[M/F/Futa] For this special Mother’s Day, all Twilight Velvet wants is to receive the “royal treatment” from her kids—the kind involving their massive, throbbing cocks.

Twilight Velvet’s kids have blossomed into pinnacles of sexuality, from Twilight Sparkle’s full, enormous breasts, to Shining Armour’s chiseled, statuesque muscles. For this special Mother’s Day, all Velvet wants is the same “royal treatment” they administer to Princess Celestia—the one involving their huge, throbbing cocks. Fortunately for her, neither of them can resist a MILF with wide, foal-bearing hips, hourglass curves, and perky, luscious boobs.

The Royal Treatment

The clocks had chimed noon by the time they arrived at the house. Of the many things that had changed over the years, Twilight Sparkle’s old home was not among them. The midnight-blue walls, grey carpets, and walnut wooden railings and tables were exactly as she remembered.

“Make yourselves comfortable,” Twilight Velvet said. “I'll get sandwiches.”

Shining Armour shook his head. “It’s Mother’s Day. We should be doing things for you, not the other way around.”

Velvet tutted at him. “Never you mind! Your company's all I need.” With that, she rushed into the kitchen.

Twilight and her brother exchanged glances. “That's Mom for you, I guess,” Twilight said. They left their luggage near the door and made their way into the living room. The purple couch by the coffee table looked smaller. No, Twilight had to remind herself, I've just grown. It was still large enough to accommodate both her and her brother, but only just.

Shining had always been quite tall for a stallion—all six and a half burly feet of him—and Twilight’s ascension to alicornhood had caused her height to rival his. She had still not grown used to being on his eye level… or his occasional glances at her tits, which bounced and jiggled every time she took a step. Considering how Shining had spent most of his adult life protecting—But mostly fucking, Twilight corrected herself—Amazonian alicorn princesses with epic tits, Twilight hoped he would be able to see past her newfound figure.

But her every curve just screamed fertility. In less than two years, her body type had gone from petite to incredibly voluptuous, and she was undeniably one of the sexiest mares in all of Equestria. While her sleeveless yellow t-shirt was modest enough, it still showed off her enormous breasts that were easily double the size of her head. She allowed herself a frown as they lounged on the sofa.

Her brother had quite the figure himself, and Twilight would be lying to herself if she did not find him attractive. But she at least liked to think she never ogled him like that. Maybe because he’s always been like that, and I’m just used to it… whereas I basically became the thing that turns him on overnight. At least he did not know about the other, extra thing she grew—the massive pony-python between her legs. And it needs to stay that way.

“Y'know, Twily, we should do this more often,” Shining said wistfully. “It's relaxing, you know?”

Twilight leaned back and stared at the ceiling. “You can say that again. Not having to worry about anything is great, even if it's just for a day.”

“I love my Flurry Heart,” Shining said, “but she's a real handful. Imagine—me, a dad! It still sounds weird.”

“It sure does.”

“Say, Twily...” She did not like the coy tone that crept into his voice. “You haven't found a special somepony yet, have you?”

“No,” Twilight said perhaps too quickly. Although she was sure she could trust him, she did not dare mention what she had been up to—or who she had been sleeping with.

“Aw. I'd make a great uncle.” After a moment, Shining cleared his throat. “So, you don't have anypony at all? The way you said no—”

“I don't.” Twilight sat upright and looked him in the eye. “There's no way I'd have time for a foal, especially after seeing what Flurry Heart is like.”

“You can say that again,” Shining said with a shake of his head. “I'm surprised you haven't found somepony, especially with the way you look now. Not that you didn't look good before, it's just that—I mean—”

Twilight pressed a finger to his lips. “I know what you mean. I'm... endowed like the other princesses. It's just that I'm so busy, the only guy I'm around is Spike.”

“Isn't he eighteen by now?”

“Nineteen.” Twilight heaved a wistful sigh. It seemed not so long ago that she had hatched him from his egg. “But he's more like my—our—little brother than anything else, remember? That'd just be weird... although I have caught him staring at me on a few too many occasions...”

“Huh.” Shining looked puzzled. “I didn't think dragon girls even had tits, not being mammals and all.”

Twilight backhanded him in the chest. “Shiny!”

“What? I'm just saying, I didn't think he'd be into fillies with big—”

Before things could escalate, a call of, “Who's hungry?” came from the kitchen. A moment later, Velvet entered the dining room with a tray of daisy sandwiches, three cups and saucers, and a piping hot teapot. They spent most of the afternoon sipping Earl Neigh, laughing, and filling each other in on what they had been up to over the past months.

A few hours had passed by the time Velvet stood and said, “I need to fix dinner. You two should get ready.”

“You did bring something nice to wear, right?” Twilight said, giving her brother a scrutinizing look. He wore a blue-and-white striped polo and a pair of navy shorts.

“You mean this isn't ‘nice’?” He held up his hands. “I'm kidding. We'd better get changed.”

Grinning, Twilight shook her head. They retrieved their luggage from the front of the house and made their way up the stairs. Twilight took a right, and found the door to her old room open. It looked like she had never left. Everything was there, from the bed, to the bookcases, to the study desk. The bed was much too small for her now, and she guessed her mother used this as a guest bedroom.

She closed the door and opened her suitcase. Apart from tomorrow's clothes, there was little in there apart from a special dress Rarity had designed for her. Magenta shimmered around her horn, and the door locked with a click. Even if they were family, she did not want either of them walking in while she changed.

Hooking her thumbs into the waistband, Twilight pulled her jean shorts down until they dropped to her hooves. She kicked them off before removing her shirt. With nothing to contain them, her boobs jiggled with her every move. Her dark-purple nipples began to harden, and for a moment, she considered jerking off. Relieving herself always felt good, and it cleared her mind—especially on occasions where she had no time to milk her cock at least once in the morning, such as today. But almost as quickly as the notion came, she thought better of it. Knowing full-well how messy her orgasms were, Twilight realized there was no way for her ensure there would be no evidence.

After indulging herself with a couple squeezes of her sensitive boobs, she gave her white panties an affectionate pat. They were tight to the point of being uncomfortable, but the special thrice-reinforced material pressed her horsecock against her crotch so well, there was only a barely noticeable bump. Twilight turned her attention to her dress. With a quick whisk of magic, she straightened out the wrinkles and slipped into the garment.

She dug around in the suitcase and retrieved the lavender sash that completed her getup. Standing in front of the mirror beside the closet, she tied the sash around her narrow waist, letting the knot rest on her left hip as Rarity had instructed her. The dress was simple enough; the silken fabric was a mixture of purples and blues, giving it the appearance of a clear, darkening sky. It was a long dress, with its hem riding several inches below the knee.

The only immodest aspect of it was what Twilight referred to as the boob window. It was in the shape of her cutie mark, and it had an inch-wide border of glossy magenta thread. She remembered arguing with Rarity about it.

“It completes the look, darling,” Rarity had said. “It's not risque, it's fashionable.” Despite Twilight's insistence that it drew way too much attention to her ample cleavage, Rarity had countered, “Dear, nothing can draw attention away from your chest. You may as well let them breathe, and look good while doing it.”

And so, that brought Twilight to what she now wore. “You could've made it a little smaller,” she said, frowning. If the window were another half-inch wider, her nipples would be at constant risk of escaping the dress's confines. After she took a moment to brush her hair and tail, Twilight headed out the door.

Shining Armour leaned against the wall opposite the door. “Hey, lookin' good, Twily!” He wore his old crimson-and-gold Captain of the Royal Guard dress uniform, complete with its polished silver lapel pins and cufflinks of office.

“You, too, BBBFF,” Twilight said. She led the way downstairs. It was not long before the aromas of mild spices and steamed vegetables reached her snout. “Oh, that smells so good!”

When they took their seats at the dinner table, Velvet stepped into the dining room and clapped her hands. “Now don't you look handsome, Shining. And Twilight, you really do look like a princess.”

Twilight was too surprised to reply. Velvet wore a royal-blue dress that glittered in the light like a cascade of sapphires. After several long moments, Twilight finally managed, “You look good, too, Mom...” What had taken her aback was how low-cut the dress was. Velvet's full, E-cup breasts barely stayed in the top, and the bottom showed more thigh than it hid.

The pink tinges on Velvet's cheeks showed she had guessed some of Twilight's thoughts. “Oh, this? I used to wear this on date nights with your father. It was all I could slip into on short notice.”

“But you knew we were coming—” Twilight began, but Velvet had already ducked back into the kitchen.

Shining let out a low whistle. “She, uh, picked an interesting dress.”

“Yeah, interesting.” Twilight had never thought of her mom as curvy, but the dress left nothing to the imagination. If there was any truth to Velvet's words, it was that she had worn the dress before marrying Night Light. Her breasts, which had grown at least a cup size during motherhood, never shrank back to their original size, constantly threatened to spill out of the dress's too-small top.

The awkward silence that followed lasted until Velvet reentered the dining room with three dinner plates and a bottle of sherry in her magic. Each plate bore a medley of steamed, lightly seasoned vegetables, including broccoli, baby carrots, beets, squash, Brussels sprouts, and snow peas, as well as mushrooms and sweet potatoes. Shining Armour's plate also had—

“All right, corn dogs!”

Velvet gave him a sweet smile. “They always were your favourite.”

Twilight chuckled. No matter how big, tough, or important Shining Armour became, there were times where he would act no different from when he was a colt. The corn dogs even had the same little mustard happy faces squirted on them. They began eating once Velvet had uncorked the sherry and poured three glasses. The food tasted every bit as delicious as Twilight remembered, but drinking sherry with it felt odd; during the countless times she had eaten this home cooked meal as a filly, she had always washed it down with water.

While they ate, her gaze often flicked to her mother's dress. It showed that Velvet had taken great care of herself in her middle age, maintaining her physique from her mid-twenties, and looking no older than thirty.

“Whoops!” On her way back to the kitchen to fetch another bottle of sherry, Velvet dropped the empty one. Her tail swished to the side as she stooped to pick it up.

“Wow, Mom has a nice ass,” Shining muttered after Velvet disappeared into the kitchen.

“Shiny!” Twilight hissed.

Shining shrugged. “What? She does.”

“She’s our mom.” Why didn’t she use magic to pick the bottle up? Perhaps it was her overactive hormones talking, but Twilight could not help but appreciate her mother’s body now that she had decided to flaunt it. As Velvet returned to the table, Twilight could not help but steal a glance at her perky breasts, which gave a nice little bounce with each step she took.

Now that she was paying more attention, Twilight began to notice a few things about Velvet as they ate. She leaned forward more often than was necessary, giving Twilight and Shining unobstructed looks at her full, fuckable cleavage. On several occasions, Velvet took long, exaggerated stretches, which ended with her placing her hands on her wide, curvy hips and pushing her chest out.

Twilight found herself exchanging awkward, confused glances with her brother throughout dinner. At least the food was tasty enough. More and more, her mind began to blur the line between Velvet and somepony like Rarity. No, Twilight told herself, there’s a difference between your own mother and a friend with benefits. Her legs shifted as she felt a familiar stirring within her loins.

She knew it all too well. It was what she had always felt around Princess Celestia, and now Rarity and Princess Luna. Those three mares had several things in common with one another: They had curvy bodies, fuckable, spankable asses, shapely thighs, wide hips, tits that felt incredible in her face, and an insatiable hunger for Twilight’s massive futa horsecock. Velvet certainly shared all of those features, save the last, except her body language told Twilight otherwise. She did not need to look at Shining Armour to know he had to be thinking similar thoughts—especially since she was well-acquainted with his taste in mares.

As they were taking their last few bites, Velvet said, “Actually, there is one special Mother's Day gift I'd like from you two.”

“What is it?” Shining asked. “We'll do anything.”

“There's only a few hours left in the day,” Twilight said. “I wish you'd said something sooner.”

Velvet regarded them for a moment. “It's nothing like that—don't worry. I want...” She bit her lower lip. “I want to be treated like a princess.”

“You're already like a princess to us, Mom,” Shining said.

Twilight nodded. “I know you cooked dinner, but you should at least allow us—well, me—to make you breakfast in bed tomorrow. Nothing says ‘princess’ like breakfast in bed!”

“How about dessert as well?” Velvet said. She stood and motioned for them to do the same.

“Mom?” Shining said.

Twilight scratched her head. “Dessert in bed?”

Velvet flashed a grin that Twilight knew all too well, but only for a heartbeat. It had come and gone so quickly, Twilight was unsure if it was just her mind deceiving her. Velvet slipped between them and took them by the hands. “You might say that. There’s something very… specific that I want from you two.”

“But—”

“Shiny, am I a princess or not?”

Shining heaved a sigh. “All right… Princess Mom.”

“That’s better.” Velvet giggled and tugged on their arms, leading them up the stairs. Twilight could not help but noticed Velvet’s ass swaying a great deal more than usual as she sauntered up the stairs—and because she was a couple steps ahead, it was right in her and Shining’s faces.

In her younger days, Twilight had seldom visited her parents’ bedroom, like it was a different world where she did not belong. Despite this, she remembered it perfectly as she once again laid eyes on it.

While it was similar to the rest of the house in design, it also boasted a walk-in closet, en-suite bathroom, and soft woollen carpet. Nightstands stood on either side of the queen-sized bed with wrinkle-free beige sheets. When they were all inside, Velvet magicked the door shut behind them.

“So… what’s the, uh, specific thing you wanted?” Twilight asked.

Velvet had released them from her grasp, and now wrung her hands as she stared at them almost hungrily. “There is something, yes, something only the two of you can provide.”

“You mentioned dessert, but I don’t see anything,” Shining said.

Velvet bit her lip and looked between her offspring almost nervously. “I’m looking right at it.”

“Huh?” Twilight and Shining said in unison.

Velvet closed her eyes and took a deep breath before opening them again. “I know what you two do with princesses—your ‘royal duties,’ Shiny. Before you tied the knot, you made sure Her Highness was... satisfied. Princess Luna, too, when she returned.” A stunned silence followed. “Both of you, in Princess Celestia's bed—pleasuring her. I want to be your princess tonight. I want you to do to me what you've done to her.”

Twilight buried her face in her hands. She felt herself going redder and redder.

“Mom...” Shining said. “How did you...”

“Princess Celestia told me,” Velvet said. “She stopped by for tea a few months ago and thanked me for having offspring who really knew how to show a mare a good time.”

“She told you?” Shining sounded just as aghast as Twilight felt. “Wait. Both of us?”

Twilight could feel the heat on her cheeks. She had never thought of Celestia being the type to kiss and tell. Or, in this case, fuck and brag—to Twilight's own mother, no less.

“You always had a thing for her, didn't you?” Shining said, clapping Twilight on the back.

“The Princess made no small point of telling me how wonderful you two were,” Velvet said in silky tones. “Ever since then, I knew I had to experience it for myself, even for just one night.”

“That what all this was about?” Twilight’s voice sounded hollow. “The dinner, Dad’s ‘business trip,’ your dress—all for this?”

Velvet nodded. “The way Princess Celestia described it. I asked her how she managed to keep things exciting, especially since she’s immortal.”

“So, you assumed she slept around?” Shining folded his arms, but did not sound offended.

“Well, I didn’t know what to think,” Velvet said. “At least, not until she started spilling the beans. She made no small point of saying just how wonderful you two especially were. Coming from somepony with her millennia of experience, that’s quite the vouch. You can imagine that she’s seen quite a lot, but she said both of you could make her lose herself.”

The news made Twilight feel dizzy. Her affairs with the Royal Sisters was supposed to be a secret. “So… Celestia implied that you should seduce us—your children?”

Velvet shook her head. “She didn’t imply. She suggested it.” She held up her hands at Twilight and Shining’s gasps. “I was skeptical at first, too. Believe me. I mean, you’re my foals! How could I possibly consider having sex with you? But then, she told me she’d thought the same thing about Princess Luna. Once, during a cold Hearth’s Warming Eve, all the fires in the castle had gone out, and they’d cuddled for warmth. One thing led to another, and… well… Celestia said it was some of the best sex of her life. She didn’t need to point how you two are some of the sexiest ponies in all of Equestria, or how good you were in bed.”

“But... you're our mom,” Shining said, sounding no less confused. “We can't have sex with you.”

“You don't think I'm good-looking?”

“Mom...”

“Is it because my breasts aren't bigger than my head?” Velvet hefted her tits, which were large enough to spill out of her hands. “They're not huge, but I'm not exactly flat.”

“Mom...”

“I know you're used to being with mares much prettier than me, but you know what they say about cougars...”

“Mom!” Shining barked. “It's none of that. You look very good for... I don't know how old you are. It's that you're my mom.”

“You're not a colt anymore,” Velvet said. “Tonight, we can just be consenting ponies enjoying one another.”

Twilight finally found her voice. “Princess Celestia told you... everything?”

“Oh, yes,” Velvet said. “You more than filled your brother's horseshoes. I'm so proud of you, Twilight. It's so important to follow your dreams... which is why I'm following one of mine. Right here, right now.”

“You don't think it's weird?” Twilight looked at her mother between the gaps in her fingers.

“Not at all!” Velvet took one of Twilight's hands in hers. “I especially want to feel what you make Princess Celestia feel.”

“Mom,” Shining said, “this whole thing is because your sex life with Dad's gotten stale?”

Velvet looked at him for several seconds before sighing. “Well, that's not entirely why. Most of it is what I told both of you. There's also... just look at you. Anypony with any sort of active sex drive would kill for a night with either of you. You're both the pinnacles of the mare and stallion forms. I don’t care if we’re related. You’re both just so… oh, I get wet just thinking about it. I can’t help myself.”

Everything was moving so fast, Twilight felt dizzy. She did begin to understand her mother's point. After all, she knew exactly what her mother was talking about when it came to Celestia and Luna enjoying one another. Could incest really be so wrong if Equestria's rulers practiced it? “Mom, you're sure you're okay with my—”

“Yes, I am, Twilight.” Velvet stalked around the table until she stood between Twilight and her brother. “Look, I know I'm not Princess Celestia, or Princess Cadance. I don't wear a crown that gives me power over an entire kingdom, and I don't have eternal youth that gives me a body that won't quit. Both of you have grown up into pony royalty. You're incredibly special, not just to me, but to the common public. But tonight, I'd feel even more special than that, if only...”

Shining shifted in his seat. “I dunno, Mom. I'm married.”

“So am I.”

“If Cadance found out...”

Velvet slung an arm around each of them. “She won't need to. She’s in on this, too.”

Shining opened his mouth and closed it several times.

Despite being larger than her mother, Twilight squirmed. Is the whole of Equestria bent on getting us to fuck? The sensible part of her said this was wrong, that she should not even be considering it. But it had been a while since her big, thick cock had been inside anything other than her own mouth, and Velvet was undeniably a total MILF. And ever since she had first been with Princess Celestia, she had always wondered what her brother was like in bed.

There was something about the way Celestia had described her brother and just how good he was at satisfying her. Even on the nights where Twilight made her scream in ecstasy, she staunchly claimed that Shining was just different, and both her and her brother were arguably the best fucks she had ever had. Tonight would be a rare opportunity to see him in action. Oh, Twilight realized, suddenly understanding Velvet on a much more profound level. “Hey, BBBFF?”

“Yeah, Twily?”

“We can be responsible, right?” Twilight said hesitantly. “It's not just us and Mom, it's, well, us. We'll need to be like Celestia and Luna when they...”

“Twily? You're seriously—?”

Velvet kissed Twilight on the cheek. “That's my Twilight! I knew I could count on you.”

“Listen, Shiny,” Twilight said. “We both have firsthoof experience with the, uh, precedent set at the highest level for this sort of thing. And… I just can’t stand it anymore. Both of you are just so hot, like somepony cast the ‘Want It, Need It’ spell on you two.”

Shining heaved a relieved sigh. “I was gonna say the same thing, but I’ve been trying to fight it.”

“We didn't have issues with the Royal Sisters, because we aren't related to them by blood,” Twilight continued, “but we still participated. This isn't that different. Mom's given us the world, and all she asks for in return is one special night. Remember, when Celestia and Luna do that, they’re two of the sexiest mares in Equestria enjoying each other’s bodies. I don’t see why this has to be any different.”

“I...” Shining shifted on his hooves for nearly a minute. “All right. Fine. I still don’t know what’s come over me, though. Don’t get me wrong, but I get plenty of sex goddess T and A, so as hot as you two are, it’s not like I don’t have an all you can eat tight pussy buffet in the Crystal Empire—or Canterlot, when the sisters are up for a bit of fun.”

An impish grin spread across Velvet’s muzzle. “Oh, that would be the sherry. Remember how I said your wife was in on this little gift? Well…”

Twilight’s jaw fell open. The wine! Of course… “She didn’t!”

“She did,” Velvet said. “The spell won’t last for too long, but she told me it’d be enough to get the juices flowing.”

“I guess this is my daily reminder that I'm Cadance's husband. It's like it's that mare's job to come up with new ways to have sex, or something,” Shining said with a shake of his head. “Is it that unbelievable to say this won't be the weirdest thing I've done? There were some nights when the royalty got really, really restless, and put the Royal Guard up to some crazy shit. Then, there was that time I was unknowingly fucking a bug queen.”

Velvet wrapped her arms around Shining Armour and pulled him close until their snouts touched. “Mmm… and now, tonight, you’re mine.” Her eyes closed, and her lips met his. After only a couple of smooches, she tilted her head and leaned into him. Twilight felt her mouth fall open as she saw her mother foregoing any form of pretense and skipping straight to giving him plenty of tongue.

Shining stood motionless as Velvet kissed with him. As if he needed guidance, she took his wrists and moved his arms until his hands rested on her supple, round ass. Her nimble hands moved quickly, undoing the buttons on his uniform from top to bottom. She did not stop kissing him until she had finished with his shirt.

He looked down at her. His hands had not moved from her ass. “Mom, are you really sure about this? Once you get me going, I won't be able to stop.”

Velvet traced a finger down the gap in Shining's shirt. “That's what I'm hoping for. It's been so long since I've been properly fucked.”

The vulgarity coming from her own mother took Twilight aback. There were many things she never expected to hear in her lifetime, and this was one of them. She was so preoccupied that she did not notice Velvet slip from between Shining Armour's hands and dart in front of her. It was not until she felt a pair of small hands groping her expansive breasts that she realized what was happening.

“Goodness, Twilight, you're not wearing a bra.” Amazement hushed Velvet's tones.

Shining Armour let out a whistle. “Damn, I guess she really is a princess.”

A shudder went through Twilight. It felt good to have somepony touch her boobs. “Cadance doesn't need a bra, either?”

“If there's one thing you alicorn fillies have in common, it's that you've got great titties,” Shining said. He pulled his unbuttoned uniform off and tossed it in the corner. Well-defined muscles rippled along his torso and arms. They lacked the ridiculous size of a bodybuilder like Schwarzeneigher, but they looked rock-hard all the same.

Maybe it was what she had heard from Celestia, maybe it was her pent-up feelings, or maybe it was her mother groping her breasts—or all three—but Twilight could not help but stare at him as he stood and watched. She had never been with a stallion before, and her big brother was the pinnacle of male fitness. While she knew he would be fucking Twilight Velvet, a threesome was still a threesome. The thought of it made her nipples hard.

Velvet must have noticed, because she said, “Mmm, come closer,” and the moment Twilight leaned forward, she began snogging her.

Closing her eyes, Twilight kissed back. Her and Velvet's tongues played between their mouths, and Twilight shivered. More and more, the thought of getting it on with her own mother grew appealing. While Velvet kept giving her breasts the attention they demanded, Twilight's hands explored her hourglass curves.

Years of care had kept Velvet's waist slim and narrow, but she retained her wide, generous, foal-bearing hips. Twilight grabbed her by the ass and pulled her closer. She began groping it and quickly realized it was bubbly, firm, and oh so fuckable. Most stallions would kill for a chance to be with a mare like her, and Twilight could feel her hormones beginning to take over.

The sound of a zipper being drawn cut into her thoughts. She opened her eyes, but did not stop kissing Velvet. Shining Armour stood right behind their mother with his hands resting on the small of her back. He stared at them kissing, and Twilight winked at him before closing her eyes and deepening their kiss as far as their locked muzzles would allow.

A soft moan came from Velvet when Shining's large hands joined Twilight's on her ass. Velvet's head snapped back. Panting, she said, “Oh, it's getting so hot in here.” It took her several deep breaths to regain herself. “Mmm, Twilight, I've never been kissed like that before.”

“I'm not too bad myself.”

Velvet spun around. “You didn't kiss me back. It looks like Twilight wins the gold star for kissing.”

“Mom,” Twilight said, “the Sibling Supreme ended when Shining Armour helped tighten Canterlot's defences, remember?”

“That doesn't mean we can't make tonight a little more interesting—right, Shiny?”

“Yeah, well, I—”

“Maybe this will help?” In one tug, Velvet pulled her tight dress off, and it lay pooled around her hooves. She wore nothing but a salmon-pink thong. “So, what do you think? I know it's not as much as you're used to...”

Shining looked her up and down. “Damn, Mom, I knew you had an incredible body, but I didn't realize you were this hot.”

Twilight took a step forward and stood beside her brother. Velvet's tits were full and perky with hard nipples that were a few shades of grey darker than her skin. The sight of her made excitement flutter in Twilight's chest. There was a wet spot on Velvet's panties. She looked just as eager to be stuffed full of cock as Twilight was to bury herself inside her. From what she had heard from Celestia and Luna, her brother was packing quite a lot between his legs. She was not sure how Velvet's petite, tight little body would handle it all.

Velvet traced her hands along Shining's muscular body. “Are you ready to kiss me properly now, big boy?” Without waiting for him to reply, she pressed herself against him and kissed him. Her hands explored his back and ass, and her arms flexed as she pulled herself more tightly into him.

This time, Shining Armour did not hesitate. He kissed her back, running his hands along her curves slowly, caressing as he went. The size difference between them made him lean over her, and he used it to press downward as they kissed. Immediately, Twilight felt a twinge in her crotch. Her cock began to harden, but the special panties she wore kept it in check. She wanted to step in and grope Velvet, but the way Shining's powerful arms and hands moved kept her at bay.

Where Twilight leaned more toward the tender side of things when she was in bed with a mare, her brother, while capable of being gentle, was the opposite. The size of his arms and torso made it much easier for him to be dominant and in control even though he was of similar stature to Twilight. His fingers left marks from how hard he squeezed Velvet's ass—a promise of the good, hard fucking soon to come.

Twilight stood back and bit her lip as she watched them make out. It was not long before Velvet's hands started to fumble with his pants. Twilight felt her nethers grow hot as Velvet unclasped Shining's belt. Shining stepped back, breaking their kiss, and grabbed Velvet's tits, which were just big enough to spill over his large hands. She pulled the pants of his dress uniform down.

“Shiny, what in Equestria are those?” Twilight said.

He wore rose-red boxers covered with shocking pink hearts. “My underwear.”

“Aren't those kind of—”

“You'd better not say ‘gay,’” Shining said. “Cadance got them for me. She thinks they're sexy.”

Twilight rolled her eyes. “I know you like mares, but still...”

Shining had not stopped groping Velvet's boobs. “Look, just because these boxers look like something you'd buy at Ram Ranch doesn't mean I'm into eighteen naked cowponies. There's nothing wrong with being into that stuff, but that ain't me; it's hard to be straighter than I am.”

“Yes, BBBFF, I'm sure Cadance thinks you look cute in them.”

Magic shimmered around Velvet's horn. She picked up her hooves and whisked her dress from the floor. Her aura carefully folded it before moving it onto a nightstand. “She likes seeing you in this before you make her feel like a princess, doesn't she?” Velvet said. “Do you take them off, or does she take them off? Does she take them off like this?”

Velvet planted several kisses on Shining's chest, working her way down his belly. She did not touch him with her hands, and she slowly bent her knees. When she reached the waistband, she grabbed it with her teeth. After holding it for a moment, she squatted as low as she could go, yanking the boxers down Shining's legs.

His horsecock sprang free. Half-hard, the off-white shaft mottled with dark-grey splotches was about eight inches long and as thick as a mare's wrist. The boxers fell from Velvet's mouth as it hung open. She stared at the cock that loomed over her head. Twilight admired it, too. No veins were showing yet, which meant it would grow a lot bigger.

But Shining Armour looked at Twilight. “I hope you're not just planning to stand there and watch.” He hefted Twilight's tits and stuck his face into the dress's boob window, kissing her cleavage. “Mmm, Twily, sister or not, you have no idea how long I’ve wanted to do this.”

Twilight laughed. His muzzle tickled. “Let me guess, about a year and a half? That’s how long it’s been since I’ve outgrown a G-cup. You haven't gotten bored of big boobs, huh?”

“Not in your life.” Her cleavage muffled Shining's voice. “Mom, help me with this dress!”

“But you aren't doing anything,” Velvet said. Despite her protests, she walked behind Twilight, her tits giving a little bounce with each step.

Together with Velvet, Twilight pulled her long dress up. Removing it was difficult, since Shining kept his face in her cleavage and his hands on her breasts. It was not until Twilight pushed on his shoulders that he gave her enough room to pull her dress over her head. She let it drop to the floor and grinned as both Velvet and Shining gawked at her immense, gravity-defying bust.

“You really have grown,” said an awestruck Velvet.

“Now this is what I call a nice rack.” Shining's cock had grown a couple of inches. “Cadance was right to be jealous. Even having Flurry Heart wasn't enough.”

“She ascended into an alicorn, too, didn't she?” Twilight said, suddenly wondering if Cadance had also grown a dick from her transformation.

Shining grabbed one of Twilight's breasts. Despite being the size of spades, even both his hands at once were not enough to clutch it all. “Yeah, but she wasn't an adult like you when it happened. Not that she isn't royalty with huge... tracts of land, or anything.”

While he was talking, Velvet grabbed Twilight's other breast and began to grope it. “My goodness, Twilight, you could feed all of Ponyville with these things.”

Pleasure rippled through Twilight as two pairs of hands serviced her tits. Her hooves shifted as Velvet and Shining began to share a sloppy kiss while they groped and squeezed her boobs. “Ooh, that's so good,” she said. Her cock grew more and more uncomfortable in its confinement. These two definitely knew how to get a mare worked up.

She did not know how long it had been before she could not take it anymore. Her hands trembled when she reached for her panties. She said, “Are you two ready?” which brought an end to their kissing.

Velvet turned around and hooked her thumbs in her thong. She bent over, pulling them down as she went. Her tail lifted, presenting Twilight and Shining her already-wet pussy. It looked tight. “I'm more than ready.” Velvet turned to face them once again and tossed her thong over her shoulder. It landed on top of her dress on the nightstand.

“Okay.” Twilight took a deep breath. “Shiny, I hope you won't be too alarmed.”

Shining scratched his head. “Huh? It's not like you've got anything I haven't seen before.”

Forcing a smile, Twilight pulled her panties down. Suddenly free, her horsecock flopped out, hanging halfway down her thighs. Both Shining and Velvet stared at it with wide, shocked eyes. “Mom? What's the matter? Didn't Princess Celestia—”

“She didn't mention that,” Velvet said, her voice little more than a whisper.

Immediately, Twilight went beet-red. “It's just that—I thought that—”

“That... explains quite a lot,” Shining said. “The Royal Guard don't call her ‘Size-Queen Celestia’ for nothing.”

“I think it's why my body grew like it did.” Still overcome with embarrassment, Twilight made a point of avoiding her mother's face. “Somehow, the spell that turned me into an alicorn gave me this. Princess Celestia thinks that because being a futa gives you such an overactive sex drive, it manifests itself in other ways.”

“Oh, Twilight.” Velvet did not sound upset.

“Mom?” The broad smile on Velvet's face made Twilight do a double take.

“I didn't think I'd be getting two cocks tonight. Both of you are already bigger than anypony I’ve been with, and you aren’t even hard yet!”

The nerves Twilight felt calmed almost immediately. “Sorry I startled you. It's just that when Princess Celestia told you about me, I thought she said everything. I try to hide this from other ponies because, well, it's not normal, and not every creature is open-minded. One time, when I was at Griffonstone with Pinkie Pie, we were at a bar after a diplomatic mission. One griffon was drunkenly screaming about how wrong it was for there ‘to be a cock where a cock should not be.’ He kept ranting about it, and at some point he even claimed to be a linguist, which was surprising considering the amount of swearing he was doing.”

“Doesn't sound like a very cunning linguist to me,” Velvet said.

“You know what?” Shining said. “Fuck creatures like that. Seriously. Fuck 'em. Not in the way we're about to fuck. You know what I mean. I've heard of mares like you, Twily, but haven't actually seen one before. If what they say about futas is true, then I think this'll be quite the royal treatment for our princess here.”

“Oh?” Twilight said coyly. “And what do they say about futas?”

Shining lifted Twilight's breasts to his face and gently kissed them. “Well... that they're quite well-endowed.”

“Yes, and?”

“They've got a sex drive that won't quit.” Shining took a nipple in his mouth and sucked on it.

“Well, not to—oh! Shiny, did you grab my cock?”

Shining squeezed Twilight's breasts with both his hands, sending a ripple of pleasure through her. “Did you grab mine?”

Twilight shook her head. They looked down. Velvet, on her knees, had a hand on each of their cocks. Neither of them were hard, but even still, her middle finger could not meet her thumb round the shaft. “Somepony's eager.”

“How could I not be?” Velvet said. “These things are the size of my forearms.”

Shining took a seat on the bed. “I know how to change that pretty quick. Between us, there's two great pairs of tits, as well as two cocks needing attention...”

Twilight and Velvet exchanged glances. “What do you say, Mom? I do him, you do me.”

“I hope I've got enough to work with.” Velvet eyed the dark-purple horse meat in her hand.

“I think you'll be fine. Don't sell yourself short.” Twilight gave her mother's boobs an affectionate squeeze before she sat down next to her brother. She turned her upper body and sandwiched his cock between her massive tits. “I hope you're ready, BBBFF.”

Shining leaned back and ran a hand through Twilight's hair. “I'm always ready for a tit-job.”

Still on her knees, Velvet took her own ample breasts and squished them against Twilight's shaft, enveloping it in her cleavage. Her tits were just large enough to encircle the girthy filly-cock. “Twilight, I've been wondering... are you able to cum with this thing?”

The breasts around her cock were smaller than what she was used to, but she felt her body respond to the sensation all the same. “A little.”

“But you don't have—”

“Trust me,” Twilight said. “Just because I only have mare-parts down there doesn't mean I can't get off.”

Velvet ran her mouth and tongue up and down Twilight's cock. When she reached its peak, she took the head into her mouth with a little difficulty and began to suck. The shivers of pleasure that ran through Twilight's body made her squeeze her tits against her brother's cock harder. Both she and Velvet began to stroke their partners' horsecocks with their tits.

Slowly, Twilight felt herself begin to harden and thicken. Velvet's mouth was incredible on her cock. Her own tits were so big, it took a couple minutes of stroking before the head of Shining's member emerged from her cleavage. She opened her mouth wide and took in several inches, slurping and sucking as it stiffened. Despite the awkward angle, she managed to bend until Shining's cock hit the back of her throat and her face was buried in her tits.

The pair of strong hands on her head told her she was doing a good job as she continued to service the huge mottled stallion cock. Drops of precum leaked into her throat, which she gulped down eagerly. It had a strong, bitter taste to it that her own pre lacked. All the while, her own cock continued to grow. But as she fell into a steady rhythm, a new sensation made her whole lower body quiver.

Twilight did not need to open her eyes to know that Velvet had buried her muzzle deep into her pussy and started to lick, every lap of her tongue sending tingles of pleasure through her nethers. Her legs crossed over Velvet's back and pulled her in. Meanwhile, she did not stop giving her brother attention with her boobs and mouth. She would have gasped if her mouth were not full of horsecock. As Velvet licked at her pussy, she rapidly stroked Twilight's shaft, now slick with saliva and precum.

Shining jerked his hips and tightened his grip on Twilight's head, forcing her to bob on his cock in time with his movements. The head filled most of Twilight's mouth, giving her little room to breathe. She could feel the veins with her tongue as the flesh grew taut. Drool that escaped her lips made it easier for her to slide her tits up and down his impressive length. From here, she could not see how big he was, but she guessed he was over a foot long, around twice what the average stallion packed.

Pressure built in Twilight's nethers. For never have given a mare head before—to the best of Twilight's knowledge—Velvet sure knew how to please a pussy. Her tongue probed deep, hitting most of Twilight's nerve endings. Twilight's legs shook, encouraging Velvet to keep going. Soon, it became too much.

Twilight stopped giving her brother head and pinched her nipples hard as a female orgasm hit her. She ground her pussy into Velvet's muzzle as she came and waves of pleasure rocked her body. Shining must have realized what was happening, because he relaxed his grip on her head, allowing her to pull her mouth from his cock and take several gulps of air. She leaned back, her chest heaving, as she recovered from her orgasm. “Oh... that was so good.”

“Dear Celestia,” Velvet said, her voice awestruck. She stood, her muzzle damp with Twilight's filly fluid, and stared.

Twilight sat up to see what she was looking at: her and Shining's cocks. Although she could not tell for sure, Shining looked to be nearly fifteen inches, while her cock stood at seventeen. She was hard, but not completely; the veins that corded along Shining's shaft were not yet visible on hers. While her horsecock was perfectly straight, Shining's had a slight but noticeable curve to it.

Shining Armour looked at the ceiling and let out a low whistle. “Are you sure you've never been with a stallion before? You give some wicked head—and you know how to use your tits just right.”

“I practice on myself every morning,” Twilight said.

“Huh?” Shining looked down. His eyes bulged when they saw her cock. “Damn, Twily, you're huge!”

A giggle escaped from Twilight's mouth. “Looks like I win the gold star for cock size.”

Shining gaped at her. “I heard futas were hung, but not that big. Just... wow. Here I thought you'd be ten, maybe twelve inches tops.”

“At first, I was.” Twilight slid a hand down the length of her shaft. “But, as the months went by, it kept growing. It hasn't completely stopped yet, either.”

Shining looked at his own stallionhood, which was impressive in its own right. “I guess big cocks just run in the family, huh?”

“Oh, no, they don't.” Envy dripped from Velvet's every syllable.

It was all Twilight could do not to laugh. Oh, poor Dad... “At least we'll help make up for it tonight.”

“Well, I'm big enough to satisfy any princess,” Shining said. “Heck, one night, a few slutty, uh, ‘fans’ snuck into the Royal Guard barracks. None of those poor mares could fit the whole thing in. Besides, you're my sister, and a big titty futa princess. I guess it makes sense that you've got a huge ‘rod of friendship.’”

“This—you two—are so much more than I could've hoped for,” Velvet said, running a hand along each of the cocks before her. She climbed up on the bed, resting on her knees between her offspring. “I know I don't have much to work with, but—”

“Easy gold star for big bro,” Shining said, cupping one of Velvet's breasts. “I've had big tits in my face most of my life.”

Twilight stroked Velvet's other breast. “And I have big tits.”

But Shining did not retort. He had taken Velvet's nipple in his mouth and began to suckle while groping her breast. She felt one of Velvet's hands on her head as she licked at her mother's other nipple. Paying no attention to what Shining was doing, Twilight licked and gently nibbled. With her free hands, she caressed her mother's smooth curves, gliding down her body until one hand reached her ass and the other her pussy.

Velvet shuddered in her clutch as she kept working her mouth while groping her ass and teasing her lower lips with her index finger. Already slick with juices, Velvet's pussy welcomed Twilight's fingertip. Twilight nibbled and sucked gradually harder as she slid no more than an inch of her finger inside Velvet's tight marehood. Velvet's breast was firm and supple against Twilight's face as she pressed into it, her tongue rolling over every bump, wrinkle, and groove of the erect nipple in her mouth.

Velvet began grinding against Twilight's finger. With almost agonizing slowness, Twilight slipped more and more of the digit inside her mother's pussy, which clamped and quivered against its touch. As low moans escaped Velvet's muzzle, Twilight added her middle finger to the mix diddling Velvet with both. She could feel her mother nearing orgasm, and she withdrew her fingers until only their tips remained inside.

It was not until Velvet began to relax did she re-insert her fingers all the way to the knuckles. Again, she brought her mother to the edge, all the while sucking, nibbling, and occasionally biting her nipple, and once more, she let up with her finger play. It was not until the third or fourth time that Velvet edged did Twilight allow her to finish. She vigorously rubbed Velvet's clit with her thumb, and right as her body gave a hard shudder, Twilight pulled her right hand back and spanked her.

Velvet yelled with pleasure and came hard, her pussy trapping Twilight's fingers as she ground against her hand. She moaned loudly as she rode out her orgasm. “Oh—oh... that was so good!” Velvet staggered off the bed, landing on her ass and panting heavily. “This one definitely—definitely goes to Twilight.”

Shining scratched his head. “Huh?”

Grinning, Twilight held up her sopping fingers. Velvet stood and groped her own breasts. “Mmm, I think Shiny did a bit better with the girls... but Twilight, you really know how to use your fingers.”

“No fair!”

But Shining's protests fell on deaf ears as Velvet licked Twilight's fingers clean. She kissed each of them in turn—first Twilight, then her brother. Twilight could taste her mother's juices on her tongue. “We need to do something about this,” she said. “You're both so hard, and I'm dripping.”

Twilight bit her lip. Her cock was so hard, it practically ached. All this foreplay had only managed to work her up more than she already was. “Say, Mom...”

“Yes?”

“Did Celestia ever say who was the better lay?”

Velvet paused for a moment. “Come to think of it, no, she didn't.”

“Looks like there's only one way to settle this, BBBFF,” Twilight said, idly stroking her cock.

“I guess so.”

Twilight shot him a wolfish grin. “Too bad I'm up three stars to your zero.”

“Actually...” Velvet said. “Shiny kind of redeemed himself in the kissing department. Don't get me wrong, Twilight, you know how to use your tongue better than anypony, but Shiny just has a way of sweeping a girl off her hooves.”

“You don't know the half of it.” Shining stood, and in one practiced motion, hoisted Velvet over his shoulder. She cried with delight as he tossed her onto the bed, flat on her back. With astonishing quickness, he grasped her narrow waist and climbed on top of her, aligning the head of his throbbing horsecock with Velvet's dripping pussy.

Twilight watched with a mixture of curiosity and admiration as Shining began to go to work. His muscles rippled as he towered over Velvet. Leaning in close, he whispered, “I love you, Mom,” before kissing her. While they were making out, he slid his cock inside his mother's snatch. “Oh, stars above… I’m inside you, Mom—I’m actually inside you!” he said. “It feels so good. You’re so tight!” His movements were slow and gentle at first. Velvet's head snapped back, and her moans filled the room. Her limbs shook as she took what Twilight assumed was the biggest cock of her life.

“Get ready, Mom, because I’m gonna fuck you. And I mean really fuck you.” Shining held her with such strength that she could not move even if she wanted to. He only paused when he had slid half his length inside her. And then he started thrusting. His hips pistoned back and forth with perfect, practiced rhythm and enough force to shake the bed with every movement. Velvet cried in ecstasy as her son thoroughly rutted her.

Twilight bit her lip and stroked her cock faster. She marvelled at her brother's technique. As hard as his thrusts were, he never went more than seven or eight inches deep. Twilight could not imagine giving it to a mare that hard without trying to hilt herself. While Velvet's hands erratically groped and grasped at Shining, her torso remained firmly in place, held by Shining's powerful hands. Her tits bounced fast, showing just how hard she was being fucked.

It was not until she cried, “More! More!” did Shining shift his position. He grabbed her wrists, pinning them next to her head. With his teeth clenched, his muzzle screwed up in concentration, he really began to rail her. Over ten inches of hard, throbbing stallion cock slid in and out of Velvet, and Twilight imagined the slight curve in his shaft made their mother feel it even more.

Something snapped within Twilight's head. He can't have all the fun! She took her hard horsecock in both hands and moved until she stood behind Velvet's head. Her cock rubbed against Velvet's snout, and without further coaxing, her mother took the first few inches in her mouth. She leaned forward and grabbed handfuls of her mother's perky tits as she began making love to her mouth.

The sensations of Velvet's mouth wrapped so tightly around her cock sent shivers through her, and it took all the restraint she had to keep her movements gentle. She groped and squeezed Velvet's boobs as she shoved inch after inch of her impressive length farther and farther inside her mother. The tightness of Velvet's throat brought about a whole new wave of sensations that shot through her cock and rippled the length of her body.

Twilight made sure to pull her cock far enough back that only the head remained inside Velvet's mouth, allowing her to refill her lungs before she plunged it back inside her throat. She could see the shaft's visible bump in Velvet's neck when she buried herself inside her. All the while, Shining kept thrusting, managing to fit all but three inches of his length inside her. Twilight noticed the outline of his cock against Velvet's flat stomach each time he finished a thrust.

If Velvet felt any discomfort, she did not express it. Between her well-hung children, she was completely stuffed full of horsecock. Twilight moaned and squeezed her mother's perfect tits harder as her cock gave another sharp twitch. Despite experiencing an incredible maregasm, Twilight had not gotten fully hard until now. Pencil-thick veins throbbed along the length of her completely taut shaft. She grunted as she forced more of herself down Velvet's throat, until her mother's lips kissed the medial ring, which was about halfway down her nineteen-inch cock.

Meanwhile, Shining's thrusts had not slowed. Sweat glistened on his toned body as he gave Velvet the rutting of her life. Twilight was not the least bit surprised by his impressive stamina. Considering he had been fucking sex goddesses for half his life, a performance like this was only natural. As brother and sister continued to spit-roast Velvet, Shining finally looked up from his single-minded thrusting.

An impish grin flashed on Twilight's muzzle. She was so inundated with hormones that her own big brother watching her massive tits bounce and flop around while she throat-fucked their mother only turned her on even more, spurring her to deliver harder and faster thrusts. Shining grinned back. A strand of drool fell from his muzzle. Twilight knew how desperately he wanted to grab her boobs and bury his face in them, but he kept thrusting.

Twilight's thick, shapely thighs began to burn from the exertion. She could not say how long they had been at it, but she could tell how much Velvet was enjoying herself from the occasional whimpers she made around Twilight's hard cock. Somehow not breaking his rhythm, Shining shifted his grip on Velvet from her wrists to her ankles and slowly began to stand, rising between thrusts and leaning forward a little more each time he buried a foot of his length inside Velvet's pussy.

He had soon risen to his full height and propped Velvet's shapely legs against his chest. With her hands free, Velvet began vigorously rubbing her clit with her right hand while clenching a fistful of bed sheets with the left. Twilight marvelled that she was still able to swallow ten inches of dark-lavender cock while Shining was piledriving her. Velvet shuddered, no doubt from at least one body-rocking orgasm, but her son kept up his unrelenting movements for minute after minute.

At last, Twilight noticed his movements grow ever so slightly erratic. His eyes were shut, and his muzzle wore an almost pained expression that bared his teeth. He began to grunt. Twilight bit her lip as she watched him. She knew her own orgasm was not too far off, considering the amount of precum she could feel herself discharging into Velvet's stomach and the sheer amount of pleasure thrumming within her turgid horsecock. The pace of Shining's thrusts remained constant, but their intensity did not. Sometimes, he gave her hard, three-inch movements, and then follow it by sliding most of his length out before driving it back in.

“Unf... Princess Mom, I'm—I'm gonna cum!” he said, burying himself inside her.

The first shot was so loud, Twilight could hear the distinct splatter! deep in Velvet's womb. Her mother's eyes bulged as Shining unloaded the copious blast of his seed. The shot lasted several seconds. He resumed thrusting as his over-engorged cock continued to spew its load. Twilight's mouth fell open. Somehow, thick wads of sticky stallion spunk flew from Velvet's pussy and landed all over her, from her belly, to her tits, to her neck, to her face.

A look of relief and ecstasy covered Shining's face. His eyes were half-lidded as he continued to thrust. Twilight had to remind herself to keep moving her hips as she watched the spectacle unfold before her. She removed her hands from Velvet's tits when a splash of her brother's warm seed landed on one. After licking it clean, enjoying the powerful, salty taste and the scent of the stallion musk, she began jerking the bottom half of her shaft with both hands.

Velvet looked as if she had just allowed several stallions to cum all over her by the time Shining was done. He whistled, wiping a line of sweat from his brow as he released Velvet. Twilight bit her lip. She had never seen a cumshot like that before. Velvet's belly remained flat and toned, but a rivulet of semen still drained from her pussy. Her mother lay motionless while Twilight continued to fuck her, but she soon recovered.

Her hands joined Twilight's around her long, thick shaft, and helped Twilight jerk herself off as she thrust faster. Shining sat back on the bed, refilling his lungs and watching them. He came a lot for a stallion—more than Twilight expected. A sudden jolt of pleasure shot through her body, and she tilted her head back. It was quickly becoming too much for her. Watching her brother cum like that had eroded much of her already waning endurance, made all the weaker by being unable to jerk herself off in the morning like she almost always did.

“M—Mom—Princess! I can't hold it!” Twilight gasped between words. Her cock thickened as it prepared for release.

Velvet's only response was to wring her hands up and down it with greater fervour. Twilight's eyes rolled back and she came, blasting her futa seed directly into her mother's stomach. Her tongue lolled out of her muzzle as the first volley plastered Velvet's insides. It was a full ten seconds before it petered out.

No sooner had her first shot left her flaring cockhead did a second shot, even bigger than the first, chased it. “Oooh, it's soooo goooood!” Twilight moaned as she stroked herself while using her mother as a living oneigh-hole. Strands of excess cum flew from Velvet's flared nostrils; Twilight had filled her to the brim, and still, she came. As she unloaded her fourth massive salvo inside her loving, lovely mother, she felt a pair of hands against her pelvis. She looked down and saw panic in Velvet's eyes.

Hastily, she wrenched her cock free from Velvet's throat and mouth. Over a quarter of a litre of cum spilled from Velvet's mouth, followed by smaller waves as she coughed and spluttered. But Twilight was not finished. She pointed her gigantic horsecock at Velvet's petite, sexy frame like a canon, and kept shooting. Thick, hot ropes of mare-cum flew from her cock, landing all over Velvet's body. She roughly grabbed Velvet's tits and slid her shaft in her cleavage as she spent the last of her seed.

Finally, she leaned back, groaning with relief. Her mother was a mess. Between Twilight and Shining, she had been completely drenched with cum and lay in a pool of seed. Her eyes were glazed over as if she had been concussed. Of all the mares Twilight had exploded all over, she never imagined her own mother to be one of them, or for such an act to feel so hot.

“Damn, Twily, you came a lot,” Shining said. “Do all futas shoot like that?”

“How should I know? I've never met anypony else with my, um, ‘gift.’”

Shining leaned against the wall at the head of the bed. “Are your loads always that big?”

“No,” Twilight said, “sometimes they're bigger. One time, I was so busy, I couldn't find the time to get off for a whole week. I was afraid Rarity was gonna drown... and then she asked me to do it again. But that doesn't matter. How in Equestria did you cum like that? You got it all over Mom, and you didn't pull out even once.”

Laughter filled the room. “Oh, that? It's an old party trick. During my first leave from the Royal Guard, Cadance and I really got into it, having been apart for a few moons. I was giving it to her good, and when I came, that happened. Turned out to be real popular with the mares—especially Celestia.”

Twilight steepled her fingers. “Could... do you think you could teach me?”

“For you, Twily? Anything.” Shining winked. “Just pay the Crystal Empire a visit, and you can practice on Cadance. She won't mind. Trust me.”

Twilight felt her face grow hot, but spluttering from the bed brought her attention back to the present. Velvet at last sat up, a sheet of cum cascading down her body. She wiped the spunk from her eyes. “That—dear Celestia—is that what the other princesses get?”

“Did you enjoy it?” Twilight said, silently reprimanding herself for not telling her mother just how big her orgasms were, especially when she had been pent-up like this.

“Enjoy it?” Velvet sounded confused. “I loved it! That was the most incredible sex of my life. Oh, Shiny, you really know how to give it to a mare. I lost count of how many orgasms you gave me. The way you held me down and just kept going... I felt so weak and helpless. It was wonderful. And Twilight! How can anypony cum like that? There was so much of it, I think you completely filled my stomach with just one shot, and you didn't stop.”

Blushing more fiercely than before, Twilight covered her mouth, failing to stifle a giggle. “Don't give me all the credit. I don't go off like that unless the mare I'm with makes me feel really good.”

“When I asked you two for this gift, I guess I had no idea what I was really asking for,” Velvet said. “I've never been so happy to be so wrong.”

“So,” Twilight said as Velvet began to dry herself with a towel from the closet, “who gets the gold star?”

“It's not really fair, since you never got a proper turn,” Velvet said. “You only got my mouth, so Shiny kind of wins that by default. But after how much he came, I never thought I'd say that you shot way more than him.”

“Twily,” Shining said, “you're still hard.”

“So are you.”

Velvet took several steps back and gaped. Twilight's cock was so hard, it ached. She felt as if she had not gotten to cum in days, despite having just almost drowned her mother. Veins pulsed all along it, and precum had already begun to gather at its tip. She could see that her brother looked just as hard as she felt.

Velvet ran a hand up Twilight's length, her palm bumping against the engorged veins. “But how? Both of you? After all that? I'm dreaming. There's no way this can be real.”

“It's real.” Twilight leaned forward and kissed Velvet. The sickly sweet scent of her own cum filled her nostrils. As their tongues met, Twilight felt Velvet's fatigue from the abuse Twilight had given her mouth and throat. When their lips parted, Twilight said, “You feel so good around my cock, there's no way I can only cum once.”

As she spoke, Shining loped forward and clapped a hand on Velvet's shoulder. “So, you're up for round two?”

Velvet groped Twilight's tits, her gaze fixed on them. “Yes, but I want to feel Twilight inside me. I just don't think my throat can take more.”

Shining spun her around. “Get on your knees. On the bed. Twily?”

“Yes?”

A sly grin crept across his face. “I know we're kinda competitive.”

Twilight arched an eyebrow. “‘Kinda’?”

“Okay, very competitive,” Shining said sheepishly. “But I think we need to work together. This isn't about who's the best lay, it's about giving our princess the best night of her life.”

“You've already achieved that.” Velvet was on the bed, her tail aside and presenting them with her pussy. “But if you can do even better...”

“We can,” Shining said. He moved forward to mount her.

Twilight folded her arms. “Shiny? It's my turn.”

“I know. Who's to say we can't both go at once? I'll take the other hole.”

“M-my ass?” Velvet said. Twilight could not be sure if she was excited or afraid.

“Math was never my strong point—”

“Academics,” Twilight corrected. “Not just math.”

“Whatever. You've got a few inches on me.” He looked over his shoulder and winked. “So, why don't we just give her a bit of the old double barrel? You can stand behind me, and we can fuck her at the same time! She's not gonna miss a few inches since she can't take all of us inside her.”

Twilight took a moment to consider. Only a moment. “Well, not to brag or anything, but I am nineteen inches. I just can't help but wonder if this is a thinly veiled excuse for me to press the girls against your back.”

“Twily!” Shining sounded scorned. “How dare you! It's not thinly veiled at all.”

Shaking her head, Twilight grinned and stepped forward until she stood right behind her brother. She only had to slightly bend her knees in order to slide her throbbing cock under his. Once she had the correct angle, she sidled forward. Her firm tits pressed into his upper back, and she had to grab onto his toned muscles to pull herself closer. Finally, she felt the flat head of her horsecock pressing against her mother's mound. “Ready?”

Shining nodded and placed his hands on Velvet's supple, fuckable ass. “Go.”

They slowly leaned forward. Twilight bit her lip as she felt her mother's pussy eagerly accept her throbbing member. Velvet moaned loudly as two titanic horse dicks penetrated both holes, sliding deeper and deeper within her. Twilight shuddered. In addition to over four inches of length, she had a noticeable amount of girth on her brother, and because of this, Velvet's petite body felt so tight around her.

“Okay, Princess Mom,” Shining said. “I dunno how big Dad is, but you've probably got four times more cock inside you than you're used to.”

“So. Big!” Velvet said.

Twilight could feel her mother trembling. And then Velvet began to move, slowly at first. She worked her hips, rocking them back and forth a few inches. With her dictating the pace, Shining followed her lead, his movements suggesting none of the speed or force he had used just minutes before. Twilight mimicked him until all three lovers fell into a rhythm.

Twilight could not help but grope her big brother as their cocks slid in and out of Velvet. His body felt so perfect, so statuesque on her fingertips. She could feel every defined detail of his torso, and she pressed herself harder against him, her boobs squishing between them. Velvet soon began to move faster, and a loud thwack! resounded throughout the bedroom. Twilight did not need her brother to prompt her to thrust harder and faster.

As they picked up the pace, Shining turned his head. Twilight leaned forward and kissed him. Neither of them wasted any time with teasing. Their tongues thrashed about in each other's mouths, and Twilight moaned into his muzzle as they kept rutting Velvet without so much as the slightest falter.

“Ooh! Give it to me!” Velvet wailed. “Give it to me!”

And they did. Every time Velvet clenched Twilight's cock from a powerful orgasm, a shock wave of pure ecstasy shot through Twilight. But instead of cumming, she only kissed her brother more passionately, groped him with greater urgency, and kept sliding her cock back and forth, no matter how tight Velvet's marehood squeezed. She regretted not kissing Shining until now. He slid his tongue deep into her mouth at just the right time, and let her tongue into his, sucking on it when it was far enough inside.

As they continued to make out and rut Velvet, Twilight felt a familiar pressure begin to mount in her cock. But before she could let it build, Velvet moaned loudly and collapsed on the bed. Twilight and Shining broke their kiss, withdrew their throbbing horsecocks and looked at her. She sprawled flat on her stomach, her legs askew.

“Mom—I mean, Princess—are you okay?” Twilight said, missing the feeling of Velvet's pussy already.

“Yes, Twilight, I'm all right,” Velvet mumbled. “You two just have so much cock, and so much stamina. I don't think I'll be able to walk properly for a week, and you're not done yet.” With laboured movements, she rolled onto her back. “Twilight, can you take me now, like your brother did? Just you. I can't take both of you at once anymore—it's too much for my poor ass and pussy.”

With a nod, Shining stepped aside. Twilight helped her mother prop herself against the wall. They shared a tender kiss, and Velvet played with Twilight's breasts as Twilight aligned her cock with her mother's snatch. Gently, she slid herself inside. Their snouts touched, and they gazed into each other's eyes as Twilight moved her hips back and forth, sliding only six inches in and out at a time.

“Deeper, honey,” Velvet urged.

Twilight allowed a few more inches to penetrate Velvet with each thrust. She groped Velvet's wonderful curves, squeezing and occasionally gently slapping her ass. Eventually, Velvet began to regain her strength, and rode Twilight's shaft. “I love you, Mom,” Twilight said. Velvet's only response was to kiss her again.

“Hey, Twily,” Shining said from right behind her. “Did I ever tell you how Flurry Heart was conceived? Cadance painted herself purple and role-played as you, Twily. It was the hottest sex I've ever had.” Before Twilight could answer, she felt a pair of strong hands on her ass followed by an enormous horsecock sliding deep inside her pussy. She yelped, and her tongue lolled out of her mouth.

There was a loud slap as Shining hilted himself inside her. He squeezed her ass harder and pushed the cheeks up in an effort to slide more of himself inside her. Twilight could not stop her pussy from cumming from the unexpected jolt of pleasure that wracked her body. “Aah, BBBFF!”

“Mmm... Twily, that’s what Cadance said, too. And you took it all, too. Ooh, so tight...”

“You're so huge, Shiny,” Twilight finally managed. “Bigger than any, uh, ‘plot device’ I've ever used.”

Shining spanked her hard. “If I had a bit for every time a mare told me that, I'd be a prince.”

“But you are a prince.”

“Exactly.” And then he began to fuck her without mercy, just as he had done to Velvet. He grasped every bit of her he could find, sliding his entire length in and out of her dripping pussy, his sizable balls slapping against her at the end of every thrust.

Twilight's massive tits bounced in Velvet's hands, and she continued to penetrate her. She had truly never felt anything like this before. Her cock burned with almost unbearable pleasure, and her pussy was completely full of cock. Each time Shining hilted inside her, a fresh wave of ecstasy crashed into her. She felt weak in the knees, but forced herself to keep moving.

“Yeah, it's so good!” Shining said, grunting between words. “Now I've fucked every big titty alicorn princess!”

Twilight was too overwhelmed with pleasure to respond. Precum leaked from her cock in a steady stream. She felt like she would explode at any moment, but somehow managed to hold on. So this is what a real cock feels like. Truly, no dildo could compare to it. No wonder why my lovers want me inside them so badly.

“Fuck, I'm gonna cum!” Shining said, his voice strained.

Twilight’s eyes widened as her big brother blasted his big load all over her insides, instantly sending her pussy into a mind-shattering orgasm. Shot after shot splattered against her deepest reaches, sending shock waves of pleasure through the likes of which she had never felt before. Shining kept cumming, grunting as his seed mercilessly pelted his sister’s insides. It was at least a full minute before Shining's orgasm subsided.

“Did you enjoy fucking your little sister, Shiny?”

“Mmhmm.”

“Good,” Twilight grunted. “Because I enjoyed it, too.” She continued to bury herself inside her mother, her movements short, forceful, and erratic. She knew she could not hold herself back for much longer. Her BBBFF unloading so much cum inside her was overwhelming, and she could still feel his turgid cock jammed deep inside her pussy. “M-Mom, I'm gonna cum,” she whimpered.

Velvet's legs locked around Twilight's back. “Do it! Fill your princess with your cum!”

“Ooh!” Twilight's hips gave several hard jerks, and her cock swelled as the pleasure became too much. “It's coming, and it's a huge load!”

Twilight leaned forward, shoving a foot of herself inside Velvet, and came. She groaned with relief, and bucked her hips even before the first shot had been spent. Her cock, squeezed so incredibly tight by Velvet’s orgasming pussy, remained inside her prone mother as shot after shot unloaded deep inside her. Velvet placed a hand on her stomach that began to expand from the sheer volume of semen being pumped into her. Twilight's cock was much too thick to allow any of it to escape. Her belly kept growing as a series of feminine grunts escaped Twilight's throat.

“Pull it out—please!” Velvet said when she looked like she had swallowed a whole watermelon.

Taking her pulsing horsecock in both hands, she wrenched it out. A fusillade of cum spat from its flared head, splattering against the ceiling. Twilight forced her cock down, and fired another half-dozen shots that once again completely coated her mother in cum. At last, her orgasm ended, and she shook the last few drops of semen from her softening cock. A steady stream of her seed gushed from Velvet's pussy.

Shining grabbed her ass and stole a kiss. “That was quite something, Twily. You came even more than you did the first time.”

“So... Princess Mom, who won this special round of Sibling Supreme?” Twilight said.

“You are both so good in your own special ways,” Velvet said weakly. “I don't think either of you are better than the other. The real winner tonight... was me.” Her eyes fluttered shut as she passed out, utterly spent.

“You know, Twily, I'm okay with that.” Shining squeezed one of Twilight's breasts as he kissed her deeply.

Twilight could not stop beaming. “Me, too, BBBFF.” She took a moment to bask in the afterglow. “So,” she eventually said, “good thing we used that contraceptive spell, right?”

“Uh, I didn’t use that spell,” Shining said. “I thought Mom cast it.”

The colour drained from Velvet’s face. “I thought your sister cast it!”

The three forbidden lovers stared at each other for almost a full minute before they all said, “Uh oh...”
