Daichi approached his sister with his now extremely short legs, struggling to close the gap due to his muscle memory expecting it to take fewer steps. Rin, now towering over him, smiled at his little legs! How sweet!

“Oh my! You are so CUTE, ONII-CHAN!” she screamed, struggling to contain her feelings. She held her hands tightly to her chest, scrunched her face and stomped repetitively on the ground, her excitement hard to control.

Daichi halted his approach as the long legs of his previously-little sister stomped down on the ground, threatening to knock him over. Her skirt flared periodically, exposing her panties beneath. Daichi blushed a deep red, his loins warmed slightly. Horrified at his body’s response, he looked away almost pained.

Rin, still beaming with delight, approached her little brother. As she did, Daichi remembered he still had his own totem, and reached into his pocket. The glint from the shiny object immediately caught Rin’s eye as it slipped slightly above his pocket lining.

Jumping to catch the small boy before he could do anything with his totem, Daichi screamed out as the huge girl came down on top of his measly form. As he landed on his back, he felt an intense pressure on his chest.

Opening his eyes, Daichi was shocked to find that Rin was completely on top of him with either leg straddling his chest. He could feel her warm underside pressing into his chest, his loins burned again causing his desperation to get away to kick in.

Rin giggled as her brother squirmed beneath her, causing her to only herself down harder on his chest to keep him in place. Easily, she unfurled his fingers, which gripped the pocket watch tightly in defiance, and took it from him.

Rin sat up fully for a moment, looking as if she were lost in thought. Daichi watched as the giant girl patted her body down, seemingly looking for something. He eyed up the pocket watch in her hand as she continued moving her hands across her body and clothes.

“It looks like my skirt does not have pockets, why do they never give us pockets?” Rin asked, barely frustrated at the problem. “Oh well!” she said simply. Daichi watched as the towering girl lifted her top slightly and exposed her stomach. Following on, she slid the pocket watch down her bare stomach, jumping slightly at the cold metal touching her skin.

The pocket watch soon met her skirt and panties waistbands, she continued on and Daichi watched his only hope slide into the abyss that was his sister’s panties. “Safe keeping!” Rin laughed, satisfied that the pocket watch was safe. The burning in his loins moved to his crotch slightly, his penis flickered up for a moment as he thought about where his pocket watch was. No... He couldn’t have these thoughts! Why was he having these thoughts?

Satisfied she was back in control, Rin climbed off of Daichi and stood over him as he lay still on the ground. “I think you need to learn who is in charge, Daichi. You cannot be trying to get your totem, and don’t think about trying any spells! My amulet has locked your magic until I choose!” Rin explained.

Daichi shut his eyes and turned his head away from between the legs that stood either side of him. He refused to look, this was too much. Shouting now, he said “Stop this now, Rin! This is your last warning! You will be punishe…”

Bending over, Rin cut Daichi off with a single finger to his lips and responded, “No little brother, that will be all from you. I think it’s you who needs to be punished!” Daichi’s eyes widened hearing this. She continued, “I think you should say sorry”.

Sorry? That was easy, Daichi thought. “I’m s..” Daichi began before being cut off again by his sister, this time she used her sockless foot to cover his lips. His penis flickered up again, stronger this time as it hung erect for more than a moment. Daichi desperately tried to soften it as his sister’s toes smeared themselves against his lips.

“No no no” Rin explained before lightly gesturing to the space at the bottom of her bed. Daichi realised what she meant. His face flushed red with anger and humiliation at the thought of such an apology. Dogeza? To his little sister? For what!?

Daichi dared not to challenge such a request from his position with his sister’s toes almost in his mouth, he couldn’t risk them going in. He looked up at the smiling girl, feeling slightly defeated. He’d have to figure this out, surely she couldn’t keep him like this for long. He just had to play along.

Peeling her bare foot off of his face, Rin walked over to her bed and grabbed her favourite magazine to read. Climbing onto it, she stacked a couple pillows for her back and sat down. Peering over to Daichi, who hadn’t yet moved, she called to him softly, “Onii-channnn”.

Looking up at his sister calling him, Daichi saw the same gesture as before, directing him to the bottom of her bed. Reluctantly, he struggled to climb onto her bed at his size. Rin giggled as he pulled himself up with her sheets and began kneeling to her at the bottom of her bed. He was thankful that his head was pressed into her soft sheets as he realised how directly between her legs he would have otherwise been exposed to. He wished she’d be less careless with displaying her… intimate areas. He had seen enough of his sister’s panties for a lifetime and his body’s reaction was conflicting.

Some time passed in this position, the constant tick of her clock and the sound of pages turning filled the otherwise silent room. “Are you sorry yet, Onii-chan?” Rin asked, peering over her magazine at her big brother still bowing at the foot of her bed. Stretching her leg until her foot met his forehead, she shifted his gaze and forced it up her legs until their eyes met. Daichi cringed at the sight, his loins were fiery. It took all of his will to keep her gaze, but he needed to.

“I’m sorry, Rin. I won’t shout at you or try to run. I am yours” Daichi said, hoping to have sold his apology.

“You’re... mine?” Rin asked, her eyes lit up. Daichi’s heart sank as he realised his poor choice of words. Before he could even clarify that he didn’t mean it, Rin suddenly rose to her feet and moved her hand to her amulet. As she had done before, she clicked the amulet again and watched as Daichi began to change size for the second time today.

Before Daichi could even react, he was shot by the beam of light that came bolting out of the amulet. As he woke, his surroundings had changed drastically. The bed he kneeled on had been replaced by an ocean of the same fabric, the drop off of the bed was now a fatal height. He couldn’t have been more than three inches tall!

Feeling her eyes burning a hole into the side of his head again, he peered up at his beaming little sister. Some things never change. She began to speak, “I guess that change really took it out of you, you’ve been asleep for a few hours! You. Are. Adorable”.

Daichi was thankful that Rin was now in her pyjamas, no chance of being flashed. She sat down on the bed beside him and began pulling on her left sock. Daichi was launched into the air as her ass sank into the bed. Landing softly on the duvet, he slid down the incline until he stopped against her pyjama pants.

Seeing this whole thing in the corner of her eye, she giggled. “It’s bedtime now, Onii-Chan. And I don’t believe you’ll stay yet” she explained to the tiny teen. Daichi watched as she grabbed her other sock and then reached over to him.

Gently, Rin plucked her brother off of the bed and held him over her open sock. Daichi squirmed as he peered down at the cotton prison below, she couldn’t keep him in a sock overnight! Suddenly, Rin released Daichi and he fell into the sock, being caught by the soft, elasticated fabric.

His whole world swung as she moved the sock lower. Seemingly out of nowhere, her perfect, manicured toes entered the hole above him and closed in extremely fast. Soon they were on top of him as Rin pulled the sock tightly over her foot. She didn’t usually wear socks for bed but this was a special case.

Satisfied, she wiggled her toes in her pink sock happily. Climbing to the top of her bed, she pulled the blankets up and snuggled herself under. Cosy! Tonight, Rin was truly content. Nothing could make this better.
