Your Duty

“Augh. It just had to come today.” Rainbow Dash whined, flying lazily beside Rarity and Applejack.

Rarity scoffed. “I may have been busy too, but a summons from the princess is hardly something to scoff at!”

Applejack shrugged. “‘Sides, it's not like it would take more than an hour.” She smirked, glancing over at a still annoyed Rainbow Dash. “Well maybe with you there it might take longer.”

“Hey!” Rainbow yelled. “What's that supposed to mean?”

“You know why were here, and we know how little experience you have with the opposite sex.” Applejack shot back.

“W-what!?” Rainbow sputtered. “I do too!”

“Your marefreind’s dildo does not count.” Rarity countered, drawing a giggle from the farm pony who shared a hoof bump with the fashionista.

The pegasus crossed her hooves and pouted, spending the rest of the way up to the castle in silence as Applejack and Rarity talked idly about their days and what they planned to do with the tax break that came with fulfilling their ‘civic duty’. Applejack had decided she was going to spend it on herself for a change and get a nice bottle of whiskey and one of them ‘fandangled bath bomb thingers that Big Mac always talks about’. Rarity had smartly decided to invest in her business but after some prodding she admitted she was going to get herself a nice bottle of chardonnay as a job well done present.

Rainbow Dash refused to offer her opinion on the matter, preferring to stew in silence the rest of the way there. Though she had secretly decided she would spend it all on girly clothes and sex toys, not like she would ever tell her friends that. If asked she'd probably say a statue of herself or something else she thought off the top of her head.

With some lively discussion, and vicious pouting, time passed quickly and the trio made their way quickly through Canterlot and up to the castle.

Once there they approached the guard at the gate, smiling at the dou of identical armored stallions that stood on either side of the golden portal. “Greetings and welcome to the castle. I assume you have your letters of invitation?”

The trio all nodded, handed over the letters they had received in the mail a week earlier. The stallion opened all three before nodding. “Perfect. Your all set, but before you go anywhere, princess Luna requested your presence as soon as possible. Would you be opposed to being teleported directly to her?”

The three exchanged a look with Applejack appearing the least convinced but even then, her sense of duty won out and she nodded reluctantly along with her friends. “Excellent. Sun Spear if you may.” The guard turned to his companion who lit his horn.

“Don't move please.” He asked.

The other three ponies all stood silently while the guard’s horn continued to build with power before it surged brightly, temporarily blinding the one pony who hadn't closed their eyes. Rainbow Dash stumbled around, spots clinging to her eyes as she blinked rapidly, trying to clear them.

“Oh hello princess, how are- oh my.” She heard Rarity mutter.

“Whoa nelly.” Applejack added.

The stumbling pegasus heard a strange grunt from somewhere nearby, followed by what sounded like Luna’s voice. “As you can see the last group didn't quite give it the attention it needed. Mmf, which I’m hoping you will remedy.”

Rainbow Dash toppled forward suddenly, her hooves getting tangled and sending her tumbling onto something soft, her lips landing against something warm and smooth and oddly salty. “Someone is eager.” Luna remarked, drawing a giggle from the other two mares.

The pegasus blinked rapidly, her vision finally clearing and allowing her to see that her muzzle was pressed against a dark wet pole of some kind. “What the.” She muttered.

It was the same color as princess Luna’s coat and was mottled with the color of her mane. After a second of confused staring, realization dawned on her and she nearly fell over backwards trying to put distance between herself and the titanic erection that had lay before her.

“Holy fuck!” she exclaimed before tripping over her own hooves once more and landing with a thump on the floor.

“Really Rainbow Dash? The first thing you do when you see a dick is scream and run away.” Rarity tsked and shook her head. “For shame. You received the same summons as the rest of us, you should have known what you were getting into.”

“No kidding RD, haven't you ever serviced a princess before?” The farm pony remarked, lifting an eyebrow. “Cus you act like you've never been summoned or something.”

“I haven't…” Rainbow Dash muttered, watching in awe as the two other ponies got straight to work.

The two more confident ponies slipped onto the bed on either side of princess Luna’s enormous erection. Rainbow Dash tried to say something but whatever she was about to say was caught in her throat as she realized just how truly titanic Luna’s cock really was.

It was almost as long as she was, and was as easily as thick as her hoof, probably even more so. Just from looking at it she figured it weighed at least several pounds, which would explain why Luna half sat there, with her back end firmly against the bed, while her forelegs propped her up and allowed the other two mares to get in close.

She was a little shocked at how easily her friends fell into their roles, maneuvering to the sides of Luna’s cock and beginning to apply a healthy layer of kisses and the occasional lick. Rainbow Dash however, was a little too stunned to react and merely stood there until Luna raised an eyebrow and gestured to her.

“Is your friend alright? I know we are large but our magic will ensure no one is- mmf -harmed.” Luna grunted.

Rarity shrugged, running her forehooves down the alicorn’s cock in concert with Applejack’s who mirrored the action on the other side of her. “She's a lesbian your highness. Though I’m pretty sure she still has bi on her identification card.”

The alicorn sighed. “That is most unfortunate as this is a three pony job.” She winced, her massive pulsing testicles growing even plumper. “I suppose we must seek out another third”

Applejack frowned. “Hold on a sec.” She glanced from the alicorn’s enlarged testicles then back to Rainbow Dash. “Come on RD, help us out here would ya? Did you even read the letter we received?”

The pegasus stammered uncomfortably. “I-I thought this whole thing was a joke.”

Rarity rolled her eyes, pulling back from the behemoth of a mare cock. “Come now Rainbow Dash, do you really think we would joke about something like this?”

Luna grunted, wincing slightly as her cock continued to twitch. “If you are unable to complete your duty please go outside and find my secretary. Subtle Script will just have to find someone to fill in.”

Rainbow Dash was tempted to leave, but found her eyes drawn down to the giant pole resting on the bed. Her gaze lingering over the mammoth erection as it pulsed with need. “W-well I could help, just this once.”

Luna sighed. “Oh thank the stars.” She pointed down to the end of her cock. “I’m going to need you to be on head duty.”

Rarity whined. “But princess I thought it was my turn.”

“Rares! You can't talk back to the princess.” Applejack scolded. “Sorry your majesty.”

“No no, that's completely fair, dear Applejack.” Luna remarked, nodding to Rainbow Dash. “But your friend has never partaken before and it seems only fitting that she get a turn before you get your second turn.”

Rarity frowned. “Fine, but next time it's mine.” The unicorn huffed and moved her head down the alicorn’s shaft, dragging her tongue as she did.

Applejack quickly mimicked the action, drawing a long moan from the alicorn, who winced suddenly as her cock continued to throb. “Please hurry up dear Rainbow Dash, I am in need of assistance.”

The pegasus shook her head, some primal part of her screaming out to do the right thing and be loyal. “Yes princess!” She said eagerly, diving into the bed and maneuvering her face near the enormous shaft.

Luna sighed contently. “Good, this will take all your strength so just remember, don't panic.”

“Wait what?” Rainbow Dash muttered, before she found her body tingling with magical energy. “Huh, this isn't so bad.”

A sudden feeling of tightness came from her midsection, spreading upwards towards her neck and finally up to her jaw. Thankfully it wasn't as bad as princess Luna had said it was, and after the spell had completed it just felt more odd than anything.

Rainbow Dash shrugged, silently wondering what that comment had been about if not the effects of her magic.

She glanced down as her friends continued to work away at the mammoth cock before her. The two mares were forced to use hooves and mouth at the same time due to it's sheer size. The pegasus shook her head and focusing on the princesses’, figuring she should get to work as well. After all she did have the most important task of all, which fit her just perfectly.

The mare leaned down, pressing her lips against the tip of Luna’s cock and running her tongue across it's hard length. The taste was strange at first, and Rainbow Dash couldn't quite put her hoof on it but after a few more licks she found herself transfixed by the bizarre taste. She couldn't describe it but it was amazing, delicious and strangely empowering. She caught herself thinking that it wouldn't be a bad thing if she was stuck here all day, just servicing this massive cock for hours on end.

Luna seemed to be enjoying it as well and the mares were treated to the sound of more than a few of the princesses’ moans of pleasure.

The minutes seemed to blend together, with Rainbow Dash’s world being consumed by an incredible need to service this perfect dick. She picked up speed, using her tongue and hooves in tandem in order to bring more pleasure to her princess, earning her a few grateful expressions from her fellow service mares and the princess herself.

Licks, kisses, and touching wasn't enough though, and Rainbow Dash soon founds her lips pressed against Luna’s shaft, doing her best to suck and slobber over the head. It was too large though and what little she did manage to get in her mouth was little more than an appetizer for her. The magic inside her seemed to recognize this and the pegasus felt an urge to open her lips as wide as possible and really try and take it all.

She felt her jaw creek, the muscles in her mouth shifting as if making room, and before she knew what was happening she felt her lips wrap around the head of Luna’s cock. It was a small change, but a noticeable one, the pegasus’ body having been altered in order to take a cock that should be much too large for it to normally handle. Her jaw had to be moved slightly, her teeth shifting just enough that they wouldn't get in the way.

With such a small change Rainbow Dash was able to fit her lips around it and begin to slide deeper, feeling that massive shaft occupy the entirety of her mouth. It was so massive and all consuming that it filled every last millimeter of space in the pegasus’ mouth, leaving no room for anything else, yet still she felt no panic for breath. Evidently the spell and the little air she was able to breathe through her nose was enough to keep her conscious.

With the massive cock residing inside her mouth the pegasus couldn't help but giggle hysterically, the strange joy of accomplishing such a task making her nearly see stars.

Rarity giggled, while Applejack just smirked, knowing the feeling quite well.

Luna smiled, a sense of relief washing over her as she felt at least a bit of her three foot erection getting stuffed inside someone. “Go deeper Rainbow Dash, you are going to need to reach the medial ring if you are going to reach your goal.”

The pegasus barely heard it, merely smiling dumbly and nodding as much as she could.

She pushed deeper, using her hooves to push herself down further on the cock, forced to crawl on all fours in an attempt to fit more of that enormous dick inside her. Inch after inch slid inside the mare’s body, forcing her jaw wider and wider until finally she felt that massive head slide into the back of her mouth and push deeper still. The way it stretched her throat was incredibly pleasurable and for a moment the pegasus almost felt as though her mouth and throat gave the same pleasure as if this beast of a dick was in her pussy. It wasn't enough to satisfy the mare and she crawled on, feeling the length slide further and further down her throat with each push she made.

Luna sighed contently, summoning up a floating board of magic to lean on while she let her service mares really get into it.

Applejack and Rarity had fallen into a rhythm, sliding further along Luna’s cock as Rainbow managed to cram more of it into her. Their hooves were a blur of movement as they did all they could to jack off the enormous length while they trailed kisses and licks across it.

Rainbow Dash stopped suddenly, noticing that she was nearly running out of throat for Luna’s massive appendage to occupy. She ran a hoof down her neck and lower still, feeling the enormous bulge Luna made. It still wasn't enough. She could see the mare’s medial ring several inches ahead of her, and with her goal in sight she felt a sudden need to feel her lips touch it.

The alicorn smiled down as she watched Rainbow Dash go deeper still, silently impressed that a ‘lesbian’ was this talented with a cock. She shrugged, who was she to judge? Though she did raise an eyebrow at just how manic the look in Rainbow’s eye was. In the end Luna shrugged it off, figuring the magic would keep her safe even if she went a little too far.

Rarity and Applejack picked up their pace, moving faster and faster, and giving the giant cock everything they had. Though Luna seemed calm, they could feel her length begin to twitch harder and harder with each passing second, signalling just how much she was enjoying herself.

Sure enough the alicorn moaned long and hard, making the mare’s all smile contently, Rainbow Dash most of all.

Who was by then, so close to her goal that her nose nearly touched it. She could feel the cock push into her stomach yet she knew she didn't have to worry about her stomach acid bothering Luna. The alicorn hardly even seemed to notice as her cock pushed deeper still, making a large bulge in the pegasus’ midsection, who merely grunted and shifting awkwardly on the bed.

She was close, as was Luna, and with each passing second Rarity and Applejack could feel their princess grow more and more heated. An odd gurgling noise drew their attention towards Luna’s now massive balls, sharing a brief concerned look before continuing their job with a renewed intensity. They weren't sure if Rainbow Dash could take it all, and they knew from experience that any further dawdling could have disastrous consequences.

“I'm close.” Luna anounced, her wings flaring.

Rainbow Dash grunted her affirmation, her hooves gripping the bed tighter as she dragged herself deeper still. So close! She thought, her nose brushing across the medial ring and making her shiver in pleasure. Just a little bit more!

“Here it comes! Be ready girls!” Luna called, her jaw clenched as her balls churning audibly.

Rarity and Applejack exchanged a look of panic and redoubled their efforts, doing everything they could to bring Luna to orgasm as quickly as equinely possible.

No I’m almost- there! Rainbow Dash felt her lips press against the mare’s medial ring, the bulge in her mid section having grown disturbingly large as her anatomy was forced to move in order to allow Luna’s cock the room it needed. But it was all worth it, she had reached the halfway point and-

A sudden surge of terror shot through the mare as she saw the cock ahead of her visibly bulge with seed. What the- oh no! Was all she could think before the first massive load ran down the cock, stretched her mouth and throat before finally exploding into her belly. It was enormous, easily larger than any single meal the pegasus had ever eaten, and it was quickly joined by another, and another.

She felt the princesses’ loads slosh inside her, making her gut distend and her belly grow large enough to appear pregnant with triplets. Yet still she had more to give, Luna’s cock continuing to twitch as load after load surged into Rainbow’s stomach.

A moment of panic nearly overwhelmed her, and the pegasus was met with the strange tightness returning. The next shot of cum that erupted into her belly didn't seem to have enough room and the mare felt as her intestines began to fill with seed. Three shots later and she felt cum shoot out of her, spilling all over the floor behind her. She tried to pull back, knowing that she had nothing else to give, and was relieved to feel Luna felt likewise, yanking her body off the alicorn’s cock and tossing her enormous cum filled body aside.

Applejack was there in an instant, clamping her lips around the tip and swallowing the monstrous jet of semen that shot out of Luna’s tip. Rainbow Dash watched in awe as the farm pony swallowed every last drop with such ease that the pegasus couldn't help but feel impressed. She continued to watch as the mare’s stomach grew larger and larger before it finally grew bigger then even her own.

Rarity was right beside her, and just as Applejack seemed unable to take even a drop more, the unicorn slipped in beside her, catching the next load in her mouth. And just like that the cycle continued again, until finally they all became little more then enormously bloated cum containers, appearing to be overfull condoms rather than ponies.

As the last jet of cum splashed into Rarity’s stomach, the unicorn sighed contently, patting her midsection that had somehow managed to become even larger than Applejack’s. The unicorn looked pregnant with quintuplets and ready to pop at any moment, her stomach hanging so low that it nearly brushed the ground.

Together the four ponies all sighed contently, resting on their sides while Luna smiled down upon them.

“Good work you three. Though there was some spillage.” Luna remarked, pointing down to the mound of spunk that was splattered across the floor.

Rainbow Dash grinned and shuffled her awkward weight over to the side of the bed. “Don't worry princess, I’m on it.”

The pegasus extended her wings, giving them a hard flap and enabling her to land on the ground, and plant her muzzle deep in the central mass of spilled sperm.

Rarity shot her equally as bloated friend a smirk. “Well?” She asked expectantly.

“I suppose you were right after all Rares.” The farm pony remarked, smiling down as the pegasus crawled all over the floor, licking up every drop of spilled seed. “She really is a cum slut.”

Luna smirked. “That she is.”
