Shining Armor sat, recovering on the couch. Twilight Sparkle and Princess Cadance on either side of him. Her final feat of magic completed, Trixie took a bow and began to pack up her things back into her magic trunk.

"Um, Miss Trixie?" Cadance asked. Trixie paused in her clean-up. "I was actually hoping that a certain... pair of boxes would make an appearance this evening." Twilight and Shining exchanged knowing glances. "Of the... cutting-a-pony-in-half variety?" Trixie shuffled her hooves nervously. "Do you still have them?"

"The Great and Powerful Trixie... does have them... but she does not employ those in her acts. Exotic or otherwise," Trixie said.

"She does tonight," Cadance said, with a mischievous smile. She trotted into the bedroom and returned with a ceramic pig. "I'm buying them from you." Cadance broke the pig on the floor, collecting the bits inside into a pouch.

"Aww, Pigly 2," Shining whined. Cadance placed the pouch into Trixie's hooves. Trixie stood there for a moment, unsure of how to respond. Cadance's smile didn't waver. It was bore of utter confidence, in telling her that the boxes would be used tonight. It was neither a threat nor a promise. She was merely saying what was going to happen next. One way or another.

"Trixie... needs a few moments," Trixie said, lugging the trunk back out to her caravan. Twilight watched from the window as Trixie dug through the back of her traveling caravan. It didn't seem terribly large, but with the amount of stuff that Trixie was pulling out of it to get to the notorious boxes, Twilight would swear that it was somehow bigger on the inside.

At last, she pulled out the two familiar boxes, returning all the other items inside before bringing them down the path to the beach house. About half-way down, she stopped. Not for any apparent thing, in particular. She just sort of, stopped, and stood there. Frozen for a moment. She stood and stared at the ground for a moment. She wiped her eye, of dust, Twilight assumed, before shaking it off, visibly trying to calm herself and get back into character. Her stage persona, Great and Powerful. Twilight scampered back to the couch. The door flew open as Trixie strutted confidently inside.

"Back by popular demand, The Great and Powerful Trixie has deigned to grace her audience with an encore performance! Cutting a pony in half!" she announce into the room, louder than was explicitly necessary. As she brought in the two enchanted boxes, Cadance clapped her hooves excitedly as Twilight and Shining remained reserved. "For this trick, Trixie will need a volunteer from the audience." Cadance threw her hoof into the air as far as it could go while still being attached to her torso, waving it like an ecstatic filly.

"Ooh! Ooh! Pick me!" Cadance said. Shining and Twilight were each practically sitting on their hooves. Trixie scanned the room, squinting and rubbing her chin with her hoof in faux contemplation.

"Hmm, how about... YOU!" Trixie decided at last, pointing at Twilight Sparkle.

"Aww!" Cadance complained. Twilight remained put. Cadance gave her a couple of shoves, forcing her to her hooves. Twilight begrudgingly walked to the 'main stage' of the show. She was about to climb into the box when Trixie levitated her into the air, placing her in the box herself. Had it been any other unicorn, Twilight wouldn't have been surprised.

"Watch in awe, as the Great and Powerful Trixie bisects a pony in half!" she said, brandishing her comically-large saw menacingly, making a vague sawing motion at the corner of the box's midsection. She levitated forth the two metal plates, sliding them through the middle of the box, triggering the enchantment. "Presto, Change-o, Rearrange-o!" Trixie tapped the box with a wand, and with that, Trixie pulled apart the two halves of the box. Cadance was giddy on the couch, bouncing up and down in her seat with excitement. Trixie hid her flattered blush behind her sliver mane's locks. Her hesitation to use the boxes began to fade amid the fanfare she was now receiving. She strutted between the two halves of Twilight with a flourish of her cape.

"Me next! Me next!" Cadance said.

"Okay Trixie. Put me back together now," Twilight said.

"What's the matter Twilight? Are you having a little..." Trixie shoved Twilight's lower half rolling away on the box's wheels into the kitchen, "separation anxiety?" she chuckled and opened the other box. "Your Highness," she invited Cadance into the other box. Cadance trotted over and Trixie levitated her, helping her inside and closing the lid. She repeated the act. "Presto, Change-o Rearrange-o!" She pulled apart the two halves of Cadance.

"He he!" Cadance giggled as Trixie spun her around to see her other half, separated from her.

"Ah, but the best is yet to come!" Trixie said, walking into the kitchen to fetch Twilight's other half. She shuffled the boxes around a little to try to generate some dramatic confusion. Twilight tried to keep her motion sickness at bay. "And now to reattach the halves together!" Cadance looked over at Twilight beside her, neither able to see their lower half. "Presto Change-o, Rearrange-o!" Trixie tapped the boxes with her wand and sprung the lids open. Cadance and Twilight each climbed out of the boxes. Twilight saw that, predictably, Trixie had swapped their halves. Twilight looked back at Cadance's lower half, attached to her. And Cadance hopped around in a circle, eyeing her flank like a filly that had just gotten her cutie mark.

"Twilight, look!" Cadance said, shaking Twilight's flank at her. Twilight wasn't paying attention. She could feel her face getting warm. Her brow began to develop beads of sweat. She was panting. "Twilight are you okay?" Cadance asked. Twilight had been staring at the carpet with her tongue practically hanging out. "Twilight?" Her violet eyes slowly looked up at Cadance, her head following.

"I- I feel all... googly," Twilight said in a husky voice.

"Googly?" Cadance tilted her head in confusion. Twilight nodded slowly.

"I- my- your half feels- really turned-on!" Twilight's flushed face turned a deeper crimson in embarrassment.

"Oh," Cadance thought for a second. "I forgot that I was in heat."

"This is what your heat is like!? How do you live like this!?" Twilight breathed.

"I don't know. I just have a really high sex drive. I guess I've just gotten used to it. Plus I was still warmed up from Trixie's 'magic wand'," she answered. Shining got his sister a cold glass of ice water from the kitchen. "Ooh! You need to switch me with Shining!" Cadance said to Trixie. "I need to know what it's like to have a penis!" Cadance said.

"As you wish," Trixie complied, levitating Shining away from Twilight.

"Hey!" he tried to protest as she put him one of the boxes, and Cadance in the other. Trixie spoke the magic words and swapped the halves. Twilight was still dealing with having Cadance's flank. So when Candace hopped out of her box with Shining's half, Shining once again found himself with Twilight's flank. "Just like old times," he thought to himself. "Oh, what the hay are you doing!?" he said. Opposite him, Cadance had managed to quickly give herself half an erection. She was hopping up and down on the couch like a trampoline, causing it to swing around like a windmill.

"Ha ha ha! It feels just as funny as it looks!" Cadance announced, shamelessly showing off her new dick. Twilight was practically foaming at the mouth, unable to tear her eyes away from her brother's dick, flailing wildly before her very eyes. For years, her desire had always been there. But now, in her present state, it was a raw, wanton need.

"Somepony needs to fuck me right now!" Twilight shouted. Shining and Trixie both froze in shock. Cadance ceased the jumping on the couch. The whole room went stock still.

"Whoa. Easy kiddo," Shining said after a moment, breaking the silence. Cadance trotted over to her, putting a hoof around her.

"Hey now, you're all right. You just need to take a deep breath. You just need to-"

"I need to get rutted!" Twilight practically growled, "Immediately, if not sooner!" She turned and all but pushed Cadance onto the floor, ready to straddle her erection.

"Twilight! Trixie is right there!" Cadance said. Trixie rolled her eyes.

"Pssh! Nothing I haven't already seen." Twilight neither heard nor cared about what Trixie said. She was entirely focused on Cadance. On the penis she had. Shining's penis. She began to grind her marehood against it. Her whole world was consumed in it. Her every thought was bent on it. She could feel every bump and ridge of its veiny texture against her borrowed pussy. She needed it, so badly it hurt.

While Trixie was otherwise indifferent, Shining couldn't help but stand and stare at the spectacle before him. A mare's parts though he had, a stallion's brain he kept. And he was simply incapable of interrupting two mares in the throes of lust. But as visibly aroused as Cadance was with her erection, she was still somewhat hesitant to Twilight's sudden aggression.

"Twilight, come on, stop acting like this! It can't have been that long since the last time you've gotten any," Cadance said. Twilight blinked. Her eyes focused for a moment in lucid thought, shifting from looking at the dick she was straddling, to briefly looking into Cadance's eyes before looking away again. Cadance's eyes went wide in realization. "No-" Cadance gasped. "This whole time?" Shining looked confused.

"What?" he asked, waiting to be let in on whatever was going on.

"Twilight, when we broke up, I thought it was because you already had somepony else in mind," Cadance said. Twilight glanced over at Shining. Cadance's eyes followed hers. "Oh. Right," she trailed off. "So there's been nopony since then?" Twilight shook her head. "Oh, Twi..." Cadance propped herself up, wrapping her hooves around Twilight in a tight embrace. It was the same comforting hug she had given her when she had been hurt as a filly.

Twilight could have cried, but she didn't. She wouldn't let herself.
She had cried enough today.

Cadance laid back onto the floor, pulling Twilight down with her, never letting her go. Twilight hugged her back, pressing her face into her creme colored mane. Her scent brought the same soothing memories as it always had. All of them sweet, but the last one. The bittersweet goodbye of losing her as a marefriend. Twilight lifted her face from Cadance's mane, looking into her eyes. She remembered what they had talked about earlier.

"I'm sorry I pushed you away."

"Hey, you didn't push me anywhere. I'm still right here."

Cadance was right. She was still right there for her. Even after Twilight had thought that she had pushed her away, she still held onto those feelings for her, just as Twilight had for Shining, in a vain hope against all hope. Somehow it had all worked out. It was right there in Cadance's eyes. At first Twilight only saw the sympathy for her loneliness, but behind that, just at the corners, was a glint of joy. She had Twilight back, in the way she had so verily longed for. The ache in Twilight's heart melted away and she smiled, leaning down to kiss her. Cadance kissed her back.

It wasn't a sloppy, rushed kiss of lustful passion. It was slow, and strong, the way mares kiss their stallions returning from a long guard deployment. It was the catharsis of all the fear and doubt of each ever seeing the other again. Both a celebration and reaffirmation of their love. Their hooves held each other tighter, their legs intertwined as they pressed themselves into one another, horns brushing together. It was as though their entire bodies were kissing, reunited as lovers after so long.

Twilight could feel Cadance's erection growing back to full mast, sandwiched between them. She squirmed a little against it, remembering how sensitive it could be. It forced Cadance to break the kiss and gasp. Twilight smirked, pleased with herself in showing her elder lover a few new tricks herself. Unable to ignore the ache in her loins any longer, Twilight shifted herself up Cadance's body, letting her erection spring free, upwards behind her.

Twilight's copious arousal had already expedited the lubrication of each of them from her earlier grinding. In a teasingly slow movement, Twilight eased herself backwards against Cadance's poised shaft. The tip slipped and slid against her wet folds, causing Cadance to shiver as she probed at Twilight's entrance. With her last scrap of clear thought in her haze of lust, Twilight had the presence of mind enough to cast a contraceptive spell on herself. The very instant it completed, Twilight shifted her weight. The pressure pushed past the threshold of resistance and Cadance entered her at last. Both mare cried out in pleasure.

Shining was only too happy to watch Twilight seat herself on Cadance's lap, taking the length of her shaft completely within her. But while he was content to let them intermingle, Trixie began to grow impatient. The evening had taken several unexpected turns. Her high hopes that came with Twilight's appearance for another chance with her were evaporating before her very eyes as the two mares made love on the soft carpet.

Trixie looked over at Shining, sitting on the couch beside her. She hadn't had any real attraction to him before aside from him being Twilight's brother. Her gaze drifted lower to Twilight's half, attached to him. He was preoccupied with watching the other two going at it. "When would she have another opportunity?" she wondered.

"Abracadabra," Trixie said, pulling one of his purple legs toward her with her magic, "Gonna reach out and grab ya."

"Hey!" Shining yelped in a pitch higher than he was expecting, as she pulled him across the couch to her, taking his legs in her hooves, getting a good look at Twilight's marehood on him.

"Mmm, I've missed you," Trixie said, licking her lips and running her hooves up his inner thighs.

"Cadance!" He cried out. Cadance meanwhile, had her hooves on Twilight's waist, bucking her hips up into hers from below. Even if she had heard him over the wet slapping of their fucking, she clearly couldn't be bothered to care about anything else in the world at that moment aside from fucking his sister with his own dick. Indeed even if the house was on fire, she would at least try to finish before fleeing the danger. And just by judging from the look in Twilight's eyes, the heat from the friction in her loins might almost be enough to cause just that. "Twi!?"

"Oh, quit your whining, you big baby," Trixie scolded, lowering her head between his legs, taking a deep breath of Twilight's musk, "don't pretend that you aren't going to enjoy this too." Trixie ran her tongue up along his slit. Shining gasped and gripped at the cushions of the couch, struggling to squirm. Trixie wrapped her hooves around his purple thighs, holding him tightly as she dove in with gusto, licking up and down along his folds.

The sound of something breaking made Shining look back over his shoulder. At some point, his wife and sister had rolled over, with Cadance on top now. They had bumped into and end table, knocking over a lamp. Cadance's had Twilight's legs over her shoulders as she really started to give it to her. Twilight's entire body rocked each time Cadance slammed it home into her, smacking her balls against her ass. Twilight could feel the pressure building in her tummy, like a knot being pulled tighter. Cadance's pelvis collided with her marehood a few more times, sending her over the tipping point.

"Ah! AH! AHHhhhh!" Twilight cried out, practically shaking as she came. Cadance felt her pussy spasm around her cock, rippling and gripping her even as she continued to fuck her. Her juices spurted out around her shaft, filling the room with the heavy musk of her marecum. Twilight shuddered and fell limp on the floor, exhausted from the exertion of her orgasm, leaving her leg still twitching. Cadance smirked. Twilight had clearly been unprepared for the sheer awesomeness that was Cadance's orgasms. Mercifully, she let her rest, gently withdrawing from Twilight.

Trixie's horn glowed as she played with herself, stretching and probing her dripping wetness with an ethereal phallus. Her face was still buried between Shining's legs. She was reveling in the taste of Twilight's marehood as he squirmed and writhed from her ministrations. She flicked his clit with her tongue, giving it little sucks as she rubbed the rest of his marehood with her free hoof.

She did not see Cadance approach.

Trixie cried out, muffled into Shining's crotch as Cadance mounted her from behind. The surprise interrupted Trixie's focus, causing her magical dildo to vanish. That was just fine for Cadance who thrusted forward without hesitation, penetrating her thoroughly-warmed-up pussy. Cadance grabbed her blue horn with her hoof, pulling her head back, "GAH!"

"You think you can just go down on my husband like that and get away with it?" Cadance whispered harshly into Trixie's ear. She pushed her cock all the way inside her, making her groan. "Well then, you better make sure he cums... before I do!" Cadance gave Trixie's horn a slow, lascivious lick before pushing her face back into Shining's crotch.

Trixie wasted no time, redoubling her efforts on the semi-stallion, using every trick she could remember. It was super effective on the pony not used to having a marehood. But even as long as it had been, he clearly recognized the approach of his feminine climax.

"Ngh! Oh! Ah!" he moaned out. Twilight recovered herself from her post-coital bliss and shuffled over to the commotion on the couch. She took his head in her hooves. His eyes crossed as he looked up at her, standing over him. Just in time to see her take his horn into her mouth. She sucked and licked with as much competitive fervor as the azure mare at the opposite end of him. Trixie repeatedly shoved her face into his pussy. Or rather, she had her face shoved into his pussy each time Cadance bucked into her. The duet of pleasure was too much for the pony already on the edge.

"NGHaaaah!" His hips bucked against Trixie, even as Cadance continued fucking her at the other end. Twilight released his horn, letting the sparks of his horngasm evaporate into ozone. Trixie gasped for air, trying to keep from drowning in the rush of fresh nectar. She could feel Cadance's bucking growing more forceful and erratic, heralding her own orgasm.

"Please no!" Trixie cried out, "You said you wouldn't if he came first!" Cadance's chuckle started as a low rumble before erupting in a full bout of laughter.

"I said no such thing!" Cadance said, "This is my first time with a cock, and I will cum wherever I please!"

"Just do a contraceptive spell," Twilight said.

"Trixie can't! I- I don't know how!" Trixie cried, trying to pull away from Cadance. But the larger pony held her firm.

"You were in the same class as me when we learned it in Magic School!" Twilight said in annoyance, "You don't remember?"

"N- no!" Trixie whimpered. Twilight leaned over her brother, bringing her face an inch away from Trixie's. Trixie looked up a Twilight, half expecting her to kiss her or something. She could feel Cadance's cock beginning to flare inside her.

"If only you knew real magic," Twilight said with a smug grin. Trixie's eyes flashed with burning anger.

"Unf unf ngh!" Cadance grunted as she felt her balls tighten. She slammed it home one final time as her cock began to throb and twitch inside Trixie. Twilight's horn glowed as the first load of cum rushed up Cadance's shaft, flooding Trixie's vagina.

"Nooo!" Trixie cried in defeat, clenching her eyes as she felt herself being filled with seed. She did not see Twilight finish casting the spell on her. Cadance's flared head stretched Trixie's insides wide, forcing her cervix to slightly part open. Cadance continued to pump load after load into Trixie, pushing it deeper inside her with her cock. Trixie felt her belly distending from the pressure of an impossibly large load. Even Cadance was surprised by the duration.

"Shining!? Did you drink that fertility potion already?" Cadance asked.

"Yeah. I was thirsty and the cider in the fridge wasn't cold yet," he said. Cadance rolled her eyes, holding Trixie fast as she kept pumping cum deep inside her.

"YAAHH!" Trixie shrieked in pain and terror, fearing she would burst at any moment. Cadance released her hips, letting Trixie fall forward onto Shining's chest. She pulled free of Cadance's dick with a wet 'plop', forcing pints of cum to rush from her abused pussy, audibly gushing out in a white torrent. It sprayed onto the couch, and floor, and soaked her silver tail in hot, sticky cum.

"OOOHHHGGGHHH!" Trixie let out a deep, throaty moan of relief as the tremendous pressure inside her was finally released.

After a few moments, Shining extricated himself out from under Trixie, who was barely skirting the fringes of consciousness.

Trixie blinked her eyes open. It was dark. And she was outdoors. She way laying in grass. She realized that she was laying on the front lawn of the bungalow, dressed in her hat and cape. Twilight was sitting on the stoop of the doorway nearby. Her top and bottom half matched. She must have restored herself while Trixie was out.

"Hey," Twilight greeted. Trixie furrowed her eyes and sat facing away. She could see that her wagon had already been neatly packed as well. "You really don't know a basic contraception spell?" she asked. Trixie said nothing, still facing away. "I did cast one for you, so you'll be fine. I mean, I only ask because it seems like it would be kind of important to know one in your line of work as a.... whorse." Twilight trailed off. Trixie whipped her head around.

"The Great and Powerful Trixie is NOT a whorse!" she spat.

"Maybe you don't understand the definition of the word. But you just had sex for money," Twilight said.

"Trixie is a performer! I do magical illusions!"

"Erotic performances with dildo wands?" Twilight asked.

"Do you really think that Trixie can do normal magic shows after the debacle in Ponyville with that Ursa Minor!? I've been the laughing stock of Equestria. I've had to make money somehow."

"By eating out my brother?"

"THAT WASN'T-" Trixie tried to calm herself, "That wasn't for money."

"Oh, sure," Twilight said sarcastically, "You were just hungry. I'm sure Cadie has some snacks in the fridge if you're that desperate." Trixie glared at her. "Was it an accident? You slipped and fell face-first into his pussy then? Whatever. It doesn't matter what you do. I'm just saying that whatever... line of work you do, knowing some real magic might be good for you."

"Trixie DOES know real magic!"

"Whatever you need to tell yourself," Twilight sighed. "I'd recommend that you find another line of work that doesn't require magic. I hear Pinkie's rock farm is hiring." Twilight stood up and opened the door. "I'm going inside. Goodbye Trixie." Twilight walked inside and closed the door behind her. Trixie fumed, standing there in the grass. She wanted to yell. She wanted to cry.

"Trixie will show you!" she growled, stomping back to her wagon. "Trixie will show everypony!" Inside, Twilight saw Shining on the other side of the couch, standing by the window of the living room, peering out through the blinds. The two enchanted boxes that Cadance had bought from Trixie were still in the living room.

"What did you say to her? She looked furious," he said. Twilight considered the answer, coming to a sobering realization.

"I might have, kind of, sort of called her a whorse and questioned her ability to wield magic."

"Yikes. Savage," he said.

"Well, yeah. I realized that now."

"I think she had, or still has feelings for you."

"You think that's why she... did that with you?" Twilight asked.

"Could be. But who knows. Mares are crazy." He paused for a moment. "You know, if you'd said that to somepony else, they might devote their existence to exacting revenge."

"I'm not worried about her," Twilight said. "I mean unless she somehow manages to find some kind of amulet that magically increases her power."

"Yeah right," Shining laughed, "the likeliest of scenarios!" Twilight laughed with him as he walked out from behind the couch. She looked him over. He now had Cadance's lower half, marehood dripping with fresh semen.

"Where's the rest of you?" she asked. Shining blushed.

"She's um, not done using it yet," he said.

"Hey!" Cadance shouted from the bathroom, "Come see how far I can stand from the toilet! He he! Whoa, whoops! Down boy!" Shining blushed and put his hoof to his face.

"Sounds like somepony I used to know, growing up." Twilight smirked. Shining blushed harder, guilty. She sauntered over to him, nuzzling his cheek with hers. "I'm heading to bed."

"You're going to sleep already?" he asked.

"No. I'm going to bed." She winked at him. "Maybe when you get your other half back, you'd like to join me?" He smiled back, giving her a kiss. He kissed him back harder. He let her. After a few moments, he broke to catch his breath.

"I'd like that, actually," he breathed, and kissed her again. "I'm... " He wrapped his hoof around her waist, hugging her tightly. "I'm sorry it took so long for me to realized it." She hugged him back.

"Well you can make it up to me tonight." She kissed him again. "And tomorrow night, and the night after and the night after..." she trailed off, flicking her tail at him as she walked to her bedroom. Shining could feel his heart flutter in anticipation.

"Honey!?" he shouted toward the bathroom, "I'm going to be needing that back now!"

A Few Years Later

"HOO HOO HOO HOO!" Shining huffed and puffed in the hospital bed. Cadance was sitting beside him, holding his hoof.

"You're doing great honey!" She said.

"WHY WOULD YOU DO THIS TO ME!? NGGGHHAAAH!" He screamed in pain.

"Oh, please!" Cadance rolled her eyes. "You did it to me." She turned her attention back to the magazine she was reading and crossed her white legs.

"I MEAN WHY DID YOU SWITCH US WHEN I WAS ASLEEP!?" He screamed.

"You said I was free to do so whenever I wanted to have a penis," she replied.

"I DIDN'T MEAN RIGHT BEFORE YOU WERE ABOUT TO GIVE BIRTH! ARRHGGGHH!"

"Another push, uh, um, sir!" the doctor said. Cadance leaned over to look between his pink legs.

"AAAGHHH!!" Shining cried out in agony. Cadance could see their daughter just beginning to appear, stretching the opening to an obscenely painful amount. Cadance sat back in her chair.

"Wow! That looks like it sucks! I am so glad I'm not doing it." She turned the page of the magazine. "You're doing great honey!"

Author's Note

"And that, Flurry Heart, is the story of how you were born," Shining said.

"Wow," Flurry said. "That was needlessly graphic."
