> Day Special Containment Prisoner
> Turns out, Equestria is something of a dimensional hotspot. 
> The pony homeworld is a long abandoned rock, sorta like how Mars was briefly hospitable, before everything cooled down.
> The heartswarming pageant is as close as they get to stories of that place.
> They are lucky they stumbled plot-backwards through a handy dimensional rift, given their low tech level.
> Point is, by the time you and your little house Dorothyed from the upper atmosphere, ponykind has gotten pretty good at catching and dealing with dimensional travelers.
> They even caught your house, so you can live in semi-normalcy during your containment period.
> During this time, you have been on the receiving end of a barrage of tests to measure your magical capabilities, and nearly as many tests making sure you are not a shapeshifter.
> Chrysalis messed them over pretty good, you gather.
> It's not all bad, some of the researchers are pretty cute, and you get semi-regular visits from Celestia.
> That's the other thing. It may be a while before you enter the general populace.
> You are designated as an oracular anomaly, by virtue of showing up right before the events you know as "Ticket Master".
> Celestia only sending two tickets? That's your fault. 
> She didn't want to cause a paradox, and she did like the episode's outcome.
> Of course, most researchers are unaware of your show knowledge, and Celestia has sworn you to secrecy.
> As a sunfag, you actually take that seriously.
> So, right now, one of the scientists you've had your eye on is poking you with with a magic stick that activates pleasure receptors.
> You've been fairly appreciative, and the blue mare is starting to lose her scientific indifference.
"Oh, oh yes, that's good."
> Proper Procedure withdraws the stick from poking your waistline, setting it back in its case.
> "I-I think that will be all, for today. Thank you for your, ah, cooperation."
> She absentmindedly brushes back her chin-length white mane, which reminds you pleasantly of Scully.
"You're welcome. Any time you want to run this test again, I'm up for it."
> She glances at your pants, and replies.
> "I can see that. I MEAN I see, I'll, uh, keep that in mind."
> As she leaves, you can't help but stare.
> She had cut her tail short, as a practical measure against accidents in the lab.
> As such, there wasn't much that you couldn't see, when she turned around.
> You're pretty sure the research administrators had noted your unusually docile behavior, and had made her the primary performer of your tests.
> Fine by you.
> Proper Procedure pauses on her way out, as the door opens from the other side.
> "P-princess Celestia!"
> Proper bows, and Celestia enters your containment chamber.
> "Hello, Doctor. I trust the examination went well?"
> Proper glances at you, color rising in her cheeks.
> "Yes, I was able to gather all sorts of data."
> Celestia smiles.
> "Glad to hear it. But I've kept you long enough, go ahead and give the team my regards."
> Proper bows again, and scurries off.
> Dat rump.
> You turn your attention to Celestia, only to find that she is also staring after the young researcher.
> Interesting.
"Don't you just admire her pragmatic fashion?"
> Celestia turns to you, a little embarrassed.
> "It does her credit, to take her job so seriously. Enough of that, there is something I'd like to ask you about."
"Ask away, it's not like I have much else to do."
> "Very well. From our past conversations, I have gathered that the word clop means something different to you than the sound of hoof-falls on hard surfaces."
> Oh yes, this is going to be fun.
"You know how I said I was one of many fans of the show?"
> "Oh yes, faggots, correct?"
> So you were a little creative with what you've told her.
"Yes. Anyways, among the faggots, someone had the idea that when a pony masturbates, her hoof makes a clopping sound against her genitals."
> And there it is, the Royal Canterlot Blush.
> "Surely even they knew that is not the case..."
"Of course, but it was funny, and caught on as a general term for pornographic pony material."
> Princess Celestial fixes you with her most regal gaze.
> "I insist upon seeing this clop material. If you wish to live with my little ponies, I must know how you view them sexually."
> Sounds like shaky reasoning, but who are you to deny the princess access to porn?
"As you command. Let us go to the computer."
> You had been so happy when the scientists worked out what voltage your devices needed. 
> Even now, you get a small amount of satisfaction flipping the light switches.
> You sit down in your computer chair, and shake the mouse.
> The screensaver goes away, and you navigate to your carefully hidden clop folder.
> Celestia eyes are intently focused on the screen, and you suspect she's memorizing the folder path.
> You reach your destination.
"So, who do you want to see? The mane six, yourself, Luna, other ponies, or dragons?"
> Her eyes go wide at the implications.
> "My-myself?"
> You open your Celestia folder, scrolling through the thumbnails.
> She puts a hoof on your hand, stopping you.
> "How did they know? It's not in any of the episodes."
> What?
"How did they know about what?"
> She points to a picture of-
> You look down at her crotch.
"I'm not seeing any horsedick right now."
> She takes her hoof off your hand.
> "O-open one of the other folders. Applejack, would be good."
> Okay.
> A few clicks later, both of you are staring at some choice flank.
> Remembering what this was for, you glance down at her crotch again.
> Well what do you know, there it is.
"Looks like we are similar in how we sexualize ponies."
> Celestia nods absently, mesmerized by all the appul plot.
> You wait, but she's still looking at your porn. You're not even scrolling anymore.
> You let your hand casually fall from the mouse.
> She doesn't notice.
> You lean down and brush the side of her cock with your hand.
> She jumps back in shock.
> "Anonymous! What do you think you are doing?"
"Thought you might like a friendly handjob."
> She shakes her head.
> "You are my friend, true, but..."
"Yes?"
> "I am only interested in mares."
> Can't blame her.
"Should we call Proper Procedure in, then?"
> Celestia shakes her head again.
> "I would not abuse my authority that way."
> Then the intercom comes on.
> "I wouldn't mind, Princess."
> Oh yeah, you are under constant surveillance. 
> Celestia is frozen in indecision.
"That sounds great, Proper. Mind if I watch?"
> "... You can do more than that, if you want."
> Best day ever.

> Proper enters your house hesitantly, taking off her lab coat.
> You wave at her from the top of the stairs.
"We'll be in the bedroom."
> You return to find Celestia pacing nervously.
"You okay?"
> She stops.
> "I've never done this before."
> What.
"Not in a thousand years?"
> She sits down, and closes her eyes.
> "My... endowment is not well known, and I dare not ask this of any pony, who would feel pressured by my authority."
> You smile.
"Today's your lucky day."
> Proper pokes her nose past the door.
> "Can I come in?"
"Absolutely."
> She enters, and you are stuck by how once she isn't wearing a lab coat, she seems even more naked, despite nothing private having been covered up.
> She presents her backside to Celestia.
> "Enjoy, your majesty."
> Celestia looks at you with a panicked expression.
> She whispers,
> "Help me."
> Wow, okay.
> You lead Celestia to stand over Proper. 
> The Princess is trembling.
> You grab her cock, eliciting a quiet "Ah!"
> You guide it to Proper's waiting pussy, inserting the tip.
> The two ponies moan.
> You then push down on Celestia's ass, helping her thrust.
> She soon gets the idea, and the two mares are panting pretty heavily.
> You disrobe, and walk to Proper's face.
> Her eyes are rolled back in pleasure, and her tongue is lolling out of her mouth.
 > You look up to see Celestia in much the same condition.
> That's nice, but you want more.
> You put your dick in Proper's mouth.
> At once, she focuses on you, and starts sucking and bobbing, putting that tongue to good use.
> You groan, only to be answered by Celestia's hot breath on your face.
> Your faces are actually pretty close...
> You pull her head down and kiss her lips.
> Her eyes widen, and she pauses in mid-thrust.
> "Anonymous? I-"
> Proper groans around your dick, clearly impatient at the pause in fucking.
> Celestia resumes thrusting, and looks at you with surrender in her eyes.
> "Do as you will."
> You kiss her again, pressing your tongue against her tightly sealed lips.
> Meanwhile, Proper has been growing more vocal, sometimes even releasing your dick altogether to let out a loud cry, then sucking at it again with renewed fervor.
> Your tongue breaks the seal, and you taste Celestia's sweet mouth, battling her tongue for dominance.
> You feel Proper pushed against you as Celestia's thrusts become more vigorous.
> Celestia breaks free, crying out as she seizes Proper's hips and thrusts one last time.
> The young scientist croons around your cock as she is pumped full of royal cum.
> The mares slowly sink to the floor, exhausted. 
> Which leaves you rather uncomfortably high and dry, metaphorically speaking.
> Proper Procedure is slumped forward, her rump in the air and her pussy still leaking semen. 
> Celestia is on lying on her back, cock dripping a little onto her stomach.
> It's a tough choice, but now may be the only time you could get away with it.
> You kneel before Celestia's rump and wipe up some of her cum with your fingers.
> No reaction.
> You then poke a cum-coated finger up her anus.
> "Wha-"
> You remove the finger, then lift up her hips and press your saliva-covered dick to her rear entrance.
> Celestia's eyes go wide.
> You gently press inward, and her tight ass accepts your head grudgingly.
> Her eyes roll back, and she moans long and loud.
> Encourages, you insert another inch of shaft.
> Her anus clenches around you, and a small spurt of cum falls from her still-erect cock.
> You pull back an inch, then thrust deeper.
> "Oh, oh my."
> You lift her hips up a little higher and thrust even deeper, the cum on her stomach dripping down her chest.
> You get into a rhythm, hilting on every other thrust.
> Celestia's moans come more often, and her cock contributes more to the stream that is slowly making its way to her chin.
> You feel a set of hooves hook onto your shoulders from behind, as Proper rubs herself up against you.
> Celestia roughly jerks her own dick between her hooves, her head thrown back.
> You keep thrusting, grunting at the exertion.
> You hear a soft cry as Proper climaxes, her pussy juices dripping down your leg.
> Celestia looks up at the sound, and what she sees sends her over the edge.
> Cum fires from her cock, hitting her directly on the face, and into her panting mouth.
> You might have held out a little longer, but then Celestia swallowed her own semen.
> You let loose, shooting your jizz deep into her ass. 
> You set her hips down, and Proper Procedure dismounts.
> She then walks over and lays down on Celestia's cum spattered torso, closing her eyes in contentment.
> You eyes are drawn to her pussy, still wonderfully on display, with her legs splayed across Celestia.
> Some hardness returns to your boner, and you lay down on top of the research mare.
> You slowly insert your dick in the cum-filled vagina, and stir those juices around as the three of you fall asleep.

> In time, you are classified as safe, and would be free to live in pony society, if it wasn't for your knowledge of the future.
> Until such a time as you are not a walking spoiler, you have regular visits from the mares who watch over you in containment.
