Prologue

It was just an ordinary evening in the Crystal Empire. Lots of the city's residents are already getting back inside their homes while a few others might be on a honeymoon date of some sort or running errands before they get to bed. And of course there's always ponies who spends the night in sacred sexual intimacy.

For what the Prince of Crystal Empire is doing is the one of the most sacred of all. Crossdressing.

Sure it can be natural in Equestria when stallions crossdresses into mare’s clothing, and as stereotypes goes usually they would be gay. But this is different, Shining practically destroys multiple stereotypes about how a traditional or a gay stallion would usually act. Of course there are different ponies who has different behaviors so of course not all stereotypes apply to every pony. But when it comes to how Shining Armor takes it he always remain secretive about his little side hobby. He’s a prince after all, and the history of royalty is to always remain formal and meet high standards they usually put on themselves. If word ever got out that he likes crossdressing then he’ll feel like he won’t be able to live that down.

Later in the night Shining Armor was just trying on some mare intimates in a separate room from his wife as he’s in the bathroom. Nothing much except some matching red lingerie. He got them from one of Rarity’s boutique businesses when he visited Canterlot, but lied about buying them for his spouse, Cadence.

He tries on the red bra and panties to see if they fit for him. To his surprise he manages to fit the set.

Hmmm... fits... Shining thought to himself. He stares at himself in the mirror to see if he actually looks good in it. He glares at his outfit that he's trying on as he bites a part of his lip. He starts to notice a bulge down in his intimates.

Shining looks behind him to see if anyone was looking. Assuming the coast is clear, he slowly trails his hands down to his most private part of his body. He slips one hand up under his panties and holds the red intimates with the other as he grabs his fully erect member and starts to slowly jerks his hand back and forth. He slowly jacks himself off as his horniness kicks in. The mare like stallion closes his eyes as he starts to fantasize about Cadence and Twilight with him in bed. He imagines them having their strap ons as they attempt to double penetrate him.

hmmmm… fuck….. Shining thought to himself as he tries to stay quiet as possible so Cadence doesn’t hear. He couldn’t help but to moan a little a bit quietly as he jacks off his long inched cock.

Little does he know that Cadence was going to enter the room to use the restroom and Shining Armor forgot to lock the door.

The next thing he knows, Cadence walks in on him and jump scares him as she shocks herself as well. Both of them scream a little.

“AHHH!!!!! Cadence?! I thought you were still in the bedroom,” Shining looks away as his heart still beats faster from the jump scare.

“Well hon!… I needed to use the bathroom to do my mane but I didn’t know you were in here doing…” the mare looks and scans Shining’s body that’s dressed in lingerie. “…doing…are you wearing a bra and panties?” she asks. Shining keeps looking away, feeling a bit ashamed, his face turning red.

“…yes,” he murmurs quietly.

“What?”

“*sigh* yes,” he admits. “Just like to wonder how it feels to be… like a mare somewhat.”

“…oh,” she says in disbelief. “Well… I didn’t think you would think about it sweetie… Well maybe, maybe not but still.”

“I didn’t want anyone to know. I’m the fricking prince of the Crystal Empire for crying out loud who rules along side her loving princess.”

“Heh. Typical royal stereotypes,” Cadence snickers a bit. “Shining I don’t think you would have to worry,” she reassures him.

“Really?”

“Really. I personally think it’s totally natural to think about something like this. Heck I always wondered about having a dick.”

“Huh. The more you know I guess. I just feel embarrassed still,” Shining Armor blushes hard into a cherry.

“Hmm… actually I think I know some pony who would love to help you get more comfortable with this,” Cadence smirks.

“Who?”

“Hang on, I have to send out a letter,” Cadence leaves the room to go get a piece of paper and a quill that has some ink on it. She writes a letter to her one and truly loving sister-in-law, Twilight Sparkle.

As she completes her final words on her written message she uses her horn and triggers her magic and teleports the letter for Spike to receive. With done, Cadence goes back to Shining who changes out of his lingerie and exits the bathroom.

"Ok. I just contacted Twilight. I just set up a meeting for you two at her castle down in Ponyville."

"Twilight? Why should I go down to her place?" the unicorn asks.

"Don't worry you'll see," Cadence winks.

"Wait. Are you coming along at least?"

"Sorry sweetie I can't. I have to get Flurry to sleep for tonight. You should be able to the the last train of the evening down to Ponyville. You can stay there for the rest of the night and come back in the morning."

"Alright then. I’ll get dressed and be on my way then.”

“Love you, hon,” Cadence plants a kiss on Shining’s nose.

“Love you too,” he returns her affections.

After their conversation ended, Shining Armor changes into some casual wear and goes on his way to Twilight’s castle to visit there.

Meanwhile Twilight was getting something ready for Shining once they meet in her castle. Little does Shining Armor knows is that he’s in for a lustrous surprise.

Incestuous F**king

Incestuous F**king

Shining Armor leaves the Crystal Empire for a temporary night visit to Twilight. He disguises himself under his coat to avoid being seen by the other ponies who may be still out here walking to their homes, mostly so they don’t ask him where he’s going as of late.

He was able to catch the train to Ponyville before they decided to close up there. It took a while before it completed its path to reach the intended destination but eventually all that traveling is now finished as it arrives at the station. The stallion unicorn exits the locomotive and on the way he goes to Twilight’s residence. He decides that he isn't gonna walk all the way there so he uses his horn to use his teleportation spell. The blue glowing aura shines around as he disappears from the station and instantly arrives at her sister’s castle.

He’s a bit nervous about meeting Twilight here now. He wonders if his own sister would make fun of him for being a mare like stallion. Or even feel a bit uncomfortable with Shining's crossdressing scene to say the least. After just standing around for a couple minutes, he finally, hesitantly knocks on the door politely.

The two whole castle doors automatically open via Twilight’s magic to let his brother inside, then they close once both of them are in the same hallway.

“Hey, Shining,” Twilight says enthusiastically as she gives her only sibling a hug.

“Um… Hey, Twilight,” an unsure Shining Armor greets as he returns the hug. “So how are you doing this evening?”

“I’m doing good. Nothing much is happening in this castle really,” Twilight says. “So, Cadence messaged me about you coming here for the night.”

“yeah,” he says quietly.

“Apparently you like to… crossdress?” she asks.

“yeah.”

“Aaaaand you feel uncomfortable doing it around other ponies and you would like to talk it out with me about this little thing you do?”

“Yeah… thanks for stating the obvious there,” Shining chuckles nervously.

“Just summarizing the plot here,” Twilight sheepishly says.

“Well yes. I like to… crossdress… this is embarrassing,” Shining blushes.

“Oh no it’s not embarrassing at all. I mean it’s natural for any pony who likes to crossdress, Shining,” she reassures him.

“Well I guess. I still don’t feel comfortable doing so in front of others though. Also what type of a royal prince would crossdress anyways?”

“Oh please. I like following the rules but even I would have to say that some of those royal traditions don’t hold up nowadays,” Twilight admits. “But hey, I think I know how to make you feel comfortable to crossdress in front of your closest loved ones at least.”

“Really?” Shining says as he’s somewhat interested to hear the idea. “How so?”

“You’ll see me in my bedroom in 15 minutes,” Twilight leaves it off there and leaves to go to her bedroom. With that Shining Armor walks around the castle to kill some time.

Shining Armor arrives at Twilight's room after walking around the big castle hall. As he stands in front of the door he suddenly sees a big one on the floor with a note on it. He picks it up to read it as it says:

Shining, try the intimates I have for you in the bag. I have a surprise for you in my room. Sincerely, Twilight. ;)

The unicorn cocks an eyebrow as he looks in the bag to find a matching black bra and panties and a short sized shirt that's enough to expose his half of his anthropomorphic torso. He also found long socks that covered most of his hooves all the way to his thighs. He goes ahead to change his clothes in the middle of the hallway before he enters the room. After Shining has completely swapped his clothes, he puts his old ones in the bag and slides them aside.

With that, it was time to enter the bedroom. He hesitantly opens the door and enters before closing the door behind him.

"...hey sexy," says Twilight. Shining Armor looks towards the alicorn only to be in complete awe. The alicorn pony is wearing a button up shirt and some booty shorts. The way her wear matches her nearly-perfect curves and how authentic her body shape is. The unicorn blushes with all his deer as he triggers a bulge down in his undies. "Love the sight?"

"Um... uh... wow... fuck I don't know what I'm saying," a flustering Shining blusing into a red cherry as he puts his hand on his forehead as if he's sweating.

"You kinda sound like Fluttershy whenever she's about to have sex," Twilight says as she draws heself closer to her older silbling.

"So this is what you meant by helping me be comfortable huh?" Twilight gets closer to Shining as the huge gap between them obliterates itself. Within a matter of seconds Twilight slows down her pace and stops right in front of him, their lips only mere inches apart.

"What did you think I meant?" Twilight destroys the gap between their lips as she gives her brother a passionate kiss. Shining Armor, who's a bit surprised, melts into the kiss and returns the favor. The two siblings make out on the spot as the alicorn caresses Shining’s blue mane. The stallion puts one hand on Twilight’s ass while the other is also running through her hair. The two ponies break the kiss after a minute to catch their breaths for a bit.

“I didn’t think you knew how to kiss that well,” Shining says as his blush is still visible on his face.

“Practiced with Rainbow Dash and Pinkie Pie. Even practiced with Starlight and Sunburst,” Twilight says as she sheepishly blushes. “But enough about that subject. We’re gonna have fun tonight exploring each other’s sexual anatomy.”

“Still nerdy as usual,” Shining teases. “I think I’ll be just fine for the night.”

The sibling ponies give each other another passionate kiss, only this time it’s in a more sexual and luscious nature. Twilight gets swept up by Shining Armor so they can take this to the queen sized bed to continue satisfying their sexual urges.

Twilight takes control of the scene and puts Shining on the bed while she’s on top. They make out on the bed as they give each other clean then sloppy kisses. Shining Armor tries to slip his tongue inside his sister’s mouth and Twilight grants him the entry. Their tongues go around exploring each other’s mouths, licking and sloshing around in their tunnels. They moan inside each other’s mouths as their kisses get more heated and sloppy. The two ponies break the kiss so the alicorn can unbutton her shirt at a slow pace. She unhooks the buttons one by one until eventually reaching the final one. Once she finishes up with the buttons she takes off her shirt and tosses it aside, showing her exceptionally big rack under her bra. Shining can’t help but to gaze at her big C cup breasts that’s held up by her tit covers. Twilight feels and caresses her boobs for Shining to watch.

“Like these girls?” she asks in a seducing tone with a sultry smile.

“My one weakness,” Shining Armor says as he practically drools at the sight of her titties.

“Hehe… go ahead, feel them,” Twilight tells him as she reaches behind her back to unclip her bra and takes it off and tosses it aside. The white skinned pony raises his hands and puts them on her breasts. He starts groping and giving these big purple marshmallows some attention. He decides to give them a little squeeze, causing his sister to moan a bit.

“A-a-ahhh….. shit…” she moans.

“Feels like soft pillows,” Shining says.

“Wait till you put your face in between them,” Twilight lowers herself down to Shining’s face and smooshes him with her big melons. He instantly melts into her boobs as Twilight wiggles them a little bit with his face still in between them. The stallion moans a little as he feels like he’s in the heavenly clouds. The purple alicorn lifts her breasts off of his face so she doesn’t end up suffocating him.

“…shit,” he says as he tries to catch his breath.

“The fun doesn’t end there,” she says. She signals her brother to take off his top and he tosses it aside, revealing his decently muscular skin. The two ponies reposition themselves with Twilight laying on her back while Shining Armor lays on his belly. The mare uses her magic to put a spell on herself as the glowing purple aura around her horn grows Twilight her very own horse cock. Her flat crotch turns into a large bulge showing in her short tights that’s in it’s raging erection. The stallion crawls closer to her crotch to get a closer look at her bulge. “Well? What are you waiting for? I didn’t do this spell for you to just sit there.”

Shining Armor licks his lips a little and goes in for the prize. He grabs the hem of Twilight’s tight booty shorts and attempts to pull them down to take them off, the mare wiggles her hips to help him get them off easier. The stallion is able to pull them down just enough to reveal his sister’s homemade purple shaft made from her magic.

The older sibling wraps his mouth around the tip of her younger sibling’s cock, eliciting a quick moan from her. He sucks on the tip a little and swirls his tongue around it as well to earn the same effect from Twilight, only a bit increase in sound in her moans. With that done, Shining Armor starts to take half of her scrumptious cock inside his mouth and then takes some of it out, only to take some of it in once again and so on. He starts bobbing his head up and down, triggering more moans from Twilight as he continues sucking her off. The alicorn’s horny level is getting fuller from the given blowjob from her older brother.

“Oooh fuck… Yees, Shining….. hmmmm,” she moans in her lust and pleasurable state of mind.

“Hmmm hmmmm hmmmph,” Shining moans onto her tasty hard lollipop. He takes his mouth off of it and jacks it off with one of his hands. “Ahh. Fuck… I wish Cadence was here. Then we could’ve sucked each other off all night,” he says.

“Ahh… fuck… we should do sexual activities whenever you two visit here,” she points out. “Let’s change positions shall we?” The two ponies reposition themselves as they lay on their sides while Twilight lays beside Shining’s crotch and he lays down beside her dick to make the 69 position. Twilight uses her magic to easily take off her brother’s undies and toss them aside, revealing Shining Armor’s raging erection.

The relative ponies took each other’s cocks and bobbed their heads back and forth on each other’s crotches. Both of them immediately moan onto each other as their privates have more pressure put on by the two performing fellatios.

I don’t know why I’m doing this… but fuck it… Twilight tastes amazing. Shining says internally in his mind.

Hmmmm… His cock tastes good… Tastes a little bit like Cadence to be honest. she says in her head.

The two moan in pleasure as they feel like they’re getting a bit closer to the edge. One was already thinking about what the other was thinking so for the climax of their sex scene they have to cut the 69 short. They took their dicks out of each other’s mouths and sat up on the soft bed to reposition themselves once again.

“So should I go for it first and do you want to,” he asks.

“You can penetrate my insides first. But I’m on top,” Twilight answers.

“Heh. Of course Twily.”

Shining Armor lays down on his back once again as his cock is still in its full erection. Twilight moves herself and hover over her brother’s long inch cock and aligns her blossom with it.

“Ready?,” she asks as he nods his head. “Heh, let's ride.”

Twilight puts Shining Armor’s member inside of herself as slowly as possible. The tip and a little bit of the shaft makes its way into the purple skinned alicorn, impaling her insides. She then tries to take all of it in and pushes herself down instantly on Shining’s crotch, triggering a sharp gasp. She hops herself up and down on the stallion’s penis, makes the queen sized bed slightly move and rocks itself by the motion. The unicorn attempts to thrust his hips as well as following the rhythm of Twilight’s humps on his member.

“Hmmmmph…” Twilight moans from the feeling of her brother’s appendage inside of her love tunnel. The older sibling fucks his own sibling all while he also puts his hands on her ass and gives them a little squeeze in the process. He just about grunts a little from the pressure of Twilight dry humping his shaft, going at a somewhat faster pace. The pony princess lowers herself down to give the Crystal Empire prince some kisses on his lips as the prince’s arms are wrapped around her. Eventually Twilight would use her magic to Jack herself off on her own cock while in the middle of the two ponies love making. All of the moans, pants, and grunts fill up the entire room as they pace things a bit further.

“Aaahh… ahhh… OH FUCK!!!” she screams out load as her horniness level goes through the roof. The faster they went, the more the bed rocks a little in the process. The both of them moan in pleasure and ecstasy as they continue their fucking each other and start to sweat a little. “Hmmm… Shining… it’s your turn,” Twilight whispers in Shining’s ear.

She takes the unicorn’s cock out of her and he flips himself over to make the doggy style position. The mare gets her cock up and ready to penetrate Shining Armor with all of her might.

“When I’m done with you, you're gonna be addicted to some mare cock,” Twilight leans in to whisper in his ear once again.

Shining braces for impact as Twilight pushes her big member straight inside Shining’s ass. Shining yelps out load as his young sister penetrates the fuck out of him. The horny mare pulls and pushes in and out of his ass slowly and then picks up the pace a little.

“Hmmmm did that feel good, Shining. The least I could do for having fun memories with my only sibling,” Twilight whispers again, seducing her already horny brother. She uses her magic to do the same thing she has done a bit earlier. She uses it to also jack off the stallion’s penis while she’s bucking him wild.

“…hhhhaaaa fuck…now I know how Cadence feels,” Shining moans from Twilight’s penetration.

“Hmmmmm… you know you wifey loves… you know your wittle sibling wuvs you… cause you know we love to wuv you… hmmmph,” Twilight practically had enough. She was gonna show if not the entire world how horny she could possibly be in situations like this.

She fucks him harder and faster like never before, penetrating Shining’s small asshole with every ounce of energy she can possibly give out. The two ponies moan and scream as if they’re just making noise inside of a void. Their sounds feel like they’re echoing in each other’s mind or echoing into the abyss of a rabbit hole. Every thrust, every moan, and every pleasurable sound they make is one step closer to their climax.

“Hmmm that’s it… hmmmm. We’re gonna cum all over this bed,” she says seductively as they’re just mere moments from their climax.

“Hmmmmmph… fuck!!!… I’m… ABOUT TO CUM!!!”

“GGGGRRR ME TOO!!!”

The two siblings moan and fuck as hard as they possibly could.

Twilight thrusts into Shining Armor a few more times and jerks off his dick until the exact moment she and him climaxed. She held it in her cock for a bit longer until one final thrust did the deed. The alicorn’s cock erupts inside of the unicorn stallion along with the stallion’s penis cumming on the bed as well.

Both of them collapsed down on the bed beside one another as they were completely spent.

“Wooo… that was a good intercourse,” Twilight says as her magic cock wears off and disappears from her crotch.

“That was pretty fun. We should do this again when Cadence is with me to visit you,” Shining suggests.

“Or if I decide to visit you two, whichever comes first,” she replies.

“Welp, I’m spent… I’m gonna catch me some sleep,” he says as he wraps his arms around Twilight and she does the same. “Night, Twily.”

“Night.”
