While trapped in the Crystal Caverns underneath Canterlot. Princess Cadence goes into heat, and the only one around is you. Her personal guard.

It's been a few days since Queen Chrysalis trapped Princess Cadence down in the Crystal Caverns beneath Canterlot. Luckily, you were also captured with her so you know she's safe. The bad news is, you are stuck as well. As you both search for a way out, you can't help but notice the looks she gives you. And the smell of cotton candy that keeps getting stronger is really messing with your head...

It couldn't be coming from her, right?

Hey all! This is just a little bonus story for my fifth anniversary! That's right I've been writing fanfiction for a whole five, damn, years. You'd think by now I'd be good at this eh? But anyways, this was a viewer request story. They requested the clop and build up. Not so much story, mostly focused on clop. First time with a new pony/scenario so I hope I did it justice. It's a fairly light story compared to what I normally do, but I hope you enjoy it otherwise!:twilightsmile:

Contains: Cheating/adultery, vaginal, sort of Femdom, little forced, heat, tiny bit of musk,
and cowgirl position, creampie and getting caught in the act.

You can find a live reading of this story right here!

You'll also be able to see whenever I live stream, as I don't want to clog my blog feed with them. If you've ever thought: "Hmm, boy I sure wish I could see what this Syn guy sounds like... And scream like a little girl playing games. " Then boy do I have news for you! Follow my Twitch channel here and get notifications for when I go live!:eeyup:

Again, a shout out to my editor, BlazingMoon for doing the editing on this story. I had to rush a little bit by the end to get it edited before some things came up. And he got it done for me, thanks again man!:rainbowdetermined2:

FEARURED: June 24th/2018-June 26th/2018. Reached the very top spot too!, I sincerely can never thank you all enough for this!:pinkiegasp:

Between a rock and a Princess

How much time had past? A day? Maybe two? Hell, it could have been a week for all you know. Your legs burned, wandering aimlessly for however long has taken its toll on your body. But you can’t stop, leaving your position next to the Princess would be breaking the one task you had. Protect and serve the Princess at all costs. Footsteps and hoofsteps echo loudly in the crystal cavern you found yourselves in.

Though it was quite dark, as most of the sparkling crystals had been mined and the place forgotten to the ages. A simple magic light from the tip of the mares horn ensured you both could at least see. There were a few old and quite honestly, rickety minecarts and rails still litter the cavern. But none seemed to lead to a way out. “Come on Anon… It has to be this way…” The pink pony ahead pants in exhaustion slightly, scraping her golden shoes against the rocky floor.

“My Princess; it is ill advised to for you to drag your royal shoes. There would be no way to get them repaired before the wedding takes place.” The pink alicorn let out a frustrated groan then collapses onto the dusty floor. You just had to mention the wedding, you think tonight was the night of it… Maybe it was tomorrow? Your sense of time was quick to fade away the longer you spent down here.

But regardless, Princess Cadence was set to marry Shining Armor. Captain of the Royal Guard, and in all intent and purposes, your boss. Apparently she used to be his little sisters foalsitter, so they’ve known each other for a long time. Deep in the back of your mind you’re a bit jealous, but you’d never tell a soul. They were happy together and as long as she was happy, you were doing your job correctly.

A whimper seems to come from the alicorn, snapping you from your thoughts. Cadence has her forehooves over her eyes, tears trickle down her cheeks and your instantly feel like someone stabbed an icicle into your heart. “I-I was supposed to be married…” Without thinking you gently rub her neck, kneeling beside her.

Taking a few seconds, you think about what you’re going to say. “We’re going to make it out of here, besides, your little sister-in-law is in Canterlot right? Surely her and your husband will see through the ruse. It’s only a matter of time before Princess Celestia and Luna take down the changelings and find us. I’m sure they’re already looking for us now.” Surprisingly this seems to calm her down, but you know her all too well.

Cadence is exhausted, just as you are. Her mane is disheveled, her coat stained with dust and dirt. Her eyes are dull and almost vacant, her wings hang limply at her sides with askew feathers. With no other choice, you take a deep breath and lift her up. She’s thankfully light, but offers no help as you lift her across your shoulders. “We’re getting out of here Princess, you have my word.” With that you set out once again, wandering the seemingly endless halls in search of the exit.

You never expected to last this long. You’ve been at it for hours, it’s been one movement before the next for quite some time. Your body is beyond tired, your strength wanes, but your spirit is ever strong. Princess Cadence's hot breath in your ear urges you to continue on. But your energy is broken, muscles are sore, but thankfully nothing’s broken… Yet anyways. “P-Princess… I-I can’t go on anymore… I need to stop.” With shaking hands, you lift her from your shoulders and place the pony onto what looks to be an old resting stop.

Once she is comfortable you collapse in a heap, panting for breath as your eyes close. You estimate you just walked for over three hours with her on your back. Let the sweet embracement of death take me away. A few clangs of metal reach your ears before a soft hoof gently touches your shoulder. “Thanks Anonymous, you’ve done more than your duty this evening.” Her hoof lingers for a little longer before pulling back, but not before brushing your cheek.

With beads of sweat trickling down your face, you open your eyes to look up and Cadence. She’s staring at you with half lidded eyes, her nostrils flare a few times as she takes a couple of deep breaths. Her light purple eyes scan across your chest and down your stomach. A faint blush spreads across her cheeks before she seems to jolt to attention. Quickly averting her gaze, she clears her throat and bites her lip. “T-thanks again. I, um… N-never mind. Night!”

With that said, she quickly turns over and starts to loudly fake snore. You’re a bit off put, but you’re too tired to question it. You remove your now ripped and dirty shirt, only imagining what the royal seamstresses will say to you. Not wearing any kind of armour made you feel a bit exposed, but you had no other choice. Using your now discarded shirt as a pillow, you tried to get as comfortable as possible to try and get some sleep.

You don’t know how long you slept, but it wasn’t long. A quiet whimper quickly snaps your attention to life. The Princess is in trouble! Your training kicks in and you immediately roll to your feet. Taking a defensive stance, you wobble a bit on shaky legs and with a blurry vision, try to see the attacker. But there isn’t anyone. Princess Cadence raises her head quickly, blinking her eyes to focus on you.

Cadence is sweating a bit, although the air was cool she’s visibly flushed As you catch her eyes, you see something deep inside them. Hunger. But not a look of hunger you’ve ever seen. “It’s ok Anon, I was just….” She pauses, her eyes trailing down your chest to your crotch with a smile. “Thinking.” Licking her lips she uncurls herself and starts slowly approaching you.

This is a little creepy, you back away while trying to find your words. “A-are you feeling ok Princess?” As she comes closer and closer while her tail flags higher and higher. A spicy smell, almost like cotton candy in a way, instantly invades your nostrils. Within a few moments, a sudden realization comes and it feels like a rock got launched into your gut.

She’s in heat.

Princess Cadence is in heat, and you’re both stuck down here away from her husband. The way her eyes hungrily judge you like a lion does a slab of meat makes you very uncomfortable. You gently bump into the wall behind you and she is instantly nuzzing your stomach. Cadence takes a deep inhale, rubbing her cheek all over your skin with a look of bliss. “You’re scent is so, intoxicating Anon~.” The pink princess works her way down and buries her nose right in your crotch.

You can’t do this, Shining Armor would kill you for taking advantage of his wife. Hell, Cadence would probably sic her aunts on you once she realizes what happened. As gently as you can, you grab her horn to pull her face out of your crotch. The smooth horn is warm to the touch, it fills your hand and provides great leverage. The alicorn lets out a squeak of surprise when you jerk her away, shivering as her horn seems to pulsate in your hand.

Now with a few feet of room between the both of you, you step around her getting away from the wall. “Knock it off Princess, think of what Shining Armor would think. Your husband.” But sadly it seems reasoning with her seems off the table. With now flared wings, she once again sets her eyes on you.

“He’s not here is he? Right now all I see is a nice, healthy, stallion who’s gone far too long without a roll in the hay, and little ol me~.” With a cheeky smirk, the princess of love gets ready to pounce. With her rump lifted in the air, a little wiggle and she bounds at you.

But you’re most definitely quicker. A quick sidestep and a small redirect with your hands later, Cadence loses her hoofing, almost tripping over her own hooves. Clearly she didn’t expect you to move so fast. “You’re feisty. I like my stallions feisty.” Undeterred she tries again, lunging at you like a cat would to its prey. Which is exactly what you feel like.

But you’re ready for her once more. Slightly angling your body to her, you let her slip past only to grab hold of her neck with your arm. Pinning her to your side as you squeeze in a headlock. You only hope this doesn’t get you banished to the moon or something as you hold Cadence tightly.

She puts up a good fight, twisting and turning to try and throw you off. But you’re much stronger than her. Cadence’s cheeks flush red while she struggles to inhale. Just a little longer and she will be out like a light. Maybe once she’s unconscious you can make an escape, find your way back to Canterlot. You’ll be able to find help there and… A low moan escapes past her lips, snapping your attention to her tail as it lifts high.

While you were distracted she nips your bare side, loosening your grip enough for her to wiggle out. The mare coughs a few times, weakly smiling up at you with her tongue out. “Shining says I can hold my breath for a long time, you know.” While you debate to turn tail and try to out run her, she quickly turns and spreads her hind legs. The Princess’s full musk hits your nose for the first time as she presents herself to you. “I’m also told I’m good in bed, but you can be the judge of that~.”

You quickly nope and turn tail to run, but you immediately trip and fall to the floor. With the wind knocked from your chest you struggle to get air. Cadence giggles behind you, her hoof steps coming closer and closer. “Sorry about that Anon, but I couldn’t let you try to get away again.” You try and stand again only to find your feet seemingly tethered together. Then it hits you with a feeling of dread.

She tied your boot laces together.

The mare straddles your back, laying her sweating body against you. You feel her chest rising and falling with her breaths, her fur tickles your bare skin while her muzzle is pushed against the back of your head. One last shot. “Come on Princess, think of Shining Armor. Your husband.” Her soft lips touch your left ear, she even kisses it a few times making you shiver. You can’t help but feel the surge of pleasure that washes over you. “Please Cadence… Don’t make me do this…” In your mind all you can see is a little pile of ash, that’s all you will be after Shining blasts you to oblivion.

With that said, she takes your ear between her teeth and pulls. It hurts a lot, but she holds fast as you weakly struggle. “Listen…” She says through clenched teeth. “I’ve waited many years for this… I’m a mare, not a saint. I’ve been very patient, but I can’t wait any longer.” With that she lets go and rolls you over roughly. Now that you can look at her, you see the fire in her beautiful eyes. “If Shining can’t get it up for me, then I had to find someone who can.” Her hoof firmly places itself onto your bulge. “So either you will give me what I want, or I will take what I want.” Now you can only think. She stands above you with authority you have rarely seen, her wings are flared and slightly pulsating.

After a few seconds pass, no other noise then both of your breaths. You slowly raise your hands up and grab her shoulders. Cadence tenses a little bit, her eyes darting between yours before you pull her chest to yours. Your hand rest in the middle of her back, just above her wings. No words are spoken as you feel her body twitch. She shifts on her hind legs while a wet spot grows on your leg.

Her cheek rubs against your as she whimpers into your ear. “It hurts Anonymous. Please.” You can’t do this. It goes against everything you’ve been trained for. All you’ve come to know about being her personal guard. But she needs your help, her fur stands up on end as her tail swishes vigorously.

No matter what happened, or where you are. Your duty still stands. Protect the Princess at all costs. Serve her, and make sure she is fully happy. You hesitantly kiss her cheek, feeling the warmth of her flushed skin on your lips. “I’ll do whatever you need Princess, as your guard I shall hold my oath to serve.”

She merely turns around to show herself to you. Her fluids trail down her inner thighs, her clitoris throbs as it winks at you. Her pink insides peek out slightly as a shudder runs down her spine. The musk is almost overwhelming. Even your comparatively weak smelling nose picks up her scent. It's smells a bit like strawberries and cotton candy. Sure you've caught a few glimpses here and there of mare bits, but this is the first one presented to you on a silver platter. Cadence looks so vulnerable right now, she's turned her head to look at you with hazy eyes.

Your princess needs you. With a deep breath you sit up, putting you face to pussy with her. Her hips twitch as your breath tickles the outer lips. With an up close and personal view, one thought comes to mind.

Shining is one lucky bastard.

Cadence looks perfect. She has a very slim figure, but up close you can see her rump is still curved nicely with a little roundness. Under her, you can see her small teats. No bigger than tennis balls with very erect nipples. You grip her tail by the dock which earns a soft moan from the mare. From her smooth dock, to her perfect pucker. Her untouched depths down to her quivering clit. If this is the last thing you do before you get obliterated, or banished. You'll savor every damn moment of it.

Gently placing your other hand on her lips, you feel just how soaked she is. Using your fingers you spread open her petals eliciting a surprised gasp from their host. Then you see the one thing that instantly gets you hard.

She has a hymen.

A very thin piece of skin blocks your view any deeper into her. She's pure, untouched by any other stallion. “Cadence…” There's a moment of hesitation but she is not standing for that. She pushes back suddenly, burying your face into her spread pussy. The taste is one you'll never forget. Her juice tingles on your tongue as you lap at her folds. All of your inhibitions go out the window as you eagerly begin eating her out. Her moans spur you on. Clenching muscles hug your tongue each time you drive it deep inside her.

“Ohh~” Cadence’s voice reaches your ears but it barely registers. Using both hands now, you spread her wide as you can. She winks hard, her clit throbbing for attention. Admiring the view for a split second before diving back in. She gently rocks back and forth, moaning every few seconds as you explore her canal with your tongue.

But not too long after you start, you feel her body start to quake. “O-oh Faust…. I'm going to-!” A surprise burst of a viscous fluid finds its way onto your tongue. It tastes slightly salty, but still delicious nonetheless. As you set to clean her, you feel a bump on your chin. Now your eyes are set to her love nub and you attack. When it winks past it's protective cover you seal your lips around it. A loud squeal of delight comes from Cadence as you suckle. Her bean quivers as your tongue lashes at it again and again.

The princes shifts from hoof to her, letting her rump grind against your face. “Buck yes… Right th-ah!” As you rub down along her innards, you feel her magic take hold of the back of your head. Effectively pinning your to her backside. A series of squeaks and a high pitched screech left your face coated in her marecum. It tasted even sweeter then before surprisingly. Soon her front end collapses while she pants hard for breath. The sight of those sweet lips parted to show the un-touched barrier inside the tunnel. Scooting back a bit, you take a few moments to catch your breath.

The only sound right now is Cadence breathing in and out rapidly, she babbles a little while her rump twitches every so often. But it seemed she wasn’t done. With a grunt of effort she manages to push her front end back up. Turning around her eyes set onto the now very noticeable bulge in your pants. A quick flare from her horn tore your pants and underwear clean off. “Now lay back and let me do all the work.”

The pink pony now straddles your hips, her wet marehood touches the tip of your cock. Hands imminently find their way to her cutie marks to help stabilize. As soon as she lowers herself a bit more, you can feel her inside part as your length sinks in an inch. Her forehooves rest on your shoulders and she gazes into your eyes. “Please be gentle… It’s my first.” The soothing sound of her voice is calming.

Putting one hand onto her cheek you gently cup it before pulling her face to yours. “Of course my Princess.” With a gentle kiss, you pull her down hard and spear inside. There is little resistance as your pointed tip easily tears though the thin web of skin. A sharp cry of pain is caught in Cadences throat, her body goes rigid before you stop pulling her down.

A few moments pass, allowing her canal to get used to your size. A few tears run down her cheeks, your thumb rubbing them away. “You are my first Anonymous. Shall we continue?” As if she even needed to ask anyways. With a short pull up, the princess lets herself sink even lower. With about half your shaft into her, you can’t imagine how you haven’t busted inside of her yet. The silky hot walls clench tightly on your cock, making her riding almost uncomfortable. Then a pain wells in your groin, when your eyes shoot down to see why. Your heart speeds up at your eyes no longer see a speck of your shaft.

Cadence took every, single, inch. Your tip must be crammed against her cervix. The thought alone makes your manhood throb which makes the mare gasp as you spread her that little bit further. “Oh maker above, you’re big.” Her cheeks are flushed brightly red, wings stand at attention on either side before she pulls up. With only the tip left inside, she let’s her body slam back down.

Wet, dear god she’s wet. While she continues to ride your throbbing pole those juices soak all it touches. Your shaft, balls and even the ground below you are soaked in her fluid. You never realized that a mare in heat would be be so cock-hungry. But you can see it in her eyes, mostly because they continue to stare into yours.

They almost close a couple of times when your thrust up to met her. The wet squelching noise of your actions, fill the soundless caverns as you both buck harder and harder. Ever approaching the euphoria that only an orgasm can bring. You’re sure she’s had multiple small ones by the way her back legs vibrate. But she never stops, in fact she seems to ride harder and harder. “F-fuck! This is amazing!~” The way her velvet walls ripple up your cock sends a tingling sensation to your balls, and you know what's coming.

Tapping her thigh with your hand to catch her attention, you try to hold back at much as you can. “Cadence, I’m going to cum soon!” A sly grin crosses her lips before she suddenly turns one-eighty on you. The twisting sensation is the last you can handle. Gripping her rump tightly as she suddenly rides harder and faster than ever before. With her wings flapping slightly, her head turns to look back at you. Her back is arches sharply, her insides clamp hard almost to the point of pain. But you’re past your limit, grunting in pleasure you thrust up while pulling her to you. Holding yourself deep inside, with your tip almost parting her cervix, you cum. You cum hard.

Biting down on her mane, Cadence squeals loudly while the first burst of spunk squirts inside her. “I-it’s so warm! C-cum inside me more! Please!” Your vision turns white, the only thing that mattered was here and now. Your manhood buried inside her previously untouched marehood. Walls milk your shaft for all it’s milky load, rope after rope of sperm being shot straight into her womb. If you were a pony she would for sure be pregnant. This has to be the biggest load you’ve ever had as you soon feel it seep past your tip.

Her depths are full and you’re still going. The mare grinds against you as the last few shots come to a dribble. Holding the princess tightly you fall onto your back while still inside. A few minutes pass as the two of you come off the high, but she is the one to first speak. “Thank you Anonymous. The burning sensation is far gone, and now I feel. Gosh I feel amazing!” Only a small smile crosses your lips before you kiss behind her ear.

Suddenly, what seems like far away yelling can be heard before a loud blast blows out the wall across the room from you. Standing in the rubble is none other than Twilight Sparkle. An angry scowl is on her muzzle as she comes closer. Cadence immediately flips off, letting your spent manhood slip out. “Twilight! You don’t know how happy I am to see you!” The shocked look on the unicorns face as she sees your exposed bits almost makes you chuckle.

Cadence looks a little scared that perhaps Twilight didn’t believe she was who she looked like. But an idea suddenly pops into her head. “Oh! Sunshine, sunshine! Ladybugs awake! Clap your hooves and do a little shake!” As she goes through the motions with an unresponsive Twilight. The Princess inadvertently then shows her now cum leaking marehood to the purple unicorn.

There is a few moments of silence, while the gears turn in her head. Only a few, short words come can from her mouth. “Cadence…. What. The. BUCK?!?!?!”
