Of Fillies and the Colts Who Fuck Them

Dear Shining,

I want you to fuck me.

I honestly don't know how else to say it. I'm so horny it hurts. I want to ride your cock. I want you to plow me, to ram me, to fill me with your cum and get me pregnant. I want you to get your little sister pregnant, to shove your cock down her throat, dominate her oh fuck oh goddess goddess yes

...Sorry. I was, um, multitasking a bit at the end there, and I think I lost control of my speech-to-text spell for a moment. Just disregard those cries of divine inspiration.

I am in my right mind, though, when I say that I miss you. I have no roommate here at school, so things tend to get a bit lonely at night. I try to imagine you holding me as I fall asleep, but nothing can compare to the peace I feel whenever I feel your breath on my neck, your body pressed against mine.

It's hard to believe that I've been away for four months already. It feels more like three lifetimes. I know that you must feel the same way.

In any case, I'll be home in just a few days for Hearth's Warming! I can't wait to see you. I've been studying up on my Ogres & Oubliettes lore, just for you. I know how badly you've wanted to play with me since you taught me the rules over the summer (I'm sorry again for breaking that plastic dragon figure of yours—I swear, I didn't see it before I sat down).

I can't go a moment without thinking about you. I love you so, so much.

Always yours,
Twilight

P.S.: I attached another picture. It took me about ten minutes to get the shot just right. Hope you like it.

Shining Armor chuckled and put the letter down on his desk. He took a breath before flipping it over to look at the photo clipped to the back—only for all the air to leave his lungs.

He stared straight into Twilight's teenaged pussy, spread wide for the camera. Shining muttered a curse and held it close to his face. The picture still smelled of musty old books, and within seconds a pang of desire echoed through his bones. A familiar tingling ran down his spine and between his legs.

He held the photo aloft with magic and laid his forehooves on either side of his stiffening shaft. Taking deep breaths, he allowed himself a soft stroke, then another, and then another—over and over until he was pumping hard, jacking off to a picture of his little sister.

The thought didn't even phase him at this point. Under his bed, he kept a small box filled with dozens of letters and pictures just like this, each one lewder than the last.

Still hard at work, Shining picked up the letter and read it over again. It had been six months since that night in the bathtub, and four months since Twilight had returned to Princess Celestia's school. Only four days remained until Hearth's Warming, but there was only one thing Shining really wanted: a day alone in bed with his sister.

But, of course, things were a bit more complicated now.

"Shiny!" Cadance called from somewhere outside the room, "where are you?"

Shining let out a yelp and pushed his chair away from the desk. He tore open a drawer and thrust the letter and picture inside, before slamming it shut and spinning around in his chair to face the door.

"In here!" Shining yelled back, taking deep breaths to calm his racing heart.

The bedroom door opened, and in strode Cadance. The young princess kept her back straight and her head high, moving with an air of grace and elegance usually reserved for goddesses. They locked eyes, and Shining felt his jaw go loose, felt every hair stand on edge. Just glancing into her bright blue eyes was like being hit by lightning.

"There you are," Cadance said, sauntering up to the desk. She leaned forward and the two of them exchanged a short kiss. She pulled back and smiled. "I stopped by the Tabletop Gaming Club to find you, but they said that you skipped today! You never skip a game of Ogres & Oubliettes. What's going on?"

The answer flew to Shining's mind: it was Friday, and Twilight's letters always came on Friday.

"It's nothing," Shining said, looking away. "Just wanted to get a headstart on my holiday homework, y'know?"

Cadance smirked. "Oh, really? Is that why there's no books or papers on your desk?"

Shining froze. "Uh..."

With the lightest of giggles, Cadance reached forward. "Or why your dick is so hard?" she asked, running a hoof down his shaft.

Shining winced at the sudden pleasure and cursed himself for not thinking to cover up. "That's just because of you!" he said, forcing a laugh.

"I bet." Cadance licked her lips and knelt down until she was eye-level with his rod. "Shining Armor, skipping out on his friends to go play with himself. How did I ever get such a naughty little coltfriend?"

"I dunno," Shining said, leaning back in his seat. He smiled. "How did I get such a sexy marefriend?"

"It's a mystery." Cadance lit her horn, and the bedroom door slammed shut, locking with a click. "But it's okay. If you want to be naughty, Shiny, that's fine. I can be naughty too, after all."

Shining closed his eyes as Cadance wrapped her lips around the tip of his cock. She circled the head with her tongue, lapping up the precum already there. She took a moment to pull out and just rub his cock against her cheek, smearing his nectar and her saliva against the soft hair on her face. He let out a moan at the sharp pleasure spiking through his veins, which only grew when she went back to sucking.

She took him in until her cheek bulged with the girth of his dick. She lit her horn and wrapped his balls in blue magic, running ripples of energy across the tender skin.

He grunted and grabbed her head, pulling her deeper. Cadance made no fuss as his twitching penis slid along her tongue and down her throat. Her throat was tight on Shining's meat, and grew even tighter with every bob of her head. She moved her head up and down, up and down, taking him deeper every time.

Shining's breaths became staccato gasps. He gripped her hair and pushed his dick in as far as it would go, until Cadance could barely make a sound. Light purple sparks flew from his horn. Every limb trembled.

The pressure in his loins grew and grew until his thoughts fell apart. All he felt was Cadance's lips and tongue and throat against his cock.

Cadance reached back and swiped a hoof along her dripping cunt. She rubbed her wet hoof on Shining's balls.

That was enough to earn a ear-splitting bray from Shining as his cock flared in her throat. A thick rope of jizz spurted from the tip of his dick, painting Cadance's throat white.

Before he could let out another blast, Cadance pulled out his cock and opened her mouth. Long strands of cum splattered over Cadance's face. It coated her hair and dripped down her chin. Even as Shining calmed down, Cadance grabbed his cock and licked the head clean. She traced her hooves down his fading veins.

"Cadance," Shining said through labored breaths. "You... You're..."

"The Queen of Blowjobs? I know." Cadance left his dick with one last kiss before standing up. She smiled and laid a hoof on his. "I love you, you know. Really. More than anything."

Her words hit Shining like a baseball bat. Flashes of purple danced through his mind—but he still returned her smile and said, "I love you, too. More than anything."

Cadance's cheeks seemed to go even pinker than they already were. She stood up and walked to the door. "C'mon," she said. "I think I saw your mom making sugar cookies when I walked in."

Shining moved to stand up, but stopped short and thrust out a hoof. "Wait!" he shouted. "Your face, it's still...!"

Cadance wiped a hoof along her sticky cheek. "Oopsie," she said, licking her hoof clean. She trotted over to Shining's bathroom. "Be back in a sec, sweetie."

As soon as Cadance closed the door to the bathroom, Shining spun around in his chair and took out Twilight's letter. He gave it one last read—then, with a sigh, walked to his bed and tucked it away in the box with all the others.

"I'm home!" Twilight sang, hauling her suitcases through the front door. When one got stuck on the doorframe she grunted and closed her eyes, focusing her magic. Almost immediately the suitcase sprang free, careening into the house and bowling her over. Twilight spun across the foyer, limbs splayed out in every direction, before coming to rest right at the bottom of the staircase.

She groaned and rubbed her aching head, only to open her eyes and find her father standing above her, a wide smile draped across his face.

"Dad!" Twilight said, springing to her hooves. She jumped up and wrapped her forelegs around his neck, trapping him in a tight hug.

"Hey there, my little princess!" Night Light said with a chuckle. He nuzzled his daughter, digging his muzzle into her neck. "Oh, I've missed you so much."

"Same here," Twilight said. She let go, dropping to the floor, and scampered off into the living room, leaving her father to deal with the suitcases.

Before Twilight could even take a step into the living room, she found herself lifted into the air by a familiar pink aura. Twilight Velvet had been lying in wait, and when Twilight entered, she picked her up off the ground and twirled her around the room before pulling her into a hug.

"Happy Hearth's Warming, sweetie," Velvet said.

Twilight giggled and tried to free herself from the motherly trap. "It's still a few days until Hearth's Warming, Mom. We've got time!”

“Well, yes, I suppose—but look!” Velvet gestured behind her to the lopsided tree that stood in the corner of the room. Its branches stuck out at crooked angles, and the star at the top scraped against the ceiling. “We’ve already got all the decorations up. Hearth’s Warming season is in full spring! I even had your father chop down the tree himself!”

“Uh-huh.” Twilight tilted her head to make up for the tree’s bend. “I can see that.”

“All the magazines have been saying that using magic to cut down trees makes them die quicker,” Velvet said, walking over to admire the ornaments. “So no magic this year. I think it makes the needles look quite vibrant, don’t you?”

A million books and research articles disproving Velvet’s theory ran through Twilight’s mind. Yet, she just sighed and put on a smile. “Sure, Mom. Whatever you say.”

As Velvet hummed and set to work picking up a few ornaments that had slipped off their branches, Twilight gazed around the room. Nostalgia bloomed with every glance. By the window stood her father’s antique nutcrackers! And next to the radio, her mother’s dolls of the three tribe leaders! Princess Platinum had always been her favorite to play with as a filly.

Twilight’s gaze floated across the room, until she reached the fireplace and, more importantly, the stockings that hung above it. At the top of a long woolen stocking emblazoned with a shield, a familiar name jumped out at her...

Turning around, she asked, “Mom! Where’s Shiny?”

“Shining? He should be in the kitchen, along with—” Velvet was cut off by a porcelain candy cane tumbling to the floor and cracking in half. As her mother mumbled a curse, Twilight hopped out of the room and off to the kitchen.

The trip down the hall to the kitchen felt like a marathon to Twilight, it seemed so long. She watched the checkered linoleum floor grow closer and closer, feeling more like she was in a movie than real life.

Yet, when she scrambled into the kitchen and locked eyes with her brother, the joy that welled up in Twilight’s chest felt as real as anything.

“Shiny!” Twilight yipped, running in so fast that when she tried to stop she slipped and slid across the floor.

Shining hopped to his hooves and shoved the book he had been reading away. “Twily!”

The two sprinted to meet each other in the middle of the room. Shining picked Twilight up and reared back onto his hindlegs, spinning her around in a wide arc. Their voices filled the air, each laugh filled to the brim with happiness and excitement and relief.

When Shining finally let his sister go, barely a second passed before Twilight was on him again, planting a solid kiss on his lips. He flinched, but didn’t pull away until a few seconds had passed and Twilight had managed to slip her tongue into his mouth.

“Twi,” he stammered, glancing at the doorway. “Not that I don’t wanna spend the rest of the day making out, but maybe not here...?”

“Oh, stop worrying,” Twilight cooed, rubbing her face against his chest. “It’s not like we haven’t done this before. Remember the day before I left for school? What we did on the kitchen table, while Mom and Dad were listening to the radio?”

Cheeks burning, Shining moved his lips wordlessly a few times.

“What, cat got your tongue?” Twilight asked, sticking out her tongue. She bent down a bit and glanced between his hind legs. “Don’t worry. You remember.”

As Shining stayed stiff in the middle of the room, Twilight rolled her eyes and trotted over to where Shining had been sitting. A catalog sat open on the table, and when Twilight looked at it, her eyes grew to the size of planets.

“Oh, my—Shiny, is this for me?” Twilight asked, picking the magazine up and stuffing it in her brother’s face. The catalog was open to an advertisement for a local jewelry store; Clear Cut’s Crystal Creations was offering a sale on enchanted rings and spellbound necklaces.

At the bottom of the page was a picture of a pair of pendants. As the text next to the picture noted, when one was activated with magic, the other would glow. “Perfect for that special somepony,” it read. “Let them know you’re thinking about them, no matter where you are.” The picture had been circled in red marker, and Shining’s messy scrawl next to it read, “Check this out for her.”

“Well?” Twilight asked. “Is it?”

Shining blinked. “Uh.”

“It is, isn’t it?!” Twilight squealed. She tossed the magazine back onto the table and jumped high into the air, laughing like a filly possessed. “Oh, Shiny, how did you know I love enchanted jewelry? I’ve always wanted a pendant like that!”

“Um.”

“The magic contained inside—it has to be at least a Level Three Tracking spell. Do you know how hard those are to pull off, let alone capture inside crystal? Imagine how jealous everypony back at school will be when I walk into class wearing one!”

“Ah.”

Twilight giggled again and leaped forward, wrapping her forelegs around Shining’s neck. “Thank you, Shiny. I love it.” She craned her neck to kiss him again.

However, before she could land the kiss, Shining turned his head, forcing Twilight’s lips to land on his cheek. When Twilight felt the fur in her mouth, she screwed up her mouth and pulled back.

“Huh?” Twilight raised a brow as Shining pushed her away. “What are you—”

“Twily?” came a light voice from behind her. “Is that my favorite filly?”

Twilight spun around, her frown bouncing into a grin. “Cadance!”

Both mares immediately jumped into a tried-and-true routine: “Sunshine, sunshine, ladybugs awake! Clap your hooves and do a little shake!”

By the time they finished, Shining had managed to wrest back enough control of his body to nod and say, “Twilight’s back for Winter Vacation!”

“Is that so?” Cadance asked, sharing a nuzzle with Twilight. She strode over to where Shining stood and touched his chin with her hoof. “Oh, this is lovely! Hearth’s Warming is the best time of year, isn’t it?”

Shining gulped, but smiled. “Yeah, it’s great! Uh, Cadance, maybe we should go—”

“What are you doing here, Cadance?” Twilight asked, taking a seat at the table. “Don’t tell me Mom thinks I still need a foalsitter.”

“Oh, it’s nothing like that,” Cadance said. “I’m just spending some quality time with Shiny. We don’t take any of the same classes in school, and it’s so hard to make time to see each other”—she pulled him close, until her breath tickled the hair on his neck—“unless, of course, we sneak away. No one ever looks in the band room closet...”

“You’re hanging out in a closet?” Twilight asked. “That can’t be very comfortable.”

“We make do,” Cadance said. She rubbed her horn against Shining’s and sighed. “Spending the holiday season with my favorite colt in the world—how could things get any better?”

Twilight cast a seductive glance at Shining. “I think I might have one idea.”

Cadance gave him the same look. “Same here.”

Shining’s eyes flicked between the two fillies. “Cadance, I don’t think—”

Cadance kissed Shining.

It took Twilight a moment to comprehend. She stared at the two with wide, unflinching eyes, taking in every slow twitch, every small move as Cadance grabbed Shining and pulled him deeper. Twilight just watched as a mare that she trusted snogged a colt she loved.

Shining, still caught in the kiss, met Twilight’s gaze.

Then Twilight crumpled.

Her ears went flat. Every thought she had crumpled into dust, replaced by a boiling stew of confusion, horror, disgust—anger. Her hooves burned. She wanted to leap forward, to tear them apart, to beat Cadance to a pulp. What was she doing? Who gave her the right?

And why isn’t Shining doing anything?

“...Twily?”

Twilight snapped back into reality, only to find Cadance staring at her with a raised brow. Shining had backed off, ears flat, studying a crack in the linoleum.

“Are you alright?” Cadance asked, reaching forward to touch her shoulder. “You look like you’re about to be sick.”

“Don’t—!” Twilight jumped away. She bit her tongue, then managed to put on a smile. “I’m fine. Just... just a little tired from the carriage ride home.”

“You must be starving,” Cadance said. She grabbed Shining’s hoof and pulled him forward. “C’mon, Shiny. Let’s see what your mom has planned for dinner.”

Shining stumbled after her. He left Twilight with one last apologetic glance before escaping around the corner.

Silence wrapped around the kitchen. Twilight gripped the chair she sat on.

Sitting all alone in a cold room—it was like she had never left school.

As the clock struck midnight, the Sparkle household was quiet—except for the constant metallic squeaking coming from Shining’s bedroom.

The bed shook under them. Shining held Twilight’s sides hard, thrusting into her harder and harder. His cock slipped in and out easily, letting nectar spill down Twilight’s legs and onto the bed. As he pounded her, relishing the feeling of his shaft against her warm walls, he leaned down and buried his muzzle into her neck.

Twilight bit down on a hoof to keep quiet, but when she felt Shining’s teeth nipping at her skin, she couldn’t help but gasp. Shining had her pinned to the bed. She tried to take a breath, but Shining kissed her, stealing the chance. Twilight didn’t resist. She pushed back, slipping her tongue into his mouth.

“Oh, fuck,” she said, wrapping her forelegs around his back to keep him close. He rammed hard enough to push her back into the pillows. “Fuck, fuck, fucking fuck—”

“Is that the only word you know?” Shining asked, breathing into her shoulder.

Twilight smiled. “Ugh, be qui—aah!”

Her body bucked back, and Shining felt her pussy clamp down on his dick. At once he snorted and slid his entire length inside. He came, and thick, milky cum spilled out of him, flowing into his little sister’s womb. He craned his neck high and held his ground, spurting inside of her as long as he could manage. Then, legs trembling, he pulled out and collapsed next to her.

Their juices soaked the sheets. For a moment, the two just breathed, trying to regain control of their senses.

A purple light filled the room, and Shining opened his eyes to find Twilight with her horn alight. The magic swept over her young body, concentrating between her legs.

It was a spell Shining had seen dozens of times before: an anti-pregnancy charm. Without it, he and Twilight would have been expectant parents months ago.

Her hornglow faded, and she rolled over to press her body against his. He sighed and held her close. That familiar ‘old book’ scent filled his nose and lulled him to sleep—

“I love you,” Twilight said, pressing her face into his chest. “More than anything.”

Shining frowned. “Yeah,” he said, the warmth in his chest turning to sludge. “Same here.”

“Did you keep my letters?” Twilight asked. “I know I sent a lot of them, but honestly there isn’t much else to do outside of class, and I get horny a lot, so...”

“Yeah, I kept them,” Shining said, brushing her hair. “And the pictures.”

Twilight tittered. “Hey, do you wanna go out tomorrow? There’s this nice café that I heard opened downtown.”

“Can’t. I promised Cadance I’d help wrap presents.”

He felt Twilight go still next to him. “How long have you two been... together?” she asked.

Shining shrugged. “Two months?”

“You never mentioned that in any of your letters.”

“It—it never came up.”

Twilight wriggled out of his grasp and turned away.

“What’s wrong?” Shining asked.

“Nothing.”

“Are you jealous?”

“No,” Twilight spat through gritted teeth.

“Then what’s wrong?”

“I said ‘nothing.’” Twilight pulled the blankets over her face. “Go to sleep.”

Shining fell asleep staring at the back of his sister’s head, silently begging her to turn around and smile. It never happened.

Night Light sighed as he hauled hundreds and hundreds of colored lights out of a cardboard box. “Mind explaining to me again why I had to throw out all our old Hearth’s Warming lights and buy new ones?”

“By your own admission, the old ones were just that: old,” Twilight said, turning up her nose and putting on her best lecture voice. “I’ve run the calculations, and these new lights will last a minimum of three days longer than the last, while providing a higher lumen cap. Those three days and that lumen cap are more than worth the amount of utils expended by buying them—”

“Alright, alright!” Night Light said, grinning as he massaged his temples. “You’re making my head hurt.”

Twilight giggled. “That’s what you get for buying me all those economics books last year.”

“I guess so. Maybe I should think about throwing away some of the ones we’ve got waiting under the tree...”

“Throwing away books?” Twilight asked, smile disappearing. “Don’t even joke.”

Night Light chuckled and tossed a rope of lights to Twilight. “Speaking of the tree, your mom wants me to try and saw off the bottom. I think she’s finally noticed that it’s not exactly, y’know... stable.”

“Go,” Twilight said, waving him off. “Before she has a conniption. I can handle the lights.”

Night Light nodded his thanks and walked off, plodding across the snow-covered yard to the shed next to their house.

Twilight turned her attention to the forest of wires that sat before her. She had assured her father she knew how to string these up, but did she? Which end had the plug? How was she supposed to make them stick to the outside of the house? Was there some sort of spell? She stuck out her tongue and lifted up one end—only to realize that they were all hopelessly tangled.

She snorted. “Figures. According to Job’s Third Law, if two wires rest within three inches of each other, they will get tangled.”

“Really?”

Twilight’s ears perked. She turned around, only to scowl.

Standing under a tree, Shining waved. “That’s interesting!”

After a moment’s pause, Twilight rolled her eyes and turned away.

“Can I help?” Shining asked, hurrying through the snow to where she stood. He grabbed a wire out of her magic. “I did this last year and—”

Twilight snatched the wires back. “I’m fine.” She walked away from him and began untangling the lights. “Why don’t you go hang out with Cadance?”

Her horn burned. She ripped the knotted wires apart, not seeming to do anything but tangle them more. Her thoughts told her to slow down, to pay attention to what she was doing, but she could barely see straight. She felt Shining’s gaze on her back, and felt a stinging in her eyes—

“I’m sorry,” Shining said, appearing at her side.

Twilight sniffed. “What for?”

“I should have told you about Cadance,” Shining said. “I swear, I didn’t want to hide it from you. It just happened so fast; one day we were just friends, and the next day we’re going on dates and all that stuff. I guess I was nervous about what you would think.” He shuffled his hooves. “Are... are we okay?”

Twilight bit her lip. She wanted to yell, to scream at Shining for what he had done. What did Cadance have that she didn’t? Why hadn’t Shining broken up with her yet? What was wrong with him?

But the furious words never arrived. How could she yell at Shining? Her love for him was greater than any anger.

So she just nodded, spun around, and hugged him. “Yeah,” she said. “We’re okay. Sorry for giving you the silent treatment.”

“Eh, it’s okay.” Shining kissed her on the cheek. “I probably deserved it.”

Twilight kissed him on the lips. “Yeah. Probably.”

As Shining went red, Twilight tossed a ring of lights at him, letting it land across his shoulders. The two set to work stringing the lights up along the side of the house.

“So,” Twilight said, wrapping a wire around the gaslamp above their front door, “are you excited for the Hearth’s Warming Party? Mom’s been ranting about it since I got home.”

“Yeah, I’m excited. Cadance is coming, and she’s gonna—” Shining stopped when he saw Twilight’s glower. He flinched. “Oh. Sorry.”

“It’s fine,” Twilight muttered. Closing her eyes, she let out a heavy sigh. “Just, y’know, make some time for me, okay? I’m... it’s lonely without you.”

Shining touched his tail to hers. “I’m not leaving you, Twi. Not ever.”

Smirking, Twilight lit her horn and grabbed Shining’s dick. “You better not.”

Shining jumped and let his own horn wink out. A jumbled mess of lights fell from the air, right onto his head.

Twilight and Shining dodged from room to room, ducking under gazes and weaving around couples. They chittered and chattered as they went—“Who the hay is that? Do we know them?” “I think that’s one of Dad’s friends.” “Dad’s friends with a camel?”—but kept their speed, making sure to stay out of sight.

“I thought Mrs. Petunia would never stop talking,” Shining whispered as they finally stumbled into an empty hallway and escaped the party crowd. “I don’t think I could have listened to another word about her cats without losing my mind.”

“You’re lucky,” Twilight said. She sat down against a wall. “Mom used to send me out to buy flowers from her. She lives right down the block, but each trip took an hour!” The two laughed. The bustle of the party roared around them, filling the hallway.

Shining glanced around the hall, wondering why the party hadn’t spread there yet—but stopped when he met Twilight’s heady gaze.

“You know,” she said, “we could fuck right here, right now. I bet nopony would find us.”

“No, no, that’s...” Shining gulped. “You really think so?”

“Yeah. Cadance hasn’t arrived yet. Nopony’s gonna come in here.” Twilight stood up and touched his chest with a hoof. “At least, not yet.” She licked her lips and ran her hoof along his side. As Shining shuddered, she kneeled down and moved her mouth to meet his shaft.

His dick was still soft when it met her tongue, and Twilight took the entire thing into her mouth. She held it there, smiling as it hardened and grew, poking against her cheek. Shining moaned, and Twilight moved down, running her tongue along the length of his shaft and across his sack.

“There you two are!” Velvet said, popping into the hall.

“Mom!” the siblings said in unison, both jolting up straight. A small spot of saliva dripping from her mouth, Twilight shook her head and yelped, “This isn’t what it looks like!”

“It isn’t?” Velvet asked, narrowing her eyes. “You two aren’t just hiding away and hoping I won’t notice you left the party?”

The two exchanged a glance. “Uh.”

“Well, if that’s the case, you were wrong!” Velvet said, putting on a triumphant smile. She flipped her hair and grabbed them both by their hooves. “Now, come! Your father just took out the camera, and I want a good family picture to send to Grandma Sparkle.”

The two didn’t resist as their mother pushed them out of the hall, back into the party. A small ring of saliva still clung to Shining’s rod.

“Twilight, stand up straighter. Shining, stop rolling your eyes! If I see one more—agh, Celestia dammit!” Night Light swore as the tripod collapsed and sent the camera tumbling to the floor.

Twilight gasped, and around Night Light a few party-goers chuckled. Velvet cleared her throat, but kept on a smile. “Dear,” she said through her teeth, “please, watch the language.”

“Yeah,” Twilight said. “You can’t say that about Princess Celestia. She’s... she’s Princess Celestia!”

“Really?” Shining asked, elbowing his sister. “I never would have guessed—ow!” Shining jumped away and massaged his hind leg. Twilight smirked.

“Okay, I think I’ve got it.” Night Light fiddled with the knobs and buttons on the large camera. The tripod collapsed again, but before the camera could hit the ground, Night Light caught it. Muttering curses, he just held it to his face. “Smile!” The three Sparkles followed the order, and the camera flash doused them in light.

Twilight tried to keep focused on the camera, but the flash eventually grew so bright that she had to look away. She shifted her gaze instead to her brother’s face. As the camera went off, he flashed that bright, beautiful smile of his. That smile lived in Twilight’s dreams, could turn her into a puddle with just one look.

She felt a breath catch in her throat—and along with it came an idea. No, less than an idea. An instinct.

Between pictures, Twilight turned back to her father. Out of the camera’s sight, she lifted a hoof and laid it on Shining’s balls.

His meaty sack was warm against her hoof. She moved her hoof around, savoring the way the soft flesh moved. They stood against a wall, behind their mother, so she knew no one would see. Even so, what she wouldn’t give to kneel down right now and go back to licking his balls, to suck them until he went hard. She could keep massaging them as she swallowed his cock, as she drank every drop of his jizz.

“Twilight, Shining!” Night Light snapped. “Stop making ugly faces!”

It took Twilight a moment to realize her face had melted into a slack-jawed grin, making her look more like a panting dog than a pony. Next to her, Shining had a long frown across his flushed face.

“Oh, they’re just having fun,” Velvet said. “Making weird faces in pictures is all the rage these days. I read an article about it!”

Night Light rolled his eyes, but said, “Fine.” He put the camera down and slapped a hoof against it a few times. “Now I just have to figure out how to get the pictures out of this thing...”

“We have to develop the film,” Velvet said.

Night Light stared.

“Oh, just let me have it." Velvet jumped up and rushed over to her husband. As Velvet showed Nightlight how to take out the film—he refused to listen, claiming that all this new technology was sending everypony to Tartarus—she glanced at her children and said, “Stay out of trouble, you two. And go talk to Mrs. Petunia. She looks lonely.”

“Sure, Mom,” Twilight said. She turned and tried to walk off—but before she could take a step, Shining stamped a hoof down on her tail, forcing her to fall onto her rear.

“What the hay do you think you’re doing?” he hissed into her ear. His voice shook.

“I know what I’d like to be doing,” Twilight said with a wink. The pink in Shining’s cheeks turned to crimson. Chuckling, Twilight flicked her tail against his nose and sauntered away.

She waited until she was halfway across the room to glance over her shoulder and make sure that Shining was following. Sure enough, there he was, stomping after her with an incredibly sexy scowl stretched across his face. Twilight threw him another wink, and that just made him go redder.

They passed through a doorway into an empty room. She scanned the space, looking for—There!

“Twilight,” she heard Shining say. She quickened her pace, headed for another doorway. When she reached it she stopped, sat down, and waited for her brother to arrive. He leaned into her, pushing his face close to hers. “We need to talk.”

“I’d love to talk,” Twilight said. She flicked her eyes upwards. “But first...”

Shining followed her gaze, up to the sprig of mistletoe that hung above them. “What are you... oh. Oh—”

Twilight leapt forward and kissed her brother. He went stock-still at her touch, but that didn’t stop Twilight from grabbing his neck, nibbling at his soft lips. His musky scent surrounded her, and heat bloomed through her chest. She leaned into the kiss, standing on her hind hooves.

With a growl, Shining pushed her away, and she fell back onto her rear. “Stop!” he said in a strangled yelp. He tossed his head from side to side, looking for anypony who had witnessed their tryst. “We’re in public! Do you know what would happen if anypony saw us?”

“Well, yeah, but—whatever!” Twilight touched his hoof. “It was just a kiss. It’s nothing!”

“Your ‘nothing’ is gonna get us in big trouble,” Shining said, snatching his hoof away.

“You were fine with it back in the hallway.”

“That was different! Nopony was around!” Shining shook his head. “We can’t do stuff like this where everypony can see. I mean, what would Mom and Dad say? What would Celestia say?”

Twilight was taken aback for a moment, but soon sneered. “Are you really worried about them? Or are you worried about Cadance?”

“Did someone say my name?”

Both siblings jumped at the sound of Cadance’s voice. The young princess trotted towards them, a jeweled saddle resting upon her back. She grinned at them both, and offered Shining a quick peck on the cheek.

“Sorry I’m late,” she said. “How are my two favorite unicorns doing?”

Twilight glared. With a huff, she flipped her hair and walked away.

“What’s with her?” she heard Cadance ask as she left.

Shining sighed. “It’s a long story.”

As soon as she knew she was out of sight, Twilight broke into a sprint, running until she reached the living room. She trudged through the crowd, hooves dragging along the carpet, before collapsing into the couch.

The party bustled around her, but laying there on the couch, Twilight felt a million miles away. No one looked at her—no one seemed to even realize she was there. Every emotion in her raged; anger and sadness crashed together, melding into some strange sea of nausea.

She held a pillow close to her chest and clenched her teeth, trying to ignore the stinging in her eyes.

Shining eyed the glass bottle in front of him warily. “Cadance, sweetie—are you sure about this?”

“Shiny.” Cadance leveled him with a steady stare. “Do I look unsure to you?”

“Well, no, but...” Shining took a deep breath, then glanced around the kitchen to make sure they were alone. “I’m pretty sure this is illegal.”

“Illegal? I’m a Princess, Shiny. Everything I do is legal.”

“Giving alcohol to minors is legal?”

Cadance blinked. “Okay, no, maybe not. But we’ve been looking forward to this for weeks!” She popped open her bottle. “This is Auntie Celestia’s personal spiced apple cider, fresh from Sweet Apple Acres in southern Equestria. Do you know how long it took me to sneak it out from her booze cellar?” She leaned forward. “Do you know how many guards I had to blow?”

Shining gripped the bottle so hard it nearly cracked. “What?!”

Cadance giggled. “Just kidding.” She wiped her cheek, and for a split-second Shining could have sworn he saw something white on her hoof. “Probably.”

Shining tried and failed to smile. “Hah. Very... very funny.”

“But wouldn’t that be hot, though?” Cadance asked. She grabbed her bottle and ran her hoof up and down its long, hard exterior. “Just imagine me getting caught stealing booze. I beg the guards not to tell, and they force me to suck them off, and then maybe they call some of their friends and they pin me against a wall and just rut me—”

“Sweetie, please.” Shining’s cheeks were tinted green. He swore he could still feel Twilight’s lips on his cock. “Can we maybe not talk about sex right now?”

“Huh? Oh, sure...” Cadance furrowed her brows. “What’s wrong? You’re usually so into my fantasy stuff.”

“I’m just not in the mood,” Shining said, wringing his hooves. “I think I might have a cold.”

“You poor thing!” Cadance said. She patted his hoof. “Don’t worry. I know just the remedy for winter colds.” She pushed his bottle towards him. “A good drink.”

Shining took a sharp breath—but, with Cadance’s eyes boring into him, he uncapped his bottle and took a hesitant drink. The cider went down hot, and kept burning even in his stomach. And yet, it tasted... good? Was good fire a thing? He smacked his lips a few times and thought about asking, but eventually decided to just take another drink.

“There you go,” Cadance said. “Not so bad, huh?”

“No, I guess not.” Shining chuckled. “Still illegal, though.”

Cadance placed one hoof over her heart and threw the other into the air. “By the power vested in me as Princess Mi Amore Cadenza, Royal Sovereign of the Nation of Equestria, I declare you pardoned of your crime.”

“Really?” Shining asked. “You can just do that?”

“I dunno. Maybe?” Cadance bit her lip and leaned into Shining. “But even if I can’t—there’s nothing wrong with getting punished every once in a while, right?”

Shining tried to respond, but before he could get a word out, a familiar tingling warmth surrounded his cock. Feeling himself getting hard for the third time that night, he groaned. “Come on, I thought you promised...”

Cadance gave a sheepish grin “Right, sorry. No more sex jokes.”

“No, no I meant—” Shining looked up and noticed that Cadance’s horn wasn’t glowing, but the magic on his cock remained. He closed his eyes and tried to focus on the feeling. It felt familiar, yeah... but it didn’t feel like Cadance.

He looked over Cadance’s shoulder at the doorway. It was there that Twilight sat smirking, her horn alight.

Shining almost screamed. Eyes flitting between his two lovers, Shining felt a bead of sweat form on his brow, and a bead of precum form at the tip of his cock. Twilight ran her magic up and down his shaft, jacking him off under the table. Every pulse of her magic came with a pulse of pleasure—pleasure which only turned to fear when he looked at Cadance.

“Shiny, you look like you’re about to be sick,” Cadance said, frowning. “Are you sure this is just a cold you have?”

“I’m sure,” Shining stammered as Twilight sped up. He shot his little sister a pleading glance, but her smile only grew. Curses rising in his throat, he leaned over and slid a hooftip across his throat, motioning for her to stop. She fondled his balls.

“What are you doing?” Cadance turned around and saw Twilight, who just waved. Cadance giggled and waved back. “Twily! I was wondering when you’d come out of hiding again.”

“I’m starting to wish she’d go back into hiding,” Shining seethed. Twilight poked his ass with a magic tendril and he winced.

“Oh, don’t be like that,” Cadance said. “You two have such a good relationship. You’re closer than any siblings I’ve ever seen!”

“Yeah,” Twilight said, nodding. “I love my brother. More than anything.”

Shining felt himself reaching the peak. With a start, he realized: the way they were positioned, if he came, he’d be shooting his load all over Cadance’s stomach and crotch.

“Gotta use the bathroom,” he said, leaping from his seat. Feeling the magic on his cock disappear, Shining ran out of the room. He pushed past Twilight.

As he ran, he heard Cadance yell to ask him if he was alright, followed by a curt response from Twilight: “I’ll go check on him.”

“Shiny?” Twilight called, walking up the stairs. The party still raged on below her, but up on the second floor, all was still. The hallway was dark, the only light coming from the bathroom, the door of which was ajar. Twilight crept along, trying to make as little noise as possible before poking her head into the bathroom. “Are you in here?”

She arrived just in time to see a thick rope of jizz fly from Shining’s cock and splatter onto the tiled floor. Her older brother sat against the wall, both hooves clamped to his twitching rod. He let out a tiny moan with the next spurt and let his tongue fall out of his mouth.

It took every bit of restraint for Twilight to not dash forward and lick him clean, or to not catch his jizz with her magic and drink it from the air. Feeling her nethers growing warm, she walked in and closed the door.

“Enjoying yourself?” she asked.

Shining allowed his cock to calm down, then affixed her with a sharp glare. “No.”

His eyes sliced through Twilight’s skin like spears. She forced out a laugh. “What do you mean?”

“I mean that you’re fucking insane,” Shining said. He grabbed a few sheets of toilet paper and began cleaning up. “Trying to molest me in front of my marefriend? What’s wrong with you?”

Twilight’s mouth went dry. She shook her head. “Nothing’s wrong with me. I’m not insane. How could you say something like that?”

“Because it’s true! You’re, like, a nymphomaniac or something!”

Twilight scowled. “Don’t pull that on me. You’re the one who started all of this! You told me you thought I was ‘hot.’ So, what? Were you just lying?”

“Of course not!”

“Then why are you so mad?”

“Because we can’t be together!” Shining said, stomping a hoof. “Not ever! And you trying to break me and Cadance up isn’t gonna change that.”

“I’m not trying...!” Twilight gritted her teeth, eyes stinging. “I’ve been away for four months. Do you know how lonely it is at school?”

“Yeah,” Shining said, rolling his eyes. “You go to a school of seven-thousand. Real lonely.”

Twilight felt like her ribs had been kicked in. She didn’t even try to hold back the tears as she sputtered, “I just want you to love me like I love you.”

“I do love you, Twily!” Shining said, voice cracking. “I love you so much I can barely stand it! But nopony is ever gonna accept that. If we get found out, do you know what’ll happen? I’ll get barred from the Royal Guard. You—you’ll become a laughingstock! Nopony is ever gonna respect a unicorn that sleeps with her brother!”

“I don’t care!” Twilight roared. “You’re everything to me. If I can’t have you, then I... I don’t know what I’m gonna do.”

Shining stared at his hooves. Then, with a deep breath: “We can’t keep doing this.”

“Huh?”

“We can’t keeping having sex, or being in a relationship, or whatever.” Shining closed his eyes. “It’s just gonna keep causing problems. By the time all this is over, we’re just gonna end up hating each other.”

“What?” Twilight choked out. “What are you saying?”

“I’m saying we should forget that we were ever together,” Shining said. Head down, he walked past Twilight and out of the room. He slammed the door behind him.

Twilight was alone. She stared straight forward at a crack on the floor and tried to stop crying, she had to stop, only fillies cried and she was a mare, she needed to stop crying—but she could only clench her teeth for so long before a sob crawled up her throat and slipped past her lips.

She collapsed against the wall. The tiled floor was like ice against her skin as she shuddered.

Shining Armor screamed.

He buried his head in pillows and screamed at the top of his lungs, until his throat burned, until his jaw ached. Head pounding, he beat his hooves into the mattress once, twice, ten times—then went limp. Sweat covered his coat. He sparked his horn and pulled the sheets over his body.

His eyes burned, but he clenched them shut and pushed the sorrow down his throat. Yet, no matter how hard he pushed, it only came raging back, laced with nausea.

The mattress still smelled like musty old books.

“Shiny, are you okay?”

Shining let out a yelp and jumped away, very nearly falling off his bed in a tangle of blankets and limbs. “Cadance?” he asked, squinting to see in the dim light. “What are you doing here?”

Cadance lit her horn, and all the lamps in the room came to life. “You kinda left me downstairs,” Cadance said, climbing into the bed. She pulled him close. “You looked like you were going to be sick when you ran out! Just came upstairs to make sure you were okay.”

Shining forced a smile. “I’m fine.”

Cadance narrowed her eyes.

“...Okay, I’m not fine.” Shining sighed. “I’m actually feeling like a piece of shit.”

“Mhm.” Cadance touched Shining’s face. “Is this about you and Twilight having sex?”

“No, no, it’s—” Shining jolted up straight. “What?!”

“Well?” Cadance raised a brow. “Is it?”

“How... how did you know?”

“You just told me,” Cadance said with a smirk. “But I had my suspicions. I’m the Princess of Love, Shiny. Love and Blowjobs. I notice these things.”

“Oh Goddess!” Shining grabbed Cadance’s hoof and shook his head. “I swear, I’m so, so sorry! I’m sorry! You have to understand that everything just happened so quickly, and one thing led to another, and I was gonna tell you, really, but I was so scared, and—ugh, I’m a freak!”

Cadance frowned and placed a hooftip over his lips. “Shiny, you are not a freak. I don’t want to ever hear you say that about yourself.” She offered him a warm nuzzle. “It’s okay. I’m not mad.”

“You aren’t?” Shining asked. He moved his mouth around for a few moments before sputtering, “But why? How? I’ve been fucking my little sister behind your back! My little sister!”

“Yes, it’s a bit weird; I’m not denying that. But the heart wants what the heart wants. You’re a teenaged colt.” Cadance laid a hoof on his chest. “Your heart just wants someone who cares.”

Shining flinched under her touch—but nodded.

Cadance simpered. “Also, honestly? It’s kind of hot. I mean, fucking your little sister? That’s kinky! I never knew you had it in you!” Before Shining could respond, Cadance fell onto her stomach and let her wings go erect. “I remember when I was Twily’s age, all I wanted was for Celestia to fuck me. And hard, too. I would have dreams about her taking me to the Grand Galloping Gala, ripping off my dress, and hornfucking me right in front of everyone...”

Shining nodded again, cheeks blazing.

“And imagine if you got her knocked up? Imagine little Twily walking around with your babies inside of her—”

Shining cleared his throat.

“Oh.” Cadance chuckled. “Sorry.”

“What am I supposed to do?” Shining covered his eyes. “Twilight and I can’t keep sneaking around. But we can’t go public, either! I want to just move on, but it’s gonna make Twilight hate me.”

“Twilight isn’t just some floosy you can move on from,” Cadance said. “She’s your sister. The two of you are gonna be around each other for the rest of your lives. You don’t wanna spend that time being afraid of each other. You have to do right by her—and you both need to be okay with it.” She gestured to the door. “So that means not just leaving her to suffer alone. Talk.”

Shining nodded, left Cadance with one last kiss, then got out of bed.

Broken glass spotted Twilight’s carpet, and a smashed picture frame rested against the wall. The picture inside—Shining and Twilight, years ago, sitting together in the snow—was ripped and torn.

Twilight lay on her bed, still as a corpse. She made no sound, no protest as the curt winter air passed over her coat. Below her, the sounds of the Hearth’s Warming party played out. She heard talking, laughing, singing. The sounds surrounded her, seemed to deafen her with their joy.

No, she thought. It seemed to be the only word she could come up with. No. No. No.

The door creaked open. “Twily?”

She found a few more words.

“Get out!” Twilight screeched, voice cracking. “Get out of my room! Get out, get out, get out!”

Shining flinched, but kept walking, kept marching until he reached her bed. She screamed at him to leave, screamed that she never wanted to see him again—but she didn’t resist when Shining climbed into the bed next to her and wrapped his hooves around her small body.

She buried her face into his chest. “I hate you,” she said, trembling.

He brushed her mane. “I love you.”

A low wail broke free from her throat. She grasped at his coat, kicked her hooves weakly into his stomach, all the while sobbing, weeping. Bitter tears spilled onto Shining’s chest, and he held her tight, as if he would never let go.

He pulled her face up and wiped her tears away, then gave her a kiss; Twilight flinched, but returned the gesture.

“Why...?” Twilight murmured between kisses.

“I’m sorry for yelling at you before. I just got so freaked out, I—I didn’t know what to do.” Shining paused. “I still don’t know. I just want to be with you, but...”

“We can tell them!” Twilight said through her tears. “We can tell Mom and Dad and everyone about us. We can run away, and be together forever, and we won’t have to care about what anyone says!”

Shining frowned. “No, Twily. We can’t.”

A fire burned in Twilight’s chest. We could, I know we could.

She closed her eyes and imagined them together. Alone. The years would pass and they would grow old together. Alone. They could start a family. Alone.

Nopony would ever look at them the same way. They’d be known forever as incestuous freaks. Twilight would be giving up all of her dreams to be with Shining—and Shining would be giving up all his dreams to be with her. There would be no going back... even if it didn’t work out. Even if five, ten years down the line they ended up hating each other. No undoing the past.

A hole opened in the pit of Twilight’s stomach. She gritted her teeth. “Yeah. I know.” She looked up into her older brother’s eyes. “But without you, everything just feels so... lonely. Nopony can ever love me like you do.”

“That’s not true!” Shining said, shaking Twilight. “Yeah, I totally love you—but I know that there’s gonna be someone else out there who does, too. You’re the cutest, sweetest filly in the world. Any stallion would be lucky to have you.”

Twilight whimpered. “But I want you.”

“And I want you, too. But it’s not gonna happen.”

Twilight let out another sob and held her brother tight. Shining rested his chin in the top of her head and closed his eyes—but within moments the tears came spilling out, trailing down his cheeks and into the pillow.

In some desperate effort to stifle his own cries, Shining grabbed Twilight and kissed her. Twilight took his offer and pushed back, pressing her muzzle into his. She made no protest as he slipped his tongue past her teeth and into her mouth. Twilight gripped and grasped at Shining’s coat, gasping for air in the split seconds they drew apart.

Warmth bloomed through her body. The two siblings pressed their bodies against one another. Twilight felt Shining’s semi-hard cock against her stomach and she rubbed against it, relishing in the way it pressed into her skin.

Shining moved away from Twilight’s mouth and nipped at her neck, her chest, her side. She whispered a curse as Shining ran the tip of his tongue over her sensitive teats, running his hooves across the gentle mounds—and she very nearly moaned when he flicked his tongue across her engorged lips.

Shining dug his muzzle into her fillyhood, lapping up the nectar that already flowed. Twilight quivered at his touch. Rushing waves of pleasure coursed through her skin, filling the hollow pit in her stomach. She grabbed his hair and pushed him deeper, until his tongue was swiping across her inner walls.

This is it, Twilight thought, biting her lip. Even as Shining ate her out, the stinging in her eyes returned. This is the last time.

She sniffled—but before the tears could fall Shining jumped up and grabbed her shoulders. Twilight didn’t resist as her older brother pinned her to the bed and touched her buzzing horn to his. She barely had time to register the soundproofing spell he cast over the room before she felt the tip of his cock rest against her clit.

He stayed there for a moment, letting out heavy breaths onto her neck. He rubbed his tip up and down her pussy once, twice, again and again until Twilight was twitching, shaking, grabbing the sheets.

“What are you...” Twilight breathed. She arched her back, pressing her head into the pillows and her chest into Shining’s. “Just do—Just do it!”

He slid his cock inside—just an inch or two at first, enough for him to grunt when she winked against him. A second passed, and he allowed her another short tease. He took his time to give her his first real thrust, waiting until she was nearly panting with tension, only to pull out again and hang above her.

“I am,” he said with a trembling smile. “You’re just impatient.”

“Screw you,” Twilight said, laughing. Her entire lower half tingled. “You’re such a—”

He pushed his entire length into her and Twilight could have screamed.

They moaned into each other’s mouths as Shining rammed her. He picked up speed with every thrust, plunging his cock in and out, in and out. Twilight could only paw meekly at his face as her walls clamped down around him. She felt every rough inch of his meat twitching inside of her. Whenever he pulled out, she pushed her hips up a bit, as if chasing his dick.

Shining had no rhythm. For a minute at a time he would take it slow, steady—only to jump a gear and slam his cock into her with the force of a bullet train. Twilight relished every push, every sharp slap of his balls against her hips.

Her entire body burned with a comfortable fire, but it didn’t take long for that fire to grow. The pressure in her loins had been building since he first touched her. With every passing second her breaths grew shorter, her thoughts became mere flashes, her words turned to sputters—not that she had much to say.

“Oh my...!” Twilight bit down on her own hoof and blurbled a string of curses. “C’mon, c’mon, c’mon!”

Shining’s head was high in the air, and every breath came as a primal growl. “Yeah,” he managed, nodding. “I think I—oh, shit!”

Twilight edged open an eye, only to clench it shut again as Shining’s cock jerked against her tight walls, and a blast of jizz surged into her. Shining’s cum spilled through her pussy, out onto the bed, into her womb. For a moment, Twilight felt full enough that she could explode.

With a groan, Shining pulled out of her and rested his dick just above her clit. He let out another splatter of jizz, covering his little sister’s teats and stomach. A few more short spurts flowed out onto Twilight’s crotch and dribbled down her cunt. Shining collapsed and let his still stiff penis press into her pussy.

The pressure in Twilight’s nethers stood at its peak. Every sense was on overdrive. All she needed was one more touch.

So when Shining’s coarse fur dragged against her jizz-covered teats, when his cock gave one last twitch, she saw stars.

“Hoooooooooly fuck,” Twilight roared at the ceiling. The orgasm leaped upon her like a wave—a slow rush, followed by a pure, indescribable feeling that slipped through her veins, danced along her skin quicker than she could comprehend. Thoughts rushed past without stopping. She felt pussy juice rush out in one burst, drenching her brother’s dick once again.

With that, Shining rolled over, slumping into the bed next to Twilight. The siblings took loud, gasping breaths. They didn’t waste any oxygen on speaking as they moved closer.

Twilight curled up against Shining’s chest and smiled at the way their warmth blended together. Shining kissed Twilight’s forehead and wrapped her in an embrace.

“That was pretty good, right?” Shining asked in a breathy voice. “Like, a grand finale, or whatever.”

“Yeah,” Twilight said. Her voice was cracking, but she still smiled. “It was pretty good.”

The two stayed silent for a minute.

“Do... do you think we should tell Cadance about this? About us?” Twilight asked, frowning. “Oh, gosh, she’ll be so freaked out...”

Shining blinked. “Uh. About that...”

About half-an-hour later, once Shining and Twilight had cleaned the jizz from their coats—and Twilight had recovered from her embarrassment-induced panic attack—they trotted downstairs, only to be greeted by their mother’s glare.

“Where in the world have you two been?” Velvet shouted as soon as they entered the living room. Only a few guests remained, and even they seemed to be preparing to leave. “You’ve missed the entire party! Do you two know how rude it is to just hide away like that?”

Twilight flinched. “Sorry, Mom. We were just... talking.”

Velvet snorted, then turned to Shining. “And you—you just left poor Cadance all to her lonesome. Let me tell you something: that is not how I taught you to treat fillies.”

“Yeah,” Shining said, ears going flat. “I know. Sorry.”

“I don’t think I’m the one you need to be apologizing to,” Velvet said. She walked away. “Don’t think you two are getting out of clean-up duty!”

Ears still drooping, Shining turned to Twilight. “Uh, hey. Do you mind if I...?”

“Go,” Twilight said, waving him off. “She’s your marefriend. Not my rival.” She paused, then tittered. “At least, not anymore. And besides, I’m not sure I can even look her in the eyes anymore...”

Shining shared her laugh, then nodded and headed off. He found Cadance in the same spot he had originally left her, sipping at cider in the kitchen. By the looks of it, she had gone through at least four bottles already, and a reddish flush had filled her face.

“Hey,” he said when he sat down, offering a sheepish smile. “Sorry I was gone for so long. We, uh, y’know.”

“I know,” Cadance murmured. Her lips screwed up into a smirk. “You’re pretty cute sometimes, fillyfucker.”

Shining’s eyes went wide. He pulled Cadance close and leaned into her. “I am not a—”

“I’m just kidding, fillyfucker—Shiny,” Cadance said. She planted a hearty kiss on his lips, and gave a full-bodied squeal when he flinched. “Oh, you’re such a little nerd and I love you so much and oh my gosh!”

“Uh, Cadance... are you feeling alright?”

“I’m feeling totally alright. In fact,” Cadance said, wrapping her magic around Shining’s cock and massaging the tip, “I’m feeling better than alright. Like maybe I’m up for some fun.”

Shining gulped, wincing with every stroke Cadance gave. His dick ached from the savage fucking he had given Twilight, but even so, he probably had enough left in him for one more round...

“Too bad I gotta get home,” Cadance said. She released Shining’s dick and hopped out of her chair. “I told Auntie Celestia I’d be back before midnight, and if I get back late and she catches me and she smells all the cider on me—it’s not gonna be good.”

“I get it.” Shining climbed down from his chair and finally returned her kiss. “Thanks for being so understanding and stuff. Tonight’s been freakin’ weird.”

Cadance smiled and touched her horn to his, creating a tiny pink spark. “It has. But everything’s gonna be okay, Shiny. Everything’s gonna be fine.” She took a few steps toward the doorway—then spun around and, with a grin, whispered into Shining’s ear, “By the way, cumming on her little teats? Hot.”

“What?” Shining yipped, stomach crumpling. “How did you—?!”

“I know lots of temporary age spells,” Cadance said. She blew a hot breath down Shining’s neck. “How young do you want me? Fifteen? Thirteen? Ten? You want to fuck a ten-year-old, Shiny? I can cover up my cutie mark and everything.”

“I...”

“I just want you to fuck me as hard as you do any other little girl,” Cadance said. “You wanna get a filly pregnant? I’m ready.”

Shining clenched his teeth. “I’m not getting anypony pregnant.”

“You sure?”

“Of course. Twilight has that weird anti-pregnancy spell of hers. I dunno how it works, but it does.”

“Spells can always fail.” Cadance left Shining’s neck with one last nibble, and his cock with one last stroke before turning away and heading out. “If I were you, I’d tell Twilight to start casting that spell twice!”

That sent Shining back to his haunches. He sat there for a minute, thoughts pounding, before shaking his head and heading back to the living room. She’s just joking. Cadance likes jokes.

Twilight was over in the corner, picking up empty bowls and wine glasses. Just as it seemed like her magic would fail under the weight of all the items she carried, Shining rushed over and took half the load. Twilight offered him a begrudging thanks—“I could have carried all that, you know.”—and Shining joined in with the cleaning effort.

“Say, Shiny,” Twilight began after a few minutes, her eyes cast to the ground. “I’m... I’m sorry for acting so crazy these last few days. I always read about how corrupting hormones are, and I guess I should have probably figured it out the first time I fucked my older brother in a bathtub, but I never realized how awful I could get. I’m sorry, really.”

“It’s fine,” Shining said. “Just... upstairs, that was the last time we’re ever gonna do that. It has to be. We have to move on.”

“Ugh, don’t even talk about it. At least you have Cadance. I’m just gonna have to go back to school alone.”

“I know I meant it as an insult before, but you do have quite a few classmates.” Shining elbowed his sister. “I’m sure you can find a coltfriend if you really try.”

“I probably could.” Twilight spent a moment tapping her chin, then shrugged. “Nah, too much work. I’ll just buy a dildo.” Shining went stiff, and she laughed. “Joking. I guess I could try to find a coltfriend, yeah. But then again, that would mean actually talking to colts. That seems... risky.”

“You do just fine around me.”

“Yeah, but you’re different. You’re—” Twilight bit her lip. “Sorry. Not gonna obsess anymore.”

“You’ll be fine, Twily.” Shining leaned to the side and kissed Twilight’s forehead.

A flash went off behind them.

“Oh, Grandma Sparkle will love that picture!”

Dear Shining,

Happy National Teen Literature Day!

...Yeah, I know that’s not much of a holiday. But I’ve started interning at the campus library, and we take our literature-themed celebrations quite seriously.

How are you? It’s been a while since I’ve sent you a letter—I’ve been trying to focus more on talking to colts around here. There are quite a few that hang around the library, but I admit, I don’t find any of them particularly appealing. I was talking to a stallion by the Ancient Griffon Literature section the other day, and get this: he didn’t know the original publishing date of King Blackbeak’s Treatise on Animal Husbandry. What kind of book lover doesn’t know that?

As such, I find myself suffering from a rather meager sex life. I haven’t actually been with a colt since you. My friend Lyra knows some spells to give mares penises, and we experimented with that a little bit, but Lyra is a little too rough and cries after she has sex, so I’m not sure I’m prepared to deal with that every night.

I miss you. I’m not gonna deny that. But I’m trying my best to move on. For both of us.

I hope Cadance is doing well. Tell everyone I said hello.

Love,
Twilight Sparkle

P.S.: Have you ever had pickles with vanilla ice cream before? I know it sounds disgusting, but I’ve just had these intense cravings for it recently—weird, huh?
