HRT that makes you a little sister

MONTH 0 YEAR 0

You wrap your dysphoria hoodie around your malnourished frame and shuffle awkwardly in line at the pharmacy. You get your first set of girl pills today, and you're... horrified? Excited? Both? Both. A lot is about to happen to you. Everything's about to change. You wish you hadn't burned ALL your bridges with your family, so you had a sister to learn Girl Things from, but... well, that's what twitter is for, right? Besides, you're a smart cookie. You can figure it out on your own.

You move to the front of the line and blink. Standing on the other side of the counter is one of those Hellhounds you heard about on twitter. She's frankly massive, at least ten feet tall. Fur the color of Twilight and flame the color of Dawn. She slides you a little baggie full of your girl pills and smiles. You tear your eyes away from her absurdist bust to take your pills and mutter a thank you before hurriedly shuffling away, not even realizing that you didn't give her your name until you're out of the building. Well... these are the right pills, so it's fine. You rip the bag open and swallow the first pill right there without even getting a drink first, trying to picture in your mind's eye the estrogen moving through you and converting your flesh. You feel... warm. You smile, and take the first steps in your new life.

YEAR 0 MONTH 8

You stand in line, humming quietly to yourself. You're still in your dysphoria hoodie but mostly because you can't afford anything else just yet. You can see the big pretty hellhound lady is working today too and smile as you reach the counter. She smiles back at you and scribbles something down on your new baggie of girl pills. A phone number? She leans waaaay down, nearly shoving her massive tits in your face, to whisper into your ear. "Call me if you need any help, kay?" then leans back up to help the next person.

You shuffle away, your face as red as a tomato. But... if you need any help, huh? You look down at your hoodie and think. Yeah... yeah. You should do that. Big first you take your first pill of the bottle without a drink, something you've decided is tradition.

YEAR 1 MONTH 3

You prod at your budding breasts and giggle to yourself before the snapping of fingers brings you back to attention. "Oh, uh, s-sorry!" you stutter out. The Hellhound just smiles down at you. "It's okay. It's easy to get lost in your new body." You blush and nod. It's been happening a lot lately. But you're so soft now, and jiggly in the places you've always wished you were instead of the places you hated. You lift your arms over your head so the Hellhound, who has asked you to call her Big Sister, can measure you.

"Just a little A cup right now still, but... way more than you had before, huh?" she ruffles your hair, longer than it ever has been before and you blush again, keeping your arms up so she can wrap a tiny little bra around your chest. Your first one ever.

YEAR 1 MONTH 9

You bounce on your feet in line, more excited than ever before. You got your dosage upped! You got the injectable stuff that's supposed to restore your libido and make your tits bigger faster! You practically run to the counter when it's your turn. Big Sis is there as always, sliding your prescriptions to you. She looks down at you, hoodie replaced with a breezy dress. "Looking good, lil' sis. Want me to come over and help show you how to inject?" You giggle and preen at the praise and then nod your head. "Please!"

You can still feel the warmth of your no-water pill moving through your body when Big Sis shows up, interrupting you from your confused stares at some documents your job told you to go through. You immediately forget about them as you run up to hug her tight. She pets your head and you giggle, a sound escaping your plump lips more and more these days. Then she sits you down and shows you the best parts of your thigh to disinfect and inject, how to make sure there's no air in the needle. She even does the first injection for you. You lean back in your chair, entire body feeling warm. You can practically feel yourself becoming more and more feminine with every moment. Big Sis picks up the documents you were looking at and asks what they are, and you just giggle and shrug.

YEAR 2 MONTH 5

You have a smug smile on your face in line, knowing that everyone's eyes are on you. A few months of injectables have done INCREDIBLY for you and your F cup tits are straining against a tank top while your hips threaten to tear your shorts apart. Life has been AMAZING since you started transitioning! Your head feels fuzzy, yeah, but you followed big sister's advice and stopped buttoning your top all the way up at work and you got promoted! You're your bosses secretary now and you have your own desk and stuff! Swaying your hips up to your Big Sister you beam proudly at her as you gab away about your week to her. She pats your head and you squeal a little bit in excitement, picking up your pills and blowing a kiss to an egg that you catch gawking at you on the way out the door.

YEAR 2 MONTH 10

You frown in confusion at your arm. It's... a little fuzzy looking? HRT is supposed to make body hair go away, right? You don't remember... so you do what you always do when you can't remember something and reach into your H-Cup cleavage and fish out your phone. "Big Sis!" you whine into it, before remembering you have to actually call her with a sheepish giggle. A few minutes of remembering your password and how the buttons work you finally connect with her, and whine her name out again. "Isn't HRT, like, supposed to make me not hairy?"

"Some HRT does that, yeah. Some makes you kinda fuzzy. But Big Sis is fuzzy, so don't you want to be like her?" she responds, nice and slow so you have time to understand every word. You tilt your head like a puppy before nodding. "Yeah! Wanna be like big sis!"

YEAR 3 MONTH 3

You stare in open mouthed confusion at the screen in front of you. There's all sorts of... words on it, you think? It's really really hard to read when there's so many. The little blinky box on your desk starts ringing at you and it takes several rings for you to remember that you have to pick it up. "Like, hiiiiii~!" you chirp into the phone thingy, twirling your ass length platinum blonde hair. It's your boss and he sounds angry, something about you not doing your job? You pout in confusion, he's talking waaaay too fast for you.

Eventually he tells you to come see him in his office so you hop to your hind paws and sway your way there, hips getting caught in the doorframe for a moment which sends you into a giggling fit. He seems less angry in person, 'cause he's staring at your huuuuge titties and stuff! "Y-your work has fallen IMMENSELY in the last few months, you know!" he stammers, trying to put his eyes back on your Midnight colored fur. "You still need to pull your weight around he-- what are you doing?" he asks as you reach into your... uhh... whatever a big letter is tits.

You pull your phone out and push the big button in the middle of it that big sis put there, connecting you straight to her. "Big Siiiiiiiis, my boss is bein' mean an' stuff. What do I do?" you ask her in your high pitched, ditzy little tone. You nod your head with her every word. "Oh, 'kay! That's suuuuuper easy! Love you Big Siiiiiis~!" you chirp, putting your phone back between your tits and dropping to your knees and front paws, crawling under your boss' desk. "Hey! What are you doing down the... oh." he gulps as you fish his cock out of his pants.

An hour later you're back at your desk, globs of your boss' cum still stuck to your face as you giggle vapidly at all the funny little shapes and colors on your screen. Big Sis is always right and makes things sooooo easy for you!

YEAR 3 MONTH 10

You twirl one of your massive pigtails and loudly smack at your gum with your muzzle open, eyes half-closed 'cause opening them all the way takes too much mental effort. You're wearing little more than a three sizes too small tank top and cut-off jeans. Your tits are soooooooo much bigger than your whole head now and your ass is even bigger than that! You feel like a slutty little fucktoy as you instinctively grind your ass back on the person behind you in line, not a single thought going through your head.

"Big Siiiiiiiiiiis!" you cheer when it's finally your turn in line, bouncing and jiggling your way up and jumping into her arms to kiss her hard, your huge little sister cock straining against and breaking the button and zipper of your cutoffs as it gets steel hard. You just stand there swaying on your paws and giggling, trying to remember why you aren't supposed to cum in public as your big sister puts the last of your prescription between your tits and spins you around, slapping your ass hard enough that pre splatters against the floor.

You stumble out the door and try to remember what you're supposed to do now when a pretty boy walks down the sidewalk in front of you and you start to drool from both ends. You follow behind him and eventually catch him at a light, asking if he knows what to do with your pills? By the time night falls you're laying in his bed, absolutely covered in his cum and he covered in yours as you stare at the ceiling and drool. Eventually a thought finally forms in your tiny little brain and you reach between your tits to grab the cum soaked bottle of pills.

You bite the top off and throw each and every pill down your throat, then drop the empty bottle on the floor and go back to enjoying your post-fuck brainlessness. It's not too different from your normal brainlessness, but like, you got fucked before it so it's nicer.

YEAR 4 MONTH 0

You stand on the sidewalk outside of your job, holding a box full of your things. You got... fired? You think? Your boss said soooo many words and you didn't really understand most of them, but he did let you tittyfuck him before he made you leave! You eventually remember to ask your Big Sister what's going on and reach into your torso dominating tits to retrieve your phone, which automatically dials her. Her paws reach through the screen and she pushes her entire body out of it while you just watch with a dumb smile.

"Big Siiiiiiiiiis!" you cheer at seeing and smelling her, cumming a puddle on the sidewalk instantly. "Lil' Sis gots, uh, ummm... uhhh..." you stall, your brain grinding to a halt as your eyes go completely dull. You stay like that, drooling on yourself for a full minute. "Fired!" you finally cry as your brain turns back on. "Wha' that mean?" You ask, head already throbbing and ready to shut down again. Big Sis just pets your empty little head and you giggle stupidly, High Noon colored flame starting to burn around your Midnight colored shoulders. "It means you're finally a full Hellhound, Little Sister. Good job!" You throw your paws into the air and cheer with your Big Sister, not really understanding what she means but excited 'cause she said it. She takes your paw in hers and leads you into a portal to your new life.
