As quietly as he could, Shining slipped into Cadance’s suite in Canterlot Castle. Even though the guards outside were trustworthy, he didn’t know who else might be paying attention, so he was careful to shut the door slowly and hold the latch so he could slowly and quietly click that back into place as well. He knew he had to do this, but if he was caught in here, his whole career could be jeopardized.

“Shining?” Cadance said, as she came trotting into her suite’s entryway. Despite how quiet he’d been, she must have somehow heard him coming.

He shrugged sheepishly and nodded.

Her look of surprise quickly faded into a more knowing, coy gaze. “Hmm... I didn’t think they allowed junior guard cadets into the royal housing wing of the palace, much less a princess’s personal chambers.” She came a little closer. “Who knows what might happen if such an inexperienced recruit were to infiltrate all the way into the royal bed itself...”

“Well, um...” Shining coughed a little as his nervous throat closed up. “Well, a certain door guard of yours might be friends with a certain favorite uncle of mine, so...”

“Oh?” Cadance was close enough to touch him now, though she didn’t yet. “Well then, I’ll just have to see about disciplining him...” She lifted a hoof and caressed down the line of his mane to his shoulder. “Right after I get done disciplining you.”

Her hoof was tracing farther along his back. Despite himself, he was starting to slip out of his sheath, just from the familiar, yet always-tantalizing smell of her perfume. He couldn’t let himself get distracted by what she obviously thought he’d come here for, or else he’d forget what he actually came her for. Which was ... was...? What was it, again? Oh! She was running her hoof right down his flank now, angling her body toward him and inviting him to do the same! Maybe just a little bit of—

“Hmm... Is there anything else I should punish you for, Cadet?”

Despite his cock fully hanging out of his sheath now and trying to do all his thinking for him, Cadance’s question actually refreshed his memory. Unfortunately. “Um, actually, there is something I really need to talk to you about.”

“Oh.” Deflating a little when she heard the serious note in his voice, she drew her hoof away. “Is something wrong? I thought you’d snuck in here to, you know...”

“No, no. Believe me, I am totally into it!” He turned and kissed her cheek, hoping she wouldn’t take this as a rejection or anything. “But there’s, uh... There’s a thing about my sister.”

Cadance giggled. “Uh-oh! What kind of trouble has little Twilight gotten herself into now?”

“Well, um... I guess she’s gotten herself into the me kind of trouble. It’s about the coupons we—”

A flash lit the room. When Shining blinked his eyes clear, he found Twilight herself standing right in front of him, looking up at him with an adorable – and terrifying – smile.

He suddenly darted away from Cadance, trying not to look like he’d just been kissing her. Cadance deftly stepped in front of him, hiding his burgeoning erection from his filly sister’s view. Cadance didn’t yet know, of course, about how Twilight had already gotten far more than a good look at it.

“Sunshine! Sunshine! Ladybugs awake! Clop your hooves and do a little shake!”

Hearing both of them do that silly little rhyme they always did when they met injected some much-needed feeling of normalcy into it for Shining ... though he was afraid it would soon be horribly shattered. How could he tell Cadance what had happened? How could he not tell Cadance what had happened? And how the heck could he possibly do either with Twilight right there with them?

As their rhyme ended, Twilight laughed happily. And Cadance patted her on the head. “You’ve been working on your teleportation, haven’t you?”

“Uh-huh! And look, I can teleport other things, too!”

Three smaller flashes followed. Three slips of paper appeared in midair in front of Twilight. Quickly, she grabbed them in her magic and held them up toward Cadance and him.

One free cream pie♥

One free mouthful of pussy♥

Drink my cum out of another mare’s pussy♥

Cadance’s eyes went wide. Her jaw dropped. “T-Twilight! Where did you get these?”

“Under Shiney’s bed!” Twilight beamed with pride.

Snapping her head around, Cadance gave Shining a sharp look. He returned an apologetic shrug.

“These coupons are so amazing!” Twilight continued. “Shiney taught me what a blowjob is!”

Another, even sharper, look came blazing from Cadance. Shining held his hooves up, begging for mercy. “I couldn’t help it – the hex!”

“And now I want to learn a bunch more!” Twilight grinned and bounced happily. “What’s a cream pie? It’s not an actual pie is it? Maybe I should have brought a different one...”

Ignoring her for a moment, Cadance turned fully toward Shining. “You knew your sister had found these, and yet you still left them under your bed?”

“No!” he said vehemently. “I had no idea she’d found them! And when I went to check, they were all gone!”

“All of them? No no no no. This can’t be happening! Why didn’t you search her room and get them back?”

Crap! He really should have thought about doing that! But where would he even start? “But she has literally tons of books in her room. The coupons could be hidden in any of them!”

Twilight laughed and blew a raspberry. “Silly BBBFF! I’m not gonna hide them in my room – that’s way too easy!”

Shining’s hooves shook. No... If not in her room, where? The library? The Canterlot archives? Celestia’s magic school? Or was Twilight creative enough to hide them somewhere else entirely? Oh no! What if somepony else found her hiding place? This could really be getting out of control!

Cadance, as usual, was handling things a lot more calmly though. “That’s so smart!” she said sweetly, patting Twilight on the head again. “What amazing hiding place did you come up with?”

“Nuh-uh!” Twilight shook her head. “Not that easy! They’re mine now!”

Only someone who’d been around her as much as Shining had would have noticed the slight wince on Cadance’s face, quickly hidden behind a comforting smile. “I see... But you know you’re not supposed to take things that don’t belong to you, right? You’ve got to give them back.”

“I will! Look, here’s three now!”

Shining could already feel the first tinglings of magical compulsion radiating from the hex enchanted into those three coupons. The longer they resisted fulfilling them, the stronger the compulsion would become ... the compulsion to march into an audience with Princess Celestia and publicly announce their dirtiest, most embarrassing secrets... He knew Cadance must have been feeling it too.

He gasped as the realization struck him. “Wait! If she gave us the whole coupon booklet at one time, would the hex count that as ‘presenting’ it to us?”

Cadance went pale, staggered backward a little. “There are ... there are things in there that I definitely can’t do with a little filly! And certainly not all at the same time!”

Shining nodded. “We can’t let her give it to us – we have to find it ourselves!”

“I’ll start working on a detection spell,” Cadance whispered back to him. “If I can detect a trace of the hex’s magical signature, that should lead us right to it...” She looked back toward Twilight. And the coupons. “Until then...”

“We ... we don’t have any choice, do we?” Shining hung his head lower ... and yet his cock stiffened more. Such an odd mix, to be feeling both lustful anticipation and nervous dread at the same time...

“I’m supposed to be a princess!” Cadance whispered. “I cannot, under any circumstances go confessing my darkest secrets in a public royal audience! It wouldn’t only be me who gets ruined – it would reflect badly on Princess Celestia, too!”

“Well I can’t do it either! My guard career would be toast! I’d never be able to show my face in Canterlot again!”

Twilight just watched the two of them expectantly, happily content, her tail swinging and swishing behind her.

Shining winced. “So, are we ... are we actually going to do this?”

“Do we really have a choice?” With a heavy sigh, Cadance stepped to the side, no longer blocking Twilight’s view of Shining Armor.

The view of his cock hanging down below his belly certainly didn’t deter the filly in the slightest – she leapt toward him. Thanks to her small size, she was easily able to slip in beneath his belly, where she started to lovingly lick up and down his length, rubbing her face all over it.

“Shining!” Cadance gasped. “She’s your sister! Why are you getting hard?”

He held his hooves up helplessly, which only gave Twilight even better access. “You said it yourself, we have no choice! I ... I couldn’t help it! She gave me that ‘one free blowjob’ coupon last night. And, well, she’s kind of pretty good at it, for a filly.”

Cadance raised one eyebrow. “Seriously, Shining?”

Beneath his belly, Twilight took his cock into her mouth, quickly swallowing it down until she’d managed to push her lips almost halfway down his length.

“Oh...” Cadance’s eyes widened. “She is pretty good.” Then she looked back up at Shining with a smirk. “For a filly. But let’s show her how a real master does it, hmm?”

Quickly, Cadance led him over to sit on the edge of the bed; it wasn’t easy, since Twilight would barely allow him to take his cock out of her mouth even for a moment. Once he sat there, he could barely believe his eyes as he watched both his girlfriend and his sister sharing his cock.

Twilight was greedy for him, which left Cadance with mostly just his sheath and balls to play with. Not that it slowed her down – she often liked to start that way, with gentle teasing licks and burying her muzzle deeply in his crotch. And as Cadance teased, Twilight sucked earnestly and diligently on his tip, scarcely even coming up for air.

Still not quite believing his luck, he reached down with both hooves, running one hoof lovingly through each mane. He knew better than to try and push them or take control. He just wanted some way to return a little bit of love and demonstrate just how much he was enjoying this.

Because, yeah. There was no denying it. Despite being only a filly, despite being his sister, he was really enjoying the feeling of Twilight’s second blowjob ... and the increasingly lascivious help Cadance’s tongue was adding to it just brought it way over the top. Definitely one of the best blowjobs he’d ever gotten! And that was saying something, because Cadance really knew what she was doing with that, and it wasn’t even the first time she’d had another mare to help her with it.

But, of course, it took a turn toward being even better when Cadance finally managed to edge Twilight up and out of the way. Cadance took his cock into her mouth in a very well-practiced motion, effortlessly swallowing it down into her throat and sinking her lips all the way down to his sheath.

Twilight pouted when she had nothing but his balls left to lick ... but Shining didn’t take much notice. He was busy trembling and shuddering as he once again felt the familiar heaven of his girlfriend’s throat expertly pulsing and squeezing around his length.

With a wet slurp, Cadance pulled all the way back until his tip popped free. Ignoring the pre-cum dribbling out over her lips, she looked down at Twilight with pride. “There. That’s how it’s done.”

But the itch in his hooves was getting worse. This wasn’t helping! “The coupons!” Shining said. “Cadie, we have to... Come on! We’d better get started before we find ourselves zombie-walking toward the throne room!”

Cadance nodded, causing his cock to bob against her face. “Right... So what do we need? A cream pie, a mouthful of pussy, drink my cum from another mare’s pussy... Hmm. Well, we can get both of those first two done at the same time!”

Shining’s eyes went wide. “You’re sure?”

“Well we don’t have much time, do we? Twilight, get up on the edge of the bed, dear.”

“Yay!” Twilight hopped up instantly. “This is so neat!”

“Yeah, well, don’t get used to it...” Shining slid off the side of the bed and came up behind his sister. Wow ... he really shouldn’t be doing this kind of thing, especially not with a filly especially not with her. But what choice did he have? And, well ... did he really not want to?

He looked down under her already-raised tail. Wow. Yeah, there she was. His filly sister. Right there for anypony to see. Specifically, for him to see. Of course he’d always known that his little sister had an adorable round little butt. That she had a cute and pert little vulva nested between those purple cheeks. Since she rarely wore clothes and rarely kept her tail tucked, that was all just a fact of life for a young stallion growing up with a little sister always around. But now, to see it winking up at him, flashing her pink inner need at him as it dripped her filly juices off the side of the bed...

“Enjoying the view?”

He snapped out of it at the sound of Cadance’s voice. “No! I mean, uh...”

She laughed a little and flopped onto the bed in front of Twilight. “Don’t worry, Shiney. Since we’re stuck doing this, you might as well enjoy it. I certainly intend to.” Looking back down to Twilight, she took hold of the filly’s horn with her hoof, drawing Twilight’s face down between her legs. “Wanted a mouthful of pussy, did you? You naughty little filly. Well here you go!”

Twilight squealed a little in surprise as Cadance forced Twilight’s head down, mashing her mouth against Cadance’s pussy. But that surprise quickly turned into an obsessive moan as Twilight started licking.

Shining’s cock throbbed at the sight of his sister eating out his girlfriend. If not for the look Cadance was giving him, he might have stood there dumbstruck and forgotten what to do. But that look in Cadance’s eyes! It was like she couldn’t wait to see him do it. Would seeing him mount his sister be as hot to her as watching the two of them was to him?

Screw it! Time to find out! He hefted himself up onto the bed, planting his forehooves on it to either side of Twilight’s small body. Standing on the edge of the bed, she was just the right height for him...

“Remember, Shiny, she’s very small. So be gentle.”

He nodded. “I know, I know.” But, honestly, it was a good reminder. His hips were practically thrusting forward all on their own, in an instinctual need to penetrate, to breed. His body didn’t care how young she was, didn’t care that she was his sister. It only sensed a tight, virginal hole to be filled, and it was desperate to complete the task.

The tip of his cock pressed up against something warm and gooey-wet. There wasn’t anything else it could possibly be.

“Are you, uh...” Shining took a deep breath. “Are you ready, Twiley?”

“Muh-hmuh!” Her response was muffled by Cadance’s pussy lips, but still clear and unambiguous.

Well ... here it goes. Steeling himself as if it would be painful, Shining forced himself to do what was necessary: to slowly push forward. Into his little sister. There wasn’t as much resistance as he was expecting. Twilight was tight, yes, moreso than any mare he’d ever been with, but very wet and seemingly eager to stretch around his girth. As he pressed carefully inward, his cock slid into her with ease and grace.

Couldn’t quite say the same for Twilight, though. She moaned and squealed as her brother’s cock claimed her virginity. And despite her being muffled by Cadance’s pussy, she was loud enough that Shining worried the guards outside Cadance’s suite would hear.

“Are you okay?” Cadance said sweetly, looking down at her.

Shining, though, had his eyes clenched shut and thought the question had been for him. “Yeah. She’s...” He grunted as he pushed in a little more. “She’s just really tight.”

Cadance laughed at him a little. “You’re enjoying this, aren’t you?”

Finally, he opened his eyes. He’d thought maybe he could pretend that it wasn’t Twilight underneath him, but he hadn’t really been able to convince himself of that, especially hearing her voice as she moaned. And as he looked past Twilight’s head to Cadance’s body, he could see the tell-tale twitching of her belly, the slight motions that meant an orgasm was brewing. He huffed. “Oh, and you’re not?”

She twitched even more when Twilight found her clit. And through her stifled moan, Cadance said, “Oh just shut up and fuck your sister.”

Hearing something like that out of his girlfriend’s mouth actually had the opposite effect for a moment – he froze. “W-what?”

“Which part were you confused about? Shutting up, fucking, or your sister?”

He looked down at Twilight. Looked at where his cock disappeared inside her. A lot of it was already in, almost to his medial ring. “Uh ... I guess I was just kind of surprised is all. By, you know, the whole concept.”

Cadance giggled. “I’m just giving you a hard time, Shiney.” Looking into his eyes, she winked. “Now give your sister a hard time for me, okay? She deserves it – she’s doing a lovely job with her tongue.”

Was it just his imagination, or did Twilight’s body actually squeeze him a little on the inside when she heard that compliment?

Well, anyway, what was he waiting for? He was already inside her, after all... Moving his forehooves to take hold of his sister’s little rump, he started to push into her again, looking forward to sinking the thick bulge of his medial ring through her tight entrance.

But it was not to be. After he sank just a little bit more of himself inside, Twilight suddenly yelped in pain, yanking her face up out from between Cadance’s hind legs. “Ah! Too deep!”

“Shining,” Cadance chided, “I told you to be gentle!”

“Sorry, sorry!” He pulled back, almost all the way out of her.

Twilight turned her head to look back at him, her muzzle dripping. “It’s okay, BBBFF. It didn’t hurt that much. Please don’t take it away. I really like it!”

“Sorry,” he said again, rubbing Twilight’s back. “I just, uh, didn’t expect you to be quite so small. I’ll be careful now.”

“That’s the spirit!” Cadance reached down with one forehoof and nudged Twilight back toward the task in front of her.

Apparently, Twilight hadn’t quite gotten her fill of pussy yet, because she dove enthusiastically right back in, lapping eagerly at Cadance’s winking slit, making Cadance moan and shudder.

It made Shining twitch a bit, too. In his cock, which Twilight surely felt. He couldn’t help it – she was just so cute down there, and it was so hot to see Cadance getting eaten out. Despite his own very excusable excitement, though, he made sure to restrain himself carefully as he pressed back into his sister’s little filly pussy. The last thing he wanted was to hurt her again. Thankfully, his big brother protectiveness instinct was stronger than his lust-fueled breeding instinct ... for now.

Still though, holding back wasn’t easy, especially as he started to get comfortable with sliding in just up to – but not beyond – Twilight’s limit with each thrust, beginning to build up a rhythm. If it weren’t for the fact that almost half of his cock couldn’t fit inside her, he would have had to admit his sister’s pussy was the best he’d ever had. Though, of course, Cadance’s still won out by a hair. Even as he thrusted into his sister, he could imagine the silky-warm feeling of Cadance’s soft, welcoming pussy as she effortlessly took his entire length. It sure didn’t hurt that he could look at Cadance laid out and trembling in building orgasm the whole time he—

And oh, crud – he was already starting to flare! That tell-tale redoubling of tightness deep inside was unmistakable, as were Twilight’s steadily growing moans. “So big...” she mumbled against Cadance’s pussy. When he looked down at her, he could just about swear that he a slight bulge moving up and down the sides of her body, following the movements of his wide flare deep inside her.

Despite the tight squeezing warmth of his sister’s most intimate depths, Shining managed to hold himself back pretty admirably. He grit his teeth and tensed his legs, forcing himself to keep the same slow, steady rhythm, never allowing himself to plow into her and hold his cock deep inside her like his instincts screamed at him to do. This was his sister’s first time, after all. He had to make it count!

What did him in, though, was the familiar siren song of Cadance reaching her climax. Cadance was never much of a screamer. Instead she had this series of low moans and gasps that would build, build, build ... and then give way to complete silence as her body tensed up past the point of no return. And then finally, finally a huge breathy gasp as her body went haywire and began to pulse uncontrollably.

So many times in the past, he’d held himself back waiting for that exact moment before allowing his own release. And now, the same habit took him over. Without even thinking, he pushed hard into Twilight until he couldn’t physically fit any more of himself into her. The instinctive need to breed and shoot his load of cum as deeply as possible overrode even his brotherly protectiveness. And then it came, throb after throb, thick jets of cum surging straight from his tip into his sister’s unprepared womb.

Twilight cried out messily against Cadance’s squirting pussy, and at first Shining couldn’t tell whether that was from pain or pleasure. Even in the midst of his orgasm, it hit him that what he was doing was so very wrong and he felt a sharp pang of panic that he might be hurting her.

His worries were relieved a mere moment later when the throbbing of his cock and the spreading swell of his cum inside her triggered Twilight’s orgasm. Maybe her very first? She squeaked adorably, and her pussy clenched down with unbearable tightness, strangling his cock as her body flexed inside, sucking his cum down deeper within her.

Still, she was quite a small filly, and he’d blown quite a big load. There was only so much her body could guzzle down before she began to overflow and leak thick streams of cum between her pussy lips and his shaft.

The cream pie had been delivered. He could feel the compulsion of the hex lessening ... but it wasn’t entirely gone. There was still one more coupon left to be satisfied.

Shining looked up at Cadance, who’d fallen back against the bed, heaving in deep breaths that made her belly rise and fall from chest to teats. He tried to remember what this coupon had been for. “’Drink my cum out of another mare’s pussy’ ... how do we even do that? Does that mean you have to eat Twilight out now?”

Cadance sat up. She shook her head. “I don’t think so. Since she presented the coupon to us, then ‘another mare’ has to be one of us, so it has to be me.”

That made no sense to him. “But how? We’d have to get this mess inside you somehow, right? But Twiley can’t reach herself with her mouth to pick it up, and you can’t reach yourself with your mouth to put it there... There’s no way it could work.”

“There is one way...” She looked at him.

It took a long time for him to get it. Embarrassingly long. “Wait ... me? With my own...? No way!”

“Well, unless you think you can do another round before the compulsion takes over us...”

Shining took a step back, pulling his now-limp cock – with some difficulty – out of his sister’s pussy. A thick glob of cum splashed out of her as his still-flared tip popped free and swung down. His own cum. Could he really...?

“Come on,” Cadance urged, “quickly! Don’t be a baby about it. I’ve had my mouth full of your stuff more times than I can count. You can do it just once!”

“Fine.” He took a deep breath and tried not to think about what it was he was doing. Or who he was doing it with. He just bent his head down low under some filly’s tail – who didn’t necessarily have to be his sister – and planted his lips against her winking and thickly dripping pussy. Then he slurped up a nice big mouthful of some warm, slimy stuff – that didn’t necessarily have to be his own cum – until he was sure that it would be plenty enough to share.

The foul taste of it did make him gag a little as he pushed past Twilight in order to reach Cadance, but he steadfastly refused to spew it out. If he did, he’d have to do this all over again!

Thankfully, he didn’t have far to go. Soon, he was in a very familiar place between Cadance’s hind legs, pressing his mouth against her pussy. It suddenly hit him how much bigger she was than Twilight ... and softer, too... But that didn’t matter – the important part was holding up Cadance’s legs and pouring the cum from his mouth into her. She made it easier on him by holding her pussy lips apart with her magic, allowing him to stick his tongue inside and simply pour it all in, flowing down over his tongue.

He got it out as quickly and thoroughly as he could. He’d have a new-found sympathy for Cadance swallowing huge mouthfuls of the stuff now, but he was ready to be done with this part!

“There!” He wiped his mouth. “There you go, Twiley. Now you can do like the coupon said and drink my cum from another mare’s pussy.”

Twilight, for her part, had watched the whole process with rapt fascination. And she didn’t hesitate in the slightest when it came to diving back down to Cadance’s pussy and slurping the cum into her own mouth.

Despite the lingering taste still on his tongue, Shining had to admit he enjoyed the sight. His cock, which had mostly retreated into his sheath, twitched a little, beginning to re-emerge.

But not fast enough. Soon, Twilight had finished her meal. She came up licking her lips and then smiling wide. “Thank you, Cadance! Thank you, BBBFF! That was the best thing ever!”

The compulsion of the hex was fully lifted! Such a relief! Shining took a deep breath, feeling like he’d just now gained the freedom to do so.

Cadance seemed more relaxed as well ... but also more focused. She sat on the edge of the bed, looking down at Twilight’s dopey grin. “Alright, little filly. We need to talk.”

“Huh?” Twilight’s grin vanished in an instant. She started backing away from both of them. “Actually, um... I should go check on ... a thing ... I think I have an overdue library book or maybe a—”

“Shining! Shield her!”

Instinctively following Cadance’s order, Shining instantly cast his shield spell – his own special talent that nopony could do better – around his sister.

And not a moment too soon. Almost before his shield was up, Twilight vanished in a flash of teleportation ... only to smack against the inside of his shield a moment later and drop back down to the floor.

“Ow!” She rubbed her head where she’d smashed against his shield.

Now both he and Cadance stood up, coming right to the edge of the shield and looming over her. He held his spell diligently in place. Twilight was very good at magic and far stronger than a filly her age should be, but shields were his own special talent, and even she couldn’t break through one of his.

“Twilight,” Cadance said sternly. “We need to talk about this.”

This time, Twilight didn’t attempt to resist. She just looked away and nodded.

Cadance glanced at Shining. He didn’t know what she was planning, but he could see the question in her eyes and he trusted her judgment, especially when it came to Twilight. He nodded back at her, already in full support of whatever she’d decided.

She turned back toward Twilight. “Now... I think we can agree not to tell your parents about all of this ... as long as you tell us where the rest of the coupons are.”

Twilight was still looking away. She shrugged.

Cadance’s face went tight. She gave Shining a desperate little glance.

But it was alright. He knew how to get through to his little sister. He knew better than anypony. He stepped to Cadance’s side and laid a hoof over her shoulders. “And ... maybe Princess Celestia doesn’t need to hear about it, either.”

Twilight snapped toward him, her eyes wide. “No! You can’t!”

“Oh? I think it’s pretty important that she’d know what her most faithful student is doing with these magical artifacts she’s found...”

Twilight blanched ... and then prostrated herself on the floor. “Okay! Okay! I’ll tell you where they are! Just don’t tell the Princess about it!”

He let out a deep sigh. A sigh of relief ... and maybe slight disappointment?
