Three siblings working their first week in Luna's batguard discover an intruder on the grounds, and deal with said intruder in atypical fashion

Mostyn, Morsemere and Montague: Three siblings hailing from the Hollow Shades are in their first real week of work stationed for the protection of Canterlot Castle. Their talents make them a good fit for the position, even when pushing their superiors' patience to the limits.

This night, however, is unlike any other night. There's an intruder along the castle wall, and the trio are forced to deal with the situation. Little do they know, it's a scenario they were completely untrained to handle, and things swiftly take a turn for the lewd...

Meeting the Trio

“So is she fucking him?”

Morsemere craned his neck to look down the row, his dark amber eyes zeroing in on the boss slowly making her way towards him. The guard shift was just starting and Morsemere, Montague and Mostyn were starting their second night, their second real night, as they had all completed preliminary training and had passed. Morsemere was dying to know whether or not Midnight Blossom and Cloud Skipper were having sordid relations with each other. Relationships on the job were not approved by the Princess Luna and there was a really saucy rumor going around that Midnight Blossom was currently having relations with the Pegasus in charge, Cloud Skipper. Of course, there was no evidence to support that aside from said rumor and, of course, there is always a way to find out without boring actual physical evidence. His sister, Mostyn had an eye for that.

Four eyes. Two on her head, one on each flank.
“Listen, I'll ask when she comes down and I'll find out,” said Mostyn with a small smile on her face. She shook her mane back and forth, the blue/white hair swirling around her head. Adorning each of her flanks was a pale blue eye inset with an interrobang -her special talent made her a walking talking lie detector. Just by looking at a pony and studying their body language and their reaction she could tell whether or not they were telling the truth or telling a lie.

And everypony has reactions.

“Just don't get us into trouble, Mostyn. I don't need to be confined to a tower tonight,” grumbled Montague, eldest of the trio. Being the oldest of the three he often felt responsible for his two younger siblings, who would often shirk the rules and find themselves getting into more trouble than necessary. He was also the physically largest and strongest of the trio, and won more than his fair share at armwrestling.

Montague ran a claw through his dark green hair as Midnight Blossom approached. He could sense trouble was imminent. His sister was going to ask a very personal question to their superior and also because his brother was not in uniform again.

“Where is your uniform?” Midnight Blossom barked. Morsemere, who was just wearing the metal chestpiece, glanced down at himself in mock surprise

“I can’t find it, boss!” responded Morsemere, staring straight ahead past Midnights gaze.

“That’s ‘sir’ to you, newbie,” growled Midnight.

“Sir boss sir! Sorry sir! Surly won’t happen again boss, sir!” replied Morsemere, with a huge shit-eating grin on his face.

“Go to the barracks and get the rest of your uniform or you’re stuck in the gardens for the next week!” commanded Midnight, stamping her hoof. “GO!”

Morsemere split, flying out to the barracks as fast as his wings could carry him. Midnight rolled her eyes and groaned, watching the stallion pretending to careen into a stone column.

“Where’s Commander Cloud Skipper? Isn’t he usually the one in charge of inspection before designating us to our posts?” Mostyn inquired politely, with nothing but innocence in her eyes.

“Cloud Skipper is currently in a meeting with High Noon,” said Midnight bitterly. “As requested by him, I’m doing inspection and sending all of you to your proper posts. Now, this is only a temp-”

“Are ya fuckin’ him?” interrupted Mostyn.

Any idle chatter going about the line halted at the question. Nopony said another a word. Even the crickets seemed flabbergasted, their background chirping temporarily ceasing.

“What. Did. You just say to me?” Midnight Blossom stared daggers into Mostyns deep purple eyes.

“Are you fuckin’ him?” repeated Mostyn, with a toothy smile.

Midnight Blossom glared daggers at the mare. “Relationships amongst the ranks is strictly forbidden. No, I am not, and if I ever hear talk of that again, missy, I can guarantee something far worse than a write-up.”

“Duly noted, boss,” replied Mostyn, using a smug-as-possible tone of voice.

Midnight glanced back down the line with a piercing gaze, immediately quieting the hushed whispering that had broken out among the other stallions. The mare gave Montague a quick once-over, saw that he was completely satisfactory, and told him an incredibly disappointing place for him to stand watch the next eight hours.

“You’re on the east wall, far side. You’re going to be accompanying your siblings. Babysitting them. All night. And if you’re smart you’ll have enough time to straighten them the fuck out.”

“Sir!” Montague salute Midnight Blossom with typical gusto, the way a guard was supposed to.

“Any screw-ups that occur concerning them tonight, will be attributed to you. And any punishments or write-ups will fall on your wings,”
Midnight Blossom punctuated that with a jab at his chest. Mostyn whistled at that remark.

“Got it, Montague?

“Got it, sir!” Montague saluted, and Midnight Blossom marched down the line.

A second later, Morsemere flew in, and landed next to his brother and sister in full uniform.

“So is she fucking him?” Morsemere asked quickly, adjusting his helmet.

Mostyn snickered. “Ohhh yeeeah.”


“Could you two be less terrible? I shouldn’t have to babysit you both while at work. It’s bad enough I’ve been saddled with watching you guys a lot growing up,” Montague complained, trotting briskly back and forth between the two.

“Yeah but now they’re paying you to babysit us, Monty,” noted Mostyn, idly scratching her ear.

Morsemere laughed and sat on his haunches. “Mom and Dad never paid you for that? It’s about time you got some money due for keeping an eye out for us!”

“Well tonight, it’s MY ass on the line if you two do something and get punished, so really, I love you guys, but knock off on the shenanigans until tomorrow. I could go for an easy night of just, patrolling the third most boring part of the castle ground,” Montague sighed, taking a seat himself.

“Y’know it’s the most boring part of the wall that gets the most action from bad guys, right Monty?” quipped Mostyn, swishing her mane around and striking a battle pose. “We’re gonna kick some changeling tail tonight!”

“Missy, you are not getting into any fights while I’m standing by. I’ve seen bananas that bruise less than you,” Montague grinned hugely. “I thought it was funny that Midnight called you by the nickname we used to call you when we were little.”

“Dumb coincidence,” Mostyn stuck out her tongue.

When Morsmere was a little colt and Mostyn a little filly, her brother had trouble pronouncing her name. Instead of calling her Mostyn, he would just call her ‘missy’ until he was around six or seven years old. Montague had found the nickname adorable, and had persisted calling his sister ‘missy’ well into adulthood. Even Morsemere had recently picked it back up. Initially, she was bothered with it, but the nickname had grown on her.

“How come I don’t get a nickname?” whined Morsemere sarcastically.

“Monty and I have already decided that your name is too cool to replace with a nickname, Morsemere. It’s your eternal punishment,” Mostyn remarked, in an equally sarcastic tone.

“This current punishment kinda blows though. I don’t want to get Monty in trouble for something he didn’t do,” sighed Morsemere, jumping up and draping his forelegs over the wall. Being held accountable for stuff he didn’t do wasn’t his bag, and as fun as goofing around was, he didn’t want to get his big brother sacked. They all remained quiet for a moment, the situation weighing heavy on their minds. The mountainside wind whistled softly and then, it too died down.

“So Missy, I know you’re dying for me to ask how you knew for sure that Midnight is going at it with Cloud Skipper, so go ahead, tell me,” Montague finally said, wanting to lighten the mood.

“Ooh,” Mostyns eyes lit up, “So, I picked up on several tics. Blossom is not a good liar. When I asked, her left ear twitched slightly, she raised her right leg up a hair, as if she were physically recoiling. I saw her pupils dilate, eye twitch a little, her fur stood up a bit more, she caught her breath, and her tail flagged to the other side of her flanks,” finished Mostyn, her voice dripping with pride.

“Daaamn,” whispered Morsemere. “So, ninety-nine percent?”

“One-hundred ten percent that they’re rutting like first timers at the peak of heat,” Mostyn smirked, “and I bet if I pushed her I’d get even more tells but I got enough with just the accusation.”

“So… what’s that mean?” asked Morsemere.

“Means we’ve got some dirt on Midnight and Cloud Skipper until they either go public or get canned,” said Montague, matter-of-factly.

“No more of this punishment horsecrap that’s for sure,” Mostyn removed her helmet she was supposed to be wearing and set it on the ground, swishing her mane around happily. “Even without actual physical evidence, I know she’s lying. It’s what I’m good at.”

“Are you sure your cutie mark doesn’t mean YOU aren’t just an excellent liar?” Montague poked his sister in the side.

“Put a sock in it Monty, I know what I’m good at,” huffed Mostyn, flicking her tail at him.

“You’re good at getting into trouble,” teased Montague.

“Oh and you’re not! How many times do you get into trouble because you threw the first swing to start a fight!”

“That’s an early advantage in any fight!”

“Fight’s that you technically start!”

“If I don’t initiate I could get hurt!”

“You always DO get hurt, numbskull.”

“So? I always win my fights. You can’t even name any fights I’ve lost.”

“Maybe because you always start them so hard.”

“It’s the best way to fight! C’mon Missy, it’s on my flanks. I’m a bruiser. And, you’re kind of a bruise-ee.”

Mostyn scoffed. “That is not even a word.”

“Oh you know what I mean.”

“Guys,” said Morsemere quietly. Too quietly, as he went ignored in favor of sibling bickering.

“I am NOT that soft,” grumbled Mostyn, “Remember when I fought what’s-her-face, Night Watch, and won that fight?”

“Pleeeaaase,” Montague rolled his dark purple eyes, “you fought like mares. Poorly. I heard you were both crying from the pain afterwards.”

“WELL. I wasn’t!” snapped Mostyn. “I won that fight, Morsemere saw he was there.”

“You guys,” Morsemere said again, still peering over the wall.

“And I bet you didn’t throw the first swing either.”

“Well yea, I didn’t expect that to be a fight!”

“I didn’t expect you to win the fight either. In fact, who decided that? Morsemere? Because it sounds to me like you both lost.”

“Oh ha-ha, you weren’t even there you big-

“GUYS!”

The two siblings looked over at Morsemere, who was glad that he’d finally gotten their attention.

“What is it, Morsemere?” asked Montague, expecting some silly response in tandem with his sisters story.

He did not expect Morsemere to clear his throat, point over the wall and say: “There’s an earth pony mare down by the bushes, digging around or something.”

The other two siblings bolted over to the side of the wall and peered down, scanning around for the mare.

“I don’t see her, Morsemere,” hissed Mostyn, trying to be quiet. “Are you sure you saw a pony down there?”

“Sure as you are about spotting a lie,” said Morsemere, scaling the wall with full confidence. “It was definitely a mare, and she had a green coat.”

“Well, what are we waitin’ for then?” Montague clambered up on to the rock.”Let’s go investigate and find out what it is…” he glanced at his sister. “Hey Mostyn, if she’s a changeling scout and you out her as one again, you might not have to hold one over Midnight Blossom after all.”

“Luna willing,” she muttered, and followed her brothers down to the ground.

The Sweetest Night in May

View Online

Morsemere was the first to touch down, landing a few feet from the mare and stamping into the ground hard enough to scatter some pebbles. The mare made a startled little yelp and fell backwards.

"Halt! Who goes there!" Morsemere was putting on his tough guy voice. Despite not being as big as his brother, but could pull off intimidating when he actually tried. "State your business, occupation and your least favorite holiday!"

“That's uh. Oh! Howdy there! You startled me right there!" Replied the mare, looking away from Morsemere.

She appeared to be a rather unassuming earth pony -average height with light green coat and slightly reddish orange hair and main with light orange stripes. She had on a banana yellow bandana on the top of her head and was carrying two saddlebags around her waist which didn't seem to be carrying too many things. The little mare glanced up at Morsemere, her bright blue eyes quivering in fear.

“State your name along with some of those other things.”

“D-Daisy Mae!” she blurted out right away, “but all my friends call me Sweet Daisy Mae!”

“All your friends, huh?” Morsemere leered at her, spreading his wings out. “But what does your…. Granddaddy call you!”

“He uh… calls me Sprout?” Daisy Mae took a step back. “Why does that matter?”

“Just what are you doing out here then by these castle walls, huh?” Montague said from above, descending behind the much smaller pony with a powerful impact.

“Well I… uh, you see I was out here and I’m lost... no I have been lost and was sort of trying to track my way back to where I needed to be well I got distracted by that little ring of posies over there-”

“Would you perhaps say those posies are particularly pleasing pretty posies, perchance?” demanded Morsemere, eyeing the flowers suspiciously.

“Ugh, will you knock it off already? Come on. I don't want to be here all night interrogating a liar when I could just find out whether or not they're lying in the first place,” interrupted Mostyn, stepping up to the mare and, gazing right through her with her intense deep purple eyes, very simply asked of the little green mare one question.

“What does your cutie mark look like?”

Mostyn bore onto the slightly smaller mare, knowing that she would get an answer even if this mare didn't say anything in response at all.

Sweet Daisy Mae carefully studied Mostyn’s face and answered very carefully and assuredly, “It's a small bowl of salad with green leaves and small cherry tomatoes with a glass case of vinaigrette right beside it.”

Montague and Morsemere at their sister for instruction. Mostyn was silently studying the face of the little green mare.

“Monty, check her flanks,” she finally said.

Montague saddled up next to the the smaller pony and eyeballed her rump.

Sure enough on her flank was a cutie mark of a salad next to a class casing of vinaigrette just as described.

“S’what she says it is, Montague confirmed.”

"Okay, you check out, Mostyn smirked, pleased with herself. So, what are you doing out here, Daisy may? And don't lie to me. I’ll know.”

Daisy May inhaled deeply and shut her eyes. “I… came out here tonight, to, meet you.”

A pregnant pause from the whole group.

“What?” said Morsemere, breaking the momentary silence.

“To meet all of you,” said Daisy May quietly.

“Mhm, right, sure,” said Mostyn, a little less fazed by the answer than her brothers. “What else then?”

“Sorry?” Daisy May cocked her head.

“The whole reason you’re out here,” pressed Mostyn. “It’s on the tip of your tongue, but you’re withholding the truth. Spit it out, right now, or we toss you into a cell for trespassing when castle grounds are closed.”

Daisy May whinnied nervously, gulped and said. “I’m out here tonight… hoping to meet ponies like you… and… also, to uh…”

“Say it,” demanded Mostyn, stomping her hoof.

“For a roll in the hay,” said Daisy May, her eyes squeezed shut tightly.

Montagues jaw dropped. Morsemere whistled loudly and grinned hugely. Mostyn simply straightened herself and smiled proudly, having fished the truth out of another pony.

“I’m sorry! This is so embarrassing! I shouldn’t have done this,” Daisy May winced and bit her hoof. “This was dumb.”

“Definitely,” agreed Mostyn, with a wicked grin. “But you went through with it. And now you’re here with three of us at your disposal, ready and willing to make this the best night of your life.”

“Two.” coughed Montague.

“What? Really bro?” Morsemere looked at him in disbelief. “You’re gonna bail?”

Montague rolled his eyes. “I’d be for it if Missy didn’t put our jobs on the line earlier with that comment. I’m going to have to get back on the wall and keep watch in case Midnight checks up on us. I’ll also need to think up an excuse as to why you’re missing.”

Mostyn and Montague shared a glance, and bowed sagely.

“We’re not worthy to have you as a brother, Monty,” they said in unison.

“Knock it off,” he grinned, spreading his large leathery wings. “Try to be quick about it. You don’t have all night to fuck around down here.”

Montague flapped up back towards the castle wall, giving a wave with his wing once he was at post. Morsemere and Mostyn waved back, and then turned to the mare behind them.

“Now… just what are we going to do with you...” said Mostyn with a lecherous grin.

“Well,” Daisy May shimmied out of her saddlebags. “I was thinking we could-”

“Shush!” Mostyn shoved her hoof into Daisy Mays face. “It doesn’t matter what you think. What’s going to happen is you’ll be lying on your back while my brother fucks you silly and I sit on your face to muffle your screaming.”

“Why would I be screaming?” muffled Daisy through Mostyns hoof. In lieu of answering, Mostyn shoved the smaller earth pony to the ground. It was a light shove and the grass was soft, so Daisy May was unhurt. When she looked up and shook her head, she gasped softly.
Morsemere was fully undressed and glibly stroking his shaft with his hoof. It was huge; deep, jet black and throbbing in his grip, and hardening quickly. In no time at all it had plumped up to its full length and was sticking out a good few inches past his chest. A bead of pre-cum formed at the tip and dribbled onto the ground.

“Oh,” said Daisy May meekly, biting her lip. Mostyn flapped into the air and landed on top of the mare, standing over her.

“So, um… if you’re going to be sitting on my face… how will I breathin’?” she asked pointedly.

Mostyn lowered her head until she was face to face with Daisy May.

“You won’t be. You’ll be licking.”

With that, Mostyn took two steps forward and planted her plush, shapely rear right on top of Daisy Mays face.

“Mppf!” she muffled out into the warm wet mound planted on her snout. Her forelegs gripped Mostyns hips and felt the slightly larger mare begin to grind back and forth. Daisy May immediately began to lick at the entrance in front of her. Sure it wasn’t exactly the way she pictured this going, but it was what she wanted.

Morsemere walked over and positioned his big, throbbing dick at Daisy May’s entrance. She was small, but absolutely soaked down there. Even in the dim shaded moonlight he could see the wet patch of grass beneath her. Without much trouble he spread her hind legs and slipped the head of his cock inside. The mare spasmed and let out a muffled yelp. Morsemere couldn’t help but grin. This was going to be amazing. He slowly moved forwards, sliding inch after inch of his meat inside of her increasingly stuffed entrance until he could fit no more. Almost had the whole thing in there. The mare beneath him squealed in pleasure and clamped her legs up onto his body and held there as tightly as she could. Morsemere flapped his wings and draped both forelegs over his sister’s shoulders for support, resting his head forehead against the back of her neck for a moment. The heat on his loins, the tightness, the wetness -it was almost overwhelming. This mare wanted to be rutted bad.

And a rutting she’d get.

Morsemere raised his head, gripped his hooves tighter and began to piston his hips in earnest. The added weight on Mostyns shoulders pushed her pussy down even further onto Daisy Mays face and forced her snout even deeper into her pussy.

“Awww, yes,” Mostyn rolled her hips, grinding ever harder. Daisy May’s tongue was serviceable, licking and lapping feverishly all around inside her dripping pussy. Every-time she ground herself forward her clit bumped against Daisy’s nose and shot a bolt of pleasure up her spine. Quickly she rocked herself to a peak. All she needed was a little more, a little faster.

Mostyn felt a particularly strong jolt of pleasure rocket through her and paused herself, every one of her limbs shaking violently. With the rocking paused, Daisy couldn’t get her half breath of air from Mostyn going back and forth. She was being smothered by pussy! Desperate to breathe she writhed around and stuck her tongue as deep as she could inside. The roughness of her tongue licked against Mostyns clit.
“AAAAAAAAAHHHHHHHH!!” Mostyns wings snapped open and she arched her back, crying out as her first orgasm wracked her body, practically drowning Daisy May in hot, sweet bat-juices.

The sudden movement almost knocked Morsemere over. Almost. He kept his grip firm, continuing to plunge in and out of Daisy Mays tight little cunt. Every thrust in enveloped his big, throbbing cock with warm wet velvety tightness. She was so hot and tight inside. There were light trails of steam rising off his cock every time he pulled out. The lewd squelch of their juices and the light pat pat pat of his heavy balls slapping against her ass was music to his ears. What luck, running into a kinky little mare eager for sex in the dead of night. Morsemere adjusted his wings to reach down and lift her ass up in the air even higher. At this better angle he was able to fuck her even faster and harder. He could hear her muffled grunts with each subsequent thrust.

When his sister finished spasming from her orgasm he plunged himself deep inside Daisy May and held himself there, just to feel the warm rippling sensation of her tunnel massaging his cock, drawing spurts of pre out of the tip. He was so far inside he swore he could feel the tip kissing her womb. The thought of him blowing his load in there and filling this little mare with his virile seed made his cock throb with pleasure.

“Feelin’... good, sis?” breathed Morsemere into Mostyns ear.

“Yesssss,” she hissed, turning over her shoulder and licking his cheek. “So gooood.”

Mostyn hung her head and resumed her grinding, slower and lighter this time, trying to coax another orgasm. Morsemere snorted and went back to rutting Daisy May hard. He needed to cum. His dick was spitting pre and his loins were aching for release.

“MMMMFFFMF!” Daisy May felt her orgasm explode like a thousand fireworks going off inside her. She thrashed, kicked, and screamed at the top of her lungs, which thankfully, were muffled by Mostyns meaty flanks. Her screaming triggered a second, stronger orgasm ripping through Mostyn, and the batmare craned her neck backwards and howled out her own pleasure, another hot gush of juices spilling all over Daisy Mays face and soaking the fur on her neck too.

“Fuck it I’m gonna cum. I’m cummin! FUCK! Mostyn get off!”

Mostyn simply moaned and weakly flapped her wings, too enthralled to move. Morsemere’s cock throbbed hard, the head of cock starting to flare. If he didn’t pull out now it’d be wedged in her pussy. With a grunt he shoved his sister off to the side, reared up on his hind legs and pulled his twitching tool out of Daisy May with a juicy ,wet schlorrp.

The tip of his dick fattened and shot out a huge, thick jet of cum, streaking Daisy Mays coat from the inside of her inner thigh all the way up her forehead. The second stream was wilder than the first, sending a zig-zag of semen on her left hind leg, belly, and right foreleg. The third, fourth and fifth jets coated her chest and belly with fat ropes of his seed. The sixth and seventh were weaker, pooling on her stomach and jiggling like jello on a wobbly plate. The eight spurt came out in a weak gush and dribbled down onto her tail. A little bit of white dribbled down his shaft and that was it. Morsemere landed backwards on his ass and exhaled. His heart was pounding in his chest and he swore he was snorting steam.

“That was fucking… exhilarating,” Mostyn stood up on wobbly legs.

Wiped out from his own orgasm, Morsemere simply nodded and smiled hugely.

“Stars above,” she continued, shakily walking over to sit down next to her brother. They both had eyes on Sweet Daisy May. The mare was still on her back and panting. Her light green fur was matted all over her face and neck -her entire body was absolutely coated in pearly white spooge. It shone in the moonlight like glow in the dark putty. A dollop of it hanging from her snout fell and joined the pool of spunk on her chest.

“Fuck… Morsemere, we fucking ravaged this pony,” said Mostyn in awe, admiring their handiwork.

“I know… feels pretty amazing,” agree Morsemere, wiping his brow. They sat together for another few seconds collecting their senses when Daisy May stirred with a moan.

“Unn,” she picked her head up wearily, a happy, satisfied grin on her face. “That was the best rutting I’ve had in my life!”

Morsemere puffed out his chest proudly. “I get that a lot.”

Mostyn punched him in the shoulder.

“Oh sweet Celestia look at me!” Daisy May looked at the goopy mess all over her. “Why did you pull out?”

“What!?” Morsemere almost bit his tongue.

“Those flowers I pointed to you weren’t posies. They were, y’know the heart shaped flowers that act like a contraceptive. I’d been munching on them for an hour,” she explained, glancing over at the row of stalks behind her. “You didn’t notice that?”

“No,” Morsemere scrunched up his nose. He shot Mostyn a harrowing look.

“What?”

“You can tell she’s lying but you can’t tell she was eating the Cowwer Flowers?”

“She was pointing them out to YOU!” Mostyn thumped him in the chest.

“What, you couldn’t look at them for one second?”

“I was looking at her, Morsemere, it’s what I do. I don’t care about flowers. Do you see flowers on my flanks?”

“Excuse me… but uh,” Daisy May propped herself up to better look at the bickering siblings. “What now?”

Mostyn and Morsemere shared a glance.

“Well…” began Mostyn.

“Well our brother up there has been keeping an eye out for us this whole time…” said Morsemere with a glint in his eye.

“Not getting any action.”

“None whatsoever.

“If you’re satisfied though, you can get up and leave, we’ll get our uniforms back on and go back to our posts for the rest of the night, patrolling the castle wall and telling Monty all the details about all the hot, crazy sexual things we just did or-”

Morsemere grinned. “Or we go on post, keep an eye out, and he can come down here to rut your brains out.”

Mostyn shook her long, blue white mane and strapped her helmet back on. “So, what’s it gonna be, Sweet Daisy May?”

Laying on the ground, hair soggy from pussy juice and coat matted with sticky, cooling cum, the earth pony looked at the two ponies who just granted her wish of the wildest rutting of a lifetime and then up to the wall where no doubt, Montague was standing by at post.

Sweet Daisy May gave the pair a long look, and bit her lip.
