At her Brother's Command

Clad in a simple blouse and a modest skirt, Twilight made her way briskly down the corridor. She was nervous yet excited, wringing her hands together and breathing a bit more quickly than normal, berating herself for not having been ready right there as the knocks sounded again. She sped up, putting perhaps more strength than necessary into it, and her hooves clinked melodiously on the crystal floor as she stepped her way to the door. Though she was mostly used to it by then, after years of living there, she still marvelled at the way her palace would almost sing when struck certain ways. Maybe it was just how crystal was, or maybe it was magic. She'd have to look more into it sometime, if she ever found the time to.

She reached the door and opened it with her magic, smiling brightly at the ponies behind it as the late afternoon sunlight flowed in. "Shining!" She practically threw herself around her brother, who still stood a good head taller than her even after her ascension. "Cadance!" she added, still clinging to Shining but turning her attention to his wife. She didn't reach out to her, or begin their traditional dance, as Cadance wasn't exactly in a good disposition for either at that moment. "I'm sorry I couldn't meet you at the train station."

"Don't worry. It's a pleasure to see you again," Cadance said, smiling warmly. She wore a loosely fitting pair of shorts that left her legs bare, and a small tube top around her chest that her swollen breasts pressed into, showing the ring-shaped piercings on her nipples. Not exactly royal attire, but she wasn't there formally, and most importantly it meant her swollen belly wasn't hindered by clothes that wouldn't have fit her anyway. She rested a hand over the curve of it, rubbing it up and down slowly.

"I missed you, L.S.B.F.F.," said Shining, hugging Twilight back. He ruffled her mane with one had on the back of her head and nuzzled his face into hers, before planting a brotherly kiss at the base of her horn that made Twilight blush a little.

Twilight moved back from the hug and bent down to look at Cadance's belly. She reached out with a hand, hesitated, then placed it besides Cadance's after a nod from the pregnant mare. She held it there, and after a moment she giggled. "I think I felt a kick." Cadance smiled at that. Shining was also smiling, though his eyes were pointed elsewhere. Twilight sighed, straightening again and making his gaze move back towards the back of her head. "To think I'll be an aunt again so soon. And I'm sure Flurry will love having a sibling to play with! Her own little B.F.F.!" She beamed. "Do we already know-"

"A filly," Shining said, anticipating her question. "Flurry will have an L.S.B.F.F. too."

"We're so sorry Flurry couldn't come too," said Cadance. "She's a little sick, and Sunny is taking care of her right now. I would have brought her, but she would have monopolised the whole trip."

"And you're tired enough already from the pregnancy," Shining added, resting a hand on his wife's shoulder.

"It's okay," Twilight said, "I understand, and I'm also sorry I invited you when Spike couldn't be here. Maybe we'll pay a visit too next. It's been a while since I've been to the Empire. And I still haven't gotten to see Sunny since, well, you know." She trailed off. "She seemed really happy from her letters though."

"She is," Shining confirmed. "Everyone in the Empire is a lot happier lately. I'm sure you'd love it there."

Twilight smiled. Then, after a moment, she shook herself. "Oh, do come in." She motioned for them to walk inside. "I don't want to keep you here too long, I'm sure you're tired after the trip."

"Hah." Shining chuckled as he levitated their luggage and walked in. "Your brother doesn't get tired that easily, Twi."

Twilight watched him march on, rolling her eyes in bemusement. Then she turned to Cadance again, who looked far more worn out than he did. "Are you sure you'll be alright? Is there anything you need?"

Cadance shook her head. "Don't worry about it." She began to follow Shining inside, but stopped after just a couple of steps. "Oh. Before I forget." She reached out with her magic and opened the backpack nestled between her wings, pulling out a squared gift-wrapped package that looked a lot like a book. "A little something from both of us. I'm sure you'll enjoy it."

Twilight took the book in her hands, smiling. "Oh, Cadance. You didn't need to." Cradling the book to her modest chest, she leaned forward over Cadance's belly and kissed the older mare on the cheek. "Thank you."

Cadance smiled back at her. "Think nothing of it." She turned, and followed behind Shining into the pleasantly cool air of the castle's interior.

Clothes were off the moment the door to their room was locked, and soundproofing spells came on just as Cadance's mouth wrapped herself around the tip of Shining's hardening shaft. Kneeling before him, looking up at her King with worshipful adoration, she reestablished the magical link between their horns and plunged her throat down on his massive cock.

It felt like breathing again for the first time after holding her breath too long. Finally she could be herself again. Finally she could serve and nourish her King again. She moaned around the cock stretching her throat and her pussy gushed out as she played with her tits.

Shining gave a satisfied grunt as well, grabbing hold of Cadance's horn and slamming her face against his crotch as he siphoned so much magic from her so quickly the ethereal connection between their horns shone like an arc of electricity in the air. "There we go, you slut. That's where you belong!" For a little bit he just kept fucking and draining her, while Cadance barely stayed conscious and made a mess on the floor. Finally, Shining pulled her head off his cock, letting it spring free again. "I needed that," he said, taking a deep breath and shifting the magical flow back to a more measured drain.

Cadance took a series of rough pants, leaning forward to keep herself up with Shining's strong legs as she nuzzled and licked his fat balls. "I hated having to keep magic in and clothes on for so long. How did the old me ever manage?" she wondered between a kiss to Shining's nuts and the next.

Shining stretched his shoulders, flexing his muscles as he once more felt power flowing through his body. "Come next week, you'll never have to do that again. Just a while longer." He leaned back and took hold of his cock with one of his hands, slapping it against the side of Cadance's face. "You remembered to give her the book, right?"

Cadance planted a wet kiss against the tip of Shining's cock. One of her hands was still twisting her pierced nipples, and the other went to stroke Shining's length. "I did." She focused her gaze on the shaft in front of her. "When should I turn on the spell?"

"Give it a moment. I don't want you to mess it up because you're drained." Shining thrust forward into Cadance's muzzle, frustration evident on his face. "If it wasn't for those stupid Elements I'd have Twilight gagging on my dick right now." He grit his teeth, but forced himself to calm down with deep breaths before anger could get the better of him. "No matter. They'll be dealt with soon enough, and Starlight too." He forced Cadance's mouth open with his magic and plunged into her throat again, distracting himself from the thought that his powers were in danger of being challenged and focusing instead on how inevitable his ultimate victory was.

Cadance took him in, squeezing his cock with her throat. How she'd missed the feeling of him fucking and using her, and how she'd hated having to pretend in front of Twilight and during the trip. The quick fuck they'd had in the train's bathroom had not been nearly enough. She let her mind go blank for the time being, relishing her utter submission. Her King would wake her when he needed her thinking.

Twilight settled down on her bed with a drawn out sigh. Be it the hot weather or the pent up tension of waiting for Cadance and Shining to arrive, she was feeling more tired than she thought she'd be. Maybe it was also Spike's absence. He was at a Power Ponies con in Manehattan over the weekend, staying there with Big Mac. Half of her was worried about his well being, perhaps being overprotective, and half of her was worn out from having to take care of everything he would usually do himself. She'd never thought dusting shelves could be so taxing, but with him gone she'd had to make sure the palace was spotless on her own. Starlight wasn't to be trusted with cleaning anything after the last time. She was a little peeved that had left her no time to go meet Cadance and Shining at the station.

Leaning into her pillow, she looked to the wrapped-up book on her nightstand. She hadn't opened it yet. After a short dinner, Shining and Cadance had retired to their room, right next to hers, tired more than she was from the long trip and the hot weather. The latter was probably particularly bothering for them, since they were used to the Empire. It explained their light clothing all the more. They'd collectively decided they'd see each other the next day, and discuss what to do with a clear and rested mind.

Twilight took the book in her magic and carefully undid the wrapping. The cover art looked exotic, but the title held no hints as to the contents, and the rest of it was bare. It was a little worn, but that was a good sign. Nothing quite like a book worth rereading often. Pushing herself deeper into the pillow, she opened it on the first page and began to read, barely aware of a quiet and wet sound of something vaguely like tapping coming from beyond the wall.
