>Three days
>It had been three, long, agonizing days since the...incident
>You didn't want to call it anything other than that.  An incident
>Though what you wanted to call it and what you knew it was were completely different
>You writhe around on your bed, wrenching the covers over your head trying to process it all
>Rarity...your lover, your sweet, succulent, exotic treat.  The mare who held your world in her hooves.  Who made both your heart and your loins long for her presence
>You groan
>Why couldn't you think about her like that anymore?!
>True, your attraction to Rarity was far more than just sexual
>You would do anything for her.  Give her anything her heart desired.  Love her until you both were far too old to do anything sex related that didn't require pharmaceuticals and/or a trip to the emergency room for a broken hip
>But now...now whenever you tried to think about her sexually, a different mare hijacks your thoughts
>Well, not really a mare actually...not yet, anyway
"Fucking Sweetie Belle!"
>Your outburst is followed by you throwing the covers off of your head and stomping towards your kitchen
>As you grab a beer from the fridge you sigh
>You can't be mad at her, it's not her fault
>Not her fault she handled your cock and balls with such a deft mastery...not her fault her young, innocent little face looked so sweet while she gorged herself on your meat...
>And certainly not her fault that when you saw her sitting there, covered in your cum, bashfully confessing how she had creamed herself while sucking you off, you just wanted to bend her over and fuck her little brains ou-
>You slam the beer on the table, causing it to spill a little
>Stop.  Fucking.  Thinking that!
>You groan in self pity as you feel your dick strain against the inside of your pants
>Why?  Why did you let Rarity talk you into "helping" Sweetie Belle "learn a skill for mares"?
>Well, good job, big sis!  Looks like little Sweetie knows what she's doing now!
>You slide into a kitchen chair and slump forward on the table
>Dammit, man, stop feeling so sorry for yourself.  Think about what this is doing to Rarity
>Rarity...she had come by several times during your three day self-imposed house arrest
>She had looked concerned, asked why you didn't want to spend time with her
>You had given her the usual bullshit about work, or feeling under the weather, but those excuses were beginning to wear thin
>Yesterday, she had come right out and asked you if you were angry/grossed out at her about, well, the incident
>You had told her the honest truth.  That you were not grossed out...you just made sure not to tell her why...
>You remember her exact words
>"Anonymous, I don't want to drive you away!  I love you more than anything in the world!  Please tell me what's really wrong!"
>But you couldn't.  You just couldn't tell her that...despite your undying love for her, despite the fact that she meant so much to you...
>You drain your beer and toss the bottle aside, slumping your head back on the table
>You were in absolute, unquenchable lust with her sister.  And that lust was making Rarity a damn background character in your thoughts
>Admitting it to yourself almost made you want to vomit.  Why did you have to be such a sick fuck?
>Again with the self pity...would you just man up already?!
>Yes...man up...
>You know what you have to do
>Practically sprinting to your bedroom, you throw on a clean pair of pants and a t-shirt, before donning your coat
>Yeah, you know must be done all right.  You were going to man up for your lady
>You were going to march over to her house, kick in her door, scoop her up in your arms and take that mare to bed
>You needed to show her that you still loved her, that you still found her undeniably sexy, and wanted never to be apart from her loving embrace ever again
>Much as she said she loved it when you were more gentle and willing to woo her into bed...you knew she loved it when you were unapologetically manly as well
>You finish tying your shoes and stroll out of your house, determination in every step
>It's a chilly, autumn weekend and not many p0nies are out and about
>Good, you needed to be alone to think
>Unfortunately, your thinking slows your footsteps slightly.  Worry and doubt begin to creep into your mind
>What if she asks you about the incident?  Oh god, what if Sweetie Belle is there?  That could be extremely awkward
>What if you couldn't get it up for her?  Did you really want to resort to thinking about her sister in order to plow her?  Again?
>You shudder and pull your jacket tighter about you
>You can't think these things, Anon.  You knew what you signed on for when you two started dating...a commitment, trust, honesty
>Besides, you two were stronger than this.  You had had your arguments and rough patches before and you had both survived them unscathed
>Despite her pretentious nature, Rarity was a very understanding girl
>Understanding...you can't help but wonder just how understanding she was...
>Maybe you could let her see that Sweetie Belle was ready for more than just blowjobs.  That perhaps she could join you two
>Now wouldn't THAT be something...a sister + sister + boyfriend threesome.  Yeah, you could definitely go for something like that.  That was "dear Penthouse forum" stuff
>You awkwardly try to shift your jacket lower to conceal the oncoming hard-on you're experiencing at the thought of nailing them both
>But like most of the letters in Penthouse forum, you knew that such a notion was probably just self indulgent fantasy
>Rarity was remarkably possessive of you
>Not in a clingy or insecure way, thankfully, but possessive nonetheless
>Whenever you two were out together and she had even an inkling that another mare was eyeing you, she would often nudge in close or give you a kiss, establishing that you were hers, and only hers
>Seems being the "element of generosity" doesn't extend to her sexuality
>You chuckle to yourself as you remember one day at the market when she had griped to you
>"Honestly, Anonymous, can you believe the audacity of these mares?  Here I am, clearly standing right next you, and they're all just waiting for a chance to get their grubby hooves all over you!"
>You had sighed, exasperated
"For the last time, Rarity, that's all in your head.  No mare is eyeing me up, and they're certainly not trying to get me away from you"
>She had just huffed indignantly
>You had then crouched down to her height to look her in the eyes
"I'm not as much of a catch as you think I am, you know" you had stated, smiling at her
>She hadn't looked convinced, but had started to smile back
>"Are you saying I have poor taste, Anonymous?"
>You had run a hand through her mane, causing her to giggle
"What I'm saying is that their eyes aren't the issue.  Mine are.  And they belong only to you"
>She had sighed contentedly and leaned forward, pecking you on the lips
>"Sometimes I wish I was larger, Anon.  Like the horses you mentioned from your world.  That way, I could don a stylish saddle and carry you around town.  I would bear you proudly with my head held high, eliminating all doubt of who you were with"
"Rarity, I'm shocked!"
>You had lifted her hoof to your face and kissed it, causing her to blush
>"Oh, my..."
"To think that I would relegate you to a mere beast of burden.  You are far more than that to me, my dear"
>She had swooned
>"Oh, Anon...how could I be so lucky as to have you?"
"Because you deserve it, my sweet.  And I think you also deserve this..."
>With that, you had scooped her up and quickly plopped her down to sit on your shoulders
"There!  Now there's no more doubt who I choose to be with, and you get your 'carrying your partner around' fantasy...kinda"
>"A-Anon!  My, how bold!"
"Oh, you know you like it"
>"Hmmm, I suppose you have me there..."
>She had wrapped her forelegs around your head and rested her chin on your dome, not caring about the stares and "d'aawwws" of the nearby p0nies
>"I apologize for being so possessive, my love.  It's just that...I sometimes wonder if there is a p0ny out there better suited for you...one who could make you happier than I can...and if I ever encountered her...goodness, I don't know what I would do..."
>You had grunted at that
"I wish you wouldn't think such things, Rare.  You know you're the only one for me"
>Ah, those had been the days
>When things were less complicated and Rarity truly was the only one you could think about that way...when her sister was just a mildly annoying kid and not...
>You shudder as the dark thoughts return
>Got to get to Rarity's, got to make this right
>As you pass Twilight's library, you decide to throw away the idea of proposing a cathartic three way between you all for two reasons
>Number 1: Rarity's slight paranoia at not being the primary focus of your affections obliterates that possibility
>Number 2: Sweetie Belle is a goddamn child, and you're a sick bastard for even considering fucking her in a three way
>As you continue your short trek, your thoughts become quieter, resting for a while and letting you mentally prepare for what you have to do
>What you WANT to do, what you WANT to do!  That's what you meant!
>You want to storm into her house and scoop her up into your arms.  You want to trail your fingers through her white coat.  You want to look deeply into those soft, warm, green eyes...
>Blue!!  Rarity's eyes are blue!
>The urgency of what feels to be your waning sanity causes you to start running towards Rarity's house
>Finally you arrive, albeit out of breath
>Really should've accepted all those invitations from Dash to go workout together
>You place your hands on your head and pace around the stoop for a minute or two, regaining your breath and your mind
>Okay, Anon, no time like the present
>Time to show this little gal what a big man with a big, swinging dick can do
>Fiercely, you grab the door handle and turn
>Locked...well that kind of ruins your momentum
>Fine.  Guess you're going to knock...but in a manly way
>You pound hard on the door with a closed fist
"Rarity!  It's Anon!  Open up!"
>Your abuse of her door is instantly rewarded when you hear the light clickety-clack of fast-approaching hoof steps just inside
>Good...it sounded like she was excited to see you
>You do a last minute check of your appearance to make sure you were at least somewhat presentable for your lady
>Jeans, tennis shoes, a plain shirt and a slightly dusty jacket
>Well, you weren't going to be winning any fashion shows but at least you were showered and sha-
>You groan as you run your hand over your face
>You hadn't shaved...three days worth of beard stubble lined your mug
>Oh, well.  You were going for the manly man approach here.  Maybe she wouldn't mind
>As you hear the lock click and the door knob beginning to turn, you straighten yourself up, placing your hands behind your back
>Yeah, check out this proper gentleman motherfucker right here
>The door opens and you prepare to bolt forward...
>Only to stop, horrified, in your tracks
>"Hey, Anon!"
>Oh, no...goddamnit, not now...
>Instead of seeing the love of your life opening the door for you...she's there...
>Sweetie Belle stands, staring up at you and smiling her biggest, sweetest grin
>She looks so innocent, so adorable, so young and lithe and...
>"Rarity's not here right now.  She went to Canterlot for the day, I think"
>Oh, fuck.  How could you have forgotten?
>Rarity told you last time she came to visit you that she was going to be gone talking to a potential client today
>"And I get to take care of the house, all by myself!"
>Her voice squeaks and she jumps into the air, wiggling her hooves under her
"Ha...yeah...that's....great, Sweetie Belle.  Uh, so since Rarity's not here, I'll get out of your hair.  You know, let you hold the fort.  Sorry to bother you"
>You move to leave, but she stops you
>"Wait!  You've got to see something!  I made it myself!"
>She dashes back inside the house before turning to face you
>"Come on, Anon!  It'll only take a second!"
>You feel frozen in place, gawking at her
>How is she...how is she not totally weirded out by you right now?
>Three days ago, she had sucked your dick...so, so well...
>Dammit, what were you saying?
>Oh, right.  Three days ago, you two had had a "moment" and now all she could do was just smile at you like before?  Like nothing had happened?
>"Well, don't you want to see it?  Come on, Anon!"
>You feel your feet beginning to move forward
>No!  God, man, what are you doing?  You can't go in there!  Not with her!
>You still can't shake those horrible thoughts
>Seeing her now, you realize that your body is, and is going to be, reacting quite favorably to hers
>To that sweet little face, to those tender young hooves, to that tight, plump little behind that she seemed to wiggle at you as she walked...
>Click
>What was that?
>To your horror, you realize that you've already walked inside and shut the door behind you
>Dammit body!  You don't want to possibly end up a filly fondler!  You need to leave!  Right!  Now!
>Sweetie Belle has trotted off, out of your line of sight
>"Oh, good!  It looks like they're finally ready"
"W-What's ready, S-Sweetie Belle?"
>She peeps her head around the corner, looking a little annoyed that you were still standing by the door
>"I can't show you unless you come here!"
>She raises a brow at you
>"Are you okay, Anon?"
>You must look quite the sight
>Frozen in place, brow sweating, petrified, unblinking gaze
"U-Uhhh...I'm fine, Sweetie Belle!  I'll...I'll just be there in a second.  Got to take my shoes off, heh..."
>Satisfied with your answer, you sit down in a chair by the door and begin to undo the laces
>Your shoes and jacket are already off before you realize what you're doing
>Fuck, man!  You need to be leaving, not making yourself at home!  Leave now, while she's...
>You suddenly smell smoke and you groan
>...in the kitchen
>It was no secret that Sweetie Belle was a shit cook
>Anyone who manages to burn juice needs to wear a sign that says "please keep me away from any object even resembling a stove"
>Well, shit.  Now you can't leave just yet
>If you leave now, Sweetie Belle might burn down the whole house with her terrible cooking
>You sigh and walk over to the kitchen
>Okay, just going to fix her mess, dump whatever abomination she's concocted and...
"Oh, my god!"
>The kitchen looks like both the cooking supplies and baked goods aisles at Walmart just took a big shit everywhere
>Sweetie Belle is rifling through a drawer, throwing its unwanted contents all over the place
>"I know it's a little messy, Anon, but don't worry I'll clean it all- there they are!"
>Sweetie Belle retrieves a pair of oven mitts and dons them before opening up the oven
>A thick cloud of smoke bellows forth and you cough profusely before running over and shutting off the oven
>Sweetie reaches in and retrieves a baking sheet before letting it clatter to the floor
>"Oops...heh heh..."
>You finish coughing as you open a window to the let the putrid cloud roll out
>When you return to Sweetie Belle, she stands proudly over her horrific creation
>A baking sheet that holds what appears to be an assortment of charcoal briquettes...
>"Well, Anon?  You want a cookie?"
>Oh, cookies...that's what they were supposed to be
"Uhhhh, you first"
>Naively, she scoops one up and pops the whole thing in her mouth...
>Before spewing it all out all over the floor
>"Awwww, that's the fourth batch today..."
>She sits down hard and pushes the sheet away from her
>You laugh
"Maybe you should just stick to blow jobs, kid"
>Your hand flies to your face and claps over your mouth
>Oh, shit, man, why did you say that?!
>You attempt to speak
"Sweetie, I'm so sorry...I didn't mean..."
>"You really think they look that bad?"
>She looks like her heart is about to break
>Thank heavens.  It looks like she cares more about the cookies than what you just said
"N-No, Sweetie...they're not that bad...just a little...crunchy is all..."
>She muses for a second
>"If they're not that bad..."
>She turns up to look at you
>"Does that mean my blow jobs are really just that good?"
>You need to leave
>Thankfully, your body listens to reason this time and you begin walking toward the door
"Sorry, Sweetie, I gotta go"
>"Wait!  Anon!"
"Not now, Sweetie, I have to leave"
>"But I've been meaning to ask you about that!"
>She follows after you quickly
"There's nothing to ask about, Sweetie Belle"
>"B-But...I want to know if I did a good job..."
>Her voice sounds pleading and pathetic
>"If I pleased you...like a good mare should..."
>You stop walking and sigh
>Turning around, you see Sweetie Belle standing a few feet behind you, eyes looking downward, dejected
"Sweetie Belle, you don't need to worry about pleasing me, that's your sister's job"
>She flips her head up quickly to look at you
>"But I DO need to worry about that!  Rarity said I need to be able to please my future stallion!  And...and I want to know that I can do that"
>She takes a few steps forward
>"Did I please you, Anon?  Was it good for you?"
>She looks away, nervously
>"It was good for me..."
>Have to choose your words carefully here
"Sweetie...you did a great job...it felt really good for me and I enjoyed it...a lot"
>Far more than she can ever know...
>Her expression lights up.  She looks so cute and ecstatic
>"Really?!  Was I as good as my sister?"
"Heh, as good?  You were better!"
>Hand meets mouth again, violently
>Why?!  Why are you doing this?!
>"B-Better?  You really think so?"
"Uhhhh, sure why not?  Gotta go!" you force out as you turn back towards the exit
>"Wait!"
>She bolts ahead of you and slams her body against the door
>She stands now on her back legs, bracing her forelegs against the door, trying to bar your departure
>She stares intently at you, eyes widening...
>Oh no, you knew that look
>That look had haunted your thoughts for three days
>It was a look of young, hormonal lust
>Not wanting to meet those eyes, your gaze trails downward
>Down over her soft, warm belly...down to her...
>Oh, god...her tender, moist vagina
>Standing like she is, she's able to expose it to you
>It's dripping a little and you can see her clit beginning to wink in and out
"S-S-Sweetie B-Belle, I have to go now..."
>"But, Anon, I...I..."
>She groans and shuts her eyes in embarrassment
>"I don't think I learned everything I should...and I think I need, uhmmm, more practice..."
>Sweetie Belle looks up at you, doing her best to give you the puppy dog eyes
>"Anon...I can't stop thinking about what we did...I want to do it again...but not to some stupid colt from my class...I want you, Anon.  I want you in my mouth again..."
>She looks at your crotch
>"And I think you want me too"
>Dear god, your dick looks ready to tear a hole in your jeans in its current state
>You take a few steps back
"No, Sweetie Belle!  We can't!  That was just one time!"
>You cover your face and groan
"And I'm not supposed to want that!"
>"Why not?  Rarity said the way I felt towards your body was natural...so the way you feel towards me must be natural too!"
>She lets herself fall off the door on to all fours and begins advancing on you
"No!  No, it's not natural!  Sweetie Belle, you're a little filly, and I'm an adult!  I-I need to be with mares my own age!"
>You back up a few steps from her
>Sweetie's expression becomes indignant
>"I'm not a little filly anymore, Anon!  I'm a young mare now!  Could a 'little filly' suck you off like I did?  Could a 'little filly' please you better than my sister could?!"
>Your back peddling stops abruptly as you bump into the wall behind you
>Sweetie Belle seizes the opportunity and pounces forward
>She rises up on her back legs and places her front hooves on your thighs
>Her head is now at crotch level
>She gazes at your boner wistfully before looking up into your eyes
>"Please, Anon...we shouldn't be embarrassed by this...you're a stallion...and I'm a mare...and we both want each other.  What's so bad about that?"
>You can't answer her
>You feel lost in her sweet, soft eyes
>While Rarity's sapphire eyes seemed to hold you with their gaze, Sweetie Belle's emerald globes seemed to coax you instead...inviting rather than demanding
"Sweetie Belle...I'm with Rarity...you know that!"
>She just grins
>"Anon, you silly goose.  I wouldn't want to take you away from my sister...I just want to practice with you.  Besides..."
>She eyes your crotch and licks her moist lips
>"She didn't seem to have a problem with me doing this before..."
>She trails a hoof across your erection, causing it to twitch, yearning for her tender touch
"B-But she's not here!"
>Sweetie Belle turns to you again
>"Not until tomorrow, no...which means we have all night, Anon..."
>Suddenly she dismounts and begins to walk towards the staircase
>As your eyes follow her slow, sultry movements, you notice that she flicks her tail to the side, exposing her dribbling young fillyhood
>"Come on, Anon...if I'm really that good at sucking your big, hard, throbbing dick...who knows what else I can do..."
>You can't take this anymore
>Hearing such a sweet, squeaky voice talk dirty to you sends you over the edge
>As if on instinct, you step over to her and pick her up in your arms
>Without missing a beat, Sweetie Belle turns to face you and mashes her lips to yours
>Your surprise is cut short by the feeling of her tongue on yours
>As it turns out, Sweetie's tongue wasn't just good for massaging your dick
>The warm, velvety muscle playfully bats against yours
>She kisses with all the fervor of youth, without being so sloppy it's uncomfortable
>You reach a hand behind her head and pull her in deeper
>She moans appreciatively into your mouth
>You can almost feel the structural integrity of your pants failing you
>For another minute, you two share a passionate, fervent kiss before she breaks from your still gaping mouth
>Sweetie speaks to you in a low, seductive tone
>"Do I kiss better than my sister too?"
"Yes..."
>You breathlessly utter the startling truth
>She giggles
>"Then take me upstairs, big boy..."
>You pull her into another deep kiss as you alight the stairs, this one more passionate than the last
>Your reservations about this were long gone.  Pure, animal lust was driving you now
>As you approach her room, Sweetie Belle 'mmphs!' loudly and pulls away from your lips
>"No, Anon!  I want to do it in her room!"
"Oh...of course..."
>Your body feels as if it was on autopilot as you turn and head into Rarity's room
>When you approach the bed, you set her down on the comforter and take a seat on the edge, like before
>"No, Anon...I want you to lay down.  Put your head on the pillow...that's right..."
>You comply with Sweetie's request and stretch yourself out on the bed
>As soon as you're situated to Sweetie Belle's liking, she pounces on your crotch, trying to undo the button and zipper with her clunky hooves
>"Um...heh...I think I need some help with this part..."
>You reach down and undo your fly before shifting your pants and boxers off
>When the garments pull across your adamantine dick, you experience a bit of pain, followed quickly by release as your cock springs upward, finally released from its cloth prison
>Sweetie Belle blushes furiously at the sight
>"Wow...I make you really hard, don't I?"
>She has no idea
>Sweetie turns to you, smiling
>"You have a beautiful cock, Anon..."
>Hearing more dirty words come from her squeaky little voice makes you even more eager
"Y-You're beautiful too..."
>Her blush intensifies
>"Thank you, lover"
>Without allowing you to process that last exchange, she moves in towards your dick and takes a deep breath
>"Okay, step one...give him a few licks to get him interested"
>You grunt
"Sweetie...doesn't that already look 'interested' to you?"
>She rubs her chin with a hoof
>"Yeah...guess I don't need to do that step...you know what?  I don't think we need to do any of Rarity's stupid steps.  I'm the expert cocksucker here, not her!  And I want to do it like this!"
>Sweetie Belle suddenly jumps on top of your torso, facing away from you
>Her still dripping pussy is almost in reach of your face
>"Ready Anon?  Here it comes..."
>No, you were not ready
>Nothing could have made you ready for the sudden feeling of warm, wet filly tongue on your dick
>Your body spasms and both of your hands grasp the comforter as you feel her wrap that expertly controlled muscle around your shaft
>She goes in rough, licking hard around the circumference of your cock
>You can see her head move from side to side as she switches her ministrations from one side of your cock to the other
>While performing this maneuver, she moves from the base of your dick to the head and, without warning, plunges the helmeted warrior into her mouth
"Ohhhhh, shhhhhiiiit...you...you don't waste any time...do you, Sweetie Belle?"
>She suddenly releases your cock head and turns back towards you
>"Anon...don't talk.  Unless you're going to call me a slut..."
"What?"
>"You heard me!"
>She pants loudly and her winking begins to increase its rapidity
>"I want you to call me a slut!  A whore!  A filthy, filthy little p0ny!"
>You growl
"Not until you get back to sucking my fat cock, you little cum dumpster"
>Hmm, that might have been a bit excessive...
>Sweetie doesn't seem to think so, however, as you see her vagina begin to wink harder now and dribble a copious amount of fluid onto your chest
>She attacks your cock with more ferocity than before
>Sweetie Belle expertly takes you all the way down her throat in one go, causing you to gasp
"Oh...oh, shit...oh, you filthy little cocksucker..."
>Your insults are rewarded with her pulling back and slamming down hard on your dick again
"Yeah, you're just a slut aren't you?  You can't get enough of that diiiiii...mmmph"
>Sweetie Belle reaches around your cock and begins to massage your balls like before...except this time, she does it with force
>Not enough to cause you pain, but enough to turn your speech into grunts of pleasure
>Sweetie continues roughing your dick's comfy bean bag chair while taking your length down her warm throat, stopping occasionally to flick the head with her tongue
>There was no longer any doubt in your mind
>Nop0ny...nop0ny could suck a dick like little Sweetie Belle could
>All too soon, you feel yourself reaching your limit
>For the second time in a week, you were about to blow your load down a filly's eager throat
>But this time...this time you just couldn't care anymore
>It felt so goddamn good
>You look up to see Sweetie Belle's dripping cunt
>A thought occurs to you
>Within moments of T-minus zero, you turn the two keys and halt the missile launch
"S-Sweetie Belle...wait...stop..."
>She immediately complies
>"What's wrong, Anon?  I thought I was doing it right..."
>Her tone expresses her disappointment
"No...no you're doing...oh, my god, you're doing so well"
>You catch your breath and continue
"I just wanted to try something else..."
>"What did you want to tr-YIP!!"
>Sweetie squeals as you dig a finger into her pussy, rubbing just inside her walls
>"Oh...oh, okay...I understand.  B-But Anon, I don't know if I'm ready..."
>Her vagina clamps down on your digit and you pull it back out with a forceful POP
>You reach down towards her face, holding the slime covered finger up to her
"Oh, I think you're ready, Sweetie"
>She turns back to look at you and smirks
>Without prompting, she practically inhales your finger and sucks slowly up towards the tip, fixing you with a half-lidded, seductive gaze all the while
"Dirty, dirty girl...."
>Her mouth reaches the end of your finger and she kisses the tip
>"Only for you, Anon"
>You reach up and grab her tiny body before turning her around, positioning her entrance right above your member
>"Wait!"
>Sweetie Belle's new found confidence appears a little shaken, as she stares at you with worried eyes
>"Does it...does it hurt?"
>You laugh
"How should I know?  I'm not a mare"
>"Anon..."
>Sigh
"I'm told it hurts a little the first time.  That's why we're going to take this slow, okay?"
>That seems to restore her eagerness and she smiles at you
>"Okay, Anon"
>You begin to lower her on to your waiting dick, your cock head touches her lips, parting them slowly
>The contact is enough to make Sweetie Belle shut her eyes and squirm with pleasure
>"Oh...oh, please, Anon...shove it in me!"
>You grin
"Beg for it"
>Her eyes fly open with surprise, but to her credit, she really knows how to roll with the punches
>"Oh!  Oh, please rut me, Anon!  I need it!  I need your big, beautiful cock in my pussy!  Please, don't make me wait!"
>Rarity never begged you like that...
>Not looking to injure the young mare, you slowly lower her farther onto your rod, letting your cock head part her tender, delicate folds
>As you sink in deeper, you can see her groaning and writhing in your grasp
"Let me know if it's too much"
>"It's...it's fine, Anon...keep going"
>You oblige and pull the little cock sock farther down your dick, spearing her on your manhood
>When you're no more than an inch or two in, you feel some resistance
>Suddenly the resistance gives and Sweetie Belle screams
>A mixture of pungent juices dribble down the sides of your dick
>See ya later, hymen!  Still, it shouldn't have been that painful...
"Sweetie?  You alright?"
>She takes a second to catch her breath and speaks shakily
>"S-Silly Anon...don't you know...when you've made a mare cum?"
"Well that was fast" you chuckle
"Don't tell me that's all you've got"
>She narrows her gaze at you
>"Let go of me, Anon"
"Now wait, Sweetie, you might-"
>"Let me go!"
>You comply and she grunts as the full weight of her body now rests on your cock
>Slowly, her tight hole begins to give way and she slides ever so slowly down your dick
>"Ohhhhhh!!"
>She's not the only one experiencing pleasure/pain
>Her snatch feels like it's on fire to you
>And it's so unbelievably tight
>As if you were trying to cram a kielbasa into a keyhole, you feel like you aren't going to fit
>You throw your head back, grunting and straining, as your dick is enveloped in the warmest, juiciest, wettest place imaginable
>"Th-There!"
>You look up and your mouth falls open
>Sweetie Belle, little filly that she is, is sitting on your cock, all the way down to the hilt
>You can't believe that much meat fits inside such a small package
>You swear you can even see the head of your own dick, making a bulge in her stomach
>Sweetie Belle wears a satisfied smile, enjoying the sensation of being filled to the brim
>"You were right, Anon...this WAS a good idea"
"You know, you never stop impressing me"
>She licks her lips and bends forward, placing her front hooves on your abdomen and bracing her back legs on either side of you
>"I'm just getting started, lover"
>Sweetie Belle pushes off her back legs, rocketing her upwards before pushing on her forelegs to pull you almost all the way out of her
>You both groan in ecstasy while Sweetie's rear hangs in the air, higher than her head
>You can feel that the head of your dick is still inside of her
>As quick as she performs this gymnastic maneuver, she releases the tension in her legs and slams her hindquarters back down onto your member, taking your whole length back inside her instantly
"Oh, god!"
>Sweetie shudders from the pleasure of suddenly being filled again and braces herself
"Sweetie...Sweetie Bellllllllle..."
>Your last syllable becomes drawn out as she pushes back off both the bed and your body to draw you out of her before once again slamming her rear back down on your dick
>"Mmmmffff...oh..."
>You can tell she's cum a second time, but that doesn't stop her
>Again and again she launches her small body up before slamming herself back down on your dick, taking an organ nearly half her size in and out of her body
>You lose track of time, of place as her lithe little frame pounds itself mercilessly on your dick
>Soon, you're back at your limit
"Sw...Sweetie...I'm...I'm gonna..."
>"D-Do it, Anon...cum in me!  Cum inside me!"
>Your dick twinges for a final time and you release yourself into her womb
>Wave after wave of cum spews forth to fill her guts
>Though her body clamps down, trying desperately to milk every last drop from you, some of your seed inevitably spills out from her vagina and down the sides of your dick
>When the best orgasm of your life finally subsides, you both just lay there, panting like animals
>Sweetie Belle stretches herself out, across your stomach, still looking up at you
>"So, Anon...was that...was that better than Rarity?"
"Sweetie...you have no idea how much better that was"
>"I'll say"
>Oh, fuck no
>That voice makes your blood run cold
>Praying to whatever deity might be listening that what you heard was only a guilt-induced hallucination, you turn your head in the direction of the sound
>Sadly, you weren't hallucinating
>You see Rarity, standing in the doorway of the room, a shocked...no, catatonic expression plastered on her face, staring at the two of you
>Her many travel bags lay scattered around her as well as some gift bags
>There's even a filly-sized "I (heart) Canterlot" t-shirt among them
"Rarity!  This isn't..."
>You lying bastard, this is EXACTLY what it looks like!
>You pull Sweetie Bitch off of your now limp dick and shoot out of the bed, over to Rarity's side
"Oh, honey, I'm so, so sorry!  I don't know what came over me!  I just...I..."
>Her face follows you but remains in its dispassionate, wide-eyed state
>"Rarity!  You...you weren't supposed to be back-"
>Sweetie Belle's sister cuts her off, still staring at you
>"Deal went through.  Faster than I thought.  Took an early train back"
>Her eye twitches
>"Saw everything...watched..."
>You collapse to your knees before her
>"Oh, god...oh, Rarity, I'm sorry.  W-We were just practicing like before, she means nothing to me!"
>"Hey!"
>Sweetie Belle interjects
>"You said I was better than her at this!  You said-"
>You whip around in anger and bear your teeth at the little temptress
"Shut UP, Sweetie Belle!"
>"No, Anon.  No, she's right..."
>Rarity turns her gaze slowly to Sweetie Belle
>"She...she certainly IS better at this than I could ever hope to be..."
"Rarity...what the f-"
>To your surprise, Rarity launches forward at you, planting a kiss on your lips
>She falls back
>"And...and for some reason..."
>She smiles at you
>"I have NEVER been more turned on in my life!"
>Through the horror of the moment you see it now
>Rarity's blushing features, her tail raised slightly, the faint dripping sound of mare juice on the floor of her bedroom
>"Watching you two...watching Sweetie Belle's mastery of sexual prowess...and watching your enjoyment..."
>She looks back at her flank
>"Goodness, I think I'm about to make a mess..."
>You sit for a moment in stunned silence
"Rare...you can't be serious...I cheated on you!  I'm scum!  I betrayed your trust!"
>Rarity shakes her head
>"No, Anonymous...I wanted Sweetie Belle to learn to please a stallion.  It turns out I got my wish.  Even to the point where she has easily surpassed me"
>She rubs her head with a hoof, trying to collect her thoughts
>"Do you remember that day in the market, Anon?  Do you remember when I said I wouldn't know what I would do if I ever encountered a mare who could make you happier than I could?  Well, I really meant it.  I didn't know what I would do...but as it turns out..."
>She faces you again, smiling
>"It turned me on like nothing ever has!"
"B-But Rarity!  YOU make me happy!  YOU are the love of my life, not her!"
>"I know, I know, Anonymous, and I love you too...but Sweetie Belle...it has become quite apparent to me that she can please you in ways I simply cannot"
>Before you can reply, you hear the clacking of hooves on the ground
>Sweetie Belle strolls up to Rarity
>"So you admit it, then?  I'm better at pleasing a stallion than you are?"
>Rarity smiles sheepishly
>"Yes, Sweetie Belle, you are far better in the bedroom than I could ever hope to be"
>"Hmmm"
>Sweetie rubs her chin again
>"And it excites you to watch me work over your boyfriend"
>"Like nothing you can imagine..."
>Sweetie Belle looks at you, then her sister and grins
>"So it's almost like I'M the big sister here, and YOU'RE the little sister"
>Where is she going with this?
>"Well...I suppose one could see it that way..."
>"And it's like I'm the one who should be teaching you how to be a mare and properly please a stallion"
>Rarity blushes
>"Well...I..."
>Sweetie's tone suddenly takes an edge to it
>"Oh...does that excite you, LITTLE sister?  Does it make you horny to know that I'm far more capable of being a proper mare in bed than you are?  That you're just a silly little filly who needs to be coddled and taken care of?"
>Rarity's tail begins to lift and her blush darkens
>"Y-Yes...big sister..."
>Sweetie Belle places a hoof under Rarity's chin and sneers
>"That's what I thought, little sister"
"Okay, time out...what in the blueberry fuck is going on here?!"
>Sweetie Belle suddenly turns to you
>"Anonymous!  There is a little filly present!  Watch your language!"
>Rarity turns to face you as well
>"Y-Yes, Anonymous...I'm just an innocent little filly...I can't be hearing such awful things, now can I?"
>You recoil from Rarity's sudden change
>This mare of maturity, of grace, of tact, was now calling herself a little girl...
>Sweetie Belle smiles at her "little" sister
>"Now, don't you worry, you silly filly.  Big sister will take care of you..."
>She smirks at you
>"And she'll take care of this stallion's needs..."
>Sweetie trots over to the closet and roots around inside
>"Now, big sister is going to rut her stallion again, and I want to you pay attention and watch me.  But it's grownup stuff and may get boring for your little filly brain, so here..."
>Sweetie Belle throws some paperback books and crayons down on the floor near Rarity
>"Here's some coloring books if you want to have some fun, okay little sister?"
>Rarity just nods, you can hear her juices dripping on the floor beneath her
>"Yes, big sister...I'll try to pay attention through the icky grownup stuff"
>Sweetie Belle nuzzles Rarity's cheek
>"That's my brave, big girl...now come on, Anon"
>She hops onto the bed and lays down as if she was some French girl you were going to paint
>"Let's show this silly filly how it's done, hm?"
>You decide that you had had just about enough
"Sweetie Belle, shut up.  Rarity...oh, god, Rarity...what are you doing?"
>Rarity shushes you, smiling peacefully
>"It's alright Anonymous...go and rut her...any way she wants...I'll just sit here and try to learn something"
"But...but..."
>"Anon..."
>She moves in closer and whispers to you
>"I want this, Anon.  I want you to rut her while I sit here and watch.  For once in my life, I want to be the little filly who gets taken care of and taught by her big sister.  Please, Anon...do it for me?"
>You sigh
>You once said you would do anything for her...you just never imagined it would be anything like this
"Oh, god...this feels so wrong...but if it's what you want..."
>"It IS, Anon..."
>You groan and get off your knees before moving towards the bed
>Sweetie Belle watches your every move
>As you slide onto the bed, Sweetie Belle takes a prone position, her sexy little rump facing you
>Despite your horror, your dick immediately springs back to life at the sight of her tender backside
>Stupid dick...
>"Good, Anon...now take me from behind like a stallion should"
>You slide forward on your knees to where Sweetie is
>You wrap your hands around her waist before turning to look sorrowfully one last time at Rarity
>She nods, giving you the go ahead to fuck her "big" sister
>You sigh and pull her up so that her entrance is in line with your dick
>"Wrong hole, Anon..."
>That throws you for a loop for a second
"But...this is your vagina..."
>"I know that, Anon...but I want to try it the other way"
>You look down
>Oh, god no, she can't be serious
>"You know what I'm talking about..."
>Sweetie Belle shakes her rump at you, flicking her tail aside
"Sweetie...are you fucking kidding me?  I barely fit inside number 1, what makes you think I can do number 2?"
>She giggles
>"I'm sure you'll find a way"
>You move your cock to her other entrance and press on the small, outward facing button of her asshole
>"Mmmmm, yeah...do it, Anon..."
>Jeez, what a whore
>Carefully, you begin to push against the opening
>"Come on, Anon.  You know I can take whatever you can give me.  Put your back into it, you stallion!"
>So, Sweetie wanted to be an adult, huh?
"Happily..."
>Without any concern for her safety, you thrust the full length of your erect cock deep into her bowels
>"Ohhhhh!  Oh, yes!  Oh, rut me harder!'
>You begin to brutally pound Sweetie Belle's ass with long, forceful thrusts
>Once again, the filly surprises you
>She takes the ass fucking in stride, even backing into your thrusts
>You can't tell anymore whether you're hatefucking her or actually enjoying this as you completely let loose, grabbing her mane and slamming your shaft deep into her small body
>You pound her extremely tight hole for several minutes before Sweetie Belle turns to look at her sister
>Rarity is sitting on the floor, watching you two intently and rubbing her nether regions with a hoof, tongue lolling out of her mouth
>"Now, now, little sisterrrrr..."
>Each savage thrust elongates the current syllable she utters
>"Little fillies don't think about seeeeeexxxx, like mares do...you should've gotten bored and started colorrrrrrrring, by now, don't...don't you thiiiiinnnnnkkkk?"
>Rarity suddenly ceases her masturbation and turns her attention to the materials on the ground
>"Oh, oh yes, of course...coloring..."
>She magics up a crayon before Sweetie interjects
>"Ah, ah, ah...oh, harder, Anon...little fillies don't...ohhhhhh...know how to use magic y-yeeeetttt...use your mouth...."
>"R-Right...silly me..."
>Rarity awkwardly tries to grab a crayon in her mouth and begins doodling, sneaking little peeks now and again at you two
>As your ass slamming continues, you hate to admit that this feels almost better than her vagina
>It's even tighter and more pleasurable
>As you continue to saw in and out of her ass, you finally feel the urge coming on
"Sweetie...I'm gonna..."
>Before you can do any more, Sweetie Belle suddenly separates from you and turns around on the bed
>She wraps her lips around your cock and waits
>Oh, what the fuck, she's going ass to mouth?!  You never go ass to mouth!  Everyone knows that!
>But you're long past the point of no return and you cum for the second time today, filling Sweetie Belle's mouth with your hot, sticky reward
>Sweetie doesn't swallow it though
>You can see her cheeks practically full to bursting with the salty substance
>As soon as you're done, she hops off the bed and saunters over to Rarity, still dutifully coloring
>Sweetie grabs Rarity's chin and presses her lips to her sister's
>Horrified, you watch as Sweetie Belle feeds your cum into Rarity's mouth, as if she was a baby bird
>Sweetie Belle, her mouth now empty of seed, pulls back and speaks
>"Now, swallow it, little sister, a lady always swallows"
>Rarity obeys and swallows your cum mixed with shit
>"That's a good girl!  You've made me so proud!"
>Sweetie Belle nuzzles Rarity's cheek
>"Thank you, big sister...I tried to pay attention, but the icky grownup stuff was so boring, so I started working on a picture for you"
>"Oh, that's okay, little sister...I know you're just a little filly and these kind of things don't make sense to you just yet.  But, oh my goodness, you've still managed to make a mess!"
>Sweetie Belle points with a hoof to the area underneath Rarity, who has indeed made a mess with her mare fluids
>"I guess some little filly is going to have to clean that up, isn't she?"
>"Yes...yes, of course she will, big sister..."
>"That's my girl!  And while you're at it, please swap out the sheets on the bed.  I'm afraid my stallion and I have made them pretty messy.  In the meantime, Anonymous?  You and I should probably go get cleaned up in the shower, don't you think?"
>She winks at you, seductively
>You're about to tell her to go to hell, when Rarity motions her head in Sweetie Belle's direction
>"Yes, Anon...you should go...you should go get cleaned up with your mare"
"Rarity..."
>"Can't hear you!  I'm a little filly who needs to clean!"
>And with that, you find yourself walking out of the bedroom, into Rarity's bathroom, following the victorious gait of little Sweetie Belle
>How she was still walking straight after that brutal ass fucking, you will never know
>When you arrive at the bathroom, Sweetie Belle has already turned on the shower and had adjusted the temperature
>"Okay, Anon, let's clean ourselves off"
"Can't we just take separate showers?" you groan
>"Nonsense, Anon!  We're together now, which means we take showers together...besides, I don't know if I can reach all the dirty spots...you might have to help me"
>She giggles and jumps in
>You sigh, just wanting this weird ass night to be over
>While you were naked from the waist down, you were still wearing your shirt
>You remove it and fully expose your body to Sweetie Belle
>"Wow...Anon...I've never seen you totally naked...you're so handsome..."
>You wished that little bit of flattery hadn't worked on you, you wished you could just tell her to get bent...but seeing her wet mane falling about her face in the shower...she looked beautiful...
>You find yourself climbing into the shower with her and finding the bar of soap before getting a lather going and rubbing the suds over your body
>Sweetie Belle just stares, transfixed by your soapy form
"What?"
>"You...you're...beautiful..."
>Sweetie Belle touches your leg
>"Rarity told me once about these things p0nies used to believe in, they were called gods, I think...they were powerful and perfect in every way...it's like I'm looking at one right now..."
>You sigh and crouch down to her level
"And do gods cheat on their girlfriends?"
>"You're not cheating!  Rarity likes it!  She wants you to rut me!"
>Sweetie leans in
>You can't find it within yourself to back away
>"We're making her happy, Anon...and you're making me happy...and don't tell me that you're not happy with all of this..."
>She gets closer to your face
>"With me..."
>Sweetie Belle closes the distance and kisses you
>She backs away, gauging your reaction, before leaning in and kissing you again
>You reach a hand around her head and pull her in, kissing her deeply
>You take the soap and begin to work a lather into her coat, amidst her moans of appreciation
>As the kiss continues, she pushes at you slightly, causing you to fall back against the side of the tub
>The little filly climbs on top of you and presses the opening to her vagina on the head of your, once again, erect cock
>"I love you, Anon..."
>"I...I love..."
>You love Rarity
>Sweetie Belle begins to impale herself on your shaft
"I love..."
>You love Rarity!
>She moans
"I love you, Sweetie Belle"
>She screams in pleasure as she bottoms out on your dick
>And for the third time today, you rut Sweetie Belle until both of you are spent
>Half an hour later, you two finish your shower and return to Rarity's bedroom
>Not surprisingly, the place is completely spick and span
>The floor is clean, the bed has been remade with new sheets, and Rarity is doodling in the corner
>"Oh, you two are back!  Hello, big sister!  Look!  Look what I made for you!"
>Rarity hoofs Sweetie Belle a drawing from one of her coloring books
>It's a simple, color inside the lines exercise...except you can clearly tell Rarity intentionally colored outside the lines in certain places in order to make it look like a real filly drew it
>"Oh, very, very good, little sister!" Sweetie Belle states in an almost condescending tone
>"You did such a good job, for such a little filly, didn't she, Anon?"
>You look painfully at Rarity, holding up the shitty drawing for you to see
"Yeah...yeah, it looks...great..."
>"See, Rarity, even my stallion thinks it's good!  You're such a talented little girl!"
>"Oh, thank you big sister!  I wasn't sure you would like it, being that I am such a silly little filly, but hearing you say you like it makes me so happy!"
>Oh, how the mighty have fallen...
>Sweetie pipes up
>"Okay, well, I think it's time for little fillies to go to bed, now.  So why don't you go run off to your room and dream some sweet dreams, okay little sister?"
>Rarity's face falls
>"But...but this is my ro-"
>"Ah, ah, ah!  This is a room for big girls, not little fillies like you.  So run along now, Rarity...and give Anon a kiss goodnight...on the cheek, darling"
>Rarity stands before you, waiting for you to lower yourself down to her level to oblige her
>You sigh and crouch
>Rarity instantly pecks you on the cheek and recoils
>"Ew, Sweetie Belle, boys are icky"
>Ouch...your heart...Rarity may be playing along, but to hear her call you icky...
>Sweetie laughs
>"You'll learn to like them in time, little sister, you'll learn"
>Rarity then scampers off out of the room
>Sweetie Belle jumps onto the bed and begins shuffling herself under the covers
>"Come on, my big stallion, you and I need our sleep too!"
>You groan and get into bed with her, just wanting to get some sleep and hoping you'll wake up to a sane couple of sisters
>Sweetie Belle snuggles into your side and instantly falls asleep
>Soon enough, you drift off as well
>Before you can dream, morning light wakes you
>You sit up and rub your eyes
>Where are you?
>Oh, right, now you remember
>You shudder from the memories of last night
>You can only pray that things have gone back to normal
>As if your prayer was answered, a familiar, comforting smell graces your nostrils
>Ahhh...Rarity's famous eggs and pancakes
>She had made them for you before, and you had absolutely loved them
>So if Rarity was cooking...that probably means things were back to normal right?
>You throw on your clothes from yesterday and head downstairs
>Please be normal, please be normal, please be normal
>You walk into the kitchen
>Please be...
>Oh, god
>Oh, holy mother of shit, what fresh hell is this?
>As expected, Rarity and Sweetie Belle are sitting at the kitchen table, but...
>"Good morning, husband!"
"Uhhh...husband?"
>"Yes!" Sweetie Belle jubilantly states
>"We're playing house today!  You and I are the mommy and daddy, and Rarity..."
>She motions to her "little" sister
>Rarity is seated at the table...in a high chair...wearing a bib...and to your absolute horror, a diaper
>"...Is our lovely little daughter!"
>Rarity turns to you and smiles
>"Hello, daddy!"
>The nightmare never ends
>You look at the delicious spread before you
"Am I supposed to believe you cooked this?" you inquire, eyeing Sweetie Belle
>"Ummm, yeah!  Yeah, I totally cooked this breakfast!  Because that's what mommies do, right Rarity?"
>"Oh, yes, yes of course mommy!  And it's so good!"
>Rarity has her eggs and pancakes cut into tiny, bite sized pieces on her plate
"So, first she's your little sister, and now she's your daughter?"
>"No...she's OUR daughter, Anon!  Now, sit down and eat, my love, before your food gets cold"
>You quickly conclude that Sweetie Belle has completely fucking lost it, but you grudgingly take your seat at the table
>Rarity pipes up
>"And...and maybe after breakfast, you and daddy can go 'wrestle' in the bedroom and I can watch?"
>Sweetie Belle shakes her head
>"Oh, no, little one.  Mommy and daddy will go 'naked wrestle' after eating, but I'm afraid a foal of your age shouldn't see that kind of thing.  Not until you're older"
>"Oh...right..."
>Rarity's face falls, before turning to you
>"Daddy, will you help me eat my pancakes?  I don't know if they're cut into small enough bites"
>That's it
>You were done
>No matter how much in lust you were with Sweetie Belle, no matter how much you absolutely loved her tight little holes, and no matter how much Rarity said she was okay with this whole role reversal nonsense, you were not about to have Rarity acting like a damn baby
>You decide to put Sweetie Belle on the spot
"So...'wife of mine'..."
>She beams at you
>"Yes, my love?"
"I was reading an interesting article the other day...said that fashion connoisseur Fancy Pants has invested a great deal of capital in a foreign dye company.  Don't you think that's a sound investment?"
>Sweetie Belle looks at you with a confused expression
>"Ummm...I don't know..."
"Well, surely you must have an opinion...these are adult matters we're speaking about.  And being a grown mare such as yourself, you must know all about this kind of thing"
>Sweetie Belle nervously attempts to reply
>"Well...I agree with what you said!  It's a sound investment!"
>Rarity can't help but scoff and then whisper under her breath
>"If you want to lose all your profits to Equestria's extraordinary tariffs perhaps..."
>Sweetie Belle glares at Rarity, causing the latter to slap a hoof over her mouth
>"Uhhh...I mean...mommy!  I can count to seven!  One, two...seven!"
>Sweetie smiles
>"Good try, Rarity!  But you were missing some numbers there.  You'll get better at it though"
>You're not about to let this slide
>"Well, my darling wife, since you think it's such a wise business plan, I was thinking of throwing in with Fancy Pants, investing some of my money in his-"
>Rarity snaps at you
>"Oh, come on, Anonymous!  You can't possibly be so daft as to even consider...Umm, that is...daddy!  I drew you a pretty picture!  It's around here somewhere..."
>While Rarity searches for the imaginary picture, Sweetie Belle leans over and knocks Rarity's drink on to the table
>"Oh, no, Rarity!  You knocked over your apple juice!"
>"Er, no I didn't, mommy, you..."
>Sweetie glares again
>"What I mean is, oh no, I knocked over my apple juice!"
>"That's right, Rarity.  And do you know what a little foal does when she knocks over her apple juice?"
>"She...cleans it up right away?"
>"No!"
>Sweetie Belle was becoming visibly angry now
>"She cries!  She cries like a little baby, because that's what she is!"
>You were about to tell Sweetie Belle what a fucking retard she was if she expected Rarity to suddenly start- holy shit, she's actually doing it
>Rarity was sobbing
>And not like her typical crying, like when a fashion show didn't go perfectly and you had to hold her for, like, three hours on her couch
>Rarity was blubbering and screeching like a little baby
>It was almost painful to watch
>"There, there, precious it's okay"
>Sweetie had moved over to Rarity and began to hold her, rocking back and forth slightly
>"It's okay, mistakes happen...especially for silly little fillies...now who's my big, brave girl?"
>Rarity manages to blubber out
>"I...I am!  I'm your big, brave girl!"
>"Yes, yes you are...oh!  Uh oh!  It smells like some little baby has gone and messed herself!"
>Rarity suddenly stops crying and looks at her sister
>Sweetie Belle narrows her gaze at Rarity
>"Sweetie...you...you can't be..."
>"I am, Rarity.  If you ever want to see me rut my stallion again, you will soil your diaper"
>"Oh, my goodness..."
>"Do it..."
>To your horror, Rarity groans, straining herself
>Then you smell it...
>Oh, for the love of god...
>She actually did it
>Rarity finishes shitting herself and begins to cry again
>You get the sense that this time she isn't faking it
>You lower your fork and push your plate away
>"I made a messy-poo!" she cries out, tears and snot streaming down her once beautiful face
>"Oh, don't worry, my sweet.  You're just a baby, and that's what babies do.  They don't know any better.  Here, here's your bottle"
>Sweetie Belle grabs a bottle full of milk and gives it to Rarity, who proceeds to snatch it in her hooves and chug its contents
>"That's a good girl.  You see, you're just not ready yet for apple juice, you need to drink milk like the little girl you are.  In fact, we need to go even further back..."
>Sweetie Belle suddenly lays down on the table in front of Rarity, stomach facing up
>You notice that the small teats on her lower abdomen look...oh, shit, were they engorged...no, no way...
>"Go ahead, baby, drink up"
>Rarity leans forward and actually begins nursing at Sweetie Belle's teat
>You almost can't believe your own eyes as Rarity seems to be extracting milk from Sweetie Belle, and swallowing it in large, hungry gulps
"Sweetie Belle...how...you can't..."
>She looks sheepishly at you
>"Look... Anon...don't tell Applejack, but I kinda stole cow hormones from her farm last night while everyp0ny was sleeping...they'll make me lactate..."
>She turns her gaze to Rarity and brushes a hoof through her mane
>"...So I can feed my little baby Rarity here"
>She turns back to you and giggles
>"They also make me REALLY horny, so it'll be fun for you too, my love"
>Okay, NOW you've had enough
>You stand up from the table and pull Rarity away from her nursing
>"M-Momma!"
"Shut up!"
>"Anon, what are you doing with my baby?!"
"Changing her diaper!"
>"Oh!  Good thinking, honey!"
>You aren't even listening to her anymore as you carry Rarity to the bathroom
>The two of you enter and you slam the door shut before plopping Rarity down on the floor
"Clean yourself up"
>She looks up at you, pitifully
>"But...but you have to change me..."
"No!  No, I don't!  You know damn well that you are a full grown p0ny and you don't have to take this!"
>Rarity rolls her eyes
>"Well of course I know that, Anonymous.  Goodness, it's like you think I actually believe I'm a little girl"
"Well, maybe it's just me, but it's starting to get real fucking hard to tell whether you're pretending or not!"
>She sighs
>"Anonymous...I told you I want this.  And I mean it, I really want this.  These past 24 hours have been some of the happiest in my life"
"How can you say that!?  How can you possibly be enjoying this abuse!?"
>Rarity becomes indignant
>"It's not abuse, Anon!  Mommy loves me very much!  She takes care of me and loves me, you...you...poopy head!"
>Jesus, Rarity was really buying into this bunk.  She almost seemed so far gone that she was actually starting to argue with you like a real child
"Oh, she loves you?  Is that why she stole your boyfriend from you?  Is that why she taunts you while we fuck?  Is that why she treats you like an idiotic child and makes you shit yourself?"
>Rarity pauses, unsure of how to respond
>"Anonymous...I know it may seem strange, but...I actually enjoy those things..."
"Rare, in what universe are those things enjoyable?"
>Rarity looks away, idly kicking a hoof
>"Anon, I never really had much of a childhood...my mother is an unreliable ditz, and my father was always...distant.  I think he always wanted colts..."
>She looks back up at you and beams
>"But Sweetie Belle is such an amazing mother, Anon!  She cares for me, sings to me, lets me cry and doesn't get angry when I behave like such a silly little filly!"
>Shit...you had no idea Rarity was carrying around this kind of baggage
>"Anon...think about it.  I might actually get a chance at having a real childhood!  One with loving, caring, understanding parents!"
>You groan
"You can't possibly believe that a 'normal childhood' constitutes a daughter yearning to watch her parents fuck"
>"Well...maybe not...but that doesn't mean I'm not still incredibly turned on by it all...watching you two work...for once being the truly submissive one, the cuckold...oh, I could never have imagined such pleasure, Anonymous"
>She stares at you wistfully
>"And I don't think you could have imagined such pleasure either, Anon...my sister certainly knows how to press your buttons, as it were"
>You quickly kneel down to her level and hold her face in your hands
>"But I don't love her, Rarity!  I love you!  I've always loved you!"
>She shakes her head, softly
>"No, Anonymous...not anymore...you love Sweetie Belle now, I can see it in your eyes.  You fell in love with her the moment you came in her mouth for the first time"
"That's not true!"
>"Oh, but it is.  After all, you would have never agreed to go this far if you didn't feel something for her"
>How long had she known?  Had she known from the start, when you avoided her for three days?
>Try as you might to fight the maddening thoughts, you can't help but wonder how right she is
>Could you really feel that way about Sweetie Belle?
>Even as crazy as she had been recently, you could sense that she honestly wanted to take this mothering thing seriously...you don't force yourself to lactate for nothing, after all...
>And she still seemed to be, at some level, the sweet, innocent little filly you had always known
>In fact, this whole "pretending to be a grown up and then failing laughably" stuff seemed to suit her...made her endearing
>Sensing your inner turmoil, Rarity leans in closer
>"It's okay, Anonymous.  You don't have to fight your feelings anymore...you can be with Sweetie Belle.  Love her, hold her, maybe even marry her when she gets old enough.  We could live together here, Anon.  Like a real, loving family...not a very conventional one, but a family nonetheless"
"But...but..."
>"Anon, don't think about it as losing a girlfriend...think about it as gaining a daughter and a wife who both love you very much"
>She throws her forelegs around your neck
>"I love you, Daddy!"
>You reach up and pull her in closer
"I love you too, Rarity..."
>Even though you hear the words leaving your mouth, you don't know their connotation
>Rarity pulls back from you
>"Okay, Daddy, I'm really starting to stink now...you should probably change me"
"Okay..."
>Your mind is so full of fuck, you can't even begin to put the pieces of how you feel back together
>Like a beaten dog, you comply without question as you lift Rarity up to place her across the sink, laying on her back
>Automatically, you move through the disgusting process of removing Rarity's shit smeared diaper and cleaning her nether regions
>You wince as you pitch the foul thing in the trash
>Rarity lays on the table, smiling up at you, naked and clean
"Rarity..."
>You have to try, just one more time, before you give in to this madness, before you give in to the comfortable but strange life of being Rarity's father and Sweetie Belle's husband and very appreciative sexual partner
"I don't want it to end this way...I don't want US to end this way"
>Rarity strokes your arm with a hoof
>"It's not an end, Anonymous...it's a new beginning...you and Sweetie Belle are big grown ups and I'm your sweet, little, innocent filly"
>No hope there...guess it was time to take your daughter back to mommy deares- Wait
"What did you say?"
>"I said it's not and en-"
"After that"
>"You and Sweetie Bell are-"
"The very last thing you said!"
>"I'm your sweet, little, innocent filly?"
>It hits you
>The solution to this entire fucked up mess...was an equally fucked up answer...
>You meet her eyes and grin, menacingly, at her
>"Anon?  What are y-Oh!"
>She recoils a little as you trail a finger along her exposed pussy
>"D-Daddy?  Mmmmph...what...what are you...?"
"I'm not your daddy, Rarity...but I know what I am now..."
>You lean down until your face is mere inches from hers
"You're not the only one who's made some self-discovery here, sweetheart.  You see, one of the main reasons I was so attracted to Sweetie Belle..."
>"Oooohhhhh..."
>Rarity moans as you insert a finger into her
>"...Is because I'm a pervert...a filly fondler...and I happen to have a young, tight, innocent little filly right in front of me, just begging for me to fuck her"
>Rarity's eyes widen in understanding
>"This...this can't seriously be turning you ooonnnnn, ohhh..."
"You tell me, Rare, you seem to be getting into it"
>She pants in pleasure for a moment before indulging you
>"Ohhh, mister...oh, what are you doing to me?  Oh, I'm too young!  I'm not ready!"
>No longer ashamed, your boner begins to tent inside your jeans as Rarity bucks against your finger
>You two are so lost in the moment, you don't even hear the bathroom door opening
>"Anon, what's taking so...WHAT?!"
>You both turn to look an appalled Sweetie Belle
>"Anon!  What are you doing to her!  Get your finger out of there!"
>You oblige her request, but move the little devil to Rarity's mouth, who begins to eagerly suck on her own juices
"Sorry you had to find out this way, wife o' mine, but it turns out your husband can only get off to little fillies..."
>You remove your finger from Rarity's mouth and saunter over to the door way
"I think we should break up, Sweetie Belle.  After all, you're a grown mare, aren't you?  You're just too old for me"
>You laugh as Sweetie Belle's eye twitches
>"B-But...that's...she's your daughter!"
>You sigh, exasperated
"Oh, just knock it off, Sweetie Belle!  Go crusade for your fucking cutie mark or something!"
>"But I took cow hormones for you!  I'm leaking milk all over the pl-"
>You slam the door in her face and turn back towards your "little filly"
"Now where were we?"
>Rarity is sitting up on the edge of the sink now.  Already it seems some of her poise and grace has returned
>"I think we were at the part where you and I and Sweetie Belle are all going to need a lot of therapy after all this over"
>You laugh as you unbutton your fly and ditch your pants, your boner springing upward after suddenly being released from its prison
"I think I can live with that for now"
>Rarity eyes your cock and licks her lips, but tries to stay in character
>"Oh, please don't hurt me, mister!  I'm just a little girl!  I'll do what you say, I won't scream or anything!"
>That sets you off and you move in for the kill, spreading Rarity's legs apart and railing her while she sits on the sink
>What follows is, without a doubt, the best sex you had ever experienced
>Rarity's slight resistance and playing dumb make you hunger and lust for her innocence as you force her to cum over and over again
>When you finally arrive, you cum harder than Sweetie Belle's efforts could ever hope to match
>For a solid five minutes, you and your new found lover hold each other close, panting in the afterglow
>Finally she speaks.  The same, familiar words that she uttered on that day that seemed so very long ago
>"I missed you so, my big, eloquent love..."
"Not as much as I missed you, my beautiful little diamond..."
>And you mean it.  You really, really mean it.  You love her.  With every fiber of your being, you love her and you never want to be apart from her ever again
>And the best part is, from now on, whenever you two decide to enact your little roleplay...
>You won't be thinking of her sister
>You'll be forever thinking...of Rarity
 
The End
