BECOMING BASIC (BASIC SISTER TG) (Patreon)

"Shit shit shit SARAH WHERE ARE YOU?!"

Jack was in a rush to get going, his classes on track to start soon and he was still at home. His sister was supposed to have driven him over but as he yelled for her his phone buzzed, a disheartening, "OMG that was today? Sorry. :::::(" Was she working? Was she with friends? It didn't really matter either way it meant he had to get going fast, but there was another problem. It was really fucking cold out.

He had gotten a good scarf last year, but Sarah never returned it, always forgetting. She was an airhead and while it was kind of cute usually, it was a whole lot less cute when you were depending on her for anything. Still he had to get going, though not without a quick stop as he ran into her room, pulling open her closet to find what he was looking for.

"...this one."

The least girly one in her closet was a red striped scarf, most of the others varying shades of hot pink and purple, his head swimming under the waves of perfume that had settled over all her old outfits with the underlying scent of mothballs. Jack regretted his choice almost immediately, the overpowering scent of pumpkin almost choking, but it was the most presentable option, and he really had to get going, the speed walk to his campus taking about 35 minutes on his best days and he barely had 40 till class started. He wrapped it around three times, stuffing his face into it as he figured the cold wind would quickly dissipate the smell, his nose wrinkling as it shrunk down to a dainty nub. He had to get going, he was gonna be late picking up Jack if he didn't leave now! Er wait no he meant-

Jack's eyes fluttered as he opened his front door, his mind going temporarily slack as his tiny nose kept twitching. He felt dizzy, strands of his brown hair fluttering in the wind, blown longer as the scarf snuggled against his chin with two soft pops. Ugh whatever he didn't like need to think right now he had to get going.

Cold frosted over his lashes, made easier by their gradual lengthening as it darkened to mascara, each determined step clacking on the sidewalk as he speed walked. There was a distracting buzz though every few seconds against his thigh, his phone in a constant frenzy of activity as the muscle in his right thigh softened. Was he getting a call from Jack?

Pulling it out led to a chaotic flurry of texts, various names flashing on his screen as he paused his walk. It felt like each text was battering his brain, so much indecision on who to reply to first LOL~ as each buzz rattled in his palm, fingers shrinking against his phone, nails tapping against the screen as he tried to open it to figure out who all these besties were.

For some reason face recognition wasn't working, a chunkier buzz running through his cheeks as they rounded with the side to side clunk of the failure.

"Ugh c'mooon work you stupid thing!"

His longer nails snagged on a few of the cracks now spiderwebbing through the screen, reminders of how I'm like, such a major klutz it's not fuuuunny~ as he aimed his face at the screen, another failure making him purse his lips in annoyance as they bloated. There was an even brattier intonation as he groaned out an annoyed, "Like, come oooooooon~!" a slight smirk on his lips despite the annoyance, a kind of ticklish airiness rolling over his head with every notification.

It felt kind of nice, each new name and buzz sparking new memories, older ones fizzing and popping as his forehead felt really warm, thinking getting harder as the next failed unlock made him gasp a bit, eyes slanted and green as his forehead squeezed like he was getting one of those head thingies her brother always said really really suuuuu-

POP

"Ooooh~!"

Something had shifted, his rose pink iphone finally unlocking as Jacka cooed, unaware just how hard he was as his phone opened up to his last used message, her brother's text asking where... OMG JACK!

Wait why was he yelling his name like that? Well cause she had lost track of time duh! Good thing she was so close to the house! No what was he doing he was heading the wrong direction and like Jack was gonna be so annoyed if she took any longer.

This mental confusion left him walking in a circle, part of him wanting to rush back home, the other needing to head to class, the deadlock lasting a minute as the continued movement gradually tied his scarf tighter. The warm scent of pumpkin and cookies helped calm him down some, that warmth feeling nice and tingly on his head as he looked down at his brother's message. He couldn't be dawdling, he totally fucked up here. Well she better let him know so he could get moving.

"OMG so so so sorry. Lost track of time I'll make it up next time kay?"

Sending it seemed to cause a glitch, the color wrong at first like it was a received text, flickering between green and blue as a read notification popped on and off. Something similar was happening to his eyes as he stared at the screen, his irises flickering between hazel and a brighter emerald color, thoughts flickering, memories getting all fuzzy and cuddly and stuff hehe~ as Jackah's purpose grew fuzzier. He was like a college student a few years ago right?

"Uhhhhn~?!"

Felt so much harder to think, that flickering message hypnotizing as it strobed, Jackah shivering as the cold ran through his shoulders, each shiver slimming them down a tad, his constant circles making the strain of his backpack slope his shoulders till they popped, a high girlish shriek echoing back as the echo seemed to rise higher in pitch, the warm snuggle of the scarf pushing in his Adam's Apple as his shoulders finished slimming, the straps of his backpack unable to fit as they slid off before dematerializing. Faster and faster his irises shifted till a dink from his phone made Jackah mewl, a heavy blush on he face as he loosened his scarf, green eyes beaming.

"Like what am I doing?"

His voice had a dreamy aimlessness to it, his blush deepening as his cock continued to throb. He looked down at his phone, seeing his message sent though Jack didn't seem to be reading it. Well that probably meant her lil brother had figured something out. He was soooo~ responsible! She'd give him a hug and an apology next time. But wait no he had to get to work. Jackah shook his head, long tresses of conditioned hair fluttering in the wind as he tried to get his thoughts in order. He remembered passing by her brother's room and finding this cuuuute scarf in his sister's closet. And now he had to uh... His lips twitched back to a smile, the more he zoned out the nicer the warm flood of memories trickled in as he stared at his phone, friends sending pics and texts as he remembered all those parties and coworker hangouts and stuff. She really needed to stop by her house more often but her social life was way too-

"N-Noooo~ that's like, something Sarah would think lol. I must be doing too many shifts or something looool. I like need to wake uuuuup~ my body's so sluggish."

His pants felt increasingly weird on him, his right thigh already a little tight inside as the muscle continued to soften, the smooth hairless skin rubbing against his hard on as he stumbled about, half in a daze, eyes scanning for what he was looking for. He had needed something really bad, something about her little bro but he wasn't picking up so it's not like this was her fault. And then he saw it, the thing she had totally been craving. Boba.

"Yaaaaasss~!"

That'd clear his head, and better yet it was so early there was barely any line. Usually she had to go through like, eight alarms to get up cause she'd spend all night doing homework. Homework? Er yeah he was an alumnus so she didn't have to do that annoying-

"Bleh just like staaahp for a second!"

Jackah paid digitally for his boba, shaking the cold beverage with glee, ready to wake up as he stabbed the straw throu-

"OOOH OHH Ohhh~? L-Like whaa?"

The instant he had pushed the straw through a noticeable gap spread open behind his cock, Jackrah struggling not to scream like she was some kind of sluuuut like OMG?! It was a pulsing line of pure pleasure starting right below his navel and thrusting down between his balls as he slapped the straw fully in. He really didn't want any dirty looks so he muffled his squeals with the straw, bubbles blowing through the the drink as his cock twitched, feeling each blast of air make the widening gap rumble and suck.

Each needy breath in through the straw came with a mouthful of juice, Jackrah's eyes rolling up as his scrotum sucked in with each inwards breath, a clear crease forming as it tried to pull in with the pressure of his needy sucking. He hoped it just looked like he was really enjoying the boba, which like she toootally was, this lychee milk tea with a double pump of honeydew was scrumptious. Fuck she should have put up a post on Insta if she was gonna nngh shit no no his cock was gonna burst he was gonna-

"MMMPH? MMMH NNGH!!!"

One of the tapioca balls stuck to the bottom of the straw, a bit too big for the hole as his lips pulled and pulled, his right ball squeezing as it too was tightly mashed against the entrance to his forming slit. He didn't know why he kept sucking, feeling an almost need for the boba, to force it in, twirling the straw as tears ran down his cheeks, the hollow gap stirring his guts as he could feel them starting to pull up, tiny spurts of liquid spraying inside his mouth as he felt it slide, his ball clenching as it sunk up and erupted under a flurry of how good this boba is like hooooly shit it was like sex~?!

SCHLURP

"OHHMGDD OHHMGDD~?!!!"

Jacrah came in a messy series of spurts, his pants soaked in cum as boba flooded his mouth, his other ball sucked dry as it sunk inside with another slurp as his teeth gnashed down, tapioca bursting as his sack imploded, his cock unloading every drop.

"UHHHN AHHHN OHHMYGODOHMY- MM MMM MMMGH?!"

The feeling of his own balls sucking inside was finally enough to break him out of his daze, Jacrah cumming repeatedly as each suck of boba sent more fluids gushing down his thighs. Fuck he couldn't stop sucking, draining the cup dry as his balls rammed deep inside his forming slit, his hips spreading wider as tears of bliss spilled down his cheeks. Oh god h-he was turned on from how fucking good this boba was. She had to make this a regular spot to take all her other-

"MMMMPH MMM MMM~?!"

His hand clenching the boba shrank to match his right, his mewling giggled moans muffled as waves of deliciousness danced along his taste buds, his brain remembering how many of these babies she had downed back in college. God her freshman five was more like a freshman fifteen!

His hands squeezed against his belly, feeling a bit of pudge as the boba hit his stomach, bubbles rising up as he maybe should get another before she had to get out he had to lea-

SCHHLCCK

"OHMYGODOHMYGAAAWD~?!"

Jacrah bolted out the door, moaning as he could feel his stomach bloat flattening, squirming mass and muscle turning soft and toned, the warm, indescribable feeling of his former fat snuggling deep inside, draining deeper, making more wads of cum bust out his cock as he threw the corruptive drink in the trash, desperate not to let any more of himself turn into herself. Th-Thank god he didn't have to worry about more boba since all that fat went straight to my thighs lol~!

"Awawaaa~ noooo!!!"

He couldn't stop cumming, stumbling about as his pants grew sodden with cum, unable to help as memories sparked, his gait turning girlier as his thighs swelled, plush, plump flesh rubbing against his shaft, smothering it in bliss as his hips turned curvy. There was a soft whoosh as he squeaked, the cold wind freezing his cum soaked pants before the crusted fabric shattered, his thick thighs shivering together as his ass got sooo fat lol.

Jacrah didn’t want to be his big sister, he needed help, needed something to perk her up. Ugh she was forgetting who he was though he couldn't run, his underwear shattered when she couldn't believe she had forgotten to put on panties. God like why was all this adulting stuff so hard? She needed to do some laundry stat, but after some caffeine. Ugh her head was like sooo~ dizzy without her morning frappu-

"Shut up Sarah shut up shut uuuuupp~!"

Without panties on Jacrah had to half waddle, squeezing and rubbing his cock every step as his hips began to shimmy naturally, his calves trembling as the cold froze off any hairs left on his slimming calves, his toes squeezing into his thickening sneak- fuzzy cozy Uggs. God like even if she forgot about the cold at least her feetsies were all warm inside her boots. Maybe she could ask her brother for a pair for Christmas? No um, she usually gave out the presents right? Like a good older sister should hehe. Ah n-no but he was usually the receiver hehe receiving. Mmm fuck she felt so wet right now she could really use a-

CLIIING CLING

A door chime rang as Jacrah realized he had just entered a Starbucks, his legs barely listening as he struggled to stop himself, finding himself in line behind five people as the person at the front grabbed their drink and walked, his legs waddling forwards to-

"MMPH MMMM~ AHHHHAHAHA~!! Th-That's crazy!"

He had to play it off, that waddle forwards shoving in a full inch of his cock as he could barely think, his nipples stiff under the softer overcoat, his thighs desperately trying to keep his erection tucked deep inside like that cutie from a few weeks ago. God what a dick on that-

"NO NO N-HOOO~? MMGH MMMPH!"

Jacrah had to smother himself in the scarf, drowning in the overflowing smell of pumpkin spice and various other perfumes, another inch sliding inside as the line shrank in tandem with his cock. God he couldn't hold on he like, couldn't wait for her morning coffee yaaay~!

The line was moving so faaaast, Jacrah whimpering as he continued to bury himself in her usual smell, unable to stop his cock's slow sinking push inside his sist- h-his uhhhn like why is she thinking about her brother right now? That's soooo weird. Then again that like, first time she got her cherry popped... Jacrah remembered the night, trying to sleep as a weird thumping sound kept bothering him from his sister's room as he tried to muffle her screams as Cameron pressed her against the wall. God she hoped Jack couldn't hear them-

"UHHHHN~?"

Fuck there was barely any left, only two people in line, his cock throbbing as his thighs continued to squeeze it uhhhhp. H-He didn't want to know this he wanted to feel it as she screamed for Todd to go harder. No please s-staaaahp. Sarah was like such a ditz sometimes but she always looked after Jack. He was totes adorbs especially when she cuddled up to him. Hehe cuddling mm~ yeah he remembered her cute lil brother sitting in her la-

"AHHHP~!?"

Only one person left in line, Jacrah's lap wet as the smell of coffee added to his mental confusion. It smelled so good, so warm, his mind bubbling over with want as more of his sis- h-her thoughts like kept making her head all hot and needy. There were barely three inches of cock left trembling inside, ready to take his virgin hah yeah like she was a virgin in college. Mmm so many fun study dates turning to-

"Mmm~ oooh fuuuuck..."

Jarah was drooling as he got to the front of the line, memories sparking of lovers and hot, sexy guys rubbing him all over, that feeling of being dominated, of being thoroughly pleasured so addicting as his cock sunk another inch. He needed it like sooo bad, all these half orgasms soooo frustratingly weeeeak. He barely even realized he was speaking when the barista asked for his order, all eight steps of it spilling out his lips cause it felt so right, so like, totally her thing riiiight? He giggled as his cock turned, his remaining thoughts scrambling.

His remaining thoughts were like the coffee grounds, each one being grinded down to powder, delicious, caffeinated powd-

"What name should we put on the cup?"

No no they couldn't aaaask that it was making his brain all bubbly and frothy ooh just like the coffee being stirred into an endless spiral of basic perfection ooh j-just a name just like a silly obvious name. Come on it's Sarah duh. Why is this like a hard question lol? Ooh y-yeah it just felt so nice, so riiiight, the thought of being Sarah, of becoming Sarah, of always being his sisterrgh ow ow head hurty ooh just gotta get my coffee.

"Uh... name?"

The more Jarah thought of himself as Sarah the harder his cock throbbed, not even shrinking, just squirming inside his half-formed slit, the feminine feeling of it stabbing deeper as his insides twisted and boiled over, that thought of saying it, her name, h-his real name.

"S-AHHHRAAAH~!"

He clamped a hand over his mouth but it was already too late, the acceptance thrusting inside as his cock throbbed, feeling something shift deep inside as another few spurts of his own foam followed the various add ons, estrogen pumping through every last inch as his cock grew pliable, soft, so easy to just like shove in mmm~! God I could use a cutie to warm up with on a cold day like-

"Sarah?"

A hot shock rolled through him at being called that, pleasure bursting as he saw brand names twirl around his head like stars.

"Yeah that's like totes meeeEEE~?!"

A few heads turned as he squealed, grabbing the cup, his nipples unbearably hard as he moved towards a booth near the back, feeling the eyes of all these hunks totally glancing up my skirt. It totally feels nice to have so many guys looking ahhhh b-but my dick I-I uhhhn I w-wanna be... Jarah stared at the name on the cup, drooling harder, his dick needily trying to melt as it was drowning in Sarah, his mind doing the same, all the bubbles of resistance popping as she gulped down her coffee.

She needed it, thinking of herself as Sarah, wanting to be her, that need to complete the changes, all of it was finishing as every gulp caused a hot orgasmic burst behind her nipples, the trenta cup massive as each swallow boiled hot coffee to equally hot fat in her chest. She couldn't help but rub at them as they grew, kneading them, moaning cutely between needy gulps as froth and cream spilled down her throat, her thoughts turning just as sweet and sugary as her thighs swelled around her cock.

It was so soft, dimpling with their press, leaving her in a constant state of penetration as she rubbed them back and forth, desperate to drive it in. She like, didn't care anymore about being some dumb college student, her brother adorable but not someone she'd wanna be. And all those cuties eyeing her ooh~ they'd be asking for her number any second and she had to be totes 100% Sarah when they did, h-had to be perfect, bubby baaaasic-

"GYAAAAAWD~!"

The final gulp left her with two jiggly b cups, her cock a crumpled mess trying to fuck its way in as her thighs worked and worked. She couldn't wait even another second, panting as she slid a hand between her thighs, fingers teasing the tip as she pushed. Her thighs clamped together, back arching as she forced the last bit of her little brother inside her, fingering it in till her slit made a sound like a cup sucked dry, her moans squeaking as she came.

Sarah fell into a daze for about two minutes, the caffeine rush thoroughly wiping away any last trace of who she had been, only happy giggles erupting in her brain as the traces left all welcomed the basicfication as she pulled up her phone.

"Ohmygod work! I gotta like, get ready or I'll be late!"

Sarah rushed out the store, only to feel someone grab her arm on the way outside, some tall handsome guy looking a bit nervous, but he was just her type.

"Heeeey haaandsome. Like what you see?"

She did a little twirl and flared her skirt. She could be a little late to work. This looked fuuuun~...
