Taro Yamada entered his house and closed the front door behind him. He had just walked home from school accompanied by his close friend, Osana Najimi, as usual, and she continued on to her own home as he entered his. He went over to the table and sat down and started getting his homework done, which he thankfully didn't have very much of today, which meant he would have a lot of time to relax afterwards.

He currently had the house all to himself. His parents wouldn't be home from work until later that evening, and his younger sister, Hanako, still wasn't home because she went to a different school from him in a neighboring city, so her commute between home and school was much longer. She would probably be home in less than an hour, and she would absolutely want to spend time with him and chat with him, but in the meantime he worked on his homework while basking in the peaceful and quiet solitude.

It's not that he didn't enjoy social interactions - he enjoyed and valued them very much, in fact - but he also preferred to spend a lot of time by himself. For example, at school, when he wasn't in class, he would often sit at the fountain in the plaza and read (a major hobby of his) while enjoying the atmosphere of the plaza, the trees, and the soothing sound of the fountain.

He was almost finished with his homework when Hanako came in through the front door.

"Hey Taro, are you home?" she called out brightly and cheerfully as usual.

"Hi Hanako, I'm over here," called Taro from the table, as he felt the usual mix of annoyance and joy he felt when she got home.

She came over to the table and looked at him with a bright smile on her face. "Hey big brother," she said brightly, skipping happily over to the table and sitting beside him. "How was your day?"

He returned her smile, both amused and a bit annoyed at her childish attitude and giddiness. She was only two years younger than him, but she sometimes acted as if she were even younger.

"It was good," he replied, "but if you don't mind, I would like to finish my homework first, and I'm almost done. Then we can talk."

She nodded and scooted her chair right up against him, put her arm around his arm, and rested her head on his shoulder. He couldn't help but smile a bit at this. As childish and slightly annoying as she was, he enjoyed, appreciated, and savored her affection for him. Within a few minutes, he finished his homework and was finally ready to talk to Hanako about his day ("Tell me all about it!" she said excitedly), and they began chatting.

They used to spend a lot more time together when they were younger. In fact, they used to frequently play together along with Osana back then. But as they grew older, while he and Hanako remained close and maintained a good relationship, they spent less time together. He grew more independent, and so did she to an extent, but she also remained very clingy and over-dependent on him, and was very frequently looking to spend time with him and trying to get his attention, sometimes to an annoying degree, even when he wanted to be left alone.

Sometimes he would step up a bit and push her away a bit in those instances, but a lot of the time he didn't because he didn't like to make her sad, let alone make her cry, and therefore he didn't have the heart to push her away. Also, admittedly, a part of him did find her clinginess a bit adorable, annoying as it was.

After a few minutes of talking to each other about their day, Hanako announced that she had to pee pretty bad, and she stood up. But instead of walking to the toilet, she just stood there and looked at Taro, a slight smile forming on her face.

"Yes?" he asked.

"Would you like to have a peeing contest?" asked Hanako.

"Huh?" replied Taro.

"Yeah, in the backyard," said Hanako. "Come on, we've done it before once."

"Years ago, when we were younger," said Taro. "It seems a bit silly and childish now."

"Aw," said Hanako, looking disappointed, "I was hoping you'd be willing to. I was looking forward to it on the way home."

"Well, I'm sorry, but I'm not interested," replied Taro, feeling a bit bad.

She smiled at him as she turned to walk away, but the disappointment was still evident on her face. He heard her dejectedly mumble,

"I held it all in this long for nothing."

He felt a bit guilty. Even though he did find the idea dumb and childish, he could tell she really wanted to do this, and he felt bad making her sad. Not to mention that in the last week or so, he had been spending even less time than the fairly limited time he usually spent with her these days, since he had been a bit more focused on school work, as well as invested in the book he was currently reading (which was ironically given to him by Hanako). And honestly, there was a part of him that found the idea of a peeing contest with his sister a bit fun and exciting. A part of him that did miss the older, younger times, and did want to spend more time with her again. Not to mention he honestly did have to pee right now himself (although not nearly as badly as she did). So he decided that he would agree to her request.

"Hanako, wait," he said. She turned around to face him, and he stood up.

"I'll do it," he said. "We can have a peeing contest if you like."

"Really?" she said, her face brightening up, making his heart melt a little.

He nodded. "Yeah. Honestly, I have to pee to, so let's do it."

"Yes!" she said excitedly, and ran over to him and hugged him. He staggered a bit for a moment from the force of her running into him, and he reciprocated her hug. A second later they pulled apart, and together they went out the back door and into the backyard.

As they entered the yard, he couldn't help but smile a bit at the memories of himself, Hanako, and Osana playing together in this yard when they were younger. He and Hanako found a good spot in the yard to have their little contest, and they stood side-by-side.

She pulled up her miniskirt, but before she could grab her panties to pull them down, Taro told her to wait, and he quickly checked to make sure there was nobody around to see them. The yard was surrounded by fairly high walls, but they could still potentially be seen from the second story of the two neighboring houses. But he didn't see anybody in the windows of those houses, and he knew that their occupants never got home until later, so they were safe to do this.

"Alright, we're safe," he said, satisfied. "No one's going to see us."

And with that, he unzipped his fly, and she pulled down her panties and pulled one leg out of them, and let them hang around her other leg; and then she squatted down with her legs spread.

"Ready. Set. Go!" said Hanako.

And with that, they let loose and began peeing, thus beginning the contest.

As they relieved themselves together, they glanced over at each other, and shared a smile. He could see the childishly giddy yet genuine joy in her face, glad she was happy, especially knowing that he was making her happy by sharing this moment with her. He even found himself enjoying this a bit more than he thought he would, and was getting slightly invested. Also, a little bit of nostalgia for their younger days was washing over him.

They then looked back down at each other's pee streams. Her stream was a bit stronger and thicker than it would normally be (since she really had to go), but it still didn't reach quite as far as his stream. He could tell that she was a bit disappointed by this (with a slightly playful pout on her face), and he found it a bit cute, and a part of him even felt a little bad for her. But he wasn't about to just give up the competition.

But then she started pushing harder, and spread her legs a bit wider, and leaned back slightly to make her stream go even farther, which it did. It was was reaching even farther than his stream now. This spurred Taro, who was now even more surprisingly invested at this point, to try and make his stream go farther as well. But he still couldn't get it to go quite as far as his sister's stream was now going, let alone farther.

He could tell from the look on her face that she was really straining and pushing to make her stream go as far as it was now going. He found this rather cute and amusing, and he couldn't help but smile and chuckle slightly.

"Hey, don't laugh at me," she whined, slightly indignantly.

"Hey, whose idea was this again?" he said with a slight smirk.

She let out a cute little indignant groan, and then said, "Well, it doesn't even matter, because I'm winning now." And she shot him a slight smirk. He smiled and rolled his eyes in response.

Taro finished peeing and zipped his fly back up, but Hanako continued peeing for a few more seconds. She finally finished with a few final small spurts. After her very last spurt trickled down and off of her butt, she smiled up at her brother and brightly declared, "I win!"

He smiled back at her and said, "Yes you did, fair and square. Great job!"

She smiled in thanks and stood back up.

"Aren't you going to put your panties back on?" asked Taro.

"Huh?" she said, and looked down and realized that her panties were still hanging around her ankle. "Oh!"

She quickly bent down and, slightly clumsily, put her other leg into her panties and pulled them back up. Taro couldn't help but find this a bit cute and amusing, and he smiled, rolled his eyes, shook his head, and let out a soft chuckle.

"Maybe you do need me to be with you all the time, after all," said Taro.

She looked at him in response with a hint of indignance mixed with a smile of affection.

"Anyway, I enjoyed that," said Taro. "Thanks for asking me to do that with you."

"Yeah, that was fun!" she said brightly. "Just like old times, huh?" she added, slightly playfully.

"Yeah, it was great to do something like this with you again," he said sincerely.

He gave her a gentle, affectionate headpat, which she happily leaned into. Then they turned and walked back towards the house together.

"We should do that again sometime," said Hanako.

"I wouldn't want to make a regular habit out of it," said Taro, "but I wouldn't mind doing this once in a while."

She smiled warmly in response. They went into the house and spent the rest of the day together. She did her homework (with a little assistance from Taro here and there), and then they spent the rest of the evening relaxing, having fun, and spending quality time together, and savoring every bit of it.
