Spike’s after wedding bachelor party was in full swing.
While the timing was a bit off, Twilight was impressed by just how much Spike had managed to throw together without a lot of time. He had secured a whole section of the Canterlot castle from Princess Celestia and had gathered friends and celebrities from all over Equestria. DJ-P0N3 had been brought for an encore show after the wedding, Princess Luna was busy in a drinking game with Rainbow Dash, and the chamber was filled with Shining Armor’s friends and wedding guests.
Despite her initial reservations, she had to admit that this post-wedding bachelor party was thus far a success. Everyone was in good spirits and after the changeling invasion, everypony looked like they were enjoying the chance to let loose and continue the celebrations after the wedding. She looked over the room contently, a job well done.
It was only when her eyes went to the bar that she noticed her brother, the newly minted husband to Princess Cadence was sitting alone, nursing a drink.
Considering this party was for him, Twilight wasn’t sure why Shining Armor was spending his time alone. With a frown, she moved to sit with him, “Bartender, a drink.”
Shining offer her a tired smile, “Twily, how are you enjoying the party? Spike certainly pulled out all the stops for this, huh?”
She nodded in agreement, “There was a lot of decorations and food leftover from the wedding and everypony was already in town, I think that did a lot of the work for him,” she eyed the window, watching as fireworks went off outside, exploding in the shapes of Shining’s cutie mark, “I think those are new.”
Shining snorted, taking a sip of his drink before speaking again, “Things are so moving so fast, little sis. I’m married! We saved Canterlot, and you saved Equestria not that long ago too. Twice! When did life get so complicated?”
“Exactly one year and one hundred and eighty two days ago,” Twilight said without batting an eye, “When Princess Celestia sent me to Ponyville.”
Shining smirked a bit, “Yeah, I guess that is true. That’s about when life started getting serious for me too, when I got promoted to Captain of the Guard. I guess I’m just a little overwhelmed by everything, you know?”
Twilight sipped her drink, “I remember my first time saving the world, I was a bundle of nerves for days!”
Shining Armor laughed, “Mom and Dad are so proud. They were proud enough, but to have two world-saving heroes in the family isn’t something most parents can say.”
Twilight had to agree with that, “I’m just glad that everything worked out.”
“Almost everything,” Shining agreed, taking another drink.
It was clear that something was on his mind, but she didn’t quite want to push yet. Sugarheart’s Suggestions For Sibling Support and Sentimentality wrote that one of the best ways to help was to listen. So deciding that it would be best to be patient and wait until he was ready to open up, she placed some bits down and bought the two of them more drinks.
One drink turned into two, and by the time she was working on her third drink, she was feeling far more relaxed. She had been to enough of Pinkie’s Late Night parties to develop at least some resistance to drinks. Any gloom that had been over her big brother best friend forever had been overtaken by excitement as the two talked.
“So, what was it like to have the power of love overtake you to create a spell powerful enough to blow all the changelings out of the city, but also focused enough to remove only changelings?” Twilight asked curiously, her gaze focused on her brother.
He chuckled, “Oh, well… It was kind of just instinct, you know? The city was under attack, my fiance was kidnapped, they had just captured you… I just,” he waved his hooves, “Sometimes magic just flows through you, you know?”
“All too well,” she smiled, thinking fondly back to the day where she was first accepted as Princess Celestia’s personal student. She quickly glanced at Spike, watching as he was cheerfully talking with a few of Shining’s old college friends.
Twilight returned to her drink, “You clearly love Cadence very much.”
“Not just Cadence…” Shining trailed off, “Twily, do you remember the old days? When we used to play house?”
She smiled warmly, “Of course! We played in the backyard or the park, I was the mom, you were the dad, and Spike was our baby. We’d spend hours outside playing, it was my favorite game!”
“Mine too,” Shining laughed, “I’ve been thinking a lot about those good old times lately. I’ll just spend nights in bed thinking about our childhoods, you know? Simpler days.”
Twilight nodded in understanding. Truth be told, she had been thinking about her brother a lot since getting the invitation to this wedding, “I know all too well,” she confirmed, times were so much simpler. Shining had been her only friend, her confidant, in many ways her entire world. If she just closed her eyes, she could just imagine being transported back to those windy spring days.
Shining put his drink down, “You want to get out of here for a bit? Nopony will notice if we step out for a few minutes.”
She didn’t need much convincing. When the two of them walked out of the door, they were completely unseen in the luminescence of the celebration.
Shining Armor led the two of them up the tower and to an empty room with wide windows showing the entire city and Equestria beyond. He chuckled a bit, “If you squint, I think you can see the park from here.”
Twilight considered this, “Well… Why not get a closer look?” Her horn glowed and with practiced ease she teleported the pair of them to the park, landing in the center of a grassy plain, empty of all ponies and leaving the pair alone.
She grinned a bit, “I’ve gotten a lot better with that since moving to Ponyville,” she explained to him.
He shook his head a bit, adjusting to the sudden change of scenery, “It shows!”
The park was lit with the natural lighting of the moon and stars as lightning bugs flew around the dark field. The occasional tree and bench filled in the serene area, although there were no ponies in sight. His gaze did turn to the large tree nearby, “Hey, isn’t that-”
“Our playhouse,” Twilight smiled, trotting over to it. The two had spent countless hours here, using their imaginations to turn it into whatever it is that they needed. A ship to cruise the seas, a rocket to see the stars, or far more often, a house for their budding family.
Shining smirked a bit, “You know, when you look at this, it isn’t too surprising you went on to live in a tree.”
Twilight smiled a bit, “A library and a tree, the perfect place for me,” she brought a hoof to the tree at the same time that her brother did. The two slowly turned and exchanged looks, knowing exactly what to do.
* * *
“Honey, I’m home!” Shining declared, collapsing into a bed underneath the tree they called a home. The blankets smelled vaguely of lavender, he had to wonder how exactly Twilight had gotten it.
She had spent the last few minutes teleporting in or creating a bunch of homely thing for their games. While he had initially assumed she was creating these with her advanced lessons from Princess Celestia, it was just as possible that there was a pony somewhere in Canterlot missing their bed, lamp, table, and refrigerator.
Twilight herself knew though, and she made a note to return all of this after they had their fun. With what felt like half of Canterlot at Spike’s party, she was sure the bed wouldn’t be missed for a few hours more.
“Oh, how was work?” She asked with a giggle, walking over to him.
“Busy, I spend all day keeping the rowdy guards in line and had to spend my break checking over the new armor. Time I would have rather spent thinking of you, my Sweet,” Shining said, only a little bit awkwardly as he tried to get back into the spirit of the game.
Twilight smiled, “What a charmer you are. I spent the day working at the library, it was pretty quiet. Although I’m happy to finally be home with you,” she waved a hoof around the field, about as far away from a proper house as could be imagined before she rolled into the bed as well.
She looked into his eyes, realizing just how much she missed him. During the last couple of years, they hadn’t been able to see each other at all. They were living in separate places, both deep in their own duties and responsibilities. Even letters had slowed down as the two simply had too much to do.
Maybe it was the drinks that she had taken before coming out here. Maybe it was the relief of saving Equestria from the changelings and seeing her mentor and family safe. Or it was just the joy that she could finally see her brother.
All she could think as she leaned in and kissed Shining was that Sugarheart hadn’t mentioned this in the book.
Her brother’s sapphire blue eyes widened as she kissed him on the lips, but he didn’t pull away. His lips were warm and soft and she found herself regretting the moment that she moved away.
“I-I’m sorry,” her face felt hot, “I, uh, don’t know what came over me…”
Shining’s blush was obvious through his white fur, “W-We were really getting into character, that’s all…”
“A book I read did mention physical exercise can help when you’re feeling stressed…” Twilight pointed out, neglecting to add this was certainly not what the author had in mind, “Also, this is technically your bachelor party.”
Shining Armor couldn’t argue that, rubbing his chin, “Cadence is the embodiment of love… In all of its forms…”
Her yearning feelings took over as Twilight kissed him again, realizing they were only taking the game to its natural conclusion. It only made sense that everything had been leading up to tonight. She brought her hooves forward and wrapped them around her brother, embracing his muscular body.
He began to lean down and kiss her chest, rubbing against her and embracing his sister with his larger body. Before going to Ponyville, Twilight would have been scared, anxious, ready to let her brother take the lead and simply enjoy the ride.
Except now she had stopped monsters and threats across Equestria, from Nightmare Moon to Discord. She had faced the worst that the world had to offer and had emerged victorious.
She grinned, and began to rub against him, spinning until she was on top, “Show me what you got, you handsome stallion.”
“A-Are you sure…?” He asks.
She grinned, “Of course I’m sure! Show me, Shining Armor!”
She felt something rub against her, feeling the cock against her belly before she felt it enter her, making her gasp aloud. She tensed up, taking a deep breath as she felt her brother inside her. She shut her eyes as he began to grind inside her, moving in and out.
“K-Keep going,” she ordered, leaning down to give him a better angle. She wasn’t sure what she should have expected, but this wasn’t it. The thrusts pushed her entire body forward and back, so all-encompassing that she couldn’t focus on anything else, letting out a moan.
Shining Armor was just getting started, leaning up and biting her neck lightly, moaning. Twilight couldn’t focus on him though, trying just to keep from climaxing early as Shining pushed in increasingly faster.
She had read many books on the subject, but experiencing it was something else entirely. The handsome, manly stallion was making her feel like the only mare in the world that mattered, all his focus was on her. He nipped at her, he licked, he kissed her neck and he just kept going.
Twilight screamed as she felt herself climax, followed shortly by Shining as she felt herself getting filled with his seed. She took a few ragged breaths, trying to recover from her first sexual experience with a stallion.
Shining was red as he breathed in hard, laying back on the bed, “You okay, Twily?”
“Y-Yes… I didn’t imagine it would be so… intense,” she admitted between heaving, “I-I wasn’t bad, was I?”
“What? Of course not,” he winked, “W-Why stop here, huh? We got all night.”
Shining grinned a bit, “Oh, yes… All night.”
The hours flew by for Twilight, she was surprised by just how much endurance she really had to keep up with her brother, a trained and experienced captain of the royal guard. She had thought that he might be a bit worn out after the changelings and the wedding, but through his panting and sweating he refused to slow down. It only inspired her to keep up with him, even occasionally sneaking in magic to grant more stamina or make their bodies even more sensitive.
She was quite proud of herself when it was her brother that finally conceded after quite a few orgasms, “T-Twily… I’m spent.”
The young unicorn grinned, “I would think so, I counted… Thirty-one orgasms! You make a particular whinny each time you ejacu-”
“Thirty-one?” He interrupted, jaw dropping, “I… Wow. I think I just amazed myself.”
“You certainly amazed me,” Twilight admitted with a giggle, moving her sweaty mane out of her eyes, “You’re a real stallion, Shining Armor. I wish I could have taken notes. Or read about sex in advance, we could have made it even better!”
“I-I think we had a really good time as it is,” he chuckled weakly.
She nodded, laying back in the bed with her brother as the two panted. She looked up, noticing that it was a clear sky, the stars were out in full force tonight. Laying here in the ecstasy of a successful night, she didn’t want it to ever end.
It couldn’t last forever though as a tired Shining fell back against the bed, looking up, “Cadence is going to kill me.”
Twilight turned to him, “What makes you say that?”
His eyes widened, “Did you… miss what we just did?”
“I wouldn’t worry about that,” Twilight explained, “Princess Cadence is the embodiment of love itself, like Princess Celestia represents the sun and the day and Princess Luna is the night. Your wife appreciates love in all of its forms,” she put on a cheeky grin, “She was my foalsitter long enough for me to know that.”
Shining still didn’t look convinced, “This is a little different…”
“Not to mention this is your bachelor party, the last time you’re expected to go wild and enjoy yourself… Even if Spike had it done out of order. Considering everything that’s happened recently, I think we all know that you and Cadence are meant to be together. She knows it too.”
The white unicorn sighed, “I… suppose you might be right…”
“Besides,” she winked, “We were just playing house.”
The pair enjoyed each other’s company for a bit longer before she finally forced herself back up, “Let’s… clean this bed and send everything back,” she suggested, wincing a bit at how sore her hindquarters were. Moving was much harder now then it was in the heat of the excitement.
Shining Armor agreed, pulling himself out of the bed next. Twilight took a quiet satisfaction to see that he was clearly worn out as well. He turned to her after wiping his mane, “So what’s the plan, little sis?”
She grabbed the sheets with her magic and moved over to him before teleporting the pair to her room in the castle. After a hazy few moments where she shook her head and gathered her bearings, she explained, “We clean the sheets, we shower, I send everything back, and we head back to the party.”
While cleaning the sheets was mundane, the shower was far more interesting. The two ponies were a bit too worn out for full-on sex in the shower, they were able to stand up inside it and have some fun before their nights came to an end. She never would have thought that her brother was so good with his tongue. She resolved to read a book for tips later.
By the time the two had returned to the party after erasing all hints of their outdoor diversion, the party was just slowing down. Many of the guests had gone home, making things a far more intimate affair. She noticed that Applejack was helping a woozy Rainbow Dash out of the room, leaving just a few other ponies left, along with Spike.
The young dragon approached with a smile, “Hey, Twi. Pretty cool party, huh?” He asked, looking quite pleased with himself.
She smiled at him, “The best.”
* * *
She and her friends returned to Ponyville a few days later, after they were given enough time to see the sights and catch up with old friends. She had caught her brother and Cadence a few times after the bachelor party and was satisfied to see that her theory was correct. If anything, Princess Cadence seemed to be in even greater spirits.
With this in mind, it didn’t surprise her when she received a letter a few days later from her sister-in-law. Taking it alone in her room, she read,
Dear Sister-In-Law,
Next time, I insist on a threesome. If you’re going to play house, you need to have your new sister join! I’ll be sure to give you some tips about Shining when we next meet up, I have some ideas I’d like to try with you.
I hope we can meet up soon. We don’t want to keep the stallion of the house waiting, do we? At least not too long.
Lovingly yours, Cadence.
The letter smelled of scented primrose and was marked with the royal insignia. Twilight smiled to herself, placing the letter away and grabbing her copy of The A-B-Cs of S-E-X, Volume VII.
