Luna must atone for her crimes as Nightmare Moon. Prince Solaris proposes an... interesting idea.

After The Nightmare has been banished from Luna following the Elements of Harmony's magic attack, Luna is brought before the Prince. Though she is his beloved sister, not even he can simply waive her punishment. As a second banishment seems unavoidable, Solaris pitches an idea to allow Luna to escape a harsh penalty. Unfortunately, she doesn't seem to be too high on the idea.

A Sweet Taboo

To her surprise, this was the first time Luna found herself bound by metal chains.

When she was younger, she could count the number of people stronger than her on her hands. When she embraced the power of the nightmare, she’d only need one. But as she shuffled through the castle she once called her home, the iron around her wrist kept her still.

Guards flanked her sides, keeping a close watch on her. They held her arms in place with firm grips, all but pulling her along. The clink of rustling chainlinks was the only sound echoing through the halls. Even if Luna was up for conversation, she doubted she’d get even a peep out of these guys. She sighed and returned her gaze to her feet.

The entourage stopped in front of a set of large doors. Ones that Luna recognized. She’d often ended up here when her parents summoned her for a scolding. This time, it'd be a little more severe than that. Her ears drooped, and she took a shaky breath. It had been so long since she’d last been in the audience of her family. To say it was nerve-wracking would be an understatement.

“You. Get the door.” The guard on Luna’s right arm barked an order at another. He rushed forward and pushed it open as he was told. The creaking of the old wood and metal hinges filled the air, along with a slight draft from within. Luna took another shaky breath as the interior came into view.

The grand hall. A wide chamber meant for court discussions and balls, occasionally. At least, that’s what Luna remembered her parents using it for. Near the far end stood two monumental thrones side by side. Only one was occupied. The guards of Luna’s escort flocked to either side of the room, standing near the pillars of its foundation. Each stood as solid as granite. With a small shove, Luna was ushered forward.

Once she reached the middle of the room, she fell to her knees. Only then was she released from their hold. With hurried steps, they retreated a few feet behind her, on guard in case she tried to escape. She looked at them for a moment before turning her attention back to the thrones. The stallion sitting on them had gotten up and began his slow descent down the stairs. As he got closer, Luna’s nerves began to climb higher.

“You sure do know how to surprise me, sister.” Luna watched him as he descended the final step. His body was lithe but well-defined. His mane flowed with magic like hers but with the warm colors of the day rather than her starry night. His dark burgundy eyes exuded an unflinching power Luna couldn’t put into words. A kingly presence. “I didn’t even have time to bring out the hors d'oeuvres.”

“We were not expecting to visit either,” Luna explained. She averted her gaze, a wave of shame overcoming her. “We… lost control and broke free of the magic binding Us.”

“Ah... I see.” Solaris looked at the guards behind Luna. “Please, leave us.”

“W-What?” The bewildered tone was shared by Luna and the guard. Though only the guard continued speaking. “B-But your highness… She's a dangerous magician! She could possibly get the better of—” A single raised hand was enough to kill the stallion’s sentence in his throat.

“I am not the same naive young stallion I once was.” He shook his head. “Should an issue arise, I will handle it myself. Besides…” He looked down at Luna, his piercing gaze softening. “I’d like to spend a little time with my sister. So, if you’d please?”

The guards were reluctant, but couldn’t disobey a direct order from their prince. One by one, they filed out of the large room until the two in the middle were the only ones left. Once Luna heard the door click shut behind her, her nervousness began to skyrocket. Alone in a room with the one person she betrayed and nearly killed a millennia ago. Solaris wasn’t one to hold grudges, but she wasn’t sure if that extended to attempts on his life. She took a deep breath and met his gaze from her knelt position.

“So? You’ve isolated Us from the rest. What now?” Luna narrowed her eyes at Solaris, who watched her with a cautious expression. “Perhaps punishments have evolved over the millennia. We wonder what could be in store for Us.”

Despite her words, Solaris kept completely quiet. There was no animosity behind his eyes, which only made Luna more worried. She swallowed and began to speak again, but his horn’s yellow glow made her catch herself. She flinched as she felt the magic wrap around her wrists, near the shackles that bound her. She winced in preparation for pain but only heard the thump of metal crashing to the floor.

“Welcome back, sister.” Solaris lowered his hand for Luna to take and put on a friendly smile. Skeptical, she took his hand and got to her feet.

“Y-Yes. We have returned…” Luna rubbed her wrists while she studied her brother’s face. He, meanwhile, covered her hands with his own. His face warped with worry.

“Do you still feel the grip of the Nightmare?” Luna felt the softness of Solaris’ palms as he brushed them over her hands. His demeanor so far had managed to surprise her.

“No, brother. Not anymore.” Solaris hummed.

“Good.” He returned to normal and offered her another friendly smile. “I’ll have to remember to offer those girls a reward.” Luna furrowed her brow. Something wasn't right.

“This reunion has been enjoyable, but… is a punishment not in order?” Luna swallowed, bringing everything back on track. If she was going to get penalized for her lack of self-control, she wanted it to start as soon as possible. Even if such a thing meant another thousand years alone...

“I guess it is.” Luna flinched. Solaris let go of his sister’s hand and turned his back to her. Following his gaze, Luna realized he was staring up at the two thrones. “But… I don’t really want to banish you again.”

“Oh?" asked Luna. Her tone made it clear that escaping banishment was ideal. She took a sigh of relief. “Then... what do you have planned for Us?” Solaris looked back and studied Luna’s gaze. His eyes narrowed and he smirked.

“You truly wish to atone for your crimes, right?” The features of Solaris’ face darkened. A shiver ran down Luna’s spine.

“Yes,” answered Luna with a voice full of determination. Her resolve strengthened. “If there is something We can do to avoid a second banishment… it will be done.” In the face of her declaration, Solaris’ expression shifted. He stepped forward as if to challenge the legitimacy of her words.

“If you’re willing to do anything... then that makes this simple.” Solaris took a step forward, closing any gap the two had between them. Startled, Luna stumbled backward, falling into her brother’s strong grip. His hand rested along the curve of her back, just above her hips. Her attention flickered from it back to his face. “Lay with me, Luna.”

“Lay with…” Luna’s sentence trailed off as she parsed his request. Solaris seemed to enjoy the look of confusion on her face, given his smirk. “You couldn’t mean…”

“Yep. It’s exactly what you’re thinking.” The hand that lay idle at his side traveled up her front and rested on her chest. She jumped as he gave her breast a squeeze through the fabric of her dress. “I want to sleep with you.”

“Have you… gone mad?” Again, Luna seemed more confused than angry. Yet, no matter how much she waited for the jest, Solaris didn’t pull back. She reached up and grabbed his forearm, taking note of its firmness. To her surprise, he relented and stopped his squeeze. “Have you grown so weary of this era’s mares that you seek the comfort of your own sister’s bosom?”

“I’ll admit, as the prince, there is no small line of mares looking to secure a spot next to me,” he said with a chuckle. The thumb on his hand laying on her breast swiped over the fabric, nicking her nipple underneath. She jumped in surprise, which seemed to be Solaris’ goal. “I suppose that aspect of society hasn’t changed in one thousand years.”

“Y-You seemed quite content bedding them if Our memory serves.” She bit her lip and looked into his eyes. “What made you turn your gaze to Us, your flesh and blood?”

“Well, I’d be lying if I said the thought of breaking a taboo didn’t turn me on.” Again, he thumbed over her breast, and again, it sent a wave through her.

“It seems that you’re the same perverted beast…” Luna squeezed his forearm and he retreated again. “Even after a millennium.”

“And it seems that you are still the same beautiful mare whose presence I was blessed to share.” Luna grumbled, clearly dissatisfied by his blatant flirting. Solaris laughed at her frowning face, then pulled away from her chest. Instead, he reached for her hand, locking their fingers together. “So? Do we have a deal?” Luna studied him, waiting one final time for him to give up his jest. Yet, by the look in his eyes, she knew that he meant every word he said. She sighed, then squeezed his hand in hers.

“Do We have your word that there will be no punishment should We go through with this… whatever this is.” Solaris smiled.

“Of course.”

“No. We require a more formal declaration.” With her other hand, she jabbed her finger into his chest. “Swear on your name and honor.” Solaris’ eyes widened, but after a few seconds, he nodded.

“I swear, as Prince Solaris, the current ruler of Equestria, that Luna will not face any punishment.” He grinned. “That is… after she sleeps with me.”

“Yes… of course.” With another sigh, Luna looked off to the side as she continued. “This is adequate. We... yield to you, brother.”

“Then there’s no time to waste.” Solaris’ horn began to glow once more. Surrounding them was the familiar clutches of a teleportation spell. With a pop of magic and a burst of heat, their surroundings changed in an instant.

Once she got her bearings she examined her new location. It was a large bedchamber adorned with sun-emblemed banners and expensive items. There was a dresser longer than she was tall to her left. To her right was a grand window overlooking the many buildings of the capital city. Straight ahead was the room’s namesake: a bed large enough to fit many at once.

“Nobody will bother us here.” Solaris put a hand on each of her shoulders, pulling her close to his chest. “Of course, that means we can be as loud as we’d like.”

“We can only assume how many mares have heard that since We have been gone.” Solaris chuckled.

“Would it surprise you to know that you’ve been the first?” His hands traveled forward, sloping off the curve of her breasts and down to her nipples. Again, as his fingers brushed past them, a shiver ran down her spine. “Other than a few servants delivering news, or the occasional cleaning, I rarely let anyone in here. Especially not for this.” Unlike before, he took a firm hold of her breasts, massaging them through the fabric. Even with a bra on, she could feel his circular rubbing, poking, and prodding. “Speaking of a long time, sister. Your speech is pretty strange for this period.”

“W-What do you expect from Us?” she asked with a deep breath. “A thousand-year-long exile didn’t do very much for Our social skills.” Solaris pinched through the fabric, ripping a loud hum out of Luna. She grumbled and turned her head. “Is this touching necessary? We would like for this to be over quickly.”

“Hmm, trust me. You’ll appreciate this soon.” He leaned down to her left ear, then further down to her neck. He rubbed his cheek against hers before planting a kiss on it. “Hey, why don’t you try speaking like me? If you’ll be spending your time in the present, you might as well get used to it, huh?”

“We have no use for your—” Luna’s body shook, and she nearly fell over. A loud, sudden yelp slipped through her tight lips. Solaris had pinched down on her nipple harder than before. A wave of heat radiated throughout her body. It felt like a great flame was building up in her core.

“I think this is a good way to teach you.” He rubbed over the nub of her nipple through the fabric again. “If you use the royal We, I’ll give you a pinch. Deal?”

“T-That is ridiculous!” breathed Luna. “We will not—” Solaris hooked her nipple between his thumb and index finger, and her body shook in anticipation. “Wait! I… I understand…”

“Good.” Solaris kissed her neck again, then moved his hands to one side of her chest. With one, he grabbed her breast tight, with the other, he began flicking her nipple like a switch. “You’ve grown into a beautiful mare. I can barely fit your boobs in my hand.”

“We do n… I don’t feel flattered by that,” huffed Luna. She grabbed hold of the bottom of her dress and let out a shaky sigh. “S-Stop this massage! This is pointless…”

“Hmm. You’re right. Let’s move on.” Solaris let her go and wrapped his arm around Luna’s shoulder. Leading the two to the bed, Solaris urged her to lie on her back. Luna obliged, allowing her brother to hover above her. She felt the heat of embarrassment on her cheeks and turned away. “But it’s not like that was all pointless. Here, let me show you.”

Before Luna’s confusion could be answered, Solaris reached for the bottom of her dress. Slowly, he pulled it up, above her stomach and chest, until it rested bundled up near her neck. The heat from Solaris’ studying gaze traveled all along her slim, lean body. He hummed as he reached for her chest, her bra the only thing protecting her from his bare touch. Even that didn’t last long. The front latch design was child’s play for his nimble fingers.

Yet, instead of going for her newly exposed breasts, his eyes wandered elsewhere. Down her stomach and past the hem of her panties. Luna swallowed hard. He reached for her stomach and laid his palm on her belly button.

“See how wet you’ve gotten from just a little bit of touching?” Luna let a small moan slip through as he traced her pussy lips through her panties. She pursed her lips to keep it from happening again. “I guess my little massage felt pretty good?”

“No. This is just… a normal reaction.” Solaris chuckled, then slipped his fingers past the hem. As one finger nicked her clit, she flinched, grunting through grit teeth.

“So you won’t mind if I continue, then?” In the same breath, Solaris slipped two fingers past her lips and inside her. No amount of willpower could keep Luna’s moan from coming out. She took a few shaky breaths, moaning as his fingers traveled deeper and deeper. He scraped at a particular wall like he was tickling her. As he expected, Luna let out another flighty moan. “Sister… you know it’s alright to feel good when I do this, right? You don’t have to hide your pleasure.”

“We… I am not pleased.” Luna groaned. “Your c-caresses mean nothing.”

“You’re moaning.” Solaris leaned down to her tits and licked her nipple with the tip of his tongue. This close, Luna was sure he could feel her twitch and sputter. Still, she ground her teeth as hard as she could.

“B-Breathing,” she huffed, her head leaning back. “We are just breath—” Luna yelped again, as Solaris took a small nibble of her nub. She shoveled air into her lungs, desperate to get back to her stoic expression.

“There’s that royal We again.” He wrapped his mouth around her nipple and began sucking on it like a lollipop. Luna’s toes curled inward to her soles, and she grabbed the sheets below her. Waves of heat pulsed from all over her body, from her heart to her fingertips.

“C-Curse you, brother!” She grumbled. Her every breath came out more like a moan than not. “Curse you straight to Tartarus!”

“Well, this cursed brother of yours is about to make you cum.” Luna’s eyes widened. His slow-pumping fingers down below began to rapidly pick up speed. A wet, squishing noise began to fill the room, along with the thick smell of sex. Luna lifted her legs into the air, her moans climbing louder and higher. She shut her eyes as hard as she could, preparing for the explosion set to go off in her pussy.

And just as she suspected, she came. Hard. She shivered like she'd gotten caught in a blizzard, but her body never felt more on fire. Her legs shot out straight and a great wet feeling dripped out from her bottoms. Slowly, she returned back to normal, shoveling air into her lungs with quick gasps. Solaris hummed and pulled his hand away, then hovered it above her body. The sticky liquid splattered all over his fingers, palm, and wrist, dripping off of him like honey. All the while, he had that same smug grin on his face from before.

“Did you like that?” He brought his hand to his face and licked the juices off. Though there was so much, he couldn’t possibly get it all.

“A-Abysmal…” Luna huffed. She put her hand over her face, trying to hide her clearly flushed expression. “I felt nothing. Nothing.”

“Not even that then, huh?” Solaris chuckled, then left the bed. Luna wondered if he was giving up and removed her hand to see. Instead, as she looked down at him, he grabbed hold of her legs, behind the knee, and folded them in on herself. He lined his face up with her dripping pussy and licked his lips. “I’ll try my best technique, then.” Luna’s heart fluttered as she realized what was next in store for her.

“F-Fool! I am already prepared! Just p-put it in and get this over with!” Despite her pleas, Solaris continued forward without pause. He inched closer until the flat of his tongue lapped at her lips like a dog. A long sigh turned into a moan while he grazed on her.

She reached down and grabbed his head. A vague attempt to stop his assault that only made him dig deeper. He pushed past her lips and squeezed through her pussy, reaching just as far in as his fingers did. The major difference was just how active his tongue could be. He could be scraping along one side before switching to quick licking on another in a heartbeat. Luna squeezed his head, hoping to dissuade him even a little bit. To her surprise, he actually did pull away.

“I won’t stop until you admit you like it.” He chuckled, then stuck a finger inside of her. “Your body is honest. Why can’t you be?”

“I… hmm… I am h-honest— haah.” Solaris returned to her pussy, licking and circling her clit like a lollipop. Her grip on his head loosened as strength left her arms. It was as if he was sucking it out of her with every drop of cum she leaked into him. The fire began to build again. She lifted off of the bed, arching her back. Again, she was powerless to stop herself from cumming.

With a grunt, Luna let the fire flow out of her once again. She shook and sputtered, leaking cum right down Solaris’ throat. He pulled away from her, letting the last of her resistance stain his expensive sheets.

“So?” he asked expectantly. “How was that?” Luna took a few deep breaths before she finally croaked out her answer.

“Adequate…” She turned on her side, looking away from Solaris and off toward the window. With a satisfied hum, he slipped behind her, wrapping his arms around her side and groping her breast. He grabbed control of her nipples again, relighting that fire in her belly. “Don’t get ahead of yourself. You’re still only adequate. Mere steps away from subpar.”

“Even though I made you cum twice?” he teased, rubbing her nipples. She let out another shaky breath, holding in her moan again. She knew that giving him that inch would cause her to lose a mile. So, she held on firm, her determination reinvigorated.

“Incorrect. I… have yet to be satisfied,” she lied. She hoped that without him looking at her face, it would be hard to call her bluff. “Let us finish this already.”

“You have a point. Let’s get on to the main course.” With his magic he pulled at the hem of her panties, pulling them down her leg with ease. They were soaked through by now anyway. She had no use for them. Behind her, she could hear the zip of pants becoming undone, as well as the shuffling of boxers being moved. She swallowed hard, waiting for the sensation to come through. “Hey, sis… want to make a little bet?”

“A bet?” she repeated. “Elaborate.” Solaris hummed in her ear.

“I bet that I can please you faster than you can do the same.” His hand slipped down the curve of her chest and over her stomach, resting under the belly button. His magic worked its way from his horn to his fingertips. Luna could feel the heat of a spell transferring to her belly. After a few seconds of silence, a mark began to appear. A heart surrounded by curving lines and patterns. Once all was said and done, it almost looked like a womb.

“What is this, brother?” He tapped the heart in the middle with his finger and it responded with a small ding.

“This is a contraceptive spell. The strongest that Equestria has ever developed. As long as this spell is in effect, it is impossible for you to become pregnant.” He chuckled as he explained. “But this is one of my own creations. A small twist on the original concept.”

“What foolishness have you done now?” asked Luna, a bit of worry creeping into her voice. Solaris hugged her close.

“That’s where the bet comes in.” He rubbed her belly gently. “This contraceptive will keep you from getting pregnant. But, that's only if you don't get too aroused.” Luna’s eyes widened. Everything became clear to her before he even said his following words. “But… after you cum, your body will begin to ovulate. Pregnancy will become unavoidable.”

“B-Brother, this is…” Luna’s sentence was cut short as he finally revealed his hand. Slipping through her thighs, slick with her own cum, was Solaris’ cock in its full glory. Just its appearance made Luna’s heart rate spike. “I-I’m… w-we can’t—”

“If you win, you can have the world at your fingertips.” He moved his hips, sliding his shaft in and out of her thighs. Luna shivered with delight, to her dismay. “Anything in my power will be yours. But if I win…” He rubbed his hand over her stomach. “You have to let me cum inside.”

“Inside…” Even just the mention of it stirred her up. There weren’t enough words in the world to could describe the fire welling up in her loins. Luna knew that her body wanted him, despite her objections. But if she admitted that…

“I’m coming, sister.” Luna’s eyes went wide as she realized his tip was knocking at her door. She was so incredibly wet that she was sure he’d slip right in. Her breaths became ragged with each slight push he did. Until finally, he broke through.

A thousand years without any stimulation left Luna tighter than a vice grip. Solaris moaned and held her close as he slipped each inch inside. Luna was lucky she could even keep herself sane. A long, guttural moan was all Luna could manage once his tip finally smooched her womb. She quivered as she realized just how deep Solaris reached.

“Ooh… God yes,” Solaris moaned again. “Luna… this is by far the best pussy I’ve ever been in. Hmm… You’re a goddess.” Luna couldn’t respond, saliva dripped out of her mouth agape. The beginning of tears from the pressure welled up in her eyes and slid down her cheeks. Just the presence of a thick, twitching rod inside of her was enough to put her close to the edge. And thanks to the spell on her stomach, Solaris knew it. “Sister… the spell was already nearly broken. Am I really that—”

"Be silent!” begged Luna. She grasped at the sheet and caught her breath. “Do not speak. Do not gloat. Just… t-take me.” Solaris hummed in surprise, and Luna realized her words. Immediately, her cheeks flushed red. “T-To get it over with quicker! Do not dilly dally!”

“Alright.” Solaris pulled back a bit, then pushed in again, ripping out the same flighty moan from before. He chuckled, then kissed Luna on the neck. “Anything for my dear sister.”

The retreat was just as slow and intense as his approach. Gliding through her soft, velvety folds, he exposed half of his shaft before barging in once again. Unlike the sharp thrusts she’d expected from a horny beast, he was much more elegant with his sex. His hands traveled from her belly to her breasts. Once again, he found enjoyment in kneading them. His touch was softer than the silk sheets they were making love on.

“Do you like this?” There it was again. That question Luna couldn’t answer. A few deep breaths, and a small moan later, she found her answer.

“I am fine,” she answered simply. “At the very least, it doesn’t hurt.”

“That’s good.” He nuzzled into her neck, pecking her with incessant soft kisses, like a kitten. Worse, Luna was beginning to feel their impact. They rippled through her body like small heat waves. Her heart fluttered with joy. “Tell me if it starts to. I don’t want to harm you.”

“I-I know, brother.” His slow pace was starting to drive Luna crazy. Like filling up a glass of water, one drop at a time. Each thrust dripped a bit of arousal into her cup like a leaky faucet.

“Was it lonely on the moon?” Luna’s eyes widened. A question like that now? Before she could think of what to tell him, he pressed his tip against her g-spot, melting her on the spot. The words came out through a hummed moan.

“Lonely doesn’t even begin to describe it,” she huffed. “It felt as if I had nothing. No friends or family. Surrounded only by the voices of my enemy. For a thousand years… it’s a miracle I even stayed sane.” Solaris pulled her closer. His embrace felt warmer than usual.

“Not a moment went by when I didn’t think of you.” His words struck Luna straight in her chest. Her heart beat with more zeal than before. “Had I been stronger, you may not have had to leave me.” He kissed her again, and Luna squealed in surprise. “I promise that you’ll never be lonely again.”

Luna closed her eyes tight. Long ago, her body had already succumbed to Solaris’ advances, but her heart stayed firm. But, if he really meant was he said... it threatened to break it wide open. The heat from her belly spread out across her body until it felt like she could burst into flames at any moment. When she opened her mouth, it came out as a croak.

“I-I understand already!” she yelped. Tears began to flow down her face. An overwhelming sense of joy flooded her mind. She reached for his thigh behind her and gave it a tight squeeze. “So please... for the love of everything under the moon’s glow… faster…” Solaris chuckled behind her.

“Of course, sister.”

In one smooth movement, he reached under her body and lifted her up. His dick slipped out, but it seemed like he had other plans. Sitting in his lap, Solaris lifted Luna’s legs upward until her entire body was laid bare. His hands snaked up and grabbed her breasts, keeping her locked in the revealing position. His cock twitched in front of her, eager to get back to his duties.

Then, without warning, Solaris poked through and slammed into Luna’s pussy. A jet of clear cum forced its way out, shooting at the floor and splattering against it. Luna wailed as the sudden force shook through her body.

And Solaris kept that energy going. The slow pumps were gone, replaced with battering thrusts that shook Luna to her core. His speed and precision were impeccable. Every heartbeat, his tip squished hard against the back of her pussy.

Finally, Luna let herself go. Her stubbornness melted with her loud whines and groans. This was the animalistic lust she’d expected. Only now did she realize it was also what she wanted. Even while he barged forward like a beast, Solaris was calculated. He brought his hands up to her nipples and rubbed them gently. The mix of gentle coddling and roughhousing sent her mind through a blender.

The mark on her stomach began to blink as if it were warning them of the consequences. The heart pattern had grown full, set to burst at any moment. Luna didn’t need such an indicator, though. She could feel the fire in her belly building again. And this time, she had no shame in letting it flow out.

With a sharp crackling sound, the spell broke. Following a loud cry, thick jets of liquid shot out of Luna with fervor. Solaris slammed in with a final strike, letting it trickle out of her nice and slow. Her body shook with vigor, chilling her down to the bone. Once her high came to an end, Solaris ripped his cock from her leaking pussy, letting another wave of her cum slip out. She took long, deep breaths, relishing in the intensity of her greatest orgasm yet.

“Luna, that was… amazing.” Even Solaris was out of breath. He released her from her position and let her lay on her back against the bed. Even now, she could still feel the mark he left inside of her. The mark on her stomach began to pulse with light. She could feel her body changing. “But… we’re not quite finished yet.”

“W-What do you…” Luna’s eyes widened. In the throes of her pleasure, she hadn’t realized that there was something missing. She looked over at her brother, realizing his dick was still at full mast. Just the sight of it was enough to make her tingle. He climbed on top of her like before, folding her legs inward like he did before. “O-Oh…”

“Want to know a small quirk of the contraceptive spell? Another one of my tweaks.” He pressed his hand to her stomach again, and the magic began shifting. The firmness of his palm pressing down on her sent a shiver down her spine. “This is not a one-use spell. With just a little bit of maneuvering…” He pulled his hand back. Just like that, the spell returned. “Hey sister… how do you feel about twins?” Luna looked away in embarrassment. She covered her face with her hand. A useless attempt to hide her excitement.

“You’ve already defeated me,” he murmured. The feeling behind her eyes had changed. She no longer looked at him as a beast but as a man. Quite a desirable one, at that. “Do as you wish.”

“That’s a dangerous thing to tell me.” He lined up his cock with Luna’s defenseless pussy. Maybe it was because she saw it in a new light, but it seemed much bigger, much sturdier than before. It twitched violently just as it pressed into her. “I might go wild.”

“If your actions from before are any sign… wild is an understatement.” Luna pursed her lips, looking up at Solaris with a shy peek. His smug grin was annoying, but Luna had since learned that trying to deny her body its pleasures wouldn’t work. Even if that pleasure happened to be her brother’s cock. She grumbled, then shook her head. “Just do it.”

At her request, Solaris poked past her lips and slipped inside her once again. She had loosened up a bit, but she was still tight enough to give Solaris pause. Luna enveloped his shaft, welcoming him with open arms to visit her deepest places once again. Luna let out a sigh of relief once he reached the back, but grumbled once she realized it came out as a moan.

“You make the cutest sounds,” said Solaris, only stoking the flames. He took her hands in his own, locking their fingers and pinning her to the bed. He smirked in the face of her embarrassment. “But, I think this would make you even cuter.”

His horn glowed yellow once again. Luna braced for some sort of enhancing magic but instead found herself in a warm embrace. Around her body, clothing began to appear, strapping itself to her. A pair of white garters wrapped around her legs and waist, and a white corset enveloped her stomach. Her hands were covered with white lace gloves, and a flower garment appeared on her head.

“This is…” Against her dark skin, the white stood out. Only one occasion could ever match this type of attire. “Do you intend to take me as your bride?”

“Of course.” The smugness behind his expression faded and her heart danced, despite her reluctance. “I told you before. I won’t leave you again.”

Solaris started to move before Luna could get her bearings. She let out a moan, squeezing his fingers tight. He lifted his hips and slammed down into Luna’s ass with a thwack. Wet, sloppy sounds of sex filled the room along with the heavy breathing from the two. Luna looked Solaris in his eyes as he pounded her, watching him like he might disappear if she didn’t. Passion lay deep behind those eyes. He looked at her not as a mare to bed, but as a lover. Though his words and actions had made that clear, Luna couldn’t quite believe it until now.

“Falling in love?” he asked with another smug grin. Luna narrowed her eyes.

“So?” she asked in a low voice. “What if I am?” A pleasant surprise flashed across Solaris’ face. He smiled, then leaned down.

Without a word, he pressed his lips into hers. They were soft enough for Luna to melt into. She pushed back against him, indulging in their taste. Once his tongue poked through, she let him in. He traced her mouth carefully and licked her tongue up and down. She tightened up below, and Solaris picked up the pace again. The bed began to creak under the weight of his thrusts. He pulled away, letting Luna moan out with pleasure.

“Sol…” Luna whined. By the way, he was twitching, he couldn’t hold it back for much longer. Luna grabbed his shoulders, pulling him down into her. “Make me a mother…!”

With a grunt and a clench of his balls, Solaris exploded inside of her. It was nothing like her own orgasms. His cum was hot and thick like lava, shooting through her with the speed of a bullet. The mark on her stomach went haywire, glowing with the power of the sun. Shot after shot seeped deeper into her pussy, eventually pooling inside of her. Solaris took deep breaths, making sure not a single drop spilled on the sheets before Luna was nice and pregnant.

And it kept coming. He didn’t slow down even for a moment. The cum he’d saved for her for over a thousand years swamped her, leaving her belly full. Soon, she could feel it slipping down the curve of her ass and onto the bed. Only then, with a final grunt, did Solaris pull out, leaving white spunk bubbling out of her pussy.

The mark on her stomach began pulsing like before. Only this time, Luna felt much… different. The feeling of being swarmed rumbled in her stomach. The tattoo shook and vibrated with the energy of the sperm. Under intense pressure, defending from millions, her little eggs couldn't handle the pressure. She let out a moan as two were split open at the same time. They solidified and became two separate entities inside her.

“Luna?” Solaris’ call brought her back to reality. She looked down at the absolute mess he’d left behind. She clenched up, letting another big bubble of cum drip out of her.

“Was this much necessary?” she asked with a frown. “I would have become pregnant with much less…”

“Sorry. I did get a little carried away.” He slipped to her side and wrapped his arms around her again. She’d gotten used to the comforting feeling that being in her brother’s arms gave her. She leaned into him, pressing her head to his chest.

“What would mother and father think?” she asked with a hum. “Bedding your own sister, and conceiving children. Maybe you were the one to lose their sanity?” He chuckled.

“I’d tell them that I found the most beautiful mare to make my princess.” Luna turned to him, pulling him in for a kiss. Solaris reacted in kind, pulling her close and indulging in her lips. After a few seconds, she pulled away and frowned.

“Quiet,” she ordered. “Your flattery will gain you no favor with me.”

“Are you sure?” His hand snaked down her back, grabbing a palmful of her ass. She huffed, then looked up at him.

“Your flattery will gain… little favor with me.” Solaris laughed, then squeezed her again.

“You know… the spell is still in effect.” He narrowed his eyes. “They say all good things come in threes.” Luna rolled her eyes, then hummed. Her lower body still buzzed with the energy of the pounding he gave her. She sighed, then pressed her hand to her stomach. The mark responded with a quiet hum and a pulse of light.

“I suppose the castle will be welcoming more than a few new members soon.”

A little epilogue chapter to extend the story a bit. If you're wondering, the reference for the dress is here (2873054). I'm not sure if I got the explanation of the dress across well, but here we are. Enjoy!

3 Years Later...

“You look cheery.”

Luna hadn’t heard Solaris’ approach until he stood at the side of the bed. The sun had begun its descent through the afternoon sky. She thought he would have been busy wrapping up his daily duties, yet here he was. His affectionate smile warmed her chest whenever she saw it. Still, she rolled her eyes and looked away.

“I was. Then a certain annoying brother of mine showed up and ruined it.” Solaris tittered, then leaned down to her side, seeking to plant a kiss on his wife’s cheek. Luna leaned into it, despite her previous objections. His soft lips against her face were another thing that warmed her heart.

“How are they?” asked Solaris. Luna looked into her lap again, where three young foals were resting quietly.

“Until an hour ago, rowdy and rambunctious,” she sighed. “Artemis and Apollo were playing poltergeist. Eos was the object.” She looked at each one as she spoke about them. Despite her harsh words, she looked at each one with a soft glance. Her fingers ran through their manes one by one. One as bright as the sun, another as dark as the night sky. Eos was the exception, with a white mane like the clouds above.

“Sounds like you could use a break,” said Solaris. Luna considered his words but returned with a sigh.

“Neither motherhood nor country leadership seems like the type to allow breaks, Sol.” He sat down next to her and looked down at his children. As energetic as he seemed, the faint circles around his eyes gave away his fatigue. With a hum, Solaris began musing on the issue.

“How about just one night, then?” asked Solaris. “We’ve both been so busy, you’d almost forget that it’s been nearly three years since you came back.”

“Time flies for immortals.” Luna furrowed her brow. “What exactly did you have in mind?” He looked up at Luna with a reassuring smile.

“I’ll be departing to Yakyakistan next week for a relations summit. My advisors have suggested I take it easy until then so I can be well-rested for the trip.” Luna didn’t even attempt to hide the worry on her face. Her brother was surely the most powerful stallion alive, yet she couldn’t help herself. She blamed it on her relatively new motherly instinct.

“How long will you be gone?”

“Two weeks,” he answered. “Which will probably feel like four without you by my side,” Luna grumbled. The flattery was nice, but the news was still unfortunate. She lifted her hand and placed it over his. “Which is why now is the best time to cut loose and relax. How does a fancy Prench restaurant sound?

“Admittedly, it sounds lovely,” she hummed. Her eyes returned to the foals peacefully resting in her lap. “But I doubt I could enjoy myself while looking over the young ones.”

“The castle has the best nannies one can hire. I guarantee it.” Solaris took her hand in his and gave it a small squeeze. “Won’t you come with me, Lulu?”

Luna pursed her lips. He knew how to make a case. She loved her children, but spending every waking moment with them had worn her down in a big way. Even still, she’d been cautious about handing over three alicorns to mere servants of the castle. Yet, since Solaris had made the suggestion, she felt a little more confident making the choice. Also, he’d called her by their childhood nickname. That had proven to sway her decisions endless times in the past. She sighed, then gave his hand a little squeeze.

“Alright…” Solaris’ eyes lit up like fireworks. His smile was contagious, as even Luna found herself smirking a bit. “I’ll leave the preparations to you, Sol.”

“You won’t regret it!” Solaris hopped to his feet and his horn began to glow. Luna watched cautiously until the spell was revealed. In front of him, he conjured a small white box. He laid the box at her feet. “We’ll leave on Friday evening. Make sure you wear that!” Before Luna could ask for any clarification, he slipped away in a flash of magic.

“As spontaneous as ever,” murmured Luna shaking her head. She checked on the foals, making sure none were roused by the sound of his teleportation spell. After seeing their resting faces, Luna turned to the box Solaris had conjured and left behind.

Unable to reach it with her hands, she grasped it with her magic. The top came off easily and she grabbed some sort of red cloth folded neatly inside. As she lifted it, it unraveled and its form became clear. Just like the fabric, her face began to beam a deep crimson and her mouth fell agape.

“He… Sol, you cannot be serious…”

The days went by slowly that week. Meetings dragged on for hours longer than they actually lasted. The three alicorns were much more unmanageable than usual, leaving Luna to rethink the trip altogether. But, as the day finally came, everything seemed to fall into place. The foals were good and went to bed early. Luna made sure that they were subdued herself before getting prepared.

She returned to her chambers, which were much quieter than she was used to. Items flew through the air as she pulled them closer with magic. Soaps, shampoos, and conditioners of all different types circled her as she approached her room's private showers. Luna had never been picky with this sort of thing, but tonight she felt it necessary.

Once she was under the hot water, she let her endless deliberation rest. She picked her soap of choice and began to lather her skin in its delightful scent. She traveled her body, leaving behind soapy white bubbles and cleansing her skin of any impurities. Though, as she did so, she wore a frown and grumbled under her breath.

“I should consider patronage at a gym…” As she spoke, she rubbed her hands over her belly. Where she used to be quite thin and lithe, she’d gotten large. She remembered how surprised she was to see her large rounded belly when she was still pregnant. It seemed as if this was a side effect of those times.

Her hand traveled a bit further down, brushing over a nostalgic mark just above her marehood. Her brother’s powerful energy still resonated there, even after all those years. Once the foals were born, they hadn’t had nearly enough time to stay intimate. Though Solaris kept her at bay with regular kisses and cuddles, Luna would be lying if she said her body was the only thing yearning for him.

She shook her head and let the water roll down her face. Tonight would be one of the rare times she would get to relax. Worrying about such things could wait until later.

After stepping out of the shower, she was faced with a thick cloud of steam. It soothed her body with its heat as she wiped herself down. In her magic, she took a comb to her flowing mane, working through the overflowing magic power with ease. Once it was as she wanted it, she finished drying herself off and stepped into her room again.

“Hmm…” Luna’s gaze was caught by the white box at the foot of her bed. She’d retrieved it for the occasion, but it still hadn’t quite clicked with her. Again, she lifted the box and removed the item inside: a revealing red dress. It was clearly made with exquisite materials, but its design left very… very little to the imagination. The one time she put it on, she felt more clothed while naked. Still, it was a request from Solaris. He was probably looking forward to it.

She narrowed her eyes. This night was probably just as important to him as it was to her. She took a deep breath, then started putting on the dress.

The outfit seemed more like an apron than proper attire. Two thin straps draped over her shoulders and met a wide strip of fabric at her back. Though they widened out near the bottom, they were still barely enough to keep her nipples from showing. The dark edges of her areola could still be seen with careful observation.

The middle of the dress was barren. That is to say, there was nothing there. Her stomach was bare, making it seem like she was wearing a bra instead of a full dress. Finally, as it bottomed out, the fabric returned to the front and properly covered her legs. The only issue was the steep cut on her left side. It was so high, her entire leg was exposed. Any passerby would get a full view of her crotch if she decided to take this out. She pursed her lips and shut her eyes in embarrassment.

“Perhaps I should wear something else after all.”

“No, no, I think it suits you well!” Luna spun on her heel quicker than a tornado, meeting the smug gaze of her brother. He was standing at her door and leaning against the frame, watching her with amusement. “Wow, it’s even better from the front.”

“H-How long have you been standing there!?” yelled Luna. She instinctively covered her breasts and crotch with her arms and flushed red in an instant. Sol chuckled, then stepped inside, closing the door behind him.

“Since you were struggling with the straps,” he answered. “Didn’t want to disturb you while you were getting dolled up.”

“You fiend…” she murmured. In her magic, she levitated her bath towel over her body to protect it from his predatory gazes. “Do you truly intend for me to go out like this?”

“What’s wrong with it?” Luna nearly cursed at him before she looked into his eyes. She could tell that he really didn’t see anything wrong with the dress. He approached her, reaching for the arms covering her delicates. With a small tug, he convinced her to reveal her figure to him. “You look beautiful.”

“I look like a fool.” She yanked her hands away from him and covered her stomach. “Pregnancy has not been kind to me. This dress would be better suited for someone with a slimmer figure.” Luna bit her lip and looked away in shame. But, to her surprise, Solaris simply laughed.

“Mares and stallions both worry about how they look here. But in my opinion…” Solaris quickly repositioned behind Luna, wrapping her in his big arms. He weaved underneath her arms and rubbed her belly. The hum of the old spell laying dormant within her made Luna hum in surprised delight. “...This is the best part. So soft and comfortable. You should take pride in it.”

“A-An odd opinion to hold, surely.” Luna squeezed his hands and turned to meet his eyes. “I’m certain that others will not agree.”

“This isn’t for others.” Solaris leaned down and took her lips by surprise. She gasped but had little time to adjust. He started massaging her belly, getting his fill of its soft plumpness. Up above, he satisfied her with peppery kisses with a few tongue battles as well. Just this tiny bit of interaction was enough to make her lower body ache. Her cravings wouldn’t be held back for much longer. After he pulled away, he eyed her body down with the thirst of a beast. His erection was felt through his pants, hard on Luna’s back.

“Should we be doing this?” asked Luna. Though her heart was beating with untamed ferocity, she calmed herself down enough to speak. “The dinner… we might miss it.”

“The dinner was only a means to an end, sister. The end goal was to spend time with my beautiful wife.” His hands moved up her stomach and underneath the curve of her breasts. Just as the rest of her body grew, so did her chest. Even her butt had gotten a bit larger since their last encounter. Solaris scanned her body, finding all new ways to please her. “Will you let me take you to bed?” Luna’s lust had reached a boiling point. Her eyes sparkled with hidden glee.

“Take me, Sol…” He hummed with delight as his horn began to glow its signature gold. The two disappeared in an instant, returning to a familiar scene from the past. Luna shivered as her eyes landed on the spot she’d been bred three years ago. Her body remembered it well.

She approached the bed first and climbed aboard the sheets. She glanced behind her, then wiggled her hips in front of him. Her attire did her no favors here. Her pussy was completely exposed in all its moist glory. Solaris approached her gingerly, his large hands grabbing handfuls of her ass and squeezing.

“I know you’ve been working hard, sister.” Luna heard him discard his pants, and her heart rate spiked. As she expected, his hard cock slapped down right between her asscheeks with a dull thud. She let out a purr of satisfaction. “Let me reward you.”

“Ooh…” Luna hummed as he slid his shaft along her butt. It had been a long time since she’d felt it, but… she almost felt as if it had gotten bigger. The prospect made her quiver. “Stop stalling, Sol. Take me…!”

“Lulu…” he leaned down until his chest pressed against her back. He spoke in her ear, sending shivers up her spine. “Do you remember the spell from before?”

“Y-Yes,” Luna buzzed. “Why…?” He slipped his hand underneath her stomach, his fingers gliding over the old mark. His fingers whirred with the power she felt before. Her eyes widened. “S-Solaris, you don’t mean to…” He laughed as the magic began to flow.

“I do.” The mark, which had kept to a low hum for all this time sprang back to life. It burst with a power that almost made Luna cum on the spot. She let out a long sigh once Solaris pulled away. “What can I say? The thought of putting a baby in you just sets something off in me.”

“Just… Just how many children do you intend for me to bear, brother?” As she spoke he stroked his tip against her eagerly waiting pussy. She whined with lust, her desires taking over her common sense at an alarming rate.

“How many can you hold?” Without waiting for an answer, he stabbed through her lips and split her folds for the first time in years. Luna couldn’t help the guttural cry from escaping her mouth once he got going. Her sexual inactivity had made her stiff. Solaris’ cock seemed like the perfect tool to fix that. “Hmm… Lulu. I’ll never get tired of that.”

“B-Brother! Hmm~” Luna made no attempt to keep her voice down now either. With each inch he slipped in, she felt her body shake with excitement. Once he finally pressed everything inside, they both let loose huge sighs of relief. “That’s the spot…” Solaris grabbed hold of her hips before pulling back. With a strong slam forward, Luna’s ass rippled under the pressure. She gripped the sheets and curled forward.

“S-Sorry sis,” huffed Solaris. It seemed like Luna had the same influence on him that he had on her. He pumped into her a few more times before pausing to catch himself. Luna, however, was constantly teetering on the edge of pleasure. “It’s been so long that I got a little excited.” Luna huffed a few times, letting moans slide out with her breath.

He continued with his stuttering thrusts until he stabilized and found his rhythm. The ferocity behind his thrusts sent waves of pressure through Luna’s body, shaking her down to her core. Still, Luna never felt more loved. She slipped down onto her stomach, and Solaris followed her down. Once again, he hovered over her, inches away from her face.

Without a word, he slipped his hands underneath Luna’s body. She shuffled to give him room, believing he would travel further up to reach her breasts. To her surprise, he began fondling her belly again, rubbing the mark with his magic. A buzz grew violent inside of her, like a vibrator strapped right to her womb.

“N-No! Not there… you…!” Luna's complaints slid through grit teeth. Her hand squeezed his wrist as he played with her belly. “S-Stop this!”

“Relax, Lulu,” hummed Solaris. Traveling up to her chest was his other hand, grabbing her supple tits with a squeeze. He swarmed her nipple with his fingers, flicking and pinching it as he went on. “Every part of you is beautiful. I love it all.” Luna shut her eyes and pursed her lips. A comforting warmth spread from her chest to her fingertips. She knew about his honeyed words but never ceased to enjoy them. “Besides... You’re close, aren’t you? You can just let loose.”

As he spoke, he quickened his pace down below. His pounding was making the entire bed creak and shake under his forceful attack. Luna’s pussy was near the brim of what it could take. A slight push over the edge was all she’d need to gush like a fountain.

“Luna…” Solaris’ voice began to shake. From the way he was twitching inside of her and how erratic his thrusts had gotten, he was close. She opened her eyes and turned to him as far as she could. He took her lips with a quick kiss. “I love you, sister.” Luna’s eyes widened and her chest tightened.

“Don’t t-tell me that now…” she murmured. With a final huff, she pressed her forehead against the sheets. Her body wouldn’t take this any longer.

Once again, Luna had been surprised by the warmth of Solaris’ cum as it flooded into her. A thick, soupy glob of molten hot spunk dug deep inside of her, shooting from his cock with bold ferocity. Luna gripped the sheets as she was filled up, the mark humming with a heat of its own as it accepted his offering to it. Once again, in her brother’s arms, she was bred.

He pulled out from her in a slow, agonizing fashion. Slipping out with a wet schlick, his seed dripped out onto the sheets, leaving Luna drooling underneath him. He rolled over and laid on his back, catching his breath.

“Amazing… I’d forgotten how good you feel.” Solaris turned to Luna with a smug smirk. “How was it for you?” Luna glanced at him with a blank expression.

“Do you fully understand what you’ve just done?” Solaris’s smugness waned, replaced by a nervous smile. “Four new heirs was unheard of even in our parent’s days.”

“Records are meant to be broken, right?” he asked. Luna’s glare made it apparent that she wasn’t as amused as he was. Still, she got up and observed the damage. As she suspected, his sticky white mess was still leaking out of her. She sighed, then turned to him.

Without a word, she mounted his body like a horse, Looking down, she could see him start to rouse at her erotic body hovering just above him. His predatory gaze returned, and Luna felt it in her loins.

But, instead of getting right back to the act, her horn began to glow. The magic dwelling in her core began to shift in her favor. The spell her womb had been bound by for years was being remade anew. Soon, she was done with her own design. A type of lock secured firmly over the heart.

“Oh? So you learned the spell!” exclaimed Solaris. Luna narrowed her eyes.

“The night is still young. And you look like you’re full of energy.” She glanced down at his rapidly hardening dick sprouting between her legs. “But I don’t want any more surprises. Am I understood?” Her look was ferocious enough to even catch Solaris off guard. He chuckled nervously, then rubbed his hands on her thighs.

“Yep, I get it,” he answered. Luna smiled, then leaned down and planted a kiss on her brother’s forehead. As she said, they still had plenty of time. And if they were going to be having another child… she’d need to savor what little free time she had left.

“Good,” she hummed. “Now… give me everything you’ve got.”
