed back, wanting to milk him for all she could. His seed was her reward and she wanted every last drop inside her. She whinnied gratefully as her brother just stood there, basking in the afterglow.

After realizing that slopping smacking sounds of sex were still in the air, Fluttershy pointed the siblings over to Rainbow. The cyan mare was bent over with her ass up as Twilight pounded into her. No doubt the princess had become excited from their ‘sibling bonding’ and the ever loyal Rainbow was offering relief. AJ was happy at seeing her wife happy, but also proud of her for doing her duty to service the alicorns. Big Mac had similar thoughts, only he was wondering if it’d be too presumptuous to ask for her blessing after she’d already gone through the trouble of making him realize what he’d been missing out on. In the end, the siblings settled on watching their friend and lover do her duty while their continued to enjoy the feeling of one another’s bodies, a delight that they would partake in for many years to come. a

Author's Note

A fairly routine chapter, all things considered, as Twilight goes through the motions of maintain and strengthening her hold over the town. Everyone’s aware they’ve been brainwashed, but they’re not too put off about it. In fact, most are downright thrilled about how things have changed. However, can Ponyville really be such a paradise?
