Rin smiled at the kind, old man who had raised her, “Not quite, Grandpa. I’ll be leaving for the academy first thing tomorrow morning.”
“A tough thing. You both have grown up so fast. Daichi is out exploring the world now and you’ll soon also spread your wings. I am so proud of you”, Mako said as he moved towards Rin for a hug. The two embraced for a moment, both thinking back over the years of happiness they’ve had in their home.
As they parted, Mako held the girl he had raised and looked at her once more, “I have packed all you need to write home, if you need anything at all just let me know”.
Rin smiled warmly at her grandpa. She had stopped fabricating the letters from Daichi long ago, it was a charade she simply couldn’t spare the time to keep up. Perhaps this was Mako’s way of ensuring she doesn’t also disappear from his radar, as her brother had seemingly done. “I’ll write to you often, Grandpa. Don’t forget, I’ll be wanting to keep my eye on you as well!” Rin laughed.
Mako chuckled heartily at Rin’s remark. “Well, I’ll leave you to it. I’ll see you off in the morning!” he replied before turning to head out of her room. As he slowly closed her door behind him, he said, “Goodnight, Rin”.
“Goodnight, Grandpa!” she affectionately called back through the closing door before it clicked shut. Sighing, relaxed, she continued to fold her clothes and neatly line them up in her suitcases. Tomorrow really was a big day. It would be her first day at Fukan Academy, the same academy her grandpa had gone to when he was her age.
Rin was already an immensely powerful sorceress, her abilities, especially in size control, had surpassed all expectations. The amulet she had previously used to control Daichi’s size was no longer needed; it was simply a sentimental, decorative piece to remind her of her humble beginnings.
She was extremely thankful to her grandpa for his work in getting her into Fukan Academy. It was the top school for Magic and Sorcery, and reserved for only the rich or noble-born. Luckily for Rin, she fit the requirements.
Folding her final piece of clothing, Rin decided it was time to relax before sleeping for her long day tomorrow. Grabbing the towel she hadn’t packed yet, she made her way out of her bedroom and into the bathroom. Moving over to the bath, she put the plug in and turned the hot tap on. The water blasted out of the spout into the large, copper bath; slowly filling it up.
Hot steam soon filled the bathroom as Rin removed her clothes. She shimmied her body out of her skirt and tights before dropping them carelessly to the floor. Pulling her top over her torso, she left only her petite, naked frame standing in the bathroom as she tossed that garment to the tiled floor also.
The warmth of the steam relaxed her tense muscles, from a long day of packing, to no end. Looking at her figure in the misty mirror, Rin ran the palms of her hands down the length of her soft skin; her touch soothing. Light squirming against the inside of her asshole reminded her finally of Daichi. He had been shrunk down to his most common size of one centimetre and kept inside of her ass all day, stored somewhere safe while she did the various tasks she had set herself in preparation for her departure tomorrow. Usually she’d get him out before he was entombed in her waste, but judging from the pressure building up she had left it a little late.
She enjoyed the feeling of being backed up, especially when Daichi was squirming back there as he was doing right now. Her loins began to burn with lust, it really had been a long day. And she had only one thing on her mind.
Daichi couldn’t get any closer to Rin’s sphincter, her ever-pressing shit was slowly pushing him towards her exit. He squirmed against her elasticated flesh, trying to worm his way into the open for a well deserved breather.
With the bath almost half full, Rin climbed over the side and dipped her toe into the hot water. It burned her skin in a way in a way that she enjoyed, so she looped her remaining leg over and into the hot water too. Holding onto the sides, she slowly lowered herself into the water and felt her ass cheeks squish together as they both pressed down into the copper base. She felt Daichi squirming in response before moving deeper inside of her.
Daichi’s plan for fresh air was foiled as he squirmed his way out of Rin’s sphincter, only to be met by the pressure from her compressed cheeks around his exposed head. He clenched his eyes shut and held his breath as he realised she must have been in the bath. Knowing his only opportunity to breathe was back inside, he shimmied his way deeper until her sphincter released him and he fell down into the remaining space in her rectum. He gulped in the air lavishly, choking from the pain inflicted on his lungs by the toxicity of it.
As the rushing water filled the bath further and covered her shoulders, Rin sighed peacefully. Satisfied with how full it was, she stretched her leg out across the bath and wrapped her toes around the hot tap before twisting it slightly. The water soon stopped and silence filled the once noisy room.
The muffled sound of rushing water finally ended and Daichi could hear Rin more clearly through her flesh. The one consistent noise to him was her consistently booming, thunderous heartbeat that filled his days. And every so often he’d be treated to more situational noises that gave away what she was doing in the outside world, one of those situational noises had been a long, drawn out sigh as she settled into the hot water.
Lazily she slipped her hand between her legs and found her waiting vagina. Feeling so tense lately, she was really looking forward to a little alone time. With the moisture from her bath, she easily slipped her fingers between the folds of her vagina; her body tingled as she teased her sensitive skin.
Feeling extremely horny as Daichi continued to press against her sphincter and move around across the remaining ridges of her filling rectum, she dug her fingers deep inside of her and stroked the farthest reaches of her sex. Her breaths quickened in response before one of her longer exhales turned into a pleasured, sensual moan.
As Daichi inched back towards her sphincter, not wanting to be entombed by her shit, he felt it tighten in front of him. Wondering why, he approached and stroked it lightly until it twitched and gnawed on his tiny hands. Suddenly, a muffled, bassy moan reverberated through her feminine body, indicating to Daichi exactly what was happening.
Sinking deeper into the bath, Rin retracted her fingers from inside of her vagina and moved them to the top of it. Rotating the tips of her fingers in a circular motion, she gently caressed her clitorus. Frissons of pleasure rippled their way up her back as her lustful feelings increased with each passing touch. Daichi’s light movements against her sensitive sphincter only served to further fuel her passionate masturbation.
Knowing he could do nothing but ride out the storm, Daichi crawled right up to his sister’s sphincter and heaved his tiny body into a seated position against it. Taking a deep breath in, the air was especially potent with her sulphur smelling waste. He knew it was barely inches away from consuming him and then he’d to be retrieved from the toilet, his lesser preferred method of being retrieved.
Taking short inhales of the noxious air, Daichi stroked his hardening penis. Whilst he’d rather not be plucked out of a pile of her waste, he certainly couldn’t dispute how turned on she could make him. His ears were filled with the thunder of her heart combined with her periodic, lustful moans. His penis grew with every passing moment, each pleasuring stroke of it serving to send his entire body into ecstasy when combined with the ripe odours that filled his anal prison.
As Rin increased the pace of her masturbation, her moans became quicker and louder. She furiously rubbed her sensitive clitorus as her muscles contracted in ecstasy. “Oh… Oh… Oh…” she repeated aloud as her self-love continued. She slid deeper into the water as her body straightened out, loving the feeling of her muscles stretching as she approached her climax.
Due to her erratic movements against the copper of the bath Daichi tumbled slightly from his seated position jerking himself off and rolled against her ridges, narrowly avoiding the mass of sludge that ominously lay in front of him. His penis throbbed longingly as he weakly climbed to his feet. Having an idea to serve them both, Daichi climbed back towards his sister’s sphincter before pressing his whole body against it.
Carefully he slid his hard member in between the folds of her sphincter and began to thrust himself in and out of it. The soft folds gripped his erect penis firmly, acting as a perfect fleshlight for him as his own masturbation progressed.
Her moans became sharper and louder until they were only high pitched gasps as she furiously played with her clitorus. Daichi’s movements against her asshole had become more noticeable and consistent, pleasuring her to no end. She pressed the bottoms of her feet against the far edge of the bath to hold herself in place as she reached the peak of her self love.
Daichi continued his thrusts into his sister’s tight anus, also approaching orgasm. Despite their size differences, the two of them were perfectly in sync. Rin could feel herself reaching her climax just as Daichi felt the same, his testicles tingled as they prepared him to ejaculate.
Rin powerfully rubbed her petite fingers over her entire vagina as waves of euphoria coursed through her. Her body contracted powerfully, causing her limbs to straighten and her toes to curl. She clenched her sphincter down over her brother, unknowingly clenching his penis in its grip and holding it there.
Daichi could no longer thrust as the tight asshole of his sister held his penis tightly. He felt the walls of her rectum press down on him and force her waste closer to her hole until it touched his back. He simply held his body up against her sphincter, kept there by its grip and begging for release.
Rin moaned out loudly in ecstasy at the peak of her climax. She clenched her sphincter down harder once more as the ripples of pleasure shook her entire body, inadvertently milking the semen out of his penis and finally allowing him release.
She slumped into the water, thoroughly satisfied. With her eyes shut and her body glowing in post-orgasmic bliss, Rin lay there surrounded by the still warm water happily for a time. Tired, she dropped her arm between her legs once more. Only this time she used her finger and thumb to dig slightly deeper.
Flexing her rosebud outwards slightly, she felt around the folds of her asshole for any sign of Daichi, who she knew had been pressed right against it. Daichi, recognising what she was doing, wormed his way through her sphincter as much as he could until the tips of his hands met her prying fingers. She easily tugged his slime-ridden body through her asshole and into the deep, warm water.
Daichi was only submerged for a brief moment before Rin lifted him to the surface and placed him on the side of the bath, paying him no further attention. He watched as his giantess sister didn’t even look at him, her magnificent body cut through the huge body of water with ease as she rubbed her sponge across her supple, faultless skin.
Barely noticing his presence, Rin reached over to grab her shampoo from the side. Daichi couldn’t even make out a scream before her dripping wrist struck his tiny, wet form and sent him falling towards the floor of the bathroom below. He landed with a thud against the bath mat just where Rin would place her feet upon climbing out. Slowly he made his way towards the centre of the bathroom floor, unable to see Rin’s movements but hearing her slosh around in the water as she cleaned herself.
Finished bathing, Rin climbed over the side of the copper bath and exposed her wet, delicate form to Daichi. He could stand and observe as the almost planetary girl absentmindedly stepped onto the bath mat where he had just been. Reaching down beside her, she plucked up the towel she had brought in with her and wrapped it around her body.
Bending over, she reached into the bath to unplug it. Daichi’s jaw dropped as the towel lifted slightly over her bare ass and exposed her plump cheeks. He was shook out of his trance-like state as she lifted the plug out of the bath and turned towards the door. He dived out of her way as her feet, dwarfing him easily, came booming past and only narrowly avoided him.
With one hand on keeping her towel around her body, Rin clicked the fingers on her spare hand by her side. Suddenly Daichi grew to three feet tall and waddled out of the bathroom after her, making sure Mako was nowhere to be seen as he made the run across the hall. Not even looking at her still short brother, Rin sat down at her dresser and commanded, “Brush my hair”.
He didn’t even know she knew where he was, yet she had altered his size and seemingly knew he had entered her room as if there were never a single moment where she hadn’t been omniscient. He stood there awestruck by his younger sister’s awareness and poise, she was a far more powerful sorceress than he had ever been.
“Well?” she asked, growing impatient but still never turning her vision to spare him a look. Daichi rushed over to her and plucked the hairbrush up from the dresser. It was huge in his hand, but this wasn’t an uncommon task. She’d often grow him to various sizes to help her with things, what was the point in having someone you had full control over and not exercising it?
Lifting the brush above his head, Daichi pulled it gently through her silky, blonde hair. Making sure to get a long and thorough stroke, he lifted the tips of her hair as he brushed through to the edges. Rin sighed, relaxed, before simply stating, “Thank you, Daichi”, in her almost tsundere tone.
