Plot

Artwork: Manarestra

“Hey babe, what are you up to?”

Lucy wrapped her arms around her soon to be husband Matthew. Being shorter than he was by a decent amount, she lifted herself up on his computer chair to peer over his shoulder at what he was doing.

“Watching some anime again? Huh, wait!?”

Matt squinted as he knew what was coming next. He was trying to finish the latest episode of a romance anime he was enamored with. Unfortunately it was ripe with a certain subject matter he knew his girl had reservations about: Sister-Brother teasing… of the romantic kind.

“I knew it, you are watching those incest baiting shows again.” Lucy boasted as she backed up and crossed her arms.

“Come on you judge too harshly. Besides I watch for the, ahem, plot.”

Lucy was unconvinced. “Yeah, uhuh. Your idea of plot is love of the oversized tits variety. I mean look at the size of hers!”

Lucy almost began to laugh before Matthew cut her off and said, “I mean, you swing both ways. You gotta admit she is hot.”

“She is so not my type!” A flustered Lucy denied. Matthew gave a sly smirk back.

“But why all these brother-sister undertones all the time? I mean, I like me some trashy entertainment too, our B-movie nights speak for themselves. But this is…”

“Can we just drop it?”

“Yeah, yeah. Heh, just messing with you as always.” Lucy said as she strutted away towards the washroom to take a shower. “Though you think your own girl would be enough for you. Or am I not sisterly enough?”

With a laugh Matthew replied, “Oh come on don’t be like that. You know you are more beautiful than any of these women.”

He quickly turned to his computer, embarrassed and a little concerned. Whenever Lucy made comments like that he felt a bit guilty. He’d hate to make her feel inadequate. He knew Lucy would mock him for worrying over nothing. Still, he figured he should make it up to her with a nice dinner out. But first he had to get rid of his pesky arousal so he searched up a quick youtube meme video that was a montage of sexy sister characters with huge anime tits. The title was Sister Plot. It was one of his favorite tools for a quick whack. He was simply dressed in a plain, loose fitting T-shirt and sports shorts, so he was all ready to go.

Upon his search he saw a new video however called Sister Plot Awakening. Curious, he clicked on it and was met with a barrage of fast transitioning images of giant anime boobs jiggling about. Unlike the other videos, this was one singular character being shown over and over, a curvy, slightly plump redhead. All sorts of playful sisterly comments spilled from her lips, almost as if she was teasing Matthew directly.

He was already getting worked up, his boner arising to the occasion very quickly while he slipped it out from the top of his shorts. The trance like state of the imagery was agitating his whole body. He was starting to sweat profusely. He’d never felt so worked up before. Some subliminal element to the video must have been having an effect on him.

Suddenly the flashing tits ceased and settled on one clear image of the character’s jiggling breasts bouncing up and down very fast at a smooth 60fps--unheard of typically with Japanese animation. It made the motions of the redhead’s jugs all the more hypnotic. Matthew couldn’t look away, his vision narrowing into nothing but the bountiful glories in front of him. His heart was thumping to the beat of their dance, his mind a slave to their--

He jumped back! A burning pressure in his chest!

Matthew looked down and saw two mounds beginning to quickly push at his shirt. They were growing rather fast, weighing down on his chest as he tried to keep himself steady. His whole body was worked up and pulsating with pleasure all over. With a couple kicks the soft hills that his chest had become erupted further in size. He grabbed at them in hopes of pushing them back in, but his arms merely sunk into the continuously rising cushioned orbs of flesh. His resistance did little but to send more relentless pleasure coursing through his frame, weakening his mental defenses.

“Wait! This can’t be! Are those--hoohh!”

Matthew was suddenly blitzed by bliss and a rush of mind-numbing info dumps. Highly concentrated plot was being dumped into his head. He arched back into his computer chair, the bones in his back and hips cracking and snapping into finer curves, bringing a more androgynous shape to his frame. His stubby fingers pranced about and his hands jittered as all the digits smoothed out into something far more delicate. Both hands clutched into the ends of each armrest, their fingernails elegantly elongated into sharp, manicured adornments. His toenails went through a similar prettying up, decorating each foot that was now scrunching down to a more delectable size. They were the kind of feet smooth and well defined in every nuanced curve, the kind you’d rather put in a glass slipper than hide it behind typical footwear. The arches were poised for heels and the upper slopes of both feet dipped with a royal posture.

Matthew moaned loudly in a rising tone, his voice smoothing out. His head kicked back, allowing his brown hair that was growing silky and long to spill over the backside of the chair and creep down towards the floor. Along its journey, the hair began to stain a bright, passionate red. The apple red color bleeding out from the follicles flowed like liquid down through it.

Next, Matthew’s lower body began to quickly expand with feminine girth, his thighs swelling with fresh heaps of fat to the point of leaving little real estate for his biker shorts to cover as they were stretched out. His ass too was pushing the shorts to capacity, his two round cheeks rising like yeast. The jiggling mounds were suffocated by the clothing trying desperately to contain them and began to find other avenues of escape. His lower bottom partially squeezed itself out from the opening in the legs as the shorts now rode up on his thighs more like clingy underwear wedging. And bigger it became, until the shorts were half devoured from Matthew’s gluttonous behind. His thighs too continued to reach unrepresented levels of thicc from what they were before, squashing his throbbing dick. The top half of Matthew’s penis peeking out from his personal thigh job twitched as if it were gasping for air at the pace of his own frantic pants and pursy moans.

Hearing her boyfriend’s wailing from the other room, Lucy came rushing in to see Matthew squirming upwards in his chair. The extra cushion from his inflating ass cheeks rose his arching back even further, sending his head flinging back over the headrest of the chair and pointing straight at Lucy. His eyes were washed out, but more unsettling to her was the fact Matthew’s face looked drastically more like that of a woman. A new visage was emerging through twisting, pulsating flesh, a visage that was also displayed in flashing neon on the computer screen. It was a beautiful red headed woman whose eyes immediately grabbed hold of her.

“Agh! AHHH!!” Lucy cried out in agonizing bliss as she fell to her hands and knees. The same nerve wracking, brainwashing pleasure that had seized and dispelled any fight left in Matthew was now taking hold of her as well. The plot was all she could think about, the redheaded woman pounding away at her psyche like an unrelenting fuck. The moment she had locked eyes with her on the computer screen, her heart was stolen and her body ready to blossom.

Much like Matthew, Lucy’s body gained more shapely fat and generous buildup within her chest. Copious amounts of plot erupted within her breasts, kicking them up several sizes, her shirt being drawn underneath their immense weight. She slid forward on the floor in delight as they continued to grow, rising her up like miniature medicine ball, before their round shape was no longer fixed. The fat spilled into a more malleable teardrop shape that was squashed on the floor, but sturdy enough to elevate Lucy’s body. Just like her boyfriend, the same gift was bestowed upon the rest of her body as well, big thighs, big ass and all.

“S-So much plooot!!” Matthew cried out, his dick ejaculating hot sperm into his lap, some of it gliding between his thighs and mixing with sweat. This created a sticky, lubricated method for which his cock could glide with ease between the two chunky slabs of female meat. And glide it did, sinking down further between the thighs, receding until it was completely out of sight. Wet slurping sounds trickled out from the crevice as the thighs continued to grind, Matthew’s hips popping out wider the louder the noises became. Eventually his legs exhaled and spread themselves open and he yanked down his shorts even further, revealing a soaking wet pussy trembling to the fresh touch of air, dribbling out some final remnants of cum from the cock that once resided.

“Yes, the plot! So much plot! The best plot!” Lucy screamed as red hair lengthened and flowed down her back and to the floor where it then continued to crawl out in many directions until it became as long as Matthew’s--near full body length. Matthew seemed to relish in Lucy’s remarks, both of her breasts enlarging in response to her girlfriend’s own plot progression, until they reached an even bigger revelation.

The couple were feeling a climax coming on, both of them sensing the end of their sweet buildup to release. They were both excited to see how this plot might resolve, a similar vision entrenched in both their minds as Lucy’s voice cracked before flourishing into a carbon copy tone of Matthew’s now distinctly female voice. They both looked like near spitting images of each other, Matthew simply being taller and with brown eyes to Lucy’s red. But they both were merely shared images to that of the redhead woman in the computer video, who finally blinked out of existence in a wipe to black, her story finished.

A final corpulent gift was bestowed to each of them, both receiving some extra sag to their chest and more pot to their belly, helping them fill out further some extra curves. There was a healthy amount of fatty tissue lining every expanse, giving them a mixed appearance on the fringes of lean and portly.

Their faces flushed red as their hair, both women felt the waves of transformative pleasure cease all doubts and erase much of what they once were, a new brimming, more fashionable personality taking root in each of them that then broke free in shared orgasm. It was a sisterly cry, two alike tones mingling in a moment of rapture. The intensity sent Matthew falling out of her chair and onto her back on the floor, her head tilted up towards Lucy. Both of them locked eyes, seeing the visage that had created them, who they had become, who they always were…

Lucy watched Macy, her sister and wife, finish slipping into her swimsuit. It was the first hot day of summer and she couldn’t wait to flaunt it out at the beach, her body a sense of pride to her as haughty as that was. Macy praised the ever loving crap out of her all the time, so maybe she developed it from that. However, she never thought she quite measured up to her sister. Her… lover.

“Oh? What’s the matter little Lucy? Afraid you don’t stack up again?” Macy teased as she squashed her larger breasts against Lucy’s smaller yet still very large mounds. The two did look almost identical aside form the height and few other size differences. Macy wore her hair in tied up in a side tail and Lucy in twin tails as to distinguish themselves more distinctively.

“Not at all! Hmph!” Lucy jested. “You chew up far too much scenery. I’m fine with being the more refi--”

Macy silenced Lucy with a passionate kiss, her tongue subduing hers.

“Gah, you’re such a jerk.” Lucy said while cracking a smile. “Let’s get to the beach already hot cakes.”

As the two made their way out towards the sandy beach from the dressing area, Lucy took another sly glance at her wife’s enormous rack and then down at her own before saying, “You know, I was always a bit self conscious about myself before.”

Macy gave a laugh as Lucy continued, giving her thanks to a wonderful sister who helped her rock what she owned and feel pride in herself. Macy questioned what was the exact moment it all finally snapped into place for her.

“I don’t know… I guess the plot just finally won me over.”

The couple laughed heartily as they strutted hand in hand onto the beach.
