Dusk Shine's New Gleam

As Captain of the Royal Guard, Gleaming Shield had had cause to be in the rooms of Princesses Celestia, Luna and Cadance on multiple occasions. Contrary to popular opinion, the three princesses did not have room themes corresponding to their domains and colour schemes. Instead, the three had rooms modeled after different seasons, with Celestia’s room following the rich reds and golds of autumn, Cadance the fresh greens of a new spring, and Luna the greens, browns and blues of a deep summer.

The decorators had been quick to move on Dusk Shine’s new quarters. Minimalist though his tastes may have been, the whites and blues of a winter day seemed to suit him just fine. The sparsity of colour, Gleaming decided, was also effective in negating his occasional obsessive tendencies. Her mother had given up after the third time Dusk had whined as a colt about clashing colours in their family home and let him choose the colours instead.

“Hey sis,” Dusk said, grinning goofily. Gone was the regalia that had adorned head, wings and body the day before. Now he wore no clothes, and the wings were impossible to not notice. “What brings you here?”

“Oh, just checking up on things,” Gleaming said in a sing-song tone that made it clear that she was lying her flanks off.

Dusk frowned. “I doubt we’ll see a repeat of the wedding incident. She would be foolish to try again,” he said, completely missing his sister’s tone of voice. “You don’t need to keep beating yourself up over that, Gleamy. Say, I thought you hoofed over duties for a few days over to your vice-captain. Are you returning to your post or just working part-time today?”

Gleaming Shield sighed. Of course, even as a prince he’s just so dense sometimes. Let’s see if he understands this. She sidled up along to Dusk, and said, “Oh no, I’ve finished work for today. I just happened to miss my big brother, and figured we should get some time alone together.” Gleaming couldn’t purr like a cat, but damn if she didn’t try getting as close as possible.

That got his attention, and Dusk started squirming. Gleaming was mildly disappointed that the urban legend about pegasi wingboners was just that, an urban legend. She would have been so delighted to see her brother’s wings extend up right about now.

Well, let’s see if she couldn’t get something else of her brother’s to extend.

“Oh, oh. That’s what you meant,” Dusk said with a red blush to his cheeks. “We’ve only had a couple of opportunities in the last year, have we?” He looked over at his sister, giving her a closer look. “Now that you mention it, I really am larger than you now. Who's the shortstuff now?” He teased.

Gleaming nodded, ignoring his last remark. Her head only reached up to Dusk’s withers, where only a few years before she was taller than him. How things had changed.

Dusk continued, “You know, Rainbow Blitz teases me a lot. He keeps bragging about these twin mares on his weather team, and then asks me when I’m going to find my own mare.” He bent over and took a nip at the scruff of Gleaming’s neck, and it took all of Gleaming’s efforts to stay steady on her knees. “Butterscotch knows, though. You’ve met him. He’s a very nice guy, takes care of much of Ponyville’s local fauna, wouldn’t hurt a fly. It’s incredibly difficult to rouse him to anger.”

“Butterscotch knows?” Gleaming asked, feeling her stomach sink. Relations between siblings wasn’t illegal, but it was certainly uncommon, and she and Dusk had been keeping theirs a secret. Even if Princess Celestia had found about it.

“Of course. Like I said, it’s difficult for him to get angry, but it just so happens Butterscotch has a sister, who’s a lazy pony if I ever saw one,” Dusk said, getting closer and closer to his sister until he was whispering right into Gleaming’s ear. “For months Butterscotch begged, pleaded, and wheedled his sister to put some effort into studying and working and failed. Then he found she was addicted to his cock and a good bucking by her brother, and he made a deal with her. Work hard and I’ll screw you again, slack off and I won’t.”

“O-oh?” Gleaming asked, feeling awkward now that she was the one doing the squirming instead of her brother. The heat of his breath on her neck was so enticing.

“Yeah, and now she’s making really good money as a mane-stylist, but Butterscotch is hoping she moves on to even bigger, more ambitious things,” said Dusk, before he suddenly pulled away from Gleaming Shield.

“Is something the matter, Dusky?” She asked.

“This, all of this,” said Dusk. “I’m not against continuing this, Gleamy, but we need to redefine it first. I’m a Prince now, and you’re Captain of the Royal Guard. We started this long before either of us graduated, but now maybe we should talk a little bit about this first.”

“About what?” Gleaming Shield asked again, feeling a little bit nervous.

“Like where we live, for that matter,” Dusk said, beginning to pace back and forth in his room. He had even more room than his old quarters in the side tower wing, so there was lots of space for Dusk Shine to work himself up into a frenzy. “I live in Ponyville, and you’re the Captain of the Royal Guard in Canterlot. I’ve met so many good friends in Ponyville, and I don’t want to leave them. I don’t expect them to follow after me to Canterlot, either.”

“I don’t think Princess Celestia would have an issue reassigning me to be your ‘guard’ if I asked,” Gleaming said, remembering her chat with the solar deity in the hallway.

“What makes you so certain of that?” Dusk asked.

Gleaming thought about it, but decided Dusk should know about it sooner than later. “I met her earlier, while on rounds. She said a few things that strongly implied she knew we had sex on a regular basis before you moved to Ponyville,” she said, her cheeks heating up as she recalled Celestia’s insinuations.

Dusk had a proper look of horror on his face. “And what the Princess implies, she basically already knows. No wonder she always looked so amused when I returned to the palace after the weekend.”

The two shared a collective shudder as they imagined Princess Celestia playing her benign matchmaking games.

Gleaming wondered how to tell her brother about the rest of her conversation with the Princess, only for her thoughts to be interrupted by her brother.

“You know,” Dusk said. “The Princess told me I need to get used to my new rank. She said she’ll help me, but that I need to start getting familiar with command. And, you know, as a Prince, I now outrank you.”

“Oh?” Gleaming asked. That was true, but the mare wasn’t sure what her brother was gett-

“Down,” Dusk ordered.

She didn’t even have time to consciously process it before Gleaming already found herself sitting down. She blushed. As Captain of the Royal Guard, she was the one used to giving commands, and yet she had folded at one word from her younger brother.

“That’s a good girl,” Dusk praised, walking over from the window to his sister. “Now, turn over, onto your back.”

Gleaming felt her face getting even hotter, but did as she was told, exposing her belly to the ceiling. She had her front and back legs pressed together, holding them up above her barrel.

“Lay your limbs out,” Dusk said, before adding, “And lay your tail down too. No hiding today, Gleamy.”

The mare complied, feeling her stomach roil with a hot heat that demanded to be quenched. Already, she could feel herself getting wet, and Gleaming Shield wanted nothing more than to be fucked hard before leaving this room.

“Good, good, just what I like to see in a subordinate,” Dusk said. Walking around to Gleaming’s head side, he suddenly trotted over her, carefully placing his hooves so he stood over her sprawled-out body. Bending his head over, Dusk sniffed at her mare bits. “Wow, you’ve really missed me, didn’t you?

Gleaming Shield gulped. Her brother had done that on purpose. There was no way he could have done it by accident. Dusk was shaking his back side every so slightly, but the slight jiggle of his rear end translated to his long, black stallionhood swinging back and forth. As it continued to dangle past his ballsack, Gleaming found herself thirsty for her brother’s horsecock.

“Do you like what you see? I haven’t had time to measure it since I ascended, and I’m not that narcissistic anyways,” Dusk commented. Yes, he knew what he was doing.

“It-it’s lovely,” Gleaming stammered. She had already memorised the details of her brother’s length before, but it was always hypnotic to see it in the flesh again. Gleaming would admit she had a problem when her blue eyes could lose herself in the sight of Dusk’s one-eyed snake for several minutes.

“Suck,” the new prince ordered, lowering his rear enough that his cockhead pressed at Gleaming’s lips.

Gleaming opened her lips, accepting the stallionhood into her mouth as she had done so many times before. Her first thoughts were that Dusk had clearly just showered earlier. Well, she would fix that problem, and make him smell like a stallion again.

The mare worked with gusto, working her tongue into a frenzy. Gleaming was hungry, but to get to the main course, she would have to work through the appetiser first. She swirled her tongue around his cockhead, pursing her lips and blowing gently on it, hoping to stimulate it further.

Dusk trembled above her, his tail sweeping back and forth in agitation. “Oh, oh fuck, you’re soooo good, Gleamy,” he said, having a difficult time staying on his hooves. “How could I...I know!”

Gleaming Shield paused, unsure what her brother was talking about. Then she felt it. Her lower body spasmed as she felt the walls of her pussy suddenly being scraped. Instinctively, Gleaming crossed her legs, shutting access to her crotch.

“That won’t do you any good,” said Dusk, the glowing of his horn now obvious. “I wish I thought about this before. Leave it to trashy romance novels to come up with something better.”

The mare would have made a comment, but Gleaming still had her mouth full with her brother’s stallionhood. The application of telekinesis to her inner walls was an awkward situation, nothing like being stuffed with Dusk’s cock, almost ticklish, but still a physical stimulation to which her mare parts were reacting. Even as she continued to lick and suck fanatically, trying to get the multiple cumshots she desperately wanted, Gleaming couldn’t ignore the reaction in her lower body. Were her mouth not occupied, Gleaming would be biting her lip hard down now to quell a moan.

But she was sucking on her brother’s cock right now, and so the moan went unabated. “Oh fuck, sis, that’s good,” Dusk grunted as he felt the vibrations from her moan. He could feel his peak coming on, but ignored it in favour of continuing to prod at his sister’s pussy, fully relying on his mind’s eye for his magic now that Gleaming had crossed her legs.

Gleaming squeezed her eyes shut, trying to cut off as many senses as possible as she trembled under Dusk’s magic. She could feel his magic. It was an acute sensation, tracing around her inner walls, going almost down to her cervix, where Gleaming nearly melted, unused to stimulation that far deep, before the touch reversed directions, coming back towards her entrance and then suddenly stroking her vulvar folds. It was all Gleaming could do to hang on, knowing the longer she prolonged her orgasm the stronger it would be.

Then Dusk pinched her clitoris.

Gleaming Shield shuddered, and her pussy went off like a dam as she came harder than she could ever remember. She blanked out for several seconds, the wall of pressure washing over her, sweeping her up in its tide, threatening to drown her under a tide of euphoria.

She vaguely tasted the sticky, slightly sweet taste of cum in her mouth, but was still unable to process anything other than the pure sensation that filled her body with joy and pleasure.

Then the tide washed out, and Gleaming found herself laying down, the floor her own personal beachfront. Finding herself starved for oxygen, she breathed through her nose rapidly. It was only then that she was able to finally swallow all of her brother’s seed. Gleaming blinked as she did. Either Dusk Shine was really pent up, or her brother’s virility had grown with his ascension. She couldn’t be certain, but Gleaming thought that might have been the most amount of cum her brother had ever ejaculated at once.

“Whoo-ee, your mouth is still as good as ever,” Dusk said, raising himself out of Gleaming’s mouth before he flopped down on the ground beside her, with his head next to her lower legs. Briefly shifting his limbs, he made sure his still-erect cock flopped over onto Gleaming’s neck. “So, what did you think, Gleamy?”

“I think,” Gleaming said, haltingly, before taking a few seconds to recollect herself, “I think I’ll have to wash up here before I head out. Anypony will be able to smell this.” Craning her head up, she looked down to her lower body. Her back legs, crossed over and squeezed tighter than ever, were drenched in her mare fluids.

“Oh, but that’s no fun,” teased Dusk. “You should go out as is. I’m sure your guards will wonder who you’ve been with, but the smell of a mare will certainly get the stallions alert and active again.”

“Dusk!” Gleaming said, scandalised, feeling her face burning again. “I-I have decorum to follow, there’s no way I could do that.”

“Oh, really?” Dusk asked, and then he growled in such a baritone voice that Gleaming found her pussy twitching again, even after having just cum. “Like coming up to your brother’s room to suck him off even while you’re working?”

“I-I was finished up work for the day,” Gleaming said, attempting to defend herself.

“Relax, sis, I’m only teasing you. Even if I do find the idea of you walking around smelling of sex really hot.”

“Du-Dusk!” Gleaming said, repeating her brother’s name for the second time in as many minutes. Why does everypony seem to be teasing me today?!

Dusk snorted. “That’s what happens when I move to a small town where the library has a whole section for romance novels, and ponies actually borrow them.”

Gleaming said nothing. Her brother’s stallionhood suddenly became a fascinating thing to look at again, much like Princess Celestia’s mane earlier.

“So, want to break in the bed?”

That was something more to Gleaming’s liking. “Of course,” she said, enviously eying the large bed. Even on her Captain’s salary, she wasn’t certain she would be able to afford something as comfortable as Dusk’s new royal bed looked, complete with the silken sheets laid over top.

“That’s good. I wonder what the maids' reaction will be when they clean up later. They'll probably have a pool of who I was with, no doubt,” Dusk said, picking himself up before his tone suddenly took a shift for the serious again. “Up on the bed, tail up, plot towards me.”

“Eep!” Gleaming let out a squeak at the sudden forceful command, but complied, quickly getting up onto her hooves and moving onto the bed, leaving enough room for her brother. As she suspected, the bed was unbelievably soft, and the texture of the blankets, even under her hooves, was simply to die for.

She felt a sudden tug of her tail, pulling the rest of her rear up slightly with it. Gleaming had not been fond of the tail tugging at first, but over time she had come to love it, and insisted on Dusk doing it to her. Something about the sensation of her tail being tugged just tickled Gleaming Shield in a way that made her all the more needy for a thick cock stuffed up her nethers.

Dusk climbed up onto the bed behind her. Even their combined weight wasn’t enough to make the bed frame shift. Gleaming didn’t have time to sigh in relief before her brother was suddenly on top of her, the weight of the top half of his body pressing her against the bed.

Gleaming Shield felt herself growing giddy. Her brother had grown both in height and weight with his wings and, if his earlier performance was any indicator, his virility as well. For the mare to be pinned down by her physically much-larger brother was a fetish she had been slow in realising she had, but one that was now acutely being satisfied.

“I see my big sister really got little lately,” Dusk said, whispering into her ear, and then Gleaming’s fetish went into overdrive. “She’s so tiny and small and meek now, she’s more like a little filly than a mare. I’m the big bad wolf now, and I’m going to establish dominance over my little slut.”

She groaned, wiggling her rump against Dusk’s cock. “Y-yes, that’s it, I love that,” Gleaming said, praising her brother. “Since when did you get so good at dirty talk?”

Dusk shifted himself, until the flare of his cock was pressing against her pussy, willing her lower lips to spread as easily as her upper lids had earlier. “My fashion friend recommended me a few books,” he admitted.

Gleaming chuckled. “Always the bibliophile, weren’t you Du-ooph,” she let out a grunt as Dusk finally entered her. The positioning was awkward, laying down on the bed instead of being up on at least her back hooves, but Gleaming could make it work.

“And now, just to cast this spell,” Dusk mumbled mostly to himself.

“Dusky, wait!” Gleaming said suddenly.

“Hmm? What?”

She bit her lip. Dusk had been right earlier. Now that he was a Prince and she was Captain of the Royal Guard, things had changed. There had been a fantasy Gleaming Shield had entertained for the last few years, never quite daring to make it a reality as she had advanced through the ranks of the military, not wishing her career to be cut short.

If she went through with it, she might be able to keep her career still, just as the Captain of the Royal Guard for a different alicorn instead, and with lots of leaves. It would require coming out to lots of people, including Gleaming’s parents.

Most of all, it would mean revealing her desires to Dusk Shine.

“Do you remember the roleplay scenarios we had when we were younger?” Gleaming asked, deciding to do this for once and for all. “Specifically, the ones where you would threaten to impregnate me?”

“Yeah, we did that more than a few times, those were some of the hotter ones in my opinion,” said Dusk. “Why, do you want to do a scenario like that again?”

“Not quite,” Gleaming said, getting more nervous with every word she spoke. “Impregnation, but not roleplay. I want your foals, Dusky.”

Dusk went as still as a statue.

Gleaming let him be. She had no doubt that that was an enormous revelation to suddenly take in.

The stallion was slow to recover, his rigid form slowly becoming limp, until suddenly he blinked and asked, “You want to carry my children?”

She nodded her head. The way Dusk had said those words wasn’t erotic, but nor did he sound confused. Instead, her brother’s words were full of intimacy, a needy desire that had just been awoken.

“Since when?” Dusk Shine continued to ask.

“It started way before you or I graduated,” Gleaming admitted. “When we were doing impregnation scenarios, perhaps even the first time we roleplayed it. I at first thought nothing much of it, but after you filled me up, I got up, and felt all your warm cum floating around inside me,” she said, describing it as vividly as she could. “It got me all hot and bothered again, and yet even knowing the contraception spell was active, I got to thinking, what if it wasn’t? I thought of one of them taking and getting me pregnant, and me carrying your foal.”

Then she added, "Princess Celestia, when she talked to me earlier, she hinted at that as well. She said she wouldn't mind us being together, and insisted on being able to foalsit."

Dusk was silent for a few minutes. At last, he said, “You really are my mare, aren’t you?”

“Oh yes,” Gleaming said, bobbing her head enthusiastically.

The stallion took a few more minutes, before he said, “Three nights from now.”

“Huh? What’s happening then?”

“Three nights from now, we’re having dinner over at mom and dad’s, all of us, along with the princesses, including Cadance and Blueblood,” Dusk explained. “Gleamy, I don’t actually know a conception spell, which this early on in season you’ll need to ensure pregnancy. I’ll need a few hours to find and learn one in the library. But,” he growled, nipping at Gleaming’s neck, asserting his dominance again. “But, when I do claim you, I want it to be where it all started. On your bed at mom and dad’s place.”

Gleaming’s eyes flew open. She hadn’t even thought of something like that. Her brother truly had grown up.

“It’s on your bed where I’ll take you, and it’s on your bed where I’ll plant a foal in you,” Dusk growled again, suddenly plunging much deeper into Gleaming all at once.

The mare yelped, surprised at the sudden intrusion, panting as Dusk began to pull out and then thrust back in again. “But you must realise something, little sis,” he said, having figured out that was a good button to push, and was delighted at the moan he got in return. “Mom and dad stopped at me for financial reasons, but I’m a Prince, I don’t have that limitation. I see a needy pony begging to be the mother of my foals, and I’m going to use it. We’re not going to stop at one or two foals, Gleamy. We’re not even going to stop at three or four or five.”

Gleaming Shield squealed into a pillow that she had grabbed, squeezing onto it for dear life as Dusk Shine filled her just right, his increased virility stuffing her more than she ever had in life.

“Your teats I sometimes tease and poke and even occasionally bite? They’re not going to be tiny anymore. They’re going to expand and fill out so you can nurse all the foals you’re going to carry for me, Gleamy. I wouldn’t get too used to your current armour. I don’t think you’ll be fitting into it again for at least another decade.”

Good heavens, Gleaming thought as Dusk exited and then entered her again, picking up his pace until he was pistoning his thrusts at a regular pitch. He’s serious, isn’t he? Ten foals, at least! The thought scared her. It terrified her, it left her feeling apprehensive…

...It excited her.

“You might strut around as the Captain of the Royal Guard in public,” Dusk hissed. “But everyone will really know you’re my needy broodmare slut, carrying Prince Dusk’s foals and single-hoofedly populating Equestria with new alicorns.”

Gleaming would have asked how he was so confident their offspring would be alicorns, but she was too in the moment. “Y-yes, yes, YES!” She screamed, and erupted, her mare juice gushing out as she trembled in the throes of her orgasm, barely able to function as a thinking individual.

“Then take it, Gleamy, take it all!” Dusk said back to her as he pulled out until only his flare was inside her pussy, then thrust in completely in one full movement, burying his stallionhood until his balls slapped up against her pussy. His cock throbbed like a beast of its own, and Gleaming Shield surrendered her sovereignty as an independent mare to her brother as it shot out an enormous dollop of seed, the cum no doubt coating her inner walls.

Then Dusk’s cock twitched again, sending out yet another load of baby-making batter, and then another, and yet still another, and Gleaming felt she could die happy as her pussy was filled to the brim and overflowing with her brother’s seed. With how much he had just unloaded, there was no doubt she would be pregnant in three nights’ time.

The two ponies sat there on the bed, basking in the afterglow of their sex, each feeling warm and content about the revelations that had been made and their future.

Then Dusk leaned in again, and whispered to Gleaming Shield, “These are your last three nights as a free mare, Gleamy. Enjoy them, because after that you’re mine.”

Gleaming shivered in trepidation, her pussy still winking even now. She was so sensitive, she was certain she would orgasm again if Dusk even shifted slightly. “I wish we were having dinner at mom and dad’s tonight already.”
