In Which Princess Celestia Teases Gleaming Shield

Dusk was deified.

Gleaming Shield didn’t know the circumstances, outside of it having something to do with Dusk Shine’s stallion friends in Ponyville and a spell, but the outcome was undeniable. There stood her own little brother on the podium, with wings. But he wasn’t quite her little brother anymore. Even before he had left to Ponyville, Dusk was already taller than Gleaming herself. Now, he seemed to have added a few inches to his withers.

She took a brief chance to look around the ceremonial hall. It was only the second event in a year that Gleaming Shield had delegated most of her duties as Captain of Canterlot’s Royal Guard, coming after the wedding between Princess Cadance and Prince Blueblood, in which Gleaming had served as one of the bridesmaids for her childhood friend.

Speaking of those two, Gleaming took a side glance at the happy couple, standing next to her. While they both seemed in good spirits, it was clear from their baggy eyes and overdone grooming that rulership over a sovereign state a thousand years out of history was exhausting.

As Princess Celestia began to talk again, announcing Dusk Shine’s new status as Prince, Gleaming Shield paused. Did that mean she was a Princess then, now that Dusk was crowned the newest Alicorn monarch of the realm? She was certain to receive a title at least, even if it was perhaps something like Duchess or Marchioness instead. Gleaming wondered how her role as Captain of the Royal Guard would play in there as well.

Princess Celestia called for applause, and even as she cheered, Gleaming Shield suddenly let out a hiss. Thankfully, it was lost in the stomping of hooves and wild hollers. It occurred to Gleaming that after Princess Cadance had ascended, she had soon started dating Prince Blueblood, and she was now connected to the royal family by marriage instead of merely adoption.

The only two unwed females in the royal family were Princesses Celestia and Luna.

Even as her heart and hooves went out to her brother and his successes, Gleaming Shield started thinking. It had been so long since she had seen her brother for more than a couple of days at a time, not since Dusk Shine had left to Ponyville. She didn’t know if the chemistry could still be there between him and her, but Gleaming decided she would have to check. If it was, she would need to move in before any other mare could snag him, even if they happened to be the royal diarchs who raised and lowered the sun and moon.

One day later, after shaking off the hangover from the alcohol she had been easily plied with by family members and friends alike, Gleaming Shield had returned to work. After chewing out her subordinate for all the minute flaws she had seen in security during the wedding, the white-coated mare decided to take a patrol around the castle. There was nothing like seeing their captain walking around and doing inspection to keep the guards alert on their hooves.

If her patrol happened to take her by her brother’s room, well, so much the better for Gleaming Shield.

Donning her half-armour, Gleaming started at the training grounds, smiling as the new recruits squirmed under her gaze, before giving them a nod of approval. From there, she wandered around the barracks and to the mess, making sure nopony got any ideas about sneaking in unauthorised contraband. Afterwards, she briefly stopped in at the royal treasury, making certain its defenses against most conventional threats were still up to snuff (Discord was another thing entirely), before her path finally took her up several floors to where Dusk’s quarters were located.

Then Gleaming stopped as soon as she cleared the stairs.

“Oh, hello, Gleaming Shield,” said Princess Celestia, her smile as warm as the midday sun itself.

Gleaming skidded to a stop, and dropped down in a bow. “Princess Celestia,” she greeted the Princess back.

“Now, now, there’s no need to be like that anymore,” said the other white-coated mare, continuing to smile. “Cadance’s parents received the title of Duke and Duchess, but they were her adoptive parents. We still haven’t decided what your parents and you shall receive, but from one Princess to potentially another, you need not be so formal in private anymore.”

Gleaming Shield raised an eyebrow. “Oh? Truly? I would have only expected as high as a Duchess.”

“Well, like I said, we still haven’t decided yet. It’s up to Luna and I alone, but we are still receiving input from a few historians,” Princess Celestia said, before her smile suddenly took a turn for the mischievous. Craning her head down, the Princess shuffled beside Gleaming Shield so she was pressed in right next to the smaller pony. “Of course, if you move fast enough and Dusk is receptive, you would be a Princess anyways.”

It took a couple of seconds for Gleaming to realise what the Princess meant, but when she did, she nearly cleared the floor, jumping up in surprise as her hackles rose in reflex. “P-princess-I, I can explain!” Gleaming stammered.

“Oh, there’s no need to explain,” Celestia coyly said, moving away from Gleaming. “Even though Dusk tried, he could never quite clean off the smell of sex entirely. It took a little bit longer to figure out who he was with, but since he was always so shy to making new friends, there was logically only one mare he could’ve been with.”

“P-p-p-please, Princess,” Gleaming begged. She couldn’t even look Celestia in the eye anymore. Instead, she found Celestia’s multi-coloured, flowing mane suddenly fascinating.

“Ah, I can see why he would like you, you certainly look so cute when you’re flustered,” Celestia continued to tease her. “Your parents raised two fine foals, one who became my student and eventually the newest Alicorn Prince, and another who became Captain of my Royal Guard at a young age. I look forward to seeing what your own coupling brings.”

Gleaming Shield was sure she must have resembled a tomato at that moment.

The Princess continued, no doubt aware of just how much her Captain was squirming. "Your parents no doubt will want first dibs on foalsitting, but Luna and I wouldn't mind, either. Now that my niece and nephew are in the Crystal Empire, it's less likely I'll be hearing the pitter-patters of their own foals, so you two will have to give this pony some hope."

Gleaming felt like finding a corner to go and curl up and die in from how embarrassed she was.

“Ah, but I should stop, you are my Captain, and it wouldn’t do if you’re so flummoxed when you meet Dusk,” Celestia said. “In any case, take care. I’ll keep Cadance and Blueblood busy and too distracted from coming up to talk to Dusk.”

With that, the elder mare strode away, walking back down the stairs.

Gleaming rushed for the nearest mirror, just about hyperventilating. Using the breathing exercises that were ingrained in her very being, she steadily got her body under control, moderating her heartbeat.

She knew! Gleaming thought to herself, trying to will away the red blush in her cheeks. She knows! She knows Dusk and I have sex like, well like I was always in season!

Then Gleaming Shield corrected the present tense in her thoughts for a past tense. Ever since Dusk Shine had left to Ponyville, Gleaming had found herself needy, unwilling to accept any other stallion but for Dusk. She had only seen him a hoofful of times in the last year, with only barely enough time during each reunion for a brief fling. This was quite possibly the most amount of time Gleaming would be able to spend with Dusk since the wedding, alone.

She would use it productively, Gleaming decided.

Sastisfied that her face was no longer red with embarrassment, Gleaming trotted down the hall. Putting a hoof up, she knocked on the door to her brother’s new royal quarters.

“Who is it?” Dusk asked, his masculine voice clear even through the thick doors.

“It’s me, Gleaming Shield, Captain of the Royal Guard,” said Gleaming.

There was no hesitation as Dusk Shine said, “Come in.”

Taking a look to both ends of the hallway to see if there was anypony else around, Gleaming pushed the doors open, entering Dusk’s room.

In Which Dusk Shine Teases Gleaming Shield

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.”

In Which Princess Cadance Teases Gleaming Shield

“Perhaps I should look into investing some of my bits,” Gleaming Shield said. “Which company has stationary manufacturing as part of its portfolio?”

Sarcasm wasn’t something Gleaming Shield often employed, but she believed it to be a better method than outright contempt for the paperwork that occupied her desk. Were the enemy to invade right now, they would be unable to capture her. All Gleaming needed to do was hide behind the impenetrable wall of papers.

“You could just let me do some of it, you know,” offered her secretary, a pegasus by the name of Westwind.

Gleaming scoffed. “Yes, I could, but then some bureaucrat would recognise your writing and reject everything in this pile, even the stuff I did. Or you’d get some self-pretentious supremacist prick who insists she can’t read wingwriting because, well, 'because', and then I’d have to redo it all by myself.”

Westwind was quiet for a few seconds, contemplating, before he said, “Wouldn’t it be better to have a unicorn secretary instead of me, then?”

“No, not at all,” Gleaming insisted. “You’re the best logistics pony I’ve ever had. I swear to Celestia sometimes the Guard would fall apart within three days without you over some minor quibble, like not enough oats in their morning meals, or their new horseshoes not being the right size.”

“I wonder if that’s supposed to be a vote of confidence in me, or a vote of no-confidence in everypony else,” said Westwind.

“It’s a vote for you,” said Gleaming, reassuring him. Given Gleaming Shield was planning on leaving Canterlot soon to move to Ponyville, she needed a stable roster of ponies to support her vice-captain when he inevitably became captain of the Royal Guard in Canterlot. While her vice-captain wasn’t quite as good at the administrative side of the job as Gleaming herself was, with ponies like Westwind around she wasn’t too worried.

Idly, Gleaming Shield took a glance at the clock. Lunchtime was coming up. More importantly, there was only forty hours until the Sword of Damarecles came down on her, only Gleaming was looking forward to it, and she would never describe her brother’s cock as a ‘sword’. A spear maybe, but not a sword.

Oh Princesses she was hungry, and it wasn’t for regular food.

There was a knock on the door. “Come in,” Gleaming Shield called out.

The door opened, and in stepped Princess Cadance. “Is this a good time, Gleaming Shield?” The pink-coated mare asked. “I wanted to discuss a few things about dinner tomorrow night.”

Gleaming took a look at the clock again, before directing her attention to her pegasus secretary. “Westwind, go take your lunch break now,” she ordered. “Princess Cadance and I have some things to talk about, preferably privately.”

“Yes, Captain,” said Westwind. He gave her little fuss, only taking several seconds to clean up his desk before he trotted out of the office, closing the door behind him.

As soon as he was gone, Cadance immediately turned around, and her and Gleaming Shield suddenly dropped to the floor.

“Sunshine, sunshine, ladybugs awake, clap your hooves and do a little shake,” said each mare as they went through an odd routine of peeking out from behind their hooves, following by bumping their hooves and then shaking their rear ends at one another.

Gleaming let out a little giggle. “Even now we still do this song and dance routine.”

“Well, it wasn’t for nothing I made you one of my bridesmaids,” Cadance said in agreement.

The captain let out a contented sigh as she remembered the fonder parts of that day, deftly choosing to ignore the other parts of the wedding between Prince and Princess. Then her eyes refocused past Cadance to see the paperwork back on her desk. “I’m going to take an educated guess and say you’ve got more paperwork than I do.”

Cadance followed Gleaming’s glance and huffed as she saw the pile of paperwork. “Something like that. Fortunately, Bluey does the lion’s share of the paperwork. It wasn’t just good looks I married him for. If I didn’t have him, I’m certain I would have borrowed Dusk away from Ponyville to spend a week or three getting through it.”

Gleaming Shield giggled again at that. During the time Cadance had been Dusk’s babysitter, Gleaming and Cadance had gotten to know one another well. Each was quite familiar with Dusk Shine’s quirks, such as his love of organisation. Bringing the Crystal Empire into the modern age would have been something he either fell in love with or the task that would finally turn him off of paperwork for good.

“I’m sure he’ll make his way down there again, if only for the books,” said Gleaming.

“Yes, perhaps. I’m a little bit envious of you, though,” said Cadance.

“Oh? Why is that?” Gleaming Shield asked.

“Well, once you move to Ponyville, Dusk will no doubt take care of most of your paperwork for you, so you can actually go out and about most hours of the day.”

“Wait, what?” Gleaming asked, her thoughts suddenly coming to a halt. “Why would you think I would be moving to Ponyville?”

Cadance rolled her eyes. “Oh, please. I’ve seen the way you two looked at one another yesterday at functions. It’s obvious you two are far more than brother and sister. Well, that, and Auntie isn’t quite as subtle with her hints as she thinks she is. So, tell me the details, Gleamy,” Cadance said, suddenly breathless with anticipation.

Gleaming Shield reddened. “I’m not telling you!” She insisted.

“Oh, why is that? Don’t be shy, I won’t blab to anyone, not even Bluey,” Cadance promised. “So what’s the scoop, girl? How did it start? Were you each in a hurry one day and only had one shower, and had to share? Did you literally run into him and fall head-over-plot? Was it a slow-burning thing where you slowly realised you loved each other, like loved-loved?”

“Cady!” Gleaming squealed.

“And what about when the two of you get into bed?” Cadance continued, either oblivious to or ignoring Gleaming Shield’s rising embarrassment. “Does he caress you gently like a gentlestallion, whispering sweet couplets into your ear? Or do you like it a little bit rougher as he pounces on you and makes your knees buckle with how good it feels? Or perhaps it’s the other way around, where you dominate him.”

“Cadance, stop, please, stop!” Gleaming Shield pleaded.

“Aww.” Cadance pouted. “Auntie mentioned what she did before. I’m sorry, Gleamy, you just looked so cute there, I couldn’t resist. You have the most adorable squeak, you know.”

“Yes, and I prefer only Dusk hears that,” Gleaming snapped back, only for her eyes to bulge as she realised what she had said. Gleaming slapped her hoof up in front of her mouth, but the damage had been done.

She would swear Princess Cadance had some feline ancestry, the way the pink-coated pony suddenly looked like the Coltshire Cat. Gleaming swallowed. Cadance had her dead to rights if the other pony wanted to resume her teasing again.

“Oh, relax. I already got my entertainment for today,” Cadance said, letting out a hearty laugh for several seconds. “In truth, I just came to check that you were going to be able to come to dinner at your parents’ place tomorrow night.”

“I will, if I can ever get through this pile of paperwork,” Gleaming Shield groused.

“And if you ask Dusk to help, you’ll end up getting distracted and fall even farther behind,” Cadance said.

“Yes, quite possibly. Don’t worry, I’m sure you’ll hear all about it soon, since something Dusk and I thought was secret obviously wasn’t,” Gleaming said in a deadpan tone. Tease me once, fool on me. Tease me twice, still fool on me. Well Cadance, you won’t get to tease me again, I’ve had enough of this! Having been reduced to an embarrassed wreck for the third time in three days, Gleaming was certain she was inured to it.

“So, have you talked about foals yet?” Cadance asked, attempting to keep the subject on something she did indeed want to hear more about. "Me and Bluey would like to try for one soon, just as soon as things get settled down a little up north."

“Briefly,” Gleaming acknowledged, sparing the more savory details. “Dusk did mention that if, no, when we did have foals, they would be alicorns. Is that certain?”

“Yes,” Cadance confirmed. “Auntie mentioned the same thing. Her and Luna had foals thousands of years ago, but having to bury their children who eventually died of old age depressed them so much the two have had periods of either celibacy or lots of contraception.”

“Oh.” Gleaming sucked in a deep breath of air. Cadance had managed to do a good job of killing the mood in the room, along with just a little bit too much information about the older Princesses’ sexual exploits.

“So when you and I have foals, they’ll all be alicorns. I’m sure we can even babysit one another’s foals, so long as they’re not too rambunctious. Of course, I’m sure you’ll have plenty of time in Ponyville, once Dusk decides to do all your paperwork and you nurse your many, many foals,” Cadance added in a teasing manner. “Just make sure not to have too many, I wouldn’t want to feel like we’re having a reproduction arms race between Ponyville and the Crystal Empire, even if you do love your brother very deeply.”

“Cadance!” Gleaming whimpered. Unable to take it anymore, she quickly moved behind the desk, huddling underneath the piles of paper that surrounded her on every which side.

“Perhaps I overdid it?” Cadance asked herself. “Well, I can see why Dusk loves her, at least. She really is cute when she turns red like that.”

“Lalalah, not listening!” Gleaming said, though her voice was muffled.

In Which Twilight Velvet and Night Light Tease Gleaming Shield

It wasn’t every day that three Princesses and two Princes of the realm, along with a baby dragon supped together in the home of civilians. Of course, Gleaming Shield reminded herself, Mom and Dad aren’t quite civilians anymore. While nothing was official yet, it did appear that Gleaming herself would become a Princess of the Realm, and her parents a Duke and Duchess.

Duke Night Light and Duchess Twilight Velvet. No matter how many times Gleaming rolled the words over her mental tongue, they just sounded weird. Gleaming may have been a grown mare, able to make her own decisions, like choosing to join the Royal Guard or having a roll in the hay with her brother, but she still thought of them as mom and dad. Hopefully there would only be a few times in the next few years that she would be formally required to call them Duke and Duchess to their face.

Still, Gleaming Shield was rather happy. Though none of them were her work colleagues, all ponies present were ones she felt comfortable being around and talking to, the incessant teasing from a select few over the last few days notwithstanding. Given the paucity of Equestrian royalty who weren’t present at this supper, Gleaming had taken the opportunity to sweep the entire city block where her parent’s home was, getting the all-clear from the ponies she had deployed.

It also meant there should be no obstacles to the dicking she was due to receive tonight. It was all Gleaming could do not to wag her tail. Even for what this was supposed to be, a casual dinner, Gleaming still needed to maintain some level of decorum.

“It’s good to see you again, Night Light,” said Celestia. “I’ve been able to see your wife infrequently, but it’s been what, two years since we managed to chat?”

“About that time, yes. I believe it was at the Hearth’s Warming Eve play shortly before Dusk left to Ponyville,” said Night Light.

Though the dinner was in celebration of Dusk Shine, it was also a way to reconnect Night Light and Twilight Velvet with the Royal Family. The two sides had had limited interactions over the years, thanks to Cadance being Dusk Shine’s babysitter, Dusk later becoming Celestia’s student, and Gleaming Shield becoming Captain of the Royal Guard. However, they lacked more intimate moments, usually meeting in crowded places instead of in private. The dinner had been the perfect idea to become somewhat more familiar with one another.

“It is always good to see another pony with a Moon Cutie Mark!” Said Princess Luna. “How, pray tell, did you acquire it?”

You fool, you don’t know what you’ve done! Gleaming mentally shouted. She knew all too well once one got her father started on his Cutie Mark story, he simply did not shut up.

For once, however, Gleaming Shield was in good luck. Night Light had gotten his Cutie Mark, a symbol of the crescent moon, in astronomy, and Princess Luna was good at interjecting and asking more questions. In so doing, their conversation was actually far more interesting than previous tellings.

To Gleaming Shield’s right side, Twilight Velvet just rolled her eyes, having obviously heard the story more times than she could count. Judging that it was safe to start a second conversation at the table, she turned to her only daughter and asked, “So, how has work been the last few weeks, Gleaming?”

“It’s been mostly alright,” said Gleaming, not wanting to get too in-depth about the soul-sucking bugthing that was paperwork. “I was able to delegate lots of work to my vice, else I might have had to miss my own brother’s coronation.”

“Yes, just like you would have missed dinner if you had skipped out like you almost did on his graduation day.”

“And as I keep reminding you, there was an incident in the mess that day,” Gleaming said, gritting her teeth. Her mother would never let her live that down.

“Ah, was that the day of Custard’s Last Stand?” Celestia suddenly asked, having been listening in on the conversation between mother and daughter.

Gleaming Shield affirmed Celestia’s question with a nod of her heads. “It took them weeks to get all the custard cleaned off the walls. I still have nightmares of it in my fur,” she shuddered.

“Ohhh, right, I forgot that was when that happened,” said Twilight Velvet.

“Don’t worry too much,” Spike piped up from his spot at the end, where he could be seen by all and see all. “You’re not the only one in this family that that’s happened too.”

“Spike!” Dusk Shine hissed at him from beside him.

“Oh yes, how could I forget,” said Twilight Velvet, blissfully unaware of her son making a motion with his hoof, begging her to stop. “Dusk had a bad time with some cheese when he was melted, and I don’t believe he’s eaten a quesadilla ever since.”

“Moooom,” Dusk groaned, blushing as everypony else had a brief laugh at his expense. Even Cadance and Blueblood, who had been mostly silent throughout the dinner, were able to get in a chuckle.

“Oh, Dusk,” said Night Light, sensing his conversation with Luna was at an end. “It’s been rather overwhelming for us, our only son suddenly becoming an alicorn and a prince all at once. Your mother just wants some familiar ground to tread on, and for her, teasing you is one of those ways.”

“That’s right,” said Twilight Velvet.

“Oh, fine,” Dusk huffed, but didn’t push any harder than that.

Gleaming Shield wanted to gloat. At last, somepony other than her was being teased that week.

“Don’t think I don’t see that grin, Gleaming,” warned her mother. “I haven’t teased you in some time yet.”

The grin on Gleaming’s froze in a terrifying rictus.

“Both my children are grown up, but you’re the older one here by several years, yet you still haven’t brought a stallion home!” Twilight Velvet admonished her. “You need to get out a little more, and if you can’t, surely you can relax your self-imposed rules about dating within the workplace? I’ve met that secretary of yours, Westwing was it? Such a sweet young stallion.”

Gleaming didn’t even bother to correct her mother that it was Westwind, not Westwing. Her eyes found her father’s eyes. Help me, her eyes screamed.

Her father shook his head.

Traitor! Her eyes said, Traitor!

“Don’t tell me your poor old mother is never going to become a grandmare. Now that Dusk is a prince, it’ll be even more difficult for him to find a mare, now that everymare and her daughter is going to be throwing herself at him.”

“That’s, um, enough, mom,” Dusk said, interrupting Velvet before she could get into a right rant about foals. Gleaming was about to breathe a sigh of relief, before Dusk’s next words almost sent her into a nervous spasm. “Er, Gleamy, maybe we should tell mom and dad?”

Gleaming Shield swallowed, her mouth suddenly dry. The fine wine began to feel just a little bit nauseous in her stomach. Oh, right.

“Tell us? Tell us about what?” Night Light asked.

“Er...well, you see…” Gleaming tried to speak and failed, fumbling for words.

“We’re together,” Dusk said, doing what Gleaming could not. “Like, together, together. We were for a few years, drifted apart when I moved to Ponyville, but now we’ve decided to pursue it again, seriously.”

Silence. Gleaming could hear her own breath all too easily, and she felt like she needed a bag. Wasn’t Dusk supposed to be the one to go into nervous fits? It was as if their habits had switched around along with their relative sizes.

“Oh. Well, that’s disappointing,” was all Twilight Velvet had to say.

“Disappointing?” Asked Princess Celestia, the suddenly frosty tone in her voice hinting that the other mare should be careful with her next few words.

Thankfully for Twilight Velvet, her husband was quick to save her. “Not like that,” Night Light said. “Rather, it’s simple mathematics.”

“Mathematics?” Blueblood suddenly asked, his first real contribution to the conversation so far, even if it was a one-word question.

“Yes,” Night Light said, frantically nodding his head. “If our son and daughter married other ponies and had foals at the same time, then we could have two grandfoals within the year, then two more in the year after that, and so on, or at least Velvet likes to imagine. If Dusk and Gleaming marry each other, they can only have one offspring per year between the two of them, not two.”

“Ooooh,” said Blueblood and Cadance.

“Wait, what?” Gleaming asked, snapping back to reality. “That’s it? Not a word about the fact Dusk and I are in a relationship?”

“About that,” Night Light said rather haltingly, “We kind of, um...already knew.”

Twilight Velvet nodded. “A mother always knows.”

“What? But how?!” Gleaming and Dusk both asked at once.

Night Light rose a hoof and started tapping on the table as he listed off the reasons, “Well, you both always seemed to wash your sheets every time we were away for a day or later, we’d always find clumps of purple and white hair together whenever we had to clean out the bath drains, you weren’t as careful cleaning up the smell after, we stumbled across Gleaming’s toy collection once and Dusk’s magical aura was still on it, and you two weren’t anywhere near as subtle with your looks at one another as you thought you were.”

“Ah, that makes sense. I guess we weren’t as careful as we thought we would,” said Dusk.

Gleaming Shield had a different reaction to all their dirty laundry being aired, as she could feel her face burning as her father had continued. “Oh, come on!” She said, rising to her hooves. “Is there anypony here who didn’t know I was bucking my brother?!”

“I figured it out a long time ago,” Celestia offered, but Gleaming knew that already.

“I actually knew well before yesterday,” said Cadance.

“I have to make sure not to accidentally look into your dreams after the first raunchy dream I saw of yours,” Luna admitted.

“I didn’t realise it at first since I didn’t know what sex was at the time, but once I started reading on pony biology I put it together,” said Spike.

As one, everyone seemed to realise one pony hadn’t answered a yay or a nay yet, and turned to look at him.

Blueblood weakly raised his hoof. “I didn’t, but now I do...I guess,” he said.

“That’s IT!” Gleaming Shield shrieked. “I’ve had enough of this supper! All of you, carry on and forget about us. Dusk, you’re coming with me!” She said, lifting her brother up in her telekinetic grip.

“Gleamy, stop embarrassing us,” Dusk said, but he didn’t seem opposed to being carried away.

“Daughter, son, where are you going?” Twilight Velvet called out as Gleaming reached the stairs.

“You’re getting your grandfoal tonight, mom!” Gleaming shouted back as she started climbing up. “The first of many!”

“Unbelievable,” Gleaming groused, pacing as soon as she got into her bedroom. “What was that?”

“No, what was that?”

Gleaming shuddered, and her tail instinctively rose, exposing her flower. That wasn’t her brother Dusk Shine, the laid-back, friendly stallion she had grown up with. That was Dusk Shine, dominant alicorn prince who was about spread her wide. Annoying the latter one was not a smart decision to make.

“I was hoping to have a little bit longer chat with everypony else, but since you can’t seem to handle a little bit of teasing you decided to come up here right away,” Dusk said. “Well, now we’re up here.”

Gleaming mewed, dropping to her belly and crawling towards the underside of Dusk’s barrel.

“No, no oral tonight!” Dusk commanded. “I’m breeding you tonight, just as promised, and I’m not going to waste a single drop of my seed where it’ll do no good.”

Quickly, Dusk cast several spells, one that Gleaming recognised to soundproof the room, and one more to stop any vibrations from being transmitted as well, so the ponies downstairs couldn’t feel the bed rocking on the floor either. Then, he cast his horn, and Gleaming suddenly found herself on her bed.

“I really should learn teleportation someday,” Gleaming said, marvelling at her brother’s magical prowess.

“I don’t see what good it’ll do you,” Dusk said. “Teleportation isn’t recommended for pregnant mares, so that rules out at least the next decade or so.”

Gleaming shivered in anticipation at his words, being reminded of what Dusk had said about breeding her for at least a good ten foals.

“I don’t know precisely how this should feel, but this is the conception spell I promised,” Dusk said gently, and he cast another spell with his horn.

Gleaming felt the spell wash over her. It felt...different, from the normal contraception spell. Where that felt like a brief feeling of warmness washing over her body, this was different. Her whole body was suddenly hotter, and the feeling didn’t go away. More importantly, the heat was concentrated, in her abdomen and her loins.

Gleaming needed.

“Well, I did promise you I’d breed you tonight, but, well, tssk tssk,” Dusk said. Gleaming couldn’t see him, given Dusk had teleported her to face towards the wall on her bed, so she didn’t know what he was doing.

Suddenly, something poked at her mouth, and Gleaming opened her lips without thinking. She knew what it was a second later as a large ball fit into her mouth, soon being tied off behind her muzzle.

“Mmmfh, mmmfh!” Gleaming protested as she turned around to face her brother.

“Down!” Dusk ordered, and Gleaming stopped. “You brought this on yourself, Gleamy, the way you acted downstairs. Be a good girl and I’ll release that after,” he said, stressing the last word. Looking through Gleaming Shield’s toy collection, secreted away in a box with a magical lock that he of course knew how to open, he selected a few more items. “Given the circumstances, I think it only fitting you be bound tightly as I make you my mare.”

Gleaming’s heart thumped. His mare. She offered no resistance as Dusk used his magic again to push her front legs down so her rump was raised, and then as he spread her back limbs and held them in place with a spreader bar.

“Oh yes, and how could I forget this? That was a wild week, I think that’s when I truly began to realise how much of a submissive slut you were for your brother’s cock.”

Gleaming turned her head back around, and saw what Dusk Shine was talking about. Her eyes widened.

It was a silver collar, polished to a shine with a retractable end to easily slip in and out. Gleaming remembered how it had a magical lock for unicorns to roleplay with, making it difficult for the sub wearing the collar to slip out unless she knew how to unlock it. It had been around her neck on a few occasions.

What really sealed the deal for her was the tag that hung loose from the front, ‘Property of Dusk Shine’.

Gleaming started wagging her tail.

“Yes, yes, you enjoy that, don’t you, little sister?” Dusk asked as he levitated the collar in place over her neck. Using his hooves for once, Dusk fumbled as he turned it around, then closed in the retractable part.

Gleaming sighed in content as she heard the soft click of the lock, knowing she was just about completely helpless now, ready to be taken by her big brother.

“Now, what else? Ah, yes, your tail!” Dusk said, as he grabbed Gleaming’s tail, still wagging furiously, in his magical grip. Taking a thin rope out of the toy box, he restrained her tail with one end of the rope, then connected the other end of the rope to a clasp on the back side of her collar. The effect was that Gleaming’s tail was held in place connected by the rope to her collar.

More importantly, it left her dripping cunt completely open and exposed to her brother.

“Well, well, well,” said Dusk, hopping off the bed and pacing around. “It’s been some time since we started doing this, hasn’t it? We were both young then, much more immature and sexually inexperienced then. Of course, you used the opportunity to relentlessly tease me back then. Well, guess what, little sister? Now I’m the big one, and I’m the one who’ll be the one doing the teasing around here.”

Gleaming wiggled her rump in response. Just fuck me already! She thought furiously.

As if sensing her mental cry, Dusk Shine climbed back onto the bed, then climbed over top of Gleaming Shield so most of his weight pressed her down into the bed, being careful not to bend her tail. Were it not for a spell to give the bed extra strength, Dusk’s increased size was at risk of breaking it. “I’d like to say this is your last chance to back out, be a little bit chivalrous and all that, you know,” Dusk said, before leaning in closer to Gleaming, talking straight into her ear. “Of course, the truth is you’ve awakened a fire in me I didn’t know I had. I want you, sis, Gleamy. I want you, and your body. And I’m going to have it, I’m going to make you my mare. There’s no takebacks now.”

The mare’s heart thumped again, and for a few seconds, Gleaming Shield suddenly found herself nervous. Did she really want to go through with this? Once she started to carry and then bear Dusk’s first foal, she was set on a path from which it would be very difficult to turn back. Gleaming suddenly found herself nervous.

Then Dusk’s flare pressed up against her pussy, and all of her anxieties evaporated. Gleaming Shield had protected Canterlot for many years. Dusk, her big brother, would protect her in turn.

It was a slow, gradual process as Dusk’s stallionhood entered her, parting her vulvar folds. Gleaming could feel her inner walls being expanded and stuffed as they reshaped themselves to accommodate the larger presence of the meaty cock. Her pussy contracted, trying to pull Dusk in further and further. It was as if her lower lips knew that this was the time the large stallionhood would be siring a new foal further in, and refused to let it go.

“Oh, buck, you feel so good tonight sis,” Dusk said, letting out a pleasured groan. “All those exercises you do in the Guard keeping you nice and fit, and really tight down here too no doubt.”

“Mmm-hmm,” Gleaming agreed, nodding since her words were still muffled behind the ball gag.

“Of course, you won’t be staying in the Royal Guard, at least not in Canterlot,” Dusk said, having finally settled himself in a nice, cozy spot inserted deep inside of Gleaming Shield’s lower body, the two siblings connected hip to hip. “I remember some of those scenarios we roleplayed, before I left to Ponyville. Sometimes, I threatened to put a foal in you to get you kicked out of the Guard. Well, this time it’s for real.”

Gleaming Shield let out a moan as Dusk continued to talk. “You can come to Ponyville and give birth to my foals. Spike can be my assistant and clean-up, but you, you can be my cock warmer and mother of my foals. Every day, you’ll wake up and nurse them, feed them, and take them to school. Ponyville doesn’t need much of a Royal Guard, so you can spend most of that time behind a desk. My desk, specifically, where you’ll crawl to every day, lick my cock out of my sheath and kiss my flare, worship it as that which will give your foals while I do paperwork. You love my cum, don’t you, Gleamy?” Dusk hissed. “You love it in your mouth, you love it up your plothole, but most of all, you love it gushing deep inside your cunt, waiting to invade one of your eggs and make you my mare?”

The mare would have protested a little bit with a muffled moan, since she would go stir crazy without at least something intellectually stimulating. However, she was interrupted as Dusk Shine finally chose to shut up and pull out until his medial ring was almost out of her pussy, only to slam right back in.

“Mmmf!” Gleaming moaned into the gag, only to let out squeak of pleasure as Dusk quickly sped up. The friction from his flare and cock as he pulled out, only to slam back in each time was incredible! Whether it was the conception spell, her own need for a foal, or the increasing wetness she had felt as Dusk seduced her with her dirty talk, Gleaming simply didn’t care. All she wanted was more.

Gleaming felt her butt wiggle instinctively, moving every which way to afford Dusk’s stallionhood every last centimetre of space possible into her willing pussy. Gleaming could feel herself drooling past the ball gag, but didn’t care as the sensations in her cunt overpowered almost everything else. She closed her eyes. Looking into a pillow wasn’t nearly as stimulating as the heat roiling in her pussy, waiting to be let out.

“Then take my cum, Gleaming!” Dusk said, pulling out again and slamming right back into her, his balls smacking up against her lower lips as his length entered as far as it could get into his sister. “Take it all, and get pregnant! Bear my foal!” He growled, pulling out and then pounding back into Gleaming Shield again.

“Mmf!” Gleaming moaned even louder into her gag. She was beginning to tremble as her body hit new highs in how many nerves could scream out in joy, and yet Dusk still kept moving, thrusting in and out of her.

Then he wrapped his front limbs around her neck in the motion of a protector.

Gleaming came, and it was all she could do not to black out at the pleasure.

She shivered as her pussy quivered, squirting out a dollop of marecum. Even with Dusk’s cock plugging up her marehood, Gleaming could still feel her back legs getting wet as fluid dripped down, drenching her fur.

And yet Dusk still kept moving, plunging in back and forth in a perpetual motion, showing no sign of stopping even as he squeezed Gleaming tighter and tighter, and she squeezed his stallionhood tighter and tighter. Gleaming felt herself floating, or at least that was what it had to be, as her hooves couldn’t have been touching the bed anymore. She began to feel light-headed, all the blood in her body moving down to her rump, where that accursed fire and the ever-insatiable itch were at least beginning to feel satiated.

Then Dusk moved out just a little bit too far, his medial ring at last existing her pussy, before plunging back inside. In the process, it made a hard bump against Gleaming’s clitoris, and the mare gasped as another orgasm went off. This time, she was even more sensitive than the last. The pleasure sent her to an exalted land of nirvana, one which Gleaming wasn’t sure she ever wished to leave. Even through her closed eyes, she could still see stars.

But then Dusk’s stallionhood twitched, and Gleaming Shield felt relieved as it shot out seed, wetting her inner walls that felt dry with heat, and then again and again, until it felt as if there wasn’t a single empty spot in her pussy, being taken up either by cum or cock.

Gleaming Shield sagged, feeling happy. The warm cum pooled deep inside her pussy must surely have entered her womb. While she knew better about biology, she liked to imagine that within the hour some embryo would already be implanted on her womb wall, beginning to divide and multiply.

Except Dusk didn’t stop. Even though he had cum once, the stallion kept moving.

“Mmf, mmmmff!” Gleaming protested. She couldn’t keep going! That last orgasm had already left her feeling exhausted. She was simply too sensitive!

“I can cum more than once, you know, just that this time it’ll both be inside your pussy, not your mouth,” Dusk offered, misunderstanding Gleaming’s protests. “Like I said, I’m going to make certain you’re pregnant, and what better way than to cum in you twice?”

Gleaming wanted to say ‘No!’, she wanted to protest. But her body refused. It was going to see this through to the end, no matter what. The very first time Gleaming would be impregnated needed to be a special one.

Instead, her cunt swallowed up Dusk’s stallionhood even more, something she wouldn’t have thought possible. Dusk seemed to be moving faster than before, with a frantic energy that belied just how much he wanted this, as much as Gleaming did herself. His cock moved back and forth, stroking her well-lubricated inner walls.

Gleaming trembled. Were it not for the ball gag, she would have been biting her hooves, as pleasure transformed into an exquisiteness so divine it even encompassed pain and nausea. It was all she could do to hang onto the cliff of consciousness, a single hoof holding onto a thin outcrop of rock.

Then Dusk came into her again, his stallionhood throbbing with heat.

Then Gleaming came, and then she blacked out.

“Are you OK, Gleamy?”

Gleaming Shield squinted. It was dark out, so she slowly managed to open her eyes, quickly adjusting for the low light.

Then she opened her eyes and realised she was in her room, though the lights had been dimmed.

“Ah, good, you’re awake. I was worried for a minute there. Did something happen?” Dusk Shine asked, waving a hoof in front of her. “How many hooves am I holding up?”

“Just one,” Gleaming said, attempting to deadpan but lacking the energy to do so. Then she blinked, and realised what had caused her to black out. “Well, you did it, Dusky. You finally made me cum so hard I blacked out.”

“Aw, shucks,” Dusk said, rubbing his head with a hoof. “That isn’t necessarily a good thing, you know. Blacking out could be associated with low blood sugar levels, or-”

Gleaming cut him off with a hoof. “None of that tonight, I don’t want to hear any of it, I just want to cuddle now, mmkay?”

“Oh. Oh, right,” Dusk said, blushing. “Um, just one more thing that I picked up today, I want you to wear it.”

Wear it? What is it? A horn ring, or or a hoof band perhaps? Gleaming thought to herself. Quickly wiggling various body parts, she found she was still wearing the collar, but the rope holding her tail in place and the spreader bar on her back legs had since been removed.

Instead of either of those options, Dusk held up a plug. “To go in your pussy,” he said. “I don’t want you leaking anything out tonight, you hear?”

Gleaming swallowed. That wasn’t quite what she had expected. But she wasn’t adverse to it either. Climbing up onto her hooves, she turned around, and lifted her legs. Cum was already beginning to leak out of her. Even in this, her brother was apparently prepared for everything.

“There, there,” Dusk said, coaxing Gleaming as the plug entered her cunt, travelling in a ways until it was finally in nice and tug, sealing off the flow of any more stallion seed from leaving. It wasn't a cock, but it was something. “Congratulations, Gleamy. You’re going to have a foal.”

“C’mere, you big lug,” Gleaming growled, grabbing Dusk Shine and pulling him down to the bed. “You fucked me so hard tonight I blacked out. You’ve bred me and yes, I’m happy. But now, I just want to cuddle with my stallion, my big brother.”

Dusk snorted, but he didn’t resist her efforts as she hugged him in close. Instead, he cast magic to turn off the lights and pull the blanket over top of the two ponies, mare and stallion, sister and brother.

Gleaming Shield went through a brief breathing exercise as she snuggled her head up against her brother’s barrel, enjoying the feeling of his fur against her head. Tomorrow would bring new things, and new paperwork, as she would be filing to leave Canterlot’s Royal Guard and join the new, minimalist troop in Ponyville for the new Prince. But right now, she had friends, family, fortune, a big brother best friend forever and a foal on the way.

What more could a mare want?

In Which the Friendship Castle Teases Gleaming Shield

“Oh wow.”

Gleaming Shield found herself amazed as she stepped hoof into the new crystal castle that had appeared on the outskirts of Ponyville.

“I’m thinking about calling it the Friendship Castle,” said Dusk Shine. “There’s even a sort-of throne room a few rooms down, with a throne for each of my friends and Spike.”

“Never mind that, where’s the washroom?” Gleaming asked.

“Again?”

“You try carrying a foal around who’s constantly pressing down on your bladder,” Gleaming retorted.

“Well, there’s one over there,” Dusk said, pointing at a random door amongst a row of identical doors.

“Good,” Gleaming said, casting a spell with her horn to leave a small bit of blue colouring on the door. Unlike her brother, she didn’t have a photographic memory capable of remembering which door led where. “Point out to me every washroom you remember, so I don’t have to go searching later.”

It was sad, losing the treehouse Gleaming and Dusk had lived in for a little while, but the Tree of Harmony appeared to have outdone itself by giving the two ponies and Spike a new place to live. With the amount of room they had, Gleaming no longer needed to fret about finding a place with more than two bedrooms once her firstborn and Spike both grew up.

To her eternal lamentation, Gleaming was in the category of mares who had begun to show very early in their pregnancy, and had suffered for it as she was teased on a daily basis about the foal she was carrying. Now that she was eight months in, the teasing had subsided, but the way others fawned over her was just as embarrassing.

“Speaking of which, how is the little one?” Dusk asked as he pressed his ear against Gleaming’s belly, determined to hear the heartbeat of the foal growing in her belly. Something like that, for example.

“I’m fine, Dusk. Really, I am,” Gleaming insisted. “Discord made certain no harm came my way, or the foal’s.”

To Discord’s credit, not a single pony had actually died in Tirek’s rampage. That he had kept the mad centaur away from hospitals had been a significant mark in his favour. Gleaming had been visiting her parents at the time, and had hidden away in the basement, no longer in peak physical condition to go fight Tirek. She didn’t care to think about what would have occurred had she tried. Likely, she would have attempted to attack Tirek, only to have her magic sucked out, basically being completely ineffective against him.

“Don’t care, I’m going to do it anyways,” Dusk said, nuzzling her stomach some more.

Gleaming reddened at the open affectation, but didn’t push him away. “At least please try not doing that when Rainbow is around,” she said.

Dusk snorted. “After all the times he bragged about bagging a mare, it’s the least I can do to show him up. Maybe he’ll work up the guts and be brave enough one day to pop the question to the twins. You might even have grandfoals by then.”

Gleaming Shield chuckled at that. Rainbow Blitz was many things. Loyal was one of them, but notably averse to settling down was certainly another.

She trudged slowly along the hallways, Dusk walking behind her every step of the way, careful to catch her if she should fall. Honestly, I’m not fragile, Gleaming thought, but she didn’t give her brother and husband any grief over it. Dusk Shine was just honestly protective of his wife and foal-to-be, and Gleaming valued that protective instinct.

“But you know, I toured this castle as soon as it appeared, and I found a few curious things,” said Dusk.

“Oh? Like what?” Gleaming asked.

“Something like this, I suppose,” Dusk said, as he opened up the first door of a new corridor.

Gleaming looked in, and her jaw dropped. Of all things, it was a maternity ward. But instead of a large ward that she had seen in the clinics in both Canterlot and Ponyville, this was large enough to serve just a single family.

And there was a milking machine right against the wall, meant for a mare to milk herself to be able to feed a foal at a later time.

“And you know, I found a hallway of bedrooms earlier,” continued Dusk. “One large master bedroom with bathroom, but with four cribs in it. Then in that same hallway, there’s a bedroom that seems perfect for Spike, but after that, there’s twelve more bedrooms.” Leaning in, he whispered huskily, “Just about enough for a dozen foals to live in as they grow up.”

Gleaming froze up. The castle seemed to have sprouted from the ground personalised for Dusk and his friends, as he had earlier mentioned about the throne room. But it seemed to go beyond that, as the castle had also built enough bedrooms for all her future to live in.

Even the castle seemed intent on getting a poke in at Gleaming Shield.

“Oh, come on!” Gleaming shouted, looking up at the castle’s roof and shaking a hoof.
