"Tati! Get your fuckin' ass out here!"

Fuming, Isabella slammed her fist roughly against her sister's bedroom door as she yelled, using all the air in her lungs to make her presence known. Their parents wouldn't be home for a couple more hours at the very least, so the young futanari had no qualms about being as loud as humanly possible, unleashing her frustration vocally. She banged against the plain, white-wood surface again and again, forcing it to rattle in duress; when that didn't work she grabbed the knob and twisted it as hard as she could, her bicep bulging under the torn sleeve of her black band-shirt.

In her other hand she clutched the ruined remnants of her sex toy, the blue, gel-like object wobbling in tatters between her long fingers, the one that had been in perfect condition only a few days before - before she'd lent it to her sister! Upon arriving home from class only a few minutes earlier she'd found it in its current, obliterated state sitting on her desk, with no hints as to what had caused it to end up like that. Simply seeing the shredded, destroyed onahole sent her into the fit of rage she was feeling currently, Isabella's face beet-red, her bushy brown brows furrowed in fury. She slammed her fist against the door several more times.

"Tatiana! I know you can fucking hear me!" She paused, took a deep breath, and began rearing back one of her military-styled boot-clad feet, "If you don't open this Goddamn door I'm gonna kick it down, and then you can explain that to Mom and Mom!"

Isabella listened for any sign of life in Tati's room for a long second before she planned to make good on her promise. Hearing the sound of scurrying feet coming from the other side of the barrier made her relax and stomp her foot down on the carpeted flooring - though she was still ready to barrel her way in if she had to! Steaming, she waited for her sister to open the door, nearly shaking from how much she'd worked herself up; her nostrils flared with bull-like exhales, her thin lips parted in a menacing scowl. The doorknob jiggled in front of her, followed by the 'click' of its unlocking and the slow opening of the door itself. She glared at the widening gap between it and the frame, anticipating seeing Tati's face present itself for her to unleash her rage upon.

Standing at the threshold was exactly who Isabella'd been expecting to see, in the exact way she hoped to see her. Tati glanced up at her older sister upon opening the door fully, her big brown eyes quivering behind her thick-rimmed, rounded glasses, her youthful visage framed by her freely-hanging, dirty-blonde curls. Her plump, pink lips trembled, and her bare arms were hidden behind her yellow, sky-blue-polka-dotted dress that went down to her ankles, her green-colored toes curled against the carpet. Isabella's sister's face was puffy and red like she'd just finished crying.

The siblings stood in heavy silence for several seconds.

"Tati," Isabella addressed her sister slowly, lifting her hand that held the ruined sex toy up to her eyes, "what the fuck is this?"

"It's a- I'm, I'm..." Tati suddenly burst out into another fit of tears, one that she couldn't hide from her older sibling, "I'm SORRY! I didn't mean to break it, I swear! I just, I just didn't..."

"What the hell does that mean? You 'didn't mean' to break it!? Tati, it looks like you fuckin'... like you fuckin' tried to wear it like a dress! Look at it!"

Holding out the ruined, self-pleasure object, Isabella bounced it up and down in the air between them, showing Tatiana exactly what she meant. The long, tubular onahole that Izzy had spent a considerable sum of money to custom order to fit her specific measurements was split down the middle from end to end, a single tear slicing its gel-like structure in half - and that wasn't the only way it had been wrecked either! Several, ragged holes dotted its still-intact-side, and the elasticity it once possessed had been worn slack, making it appear as though it couldn't grip the appendage it was designed to even if it somehow could be fixed. It was completely worthless now!

Tatiana glanced at the object regretfully before diverting her moistened eyes, a different kind of blush touching her rounded cheeks. Isabella continued to flop the dilapidated sexual item up and down, wagging it back and forth in front of her sister's face, nearly slapping her with it; her muscles tensed as she waited for any sort of explanation from her sibling, readying herself to feel even more anger at whatever excuse Tati came up with. The shorter futanari - as everyone in their family was - sniffled and returned her gaze to Izzy.

"I-I'm sorry, Izzy. I thought I could figure out how to use it without your help, but then this happened..."

"Christ Tati, what happened!? You're supposed to be the smart one - how could you not understand how to use an onahole! You just put it on your dick and fuck it!"

Tatiana cringed at her sister's vulgar, unnecessary explanation.

"But that's exactly what I did!" She burst out in exasperation, sniffling "It... it was really tight at first - kind of uncomfortable actually. I just figured it would, um, be more stretchy! But when I started to- to use it, it just broke! I didn't know that was going to happen!"

"Fuck, Tati..." Isabella put her free hand to her eyes and shook her head, confused, "I don't understand. What do you mean 'tight' - did you try and put it over your balls or something? It looks like you tried to fuck right through the side of it!"

"I... it was just too sma-"

Cutting herself off, Tatiana couldn't find it in herself to finish what she'd been saying; the conversation was hard enough to have as it was, and that was without getting into the specifics! Her eyes darted to her sister and roamed down her muscled, curvaceous figure before falling on Isabella's groin. Unlike the rest of the family Izzy had no qualms about displaying her extra appendage prominently, and today was no different. Bulging out the front of her tight jeans was the visible imprint of the punk-futa's cock, the outline of her flaccid member running down her leg towards her knee, the dark, denim fabric creased around its thickness.

She couldn't help but compare herself to her sister. Though she hadn't seen Isabella naked since they were little, Tatiana was still... aware of the size of Isabella's endowment from her brazen way of dress; while she didn't really know any other futanari outside of her family or have any experience with other people in the way that Izzy did, her daily eye-balling of her sibling's constantly shown-off package had given her a good indication of how her own genitalia matched-up. Or so she'd thought! They'd always seemed similar in that regard, but after this current fiasco with the onahole Tati wasn't so sure anymore.

The onahole had fit - at first! It was incredibly snug around her own member, but Tatiana had just figured that was how it was supposed to be; what good would a loose sex toy be? But as she started to get hard and use the sex toy the way she thought was the right way, it just got tighter and tighter, and the grip it had on her growing member quickly became painful. Before she even had a chance to take it off or try a different method of fucking it, it began to break around her shaft, and, ultimately, ended up in the state it was now. In her panic she did the only thing she could think to do and cleaned it before leaving it on Izzy's desk.

Apparently that wasn't the smartest of decisions either!

" -um, I mean it, I'll just... erm..." Tati babbled for a moment, not wanting to reveal to Izzy that her sex toy was way too tiny - also worried that that might not have been the actual case and she just fucked it up due her own incompetence - and that's the reason it ended up destroyed, "I'll buy you a new one! Or give you money for it or whatever! I'm really sorry, okay?"

Izzy studied her for a long moment, her raging-expression slightly calming.

"...fine." Isabella relented, crossing her arms over her chest, "I'm not exactly happy about this, but I guess if you get me another one we'll be square. How does that sound? Fair enough for you?"

"Y-Yeah..." Tatiana wiped at her cheeks with the back of her hand, drying her calming tears, "But, wait - I don't know where to even buy something like that! Am I gonna have to go to a store and-

"No, you can get it online. I'll send you a link to the site, alright? I'll throw this away and we won't ever have to talk about it again."

"That, erm, works." Tati sighed in relief and showed her sister a small smile, "You won't mention this to Mom and Mom, will you?"

"Ha! Fuck no, 'cause then I'd have to explain to them why I have one in the first place. That would just be fuckin' awkward!"

"Cool, um, thanks Izzy. I'm sorry."

Izzy reached out and placed a hand on the top of Tati's skull, messing her hair with a few swipes of her strong fingers.

"Just make sure to buy me the right one and maybe look for one yourself while you're doing it so we don't have this problem again."

"Um, yeah, maybe..."

"Alright, well I'm going back to my room," Izzy slung the ruined sex toy over her shoulder like a backpack, "gotta find some way to throw this away without the 'rents noticing. Catch ya later, squirt."

"See ya later Izzy..."

Izzy turned around and walked down the second-floor hall to her room, muttering under her breath and shaking her head. That was the last time she let her sister borrow her stuff! She still didn't know how Tati managed to fuck up using something as simple as an onahole, and a part of her might not have wanted to learn the truth. Looking over her shoulder to find Tatiana watching her, she gave her a menacing scowl to let her know she was serious about wanting a new toy. Entering her bedroom and slamming the door behind her, she tossed the ruined sex toy towards a random corner, planning on dealing with it later; first, she needed to see if there were any parties going on that night.

Maybe she'd find someone to replace her onahole for a few days!

...

Several days later...

Tatiana was lounging around the house, doing nothing in particular, putting off doing the daily chores she'd been assigned. Isabella and their parents were both gone - at school and work, respectively - and she had nothing else going on that day. She enjoyed having freedom for the year her Moms allowed her to take off from life, but it often got very boring for the young futa; the few friends she had were in college already or had picked up full-time jobs, leaving her alone for the bulk of every week. Today was much the same, and Tati was currently laid out on the couch in the living room, ignoring the show playing on their TV that she'd already seen before.

Scrolling through her phone, she was actively checking out the website Izzy had texted her, a blush coating her features. It was filled with page after page of every kind of masturbation and sexual-enhancement tool one could buy, some of them so esoteric and crazy in their design that Tatiana had no clue how they worked; she'd added the same kind of custom-created onahole that Isabella used to her cart, cringing at the price tag on it. Her sister really spent that much on something that did nothing but give her orgasms!?

Going through the process of typing in all of her older sister's measurements just reaffirmed Tati's previous suspicions: she really was bigger than Izzy below the belt! While Tati had never bothered to check the exact size of her own endowment, having not understood the obsession that guys her age - and her older sibling, apparently - had with doing so, knowing now what Isabella's were left little doubt in her mind that there was a large difference between them. There was physical proof now to back up that claim as well!

This whole situation did pique her curiosity, however.

A quick, mental estimate was all it took for Tati to realize that she was around the same size flaccid as her sister was erect - unless there really was something she'd missed with the onahole! And, to her own silent embarrassment, she was what she heard was referred to as a 'grower' meaning that she got much bigger when hard, and there was no question that that was the truth; it was something she'd struggled to deal with for awhile now, the unruly mass of her appendage giving her nothing but issues in her day-to-day life. Especially considering that she didn't show off all the time like Izzy did, dressing more conservatively in the same vein as their parents.

Looking through all the sex toys on the website made Tatiana want to both order one for herself and know her exact measurements down there. She just hoped she had enough money saved from her allowance to get her own onahole after buying the replacement for Izzy! But there was one other predicament she was finding herself in as she looked at the different options scattered across the numerous pages appearing on her phone's screen; the size of the toy that Isabella needed appeared to be in the upper range that the company made, and, well... Tatiana was even more massive than that! Did they even make any onaholes or fleshlights for a futa like her, or would she have to do her own searching to find out if they existed?

Knowing she still had plenty of time to herself before anyone got home, Tatiana made the executive decision to find out her measurements for herself. Rolling over into a sitting position, her white, flowy dress brushing against the tiled floor, she paused for a moment of silent contemplation; she would need a measuring tape for sure, but were there any in the house? Maybe her Mom had one in her sewing kit! A deeper blush flaring across her rounded cheeks at the thought of what she had planned, she chuckled nervously to herself before standing up, now very aware of the weight of her genitalia sagging between her legs.

God, she wondered how big-

Ding-Dong!

Tatiana's head jerked towards the front door instinctively, even if she didn't think much of the interruption - it was probably just a package or something being delivered. Yelling out that she'd been there in a second in the hopes that it might keep the overworked package handler from leaving before she could sign for whatever was being dropped off, the short, diminutive futa rushed over to the entrance of her home as fast as her short legs would carry her, straightening out her dress as she went - she had to make sure she was presentable in the presence of a stranger!

Not bothering to peek through the peep-hole, Tatiana unlocked the front door and threw it open, a big smile on her face as she started to greet the delivery driver - but that wasn't who appeared in front of her. A vaguely familiar figure stood slouching on their doormat with his shoulders hunched, one that Tatiana thought she recognized: it was Doug, the cute boy her sister had brought over the week before. His shaggy brown hair curtained his light blue eyes as he stared down at her, and he shifted awkwardly on his sneaker-clad feet; obviously Tati wasn't the person he expected to see at the door either!

Tati was feeling the same sort of shyness that was clearly displayed on the young man's countenance. Despite their differences she found that her and Izzy had similar tastes in partners, even if the reasoning behind their attraction might have been differed - and Doug was no exception. He was taller than she was - which was always a plus in her eyes - and he was clean cut, had been kind to her during their brief meeting before, and kind of dorky looking, all things Tatiana liked in a man. The black Polo-style shirt and fitted jeans he had on really made him seem like the kind of guy you could bring home to your parents for dinner, which was just her type!

As pleasant as this surprise was, Tati found herself caught off guard by the young man's presence!

"Oh, um hi," she stammered as she gazed up at Doug, hoping her blush had receded by now, "it's Doug, right?"

She knew the answer to that already.

"U-Uh yeah, that's me. And you're... Tatiana?"

He remembered!

"Yep!"

"Cool cool. Um," he paused and scratched the back of his head, his pale arm glowing under the midday Sun, "is Izzy here? I didn't see her car in the driveway but I thought I'd check anyway."

Of course that's why he was here!

"Uh, no, Izzy isn't here. She has classes today. Don't you? I thought you guys were friends from school."

"Yeah, but my only afternoon class got canceled. I don't really know her schedule though so I wasn't sure..."

"O-Oh, well..." Tati bit her lower lip and tried not to let the jealousy she was experiencing show - Izzy always had the cutest guys showing up to hang out with her! "Did you want to come in anyway? Um, I-I don't really know when she'll be home either, but you can hang out until she gets back if you want!"

She looked at the older boy hopefully.

"Hang out? Um, I really shouldn't, but tha-" Doug suddenly stopped speaking and narrowed his eyes at the short futanari in front him, his head cocking slightly, "Erm, actually? That would be awesome. Thank you."

"Really!?" Tati nearly did a little jig right then and there, "Then please, come in!"

Doug nodded at her as she ushered him into the large house and stepped to the side to let him enter. She smiled at him as he trudged past her - she was going to get to hang out with a cute guy for a few hours alone! More like her sister than she knew, Tati caught herself checking out Doug without realizing it at first, her eyes immediately fixating on his ass; umph it looked so sexy in those tight jeans! The way his backpack bounced off the top of his cheeks as he moved made them look like a pair of soft trampolines! So tight and round and -

"Uh, so where am I going?" Doug asked, kicking off his shoes and cutting Tati off from her inappropriate flow of thoughts. She gazed back up at him, the realization that she hadn't actually planned for what they were going to do hitting her like a freight train; what did you do when you were alone together with someone you found attractive!? Tatiana knew that her sister would just haul him up to her bedroom and have her way with him, but she wasn't so bold - not by a long shot! Also, she had no idea what Izzy and his relationship actually was! Trying not to panic, she decided to treat Doug like she would one of her normal friends, doing her best to play it cool.

"Let's go hang out in the living room," Tatiana stopped herself from sprinting as she slid past Doug towards the main area of the house, "we can watch TV or something. Did you want anything to drink? Water? Soda?"
