>Rarity drops off Sweetie, who runs inside and takes her stuff to your guest bedroom.
>She thanks you profusely for watching her little sister for the week.
>hands over a bag of groceries and various toiletries
>"oh, and if she asks for help with her... exercises, just play along and do what she asks. I certainly don't approve, but father says it's good for her to have a hobby and mother just seems to think it's cute."
>"it has done wonders for her self-esteem, I suppose. Do take her shopping if she needs, but she's supposed to be buying product with her own money."
>before you can ask what the hell she's talking about, Rarity is already leaving.
>you wish her a nice trip and take the groceries to the kitchen
>thank fuck Rarity thought to bring some food, otherwise the poor kid would be eating hot dogs and beans all week
>there's pasta, veggies, milk, all sorts of stuff
>what the hell?
"Yo, Sweetie! What's the deal with this flaxseed oil? Am I supposed to cook with this or what?"
>"That's for me, I'll take it!"
>fucking kids and their oil, these days
"Uh, sure. Anyway, I'm going to start cooking dinner. Spaghetti alright?"
>"sure! I'll be right back!"
>she grabs her oil and scampers off
>time to get your cook on
>you remember how to make things that don't involve the microwave, right?
 
>it's a good twenty minutes before she's back from whatever she was doing
>just in time for dinner, at least
>the two of you share some idle chit-chat over the meal
>which is mostly just Sweetie complaining about how Rarity never lets her do anything fun
>"and she keeps trying to get me to wear bras! Like, I get that clothing is her thing, but no way am I keeping these things all strapped down!"
>She wiggles a big, trying to show off her (mostly) flat chest
>you just nod along, trying to figure out how you're supposed to keep her entertained.
>"besides, why would I want to wear some dumb lacy bra when my milk starts coming in? I'd just ruin it anyway."
>what in the actual fuck is she talking about?
 
>at least she helps with the dishes
 
>after dinner, you figure you'll put on a movie to keep her busy
>maybe a nice, wholesome action flick.
>Perfect! Terminator 2, a hundred and thirty-something minutes of thrilling robot action!
>that'll hold her all the way through to bedtime
 
>thankfully, she's actually in to it
>it's about half way through the movie when her watch chirps
>"Oh! Mind pausing it for a sec?"
>whatever, it's that boring part in the desert, anyway.
>she runs off, returning a moment later with a towel and the bottle of oil.
>"Hey anon, you've got pretty big hands, wanna help me with something?"
>you think this is almost certainly a bad idea as you resume the movie
"sure, what's up?"
>she pops off her shirt and climbs in your lap
>what the fuck
>"can you massage my breasts for me? Just fifteen minutes or so!"
>Rarity's encouragement to "play along" echoes in your head
>their family always was a bit out there
>what the hell, might as well go for it
>in an insane world, it was the only sane choice.
 
>whatever, it's going to be a long week if you can't keep her happy
>might as well oil up and give it your best, right?
>she shivers a bit at your apparently cold hands, but otherwise manages to sit still
>you start with a gentle touch, but she whines and tell you to really get after it
>fuck it, she wants you manhandle her? You can manhandle her.
>god, her skin is so soft
>her nipples poke out ever so delicately
>and here you are, pawing and squeezing like a goddamn animal
>there's not much there, just a bit of extra padding, but you're working it and she seems to appreciate it
>soon enough, she hops off your lap and towels herself dry
>"Thanks, anon! You're way better than Scootaloo, but we'll need to work on your technique."
>this fucking kid
>at least she settles down and gets back in to the movie
>leaving you to sit and think about how you're totally going to hell for this
 
>the next morning, you're munching on breakfast when she comes running in.
>"ohmygosh ohmygosh ohmygosh, look! I grew so much last night! You're totally going to have to do all my massages from now on! I never grew this much on my own!"
>she's got on a tank-top and sure enough, it's a bit more filled out than it was last night.
"that's very nice, Sweetie. Are you really sure we should be doing that, though?"
>"of course! I've been trying for weeks to get bigger boobs. Looks like you're my key to success!"
>she punctuates this by taking a long pull of milk straight from the carton
>well, you can't rag on someone for pursuing their dreams, right?
>"so come on, it's time for my morning session!"
>she practically pulls you out of the chair and on to the sofa.
>if Sweetie wants you to grow her boobs, then by God, you are going to grow her boobs.
 
>while last time you pretty much just had free reign to mash at her chest, this time she's she's intent on making you do it right
>you even remembered to your hands nice and warm for her
>so now you're basically letting her guide your hands in concentric circles, working from the outside on
>you give her now-puffy nipples a light tease before she whines and forces your hands against her chest
>fine, you'll give her a good kneading
>with a "thanks! I'm gonna go take a shower now!" she pops up and leaves you alone and bewildered
>you had hardly even gotten started, had it you really been at it fifteen minutes?
 
>A few minutes later, she walks in wearing a pair of board shorts and a bikini top
>"it's so nice out, can we go to the pool today? At least for a little while?"
>you agree, thinking it'll be good to get her out of the house
>it's not like you had anything else planned, anyway
>so you walk her down to the pool, send her off, grab a deckchair, put on your headphones and take a nap in the sun
 
>you awaken to hear a chirping watch and Sweetie poking your shoulder
>oh come on, she doesn't really expect you do to this in public, does she?
>the look on her face assures you that she does
>rather than get yourself arrested, you lead her to the unisex restroom between the locker rooms
>with the door firmly locked, you take a seat on the toilet and get to work
 
>your moment of semi-public indecency complete, you send Sweetie back out to swim and return to your nap
>you're not sure how long it lasts, but soon enough some jackass kid splashes you awake
>since it looks like you're starting to burn, you figure that's enough
"Hey Sweetie Belle! Come get your stuff, it's time to go"
>"Aww, alright."
>watching her climb the ladder out is something else
>she is undoubtedly starting to fill out
>watching the water cascade down her body only emphasizes the effect
>you lecherous fuck
"Go get showered off, and think about where you want to go for lunch"
>"Milkshakes! Where can we go that has milkshakes?"
"There's a burger place nearby, we'll go there."
>"Awesome! Be right back!"
 
>the burgers are good
>the shakes are good
>the fries are good
>and goddamn this girl can pack down a meal
>at least she's getting your money's worth of the unlimited fries
>you're not really sure how someone her size can down a double burger with egg, bacon & all the trimmings while still finishing a shake and lord knows how many baskets of fries
>but this girl can fucking eat
>sure, she did skip breakfast and had an active morning
>but what the heck
>with the cutest little burp she announces she's finally had enough
>so you settle out and head back home
 
>you're cutting through a park when you hear that faithful chirp of her watch
>you take a quick look around, but there's no bathroom in sight
"Not now, Sweetie. You'll have to wait until we get home."
>she looks like you just drowned a kitten
>"b-but..."
"oh come on"
>"please? there's no one around"
>you are kind of tired from the walk, it would be nice to have a seat for a bit
>and you haven't seen anyone else for a while
>oh whatever
"fine, geez."
>with a jump and a cheer, she gives you a hug and leads you over to a bench
>as usual, she's got her top off and she's in your lap as she pulls the flaxseed bottle out of her bag
>yup, definitely going to hell for this
>prison too, probably
>whatever, it's worth it to see her smile, right?
 
>you're a few minutes in to a trance-like state of kneading and massaging when you feel it
>there's something different about the oil
>well, not the oil itself
>it's like it's polluted with something, more watery than usual
>you write it off and go back to work
>eventually you give each one a firm squeeze, and shoo her off
>enough is enough, empty park or not you're still in public in the middle of the afternoon
>at least she seems satisfied as she towels off and gets dressed
 
>you're back at your place
>she was going to get changed, but but apparently she only got as far as taking off her shirt
>"Anon! Look!"
>she's cupping her bikini top, it's clearly more full than it was, even when you were leaving the pool
"I know, Sweetie. You're getting pretty big."
>"no, not that... but I totally am, right? But look, wet spots! My milk's starting to come in!"
>...
>you're pretty sure a teenager should not be producing milk
"uh, is that supposed to be happening?"
>"Sure is! My book says that happens when you rub them enough, even if you're not preggers."
>thank fuck, apparently that's a thing?
>"Can you take me to Zecora's shop?"
>Why does she want to go visit that weird lady that lives outside of town?
>Surely no good will come of this
"Yeah, alright. Go get dressed, we'll leave in a minute."
 
>"Ah, Sweetie Belle, my diminutive friend. How goes your quest to enlarge your front end?"
>As if Zecora couldn't see her cleavage
>Pretty sure she should not have that kind of cleavage at her age.
>Of course, when you're standing six foot six with your own set melons your perspective might be a bit off.
>"It's going great! I finally started milking, do you still have that pump I was asking about?"
>"This enchanted pump should do quite fine, and it can be yours for merely nineteen ninety nine."
>Sweetie pulls out a wad of cash and counts it out
>"Oh, and some more flaxseed oil too, I've almost finished that last bottle."
>"Sure! For free, I'll include a serum of aloe vera. On chapped or sore nipples, it's good to smear-a"
>"Ooh, thanks! You're the best!"
>The amazonian shopkeep simply smiles and nods as she bags up the purchases.
>Ever bubbly, Sweetie practically skips towards the door.
>You take a moment to lean in ask Zecora what she thinks.
"Hey, between you and me, don't you think it's a little odd for her to be so... enthusiastic about her tits?"
>"The dreams of others, I do not judge. What's poison to a dog, is to you: free fudge."
>you think on that for a moment, before realizing she's holding out a plate of fudge bars
"huh, thanks!"
>another smile and nod sets you at ease
>the delicious chocolate helps too
>there's something to it, maybe a bit of cayenne?
>that, and something else that's hard to place
>whatever, looks like Sweetie's at the car and eager to get home.
>with a final wave, you're off
 
"A milk pump, huh? You've really going at this, aren't you?"
>"Yup! Once I get going with this thing, I'll really start seeing some gains!"
"And just how big are you planning to get, anyway?"
>"I dunno yet, but I'll know it when I see it!"
"Right, and you're not worried about overdoing it, like, at all?"
>"Nope!"
>Well then, what's the worst that could possibly happen?
 
>You figured she'd start pumping as soon you were home, but apparently it's time for her yoga routine
>she says it's to keep her back strong
>which is fine by you, you've got a date with your couch
>maybe there you'll figure out why your body is so goddamn heavy
>and why you feel so light
>oh goddamn it Zecora
>you forgot she also runs a dispensary
>must have been "medicated" fudge, because you're clearly high as fuck
>between the new-age soundtrack, the weed and the little show Sweetie Belle has decided to put on in your living room, you're feeling pretty good
>she's looking pretty good too
>considering in the span of a day she's gone basically flat to carrying around a couple of apples on her chest
>and oh what a pair they are
 
>a familiar chirp brings you (slightly) back to reality
"Let me guess, you want me to pump you now?"
>"Not exactly"
>the predatory look on her face might concern you, if you weren't the epitome of relaxation right now
>wait, why's she straddling you like that
>oh come the fuck on
>really
>shirt's off, she's lowering her bosom to your face
>is this what's happening?
>"Go on, drink up."
>yes, this is what's happening
>she guides your head in and you instinctively latch on to a nipple
>a lusciously salty-sweet nipple
>that's not just sweat, that's milk
>there's not much, it's more of a dribble than a flow, but that's milk
>"mmmm, that feels so good!"
>she giggles as you give the nipple a lick, trying to coax out the meager flow
>evidently, she can tell when she's running dry, as she pulls back and presents the other
>again, you latch on, and again you're rewarded with a trickle of sweet, sweet milk
 
>It's a couple hours before you start to sober up
>apparently she was content to pump herself and watch you play video games all afternoon
>but now you're fuckin' starving and you're pretty sure she is too
"Pizza okay? I'm not really in the mood to cook."
>"Sure!"
>god she's so bubbly
>it would be sickening if it weren't so cute
>you dial 'em up
"Yeah, a large hawaiian for delivery?"
>"get a large meatlovers too!"
"and a large meatlovers too"
>a growing girl needs her protein, you guess
 
>a knock at the door
>you're still a bit loopy, so you toss Sweetie your wallet and ask her to take care of it
>she says you're silly when you're like this, and does so
>fuck yeah, pizza
