Fireworks *

The last few days of Sunset Shimmer’s heat season were the worst.

Not because of any difficulty in dealing with it. She had, after all, gone the last few years without a single lay and had to endure the entire two weeks give-or-take of her loins feeling aflame and her mind unable to think about much other than some stallion rutting her into the ground. She was able to cover up her own smell just fine, there were plenty of salves and ointments for that, but that never did anything to quell her libido.

Her problem this time, however, was that it had come back stronger than before. An annoying thing about a mare’s body going into heat this long is that, if a mare doesn’t get pregnant, it comes back worse. She had Shining on hoof to deal with it last time she had sensed it was coming back, so her heat was sated before it became a problem.

But that was before Cadance had shown up on the scene.

Sunset didn’t have any enmity with the alicorn, and Cadance didn’t appear to be holding a grudge about the fact that she was with Shining now, but the knowledge that his ex was back and that things were going to be super-awkward for the next couple of weeks kept Shining’s libido down, in spite of his flirting the afternoon Cadance had come back.

True to their mutual promise, they had talked at length about their relationship that night. They had talked about what they were, what they wanted to be, and now with her running around, what kind of an effect Cadance was going to have. So now, Sunset had a coltfriend, was committed to seeing how far this new relationship was going,

Sunset was rather grateful for her own private chat with Princess Celestia the next morning.

“You would do well to keep an eye on Shining Armor,” the Princess had cautioned. “Because of the way his and Cadance’s relationship ended, abruptly for her yesterday and without closure for him, I do not think their feelings for each other are anywhere close to gone. Certainly not hers, but there is a good possibility his are still there as well.”

“So what am I to do about that?” she had asked.

“Be understanding,” was the Princess’ answer. “Be there for him to confess to. I do not believe his loyalty and commitment will be a problem, but if you are not there for him, and she is, you will find him drifting back toward her.”

Thus far, it had seemed that this wouldn’t be a problem. Shining was spending pretty much all of his free time with her, and Cadance seemed to be respectfully keeping her distance from them as well. She was staying in a different part of the residential wing than her normal quarters, which were just down the hall from Sunset’s own, and the few times she and Shining had come across Cadance, Cadance had given them a cordial smile and found a way to excuse herself.

“Ugh,” she thought, her thighs twitching as a sudden flash of need swept over her, almost causing her to drop the book she was trying to prise out of the shelves of the Royal Library from her hooves.

Stupid heat, she thought as she managed to catch it in her magic before it could tumble down. If only I could use my magic…

Heat was always an annoying time for unicorns. Nothing was really stopping her from using magic, as she just demonstrated, but the constant distractions it provided could cause problems if she were doing more than simple telekinesis. And due to the unusual circumstances, Sunset had been warned to keep off magic entirely when her heats were at their peak except in reflex.

Before she could lose it due to another heat distraction, she took the book in her front hooves and climbed down the rather tall shelf ladder she was currently standing on. Books were a good distraction, but it seemed like the best ones were always put on the highest shelves and were the hardest to pry loose with hooves alone.

The library was almost completely devoid of ponies today. Obviously she was there, as was the librarian, but there also appeared to be a young lilac unicorn filly browsing the non-fiction section that Sunset had seen around before, but had never spoken to.

There were usually more ponies in here, but for whatever reason, they were the only three in here today. Such a shame. The library really was a beautiful place. Tall windows with rounded tops, massive shelves stuffed full of books, murals of different moments in Equestrian history, crystalline chandeliers lighting the room and glimmering with the lighting enchantments, and several paintings that were hung in here to display rather than the foyer.

And outside of one of the windows was the training ground, where unfortunately, Sunset wasn’t able to watch Shining train today. And unfortunately, that left her with nothing else to do but read in an attempt to distract herself from her heat, at least until Shining got off.

Then he’d be getting her off.

NO! Bad thoughts! she chastised herself. The last thing she needed to do was leave a mess for the poor librarian to clean up.

To the book! The book would keep her mind off. A Clash of Queens, by George R. R. Maretin. Apparently the show had gotten really popular lately or something. Whatever the case, she was down to read it.

“E-excuse me?”

She turned to where the voice had come from. The lilac filly was standing beside her, looking about as nervous as Shining Armor had when he had first shown up in her room those two weeks ago.

She couldn’t have been more than a couple of years younger than her, with rather gangly legs, a navy-blue mane and tail highlighted with a purple and a magenta streak, and the purplest eyes she had ever seen.

But her mane and tail were in disarray, her coat looked a mess, she was blushing furiously while she constantly shifted her back legs, and she smelled.

Sunset knew the smell of heat, and this filly reeked of it.

“S-sorry,” the filly recoiled as she saw Sunset wrinkle her nose. “I know I’m a m-mess right now.”

“Can I help you?” Sunset asked not unkindly, leading the filly over to the table she was going to read at and setting her book down.

“I, uhh…” the filly looked away awkwardly, “I n-need your help.”

“Oh? What kind of help?”

“M-my heat,” she admitted, her already-red face going even darker. “P-princess Celestia said I could f-find you here.”

“Princess Celestia sent you to me?” Sunset tilted her head. “What’s your name?”

“I’m Twilight Sparkle,” the filly answered. Finally, a reply without a stammer. “I’m another one of her s-students.”

That’s why she had seen this filly around! Sunset knew she wasn’t Princess Celestia’s only personal student, but she hadn’t gotten to work with any of her fellow proteges. And that would also explain why Princess Celestia sent Twilight to her, considering she was the most senior of the four apprentices, even though the other two of them were currently off in Mareis, Prance for something.

“I’m Sunset Shimmer,” she smiled at her younger counterpart. “Is this your first heat?”

“N-no, but it’s… why is it lasting s-so long?” Twilight whined, before she suddenly shuddered. “M-my heat season wasn’t supposed to las-st more than a f-few days.”

“Oh,” understanding flooded through Sunset. Right. She remembered her first “Celestine Heat,” as one of the older apprentices had called it. It had been a nightmare that first time, when she had no idea when it would end, and now here was Twilight Sparkle suffering through it as well. “Right. It’s good you came to me. I know why it’s lasted this long.”

“You d-do?” Twilight asked. She looked just pitiful. Her eyes were almost pleading on their own for her help.

“Yeah,” Sunset nodded, before swiping up the book and heading over to the check-out desk. “First thing’s first, let’s go get you cleaned up. You’re a mess.”

“I kn-know,” Twilight sighed. “I’ve spent the last two w-weeks cooped up in my tower.”

Eesh, it probably smells even worse in there! she realized. If it was anything like how the Dusk Quarter had smelled after her first Celestine Heat…

“Come on, Twilight,” she said as she stamped out her book at the desk and then slipped it into her saddlebag, which she promptly settled on her back. “We’ll go get you cleaned up, and I’ll get your tower smelling back to normal. then we’ll talk, alright?”

“A-alright,” Twilight nodded.

Twilight led Sunset to her tower, where Sunset drew up a warm bath in her bathroom, but took time to mix up a Soothing Salve from ingredients Twilight kept in a locked cupboard and then add it into the tub. Potions had always been her strong suit, and this was no exception. Once the bath had turned a pleasant shade of lilac, not too far off of Twilight’s own coat, she ushered Twilight in, told her to soak for several minutes, and get washed up. It wouldn’t do too much to actually quell the heat, but it would certainly leave her feeling a lot more at ease when she got out, and it would dampen her quaking.

Cleaning out the tower, which had to have at least half as many books as the entire library did, was a bit more difficult, but not too bad. Mostly it involved throwing open the windows, getting some air circulation going, and using a magic spell to force-cleanse the carpeted sections of the floor. At most, it took fifteen minutes. She did, after all, have a bit of experience when she’d had to do it to her room.

By the time she finished, Twilight was clambering out of her bathtub and wrapping herself up in a towel. Not only did she smell loads better, she seemed to be carrying herself with renewed confidence and she looked lighter. There was no slumping like she had been when she was embarrassed, and that alone did wonders.

“Thank-you,” she sighed as she wrapped a towel around her mane. “For all of this, I mean.”

“Hey, it’s no problem,” Sunset smiled cheerfully. “We apprentices look out for each other. Just bear in mind, this isn’t a permanent solution to your heat, though. It’ll come back. I just bought you a few hours so you can go find your coltfriend and get it taken care of.”

At the mention of a coltfriend, Twilight blushed again. “I… don’t have a coltfriend.”

“You don’t?” She was rather surprised. Twilight did look rather cute. Perhaps she swung the other way? “What about a marefriend?”

“N-no,” she shook her head. “Just me.”

“Oh.” Well, that wouldn’t be good. She’d have to endure another few nights before it went away. One of the few nice things about having to go through these Celestine Heats was that they were predictable, both in onset and length. Sunset guessed that’s what happened when one’s biological clock was attuned to a reigning sun avatar.

Wait a minute, a sudden thought had occurred to her. Maybe she doesn’t have to wait it out. I did promise Shining something special.

“Is there any way at all to get rid of it completely?” Twilight asked, drying herself off. “N-not permanently,” she quickly added, going a bit pink, “if that’s even possible, but… for the rest of this season?”

“Sadly, only one way,” Sunset answered, hashing out the plan in her head. “Only happens if a stallion… ah, cums inside.”

“O-oh,” her face went red again.

“I mean, sort of,” Sunset shrugged as she clarified. “Since most mares don’t have to worry about two-plus week long heats, it’s usually one and done, but for us, if we don’t get pregnant, it comes back, so we’re encouraged to take coltfriends and ah… well, you get the picture.”

“Does that mean you’re…” Twilight’s eyes shifted to Sunset’s belly.

Sunset snorted.

“Hardly! I take a Brew of Barrenness before my sessions. No pregnancy, so it comes back, but then my coltfriend and I knock it out again.”

“Oh.”

She kicked one of her back hooves awkwardly.

Wait… I know that look… Sunset thought.

Twilight looked deeply embarrassed by something, but she clearly looked like there was something she wanted to ask. She recognized it from the way she had felt when she had wanted to ask Shining if he wanted to help her out.

“Do you… want to join?” she chanced. “I did promise my coltfriend something special. He could help you beat your heat and then you wouldn’t have to worry about it again till next year.”

“I…”

To her credit, she didn’t blush any further. Rather, she almost looked relieved that she wasn’t the one to suggest it.

“I-I’ve never done it before--”

“I don’t think that would be a problem,” Sunset assured her. “You don’t have to. I just thought I’d offer.”

“Y-you’d let me join you and your coltfriend in…” she broke off, unable to get the word out.

“Sex,” Sunset finished, trying not to show her amusement.

“...s-sex, even though we only just m-met, just to help me beat my heat? Even though it’d be my f-first time?”

“Yeah,” Sunset nodded. “Like I said, you don’t have to. Just thought I’d offer.”

“I’ll d-do it.”

Yes!Shining, you are going to love this.

Sunset smiled sweetly at her. “Alright. I was planning on doing it tonight, is that alright?”

“The sooner we can beat it, th-the better.”

“Perfect,” Sunset nodded to herself, satisfied. “In that case, do you know where the Dusk Quarters are in the Residential Wing?” When Twilight nodded, she continued, “Be there at 6:30 tonight. I’ll take care of everything. In the meantime, I suggest drinking plenty of water. You need to rehydrate yourself after the last couple of weeks.”

“A-alright. 6:30 tonight, Dusk Quarters,” she recited.

“Yep. See you tonight, Twilight. I promise, you’ll love it.”

Shining hummed to himself as he trotted through the castle halls, making his way to Sunset’s room. Finally, the weekend! he rejoiced. No more having to worry about Sergeant Grit for a good few days, and there were two and a half whole days to spend with Sunset.

Another letter had been waiting for him at his barracks bed when they had gotten off. He had showered with his squadmates before he read it, but once he had, he was off.

Shining Armor,

Your presence is requested in the Dusk Quarters at 7:00 PM sharp. Come alone, and bring plenty of stamina.

--S

He hadn’t been all that tired after their training session today (Sergeant Grit had seemingly been going easy on them) but “bring plenty of stamina” was one of the few phrases in the Equestrian lexicon so powerful it could get a lame pony to walk again, and it had propelled him to the Residential Wing in record time.

Hopefully this would make up for the last few days. Ever since Cadance had gotten back, Shining could sense that Sunset had been off. The few times they had run into Cadance, no scene had been made, Cadance had excused herself cordially, and nothing had happened, but Sunset always seemed a bit insecure after.

Hopefully with this weekend, they could make progress toward getting rid of that insecurity. Though he could hardly blame her. If he had found out that she had dated some alicorn prince in the past, only to find that said alicorn didn’t think it was over and definitely wouldn’t just get over it immediately, he’d probably be a bit on the nervous side every time said Prince Charming ever showed up.

I mean, for starters, Prince Charming was an alicorn. If Sunset were in his position and told her squadmates that she was now caught between a regular old unicorn like him and the alicorn prince they had all seen smooch her, and that she preferred the unicorn, they’d probably laugh her out of the room.

Plus, Prince Charming was the Prince of Love, so he was always going to be better than Shining when it came to these things.

Then there was the obvious issue that Prince Charming and Sunset had no shortage of unresolved history, and they clearly were not over each other, and it still hurt just a bit every time Sunset saw Prince Charming, even before he gave a courteous smile and found his way out before she could even go talk to her and try to set things right...

“Sunset” sighed to himself. While it was definitely too late to go back to a regular old relationship with Cadance, and that was without even considering his new marefriend, he at least had hoped they could have remained friends. Maybe Cadance just needed some space for a while?

But then he came to and realized, he had walked clear past Sunset’s door and was now standing in front of the door to Princess Celestia’s room. At least, he thought it was Princess Celestia’s room. Why did she have to have a door that looked like everyone else’s?

With a groan, he turned around and practically galloped back to Sunset’s room. And once there, he took a moment to collect himself, raised a hoof, and knocked.

“Oh, he’s here,” he heard Sunset say, and he could feel his heart quicken at that. Had she gotten another mare? “Are you ready?”

Whoever the other pony in the room was must have nodded, because the door was bathed in the red glow of Sunset’s magic, and was opened up to allow him entry. Before it was even properly open, he gently pushed it himself and stepped in.

There they were, both on his bed, flanks faced toward him with their tails held aloft. Sunset, with her golden-streaked red mane, was wrapped up in red ribbon like a large birthday present, and was keeping her face determinedly forward, no doubt giving him a moment to appreciate his prize.

And then his eyes turned to the other mare, also adorned in the red ribbon, and--

“TWILY!?” he shouted in shock as the memory of her rump displaying her mare bits for the whole world to see burned itself into his brain and making him wish that he had as much brain bleach as could be found in the world.

He heard her gasp and saw her whirl around, mercifully removing that particular part of her anatomy from his gaze.

It was definitely her. He had just gotten an eyeful of his sister’s vagina.

No, scratch that, he had gotten an eyeful of his sister’s vagina, and Little Shining had dropped.

“Shiny!?” Twilight gasped and scrambled backward on the bed, almost kicking Sunset in the face as she looked over, confused by the sudden exclamations. Once at the back of Sunset’s bed, she seemed to almost try to press herself through the back, her face redder than Sunset's hair.

“What are you doing here!?” Shining asked, desperately hoping his boner would go away.

“Sh-she asked me here!” Twilight jabbed a hoof at Sunset “Said her coltfriend was going to--”

Her eyes widened.

“You’re dating her!?” she looked back and forth between them at lightning speed.

“Wait, you two know each other?” Now it was Sunset’s turn to look between the two of them in confusion.

“Yeah, she’s my sister.”
“Yeah, he’s my brother.”

“A-- ooooh,” a look of sheepish horror crossed her face. “Shit.”

“You didn’t tell me you had a marefriend!” Twilight’s embarrassment had disappeared and now she was getting off the bed to glare at him.

“I would have told you if I ever saw you!” Shining defended himself. “I haven’t seen you around in nearly three weeks! You missed our last two O’n’O sessions!”

She went red again and Shining didn’t miss how her tail suddenly flicked downward to cover her marehood up.

“I… I was in my tower the whole time…” she admitted, looking at the ground to hide her face. “M-my heat…”

Understanding flooded through Shining. “Ooooh. Right. Sunbutt heat.”

“S-Sunbutt heat?” snorted Sunset from her spot. “I like that. I’m gonna have to use it.”

“You didn’t know she was my sister?” Shining asked her, giving her a look that had “Really?” etched in every square inch.

“She never said anything about having a brother,” Sunset threw up her hooves defensively. “She said she was having trouble with her heat, asked me if I knew of a way to help her deal with it, and this was what I came up with! I told you I wanted it to be something special and this seemed like a good idea!”

“Just randomly propositioning mares for threesomes?” Shining asked, conveniently not mentioning Rainbow Dash propositioning him some time ago.

“Shining, trust me, if you could see how miserable she looked and smell how her tower smelled, you’d ask to help out just out of pity.”

“Wait,” Shining looked over at his sister, who was still blushing. It had now gotten even darker than the red in Sunset’s hair, and was now approaching the shade of red Sergeant Grit had when he was particularly pissed off. “How bad was it?”

“Y-you don’t want to kn-know,” Twilight stammered, turning her face away again.

“Take my word for it, Shining,” Sunset said, “she was miserable. That’s why I thought we could help her out.”

It was at that time that his mind decided to betray him. At the phrase “help her out,” his mind decided to feed him an image of Twilight on her back, in Sunset’s bed, with his cock pounding in and out of her at top speed.

The earlier image of her showing off her marehood wasn’t helping things, and Little Shining regaining his erect-ness

“Et tu?” he whispered, glaring underneath himself at his stallionhood, which seemed to bob as if to say “Fuck you, and fuck her already.”

“Outside of your cutie marks, you two don’t look much alike,” Sunset observed. “Are you two adopted? Because if you’re not biologically related, then technically it’s okay. And it’ll make it easier for you to take your mind off of… you know.”

“N-no,” Twilight answered, sighing. “We’re biological siblings. S-sorry, I ruined tonight…”

“No, no you didn’t ruin it!” Sunset assured her, jumping down to head her off before she could head for the door. “It’s my bad. I didn’t make sure you weren't his sister. I, uhh, let my hormones do my thinking for me to deal with the heat. Not to mention, I suppose I could have mentioned the name of my coltfriend at least once...”

At the mention of her heat, Twilight’s head drooped. “R-right. Guess I’ll just h-have to deal with it for a f-few more days.”

“No.”

Twilight’s head snapped up, and Sunset’ looked over her shoulder to Shining, surprise on both of their faces.

“Sh-Shining?” Twilight asked, confused. “No what?”

Shining swallowed. If what Sunset said was true-- and knowing her, it probably was-- his big brother instinct was taking over. And even though everything was telling him that this was a bad idea, he suddenly didn’t really care too much how Twilight was related to him.

She needed help. And he was going to do his damnedest to help her. And the mental images of himself and Twilight that seemed to be stuck on loop in his brain had absolutely nothing to do with that, no siree.

“I’ll do it.”

Sunset and Twilight just stared at him for a long moment. Shining couldn’t deny, the whole situation looked kind of ridiculous, since they were both still wearing the ribbon, but the situation Twilight was in didn’t really seem all that funny.

“Are… are you sure?” Sunset asked, looking at Twilight as she said that.

“Positive,” Shining dipped his head. “That is, if…” he trailed off to also glance at Twilight, who was chewing on her lip nervously, her face now probably inspiring its own shade of crayon color.

“I… I…”

“How about this, Twilight?” Sunset stepped between them while they just continued to stare into each others eyes, both of them with massive amounts of insecurity and indecision. “How about Shining and I go, and you watch to start off?”

Twilight’s eyes never left his, but she did seem to consider it.

“That way,” continued Sunset, “if you get into it and want to join in, you can.”

Twilight’s eyes shifted uncertainly to Sunset and back. But it was then that Shining noticed he was still standing in the door, and had been ever since he had realized that Twilight was the one in bed.

“Twily,” he said, stepping aside, to allow her out, “if you want, you can leave, and we’ll never mention this again. This never happened. But if you want to stay, I’ll help you out with your heat.”

“We’ll help you,” corrected Sunset, trotting over to stand next to him. ”I stand by what I said earlier, Twilight. We apprentices look out for each other.”

As Twilight continued to glance between the two of them nervously, Shining took the time to really survey her. It was always so strange, but having grown up around her, he had always taken her appearance for granted, if that made any sense. But now that they were older, now that he was a fully-grown stallion living on his own, and she now that was becoming a mare, he was finally able to see her for what she was.

And she was, in Shining’s humble opinion, beautiful!

Maybe it was whatever Sunset had done to help her prepare, but he had never really appreciated just how grown up his sister was, although that was partially to do with being around the future Alicorn of Love and thus his standards had been high.

Not to mention, she was, you know, his sister.

But now, he could appreciate that gorgeous shade of purple in her eyes, the simple yet elegant beauty in her mane, and how she was pleasingly skinny, but not in a skeletal way.

And oh shit, she had noticed he was checking her out.

“Sh-shining…?” she asked, glancing at the door. “C-close the door.”

As you wish, he thought, smiling to himself.

The door was bathed in pink and gently closed, before latching shut as well. As soon as it was closed, Sunset’s horn shone red, and a wave of magic flew out of her horn and coated the walls, molding to their shape, and then disappearing.

“Soundproofing charm,” she said, before trotting back to her bed and climbing on. “I think we’re going to need it tonight.”

Twilight’s uncertain gaze fell on Shining again as he trotted after his marefriend to climb up into the bed as well.

“I don’t…” Twilight mumbled, before taking a couple of tentative steps toward them.

“It’s fine, Twilight, it’s fine,” Sunset smiled gently. “There’s no pressure. If you would like to wait a bit, maybe watch Shining and I first until you feel comfortable joining in, that’s perfectly okay.”

“S-sure,” Twilight said, climbing up onto the tail end of the bed, whereas Shining and Sunset were more at the head of it.

That was all they needed to hear.

With that, Shining and Sunset caught each others’ eyes, and after a pause to appreciate the moment, they kissed.

As with every time he kissed Sunset, fireworks were exploding in his mind, and the connection they shared was almost as good as sex itself.

This is never going to get old…

It didn’t take long for Sunset to deepen the kiss, pushing into him and poking her tongue within his mouth. Rather eagerly, he opened his own mouth and sent his own tongue forth to meet hers in glorious combat! It was like every movie sword fight he had ever seen, with stabs, parries, and a gentle ebb and flow as one minute he was in control, and the next he had retreated and she had taken over.

But before long, she pushed in just hard enough to cause him to tumble backward, landing softly on the pillows with her on top, her mane falling around his face and tickling him lightly.

And at the back of his mind, he knew that Little Shining had to be standing tall, in full view of Twilight.

That thought alone made him smile. The absurdity of their situation was still very much there. Here he was, making out with his mare, with his stallionhood on full display while his sister watched.

Or so he believed.

All too soon, Sunset broke the kiss, but not before giving his lower lip one last nibble. Then, she leaned up to his ear and nibbled his earlobe, and then, she began to slide her way up him.

He could feel the heat of her marehood as it drew closer, leaving faint kisses on his coat and leaving the places it touched with just a dab of her essence, as she drew it closer and closer. Just as she had gotten up to his chest, she lifted herself up, finally giving Shining a view of his sister where she sat.

Indeed, Little Shining was standing tall for her, but her eyes were fixed elsewhere, past it. They were focused, with total attention, on Sunset’s marehood, but for the brief moment they flicked downward to look at him. And Shining could see that she was starting to breathe rather heavily.

A glance downward revealed that her vagina had grown very wet, and was leaving a spot under her.

And then she was gone, obscured by Sunset’s mound as it came down right at his chin. A glance upward showed that Sunset had her head raised skyward, and her eyes closed, ready and waiting.

And who was he to disappoint her?

Raising his own hooves up to her flanks, he pulled her just a bit more forward, and now she sat right on his muzzle, in perfect position.

As before, it began with a kiss, with Shining’s lips applied liberally to her lower ones, paying extra attention to her clit.

Thank-you for being patient with me, he thought of Sunset. Thank-you for teaching me this stuff.

And, like the earlier kiss, next came the tongue, pushing its way in, and beginning the battle anew. His opponent wasn’t there this time, but that didn’t stop him from sliding his tongue around just as before, licking up the essence that coated her walls and causing Sunset to moan above him.

While he was still far from perfect, and no doubt her heat was playing a factor in how much she enjoyed this, Shining had learned from their previous two encounters. He had learned the spots Sunset liked, and he had learned when best to go for her clit. He still hadn’t really gotten used to using his tongue like this, so it did tire out somewhat quickly, but as with their earlier make-out, ebb and flow were his friends.

Her thighs squeezed his head, and he smiled into her pussy. It had taken a couple of minutes to get her twitching, last time. Now, it couldn’t have been more than half that time. Either he was getting good at this…

Or maybe she likes being watched…

That thought didn’t kill any sense of progress, but it did motivate him even more.

Kinky mare… he thought. What else do you have in store for me?

He felt something warm envelop his dick, suddenly. It didn’t go very far down, but it was definitely noticeable. The suddenness of the action caught him off-guard, but he appreciated it all the same.

Wait a minute… he thought.

The warm thing pushed down even further, without even coming up, or using tongue. That definitely wasn’t Sunset. She wasn't this crude. In hindsight, Sunset was facing away from his dick anyway!

“TW--!” he shouted in shock as he could feel her throat muscles clench, gagging as she tried to force his rod down her throat.

Most of it was muffled, but Sunset got the message, lifting herself off of him and turning around to see her younger counterpart doing her damnedest to force Shining’s cock as far down as she could.

“Twilight! Twilight, stop!” Sunset gently pushed her back. As soon as his dick came loose, she started sputtering. “Deep breaths, deep breaths,” Sunset instructed, rubbing her back.

“S-sorry,” Twilight cringed as she saw Shining look down at her. “I-I just thought I c-could--”

“Twilight, honey, it’s okay,” Sunset soothed, forcing herself not to laugh. Twilight’s nervousness was rather endearing, Shining did have to admit.

“Yeah, it wasn’t… too bad,” he said, trying his best to help Sunset.

Sunset just gave him a flat look that said, in no uncertain terms, “You’re not helping!”

“I mean,” he changed course, “it surprised me but... “

“Twilight, ignore your brother,” Sunset chose to hug the younger mare instead. “You just need some practice, is all. Don’t try to do more than you’re able to or comfortable with.”

“O-okay,” she still wasn’t meeting his eyes.

“Here,” Shining slid forward. “How about you lie on your back?”

Sunset nodded at that, releasing the mare and gently easing her onto her back as Shining suggested it. Twilight didn’t resist, but she did try to cover up as she watched the both of them look down at her.

“It’s okay, it’s okay,” Sunset stroked her mane with the touch of a feather. “There’s no need to hide from us.”

Sunset indicated a dresser with her head, on which were a couple of empty potion vials, and a third that still had a potion in it, which was purple in color.

“Shining, be a dear and drink that, would you?”

Shining nodded, getting up from the bed, grabbing the vial, and draining it in one gulp.

Mmm, grape flavor, he thought. And not that awful medicine kind, either!

“What is this?” he asked, placing the vial back atop the dresser, next to the other ones. Meanwhile, Sunset and Twilight were divesting themselves of the ribbon, which Sunset casually tossed into a nearby rubbish bin.

“The other two were Brews of Barrenness,” answered Sunset, resuming her stroking, which was easing Twilight quite well. She had relaxed her lower legs, and Sunset was gliding a hoof along her belly, no doubt looking to warm her up before she turned Twilight over to him. “Don’t want any unexpected side-effects resulting from tonight’s activities, do we?”

The thought of a pair of children, one of his with Sunset and one of his with Twilight, filled his mind, though it was far from unpleasant. Unfortunately, he knew she was right.

“I guess not,” he shook his head. “What about mine?”

“A neutralized Philter of Fertility,” Sunset answered cheerfully. “Normally an aphrodisiac coupled with a sperm production enhancement mixture, I took the aphrodisiac properties out of it. Now it’ll just make sure you have plenty of ‘juice’ for the both of us.”

Shining grinned at that, and practically jumped back on the bed, landing right where he had been before.

Twilight looked down her body at him as he got down on his belly between her legs. There was pure desire in her eyes, coupled with a strange neediness.

She wants this! he realized. How long had she wanted it? Did this mean that deep down, she had fantasized about him? He would have been ashamed to admit before that he had spent a couple of nights fapping to her. It always left him feeling a lot more shameful than his usual sessions. But now that they were here?

Now, he didn’t care. She wanted it, he wanted it, and she was going to get it.

“Ready?” he asked, slowly prying her legs apart and revealing her treasure for him to see. It really was perfect. Puffy and very damp, clearly due to her heat and arousal, but it made him want to jump right in.

She nodded, her breath deepening as she lay her head back in anticipation.

As with Sunset, Shining started gently. After he got close and his breath tickled her marehood, she had shifted, so he knew she was going to be extra-sensitive tonight. The first thing he did was gently lick at her opening, causing her thighs to clench and her to let out a moan.

Shining smiled. She tasted sweet, like… grapes. Yes, the sweetness reminded him of grapes. Or maybe there was still some of that philter left over on his tongue, flavoring it. In any case, he wanted more.

He licked again, a bit more forcefully this time, and Twilight moaned again, a bit louder this time.

Where Sunset made noises for particularly pleasurable moments, Twilight seemed to be rather expressive in general. That or, again, the heat was just amplifying everything.

Still, he liked the sounds she made, and in a short time, his tongue had gone from licking outside to inside, and her yelps and moans had changed to reflect it.

Her essence was his nectar, her vagina his fountain, and lap and lap he did, never feeling tired of it. As with Sunset, he began to work his tongue inside of her, doing more than just licking aimlessly, and he was rewarded with Twilight suddenly crying out as he flicked at her clit.

Her sister, it turned out, liked to make noise. Not with words, but with sounds. Sunset would do the same, but far less frequently. Twilight, however, was a textbook screamer. When he would flick his tongue in a particularly-pleasing way, she would yelp. When he would hit one of her spots, she would exclaim. And when he sucked, she would gasp and hiss.

She was his instrument, he was her musician, and he played her. By the end of it, he wanted her to sing. And so, like he had with Sunset, he turned this act of intimacy into something resembling a dance, where he would go in, he would flick, twist, turn, lap, suck, and everything else he could think of, feeling her out and then going in when he knew he had hit a spot she liked. It didn’t take long at all before it never crossed his mind that it was his sister he was eating out. It was a beautiful mare, and she was making the most delightful noises.

“Sh-Shining!” Twilight yelped as she twitched. Shining took a moment to smile at the sound of his name, but then she cried out again, and that made him frown for just a moment. Was she faking it? he wondered, considering he hadn’t done anything to elicit that last cry, until he realized Sunset must be adding her own ministrations.

A quick glance up showed that this, indeed, was the case. She had taken to licking Twilight’s horn, the same way she did his cock. Her tongue glided along its spiralling length, before she took the end of it in her mouth and sucked.

Twilight almost screamed at that. Her back arched upward, pressing her sternum into the sky as far as it would go, and that only emboldened Shining to dive back in.

Their combined forces brought Twilight untold amounts of pleasure, and it was reflected in her howling and yelping. It only made Shining grin all the more when he felt her hooves push at the back of his head, urging him deeper.

The combination of their pleasuring doomed Twilight in mere moments. Just as he was certain she was nearing her peak, Shining felt himself be pushed back, much to his dismay, but the sight of why he was being pushed away proved this was the best course of action. Sunset had pushed him back, and she herself had retreated just a bit, using her hoof to stimulate Twilight’s horn.

Which was now glowing a bright magenta, the only warning Shining had of what was coming.

Or rather, who was coming.

With a scream of pleasure, Twilight spasmed on the bed, twisting and contorting in every direction her body would allow as the aura of magic spread to cover all of her. As soon as it had, Sunset withdrew her hoof quickly, slid up next to Shining, and just watched.

Once her entire body was glowing with her aura, Twilight came. With a scream, her thighs clenched shut, her twisting intensified, and her horn began to shoot a stream of stars that spiraled through the air before fading into nothingness. All while Shining and Sunset watched in awe.

Well, Shining mostly. Sunset looked satisfied by her handiwork, but not surprised.

“How’s that, Shining?” she asked, laying her head on his shoulder. “Fireworks.”

Shining snorted at that, but continued to enjoy the sounds of Twilight’s climax as she continued to writhe. It lasted several seconds, during which time Twilight’s cries would have alerted the entire castle but for Sunset’s earlier spell. It took some time, but eventually, Twilight’s glow faded, and she was left panting where she lay.

“Wh-what was…” she mumbled tiredly, “wh-what…?”

“Never had a hornjob before?” Sunset asked, scooting over and stroking her sweaty mane.

“Th-this is my first time doing anyth-thing like this,” she breathed, taking great gulps of air. “That w-was…”

“Pretty amazing, right?” Sunset asked, grinning. “I thought so. I’ve never had one done to me before,” she glanced back at Shining meaningfully, “but I’ve got time for that later. How do you feel?”

“W-wow,” was all Twilight could say to that, before a tired smile broke across her face.

“Deep breaths, Twilight,” advised Sunset, before leaning down and kissing her forehead. “Take a break. Feel free to rub yourself again while you get your energy back.”

As she rose up, she looked right at Shining with a predatory grin.

“But it’s my turn, now.”

Red magic covered him from head to hoof, lifted him into the air, and set him down where they had been a few minutes before. Sunset scooted toward him, giving Twilight plenty of room to breathe and recover, then turned her lower body toward him and flipped over on her back.

Shining drank every detail in. The way her mane was splayed on the bed, how she let her back legs fall sideways to reveal herself to him, and most especially how she drew her hooves down her body and spread herself just for him.

Little Shining certainly appreciated the quick show. It had to have been harder than diamonds by this point.

“Whenever you’re ready, Shining,” purred Sunset, fixing him with a half-lidded stare.

Shining grinned, and leaned forward to be on top of her. Their breath mixed as they locked eyes, her desire and anticipation just as evident as he figured his were.

He reached a hoof down to grasp his shaft, adjusting his head and leaning forward so that it pressed against her opening. When she felt it, she hissed, and he could sense her shift her legs further apart.

And then he pushed in.

Just like the last two times, she fit him like a glove. Or perhaps, he fit her. The wonderful wet warmth enveloped his head, and then began to continue to descend as he pushed further and further in. His medial ring took less effort to pass than before, and in a short time, he was hilted inside her, his hips resting comfortably against her’s.

“Aaah,” she sighed, letting her eyes drift shut as she adjusted herself once again to the feeling of him inside of her. “I missed this,” she smiled.

“Yeah,” Shining nodded, not sure what else to say.

She giggled a bit at that, reaching a hoof up to stroke his cheek, but when it came down, she began to push her hips into him, trying to get him going. He got the message.

With a slow, deliberate motion, he pulled back, even bringing his medial ring out, to leave just as much as he dared within her, and then he slammed himself forward, hard. A loud smack! filled the room, slightly muffled by their fur, as their hips collided.

“AH!” yelped Sunset, her eyes flying open from the suddenness of it, but she let them drift shut again as Shining began to establish a rhythm, pounding into her at top speed. His balls slapped against her butt as he hilted inside of her again and again, filling the air with the meaty slaps of their hips colliding, every few of them punctuated by a whimper from Sunset, or if he managed to hit just right, an outright cry.

Rather than simply leave his upper half to just sit there while his lower half did all the work, he took the opportunity to lick and suckle at her neck, with the occasional nip at her shoulder bone. She liked when he bit her ear lobe, but Shining had found a particularly sweet spot right at the crook of her neck and shoulder, and he intended to make liberal use of it.

Maybe he’d even leave a love bite this time, marking her as his mare for all the world to see.

The thought of her wearing such a mark added fuel to the fire that was his libido, and he sped up just enough for her to notice. As soon as he had gotten up to his new speed, she had wrapped her forehooves around his neck and held him there. Unfortunately, it was smushing his muzzle into her skin, which did make it a bit difficult to breathe, but a quick adjustment later, they were kissing with all the passion of their earlier moment.

Their tongues weren’t as coordinated this time around, so it was little more than jamming them together and rubbing them around to add to the moment, but it still made Shining swell inside.

She’s mine, he thought. Out of all the stallions in Equestria, she’s let herself be mine.

Too soon, it ended, but they did have to come up for air. And Sunset had been trying to hold in her coos and whimpers for the sake of their kiss. Shining, too, leaned back, so that he could watch her from above while he pounded into her, but a momentary curiosity overcame him, and he glanced over to Twilight.

She had her back propped up against the footboard of Sunset’s bed, her mouth was parted as she watched them, and her hoof was sliding up and down her folds.

She’s really getting into this, he thought, returning his attention to Sunset beneath him. I can’t wait for her turn.

But first, the mare beneath him.

“F-fuck,” Sunset grunted. Shining could see the warnings of an orgasm starting to appear on her face. She was biting her lip, her face was scrunched up, and she was leaning her head back and arching her chest into the air.

“Almost… there?” Shining breathed, leaning down to say it right into her ear.

She nodded. “C-close…”

As she said that, he could feel the warning signs of an orgasm of his own approaching. The subtle feeling of pressure starting to mount.

“M-me too,” he gasped, leaning back just enough to plant little kisses along her jaw, which only encouraged her to bare more of her neck for him.

“Ah, OH!” Sunset exclaimed, and he could feel it coming. Her walls were clamping down on him, trying to milk him for all he was worth.

“S-Sunny!” he shouted, feeling the pressure reach its peak.

“SHINING!” Sunset cried, grabbing his neck again and pulling him in for a kiss, just as they climaxed, her legs hooking themselves around his hips as he gave one final thrust, pushing his flaring head as deep within her as he could, and released.

Their last session had been a little over a week ago, so he was a bit on the pent-up side, and he was sure that the philter he had drunk was doing its part as well. He released spurt after spurt of his seed within her, continuing to rock his hips as he eked every last bit from his balls. He wanted to fill her. He wanted her so full, it dripped out of her while they slept.

After several seconds of bliss, Shining felt himself give one last contraction, and then he let himself down on top of her, to which she responded by curling her front hooves around him to hold him close, almost like what he had done to her in the bathtub.

“Aah,” he sighed, resting his chin on her shoulder.

“Tired?” she asked, the word slurring ever so slightly in her afterglow.

“Yeah,” Shining sighed. “Just need a minute to… rest.”

“I gotcha,” she replied, before craning her neck just a bit. “How about you?”

Shining looked up and over, where his sister was rubbing rather furiously at this point, her face scrunched up.

“Think she liked it,” Shining observed.

Sunset frowned for a moment. With a quick flash of red light, Twilight’s hoof was pulled away from her folds, much to her dismay.

“Wha-hey!” Twilight exclaimed, giving her an irritated look.

“Your turn,” Sunset said, reaching between them to push Shining off of her. As he felt his cock, which was still erect (no doubt due to the philter), slide free of her depths, he glanced down just in time to see a small stream of his semen start to trickle out of her and into her tail.

Twilight saw it too, and Shining could hear her draw a sharp breath of air in.

Relax, he thought, amused. Probably gonna be nowhere near that much.

"Here, lie back,” she leaned up to guide him down onto his back, with her less than a yard away. Twilight, however, had flipped onto her belly and was crawling toward him, her eyes glazed over and fixed on his cock and a hungry look on her face.

But before she got to him, she diverted course. With a rather quick movement, she leaned down and licked up some of his seed that was dripping from Sunset’s hole.

Shining felt his jaw drop.

Sunset’s legs twitched, but she made no effort to stop Twilight as the younger mare licked up a good amount of the dripping cum…

...and then swallowed.

If Shining’s cock wasn’t erect before, it sure was now.

“How does it taste?” Sunset asked.

Twilight responded by leaning back over and licking every last bit of his cock, cleaning it of the smeared cum from the both of them.

“Enjoying this, S-Sunny?” Shining asked as one of his own legs twitched when Twilight managed to get a reaction out of him with a forceful lick of his sensitive head. She definitely was going to need some work on her mouth technique. Perhaps, if Sunset was up for it, they could invite her back…?

“So hot,” Sunset breathed, grinning. That’s probably as close to a Yes as anything.

As soon as it had been licked to her satisfaction, Twilight finally retreated. And now it was time for her main event.

She was watching his cock, standing there, waiting for her. Unlike Sunset, who had eagerly gotten going, Twilight was staring at it with a large amount of trepidation.

“You alright, Twily?” he asked, feeling concern wash over him.

“I-I’m n-nervous,” she admitted, bowing her head to hide her face from him. “I-it hurts the f-first time, right?”

“Just the first time,” assured Sunset, nodding. “If it’s too much, just stop and wait, alright? Don’t hurt yourself.”

Twilight nodded, her breath getting heavier and more laborious. And then she started to crawl forward, her undercarriage brushing his cock as she went, until the two of them were within inches. She, however, was still looking back, as her magic enveloped his sensitive stallionhood.

“Ooh,” he cooed, as her warm aura covered his shaft and placed his tip right against her folds. He could feel the heat radiating off of them, and no sooner had she touched him than he had felt a trickle of moisture slide down his length.

Once she was in position, she turned to look him in the eyes again. His blue met her purple, and so much was exchanged in one glance. The nervousness, the desire, the anticipation…

And then she began to slowly work her way backward, sliding down onto him.

“A-ah,” Twilight moaned as she pushed her way down his length.

Good Faust above, she is tight!

It couldn’t have been more obvious that this was her first time. She felt much tighter than Sunset had, and it seemed to be taking more effort for Twilight to push her way in than it had Sunset.

Of course, Twilight was five years younger than him, and a couple of years younger than Sunset, and she wasn’t quite fully grown yet, so it was to be expected.

And then he felt a blockage. He hadn’t even gotten a full inch in yet, which left zero doubt for what it was.

The nervousness intensified in Twilight’s eyes, but Shining pulled her forehead down to his to press his against her own, letting her know he was right here, and that he would never hurt her.

She took a deep breath in, and then pushed.

“A-AH!” Twilight screamed, her eyes clenching shut and her legs faltering under her. Quick as he could Shining sat up a bit and caught her, thankfully only barely moving his shaft with all of the shifting. He held her in his arms, kissing away the tears as she winced and quivered from the pain. He didn’t care how long it would take, all that mattered was that Twilight was in pain, and he was going to be there for her until it had passed.

Sunset, meanwhile sidled over to lay down next to him while he held Twilight. Like him, her focus was on her younger counterpart.

“You okay, Twilight?” she asked gently.

Twilight, whose face was still screwed up in pain, nodded, before a tremor wracked her and she let out a quiet sob of pain.

“You don’t have to do this tonight,” Sunset said, her red magic conjuring a tissue to mop up the trickle of blood that had issued from her broken hymen. “If it’s too much, I have something for the pain--”

“No!” Twilight cried, her breathing just as labored as it had been before she had given Shining her virginity. “No, I want this,” she growled, gritting her teeth as she tried to fight her way through the pain. “I want this!”

Shining and Sunset exchanged a glance, but did nothing to stop her. She was pushing herself up and out of Shining’s grasp, slowly taking control again.

“Are… are you sure?” he asked her. “I… you know I’d never hurt you.”

“Shining,” Twilight said in a weak voice, bracing her front hooves against the bed. And then she pushed back again. “I w-want this.”

Shining groaned as he felt more of his shaft push into her, reaching deeper and deeper inside at an agonizing rate. Twilight just continued to push, trying to take as much of him as she could, before she finally came to rest against his medial ring.

“Don’t force yourself,” advised Sunset. “You’re young and still growing, so you aren’t going to be able to take as much as me. Don’t take more than you’re capable of.”

But Twilight seemed heedless to Sunset’s advice, instead pushing herself even harder, until Shining’s medial ring finally slipped inside.

“Mmph!” Shining grunted as it did, and Twilight continued to push herself downward, until finally, after a few more seconds, he felt himself push up against her deepest barrier. There were still roughly two inches to go for him, but he was impressed that Twilight, young as she was, could take this much. He could hilt himself inside of Sunset, as demonstrated only a few minutes ago, but he was sure there was still a bit of room to spare. With Twilight, however, assuming they did this again, he was certain she’d be able to fit all of him in a few years.

But Twilight still didn’t stop. She continued to try and force him deeper, trying to fit those last bits inside of her, despite the obvious pain on her face.

“Twilight, stop,” Shining reached out and grasped both of her front hooves in his before she could hurt herself. “I’m in as far as I’m going to be able to go.”

“No,” she shook her head. He could see that she had grit her teeth, and she was continuing to try to push her hips into his. “I can… I will…”

“Twilight, stop,” Shining finally flipped her onto her back so that he was the one in control. “If you keep going, you’re going to hurt yourself.”

Sunset leaned onto her side and stroked Twilight’s mane as she lay there. She really seemed to like doing that, he noticed. “Twilight, trust me, you don’t have to take all of Shining to be able to enjoy him.”

“But I w-want to,” Twilight insisted. “I want to m-make him feel good.”

“Sis,” Shining reached a hoof down to cup her cheek, “come on. With all your reading, I’d have thought someone would have mentioned that it’s not about how much you can take. It’s about who you’re sharing the moment with.”

Twilight finally relaxed against the pillows as he said that. “O-okay,” she replied nervously, looking down herself to the spot where they were joined. “I just… I w-wanted to make you f-feel as good as Sunset did.”

“Twilight, honey,” Sunset managed to contain a giggle, “I have practice. Don’t try to copy what I can do. Try to focus on what you can do that I can’t. I know you probably don’t know just what you can do, but…”

Her eyes flicked toward Shining for the briefest moment.

“Be you. Not me.”

“Sunny’s right, Twily,” Shining gave pulled back and gave a light thrust to punctuate the point. Twilight made possibly the softest “Ah,” that had ever been recorded, which only reinforced his point.

“I… I’ll try,” Twilight promised, though the omnipresent nervousness was there, naturally.

“How would you like me to go?” Shining asked, patiently refraining from any more thrusting until he knew what she wanted.

“Start… slowly,” Twilight answered, her eyes still glued to their conjoined nethers. “And….”

“And?” Shining pressed.

“Lean over me,” she finished, looking away again. “like… like you did with her.”

“Twilight, there’s nothing to be embarrassed about,” Sunset assured her, smiling sweetly. “Really, you can trust us with anything you find you like.”

Shining didn’t add anything to that. Instead, he did as asked, leaning his upper body down, settling over her just as he had with Sunset, with his front hooves resting on either side of her barrel, and his head low enough to where their breath mixed.

“Like this?” he asked.

Twilight nodded, returning her gaze to his own. “Y-yes. Just like this.”

Shining smiled reassuringly at her, and then, just like before, withdrew just a bit and then pushed back in.

“Aaah,” Twilight sighed, letting her eyes drift shut. “Yeah, like that.”

So he obliged. He would withdraw slowly, taking just a bit more each time, and then just as slowly, push back in. Every thrust caused her to let out some sort of moan or sigh.. If this was how she sounded now, when he was controlling himself and going this slow, how was she going to sound when he picked up?

Unfortunately, things were thrown off when she tried to buck her hips into his in time. It didn’t kill the moment, but it certainly made thrusting a bit harder when he tried to go in but she would pull back and then push back in irregularly.

“Twilight,” Shining stuck a hoof on her sternum rather firmly to get her attention.

"I… am I doing s-something wrong?” Twilight asked, and Shining was alarmed to see that she looked scared again. Not nervous, like the last few times, but actually scared.

“Stop trying to push back,” Shining replied, as gently as he could. “You’re not in trouble. this isn’t being graded or anything, but let me do all the work, alright? You’re new to this and I want it to be as amazing for you as it is for me and Sunny.”

“I’m s-sorry,” Twilight looked away again, cringing at herself. “I just… I know first times are supposed to be awkw-ward, but I w-wanted to make you feel as good as you’re making me feel and it’s n-not working and…”

And unfortunately for Shining, she was off on one of her patented apocalyptic scenarios. Usually the only way to shake her out of them was with something a bit drastic, and he had just the thing.

Though will Sunny like it? he thought, giving her a glance.

She noticed. “What?” she asked, confused by his look.

“Sorry about this,” he said.

“Sorry about what?”

But Shining didn’t answer that. Instead, he simply reached a hoof around, turned his sister’s face toward him, and before she could react, he leaned down and kissed her right on the lips.

It wasn’t anything spectacular. He just needed something to calm her down, and the few moments of surprise granted by this would hopefully do it. Satisfied that he had stopped her, he started to pull back.

But he hadn’t even gone two inches when he felt her hooves take hold of his face and pull him back down, kissing him right back. And unlike his kiss, which had just been a simple plant of the lips, hers were moving.

She… she really likes this, Shining thought, feeling his eyelids drift shut, and beginning to return the kiss.

It felt like the first few times he and Cadance had kissed, when all they did was just work each others’ lips, but he had a feeling that it didn’t matter to Twilight. She even proved most receptive when he finally poked at her lips with his tongue, opening up and beginning the dance. Once that happened, he started to thrust again, which added hums to the mix.

If he were honest with himself, she definitely needed work here too. The entire area around his mouth was covered with her saliva in seconds as she continued to deepen their kiss, and her tongue was just sort of being thrust into his mouth and rubbed against his own.

She’ll learn, he thought, before letting his mind go blank again as he picked up pace.

After several blissful moments, they finally broke apart when Shining hit a spot inside of her that finally made Twilight cry out.

But when she tried to resume the kiss, she accidentally brushed his horn with her own. And, like it had when Sunset had stimulated it, it triggered her climax.

“AH! AAAAAH!” she screamed, tensing up and glowing once more. Her eyes clenched shut, her face screwed up, and her breast arched toward the ceiling. Within her passage, her walls were now clamping down on his cock, and her spasming legs were squeezing it even tighter every half-second.

And Shining could feel it now. The pressure he had felt earlier with Sunset was back, and it seemed to be coming even more powerfully than before.

“Shining!” Sunset exclaimed, reaching out to try and pull him back, but he had crossed the point of no return and there was no way of backing him off safely.

As Twilight’s horn began to shoot off stars while she writhed beneath him, Shining continued to thrust, feeling them grow more and more erratic as he teetered on the edge.

“Twilight!” he finally cried out, his cock flaring as he let loose inside of her in what felt like the single most powerful orgasm he had ever experienced.

Every stream of stars that issued from her horn coincided with a spurt of his seed within her. It felt like it had to have lasted an endless amount of minutes. His orgasm just seemed to stretch on and on as he sent rope after rope into her waiting womb…

Until he could feel it dying down as he finally reached empty, thrusting a few more weak times and pushing out just a trickle or two more of his semen. Underneath him, Twilight was still in the throes of her own climax, her face still completely screwed up as the orgasmic bliss continued to ravage her, and her horn continued to shoot stars.

Without pausing to consider his own safety, Shining leaned back down and kissed her once more. thrusting his tongue to meet her own without waiting, and caressing it gently as she reflexively clutched at his back.

This moment… this wonderful moment… it felt no different from the times he and Sunset kissed during their sessions. The same passion was there, and deep down… deep down, Shining could feel that same feeling. That same… whatever it was that had been there with Cadance and was there with Sunset.

And all too soon, she came down.

As she did, he separated from her to give her some breathing room, though she did try to chase him like before. However, unlike last time, he didn’t try to go any further, and just rested his forehead against her own and let their breath mix as they both took great gulps of air.

“So, how was it?” came Sunset’s voice from his left.

Twilight didn’t say anything. Or perhaps she couldn’t. She was completely and utterly exhausted, her mane with a light glisten from the sweat within it, and her eyes barely staying open.

“Did you enjoy it?” Sunset asked again. To that, Twilight managed a weak nod.

“I definitely enjoyed watching you two,” Sunset stroked Twilight’s mane with a hoof. “And if you want, I’m definitely okay with doing this again.”

“I… think… I’d like that,” Twilight managed with a slight whimper as Shining shifted beneath her, his cock still buried inside her.

“Welp, you’re clearly exhausted, and I’m a little on the tired side myself,” Sunset slid herself under the covers of her bed and held up an opening for them as well. “How about we end the evening with a nice long sleep?”

Twilight nodded again, and Shining took that as his signal to start pulling out of her--

“W-wait!” one of her hooves caught his own, stopping him.

“Twily?” he asked, pausing before he could extract himself.

“C-could I…” her blush, still present from the last several minutes, deepend somewhat. Shining, however, caught her meaning.

Sliding his hooves under her shoulders, he scooped her up into his arms, flipped them around so that he was on his back and she was resting on his belly, and then managed to slide them both into the waiting opening in the bed’s comforter.

“Aww, you two look just adorable like that,” cooed Sunset.

Shining let out a tired chuckle, but Twilight, it seemed, was letting herself fall asleep without waiting.

“Let me get the lights,” Sunset said, her red magic dimming all of the artificial light fixtures in the room.

As soon as the room went dark, Shining relaxed his head into the pillow behind him. What a night, he thought. Who’d have thought an hour ago that he’d have had a threesome with his marefriend and his sister?

Or more, that he had enjoyed being with his sister just as much as he had with Sunset?

With that thought in mind, he leaned up and kissed Twilight’s forehead through her mane. Just a little gesture of affection. He was with Sunset; if Twilight wanted to do more of this, he was very okay with it.

Though they’d have to be careful considering how quickly rumors could spread and how devastating an impact they could have in the capital of Equestrian culture. Still, they’d worry about that later.

“Love you, Shining,” Twilight mumbled sleepily, so quietly he was almost sure he didn’t hear it, before he felt her head rest on his ribs.

With one last smile to himself, he draped an arm around Twilight, leaned his head sideways to touch Sunset’s and let sleep overtake him.
