Nikuyoku - Chapter Three | Commission: Chibi Chi

Daichi was in hell as the cotton sock kept him sealed against his sister’s sweating toes. He had given up moving for now, choosing to conserve his energy in this stinking prison. How had this all happened? And why did he feel the way he did? She was hurting him, humiliating him, yet these feelings…

He wept, his tears mere drops in Rin’s ocean of foot sweat. Suddenly, as had happened many times already, Rin rolled in her sleep and his head spun as he was thrown out from between her toes onto the top of her foot. Her breathing was slow now as her sleep deepened, he could hear the pulse of her blood flowing with each heartbeat as he held his ear against the thin skin on the top of her foot. Being this size and so totally at her mercy sent his mind into total conflict.

He shook away those dark thoughts, he had a life outside of Rin’s sock. He had his education to finish and a career to begin shortly after, his grandfather was going to be his mentor. He had a future as his own person. Didn’t he?

He shuffled his way along the top of Rin’s foot, thankful he was no longer stuck between her toes. Progress! Luckily, she stayed still during this expedition. Daichi soon emerged from her sock into equal darkness under her blanket. Freedom was so close, he began the walk towards the bottom of the bed and noticed the blanket ceiling closing in on him as he got further from Rin.

Eventually the heavy blanket touched the bed on all sides as he stayed clear of Rin’s large mass in the bed. Acting like a tent, Rin’s body gave him the freedom to move around under the blanket without needing to lift it. However, the bottom of the bed was a different story as the heavy, thick blanket lay pinned to the mattress by gravity’s consistent pull.

In an attempt to get out, Daichi gripped the fabric and attempted to lift it above his head so he could crawl through but failed miserably. Moving to a different part of the bed, still away from Rin as he wanted to avoid the danger of her rolling onto him, he tried to lift the weighted blanket again. Failure.

He peered over towards the light at the top of the bed, where Rin’s shoulders lifted it and created a gap where her head popped out. He sighed, knowing his journey was far from over. He knew, however, that it was necessary to pass her and headed back towards the thing that threatened both his freedom and his life, his sleeping sister.

Breathing was easy under the blanket for Daichi, there was plenty of air under there for someone of his size, it was just extremely hot and faintly smelled of body odour down here at the bottom. As he got further up the bed, unable to see much, he breathed again and coughed and sputtered suddenly. Reaching out in front of him confused, he felt the wall of fabric he had just inhaled the odour of - Rin’s foot, of course!

In a lapse of judgement, he dug his face into her sock and inhaled again, allowing himself to take in her intoxicating scent for a moment. Bliss. Shocked at his behaviour, Daichi dragged himself quickly away from Rin’s feet and continued his journey. He had to stay strong, he was almost free.

Almost there, Daichi froze as the giantess beside him began to move. It was too dark to tell how she was moving, he waited for the moment she crushed him but it never came. Soon, the moving stopped and peace beneath her blankets returned.

Just as he was about to continue towards the light, he heard a faint rumble. Was it an earthquake maybe? Suddenly, a blast of putrid, hot air blasted him at point blank range and he realised she had rolled onto her side. Falling to his knees, Daichi choked on the stench as it filled the pocket of air beneath the blanket. Rin slept soundly as the tiny fart slipped between her cheeks, the blanket imprisoning the smell with her brother.

Daichi continued to crawl towards the light, not noticing his rock hard erection as the toxic gas sent him into a haze. Making no progress before restless Rin rolled again, he was pushed down by her ass as she rolled onto her back for what would be the final time she moved that night.

Tired and hopeless, Daichi lay on his front as the giantess’ ass pinned him to her mattress. He lay there pondering what his life had become, and what he had become, for hours in his oxygen deprived haze.

Time was a distant memory here. Rin’s heartbeat thundering through her body in the silent room was the only link to reality he had as he lay sandwiched between her ass and the bed. A few farts escaped between her cheeks, vibrating his body as if he were sat on a washing machine. He coughed and sputtered as the little oxygen he had was replaced by mostly nitrogen that had hung within her shit-filled rectum for quite some time, tainting it with her excremental odour.

Half awake and half asleep, he began to grind into the mattress. He rubbed his erect between the fabric and his stomach, slowly jerking himself off and not fully realising what he was doing. Having forced himself to abstain from masturbation for so long, it took no time for him to orgasm. And he orgasmed harder than he ever had before, leaving a wet patch the size of a bottle lid on Rin’s bed sheets below him.

After a long and deep sleep, light broke through Rin’s curtains as the sun moved over the horizon and into the sky. The songs of birds outside her window filled her ears, slowly waking Rin from her deep slumber. Yawning, she fluttered her eyes open. Serenity.

Rin sat up in her bed, crushing her brother unknowingly beneath her ass as it sank further into the mattress. She had forgotten about him as she thought about what she was going to do today. Daichi squeezed and squirmed to escape from between her cheeks as he could feel the heat from her asshole emanating out onto his back, the smell much worse even just that tiny bit closer.

Suddenly, Daichi was dragged into the air as Rin’s ass cheeks clasped over him as she rose from the bed into a standing position. She stretched her short arms into the air, yawning again and bouncing on the balls of her feet for a moment as her muscles loosened. As she continued to press her feet into the carpet, she felt as if she had forgotten something…

Daichi! Totally forgetting about her brother in her sock, she lifted her foot up towards her and peeled it off her foot. Peering into the sock, she was horrified to find he was missing. Had she dreamt it? Where was he?

Quickly turning towards her bed, she threw her duvet off of it and inspected her mattress. He was nowhere to be found. Spotting something, she furrowed her brow and looked closer. A tiny wet patch on her sheets, too small to be her surely! If she peed the bed it would’ve drenched the entire sheet and herself, yet she was bone dry aside from a little sweat from the heat through the night.

Had Daichi peed the bed? She had just been lying there, her butt had been right there... She flexed her cheeks as she thought about it before finally having a eureka moment as she felt his tiny presence inside of her wedgie. 

Glad to have found him, she bent over and touched her toes. As she did so, her cheeks spread and her wedgie slid out from her smelly crevice causing Daichi to fall to the floor with a thud. Beaming, she shouted down to the tiny boy, “morning Onii-Chan!”

He continued to lie there, too tired to respond with more than a wave towards her. “Looks like you escaped my sock and peed the bed, Onii-Chan!” she pointed out, her smile not giving away what this meant for him. “Do you know what that means?” she asked.

Between his deep inhales of the oxygen-rich air, as he lay there in pain from the fall, he asked “dogeza?”

Rin laughed, “no silly! You need to learn you can’t pee the bed! I’ll let you off with trying to escape since my butt caught you!” she laughed. Daichi made no attempt to explain or argue, her believing he had peed the bed was better for everyone.

Suddenly she raised her bare foot into the air and moved it so it hovered above his body. Daichi watched in horror as it eclipsed the light and ominously hung above. She raised it higher into the air until her knee was fully bent up to her stomach and declared “it’s punishment time, Onii-Chan!” 

Quicker than it had risen, and giving him no time to beg, Rin slammed her foot down onto him and crushed him into the carpet. He wheezed as the oxygen was forced out of his lungs and his body was squished into the ground, he was lucky he was more resilient at this size or else it may have killed him.

Not stopping there, Rin continued to grind his tiny body into the carpet, unknowingly rubbing his erection into it and causing him to ejaculate suddenly for the second time today. Again he left a slightly darker patch beneath his body. She laughed as she ground him into the floor, enjoying the feeling of his bumpy body beneath the ball of her foot and sometimes alternating to pressing him down with her sweaty toes.

This seemed to last forever for Daichi, or a few minutes in reality. The pain he felt in his body was unbearable, yet at the same time, provided him with such pleasure that he had never felt before. Submitting to her will, he made no attempt now to fight back. He even went so far as to grind his crotch a little further into the carpet, milking the semen out of him again and increasing the size of the wet patch in the carpet.

Finally allowing him up, Rin watched as he recovered from his crushing and eagerly awaited his response. As he rolled over onto his back, Rin caught a glimpse at a familiar sight - another wet patch! “Onii-Chan!” she shouted, “did you pee again!?”. Looking closer, she noticed there was no pee on him like she’d expect and realised what it was.

Had he enjoyed being crushed? Was he some sort of freak? Confused, Rin headed for the door in hopes that breakfast might clear her head. She didn’t know how to feel about this. Daichi could sense the tension as he noticed Rin’s smile had faded in place of an uneasy grimace. He watched, more worried about her leaving him alone like this than he had been about being punished by her. Was she disgusted by him? Probably! He was disgusted by himself! He lay there in shame as Rin exited the room.

Suddenly, Daichi grew to full size and was left laying there totally naked on her bedroom floor. She must have grown him back, something must have been really wrong. Rising to his feet, he approached her bedroom door. He could smell her ass and sweat odour clinging to his body, he needed a shower.

As Rin shovelled her cereal down her maw, she thought about what had gone on this morning. Did Daichi truly like being crushed? What did that mean? It seemed pretty strange, she thought. She and Mako exchanged normal conversation as they ate, paying no mind to Daichi’s absence as it wasn’t uncommon for him to do his own thing on a Saturday morning. 

Starving as usual, it didn’t take long for Rin to finish her breakfast and she soon was headed back upstairs to get ready for the day. As she reached the top of the stairs, she crossed paths with her brother wrapped in a towel as he came out of the bathroom after his shower, causing steam to billow out into the hallway. He gave her a weak smile, hoping to get a positive response.

Rin bowed her head, not even looking at him as she passed and scurried towards her room. She still didn’t know what to think so she rushed into her room and slammed the door shut behind her.

The rest of the day was mostly uneventful as Rin stayed in her room, wanting to avoid her brother. She was also conflicted as he had been, adoring her brother but also finding his perversions strange. She wished for him to love her, but he loved other strange things.

As the sun went down and she grew more tired as she lay on her bed sketching, she looked down at the amulet that hung loosely around her neck and thought about how Daichi was still bound to her. Suddenly, there was a knock at her door. She looked at it in silence.

After a pause from both parties, the handle turned and the door slowly creaked open. As it swung fully open, Rin’s mouth was agape with shock. He had fought her advances for so long, yet he had come back to her on his own accord. A deafening silence filled the room as they looked at each other, unmoving.

After what felt like an eternity Daichi finally spoke softly and concisely, as if he had considered his words carefully before this moment, “I do not wish to continue my life at this size, Rin-Chan. I wish to belong to you”.
