Boredom

The cozy bedroom was almost entirely silent if not for the loud clicking of a mouse and the clacking of keys on a keyboard. The main light of the space was shut off as it had so been for most of the day, yet a decent amount of the room was visible thanks to the bright computer monitor. It flickered every so often, the brightness either dimming or increasing with each shift to a new tab or window. Making the noise of the computer's tools were two chubby, beige hooves - belonging to a mare named Screen Light. She sported an over-sized pair of green glasses atop of her diamond blue eyes, her mane all curled up in curlers after a shower.

Her expression was one of annoyance and slight anger. "Oh for fuck's sake.." she groaned, finding that all of her favourite games had either decided to do updates or certain maintenance today.

Highly unusual event - so much so she'd never seen it before - which made it all the more aggravating. Screen took some time to think a bit. Now all her plans for the night were up in the air; she had wanted to play with her friends, and even had all her food prepared to tease them with some belches into the mic, but now that wasn't happening. Heard across the hall in the next bedroom over was a yell of anger from Backbone - her older sister - as she shared Screen's plight.

Mindset shifting to boredom, the younger nineteen-year-old subconsciously reached a hoof down between her legs, spreading them as much as possible. At this point any pony nearby would notice something different about her - there was not only a marehood there, but a cock as well. Shivers of pleasure trickled through her body as her hoof made contact with the shaft and even more as she pressed down, rubbing up and down gently. Though she kept herself quiet, Screen let a pleasured moan out of her mouth as her hoof reached her tip and gently rubbed her uretha. As her hoof gently pushed past and starts slipping down, ideas came to mind. Kinky, naughty ones that quickly merged with her boredom to give her an immense craving for an act she had not been able to perform in ages - stuffing somepony in her cock.

Visions and fantasies began popping into her mind. Her brother had been staying over for the last few days - not due to anything important, just being so lazy he got fired for neglecting to perform simple duties that were at-home work anyways. Neither sister really had a care for him or his friend who had tagged along, they only were taking up food and space. Screen could handle not having him in her life anymore - in fact, she was so confident she knew that no matter how much he'd yell, Backbone would do nothing to stop it. The useless sibling of the family was about to become cum in his sister's balls and there was absolutely no way he could stop it.

Getting her jiggly, tubby rump off of the red gaming chair, a hoof quickly tapped a button to shut off her monitor prior to her trotting over to the bed. Sound asleep was her brother - easy prey for her. Not even caring to attempt keeping him asleep - she oh so loved the squirms whenever she made a meal of somepony, cock or otherwise - she grabbed him roughly by the head and plopped her plump body down on the bed, shaking the mattress enough to make his head shoot up as he awoke.

Despite being the much chubbier and exercise-hating pony in the room, Screen was much stronger than her older brother; so much so that his kicks were barely anything worth calling an escape attempt. His mouth opened to speak, but instead he got a mouthful of thick marecock. Having been paying zero attention, this inspired a sudden, loud moan from Screen. While it was not originally part of the plan, did she really have any reason to complain? Quickly she moved her hooves to push his head down as far as it could go until her balls were even stuff in his mouth. A bulge was visible in his thin throat as she thrusted her cock, feeling an immense amount of pleasure. Not only was his tongue forced to taste and somewhat lick it, but his attempts to get her out only made his throat squeeze and rub the shaft and tip he was being deepthroated with with its wet warmth.

Unfortunately this couldn't last very long as that could cost her cum, which would trickle down his throat. In her point of view, this idiot didn't deserve a single drop from her. "Ooh...thanks brother, your little contribution is gonna make the next much better.." she chuckles, a small tease to her voice.

He yelled but whatever he said was muffled by her cock still. For a few minutes more she'd continue to thrust, making sure he would gag on it with every single harsh push, knowing exactly how to trigger the reflex. Though she did soon become bored of this as the craving shook within her balls to fill them up.

"Ready to become a bunch of cum in my glorious balls, brother?" Screen smiled with a tease, lifting his head up. The stallion could barely even register what was being said and done to him before she smashed his head into her urethra.

The force caused a loud squelch as his head popped inside of the cum-covered flesh walls of her cock. He could feel himself slowly sliding down, not making a move himself as he was simply in shock at this point; in shock because never would he have assumed Screen would do this sort of thing to him. Before his head would be too deep and completely get his speech muffled, he made one last-ditch effort in an attempt to get himself out of this situation, yelling to Screen.

"H-h-hey...Screen. C-cmon.." He stuttered, finding the proper words proving to be a difficult task for him, "l-let me go..please?"

Screen scoffed, moaning at the feeling of his form slowly sliding and squishing into her shaft. The bulge he made was big and round, getting a smack of the lips from her as she watched it slither downwards. Of course she would never let him go - he felt too heavenly descending towards his cummy, sticky doom in her dick. Not caring about him in the slightest except as a source of seed, Screen would give him the silent treatment towards his plea. She reached to her shaft and gently began rubbing it, eyes roling back as the rubbing caused the internal walls to tug her cockfood down further.

"Oooh...fuck..." the mare moaned in a low, deep tone, her eyes turned to the sight of her brother slowly dissapearing down her shaft. As his ass got closer and closer to her, she got a good view of his cock, which jiggled as he gave small wiggles in a vain escape attempt. In fact, this only prompted him to get tugged further and faster.

A gruesome idea came to Screen's mind - one that would provide her with much pleasure, her cockmeat with much more pain, and a very organic dildo. Wrapping her mouth around the stallion's cock before it became erect, she bared her teeth and chomped down, tearing the flesh and muscle connecting the appendage to his body. Pulling her head away, his screams of pain turned to muffled screeches of agony as she ripped his dick off, careful to not let the testicles fall out. She laid it gently on the bed sheets next to her, staining them with droplets of blood as she reveled in the stallion's agony and horror, which would quickly turn to loud sobbing and crying.

"Oh, what's wong, widdle baby?" she mockingly cooed, rubbing her shaft more more vigor and pleasure than before now. As his rump began going towards the urethra to follow her body, she gave it painful spanks, leaving deep red imprints of her hooves in his skin.

Soon the stallion had exhausted his supply of energy, the noise from his hardly audible begging and pleading now completely gone as a new sensation overwhelmed Screen's nervous system - the feeling of her balls massively expanding as his head popped inside. Squealing, she shifted her body to face a hole in the middle of her bed and began thrusting her bulging, pulsing cock in and out of the soft hole. A goofy, ecstasy-filled expression took over her face as this caused the process of her cock swallowing him to go much more quickly, balls expanding significantly as his body was pulled down entirely into the sticky chambers. Soft plops were heard as his ass spilled inside, splashing what cum was already inside her balls around.

No more resistance would come from the exhausted and deteriorated pony, reluctantly and sadly accepting this new turn of events and his fate. there was nothing he could do to stop Screen or hinder her, and even if there was he hadn't the energy to move whatsoever. While he was drying out his eyes out with heavy sobbing, Screen was continuign to thrust to shake her balls and stimulate her well-erect marecock, causing the walls of her testicles to begin squeezing painfully on the stallion within her. The pleasure coursing through her body was next to unimaginable, every squeeze and thrust rocking her body to the point it felt she might collapse.

Nothing of any sort came from her brother, despite the immense pain he was being put through as the balls crunched his bones and dissolved his skin, churning it up into a pony's worth of cum in his sister. So badly he wanted to call for Backbone or his friend to help, but at this point he knew it was helpless. Already his hind legs and shoulders were decimated beyond repair, ground up and filling the chambers with more of the sticky white fluid. It began rising up to where his muzzle laid, filling into his nostrils and mouth. This clogged his airways and he began suffocating, choking and coughing. Though between his lack of energy and the rising of the liquid, it would not get any less torturous.

It began seeping into his eye sockets as his torso was absolutely destroyed, though by this point it was barely felt. Most of his body was simply gone, ground into nothing but cum in Screen's balls. Within seconds he passed out, both from the loss of most of his body and the clogging of his respiratory system via the rising cum. Screen took notice of this and ceased thrusting as to not lose the batch, squishing down on her balls to finish the job.

"Ah...what a great use of an idiotic brother." She panted heavily from pleasure, tongue sticking out in ecstasy. Light pokes from her hooves came onto the now much larger, rounder and squishier balls.

Looking in her mirror she let a suggestive purr out. "Damn, those are some SEXY balls!" She giggled, shaking them and watching the sway in her reflection.

Some thoughts came to her mind, making her gleefully rub her hooves together and smile. Her brother's friend was just as worthless and pathetic as he was, nothing but a burden on her and Backbone. Her sexual wantings still not sated, Screen made a decision - to churn the friend up into her assfat, and maybe later she would shit out his remains into Backbone's mouth.
