Nikuyoku - Chapter Four | Commission: Chibi Chi

A year has passed. Mako headed out to the front of their home to get the mail. Shuffling through each envelope, he walked back towards the house. “Bill… Junk… Bill… Junk...  Oh Daichi!” he said aloud. Opening the door, he called up the stairs, “Rin! Your brother has sent us a letter from his travels, come read it with me!”

Rin quickly rushed downstairs, seemingly eager to read the letter. She ran straight past her grandfather and sat patiently on the seats that overlooked their garden cross-legged. Mako smiled at the excitable girl, she did always love her brother. She undoubtedly missed him very much!

Mako followed her to the seats and perched himself on the end of them as if reading her a bedtime story. Carefully, he ripped open the envelope and pulled out the plain white letter. Unfolding it, he moved his glasses further up onto his nose in preparation to read the handwritten text.

Rin sat in front of her grandfather smiling as he began to read the letter. She had to be convincing that she didn’t already know the contents of the letter, for she and Daichi had planned it out in its entirety. 

“My beloved family”, Mako began, “my travels to the vast lands of Kaede have been full of excitement and wonder. I am deeply sorry that I cannot be there with you both right now, however I am certain that we shall meet again in the future. It is fated.” Mako looked up from the letter at Rin, she smiled at him as he did. He smiled calmly in return before looking back down at the letter.

“I understand it was extremely sudden for me to leave. This felt like something I had to do to grow as a person”, Mako read out. Rin sat as still as she could. She didn’t know why Daichi insisted on staying in her armpit while she listened to her grandfather reading the letter. He was squirming a lot in there and she was ticklish!

Mako continued reading, not noticing Rin squirm as she pinned her arms to her sides powerfully, “A year ago, I learned a lot about myself and knew I had to explore further. This past year has proven to my previously conflicted mind that Kaede is part of my destiny”. As Rin began to sweat from her nerves and Daichi continued to tickle her smelly armpit, she felt him suddenly slide out from her armpit’s grasp and fall out onto the chair. Rin’s eyes widened in horror as their entire arrangement was at risk with Daichi out in the open in front of their grandfather.

Mako kept reading as Daichi continued to talk in the letter in length about his experiences in Kaede, not even noticing the tiny man stood frozen on the sofa; scared to move in case his grandfather noticed him. Thinking fast, Rin shuffled forward on the seat towards her grandfather as if extremely interested in the contents. Daichi screamed as her legs came over him as she shuffled, her body stopping with her ass directly above him before slamming down onto his tiny form in an attempt to hide him.

Even a year into being Rin’s property, she rarely kept him near her panties knowingly. Daichi lay there smothered by her pink panties as she pressed her ass into the sofa to try and keep the troublesome boy still, causing her panties to sink into a wedgie slightly.

As Mako began to read the letter's conclusion as Daichi wished the two of them well, Daichi decided he’d try something. With all his strength, he tugged at the edge of Rin’s panties like pulling a curtain. They quickly gave way, unnoticed by Rin, and he threw himself into them. They slapped against her ass as he let go of the edge of them, causing himself to tumble into the centre of the back of her panties.

Feeling this intrusion, Rin jumped slightly and yelped as she didn’t expect it. Mako peered up at the girl confused, who put her hands into her face as if crying to cover for what had just happened. Mako smiled empathetically before extending his arm out to put his hand on hers for support.

“I hope you both are well. I love you both so much, Daichi”, Mako finished, before placing the letter down on the seat beside him. Shuffling closer to Rin, he put his arm around her and consoled her, “do not worry, young one. We all have to find ourselves eventually, Daichi is finding himself. He is happy and he is safe and that’s what matters”.

Keeping her hands in her face, Rin nodded to her grandfather’s words but all she could think about was Daichi’s intrusion. The smell within her panties was intoxicating to Daichi as he peered up at her asscheeks in front of him, he couldn’t understand why she had never opted to put him in her panties willingly. He didn’t want to be a pervert and ask but now he was here he couldn’t resist. Losing his willpower, he dived up towards her crack and began to dig himself between her cheeks. Rin could feel him weaseling himself deeper but could not do anything about it. Soon he reached her sensitive asshole and Rin’s face went a pale white with shock as she tried not to yelp out.

“Rin, you look unwell. I know it’s hard without your brother. Let us go get ice cream to make you feel better!” Mako suggested. Rin gulped as she digested his words, only responding with a slow nod as he linked her arm and led her out towards the front door. Her cheeks ground her tiny brother as she walked, which would’ve usually pushed him outwards as her sweat lubricated his body. However the tiny teen was driven, he kept shuffling his way deeper with each passing chance he got.

Mako walked through the busy streets towards their favourite ice cream store in the park that Daichi would meet Rin in after school. He knew she loved it there as he led the sheepish looking girl towards it. 

Rin couldn’t believe that Daichi had willingly gone in her butt. Did it not smell in there? She knew he had agreed to be her toy, essentially, forever. However, she didn’t realise how perverted he truly was. Anyone who would willingly climb in someone’s butt definitely had no second thoughts about their position. Was he genuinely going to be hers forever? How could she ever see him as her older brother now?

With the ice cream store in sight, just on the edge of the park, Mako looked at Rin and smiled happily at her as they walked. Rin smiled back, trying to mask the conflict she was feeling. On the one hand, it was still her brother and she had previously doubted he truly wished to be hers forever. However, this ordeal was telling as she felt him knocking at her backdoor. She hadn’t even wiped very well this morning, not expecting anyone near it. Yet he made no attempt to escape.

As they reached the ice cream store, Mako gestured for Rin to find somewhere nice to sit amongst the grass while he got their usual order. As Rin shuffled her way over to an empty space, she lowered herself slowly to the grassy ground and put all her weight onto her left cheek. Keeping her eyes on her unaware grandpa, she reached her hand under her ass and into her panties - gripping Daichi tightly with the tips of her fingers and plucking him out. 

Pulling Daichi out into the open, she was disgusted to find him damp from his own ejaculate in a euphoric, post-climax slump. “What are you doing, Daichi?!” she asked angrily, displeased by his intrusion. He was meant to be hers and yet she felt a little violated by him. He really was no longer the wise, older brother she had previously known him as. 

If this was what he really wanted then she was going to need to up the ante. No more mercy or care, no more just keeping him in her socks or under her armpit . If he wanted the life of a shrunken slave then he was going to get the life of a shrunken slave. She still loved him, but her respect for him had lessened significantly and she planned to show her love by giving him what he truly wanted in life: total domination without bounds.

Seeing Mako paying for the ice cream, she realised she was going to have to be quick. “Ergh, you’re all messy and I have nowhere for you”, Rin complained, unsure of where to put him as she looked across her body.

“Could you put me between your cheeks again?” Daichi asked, still feeling pleasure from his experience back there and feeling like he had the same older brother control over her as he had years ago.

“No you’re too tickly back there”, Rin explained. “But I guess…” she continued, Daichi’s eyes widened with glee as she moved him back towards her ass. She easily pulled her panties aside and slid him between her cheeks.

Daichi’s penis hardened immediately as he slid between her sweaty cheeks and right up against her asshole. However, his glee turned to horror as she didn’t stop there and he felt his shrunken body being forced against her elasticated pucker. It soon gave way to him and he felt his hands sinking into it. Daichi screamed out for her not to, “please Rin! No! No! Not in there! Anywhere but in there!” but his cries were soon muffled as he sank further in and her butthole began suckling on his head like a lollipop.

With his head now inside, with a little extra force, his shoulders soon followed. Daichi squirmed desperately, kicking his legs against her cheeks as they stuck out of her hole. Using the tips of her fingers, she easily slid them in until only his feet remained outside. With a clench of her sphincter muscles and a quiet pop, his feet were sucked in followed by the tips of Rin’s fingers for good measure. With Mako beginning to turn around with their ice cream, she pulled them out immediately and felt her hole close over him.

Smiling gleefully at his granddaughter waiting on the grass for him, Mako carried their ice cream over from the store and extended his arm out to pass Rin her cone. Rin accepted it thankfully and waited for her beloved grandpa to sit down with her. Mako could instantly tell that her mood had changed. “Feeling better?” he asked.

Rin simply replied, “Much better now, thank you Grandpa!”
