At her Brother's Command

Twilight slowly opened her eyes. The room was dark, with only a little light making it in past the blinds. It was hot, and it smelled of what she'd been getting busy with the night before. Which was normal. It was normal for single girls to touch themselves. The room needed some air though, so she flicked her horn and opened the window, letting the sunlight and fresh morning air in. She lay in bed a little longer, until she smelled something different coming from downstairs. Something good, though she did not recognise it. But she was sticky and sweaty still. With a groan she stood up, tossed her clothes to the floor, and went to take a shower.

A couple of minutes later she was making her way downstairs, wearing a pair of shorts and a little top that left her midriff exposed. The weather was getting even hotter somehow. Her dreams had been more confused than the previous night. Full of flashing lights and buzzing sounds. But they had been strangely relaxing too. She felt deeply rested and ready to take on the day, even if looking outside she'd realised it was still surprisingly early and she couldn't have slept all that much. She'd considered taking the book down with her to breakfast, but she'd figured reading it in front of Shining and Cadance could easily end up being too distracting, even if they might have appreciated knowing she liked their gift.

"Good morning, everypony," she announced as she stepped into the kitchen. Shining was sitting at the table, wearing a tight T-shirt that clung to his sculpted muscles and broad chest and left his large, strong arms bare. Cadance was in front of the stove, her skirt hiked up to give a full view of her wide and naked backside, busy humming as she cooked something, bent forward so her ass- Twilight blinked. Cadance was at the stove, standing straight, wearing a short skirt that covered her curves and a small tube top that left her back visible, cooking something. It smelled good.

"Good morning, Twi." Shining looked at her with a smile and he stood, then walked over to embrace her, pressing her into his muscled body as he passionately kissed the top of her head. "We thought we'd wait for you and make something we can all enjoy together." He held her there, pressed into him.

Twilight didn't mind. She liked being close to him. She'd missed her Big Brother deeply. Ever since becoming an Element first, then a Princess on top of it, and especially when she'd had to free him from Chrysalis and help him against Sombra, she'd missed him being the bigger, stronger sibling that she could lean and depend on. It was nice to know he was there for her, her big strong brother again, even if it was just a hug. "What are you making?" she asked, placing a hand over his chest to feel his heartbeat.

"Scrambled eggs," Cadance announced, turning around with a pan held in one hand and a wooden fork in the other, poking the white and yellow mass she'd just taken off the fire.

"Without cheese, don't worry," Shining said.

Twilight smiled and took a seat next to him, waiting for Cadance to put the eggs on the central plate so she could take her own portion.

"You know," Cadance said as she did that, "the secret to making good scrambled eggs is the milk. It helps them stay soft. Otherwise you're just making a messy frittata." She put the empty pan back on the stove. "Go ahead, serve yourselves."

Twilight took about a fourth of the eggs for herself. Shining took half the total, twice as much as Twilight had. Twilight arched an eyebrow at that. "Someone is hungry, huh?"

"Your brother is a big boy, Twi," Cadance said as she took the last fourth. "He needs all the energy he can get."

Twilight frowned for just a moment. She supposed that made sense. "Shouldn't you get more too, though? You're eating for two after all."

"Don't worry, I get more than enough to eat already," Cadance said.

Shining cut in before Twilight could properly think about that. "She's been raiding the palace's pantry repeatedly as of late. She may have done the same here, actually." He shot Cadance a glare. "Maybe your sister in law is forgetting just where we are right now."

Cadance shrank a little under his gaze, blushing and giving an awkward chuckle. "Sorry. Cravings. You know how they are. Or, well, you..." She trailed off, and stuffed another forkful of scrambled eggs into her mouth.

Twilight chuckled. "I swear, if-" She was interrupted by the sudden sound of polite yet firm knocking at the door. She perked up. "Oh. I'll go see who it is. Be right back." With that, she stood.

Once she was halfway down the corridor, out of earshot, the sounds of Shining spanking Cadance for her misstep filled the kitchen, soon followed by her moans.

Twilight, meanwhile, was at the door after just a brief walk. She opened it just after another set of knocks. "Yes? What is it?"

Rarity stood there, prim and proper even in the sweltering summer heat. She wore an armless burgundy blouse with frills along the sides and over her shoulders, a diagonally cut skirt with a gradient from black to purple going in the same direction as the cut, and a white belt studded with blue gems between the two. She also had the Element of Generosity hanging from her neck. "Oh. Hello, Twilight. Your brother is available, right?"

"Uh. Sure. Do come in." Twilight stepped to the side. "Is everything alright?" She looked to the gold and purple necklace resting above Rarity's not insignificantly sized bosom, made to seem larger than it already was thanks to a push-up bra.

"Yes, yes," Rarity said, stepping inside. She had a look around, quirking an eyebrow. "Huh. When did you change the walls? Actually, how did you change them anyway? If I knew of a spell to make gems lighter in colour I could-" She shook her head. "Never mind, sorry. Light blue is a nice colour. Anyway, I have a business meeting later, so I came early." She looked to Twilight. "Are you alright? Rainbow said it was important when she told us to bring the Elements, but it's not something serious, right?"

Twilight hesitated. "I..."

A new voice cut through the air. "Rarity!" It was Starlight, coming down the corridor, wearing a short miniskirt and a top with a deep V cut. "Shining and Cadance told me about wanting to see the Elements. They're waiting for you now, just down the corridor and to the right."

"Thank you, Darling." Rarity turned to Twilight. "I would love to stick around to chat, but I'm in a bit of a hurry, as I said. Perhaps later." She turned again, and strutted down the corridor in that way she always had about walking like she was the single most important pony around, regardless of where she was.

Twilight watched her go. She felt confused, but also sleepy somehow. Or perhaps sleepy wasn't the right term. But there was a tiredness to her thoughts, if not to her body. A sudden bout of fog as she tried to remember why Rarity was there. She turned to the door and saw the bright sky outside, and felt the cool air on her skin. Perhaps a walk to clear her head would-

Starlight's hand wrapped around her arm and kept her there, before Twilight had a chance to step out of the castle. "They won't take long," Starlight assured her. "You wouldn't want to keep your brother waiting. He came all the way here just for you."

Twilight's head was only getting foggier. Her brother. Right. She let Starlight close the door and drag her deeper back into the castle. Wait for Shining and Cadance to be done with Rarity. Rarity... Not worth thinking about it. Not when thinking was so hard. She should find something to pass the time instead. "You're right."

Starlight smiled at her. "Come on. You should at least finish your breakfast." And she led Twilight farther down the corridor, subtly bathed in the weak light blue glow filling its crystal walls, still gripping her arm tight with her hand.

"Oh, Rarity, there you are," said Cadance, leaning against the wall just outside the kitchen. "Shining went back to his room. We should go meet him there."

Rarity curtsied before Cadance. "Greetings, Your Highness. It is always a pleasure to meet you. Are you sure you want to accompany me? I wouldn't want you to exert yourself too much in your conditions." She looked to Cadance's belly with a smile.

"It's no matter," Cadance said. "Come on. This way." She began to walk on deeper into the castle. Rarity looked at her go, swaying her hips and making her fat ass jiggle with each step. Cadance's horn was glowing, a pretty light blue shine. Rarity walked after her. "Here we are."

Rarity was in front of a door. She didn't remember the walk there all that well, or maybe at all. She couldn't focus well. It felt too hot in there for that. Maybe she should take off her top, like Cadance had. Sounds were coming through the door. She hesitated for a moment, but her hand was already on the handle. Something pressed into her back. Something glowed at the side of her vision.

Rarity was inside the room. She was on the ground. Her knees hurt a bit, and her palms did too. Had she been pushed? The room was dark, but there was a light pulsating inside it, and a buzzing sound too. But it wasn't the loudest sound. There were other ones too. Wet, squelching, slapping, panting, moaning. Dazed like she'd been hit in the head, she shook herself and looked around.

There was not much to see. Her Element lying a short distance to her side. The door closed behind her. The luggage stuffed into a corner of the room. The glowing crystal on the desk, taking root into the wood and into the wall. All that she saw, but she didn't pay much attention to any of it. Instead her eyes were on the only other two ponies in the room, up onto the bed.

The only face she could see clearly was Shining's, but she recognised the mare beneath him easily regardless. Her toned blue body, athletic wings, and unkempt rainbow tail made who she was apparent, even if that was just about all that Rarity could see of her. Of course, even in the darkness the sound of her moans would have given her away. Rainbow Dash had her head, neck, and shoulders pressed into the bed, her back rising up like she was doing a shoulder stand candle pose, but curved in instead of straight, looking far messier than proper exercise as a result. Her arms were splayed out over the covers and her legs too were spread open and bent, though that was inevitable with Shining's in the way, pressing down on them. He had his broad hands gripping her pert ass and his hips pressed against hers, and Rainbow's legs hooked up around his own as he moved her body back and forth like she was a piece of training equipment. And with every motion he made her cunt slide around his cock, the sound of their genitals dragging against each other loud as the sheer size of his shaft kept her walls stretched and clamping greedily down on him.

Rarity stared at the display for a few seconds, her mind completely empty. Then, finally, things clicked into place, as the memory of the spell Cadance had used on her before leaving fully came in. Rarity tore open her dress and left it in tatters on the floor. She had a cock to worship.

"What scene are you on?"

Twilight jumped in her seat. Starlight had brought her to the library to wait for Cadance and Shining, and had also graciously brought her the book so she could keep reading as she waited. Twilight realised, as she panted and shook, that she'd been so taken by the story she'd almost started to touch herself again right there. She hadn't heard Cadance coming in at all, either.

Cadance just stared at her with big, friendly eyes surrounded by a hefty dose of makeup, fluttering her long lashes as her glossy lips curved themselves into a cute pout.

Slowly, Twilight calmed down. She cleared her throat, and set the book aside for a moment. There was nothing wrong with telling her. Cadance had gifted her the book, had read it herself, and wanted to know if Twilight was liking it. Which she was. They were both adult mares, discussing things it was perfectly normal to discuss with close loved ones and ponies they could trust. It didn't have to be a burden. It would feel good to let go. It wasn't wrong to care about her feelings and not about what ponies might think.

Twilight opened the book again to check. "I'm about halfway through, I think. It's a bit of a wind-down chapter. There's no new characters or really any plot development, it's mostly just known characters interacting right now." She swallowed. She knew what Cadance wanted to know. "It's the banquet scene. The orgy right after it." She realised she was shaking a little. "You know. The one where the King has all his captured, broken slaves servicing him together." She had more to say about what was happening in the story, but her mouth was suddenly dry.

"I really like that scene." Cadance leaned forward in her seat, surprising Twilight with how casual her tone was. "It's a good reminder of everything he's done and consolidates it well, instead of having the individual conquests only exist within their own scenes. Plus it's just really hot." Her voice slowly but surely morphed into a husky purr. "I adore the image of all those mares kneeling and crawling before him. The reverence they display as they service him. I just love the part where they all worship his cock."

Twilight trembled, and had to force her breath to move again after it had gotten stuck in her throat. "I don't think I'm quite at that point yet." Cadance was being so brazen. Was that what being a mother and wife was like? Was it really so liberating? Twilight tried to change the subject. "How long until Shining gets back?"

"Shining gets back when he pleases." Cadance's response was snappy and cold. But she cheered back up a moment later. "Him and Rarity have something to discuss. Like we told you, we're trying to figure out if there's some connection between the Elements of Harmony and the magic of the Crystal Empire. Thank you again for having them all called here."

They were discussing the Elements and crystals. Twilight had called her friends. Of course. Yeah. How had she forgotten about it? It was probably the heat. Summer made it hard to focus. It was a good thing Cadance and Shining were there to refresh her thoughts if she forgot something again. It was good to have them around. "Is there something you'd like to chat about or do while we wait for him?" Twilight wouldn't have minded getting back to the book, but it wouldn't have been nice to do so while Cadance was right there.

"Actually..." Cadance leaned forward even more, and that made her heavy tits push downwards against her top as gravity pulled them towards the ground. "I was thinking we could have a little chat about him. You know, sister to sister."

Twilight smiled. She wouldn't have wanted to talk about Shining behind his back, but she was sure nothing Cadance could say about him would count as that, and the idea of chatting about him sounded appealing. There were surely a lot of things they could both say on the matter. "Sure. I think I could like that."

"Great." Cadance stood straight again, making her tits bounce, and scooted a little closer to Twilight, dragging her large and barely covered ass over the couch. "There's so much I'm curious about, and so much I want to tell you. Have you seen his muscles lately? He's been training harder than ever." She looked into the distance with a dreamy expression. "It brings me back to the days when we were still students. He's even better now than he was back then."

Twilight chuckled into her hand. "You really are in love, huh?" She could swear she could practically see hearts in Cadance's eyes as she thought of Shining.

"How could I not be?" Cadance focused on Twilight again. "Shining is so strong, and so beautiful, and so smart, and he's just so damn fucking hot. I don't think there's a single mare out there who wouldn't envy the position of being with him." She leaned in close again, this time to whisper into Twilight's ears. "Especially once they found out how good he fucks."

Twilight blushed as Cadance drew back. Details of that kind weren't exactly what she wanted to hear. Of course, she knew Cadance and Shining fucked, the proof was right in front of her, but still it was a bit like being made to think about one's own parents having sex. It was one thing to know, and a whole other to be forced to visualise her brother, naked, bulging muscles glistening with sweat, bent over a mare, thrusting into her, taking her hard, his fat cock- Twilight gave a sharp, deep exhale, coming back to herself. She felt hot. She hadn't been... She'd thought about similar things before, and they hadn't... She closed her eyes to try and focus, only for a new image of Shining's chiselled body and huge throbbing shaft to flash before her vision. She ground her hips together, and opened her eyes, startled. "That's..." She tried to think of what to say. It was hard. Like Shining's- "That's nice to know. For you. Yeah." She cleared her throat. "I'm glad."

"Oh, yeah." Cadance vigorously nodded. "And he's got so much stamina, too. You wouldn't believe. I don't think he'd ever need to stop if it wasn't for other things needing his attention."

Twilight was blushing harder, but her nethers weren't getting any less damp. It was the damn book still lingering in her mind. It was... Why was it so hard to think all of a sudden? She shook her head. Had she zoned out again? She tried to take deep breaths to steady herself. Where was she? Right. Talking with Cadance. "That- That is also good. Um, I think." She gave an awkward smile. "I hope he's not too much for you." Her blush grew fiercer. But she wouldn't get a better chance to approach the subject, and Cadance and her trusted each other, and she had heard, and... "I, uh, I heard you two going at it last night." She cleared her throat. "I think."

Cadance smiled at her. There was something different about that smile, but Twilight couldn't tell what. "Oh, don't worry about it, Twi. Shining is a lot, yeah. In a lot of ways." She raised her eyebrows a couple of times. "But I do like him that way. And if he's ever too much for me, well..." She stretched, pushing out her chest. "It's the present day, Twilight. No reason a stallion can't have a little extra fun if everyone involved is okay with it."

"Hey, Twi!"

But Twilight didn't respond. She was sitting on the library couch, staring at the glowing ceiling. Before Pinkie could call to her again, Starlight pulled her hard away from the door and deeper into the corridor.

"Aww. Is she taking a nap?" Pinkie's Element bounced up and down in time with her tits with every springy step she took along the way. She was definitely the chubbier out of her friends, but nowhere near as much as her sugar consumption levels should have landed her at. She wore a pair of long striped socks, a flower pattern skirt down to her knees, and a plain soft yellow T-shirt.

"Shining and Cadance are this way," Starlight said. She wasn't wearing a bra, and her nipples pushed against her blouse. Her mane was messy, and her face had some spots where something had dried on it.

Pinkie just shrugged and followed along. It wasn't her business what ponies got up to if they were happy and no one got hurt. She looked around as they moved through the castle. "Ooh, pretty. Since when do the walls glow?"

Starlight didn't answer that.

They got to the guestroom after less than a minute of walking. Pinkie leaned against the door, pressing her ear into it. "It sounds like a party in there."

Starlight didn't answer. Starlight didn't look like she'd even heard Pinkie, and there was an odd and mechanical jerkiness to her motions, a hazy emptiness in her eyes. Pinkie noticed that, but before she could react Starlight had already opened the door and pushed her inside.

Pinkie looked around. The room was dark, yet the crystal spreading over the desk and into the floor was strangely bright. Rarity and Rainbow Dash were naked on the bed, lying on their knees one on each of Shining's sides, running their tongues up and down his cock as they bent their waists down and stretched forward to reach it while resting their hands on his muscled thighs. He wore their Elements over his shoulders like some sort of hunting trophy.

"Ooh, an orgy! A surprise orgy! You know I love surprises!" Pinkie got to her knees and moved before Shining, who was sitting at the edge of the bed. He looked at her, speechless, quirking an eyebrow.

Before anyone else could say anything, Pinkie opened her mouth and took in both of his nuts. From her spot in the corner Cadance stumbled, like she'd been struck, staring wide-eyed at Pinkie. "Well I'll be..."

Shining looked at Cadance, very pleased with how Pinkie's mouth felt around his balls, her tongue running over them expertly making his cock throb. "You could stand to learn a thing or two from her, slut."

Pinkie stopped licking his sack and tried to draw back, to tell him that wasn't very nice of him and he should have warned her in advance if that was going to be one of those kinds of session. Cadance's spell hit her before she could speak.

"Goodnight, Twi." Shining planted a kiss on her forehead, then closed the door and walked away.

Twilight stood in the dark in her room. They'd had dinner together. She could still feel the bits of food in her mouth. She couldn't remember it all too well. Things were a bit of a blur in her mind. Maybe she needed a bit of a break. Maybe a proper vacation would help. She couldn't really do any Princess stuff in that state.

She was suddenly aware that she was clutching her book. Pressing it into her chest. Rubbing her stiff nipples against its hard cover. She bit her lip. It wouldn't hurt, right? Shining and Cadance were going to bed anyway. To have fun with each other. And maybe one of her friends was... No. Twilight shook her head. That was a silly thought. She rubbed her thighs against each other. She could hear muffled noises and shuffling from the other room. It was an arousing thought, even if maybe it shouldn't have been.

She walked back to her bed, settled down onto it, and spread her legs. Her clothes came flying off in her telekinetic grip. One hand cupped one of her tits, the other went to her crotch. The book floated before her, lit by her magic's glow.

The King sat on his throne. He looked a bit like Shining did. There was nothing wrong with that. Shining was just the best physical example Twilight had. He was strong and muscled, like the King. He had a huge cock, like the King. Twilight thought of every half glimpsed hint of his bulge back when they lived together, of the way his sized filled out his swimming trunks when they went on vacation together. That had been impressive already, but Cadance had told her that was just his soft length.

The King held a witch who'd dared challenge him by her torso, upside-down, and roughly shoved her up and down with her throat around his cock. She was practically a toy to him, her body his plaything, her powerful magic completely useless as her brilliant mind was far too scrambled by his physical domination. And her coat looked a nice shade or purple, reddened by his blows, her fat tits and ass jiggling as he made use of her. Twilight gritted her teeth, and her moans joined those coming from the mares in the other room.
