A long time ago, Cadance felt incredibly guilty. She poked at the fruit before her with a magical fork. Only four hours prior, she was as happy as could be, skipping back to the castle after foalsitting Twilight Sparkle and finally satisfying her curiosities and desires. But the weight of the actual deed of… having an unconscious filly rut her butt for several moments and fill her rear passage with cum finally fell on her mind.

In essence, she raped Twilight and betrayed Shining Armor, neither of which knew of her actions. Her smile fading as the sick deed leaked from her tail hole as a constant reminder.

Celestia gave her niece a concerned look. “Cadance? Is everything alright?”

“Huh? Oh… yeah, it’s fine,” Cadance uttered, sighing as she continued to poke at her food.

Celestia frowned, never liking the idea of Cadance hiding things from her. “Cadance, did something happen when you were foalsitting?” She asked, moving to sit next to the pink alicorn, wrapping the smaller mare with a ivory wing. “You can tell me, I will understand and help you with your problems.”

Cadance felt herself snuggle into Celestia’s grasp. “Is it weird to want to be with two ponies at once?”

Celestia chuckled, her melodic tone calming the pink mare. “Six hundred years ago, I outlawed herds because they lost their purpose and the stallions became a bit more aggressive. The ponies of this age, Polyamory can be a choice but I feel that making it ‘look’ illegal will keep nobles like Blueblood from trying such things. As much as I love my nephew, the idea of him having a herd makes me feel ill.”

“So, it’s okay for me to love two ponies?” Cadance asked curiously.

“Does your heart have enough room for two ponies?” Celestia returned with a smirk. “So… who is the other special pony? Would it be Twilight?”

Cadance jumped at the mention. “I-uh… what makes you say that?”

“You went to foalsit Twilight for a few hours for her parents, it is either her, or her parents. A bit early to rob the cradle?” Celestia teased, laughing as Cadance began hoofing her side.

“It’s not like that!” Cadance grumbled, glaring at the white alicorn. She was happy that her aunt approved of not just her new crush on her protege but also the idea of Cadance loving her and Shining Armor. But there lay the problem, how would Shining Armor react to learning that Cadance having feeling for his younger sister, a yearning born of a curious night and a short talk with her aunt about polyamory. Shining never knew about this until far after his wedding to the Alicorn of Love.

“Nope,” Shining Armor stated, his face blushing light red as he tried to walk away from his wife.

“Oh come on, I did your fantasy of pretending I was Princess Celestia, while you rut me on the throne. Why can’t you let me have this?” Cadance cried, chasing after the white stallion.

“I’d agree to anything else, but I am not going to have sex with you and Twily. Like, I mean… seriously?” Shining uttered, feeling ready to gallop down the hallway, away from the crazy mare he called his wife.

“You two don’t have to touch… I want both of you to myself, am I not allowed to be greedy with sex partners? Just because I want Twilight to be with us in the bedroom doesn’t mean you have to push your penis into her,” Cadance argued, flying up to Shining’s face, cutting him off.

“While that is a major factor to why I don’t like this,” Shining uttered, rubbing his hooves uncomfortably. “My problem is… well, Twilight recently became an Alpha, right? Would she try to claim you? And after hearing about what she did to some stallion, would she do that to me?” Shining’s teeth jittered at the thought of his sister bending him over pressing her dick against his virgin taint.

Cadance put a comforting hoof on her husband’s shoulder. “I’ll make sure that if anypony is getting a dick shoved in them, it’s going to be me. It’ll be okay,” she reassured, caressing Shining’s face.

“But… Why Twilight? I could understand anyone else: Granite Hoof, Sparkling Gem, Lieutenant Sentry. Heck, I’d be okay with any of Twily’s friends if they were interested, but why Twily?” Shining asked.

Cadance grimaced as the memory of her night with a sleeping Twilight taking her anal virginity returned to her. “Well, Twilight was always adorable and she helped us before, right? And I feel like I still owe her for helping us with King Sombra and the Wedding, the latter you still owe her for.”

“I’ve already apologized for that, I don’t want to apologize again with my tailhole,” Shining grunted in annoyance.

“Then apologize with your wife,” Cadance cooed, kissing Shining’s horn. “Besides, I still owe her and I’ve been wanting this since I- we saw her rutting Chrysalis at your parent’s house on your birthday. Even you had to admit, she was pretty impressive for a mare half our size.”

“I don’t want to think about my sister rutting the monster that tried to ruin our wedding, no less the size of my sister’s cock,” Shining grumbled.

“What would help you warm up to the idea of sharing me with Twilight?” Cadance asked, holding Shining’s hooves with her own.

“Nothing comes to mind, actually,” Shining uttered, rubbing his chin as if putting some thought to it.

Cadance lets out a frustrated huff and flew to her room, leaving a surprised Shining in her wake. He turned to see Flash Sentry behind them. “How much of that did you hear?”

“Just about the entire thing, sir,” Flash uttered with a shocked expression. “So… your sister is technically your brother?”

“Another word about this and you’ll be patrolling the border,” Shining grunted, intimidating the younger guard.

Cadance was in the royal bedroom at this time. After letting her rage out. She had devised a new plan. She was going to force the encounter and make the two siblings talk it over between themselves and then try to coax them into being okay with rutting her. Nothing would stop her, this encounter will be perfect, a sexual experience she’s been dreaming of since she was young.

Twilight Velvet calmly drank her tea, happily letting the flavor dance on her tongue. “You have excellent taste, Rarity.”

Across from her, Rarity did all she could to keep her composure, her hooves occasionally clawing her white table. The source of her distraction was her Alpha, Twilight Sparkle, licking her pussy, suckling the winking clitoris and sliding along the pink walls. “Th- Thank you, Miss Velvet. You a-ARE too kind.”

Ever since Twilight returned from her trip with the Marezons, she had become more friendly, especially to her herdmares. When Chrysalis demanded love, Twilight didn’t bat an eye and happily helped the Changeling Queen, surprising everypony when the unicorn happily greeted them while crotch deep in the insect pony.

Everypony could agree that Twilight no longer treating sex like a chore or a scary idea was a good Twilight. Rarity felt this new change first hoof as she conversed, or attempted to converse, with her Alpha’s mother. The elder unicorn in the room chuckling as Rarity choked on her own words while her daughter happily ate the fashionista out.

“I must say, something special must have happened with the Marezons to make Twilight be this forward,” Velvet giggled, watching Rarity moaning against the table, her tail’s base brushing against Twilight’s horn and mane.

Twilight could feel her mare shiver against her muzzle and under her hooves. Her feminine musk wafting into her nostrils. Her tongue savoring the sweet taste of the ivory mare’s folds.

The door opened, Pinkie Pie rushing in with a scroll in her mane. “Twilight, you got a letter from Cadance!”

Before Twilight peeked up curiously, glancing forward to the needy look on Rarity’s face and souring. “Pinkie, could you read it aloud? I’m… a bit busy,” the scholar asked, returning to Rarity’s snatch.

Pinkie giggled at the sound of the sudden squeal that escaped Rarity’s lips and looked over the parchment. “Dear Twilight, I hope this letter finds you well. Your brother and I have been doing well in the Crystal Kingdom, standard marriage and monarchy stuff, you know? But I should get to the point of this letter.”

Velvet let out a chuckle and took a sip of her tea.

“I am writing to you to ask you a rather conflicting question, feel free to write back to say ‘no’ but it is something I’d like to explore at least once,” Pinkie read the rest of the letter in silence, her jaw dropping from the sudden question. “Twilight, Cadance wants to buck you with your brother!”

Twilight slipped on a hoof and pushed her snout into Rarity’s pussy, catching the fashionista by surprise. Velvet did all she could to keep from spraying tea all over the table, swallowing the dark liquid with an audible gulp. “I beg your pardon?” Velvet asked, coughing weakly.

After prying herself away from her ivory lover, Twilight conjured a purple rod and slowly pushed it into Rarity, making it grind against her velvet walls with firm strokes. Rarity gasping and moan on the table while her Alpha walked over to read the letter. “This is… I don’t know what to say…”

“How come? I figured you would say no on the grounds that your foalsitter wants a threesome with you and your brother,” Pinkie added with a curious look.

“Don’t get me wrong, I’ve had lewd thoughts about Cadance, but the idea of being intimate with Shining. If Cadance just wanted a one night stand with me, I’d be more inclined to say yes but… Shining will be there,” Twilight uttered, frowning at the idea of her being intimate with her brother. The thought nearly overpowered her will to keep herself from vomiting a little.

“Now why would Cadance just spring this on you right now?” Velvet uttered, rubbing her chin.

“I don’t know, a part of me wants to go… but I don’t want to do anything like this with my brother…” Twilight whine, shuddering as a cold chill ran up her spine.

“You don’t want your brother to poke you in the bum?” Pinkie asked with a straight face.

“Well, yes… but I honestly can’t see myself even mounting him like I did Thunderlane, the idea of me taking him anally… disturbs me, not as much as him taking me in any way but still,” Twilight added, putting the letter down as she began to think.

A harsh scream from the table tore the girls from the situation, watching Rarity’s arch her back in bliss from her orgasm, her pussy threatening to crush Twilight’s magic toy. As her climax petered out, she fell onto the table as an exhausted mess of a mare. “M-Maybe (pant), you should lay some ground rules between… you three?” Rarity suggested, her body a wash in the aftermath of her most recent sexual experience.

“Unless Shining is harbouring some fantasies involving Twilight,” Velvet added, the words made the younger Twilight feel sick. “I’m sorry Honey, it is a possibility after all, Cadance could have wrote that letter to hide a fantasy of your brother’s.”

“But… why?” Twilight groaned, her head falling into her hooves.

“I wouldn’t think of it in such a way but… after the last few weeks and your father’s fears coming to light. I’d say anything is possible,” Velvet added. “It’s up to you, dear.”

Twilight stayed silent for a moment, until a idea came to her. “Rarity, can I borrow some parchment?”

~dood~[/hr]

Cadance awaited for her sister-in-law’s response, pacing around the large study while Shining calmly read a book. The room itself was large and much like everything in the Crystal Kingdom, the walls were dark blue crystal with a fireplace, a large balcony opposite to it. The room made the two feel like it was a crystallized version of Princess Celestia’s study in Canterlot but brighter and less books.

“What could be taking her so long? I’m dying to know her answer,” Cadance thought aloud, ignoring the stares she got from her husband.

“Cadance… knowing Twilight, she’s probably panicking about this, trying to tell you 'no' in the most polite and bookish way possible, going through a tree’s worth of parchment,” Shining uttered, continuing to read his book.

A rolled up letter poofed into existence in front of Cadance, the pink alicorn quickly opening it and reading the letter to herself. “She said YES!”

Shining’s jaw dropped when he heard this, watching his wife skip and hop around the room in joy. “No… Twily, why?” The white stallion noticed that Cadance dropped the letter and began reading it himself, panic washing over him as he identified his sister’s writing and the the fact that she did agree to the threesome, but it continued on from there. “Cadance, there’s more.”

“What? what else did she say?” Cadance questioned, closing the distance between herself and her husband and looking over his shoulder.

“She’ll agree to this if me and her don’t ‘touch’ each other and focus our efforts on pleasing you specifically while you please us,” Shining finished, grunting in satisfaction. “Glad Twilight felt the same way.”

Cadance eyed the letter suspiciously. “Why would she include that?”

“Because it would be weird and creepy for two siblings to be fucking each other?” Shining answered in a flat tone.

“There has to be more to this,” Cadance uttered, now curious about ulterior motives. “We’ll ask her when she gets her for dinner this weekend.”

Shining watched his wife leave the room, dumbfounded that she now has it in her head that there might be something going on between himself and his sister. “This is what I get for marrying the Alicorn of Love,” he groaned, following the pink mare out.

~dood~[/hr]

The weekend arrived and Twilight found herself at the doorsteps of the Crystal palace, home to her brother and foalsitter. She would never have thought her reason for coming there alone was to have threesome with her sister in law and her brother.

Before her hoof could touch the glimmering door, it was thrown open and she found herself in the embrace of her foalsitter. “Twilight! Welcome! How are you! Oh I’m so happy that you agreed to this! Did you get taller?” Cadance said quickly. No sooner did she finish, she began dragging Twilight into the castle. “Come on, we’ll discuss this over dinner.”

If Twilight had any complaints, she had no time to voice them. She was dragged for several minutes until Cadance dropped her in the dining room, where her brother nervously ate. He turned and gave her a nervous smile. “Hey… Twily.”

“Hi… Shiny,” Twilight greeted nervously.

Cadance noticed that both ponies were a nervous wreck and then a thought occured. “Why are you two nervous? Have you two been hiding anything from each other?” she asked with a teasing grin.

Both unicorns turned to her slowly, the straightest look on their faces with a tinge of blush. “Are you still under the impression that I have a secret fantasy about my little sister?”

“Wait, what?” Twilight asked, a bit astonished that her fear would actually come to life.

“After your letter explaining the boundaries, Cadance now thinks that you secretly loved me, and with my protests about this whole thing made her think that I loved you,” Shining explained with a bitter sigh.

“Oh, so you were against this as well? I thought I was the only one,” Twilight chuckled, wiping her forehead.

“Twilight, what do you mean?” Cadance asked in a worried tone.

Twilight noticed the sad look she got from her old foalsitter and sighed. “I… almost didn’t agree to this because of Shining’s presence in this. Mostly because I didn’t want us to hurt what we have now, we’re siblings and friends. Not only that, he’s married to you. Also, I’m not a terribly huge fan of being penetrated, I’d rather be the one penetrating and I… also don’t want to sodomize Shining, it would be…”

“Weird?” Shining finished for her. “I felt the same way, heck… I didn’t want any part of this until you sent that letter explaining what your conditions were. Man, you are cute, but… the idea of us having sex just…. makes me uncomfortable.”

The two siblings smiled and instinctively hugged. “Glad you understand,” Twilight said, holding her brother tightly.

After a second both ponies broke away, chuckling awkwardly. Cadance had a strange frown on her face, her lips puckered and raised slightly as she stared at her two favorite ponies. “So why did you agree to this at all, Twilight?” she asked.

“Well, about a week ago, I probably would have sent you a letter saying ‘No’ and a list of reasons why I wouldn’t want to be intimate with you and Shining. But something happened a while ago and… let’s just say I’m a bit more ‘open’ than I once was and I won’t lie. I always did have a crush on you Cadance. The idea of having sex with you before finding out you two were dating or getting married was… a desire of mine,” Twilight explained, her face bright red, trying to use her mane to hide her eyes.

“Aww… did you fantasize about me” Cadance teased, nuzzling the nervous purple mare. The gesture making Twilight jump a bit.

Shining chuckled as Twilight squirmed away from the affectionate Princess. The scholar righting herself, fighting off her blush. “I-well, yes. But to be fair-”

“Yeah, yeah… you had fantasies about Celestia, everyone does,” Cadance added, shooting a teasing look to her husband.

“I-I suppose,” Twilight uttered, she shook her head, banishing lewd thoughts as a new question came to mind. “Why me? I’m sure you two made some friends here. Heck, Shiny brought his right hoof stallion with him, maybe he could be of better service than me.”

“Because I didn’t want Flash Sentry. As nice as he is, he won’t be able scratch the itch I had for a long time,” Cadance cooed, softly walking to Twilight, a swagger in her step as she smiled at the purple mare.

“And that itch requires me?” Twilight uttered, swallowing her breath as Cadance embraced her with fore hooves and wings.

“This itch… requires both you and your brother. My biggest sexual fantasy, Twily, is getting mounted by you and your brother at the same time,” Cadance said with a loving tone.

“Is this about the thing back at our parent’ house when everypony caught me having sex with Chrysalis? Because I can assure you… my penis isn’t that big normally, that was a spell,” Twilight explained with a blush.

Both mares ignored the sigh of relief from Shining as Cadance brushed Twilight’s mane with a hoof. “It doesn’t matter, Twilight. I’d still get the thrill of getting drilled by both of you, regardless of your penis size. I just want you and your brother to have fun with me.”

Twilight presented a straight face, absorbing all that Cadance had told her. “Is it strange that you are rather… aloof about Shining and I having sex with you.”

“Not as strange as your extra few inches of height,” Cadance teased, poking Twilight’s nose.

“I got enough of that back home, especially when Rainbow Dash said if I grew any more, she’d actively rename me ‘Magic Mac’ because I was one of the biggest and a desirable mate,” Twilight grimaced, hoping to rid herself of the teasing Rainbow, Pinkie, and Gilda gave her. “Though, it is neat to be the same size as Gilda.”

“I bet she appreciates it,” Cadance giggled, holding Twilight closer.

“Yeah, yeah, but me and Twilight still need a game plan for you,” Shining added with a chuckle.

Twilight nodded and gave the pink alicorn a meek smile and scooted away, just as the waitress began putting out more food.

After dinner, Cadance told the two that she was going to ‘freshen up’ and asked the siblings to meet her in the royal bedroom.

“Okay… what’s the plan?” Twilight asked curiously.

“I was thinking… You pretty did half of Equestria so, maybe you can eat Cadance out while she sucks me off, just to get things ready,” Shining suggested.

“And what about me? I don’t mind eating mares out but… you two are getting pleasure, not me,” Twilight grumbled.

“I know, I know. But after everything is ready, we switch Cady around and I take her pussy while you take her head.”

“Okay… and then I take her ass and we double penetrate her?”

“If I don’t cum, if I do… then we’ll switch her around, I get her to clean me while you do her butt. That way, we don’t have to touch and Cadance is getting it in two ways and since we’ll be using the same holes, no sloppy seconds or cross-dicking,” Shining said happily.

Twilight nodded with a smirk. “That could work, but what if Cadance doesn’t want that?”

“Cadance loses her mind during sex, she’ll be too busy drooling over both of us to care,” Shining laughed, leading Twilight to the bedroom. “I’m serious about the drool thing, Cadance has a bad case of sex face when she’s into it.”

Twilight nodded, soon finding herself in front of the bedroom. They both took a deep breath. “Remember, no crossing lances and we don’t mount anything that’s purple or white, only pink and has a heart cutie mark.

Shining nodded in agreement as he pushed the door open. Both ponies were assaulted by the thick aroma of lavender and jasmine, the smell so thick that everything else almost because non-existent. Scented candles and incense burned a fair distance away from the bed and a top it was Cadance, her eyes following Shining and Twilight as they entered, licking her lips as she did. Her coat was shinier than before, her mane tied back, her royal regalia was replaced by stockings, a slight hint of eye shadow with ruby red lipstick. “Took your sweet time, trying to figure out how you two were going to do me?”

“That’s right, Cady. It’ll be a night you’ll never forget,” Shining smirked, walking purposely towards his wife. Twilight cautiously approaching from another angle where Cadance’s hind legs were.

“Adorable, because you’re half right,” Cadance grinned, using her magic to pull two chairs from their spots at the side of the room and had them collect Twilight and Shining, forcing them to sit down. While this happened, Cadance slid off the bed with satisfaction in her eyes as her favorite ponies were now on each side of her head, their dick slowly growing from their crotches. She giggled as she noticed that Twilight didn’t have the sheath or testicles that Shining had and decided to taste her LSILBFF first. “Not bad, Twily. Not as big as your night with Chrysalis, but I can definitely work with this.”

Twilight shivered as Cadance’s firm hoof rubbed her growing purple member, the alicorn of love staring at her dick while the other free hoof stroked her brother.

“What about me, honey?” Shining winced, his wife’s grip was impressive for a hoof, quickly stroking it up to its peak size.

“Sorry, Shiny. I need to entertain my guest, you’ll get off, I promise,” Cadance cooed, bringing Twilight’s shaft to her lips and teasing it’s flat head with her tongue. She looked up and her heart fluttered to see Twilight squirm and whimper adorably.

There was little to describe the sensations of Cadance’s mouth as the pink princess began to take her shaft into her mouth. Cadance’s tongue was beyond amazing, the gentle yet firm glides of the slippery appendage across her bulging veins. Her foalsitter was definitely proving her status as ‘Princess of Love’ simply by oral, the purple rod was hard within the minute of Cadance stroking it.

Slipping away, admiring the saliva polished head of her sister-in-law’s cock, she turned to her husband, giving him the same treatment. She purred around her lover’s cock as a hoof began petting her, softly thrusting his shaft into her mouth.

“Cadance, shouldn’t… we be pleasing you, this is your fantasy after all,” Twilight whimpered, shivering in her seat from the pink mare’s hoof.

“Can’t blame a girl for giving you two a taste test,” Cadance cooed, blowing softly onto the grey shaft presented to her. She switched back to Twilight and did the same before capturing its head with her mouth, suckling it softly, teasing the scholar immensely with her tongue and vibrating mouth. With an audible ‘pop’, she licked her lips and looked up to the purple mare. “I want you both to be ready to take me hard, I want you both to fuck like you would fuck Chrysalis after a bad day,” she ordered, turning back to Shining to moan around his shaft.

Giving each other nervous looks, both siblings huffed and groaned form Cadance’s oral skills, switching between the two but keeping a hoof on both of them, gently stroking them and letting her saliva and pre-cum to rub against her soft coat.

She gave both dicks a glance, satisfied with how much saliva glistened off them and stood up, wagging her tail and teasing both ponies more as she walked to the bed. “Come on, rut me good.”

Twilight and Shining quickly shot out of their chairs and took a side. Twilight giving Cadance’s slit a long lick before pressing her tongue against the impressively clean taint before her. Shining pulled Cadance closer to him, their lips pressed against each other, their tongues dancing between their teeth, raising his mare onto his lap, all the while his sister prepared the Princess’ rear entrance.

Cadance shuddered, the feeling of Shining’s cock filling her, stretching her small pussy around his generous girth always made her squirm with delight. The glorious feeling was amplified by Twilight’s tongue at her ass, getting her tight star ready for something much bigger than a unicorn’s tongue. Simply bouncing on her husband’s lap, feeling his cock slide and pull on her insides made her purr like a kitten, she was almost worried about Twilight spearing her rectum, making her absolutely smashed on the sensations of pleasure.

“Goodness Cady,” Shining chuckled, holding his wife’s flanks as he pumped into her. “Did you just get a whole lot tighter? We barely started.”

Cady giggled when she felt Twilight position for her ass, her heavy purple cock threatening to enter her. “It’s about to get a lot tighter, Shiny,” she cooed, biting her bottom lip in anticipation.

It was a bit difficult, but Cadance wasn’t the tightest ass Twilight has ever mated with. She could feel the clenching sphincter resist her approach but it ultimately opened to allow the first bit of Twilight’s penis inside, making both mares moan from the union. Twilight continued to push, the tight ring clenching her dick hard, squeezing her with a vice-like grip.

Shining suppressed a yelp as he felt Cadance’s tunnel became much more compact. Between the narrow wall of flesh, he could feel his sister’s rod throbbing next to his, her heat adding to Cadance’s feminine oven causing his rod to grow. Sure enough, he could feel his wife drooling as she moaned and begged for more.

The moment Twilight’s shaft entered her, stirring up her insides with her brother, Cadance saw stars. The feeling of having the dicks of her two favorite ponies filling her, giving her warmth and pleasure, was indescribable. Shining’s hooves wrapped around her barrel, holding her still. Twilight kneading her flanks while pounding the Princess deep. Cadance’s head laid next to Shining’s, mindlessly drooling from the dual pleasure.

"H-How are you holding up, Twily?” Shining asked, gritting his teeth from the intense squeezing his lust-bound wife was doing.

“She’s… making it hard to move,” Twilight moaned, tightening her grip on her ex-foalsitter’s ass. “I think I might be too big for her.”

That sentence snapped Cadance out of her revelry. She swallowed the buildup of saliva and wiped her mouth of the remainder before glaring at Twilight. “Keep fucking me, by the end of the night… your dick will be molded to fit my ass, missy.”

Twilight swallowed her breath and continued to hammer away at the pink rump before her. The multi-hued tail brushing against her chin and front every so often. Her squeak-like grunts drowned out by Cadance’s moans.

Shining’s eyes shot open in a shocked expression, he knew when Cadance was close but she was far closer than he thought. The constant strings of ‘fuck me’ and ‘fuckin’ yes’ and the rare ‘fill me’ in a whimpering tone as she forced herself backwards into Twilight while he thrusted upward. “Cadance? Are you about to cum?” he asked, almost teasingly.

Cadance’s lips tightened as she nodded, her body shaking with every thrust made into her and the constant pleasure she received.

“Did- did we break the Princess of Love?” Twilight questioned in awe, tightening her grip and pounding the pink alicorn harder.

“Oh fuck, yes!” Cadance screamed, unintentionally answering the scholar’s question. A loud screech signaling her climax.

If the two ponies weren’t shook up and stunned by the sudden royal voice of the youngest princess, then the her pussy and ass becoming vice-like and attempting to milk them roughly did. Shining and Twilight stood no chance, letting out twin grunts and moans as they began filling Cadance’s holes.

Shining was bigger than Twilight by a somewhat noticeable margin. Twilight’s cum volume was much larger than his. While Cadance could feel the strong hearty blasts against her womb, she felt her rectum drown in her sister-in-law’s seed, only serving to reawaken her fire within her.

However, Shining could still feel his little sister filling his wife, a few minutes after he had finished spending his sperm, he glanced down to see a very slight gut in his wife’s belly before Twilight finally pulled out, accidentally getting a the last of her seed fire onto Cadance’s back and wings. “That’s a… how are all your marefriends not pregnant, constantly?”

“Magic,” Twilight panted with a blushing smile. She quickly located her chair and sat down, watching her cock deflate slightly.

Cadance pulled herself off of her husband’s dick and laid next to him, admiring the fatter belly the purple mare gave her. “Wow… I forgot that you explode like that.”

Lazily, both Shining and Twilight noticed the red flag that Cadance’s statement raised. “Forgot?”

Cadance froze, yelling at herself for letting that slip as both siblings sat up with confused looks on their faces. “What do you mean by ‘forgot’? This is the first time you and Twilight had sex… right?” Shining asked.

“It should be, I’d definitely remember mating with Cadance,” Twilight put a hoof on her chin. “Unless…”

“Unless?” Shining repeated, a bit worried.

“Uh… a ridiculous thing to note: I’ve been… prone to become a very aggressive lover and just, do EVERYTHING recently, starting to hope this actually didn’t happen,” Twilight added, swallowing her breath. “My herd can attest to me being aggressive and then not remembering what happened.”

Cadance couldn’t believe what she heard. While it was horrible to find out that Twilight has random bouts of rough mating and then forget it ever happened but this was so perfect for her to use as an excuse for her to play off the question. “T-That’s right. I was foalsitting you and you came down with a wide smile on your face. Before I knew it, you had your penis in my butt and your rutted me for… a few minutes before cumming inside me, then you passed out.”

Shining’s jaw dropped while Twilight grimaced, looking down to the floor. “That… certainly does sound like what could have happened. I- I’m so sorry, Cadance.”

Cadance smiled and pulled Twilight into a tight hug. “It’s okay, my ladybug. It happened a long time ago.”

“Wait, what? I- we’re just going to forgot that my little sister raped my wife years ago?”Shining questioned, trying to wrack his brain around the strange logic happening before him.

“Why? And punish your sister for something that happened when she was fourteen and kickstarted this fantasy?” Cadance asked, giving Shining a teasing look. “As your Princess and wife, I’m giving Twilight a pardon for doing something not within her control, she even has an alibi, her herd as mentioned that this has happened, so that should be proof enough.”

Shining frowned; while he didn’t want to punish his own sister, the idea of letting somepony that raped his wife years ago getting pardoned didn’t sit right with him. “This is ridiculous.”

“I… don’t agree with this as well, but considering what I’ve had to put up with, I’m already decided to just nod and smile,” Twilight commented, sharing her brother’s irritation to the situation.

“Don’t worry, I’m here for you, Twily,” Cadance cooed, petting the purple mare. “And the night is still young.”

Twilight blushed hard, smiling weakly. “Should I be worried that I’ve heard worst reasons to have sex?”

“Yes, yes you should,” Shining replied, arching a brow when Cadance blew raspberries at him. He blushed when his wife’s tail brushed against his penis, spurring its growth.

Twilight let a faint whimper slip from her lips when Cadance’s hooves touched her member, stroking it back to life.

With a quick spin, Cadance presented her rear for Shining while eyeing Twilight’s member, giving the purple rod a few licks. With Twilight wincing from her seat, watching Cadance’s tongue glide across her cock. Shining watched Cadance shake her rear in front of him, his own proud member filling with blood. With a groan, he slid forward and grasped his wife’s flanks, angling to re-enter her cum-packed snatch.

Cadance let a smirk cross her face as her lips pressed into Twilight’s penis, slowly making her way to the tip to take it into her mouth. The head of Shining’s cock rubbing against her labia before penetrating her. With her backside full of stallion meat, the alicorn of love tied her mane back with magic before forcing her head down onto Twilight’s crotch, softly fucking her head on the purple mating stick.

Twilight was gifted with the sight of Cadance bobbing her head over the scholar’s penis, her body shaking back and forth with Shining’s thrusts. The purring and moans that vibrated around the purple cock enraptured Twilight in their stimulating grasp, her eyes locked to her ex- foalsitter’s, the two mares finding it rather thrilling to watch the other give or receive pleasure, from Twilight’s quivers and moans to Cadance’s suckling noises and muffled groans.

Cadance eagerly stuffed her face full of her sister-in-law’s cock while her rump was getting pounded by her husband’s thick member. She soon felt Twilight’s hoof on her head, pushing her down to take more of the long purple shaft. While Twilight was no longer the small filly she could have deep throated easily, she was also smaller than Shining, making the act itself rather easy to do. Her joyful giggling reverberated onto Twilight’s member, making the purple unicorn squirm from the sensations.

Unbeknownst to the girls, Shining was beginning to take interest in the scene before him. The sight of Cadance lightly gagging around Twilight’s member was rather arousing, making his dick harder inside the alicorn’s depths. While he was still a bit uncomfortable with sharing his wife, he couldn’t deny that the view of exciting.

“I- I didn’t realize that Cady had such a mouth. I’m- ohhh- actually kinda jealousss of you, Shiny,’ Twilight moaned, holding Cadance’s head in place to start rutting the Alicorn’s throat.

Shining chuckled, slamming his body into his wife as hard and fast as possible. “Can’t go wrong with the Princess of Love, Twily. A great lover, my best friend, the most beautiful princess, and the best fuck ever.”

Cadance hummed proudly around Twilight, staying firm despite the rough treatment her mouth got from the lilac mare’s hips.

“I… can only think of- Sweet harmony, your throat is tight. The closest I can think of is… Pinkie and Chrysalis,” Twilight panted, her need to cum growing.

“Bet Cady blows both of them out of the water,” Shining chuckled. Feeling his wife spite him in thought, he slapped her flanks with a firm hoof.

“I-sure… yeah, Cadance has the best mouth,” Twilight replied, biting her lower lip in anticipation.

Cadance sensed Twilight’s hesitation to answer and push the mare off with her magic. “Which one of them is better than me?” she demanded, surprising both ponies.

“P-Pinkie, Chrysalis… is a bit sloppy and tends to scratch my penis with her teeth,” Twilight answered, defending herself with a magic shield.

“Are you saying that my mouth is better than the changeling that tried to ruin our wedding?” Cadance continued. The sudden outburst caused her and her husband to forget that the two were physically connected still.

“You… do have better oral and anal skills, yes?” Twilight answered again.

Cadance looked into her charge’s eyes for a moment and smiled. “Nailed it! I’m better than that buggy bitch!” Her celebration was cut short when Shining slammed his hips forward, bringing her back to reality.

Twilight let out a giggle and returned to her position, only this time she stood while making the Alicorn of Love perform fellatio on her. While her hard-on somewhat diminished in the short time it spent outside of Cadance’s luxurious mouth, she was quickly taken forward, close to the point of orgasm.

The panting and groans from Shining Armor alerting Cadance that her husband was close to finishing inside her. She used her magic to pull both members out just in time to stroke them off, forcing Twilight and Shining to coat Cadance in their sperm, Most of Twilight’s coating her front and face while Shining’s load coated her wings, mane and back.

Cadance licked her lips, tasting both the sperm from the siblings on her tongue and lips. “Now that… was fun, but I think I got one more round in me.”

Shining grimaced as felt tired. “I dunno, I think-” He was pushed back by his wife, her proud, cum drenched form towering over him.

“You won’t have to do anything, I’m going to ride you until that last of your creamy goodness is milked from your big hard cock,” Cadance growled seductively, forcing herself onto Shining’s shaft. She turned back to Twilight. “Come on and fuck me.”

With little hesitation, Twilight climbed onto Cadance’s back and repositioned for the pink mare’s used anus. But a shift of magic caused her cock to aim for the already occupied hole.

Believing that she’d slip right in, Twilight thrusted forward. A howl of delight escaping Cadance’s lips while both Twilight and Shining were shocked to feel the other’s dick sliding next to each other. “Cadance! We agreed that this won’t happen!” Twilight stammered, failing to pull out.

“Sweet fucking Celestia, I’m so full, so hot…” Cadance shrieked, softly rocking her hips along both cocks, causing them to rub each other inside her overstretched marehood.

“Cadance!” Shining shouted, wincing from the tight squeeze within his wife’s pussy. “I- I can’t… pull out. Darn it, Cadance!”

“Don’t pull out, just keep going… it feels so good,” Cadance moaned, a weak drop of drool dripping onto Shining’s coat.

Twilight’s cock slowly pulled away, grinding against pink walls and a thick white dick. Magic pushing her forward roughly, making Cadance’s studs groan from the pleasure while Cadance continued to be a drooling, screaming mess of a alicorn.

After some coercing, Twilight placed her hooves on her ex-foalsitter’s rump and slowly began moving, feeling her cock slide against her brother’s as he moved with her.

With Cadance’s pussy clamping down around them and the friction of them grinding against each other, the siblings couldn’t help but moan, their bodies wanting more of Cadance’s hole, regardless of the other occupant.

Twilight began rutting at a normal pace, slamming her hips into the alicorn’s rump while Shining thrusted upward. Her favorite ponies unintentionally working together to bring Cadance to another screaming orgasm.

The Princess’ vice-like snatch clamping down hard on the invading members, her lovers grunting their satisfaction and moaning from the constant grinding and fucking. Cadance’s eyes fogged over, unable to see past the haze of her own lust. She felt too good to care, only wanting her mates to fuck her harder and faster.

A moment slipped by them, all three ponies drenched in sweat, though Shining was drenched in saliva and feminine juices, thanks to Cadance’s drooling and constant string of orgasms. The alicorn could no longer scream her delight to the heavens, her voice was too weak to announce her joy.

Despite her prior experience, Twilight couldn’t keep herself going, her body was weakening drastically while her cock throbbed proudly next to her brother’s. She pushed herself in one last time, filling Cadance’s womb with thick spurts of seed, easily replacing what leaked out of her rear. Shining followed her example, helping his sister in expanding his wife’s womb with his cum.

Cadance’s eyes sparkled like stars, getting filled by both ponies triggered her strongest and most exciting orgasm yet, moaning her approval, her body milking both cocks of their hot and juicy cum.

Unable to keep herself standing, Twilight fell onto Cadance’s back, sleep taking her as she felt the last of her essence surge into the pink Princess. Cadance fell onto the side, forcing Twilight to lie behind her, gazing into her knight’s eyes s she relished in the warm feeling inside her. “That was amazing, honey.”

Shining weakly nodded, panting as he looked deep into his wife’s eyes. “Yeah… it was, it was strangely great.”

“Twilight, how was it?” Cadance asked, turning to see Twilight snoring softly, cuddling up to her back side, her cock slipping out of the alicorn’s cooch and leaking cum onto the bed. “I’ll ask her tomorrow, that was exhausting.”

“I won’t deny that,” Shining yawned, pulling Cadance into a hug. “Love you, Cady.”

“Love you too, Shiny,” Cadance cooed, snuggling into her stallion’s body. a faint smile gracing her lips when she felt Twilight hold onto her her back. “Love you, my little ladybug.”

~dood~[/hr]

The sun was at it’s highest when Cadance was the first to rise. Her body reminding her of what she went through the previous night, coated with the cum of her husband and sister-in-law, their fluids sloshing in her belly and womb, making her glad that she used a contraceptive spell before partaking in said actions.

She noticed that both her mates last night clung to her fore limbs, holding her tightly. She giggled at the sight and used her magic to squirm free, only to watch as Shining and Twilight clung together like magnets. She decided to take this time to get clean, not wanting to approach the day covered in sperm and love juices.

The moment the shower came to life, Shining began to stir. His smile brightened when he saw the silhouette of his wife with blurred eyes. “Morning Cady, he cooed, kissing his partner on her forehead.

“Morning Shiny!” Cadance called out sneaking out of the bathroom to watch the drama unfold.

Hearing Cadance behind him caused some panic, his eyes readjusting to see the sleeping form of his sister grasping his body. “Uhh…” the captain uttered, trying to wish his situation away.

“Morning BSILBFF,” Twilight moaned, kissing Shining on the chin. The act making him shiver in horror.

“Morning Twilight,” Cadance called out. She giggled when Twilight snapped awake, staring at the spot she just kissed. Her eyes scanned up to her brother’s shocked expression.

It took less than a second for both siblings to spring away, apologizing for making the other feel uncomfortable. All the while, Cadance was laughing in the bathroom.

Both siblings glanced at each other before glaring at the bathroom door. “Not. Funny.”

Cadance would disagree, giggling to herself as she cleansed her body.

After all three ponies cleaned themselves, Shining and Twilight shooting disapproving glances at the giggling Princess. “Are you still laughing about me and Twilight cuddling?” Shining questioned with a annoyed tone.

“Kind of,” Cadance chuckled. “Your expressions were just..., priceless.”

Twilight grumbled, irritated by her ex-foalsitter’s childishness. “Let’s just… go eat breakfast, visit for a little bit, then I can go home to my herd.”

“Aww, you don’t like me anymore, Twily?” Cadance cooed, giving the younger mare sad puppy eyes.

“No, no, it’s not like that-” Twilight grimaced, unable to find the words.

“She’s teasing, Twilight. Don’t let her win,” Shining commented, marching forward.

“Are you seriously that upset? You didn’t even kissed each other on the lips,” Cadance added, rolling her eyes.

They reached the dining room, Twilight and Shining sitting across from each other while Cadance sat next to Shining, a crystal waitress bringing out a large tray of fruit for the three ponies.

As they ate, Cadance was trying to win her favorite ponies back. Twilight, however recalled an event that she felt Shining should know, something that might hurt badly. “Shining?”

“Yeah?” Shining asked, glancing up to his sister. Cadance giving Twilight a curious look.

Twilight thought carefully about what she should say, but ultimately sighed. “So, Mom spent a few weeks at my place, to give Dad some time to himself after he had a meltdown about… Mom’s past.”

“Okay, can I ask what past is that?” Shining said, taking a sip of the coffee that was brought to him.

Another waitress placed a cup of coffee to Twilight, the purple mare giving the blue crystal mare a happy thanks. She turned back and took a gulp of the scalding nectar. “Remember when Mom went to the bar in Ponyville and worried Dad? Especially when everyone learned that she had sex with a lesbian couple and myself?” Shining nodded.

“Your Mom fucked everything before she married your Dad, Shining,” Cadance finished, causing Twilight to choke on her coffee, Shining performing a spit take to the floor.

“Cadance!” Shining shouted with a deep blush.

“It’s true, she actually had sex with me while we dated and made your dad watch,” Cadance explained, she noticed the look of fear on his face. “No, she didn’t make him rut me, she did… made him cum on me, but his penis didn’t touch me at all.”

“Eww…” Shining uttered, shuffling in his spot.

“And… during Mating Season, I had sex with Mom,” Twilight uttered, preparing for her brother’s outburst.

“Oh, if it was during Mating Season, in Ponyville of all places. I’m sure Mom just… had no choice? You were the closest penis probably,” Shining reasoned, shrugging.

Twilight and Cadance stared at the white stallion in disbelief, until the scholar cleared her throat. “Also, my herd made Mom curious and we had sex a few days before Mating Season.”

“Twilight!” Shining shouted, shrinking in his seat in disgust. “Uggh… why? Does Dad know?”

Twilight tapped the table with her hooves nervously. “I’m kinda hoping Mom would tell Dad when she goes back. Considering she sent a small herd of mares to sleep with him for the duration of her vacation from him.”

“Mom sent her friends to sleep with Dad?” Shining uttered, lying back in complete shock of what he had heard.

“If you want, I can go round up some of my old friends and have them mate with you for a week while I visit Twilight,” Cadance cooed, rubbing her husband’s side.

“Please don’t,” the siblings said in unison. “It was… awkward to be around Mom, especially after I mated with her, four times.”

“FOUR TIMES!?” Shining screamed, staring at Twilight.

“Three of those times were during Mating Season, and she just… made me mate with her all of those times,” Twilight stated, her hooves up to protect herself.

Shining let out a relieved sigh. “I suppose if it’s during Mating Season, without the barrier… I’m sure even Mom would be all ‘stallion crazy’ there. Glad I wasn’t there.”

“So it’s okay for your Mom to have sex with Twilight, so long as it’s during Mating Season?” Cadance asked, in disbelief.

“Cadance… have you ever been to Ponyville during Mating Season?” Shining asked, sighing when his wife shook her head. “I was stationed there once to help stallions escape the night before, a few years before Twilight moved there.”

Cadance and Twilight glanced to each other worriedly, as Shining continued. “We lost half our troop for a week. They came back to us changed, some announcing to be gay the moment they got back, their lower bodies put in a cast. I didn’t get to see any of that but everypony that was taken by the mares and didn’t claim to be gay… avoid all mares for a month, avoiding eye contact with everything that was female.”

“I… didn’t think it was that bad, sure I got cuddly with you and Twilight but, really?” Cadance uttered, she began thinking about the ramifications.

“You are not allowed to visit me when Mating Season is about to happen or while it’s happening,” Twilight stated with a stern tone, causing Cadance to whistle innocently.

Velvet let out a sigh, returning from her stay at Twilight’s library to her home in Canterlot. “It feels like it’s been forever.”

She walked up to the door and opened it, chuckling as the smell of sex filled the room. She didn’t take to account the sudden hugs she got from her mares. “Twilight!” Velvet flinched a bit when her mares, Quick Silver, Blue Blaze, Bright Light, and Squeaky Clean all tackled her, nuzzling her body. “We missed you!”

Behind them was Bronze Hoof and Night Light, chuckling at the scene. “Need some help, honey?” Night asked.

The mares helped Velvet up, who slipped past them and pulled Night Light into a deep kiss. “I missed you honey, sorry I wasn’t here for Mating Season… things happened.”

Night Light let out a sigh. “I know, and I appreciate you sending your friends to stay with me but there is a reason why I married you.”

“And did this make you remember why I married you, dear?” Velvet asked, looking deep into her husband’s eyes.

“It kinda did,” Night Light blushed. “You- All of you really didn’t have to do this.”

“But I did, because I didn’t want you to feel inadequate to what I’ve done before,” Velvet cooed, nuzzling the dark blue stallion.

“I’m sorry I got all… subconscious about your black book, I’ve always knew about your life before us but, I was still in denial about it,” Night uttered, pulling Velvet into a deep hug.

Velvet’s smile faded, pushing her husband away. “I’m sorry, Nighty. I- I need to add some more names to the book.”

Night Light only smiled and nodded. “Go ahead, Velvet. I won’t be mad.”

Velvet’s smile returned, she leaned up and kissed her stallion’s cheek and walked to their bedroom, where she kept her book.

Everypony crowded around Velvet as they watched her enter the names of every pony Velvet mated with at Ponyville: Octavia Melody, Fluttershy, Queen Chrysalis, Gilda, Zecora, Pinkie Pie, Cup Cake, Twilight Sparkle.

Night Light fainted on the spot, upon seeing the his wife write their daughter’s name.

The mares gasped at the sight of the name, until Bright Lights asked. “Was she any good.”

“No touching her,” Velvet scolded. “And yes, seven out of ten, would consider banging again.”

Author's Note

Shigiya looked at this, dood.

I finally got to chapter 24, dood! It fell behind because of my prejudices towards Shining Armor being in the same room as Twilight during sex so I apologize for that, dood.

Next on the agenda: Horcecocked, the continuation to the first One-Shot chapter of the Trash bin fic (where Twilight watched Applejack and Fluttershy fuck than eventually fucks Pinkie after Rainbow teases her about it, dood), Chapter 6 of my Borderlands fic: New-U, and the next chapter... I'mma call it 'Honesty', dood.

Now to go to work, have a sore throat from drinking and walking around in a hoodie, and play Hunie Pop because I hate myself, dood.
