>Day hot date in Equestria
>As the day would imply, you do indeed have a hot date tonight
>And it's going to be perfect
>All the preparations have been made just so
>You've gotten your best suit dry cleaned
>For once, you're actually showered and shaved to civilized standards
>You've even managed to get your hair do to that thing she likes
>As you stroll out of the flower shop, bouquet in hand, you take a whiff
>Ahhhh, lilacs...her favorite
>Her...
>You smile as your step becomes lighter and quicker
>She was really something special to you
>The moment you had arrived in Equestria, she had stood out to you among all the others
 >Her poise, her grace, that calm, serene voice that only a true lady of class and deference could muster
>Every time she spoke, it was like a babbling brook was flowing through your body, making your heart bob and drift in its current
>Whoa, hold on to that one, lover boy
>You're going to need all those lines for tonight
>She loved it when you fed her poetic stuff like that
>You were convinced that was a primary reason she had accepted your proposal to go out together in the first place
>And after that...well, how had Rainbow Dash put it?
>"Anon and Rarity, sittin' in a tree!  F-U-C-K-I-N-G!"
>Good to know she could at least spell...
>But she was right, and while you hadn't necessarily done the deed in a tree as her song implied, that first date together had bloomed into the best relationship that has ever happened to you
>Your thoughts are cut short as you arrive at the decorative, circular building that served as both her home and her business
>A small "Sorry, we're closed" sign hangs on the outside of the door...right next to the sign displaying the normal operating hours
>The normal operating hours which clearly state how the store was not supposed to be closed at this time
>Private dining...no interruptions
>Perfect
>Just like her
>You raise a fist to knock at the door
>Before you can finish, however, the door gives way and swings wide to reveal...
>Nyoh, my god
>"What's this?  A visitor?  Oh, but I'm afraid I don't remember ordering anything"
>You find yourself frozen, transfixed by her presence
>Her mane is styled up, her makeup has been applied to perfection, accentuating those large, half-lidded sapphires in her head
>Her dress is a flowing, blue garment
>It's fairly simple, for her taste, but elegant nonetheless
>But what really gets you is the gold
>Her saddle, the hem of her dress, even the frills on her collar shine in a resplendent, yellow hue
>You had told her she should add more gold to her dresses, as it matched her coloration so well
>And you hadn't seen this dress before, which means...
>She made this for you...
>Did you mention she was perfect?  Because yeah, you feel you should say that again
>In fact, you should probably go ahead and say something instead of just stare at her
>Alright, time to go to work
>You give her a bow and begin
"My lady, you did not have to order anything of me, for the winds of love bore me to your presence.  And they would bear me across a hundred deserts and a thousand stormy seas, were it your simplest wish"
>You look up to see her swooning
>She quickly regains her composure, wearing a mischievous smile
>"Oh?  My very wishes are your orders?  Do you have no will of your own, then?"
>You give her a smirk right back
"Fair maiden, I have will.  But any will that I posses, any agency that I can muster against the threads of fate is entwined inexorably to your being, your mind, your very soul, that I might merely stand in your presence.  A pauper in the sight of his queen"
>"So you fancy to give me your will, do you?  And how do I know that you are not merely weak and are prone to give your will too readily to those around you?"
"Because only one such as you are so deserving of it.  Only one of your grace, your beauty, your inexhaustible generosity can rightfully lay claim to my heart and my will"
>She sighs and lays her head against the doorframe, a dopey smile affixed to her lips
>"Well don't stop there, Anonymous.  Tell me what qualities one such as I could possibly posses as to be worthy of such a gentlecolt's heart and soul"
>Time for the big guns
"Lady Rarity...your gaze shines with the beauty of the morning dew, both pleasing to look upon and refreshing to all it touches.  Your alabaster coat would make the white sands of the shore look like a simple mud pit.  Your indigo mane..."
>You are suddenly interrupted by a very pleased, quickly trotting in place Rarity, who squeals and giggles like a school filly
>"Waahaha!  Oh, get in here, you gorgeous hunk of a stallion!"
>A blue aura suddenly embraces and, violently, yanks you inside the house
>You hear the door slam behind you and your body quickly follows it before abruptly coming to a stop against the door
"Ooof!  Rar-"
>The mare of your dreams suddenly alights from the earth and throws herself on you, drowning your speech in a deep kiss
>Pretty spry for somep0ny in a dress
>You bring your arms around her and hold Rarity tightly against you while your tongues slow dance together
>Rarity breaks the kiss with a "mwaa!" and nuzzles your cheek
>"Oh, I missed you so, my big, eloquent, love!"
"Not as much as I missed you, my beautiful little diamond"
>You both hold each other for a spell, nuzzling and smooching each other's cheeks
>That is...until a familiar voice chimes in
>"Ewww...you guys are always so mushy all the time!"
>Rarity's expression turns sour and she whips her head to face the intruder
>"Sweetie Belle...I thought I asked you to wait in your room while I entertained company"
>She's practically hissing through her teeth
>The little, white filly hangs her head in dejection
>"Fiiiine...but seriously, you guys, it was kinda cute at first, but now it's just gross"
>"It's NOT gross, Sweetie Belle, it's called romance.  And don't think you won't learn to appreciate it someday"
>The filly blows a raspberry
>"No thank you.  I think it's ins...insi.."
>She fumbles over her own vocabulary
"Insipid.  The word you're looking for is insipid" you correct
>"Anon!"
>Rarity turns to you
>"Don't encourage her!"
>"Right!  Insipid!  That's what I meant!"
>"Sweetie...room...now!"
>Seeing the wrath in her sister's eyes, the young filly darts off
>"Right!  I'm going, I'm going!  Bye, Anon!"
"Nice to see you, Sweetie Belle!" you call out after her
>You turn to face Rarity, still affixed to your chest, grinning sheepishly at you
>"A thousand pardons, Anonymous.  I've tried to do my part in teaching her better manners, but..."
>You laugh
"It's fine, Rarity.  Kids will be kids"
>She smiles back at you
>"Yes, I suppose they will be, but they can't be children forever...now, come along, darling!"
>She breaks from your embrace and touches down on the floor below her
>"Our dinner will be getting cold"
"Wait.  Rarity, I brought you a little something"
>You hold out the bouquet which had almost been crushed when she had launched herself at your person
>Her eyes go wide and she gushes
>"Lilacs?!  Oh, Anon, you shouldn't have!"
"I'm afraid I just couldn't help myself" you state as you lean down to give her another kiss
>She magics the bouquet out of your grip and canters off towards the kitchen
>"I'm going to get these in a vase right away, and then we can eat"
>You follow her to the kitchen, where you both enjoy the feast she's made for you
>Casserole...garlic bread...red wine...she even put bits of chicken in your helping of casserole
>Yeah, you were DEFINITELY going to have to marry this mare, she was just too damn good to you
>As you lavish well-deserved compliments on the meal, Rarity blushes and waves a hoof, dismissively, at you
>It was her way of saying "Oh, you're far too kind...but please, feel free to go on"
>As the two of you kill off the last of the wine, you volunteer to go grab another bottle
>"Actually, Anonymous..." Rarity states in a low, seductive tone
>"I was thinking that perhaps we could do something else...before either of us becomes too tipsy..."
>Still gazing at you with half-lidded eyes, she reaches up and pulls a pin from her mane
>Her thick locks fall around her face, messily
>"Race you upstairs?" she inquires, raising a brow at you
>She doesn't have to ask twice, as you bolt from your seat and practically fly towards the staircase
>Rarity dives after you, laughing all the way, and the two of you race towards the second floor, giggling and falling over each other like horny teenagers
>As you sprint towards her door you raise an arm and bash into her room, just inches ahead of your lover
>And it's Anon by a nose!  Anon wins the poontang derby!
>As you turn and raise your arms to declare your glorious victory, you're suddenly hit by yet another wave of blue magic
>This one flings you backwards and onto the bed
>Rarity follows, still giggling madly and jumps up on top of you, joining her lips with yours in heated passion
>Ahhh, to be loved and in love
>She breaks the kiss and you laugh once again before stating innocently
"What are we going to do on the bed, Rarity?"
>She looks down at you, smirking
>Her long mane falls around her face and down to the sides of yours, framing her visage for you
>"Oh, I think we're long past being coy with each other tonight, Anonymous"
>You reach up to pull her into another kiss
>She obliges and you feel a tugging at your groin region
>Deftly, Rarity magics open your fly and yanks your slacks and boxers off in one, quick motion
>Huh, she usually wasn't so eager to get your pants off
>Normally, it would've taken a bit more wooing
>Not that you or your erection are complaining, though
>Suddenly, Rarity breaks from this kiss as well and pulls back to look at you
>Her expression is pensive
>"Anonymous, you know I love you, don't you?"
>You raise an eyebrow.  What is this all about?
"Of course I do, Rarity.  And I love you as well"
>She smiles, but only slightly
"What is it?"
>Rarity takes a deep breath
>"Anonymous...I want to ask you a favor, and please-"
"Oh, sweet, sweet Rarity," you chuckle as you run a hand across her cheek
"You already know my will belongs to you, love"
>Rarity closes her eyes and pushes her face into your hand
>The smile has faded from her lips, however
>"I know, Anonymous, but...this favor might seem a tad...strange...at first"
>Kinky sex time?  Oh, yeah, it's kinky sex time
>You had wondered if she had any fetishes beyond, well...humans
>"So...try to keep an open mind, won't you, Anonymous?"
"Of course, my love, anything you desire"
>Her smile returns and she jumps off of the bed
>Confused, but intrigued, you sit up, legs dangling off the side of the bed, still stark naked from the waist down
>Rarity saunters towards the door before turning back around
>"You promise to stay right there, Anonymous?"
"Of course"
>"Say it, Anon.  Say you promise"
>Her tone has a slight edge to it.  It's a little unnerving
"Rarity, I promise"
>"Good"
>She opens the door a crack and sticks her head out
>"You may come in now!"
>The realization hits you
>Oh shit, oh fuck yes!
>A threesome?!  With Rarity and a party to be disclosed momentarily?!
>This truly is the best day ever
>Oh wait...what if it's with a dude?  Uggh, you're not really sure you could stomach that
>But, whomever is out there, you made a promise to Rarity, and you love that mare to death
>There's no way you're backing out of this now...not even if it's...
>The door is pushed open and a p0ny steps into the room
>A short...white...pink and purple maned...
"Sweetie Belle?!?"
>The filly balks at your naked form before you can quickly cover your crotch with your hands
>Sweetie covers her eyes with a hoof
>"Oh my gosh!!  I'm so sorry, Anon!! I didn't mean.."
>Click
>You both turn your embarrassed gazes in the direction of the sound
>Rarity, the p0ny you loved, has just locked the door to her bedroom
"Rarity...what the f-"
>"Ah, ah, ah!  Language, Anonymous!  There is a filly present!"
>Sweetie looks pleadingly at her sister
>"A filly who really, really, really wants to leave right now!"
>"Not yet, darling, there is something that you and I and Anonymous need to discuss"
>Rarity turns to you and dispassionately states
>"Anonymous, please remove your hands from that area"
"What?!  No!!  I'm not-"
>"Anonymous!"
>Rarity looks genuinely hurt
>"You promised me you would keep an open mind about this"
>You can't believe what you're hearing
"Yes, but I never said anything about exposing myself to-"
>Your hands are suddenly wrapped in that familiar, blue glow and are yanked to the side
>"There.  Now it's old news"
>Sweetie Belle turns to look away and shuts her eyes tight
>Rarity moves closer to her sister and nudges her
>"Oh, don't be embarrassed, Sweetie...it's alright, go ahead and look.  You might like it"
>Sweetie groans and cracks open an eyelid
>Her eyes suddenly shoot open at the sight of your member, fully exposed to her now and she turns her head to fully face it
>"It's...it's so big..."
>Yes, right now, despite your best efforts, despite how absolutely fucking wrong this situation was...it was big.  You were sporting quite the massive hard-on
>"That's right, Sweetie Belle, it is quite magnificent isn't it?  Meet your big sister's best friend"
>Rarity chuckles
>"Why don't you two get properly acquainted, hmm?"
>As if in a daze, Sweetie Belle takes a step towards you
>And then another
"Rarity..." you hiss, still unable to move
"What are you doing?"
>This seems to break the trance Sweetie Belle was under and she backs away
>"I-I can't Rarity, it's not right!"
>Rarity nuzzles Sweetie Belle's cheek
>"What a silly thing to say, Sweetie!  Of course it's alright!  Don't tell me all those things you said to me last week about getting weird feelings around some the colts in your class weren't true"
>Sweetie gasps, blushing furiously
>"Rarityyyy!  That was private!"
>Her big sister takes on a haughty tone
>"Now it's nothing to be ashamed of, darling.  You're growing into a beautiful young mare, and what you feel about those colts, and the way you feel about Anon's member, are all perfectly natural"
>Sweetie, still blushing, turns her attention back to your engorged cock
>"Really?"
>"Of course!  Now, as a mare, it is important that you understand and become familiar with a certain skill.  This skill will help you through all walks of life.  Whether it be keeping the attention of a stallion you have your eye on or just buying you some time when you're behind on the rent, this skill is essential for all young mares to learn"
>"W-what skill is that?"
>Rarity laughs quietly
>"Observe..."
>She trots confidently over to you and eyes your erection
>Without warning, she opens her mouth and dive bombs your dick
"Hnnngggh!"
>Sweetie Belle can only stare, mouth agape, as Rarity takes your entire dick down her throat in one fell swoop
>"Whoa..."
>With agonizing slowness, Rarity pulls her lips up and up along your shaft
>Through the pleasure, you look down to find those brilliant blues staring into yours through the entire process
>After what feels like an eternity, Rarity reaches your head and clamps down with her lips, causing a loud POP when she suddenly pulls her mouth off
>"Rarity...how did you?"
>"Oh, that?  That was nothing darling...Anonymous knows I can do FAR more than that with my mouth"
>She winks at you
>Yes, you did know that
>Rarity was a champion cock sucker, she had proved that to you time and time again
>The sudden memories make your dick twinge in excitement
>"And now, darling"
>Rarity continues
>"I'm going to do what any decent big sister should and let you in on some of my secrets.  So that when the time comes, when you find that special somep0ny of your own, you will be more than equipped to keep him happy and satisfied!"
>Sweetie Belle gulps
>"A-And I'm going to practice on A-Anon?" she squeaks out
>"Exactly.  Now, come over here and say hello, Sweetie Belle.  It's very impolite to keep a stallion waiting any longer than he has to"
>To your horror, Sweetie Belle actually licks her lips and begins to approach
>You can't take this anymore
"No, no, no!  Rarity, stop this right now!"
>Sweetie Belle stops in her tracks while Rarity glares at you
>"I shall do no such thing, Anonymous!  This is very important for Sweetie Belle's progression into marehood!"
"But, but I don't want this, Rare!  I don't want to do this!  For god's sakes, listen to yourself!  She's just a filly!"
>Sweetie Belle's expression falls
>"You don't...want me?"
>She plops her rump on the ground.  It looks like she's about to cry
>Rarity gasps
>"Now, look what you've done, you brute!  I never thought you could be so insensitive, Anonymous!  That is NOT the stallion I fell in love with!"
"How could I be so insensitive?!  Rarity, you're basically raping me via your sister!"
>Sweetie Belle sniffs and wipes her nose
>Rarity meets your gaze and sighs
>"Anonymous...this is very important to me.  I love you with all my heart, but I also love my sister.  She needs to learn this.  And I want you to be the one she practices on tonight because I trust you.  She trusts you."
>Rarity leans in and hugs your midsection
>You, of course, can't hug her back because your hands are still magically glued to the bed sheets
>"Please, Anonymous.  It's just one little blowjob...I won't ask you to do this again.  And you promised me..."
>She looks up, pleadingly, into your eyes
>"Am I not still your beautiful little diamond?"
>You groan
>You could never win against those eyes
>And she WAS still your beautiful little diamond...
>You look over at Sweetie Belle
"Are you really okay with this?"
>Sweetie looks up at you, wiping away the onset of tears
>She turns her gaze to your member
>"I...I think I am..."
>Just one little blowjob...from your girlfriend's underage sister...well, maybe you could just think of Rarity and it would be over quick...
"Then...alright.  I'll do it"
>Rarity immediately lights up
>"Oh, splendid!  I knew you would come around!"
>She turns to the dejected filly
>"Now come on, little sister!  We don't have all night"
>Sweetie Belle gets up and approaches you tentatively
>Rarity moves aside to give her full access to your dick
>Sweetie quickly turns to Rarity
>"Will you help me?"
>The big sister smiles
>"I'll be right here by your side, Sweetie, walking you through it"
>Sweetie faces your member and takes a deep breath
>"Okay...let's do this"
>"Good.  Now the first thing you want to do is get him interested.  Warm him up to you.  So why don't you try giving his shaft a few good licks"
>Despite the fact that your dick was already in the "interested" position, Sweetie sticks out her tongue and leans in to touch your member with it
>The minute the two connect she pulls back
>"Whoa!  That's...salty"
>"And...?"
>"And..."
>She smiles
>"It tastes good..."
>Without further prompting, Sweetie Belle leans back in and begins to lick up and down the underside of your shaft as if it were a popsicle
>"Not so rough, darling...that part comes later"
>She giggles and winks at you
>"Just slow flicks of the tongue...that's my girl..."
>You hate to admit it, but Sweetie Belle's warm tongue feels amazing on your dick
>She closes her eyes and begins to move it sensually across the sensitive skin
>"Good so far, Sweetie...now start at the base and slowwwwly lick your way up to the head"
>Sweetie complies and drags her tongue tenderly towards the bulging purple helmet
>"Now, be careful here, the head is very sensitive, so move your tongue in delicate little circles around the circumference of the head.  Good...open your eyes though, darling, and look right into his."
>Sweetie Belle's lids fly open and she meets your gaze
>Her soft, green irises stare deeply into yours
>Oh my god...her eyes are lovely.  Brilliant like her sister's but...soft, warm.  You can't believe you hadn't noticed how cute she looked until right now
>"That's it, Sweetie Belle.  A stallion likes to see that his mare is paying attention to him and not just his equipment.  Also, you get to see how he's reacting and if you need to change your strategy"
>Sweetie Belle suddenly stops licking your head and pulls back
>"Sweetie?  What's wrong?"
>Her face is completely flushed, beads of sweat are beginning to break out on her forehead
>"R-Rarity...I feel all...tingly..."
>Then in a softer tone
>"Down there..."
>Rarity giggles
>"Like I said before, that is nothing to be ashamed of.  It just means you're enjoying yourself.  Feel free to use a hoof on that area if you like"
>"Oh...okay..."
>She moves her mouth forward to continue licking your head while she moves a hoof down south and starts rubbing
>She moans and her eyes roll back a little from the stimulation
>"Very good...see?  This isn't so bad, is it, Anonymous?"
>You're not really sure what to say here, or if you should even speak at all
>Because, to be honest, you are enjoying this way more than you probably should be
>Rarity won't let you remain quiet though
>"Tell her she's a good mare, Anonymous...tell her she's a good little cocksucker!"
>Okay, that surprised you.  You've never heard Rarity say anything that foul before
>"Say it, please..."
>You look down at Sweetie Belle
"Y-You're a good little mare, S-Sweetie Belle.  You're a good little cocksucker..."
>To your surprise, Sweetie smiles happily at you and her ministrations become more aggressive
>Rarity waves her hoof at you, signaling you to go further
"You love that dick, don't you, girl?  Yeah, you suck that cock so good..."
>Rarity snorts
>"WELL, Anonymous, she 'sucks that cock' WELL.  Receiving oral pleasure is no excuse for...
>Sweetie Belle suddenly moans and goes from licking to engulfing your entire cock head in her mouth, gently sucking on it
>Her eyes look up at yours pleadingly, you can see her hoof moving faster on her nether regions
>"Well, would you look at that!  Sweetie Belle, you've moved right on to the next stage without even being told!  And they say a little dirty talk doesn't go a long way!  Now, Sweetie, make sure to flick the underside of his head with your tongue"
>You groan in pleasure
>"There it is...oh, and don't forget to massage his testicles with your free hoof"
>For the first time in a while, Sweetie Belle breaks her gaze with you and turns to her sister
>Cock head still lodged in her mouth, she attempts to speak
>"Tethticleth?  You mean hith ballth?"
>Rarity's brow furrows and she gasps
>"Sweetie Belle!  Such language!  Just because you have a penis in your mouth does not mean you can start speaking like a whore.  You ARE a lady, after all"
>"But you thaid cockthucker!"
>Rarity pauses
>"I did?  Oh, heavens, my apologies...I guess I got a little carried away"
>She laughs awkwardly
>Sweetie Belle turns her eyes back to yours and begins mashing your ballsack with a hoof
"Ugggh!  Oh, god..."
>"Gently!  Gently!"
>Sweetie Belle calms her ball assault down to a tender probing
>"Much better...now, here comes the most important part...you may think you can't do it at first, but you can, you have to believe that.  Are you ready?"
>Without ceasing her very, very enjoyable application of her young, wet lips and tongue, Sweetie Belle replies with a simple
>"Mm hm"
>"Good.  Now, without changing anything else, try to take as much of him into your mouth and down your throat as you can"
>Sweetie Belle's expression becomes worried and she glances sideways at her sister
>"You can do this, little sister.  You've come this far, don't give up now"
>Sweetie Belle returns her gaze to you and steels herself
>Then...slowly...almost painfully slowly, she begins to take you further into her mouth
>She gags a little and retreats
>She blinks rapidly a few times, her brilliant green eyes are beginning to water but the little filly presses on
>Again, she attempts to take you into her throat and, with minimal difficulty swallows about half the length of your cock before stopping
>Rarity claps her hooves
>"Very, very good, Sweetie Belle!  I don't think even I did that well my first-"
>Sweetie Belle shocks you both as she continues to take you farther and farther down her slender, young esophagus
>"Now, don't get too brave, little sister"
>Sweetie Belle doesn't seem to be listening
>She keeps taking you deeper and deeper into her maw
>Your mouth begins to drop as she finally reaches the hilt of your dick and holds you there
>You can feel her hot breath coming in short, quick bursts on your lower abdomen
"H-Holy Shit..."
>"Indeed..."
>Quickly, Sweetie Belle pulls back off of your shaft, eliciting a groan of pleasure from you
>She doesn't take you fully out of her mouth, though
>She's back to sucking at your head and looking into your eyes
>Then you see it
>The fearful, cautious gaze of Sweetie Belle is replaced by something else
>Confidence
>She stares, half-lidded at you, sucking gently at your head
>Her gaze is filled with unbridled lust and eagerness, but also with a smug sense of "I'm going to make you cum for me"
>Without warning, Sweetie Belle begins to take you in again, faster this time and hilting
>You and Rarity both look on, dumbstruck as this little filly takes your entire length over and over again with ease
>The pleasure is unimaginable
>It's like hilting inside a mare, but with her vagina having an expertly controlled tongue inside of it
>Your eyes roll back in your head
"Ohhhh, gooooodddd..."
>"S-Sweetie Belle, mmff, do you...do you think you can go a little faster?"
>Through the waves of pleasure you're feeling, you turn to look at Rarity
>Seems you weren't the only one feeling good about this, as she has taking to rubbing herself with her own hoof
>Getting turned on by watching your sister blow your boyfriend?  That can't be normal, right?
>You were one to talk, you were loving what this little filly was doing to you
>You really, really, REALLY hated to admit it, but...Rarity had never been able to take you all the way in this many times in a row
>Rarity's dick sucking, as good as it was, never felt this good
>And...oh, god...Sweetie Belle takes Rarity's advice and begins to move faster up and down your dick
>Still gazing into your eyes, still massaging your balls, still flicking that devious little tongue of hers
>Suddenly, you feel your hand move from your side
>Yep, more magic, as Rarity places your hand onto the back of Sweetie Belle's head
>Not that you needed much coaxing, as your hand remains there and even begins pushing into her mane long after the blue aura has faded
>"Anon...do that thing...that you do with my horn, ohhhhh...do it...to Sweetie Belle"
>You move your fingers gingerly to the base of Sweetie's horn and begin to rub around its base
>"Mmmmph!"
>Sweetie Belle's surprise at being stimulated seems to send a shockwave through her body, but she doesn't break from her ministrations
>After rubbing the base, you begin to move your fingers slowly up and down her horn.  Not easy to do considering her head was bobbing back and forth with impressive speed
>You take care to stop at each groove along the horn and rub your finger in the indentation
>"Mmmmphh!!  Mmmmmmmmph!"
>Sweetie's moans would be long and loud if they weren't muffled by your dick
>"F-Feels good, doesn't it, little sister?  Yes, keep going, Anon...keep going!"
>You move your fingers to the tip and pinch it hard between your thumb and index finger
>A small, green, static shock emits from the horn and Sweetie writhes beneath you, consumed with pleasure
>Her big green eyes look up at you, so filled with lust, with innocence, with sheer, raw, animalistic pleasure
>You realize you can't hold back anymore...you're right on the edge...
"S-S-Sweetie...I'm...I'm..."
>Rarity suddenly jolts forward and grabs the back of Sweetie Belle's head, slamming it down hard to the hilt and holding it there
>You feel your cock spasm and you unleash a torrent of spunk down her warm throat
>You were so deep, you were probably releasing it directly into her stomach
>As wave after wave of cum spews forth from you, you get the sense that you are filling her up to the brim
>She begins to emit gurgling, choking noises and a small strand of cum flies out her nose
>Rarity suddenly lets go and Sweetie immediately pulls off your dick, beginning to hack and wheeze
>Oh, dear lord, you are still cumming
>Hot, sticky strands fire forth from you and land all over face
>Sweetie Belle tries to move out of the way but Rarity interjects
>"No!  No, Sweetie Belle, open your mouth!  Catch it!"
>The brave little filly shuts her eyes and opens wide to catch the last few streams of cum
>Rarity again tries to assist as she clamps Sweetie Belle's mouth shut
>"S-Swallow, sister...a lady always swallows..."
>Sweetie takes a few big gulps of the hot cum and opens her mouth, panting
>"Rarity..."
>"Not now, darling.  Open your mouth and show Anonymous what a good girl you were"
>"Rarity..." more indignant this time
>"Go on, stick out your tongue for your stallion"
>"Rarity!"
>Rarity lets go of Sweetie Belle and backs up, breathing hard
>"What?!"
>"I-I...I think I m-made a mess..."
>She looks down between her legs
>Your gaze follows her and you see two things
>One, you see a sopping wet fillyhood, with a rapidly winking clit
>Two, a rather large spot of clear fluid covers the floor beneath her
>Rarity snickers
>"So you did...well, it's no matter, messes can be cleaned...and like I said, only natural"
>Sweetie Belle looks at her hooves and touches the cum deposits on her face before turning to face her sister
>"Did I...did I do a good job?"
>Rarity laughs
>"Why don't you ask Anonymous?"
>Sweetie Belle looks up at you.  She looks both ridiculous and adorable, covered in your cum
>"Did I, Anon?"
>You're still breathing heavily
"Sweetie...that was...you were..."
>You can't even finish your sentence
>Rarity laughs again, this time her loud, clear laughter you had come to know and love
>"I think that's your answer, Sweetie Belle!"
>Then to you
>"And you used to be so eloquent!"
>Her laugher fades and she suddenly embraces Sweetie Belle in a hug
>"You did wonderfully, little sister!  I'm so proud!"
>Sweetie Belle soaks up the praise and returns the hug, smiling broadly
>"See, Sweetie?  That wasn't so bad, was it?"
>"Not at all!  It was...wow...it was really fun, actually!"
>Rarity kisses her sister on the cheek and then licks the excess cum off her lips
>"Ah, you truly are my sister...anyway, Sweetie Belle, you should probably go wash up and go to bed.  I'll handle the mess in here"
>Sweetie suddenly yawns
>"Okay...I'm pretty tired, anyway.  Good night, big sis.  Good night, Anon.  And...thanks, you guys"
"Y-Yeah...don't mention it..."
>When Sweetie Belle had left, Rarity suddenly pounces you, knocking you back onto the bed and kissing you fervently
>"Oh, thank you, thank you, Anon!  I know it must've seemed like a strange request at first, but this will do wonders for my sister, I'm sure of it!"
"Of course, my love.  Anything for you"
>She grins and plants another kiss on your lips
>"Now..." she purrs
>"I think you've earned a reward for keeping your promise...how about you let me know when you've recharged and I let you experience a more skilled mare?  Maybe one in similar size to you, hmm?"
>You roll her over and begin kissing her feverishly, amidst her giddy cries of lust
>~20 minutes later
>You and Rarity are sweating it out in the sheets
>You're in both hers and yours favorite position
>P0ny style, face down, ass up.  You slamming her from behind with one hand grabbing her mane and the other slapping her cutie mark
>Rarity, as usual, reaches between her legs to massage your balls through the event
>"Ohhhh, yes, Anon!! Yes!  Yes!  Yes!  Oh, rut me, you magnificent beast!  Rut meeeeee!!"
>Damn, that must've been the fourth or fifth time she's cum this session
>Finally, you reach your peak as well and empty yourself inside of your lover
>As you slump over her, both of you catching your breaths, she whispers
>"Goodness, Anon...enough steam to give both me and my sister our sweet, sticky rewards...humans really are amazing creatures..."
>She trails off as you lay beside her and snuggle her into you
>A bit of pillow talk follows before she finally drifts off to sleep, deciding to leave the mess on the floor until tomorrow
>But you?
>You can't sleep
>Something is very wrong here
>You lay quietly staring up at the ceiling with wide eyes
>Strangely, the fact that not long ago you had ejaculated into an underage filly's mouth was not the thing that was most wrong here
>No, it was the fact that while you had been railing that filly's sister, your lover, the star in your heavens, your diamond in the rough, the absolute love and passion of your life, you hadn't been thinking of Rarity...
>You had been imagining that it was Sweetie Belle
