>Psychotically Clingy Sister Edition

>Be Anon, the adopted son of two loving parents
>You meet Pinkie Pie in the University of Canterlot
>You are studying geology; she is studying study food science
>There's just something about rocks that calls to you.
>Like it's in your blood, or something.
>You hit it off almost immediately, feeling inexplicably attracted to each other
>You almost immediately start dating
>You both remark to each other that your relationship just "feels right"
>Pinkie jokingly calls you soul-mates, and you equally-jokingly agree.
>You both realize that neither of you were joking when you said that
>Over the course of a few short months, you and Pinkie Pie fall completely in love with each other
>Pinkie Pie cries when you get down on one knee in her favourite bakery and propose to her
>The ring has a smooth pink opal clutched in the setting.
>It's a perfect match her poofy hair; the hair you could spend an eternity with your face buried in it, just breathing in Pinkie's sweet scent.
>Pinkie insists on taking you down to her family's rock farm to announce to her parents and sisters that you're getting married
>With the hectic schedules of your final years in school making finding free time difficult (mixed in with the busy schedules of her family down at the rock farm), it takes another month or two before everyone can clear their schedules at the same time
>You might have... gotten a little bit ahead of yourselves and planted a baby in Pinkie a few weeks before you go down to the farm
>Pinkie didn't mind at all, and she even winked and told you in a rather seductive voice that she'd be carrying your children with her when you walked down the isle.
>By the time you leave to meet her family, Pinkie already has a small (but visible) baby-bump poking at her tummy.
>Pinkie, of course, is absolutely glowing with pride as she rubs her hand over her stomach in front of her family
>Pinkie's sisters all surround you, two out of three of them being incredibly excited about the news that they're going to be aunts; the last one just... stares at you.
>Pinkie's parents, on the other had, don't seem to share their daughter's exuberance; they're gazing at you in equal parts longing, happiness, and horror.
>"What a strange pair," you think to yourself.
>That evening, you and Pinkie are pulled aside by her parents and are brought into a quiet room in the heart of their house.
>They start up a very frank conversation with the two of you
>That's when they drop a bomb on you: you're their firstborn; you're their son.
>They say they'd recognize you anywhere. How you have your father's jawline, his nose, and his ears; but how you have your mother's eyes, her lips, and her hair.
>Pictures are dug out and distributed, and you see pictures that are almost identical to the ones your adoptive mother has of you at home.
>You feel sick.
>Pinkie pie, your fiance, lover, mother-to-be of your unborn child, and soulmate... is your flesh-and-blood sister.
>You stare, glancing between Pinkie and her (your?) parents in utter disbelief (or more like denial) as they tell you about their first trip to the city, a trip that they took you along for
>They sadly begin a tale about how the sheer number of people in Canterlot was so overwhelming, and how they had no idea what to do after you allegedly wandered off on your own
>How they spent weeks and months looking for you with whatever meager funds they could spare on the infrequent and far-apart days that they could afford to leave the rock farm and take a train to the city
>How for years, they felt so empty and dead inside without you, and how the pain and guilt got worse every time they came home from the city empty-handed
>How they hoped desperately that you were still alive out there somewhere
>How you, their own missing child at the time, had been part of the reason they had so many children in as small amount a time as they could; how they never left the rock farm unless it was absolutely necessary, and how they refused to bring any of their daughters with them when they did
>Your heart skips several long beats in a row as you stare at your wife... at your SISTER.
>Your eyes are drawn without you having to move them, down to the little bump on her belly.
>You look down just in time to watch as Pinkie's hand slides down to caress it lovingly; hesitantly.
>Cloudy Quartz and Igneous Rock Pie tell you that they love you so, so much, and how happy they are you have you back in their lives as their son
>How they will support your love for your sister with all their hearts
>Even the pregnancy
>They soon decide to leave you and Pinkie by yourselves, thinking that you two need a bit of privacy to host a rather inevitable discussion between the two of you
>What do you even say?
>What are you SUPPOSED to say?
>Do you reassure Pinkie that you still love her?
>Do you pull her into a hug and hope that, at least until tomorrow morning when the news isn't so world-shaking, that actions will speak louder than words?
>Do you-
>Your sister begins to giggle.
>You look over just in time to see her hair go ramrod-straight, which is something you've only ever seen happen twice before.
>Those two moments prompted you to honestly wonder if Pinkie should be on mood-altering medication, because that shit was SCARY.
>Seriously, you learned that day that Pinkie Pie reacts extremely poorly when something seemingly threatens her relationship with you; namely, a girl on campus trying to flirt with you in her presence.
>The poor girl will always have those scars...
>As soon as you open your mouth to say something, ANYTHING, Pinkie lets out a loud cackle and darts forward.
>She wraps her arms around your neck and pulls you into a rough kiss.
>Needing a bit of comfort, you naturally return it.
>This, unfortunately, prompts Pinkie to try and crawl into your lap; you've been with her long enough to recognize innocent lap-sitting and l-lewd lap-sitting, and this sure as hell isn't just your fiance deciding that she wants a cuddle while the two of you study together at her dorm.
>This is a "fuck me until neither of us can walk straight, then fuck me until we somehow loop back around to being able to walk again" lap-sit.
>You are kinda not really in the mood, what with the whole "you dated, became engaged to, and then knocked up your sister" thing and try to pull away, but Pinkie aggressively follows your movements.
"Pinkie!" you yelp as she grabs your dick through your pants, "Wait! For fuck's sake, not NOW!"
>"Yes, now!" she gasps, pulling away from a patented Pinkie Pie kiss; aka a sloppy, taste-her-for-three-days kiss, and then nuzzles your cheek, "I NEED this!"
>You try to push the desperately cock-hungry girl away again (your adopted father always DID think you were gay), but your fiance/sister will not be deterred.
>"You heard mom and dad, right?"
>Fuck
>She isn't even bothering to call them "MY mom and dad", like she usually does.
>"You were lost, but then you came back. I found you."
>She giggles again, but now it sounds slightly deranged.
>"I always said we were soulmates, didn't I? This is fate! We were meant to be! We were separated just so that we could meet later in life and become lovers; husband and wife!"
>Oh, jeez.
>Pinkie sure isn't dealing with this very well.
>Instead of pushing the issue away, she's grabbing it with both hands and is steadfast refusing to let go for any reason.
>So instead of being grossed out or questioning your love for each other and what the future will hold for you, Pinkie's decided to embrace what happened and has apparently decided that this is the best thing ever.
>God dammit, you wished you had studied psychology instead of geology.
>"Do you know what this means, Anon?"
>Pinkie grin widely as she holds your face with both hands.
>"This means we're never going to be apart ever again! We're lovers, and we're siblings; we're meant for each other!"
>She lets out a very Pinkie-like squeal (which is incredibly comforting in a time like this) and rubs her nose against yours in an eskimo kiss.
>Eye twitching slightly, she leans backwards and stands up, grabbing your hands and pulling you to your feet.
>"C'mon, Nonny," she purrs, "Let's go see what my old bedroom looks like. 'Cause you're not going anywhere now that we've all got you back, and tonight will make good practice."
>She leans in and gives you the most smoldering look you've ever seen from her.
>"Because Pies always have large families... big brother."
>wew lad
>Maybe fucking your pregnant sister is exactly what you need to get over this whole "you got your long-lost sister pregnant"
>You'll deal with this more in the morning; preferably after you pass out from fucking Pinkie Pie too hard, too many times.
>Because fuck it, at this point.

follow up to Limestone being sick of this shit:

>Of course.
>Of fucking course.
>You all knew that Pinkie would be the first to get some action.
>For fuck's sake, you and the rest of your sisters are still virgins because mom and dad never let you leave the rock farm.
>You mean, you guess you know why now; the last time they let one of their children leave, they fucking LOST him like luggage at an airport, or a book on a park bench.
>Jesus, you still don't know how Pinkie managed to convince mom and dad to let her go out to attend university, especially since home-schooling the four of you had worked so well and had gotten you all up to the level of a high school graduate.
>And of course, of FUCKING course, Pinkie manages to find your long-lost brother that you have apparently always had.
>And of course he's gotten her pregnant.
>Because you live alone with your family on a quarry and you've never even SEEN a man who isn't your dad, and you had hoped that maybe Pinkie Pie would be willing to share.
>You mostly thought this because you're desperate and horny, not because you actually thought that Pinkie Pie would be willing to share.
>But he's not just any guy, he's your BROTHER.
>The only other man to ever visit your farm, and he's off-limits by ways of A) being Pinkie's fiance, and B) being your BROTHER.
>Fuck your life.
>Fuck this farm.
>And FUCK how sore your arm is because you spent all night laying wide-awake, masturbating as you listened to Pinkie Pie fuck your brother in the room next to yours.

>Meanwhile, in the adjacent room, Anon and Pinkie Pie lay in a sweaty heap in the middle of her comically-small twin-sized bed.
>They're breathing heavily as they try to get as much oxygen out of the muggy air as possible.
>If there were a window nearby, it would be fogged up right now; it was UNCOMFORTABLY warm.
>Anon's cock, having just delivered a fresh batch of baby-batter into his sister's hungry snatch, twitches violently with no warning
>"Nonny!" squeaks Pinkie Pie, "Oh, you naughty boy! Is cumming inside of your sister just three times not enough?"
>If Anon were a stronger man, he would have responded with something sultry and appropriately seductive.
>However, he is just a young man who came three times in the last hour, and his dick is as sore as it was way back during the first week he discovered masturbation when he was a young teen.
>"N-No," he groans, "I mean... yes?"
>It's hard to think immediately post-orgasm, to be fair.
>"It's just... I suddenly got the oddest feeling that someone out there, somewhere in the world, was talking dirty while using geology terms."
>Pinkie just snickers, having a decent idea (read: perfectly accurate conclusion) of who this individual just might be.
>"Oh, Anon," she purrs, gliding a finger along the edge of his jaw, "I just hope you're ready for me to ROCK your world."
>Anon releases a raspy moan that sounded like a ghost trying to escape his chest as he twitched inside of his sister once more.
>It was always easy for Pinkie to make Anon hard.
>Like a rock.
