The Reception Revelation

As Rainbow Dash gulped down another mug, Applejack was beginning to regret having apple cider at Sugar Belle's wedding reception. She knew how the pegasus could get. Loud, obnoxious, and a fire hazard. But worst of all, like the cider itself, she became unfiltered.

Big Macintosh and Sugar Belle took a break from the dancing patio. The new groom went to go carouse with the other married stallions for a bit to suffer their unsolicited advice or lamentations. Meanwhile, Sugar sat at the head table to give her hooves a rest. A very inebriated pegasus flopped down beside her in the groom's chair to chat up the blushing bride.

"So what's your relation to...?" Rainbow Dash asked, gesturing vaguely at the one table of ponies she didn't know.

"Oh, they're just some of the ponies from Starlight's town," Sugar said. "Except him," she pointed at a stallion. "He's my cousin."

"So where's his- uh... your aunt, er uncle?" Rainbow asked.

"Oh, his parents and I were never really close. He's actually a step-cousin from my father's first marriage. So he's actually... my dad's, ex-wife's, sister's son. So I guess he's like... an ex-step-cousin. We're more just friends than anything, really. He used to help out at my old bakery."

"What about the rest of your family?" Rainbow asked. "Your side of the aisle was mostly AJ's guests. So, what, are your folks racist against you marrying a mud pony? Or do they just not like you or something?"

"No, it's nothing like that," Sugar said. "I uh, I don't have much family at all. My parents died when I was younger."

"Hey! There you go! That's another thing you have in common with Mac!" Rainbow said with a goofy grin as she lifted her cider mug. "Cheers!"

Sugar smiled politely at the grossly inappropriate toast and tapped her champagne glass against the rim of the mug before Rainbow took another deep swig. This was not Sugar's first encounter with this version of Rainbow Dash. She knew not to take what she said personally. She was just being the 'Dash-hole' that AJ warned her about a long time ago.

"No sisters or brothers either?" Rainbow asked. Sugar shook her head. Rainbow nodded solemnly. "I know that feeling." Her serious expression vanished as quickly as it appeared. "But hey! Now you get a couple of sisters-in-law!"

Sugar's smile was genuine now. "Yes, and they've already made me feel like I'm part of the family. I feel so lucky!"

"I bet..." Rainbow grinned from behind her cider. "So speaking of getting lucky- I gotta ask- marrying Big Mac, how did you ever manage to get that past AJ?"

"I... I don't understand what you mean," Sugar said.

"Pssh!" Rainbow scoffed. "AJ's been in such a pissy mood ever since the engagement. What with Mac wanting to do the proper thing by you and be a faithful stallion. He must have broke her heart when he told her they weren't gonna be bumping uglies no more after he was married."

Sugar stared at her with her mouth agape.

"But like, while you two were dating, how did that work? Did you take turns, or- did you have like a schedule or something?" Rainbow took another gulp. "Don't tell me you do it at the same time- AJ never invites me for that! Ooh, have you tried a Prench Tower?"

"Wha-?"

"Oh! It's where one mare rides his dick, and the other sits on his face, and then when you both cum at the same time, you double hoof bump up top!" Rainbow Dash threw her hooves in the air. "Pow! Like the Prench Tower! Get it?"

Sugar Belle just stared at her in shock. Rainbow Dash stared back. The confusion on Sugar's face finally registered somewhere in Rainbow's addled brain.

"What? Don't tell me you don't... that he... He never told you about them?" Rainbow asked.

Sugar just shook her head.

Rainbow scratched her mane with her hoof. "Huh. I suppose AJ would have never told me either if I hadn't caught them in the act. Twice. But even when me and AJ started knocking tacos, she made it pretty clear she wasn't giving up what she had with him for me or nopony. Not that I wanted them to. Unf! Just thinking about them..."

Rainbow's wings sprang open and she fell out of the chair.

"Fucken... the ground is crooked over here!" Rainbow slurred as she climbed back to her hooves. She grabbed her mug with her hoof and finished off her drink. "Anyway, I'm gonna go grab a refill. Congrats on getting Mac all to yourself. I hope Applejack doesn't hate you forever." Rainbow closed one eye and squinted the other to try to focus on her orange marefriend talking with the other guests. "Nah, she wouldn't do that... Probably."

Rainbow staggered away towards the cider kegs.

Sugar Belle sat in her chair and just tried to absorb the information that had just been dumped on her. Rainbow was a serial prankster, but she knew her well enough now to know when she was fucking with her. She was clearly too hammered at the moment to be any kind of crafty.

Sugar caught the eye of her new husband. He smiled brightly at her and blew her a kiss. Sugar looked to the other side of the reception at the elder of her two new sisters-in-law. Applejack glanced over at her and gave her a small wave and a smile. Or what passed for a smile. The line of her mouth turned up a bit, but that was about it. She didn't smile with her eyes. It looked forced. Fake.

Sugar hadn't noticed it before, the change in Applejack's demeanor. She had dismissed it as stress in preparing for the wedding ever since the announcement. But now...

"Is everything alright?" Big Mac asked as he sat down next to Sugar, startling her slightly from her thoughts.

"What?"

"You looked worried," he said. "Sitting over here by yourself."

"Oh, no. My mind was just wandering. I'm fine," she said.

"Alright." Big Mac just smiled.

Living with Applejack must have made him unaccustomed to what lying looks like, Sugar thought. Mac was an honest pony. And she believed him when he made his vows of fidelity with her. Even so... It didn't preclude them from lying by omission. Still, he seemed happy enough. If they had sorted things out between them, then it wasn't her place to get-

"More champagne?" Applejack asked, standing in front of them with the bottle.

Big Mac nodded, but his happy expression fell. His smile was that same forced curve of his lips that his sister was wearing. That same bitter resentment of jealousy, and tension of things left unsaid.

And despite it being her own wedding, Sugar Belle suddenly felt very out of place.

Later that evening, as the last few guests departed the wedding reception, Apple Bloom helped her older sister with cleaning up. A thought occurred to her and she looked around frantically. "Where's Rainbow Dash? She didn't try to fly home did she?"

"She's laying down, inside," Applejack said.

"Is she on my bed? I swear, if she pukes in my bed again I'mma punch that mare in the box!"

"Apple Bloom! Language!" Applejack scolded her. "Also, don't you worry. I've got her sacked out on some hay bales in the barn to sleep it off 'till morning." Applebloom opened her mouth, but Applejack cut her off. "And yeah, I got her propped up on her side so she doesn't almost die again." Applebloom frowned. "I'mma get that mare to quit drinking!"

Apple Bloom just shook her head. "Lying doesn't suit you, AJ."

"Yeah, yeah... It's getting dark. Ain't you got a sleepover to git to?" Applejack asked. "Don't go making Sweetie and Miss Rarity wait up for you."

Apple Bloom tied off the last trash bag and added it to the others before she left.

Sugar Belle and Big Mac collected some folding chairs to put away.

"Now don't you two go troubling yourself with those," Applejack said. "Miss Rarity would have a fit if you went and got her dress muddied up! And Mac! Papa's ghost would haunt your ass if you go and bust a seam in his old suit!"

The newlyweds gave no argument to the contrary and disrobed, carefully folding their garments and putting them aside on a clean table before getting back to work.

Applejack huffed in aggravation. "Come on now. This is supposed to be your big day. You should be keeping your strength for your... wedding night," she muttered, not from modesty, but through her clenched jaw.

"Alright then," Sugar Belle said, "No more lifting." She tried her best to do things the earth pony way out of respect. But now she carried even more, effortlessly with her magic.

Applejack just threw her hooves in the air. "Fine! Do what you want! I can't stop you. B'sides! I got a sink full a dishes to tend to!" And she stormed into the house.

Applejack wasn't normally one to be quick to anger. But she dealt with it the best way she knew how.

With work.

Figures that hussy would take that away from me too! Applejack thought as she attacked the dirty dishes. First my brother, then that, what next!?

She scrubbed each plate with the wash cloth and stacked it in the drying rack. Then the drinking cups. When the rack got full, she toweled them dry and put them away. Then she refilled the sink basin with fresh hot water to start again. Her raw emotion was tempered with each methodical task. She scolded herself. Sugar is no hussy. I am. What Mac an I been doing behind her back? T'aint right, and t'aint fair to her.

Sugar Belle walked into the kitchen. Applejack watched her reflection in the window glass as she carried the folded table cloths to drop off in the wash room.

"I promise I won't wash them for you," Sugar Belle joked, trying to break the tension.

Applejack took a deep breath. "No, it's alright. I shouldn't have snapped at you like that. It's been a long day. I'm just tired is all."

Sugar smiled weakly at the back of Applejack's head. "Well, I'm sure that's true, but I'm also sure that it's not 'is all'."

"Can't say I know what you're getting at," Applejack said with genuine confusion.

"I know you can't say," Sugar said. "But I don't want there to be things left unsaid. Unresolved. Especially if we're going to be a family. I don't want to be a problem."

Applejack turned to look at her, "You ain't a problem! Who said that about you?"

"Nopony said that," Sugar Belle said quickly. "What I mean is, I don't want there to be a problem. I-" She shuffled her hooves anxiously. "I never wanted to make waves around here. That's why I try not to use my magic."

"I ain't mad about that neither! Your magic is a part of who you are!"

"I know. I just mean that- I didn't want marrying Mac to change anything around here."

Applejack opened her mouth to deny it on reflex, but paused. She felt her anger returning and she turned back around to keep working on the dishes. "Well... it can't be helped. It changes a lot. Changes plenty! But it's how it's s'posed to go, ain't it? Ain't nothing certain in life but change! Change in the weather, change in the seasons!"

Applejack dropped a soapy glass and it shattered on the floor. "FUCK!" Sugar Belle grabbed the dustpan and broom with her magic. Applejack grabbed them out of the air. "Don't be taking this too!"

"Applejack, I'm not trying to take away your brother!"

Applejack froze. "What are you-"

"I don't want what you have with each other to change!" Sugar said. "Your relationship, you don't have to stop!" The last shred of Applejack's poker face broke. "Yeah. That."

The kitchen door flew open. "I heard shouting," Big Mac said. "Is everything okay?"

Sugar Belle stopped him with her magic. "Just broke a glass," she said. "Mind your hooves. I'll have it swept up in a jiffy!" Applejack released her grip on the broom and dust pan and Sugar swept up all the broken glass, getting it into the trash can. "You finish up outside and we'll be there soon. Right Applejack?"

Applejack looked at Sugar, and then at Mac. "Yeah... In a jiffy," Applejack said through her teeth.

Big Mac looked back and forth between them. The tension was thick enough to float a block of lead. But he knew a hornet nest when he saw one. And he was wise enough to know not to poke it. "Alright..." He went back outside to finish cleaning up.

Once he was far enough away, Applejack asked, "He told you, I assume? I suppose I can't fault him for not keeping secrets from his spouse. Still, I don't care for him breaking a promise."

"He didn't!" Sugar said. "He keeps his promises, you know that!"

"Then how'd you catch wind?"

"I figured it out on my own."

Applejack narrowed her eyes. "You know I won't abide lying in this house."

"It's not important how I found out."

"Yeah, it KINDA IS!"

"I don't want to get her in trouble!"

"There's no way Apple Bloom could have- oh, DAMMIT RAINBOW! I'mma punch that mare in the box!"

Sugar Belle blocked the doorway. "AJ! AJ, wait! Look, this is what I was trying to avoid, okay? I don't want to be a problem, I don't want to get anypony in trouble, and I don't want anything to change! Look, I love Big Mac. Truly, I do. With all my heart. And... I can tell that you do, too. And, to be fair, you were here first."

"Hmff! Yeah."

"So... I'm willing to move past what happened while he and I were dating, and give you two my blessing going forward..." she trailed off.

Applejack raised an eyebrow. "I can tell from the tone of your voice there's a catch in there somewhere."

Sugar Belle blushed and shuffled her hooves nervously. "Well, it's a little embarrassing to say..."

"Speak for yourself. I just admitted that I've been getting porked by my own brother."

Sugar Belle bit her lip. "And I don't mind if you keep doing it if... if I get to watch."

"Come again?"

Almost, Sugar Belle thought as she rubbed her thighs together. "I was an only foal growing up so... I find it fascinating and I'm curious to see it. So... may I watch?"

Applejack pursed her lips.

"It doesn't have to be every time!" Sugar bargained. "Just, some times, at least?"

Applejack huffed. "I ain't got much of a leg to stand on, seeing as you got me over a barrel with this. You know I can't much object to your terms." Sugar Belle grinned. "I suppose the only thing stopping you is getting Big Mac on board. And I dunno how you plan on broaching the subject with him..."

The kitchen door opened and Big Mac walked in with his neatly-folded suit and her dress in his hoof. "The rest of the yard is cleared, so..." He looked at the two mares staring back at him. Sugar Belle had a grin that was usually reserved for foals opening Hearth's Warming gifts. She grabbed his hoof and looked him in the eyes.

"I wanna watch you fuck Applejack!"

Author's Note

The Honeymoon

"..."

"..."

"..."

The color drained from Big Macintosh's face.

"What!?"

"You heard me! I want to watch you fuck Applejack!" Sugar Belle repeated. "Upstairs! Now! In our bed!"

Big Mac looked at Applejack leaning against the sink counter as she rolled her eyes. "Yeah, she knows. Rainbow told her."

"Dammit Rainbow!" Mac cursed. "I'mma punch that mare in the box!"

"Take a number," Applejack muttered.

"It's not Rainbow's box I want you to be interested in right now," Sugar said. "It's Applejack's!"

He looked back and forth between them. "Is this really happening right now?"

"You ain't dreaming, if that's what you're asking," Applejack said. "But as far as if anything is gonna happen, well, that's on you at this point."

"Applejack already said yes!" Sugar said.

"I said that you needed to see how he feels about it first!" Applejack corrected. Big Mac looked at her. "I know you didn't want to be carrying on consort'n behind your wife's back. But yeah, if it means keeping things how they been for us, I'm fine with indulging her weird... curiosity. That is, if you are."

Big Macintosh looked back at his new wife, waiting expectantly for his answer.

"... Eeyup."

The floor fell out from under the Apple siblings' hooves as Sugar Belle lifted them both in her magic and quickly trotted upstairs to the master bedroom. She practically tossed Applejack onto the bed and placed Big Mac at the end of the mattress in front of her, before crouching down at the side next to them, looking back and forth between them.

"Okay, go ahead!"

Applejack gave her an incredulous look. "Well, you've kinda got us on the spot here. We don't usually have an audience."

"Oh, just pretend I'm not here!" Sugar said, making no effort to make herself less visible.

Between Granny Smith and Apple Bloom being in the house, it was always hard for Applejack and Big Mac to find time, or the opportunity to do this sort of thing, even before he started dating Sugar Belle. It wasn't like them to waste the chance. And yet, for the first time, Mac was finding himself with a bit of performance anxiety.

"You can't just expect us to, ya know, go for it," Applejack said. "I mean, if I knew we were gonna be doing this ahead of time, I'd be wetter than Seaquestria."

"Oh, well, yeah of course!" Sugar Belle said smacking herself in her forehead. "Well go on Mac! I know you like eating pussy!"

Big Mac somehow turned a darker shade of red. "Eeyup!" He knelt as the edge of the bed between Applejack's legs. He held each one in his hooves and parted them as he pulled her butt to the edge of the mattress, letting her tail hang down over the edge.

Sugar Belle looked over his shoulder. "Your pussy looks nice."

Applejack wasn't sure what to do with the awkward praise. "Uh, thanks?"

"Don't you think so, Mac?"

"Eeyup."

"Then you should say so!"

"I just did."

"No, I mean, you should say, out loud, in a complete sentence, that you think your sister has a nice pussy."

"Consarnit, Sugar!" Applejack cut in, "You ain't directing a goldarn porno here! You said you were just gonna watch and we should ignore you!"

"Right! Right, right!" Sugar made a zipping motion across her lips and moved back over to the side of the bed. "Carry on."

Big Mac looked at Applejack's pussy, and then at Sugar. "My sister does have a nice pussy."

"Land's sake..." Applejack groaned. "Mac, this is what I mean when I say that you talk too much. You got better things you could be doing with that mouth!"

Big Mac just smiled before leaning forward, taking a deep whiff of Applejack's heady aroma.

"Does your sister smell good?" Sugar asked.

"Sugar!" Applejack scolded.

"Sorry."

Big Mac leaned closer and ran his tongue up along Applejack's pussy in a wide swath before going back down again to make another pass, flicking her little nub at the top. He licked back down again before probing inwards.

"Does your sister taste good?" Sugar whispered.

"Whispering doesn't make it better!" Applejack said.

"I'm sorry, but I gotta know! Does she taste better than me? Or worse? Or do you like hers better because she's your sister?"

"Don't make him play favorites! That's unfair!"

Big Mac stopped just long enough to say, "It's different."

"Different like better? Worse? Sweeter? Sour? Bitte-"

Big Mac cut her off with an extra-wet kiss, getting his tongue involved as much as he could to share his sister's flavor with his new wife. When he broke the kiss she was physically taken aback, and finally speechless.

"Answer your question?" Mac asked rhetorically before returning to tend to his sister's pussy.

Applejack smirked at her. "So? What's the verdict?"

Sugar Belle considered herself more straight than not by most measures. But as her tongue licked her lips, she found that it was decidedly, "Not bad." By comparison, she had sampled herself in the past on Big Mac's dick. The stallions assessment was quite apt. Neither better or worse. "It's different." She looked at Big Mac between Applejack's legs. Most of his snout was buried in his sister's pussy, just under the blonde tuft of her pubic fur.

"Okay, yes, he obviously likes it." Sugar said. "And I know how good that long tongue feels up in there. But what about you? Your brother is eating your pussy right now! How does it feel with your brother's tongue deep inside your pussy?"

"What's not to like?" Applejack asked with a hint of annoyance.

"Is he better than Rainbow Dash?" she asked. Big Mac paused and waited for the answer.

"It's different," she said. Big Mac resumed his licking.

"Right. Right. Not playing favorites. But can he make you cum?"

"Yeah."

"Are you going to cum soon?"

"Geez, you know Sugar, it's kinda hard for me to get to that 'special place' with you playing Twenty Questions right next to me!"

"Right. Sorry. I'll leave you alone." Sugar slinked down to the other end of the bed to watch Big Mac work. Big Mac opened his eyes and looked at her. She looked back at him. "Sorry, I just usually never get to see this from this angle." She moved out of his sightline and looked at Applejack's pussy from behind him. "You should try focusing more on her clitoris-"

"Sugar! I know how to make my sister cum! Okay!? I don't need a coach! So please, PRETTY PLEASE, with ice cream on top, BE QUIET!"

Sugar Belle made a point of putting her hoof over her mouth and holding it there, more as a reminder for herself than anything.

With blissful silence at last, Big Mac could focus on what he was doing, and Applejack could finally lose herself to the feeling without distraction. She reached down with her hooves to grip his mane as he licked her in just the way he knew she liked. Her heels crossed behind his head to hold him against her more firmly as he licked and sucked her clit. She chewed her lip and her breathing became more erratic, coming in quick snorts through her nose. Her stifled moans were barely audible as her hips bucked against his face and he held her butt with his hooves to support her in perfect choreography until she bucked one last time. Her body went rigid and trembled as he held her. A gush of wetness dribbled down his cheeks and chin onto the hardwood floor. For a moment, the droplets were the only sound until her muscles gave out and she flopped back down on the bed.

He lifted his head from between her legs, his face dripping as though he had just gone bobbing for apples. And in a way, he had. He deftly climbed over her and kissed her passionately, their tongues twirling and dancing together as they wrapped each other in their hooves as consummate lovers.

Applejack's eyes were misty. "I thought I'd never get to have you again."

Big Mac's eyes glistened as well. "I'm sorry. I love you."

"I love you too." Applejack kissed him again. They hugged tighter and she buried her face into the nape of his neck. A moment later, she opened her eyes and remembered that Sugar was still there, sitting behind Big Mac with her hoof over her mouth.

"Aww, that was... You two are beautiful!" Sugar said. "Quieter than I expected. But still, I can tell you really love each other."

Applejack sighed. "Yeah, well, we never really had the luxury to be loud when making love."

"Well, now you don't have to be!" Sugar said. "I mean, I know Mac is usually pretty quiet anyway, and if you're gonna be the one with your mouth full next..."

"Is that a hint?" she asked.

"Well, you got yours. Just seems fair that he get his."

"Oh he's gonna get his!" Applejack said with a grin, getting up from the bed and moving Big Mac over to sit at the edge. She knelt down in front of him, eyeing up his sheath and balls. "Now what I like to do is go in slow like this..." she said as she gently nuzzled his scrotum with her nose, enjoying his musk.

"Or you could just..." Sugar Belle said as her horn glowed. A tendril of her magic pushed into his anus, making him squeak in a pitch usually reserved for batponies. She wiggled it around inside him and his shaft quickly sprouted up and out of his sheath, flopping onto Applejack's face.

"That's a neat trick," Applejack said with her brother's dick draped across her snout, before it rapidly stiffened upright. "Land's sake, Sugar! I ain't never seen him get that hard that fast! You're liable to make him pass out!" He was as hard as a tree trunk by the time Sugar's horn stopped glowing. Applejack scoffed. "Mac! I didn't think you liked butt stuff!"

The rugged stallion looked away. "I don't... not like it."

Applejack smirked. "You know, Dashie has a strap-on I could borrow if you want."

"Eenope!"

"Do you mean maaaybe?" Sugar asked. He snorted at her.

"He might just need some convincing, I reckon," Applejack said, leaning forward to nuzzle his scrotum again, and give attention to each of his kiwi-sized testicles, kissing, licking, and sucking each one into her mouth in turn.

Mac's dick towered over his sister's head, and twitched in time with his heartbeat. Though his wife had seen it plenty of times before, she still admired it. "I can see why you wouldn't want to give this up, AJ."

Applejack just hummed in agreement with one of his balls in her mouth. She released it to start slowly licking her way up his shaft, past his medial ring, before finally getting to the top. Her tongue moved around the ridge of his crown before gliding flat across his tip. She opened her mouth wide to take the tip inside and start sucking.

Sugar Belle leaned closer. "Okay, now this is the part I really want to see. I know my technique needs work, and I want to see how you can manage to deep-throat him."

Applejack pulled his tip out of her mouth and chuckled. "Sugar, have you seen this dick!? The only one gonna deep-throat this is a damn giraffe!"

"But Big Mac said it was possible!" Sugar said. "So I just figured... you-" They both looked at him.

"Mac! Did you tell her I could deep-throat you?" Applejack asked.

"Not you, obviously!"

"But somepony?"

"I only said that I didn't think it was for-sure impossible!" he said and looked at Sugar. "I didn't want you to stop trying."

"It's just a lot to take in," Sugar Belle said.

Applejack just rolled her eyes. "It's a lot for any mare," she said before she got back to sucking, and using her hoof to stroke what her mouth couldn't reach.

Sugar Belle shifted closer beside Applejack. "It's a lot for any... one mare." They both looked at her as she nudged beside Applejack and moved her hoof off his shaft. She leaned lower and started to lick and suck up along the side of his shaft where Applejack's hoof had been.

Applejack stopped and pushed Sugar Belle away. "Hey, now! I thought you were just gonna watch! And besides, I already licked it, so it's mine!" She started sucking his dick again.

"His dick isn't a cookie!" Sugar said, pulling it out of his sister's mouth. "And besides, he's my husband! Which means his dick is at least half mine!" Sugar started sucking his dick, herself.

"If'n that's so, then the other half is still mine!" Applejack said, muscling Sugar out of the way.

"What about me?" Big Mac asked. "Shouldn't it be thirds?"

They both glared at him. "NO!"

Big Mac just shook his head a watched the two mares fighting over who should be allowed to suck his dick. "Ladies, stop!" In the bedroom, the word 'Stop' was a powerful one. They both froze and looked at him in silence, Applejack, out of respect, and Sugar Belle with a mouthful of cock. Big Mac scolded them. "Taint right; you two fight'n like this! Applejack, Sugar Belle is your sister-in-law now. And we don't be quarrel'n with kin!" Applejack lowered her eyes in shame. "You've had this dick to your own self all this time. Sugar Belle has a lot of years to make up for!"

Sugar Belle took her mouth off his dick and narrowed her eyes. "Like... how many years are we talking here..?"

"And Sugar Belle!" Mac continued, "This is a rare opportunity for me an' AJ! You know you can have this any old time now! Why, you could drag me off to the bedroom in the middle of Hearth's Warming dinner and ain't nopony gonna bat an eyelash. Applejack can't do that!"

"Yeah!" Applejack said with a smug expression, sticking her tongue out at her. She pulled his dick away from her and got back to sucking.

"Now Applejack!" Mac chided, "What if Ma saw you right now!?" Applejack looked up at her brother with her mouth full of his dick. "She'd be a might disappointed that you forgot all her teachings on sharing! This ain't how she raised us! What would she say right now?"

Applejack took his dick out of her mouth and frowned. "She'd want me to share my brother's dick with my new sister."

Big Mac nodded. "That's right! There's plenty of 'Lil' Mac' for the both of ya. Now you two kiss and make out."

Sugar Belle raised an eyebrow. "Don't you mean, 'make up'?"

Big Mac's expression was stern. "I didn't stutter, Sugar Belle."

No stranger to kissing a mare, Applejack didn't hesitate. She held Sugar's face with her hooves and leaned over to kiss her. Sugar Belle was startled at first. She didn't accept the kiss right away, but she didn't deny it either. True to Mac's instructions, Applejack started to make out with her, getting her tongue involved. She paused briefly. "It don't count unless you kiss me back, Sugarcube."

Sugar Belle glanced up at her husband who just nodded in agreement, "Mm-hmm!" Applejack kissed her again with tongue. Sugar Belle closed her eyes and offered back her own. Applejack hummed in pleased confirmation, and got a bit more aggressive. Big Mac watched the sloppy make-up session for a minute or so before his hoof pressed his erection downward between their noses. They both opened their eyes and looked at each other across his veiny shaft.

He pushed it lower, breaking their kiss. "Now you two share."

The two mares kissed and licked up and down either side of his shaft. Sometimes they moved in opposite directions, taking turns to suck his tip. Sometimes they moved in unison, meeting at the end to suck and kiss his tip together, and each other.

"That's more like it," he said. "Now which one a y'all wants to open wide and finish this night off with a bang?"

Applejack looked at the other mare. "Well, I figured it'd be you since it's your wedding night. Consummate'n and all."

"No, Applejack, I said I wanted to see him fuck you, and I still do! We'll have plenty of time for consummating later."

"Fine. No objection here," Applejack said, climbing back up onto the bed as Big Mac moved off the side. She rolled over and spread her legs as Mac reared up.

"Wait, wait!" Sugar Belle said frantically as she climbed over Applejack. "I want to see it go in. Up close!" She looked back over her shoulder. "Oh, uh, I hope you don't mind, AJ."

Applejack looked up at her hips hovering over her face. "I ain't no stranger to having a gal's nethers straddling me. But what are you-" Applejack felt Sugar Belle's magic on her pussy. "Whoa, nelly!"

Mac looked at his wife's face hovering over his sister's pussy, spreading her lips open for him. "Sugar Belle, and here I thought you was straight as an arrow."

She smirked. "So is spaghetti until it gets wet."

"She ain't lying about that," Applejack said with the other mare's arousal dripping on her nose.

"Well go on then," Sugar beckoned to Mac. He stepped closer and reared up, holding Applejack's thighs with his hooves as he tried to aim himself. "Here, let me..." Sugar's magic helped aim him downward to his target. His dick was still plenty wet from their combined blowjob efforts. And Applejack was, true to her words, 'wetter than Seaquestria'. Even so, when Sugar Belle looked at his thickness and her snug entrance, she found it hard to believe that it would ever fit. She gasped as he closed the distance. "They're touching!" she squealed. He applied a bit more pressure and shifted his hips a bit to wiggle it slightly. Applejack's pussy bulged and stretched and after only a moment more, his tip popped through. "It's inside! You're inside your sister's vagina! Applejack! Your brother's penis is inside you!"

"I can tell," Applejack grunted. "We don't really need the play-by-play."

Big Mac leaned forward a bit and made a few small thrusts. With each forward motion, more and more of his length slipped inside. He shifted again and felt a sharp sting. He looked down at Sugar Belle's horn poking him in the belly. "Uh, Sugar, do you mind?"

"Oh, right." She moved off of Applejack and crouched down next to her side on the bed, laying her head on Applejack's lower belly, close enough for her blonde pubic fluff to tickle her nose as she kept watching. She felt the bulge inside Applejack's abdomen. Sugar sat up and watched as the bulge moved up into her belly. It didn't stop when Big Mac's medial ring reached her lips. With a little extra effort he pushed and Applejack gasped as it slipped inside. Sugar Belle gasped too as Big Mac kept going. At last his hips met his sister's. "Whoa... you can take the whole thing!?"

Applejack took a deep breath, getting used to the familiar feeling again. "Ee-Eeyup!"

"But it's so huge!"

"I'm well aware," Applejack panted.

Sugar Belle put her hoof on the bulge in Applejack's belly, "He's so deep! Feel this!" She grabbed Applejack's hoof and held it on the bulge.

"Trust me Sugarcube, I can feel it plenty!"

Sugar Belle was in awe. "Just- just how?"

"I suppose earth ponies are just built different," she said.

Sugar looked at Mac. "It must feel nice to be able to get it all the way in with her."

"Sugar-"

"You don't have to hold back and be so careful like with fragile little me."

"I don't mind being tender making love to ya," Mac assured her. "I love you!"

"I know, silly! I love you too!" Sugar said. "I'm not upset, or even jealous, really. It just- If anything, it's just reassuring to me that I made the right choice to not keep you from each other. You're a perfect fit for each other!"

"Mhmm," Applejack agreed, rubbing the bulge in her belly with her hoof. "I do appreciate that Sugar. I don't think I'd ever be able to find another stallion that could ever scratch this itch like he can." Big Mac leaned over and kissed Applejack. Their hips made little motions together. Not even thrusts as much as just little muscle flexes trying to push each other even closer together even as he stayed hilted inside her. "Stars above!" Applejack moaned.

"I've missed this," Big Mac whispered.

"You're one to talk," Applejack said. "At least you were getting some!"

Big Mac raised an eyebrow. "And Rainbow?"

Applejack smiled. "None of Dash's toys even come close to how good it is having the real thing back!"

Mac smiled and they kissed again, making more small motions together, and there was no sound other than Sugar Belle's excited panting. "Really now, you guys don't have to be quiet anymore."

Applejack just brushed her brother's cheek with her hoof. "I know you'd think we'd be all buck wild rolling in the hay, but we've never been one for a rodeo in the bedroom. Though I suppose we could get a little crazy to put on a show for her. What do ya say?"

Big Mac steadied himself back upright and gripped her thighs with a smile. "Eeyup!" He pulled back until his medial ring felt the cool air and pushed back inside again. He repeated the motion, slightly smaller, mostly staying inside her, as though dreading to leave her warm confines for the last time.

Sugar Belle stood behind him and wrapped her hooves around his broad chest as she whispered, "Don't worry, I promise this won't be the last time. You can have her as much as you want. With or without me. Apple Bloom is out of the house. Dash is passed out, and you know Granny can sleep through a hurricane! So I want to hear some mare-moaning, hoof-curling, ball-slapping fucking! Make her scream like I know you can!" Her magic pulled his hips back until only his tip was still inside and then she shoved him forward with a wet smack of their bodies colliding.

"Oof!" Applejack felt her breath get knocked out of her. Sugar grinned at Mac. He smiled back and started to make more big motions. Applejack brought her leg back and put her hoof against his chest. "Hey now, maybe I should be the one on top for this if we're gonna go nuts!"

Mac's enthusiasm faltered, but only for a moment before he backed off, pulling out with a wet 'plop'. He got back on the bed and Applejack climbed on top of him. "Beside, it's been a long day. Being your wedding and all, I oughta treat ya." She reached between her legs and guided his dick with her hoof as she squatted down onto it again. Sugar Belle was still in awe seeing Mac's entire length push up into his sister's body like that. Applejack sat on his lap to let herself get adjusted, not just her legs, but also internally. And then she started moving up and down on him again, slowly at first, and then bouncing with more gusto until her hat fell off.

"Yee haw?" Sugar Belle asked.

Applejack rolled her eyes. "Sure. Yee haw."

Sugar Belle's horn glowed and she prodded Mac butthole again, making his hip jump on reflex, getting a startled yelp out of Applejack. "Watch out, this bronco bucks."

Applejack's legs trembled and her hips came down with a sudden splash from between the two of them, dripping down his balls and darkening his red fur with dampness as she shivered. "Land's SAKE!" she cried out as she came. Her pussy quivered and gripped his dick.

"Nngh! AJ!" Big Mac's hoof tapped her thigh.

"Close already?" Applejack asked between panting. He nodded. "Alright, lemme just..." She stayed as still as she could before she started to stand up.

"Wait, where are you going!?" Sugar asked.

"Mac's close to going off, and I stopped taking my Moon Tea once y'all got engaged and we broke things off. And what with it being wedding season..." she put emphasis into the word. Sugar Belle put her hooves on Applejack's shoulders, pushing her back down. "What in tarnation are ya-"

"I want you to!" Sugar said. "I want him to finish. Inside you."

"Are you out your gourd!? I just said I ain't safe! Listen, next time I'll have my Moon Tea, and you can watch him cream my pie all you please, but-"

"You said you wanted a foal, didn't you?" Sugar asked.

"Rainbow said she wanted me to have a foal with her, and I told her I'd consider it. That is, getting a sperm donor." Sugar Belle pointed at Big Mac. "You know what I meant!"

"I want this," Sugar said. "I want this for you two. The way you kiss, the way you make love-" Sugar Belle smiled sweetly. It was so tragic that they had to hide their love for so long, and still would have to. "I'm sorry about before," she said. "When I said I wanted to see him fuck you. Because that's not what it is with you two at all, is it? It really is making love."

Big Mac had to agree. "Eeyup."

Sugar continued, "I'm sorry that you thought you would have to stop on my account. And I'm glad we talked it out. But I want you to have this. I want you to have his first foal."

Applejack and Big Mac exchanged a knowing glance.

"What?" Sugar asked. "Am I missing something?"

"Should we..?" Big Mac asked.

Applejack looked down at where her brother's penis was hilted inside her. "Well, I guess the biggest cat's already out of the bag..."

"What are you guys talking about?" Sugar asked.

"Our parents died nineteen years ago," Big Mac said.

"I know."

"And Apple Bloom's eighteen," Applejack added.

"I know that. We just had her party."

"..."

"..."

"Think about that for a minute," Applejack deadpanned.

"..."

"...oh, OH! Wait so does that mean-!?"

"Yeah, she's actually my daughter," Applejack said. "Our daughter."

"But- but how?"

"..."

"... Seems pretty obvious, don't it? Do I really need to explain the mechanics?"

"I don't mean that!"

Applejack shrugged. "What can I say? The short answer is we were young, dumb and horny. The long answer..." she felt Big Mac's dick twitching inside her, "... would take more time than we have right now."

Sugar Belle looked back and forth between them. "So... what do you say? Ready to give Apple Bloom a little brother or sister?"

Applejack chewed her lip. "What would we tell ponies? What would I tell Rainbow? You know I ain't comfortable with lying."

"Tell them the truth," Sugar Belle said. They both looked at her. "Tell them that you got a sperm donor."

Applejack looked down at the bulge in her belly. She rubbed it with her hooves and chuckled. "I suppose that'd be a fact." She looked at Big Mac. "Remember what Granny said after Bloom was born and I finally caught that whoop'n? She said I was only supposed to be having foals with somepony who would love me forever."

"Eeyup."

"Will you love me forever, Mac?" she asked as she started riding him again.

He put his hooves on her hips. "Eeyup!"

"Show me."

It took Big Mac all his focus not to go off right then and there. Even if it wasn't to be their last time, this was going to be a special night, and he wanted to make it last.

Applejack closed her eyes and focused on the feeling of him inside her. Fornicating now for the sole purpose of reproduction. It sent a rush of warmth through her whole body, but mostly in her loins. Her eyes fluttered and she looked over at Sugar Belle, watching them with her horn glowing. "What are you-"

"Hmm? Oh, just uh, playing with myself!" Sugar said, showing off an ethereal dildo with her magic. Big Mac felt the warmth of his sister's wetness running down over his balls. Either that, or it was the other half of Sugar's fertility spell.

"You don't need to play by your lonesome," Applejack said. "This ride's a two-seater."

"Eeyup!" Mac grinned and waved her over to straddle his face. She was happy to oblige and he wasted no time diving into her extremely excited marehood. It was the pussy of a baker mare that indulged herself in sweet treats. His sister's belonged to a mare who loved her apples. Equally sweet, in a different way. The plush butt on his face was squeezable soft from a diet of pastries. Applejacks rump was no smaller, but it was toned muscled sculpted from years of disciplined exercise and hard work. Not better or worse. Just different. Just like the mares they belonged to. He would have counted himself fortunate to have either as his mare that night. But to have both, he could think of nopony in Equestria more lucky.

"Oh, Mac!" both mares moaned in stereo above him. Sugar Belle's clit winking into his mouth and his hips bucked upwards to meet Applejack's. She lost her balance and slumped forward for Sugar to catch her. They embraced each other in a hug as Applejack whimpered into Sugar's shoulder, "Thank you for letting us have this!"

Sugar tried to respond, "I- I- Ah!" They just held each other's hooves as they both drenched the stallion under them with their shared climax.

"Ha! Prench Tower! Nice!" Rainbow Dash slurred, still black-out drunk as she staggered past the bedroom doorway, heading towards the bathroom.

Big Mac tried his best not to drown, feeling his own climax fast approaching. Enhanced from the spell, his dick throbbed harder, thicker, and longer than ever before. Applejack felt the pressure of his flared tip against her cervix with his last few thrusts. "Oh! My! GOSH!" she cried out as she and Sugar both looked at the bulge of his flare inside her. She felt light-headed and nearly fell backwards, but his steel-hard erection didn't yield, protruding harder from her belly. Sugar Belle could see his shaft started to throb and pulse. She touched it with her hoof, feeling him pumping load after load of his potent seed up, as deep as possible inside his sister. The weight of her body forced the entrance of her cervix to be pressed down squarely against the wide flare of his tip. Each powerful spurt of his semen was pumped straight into her uterus, flooding her womb to capacity. The bulge of his flare in her belly was eclipsed by her filling womb, looking like she had swallowed a whole grapefruit.

"Bah!" Big Mac gasped for air under Sugar, and nearly sent her toppling backwards off him as his hips bucked one last time on reflex, rocking Applejack forward again to flop onto his chest. The impact didn't help Mac catch his breath, but he caught her just the same. Her eyes flittered and looked into his.

"That was..." Applejack tried to say. "Something!"

"Eeyup," he agreed.

Applejack tried to move, making him wince. "I- I'm- it feels like you're stuck!"

Sugar sat up from the floor behind him. "That's the fertility spell I was saving for our wedding night!" she said. "It keeps him hard for up to four hours. And gives him an extra-wide flare to ensure no leaking. But it does mean-" Applejack tried and failed again to try to pull off of him. "It means you're gonna be there for a while."

Applejack wiggled her rump a little to get readjusted and she nuzzled against his chest to get comfy. "Suits me just fine. How about you, big fella?"

Big Mac had that big, goofy grin he always had after a romp in the bed. "Eeyup."

Applejack smiled and licked his nose, tasting Sugar Belle's pussy on him. "Hmm, I can see why you like hers..." She glanced over at Sugar Belle and patted the mattress for her to join them in the bed. Sugar Belle helped pull the blanket back and snuggled up next to her husband, still balls-deep inside his sister, draped over his chest.

Sugar touched her hoof against the round bump in Applejack's belly, imagining how she would look when she was ten months pregnant, with milk-filled teats. She imagined watching Big Mac suckling milk from his own sister. Maybe she would join in. The two of them suckling while they looked up at Applejack from under her round belly... before they would inevitably have to give them up.

"I can't wait to meet your little foal," she said.

"Our foal," Applejack said, as she draped her hoof over Sugar to embrace her together with Big Mac. "Ya know, if you think he's good at pleasing a mare... I ain't never got no complaints from Rainbow."

"Yeah, except your closet won't flush!" Rainbow Dash slurred, shuffling back down the hallway, wearing Sugar Belle's wedding dress, marred with a variety of stains.

"Dammit Rainbow!" Sugar Belle growled. "I'm gonna punch that mare in the box!"

Applejack just smiled and hugged her closer. She was already part of the family.
