My Stepsister in Kyoto

Sighing in relief, Mizuto felt comfortable after he took a leak. Cleaning it with water and then washing his hands, he was ready to go back, but he had to say he didn't really want to return since the movie wasn't to his taste, and he wanted to check his system. Moreover, he was afraid of being entangled by Akatsuki as he was sure that he would accept her advance as long as she did it. 

It wasn't that Akatsuki was more charming than Yume, but each girl had their own charm points. 

However, he didn't know anything about Akatsuki, and he also didn't know her motive for doing something so bold with him. 

What about unconditional love?

Except for some parents who gave their every love to their children, he wasn't even sure whether such a love existed. 

Akatsuki was different from Yume, who had a previous relationship with him. He was Yume's first, but Akatsuki was different, so why?

Yet, he didn't bother to learn it since learning a woman's past was troublesome and a waste of time, especially when he didn't have much interest in Akatsuki except for her body. 

If there was one reason why she could be so aggressive that he could conclude, it would be lust. 

Yes, a lust. 

He was handsome, smart, and even had a nice body. 

Akatsuki must have felt lustful toward him!

Hmph! 

Even so, he wasn't such an easy guy! 

With that thought, he left the toilet, but he was stunned when he saw Akatsuki standing in front of the toilet door, and he felt like his life was about to be taken out. The scene before him somehow reminded him of the horror movie that they watched in the living room where the ghost would suddenly appear behind the character, then— 

*Gulp!*

Calming himself, he asked, "Do you need to use the toilet, Minami-san?" 

"Geez? Do you really think that I came to the toilet just because of that, Irido-kun?" Akatsuki asked him playfully. 

"Minami-san... I think that this is quite too early."

"Then, why didn't you push me away, Irido-kun." 

"You can't blame me, Minami-san. I am just an honest and a good boy."

"Honest, huh?" Akatsuki wanted to laugh. 

"But really... what's so good about me? We just met for... at least a few hours, right?" 

"To be exact, about seven hours and 56 minutes." 

"..." 

This girl was dangerous. 

Mizuto knew that this girl was bad news. 

"Geez, you don't need to feel scared about me. I just think that you are fun, that's all." 

"...is that so? Then, I will go back first. It isn't good if—" 

However, Akatsuki stopped him, holding his thigh as she looked up at him quietly. 

Mizuto took a deep breath and said, "Minami-san, do you know that even a docile animal can become a fierce beast when they are cornered?" 

"Then, can you show me how fierce this beast is, Irido-kun~?" 

After that, Akatsuki wasn't sure how she could return to Yume's side, but all she could remember was the docile, beautiful horse that she had seen in the wild had turned out to be a fierce stallion that couldn't be controlled. When she rode on him, he tried to throw her several times, yet she firmly tied her legs between his waist, holding his neck tightly so she wouldn't be thrown out as they had an intense confrontation with each other. Still, in the end, she was under his mercy. 

It wasn't until a moment later that he let her go and let her go back to Yume's side, but the shock brought by that confrontation still stunned her soul as she was unable to forget about the taste of that brutal exchange. 

Even if the movie continued, she was just in a daze until Yume's voice woke her up. 

"Huh? Where is Mizuto?" 

"Oh, right? Where is he?" 

Hearing Yume's confusion, Akatsuki also acted appropriately. Still, she was stunned when she saw the movie had ended and didn't expect that she would have such a long stupor. Watching Yume, who looked around Mizuto like a lost puppy, she sighed helplessly, thinking that if Yume didn't grow up, then she was afraid Yume would be eaten by Mizuto without a single bone or flesh remaining. 

---

Inside his room, Mizuto changed his uniform into his casual t-shirt and shorts since Akatsuki's scent remained on his uniform. Still, someone suddenly opened the door of his room. 

"Mizuto, are you here?" 

"...." 

His lips twitched when he saw Yume, who opened his door casually without knocking on it. He wondered whether this was deliberately done or if this woman had gotten so snug living in his room that she thought this was also her room. 

While he didn't mind her actions since even if he was naked, he didn't mind being seen, the problem was that Yume wasn't alone since Akatsuki also came along. 

Fortunately, it was only his upper body that was seen, yet it still had an impact on the two girls. They were like two teenage boys who just happened to see the beautiful big sister in their neighborhood, taking off her clothes, showing their bare white cleavage. 

At this moment, they couldn't take away their eyes from his body. 

Masculine and strong. 

This was probably the most appropriate description of his body. 

He had a broad chest, well-sculpted muscles that showed every line of his body, and a v-shaped cut in the abs. 

He might appear slender when he wore his clothes, but he was amazing when he was naked. 

Yume had seen his body several times, but she knew that she couldn't get enough of it and wished to touch it. Still, she suddenly realized something and then looked at Akatsuki, who was in a daze, causing her to feel a strong sense of possessiveness as she wanted to be the only one who saw this body. 

"Akatsuki-san, don't look!" 

"Ah!" 

Akatsuki was startled when Yume pushed her. 

"Why didn't you wear your clothes?!" Yume quickly asked after she pushed Akatsuki away. She didn't close the door fully but poked her head inside as she questioned him. 

Watching Yume like this, he felt that this girl was quite silly. "Why didn't you knock on my room when you entered?" 

"...." 

That single question was enough to defeat the strong Yume. 

"So-Sorry... I-I will knock on the door next time." 

No, next time, she wasn't going to bring anyone with her, so that way, she could only see this scenery alone. 

"By the way, you are not going to close the door?" 

"I will wait for you. We're going to play a game after this." Saying those words, Yume didn't have any intention to close the door and kept watching him until he put on his clothes. 

"....." 

Mizuto thought that his stepsister was such a horny girl. 

---

While there was a little incident, the three of them returned to the living room and played a game together. After they watched the movie, the food in their stomachs had already been digested, and they could move around without worry, so due to this, they decided to choose a dance game. 

Even though there were only two sticks, Mizuto could use his smartphone as an extra stick after he downloaded an app. Still, he didn't do that and just sat on the sofa, watching the two girls make various movements following the movement of the game on the screen.

"Come on, Yume-chan! You will need to move your body more!" 

"Ugh... it's difficult." 

As the two moved around, their short skirts sometimes jumped up, down, or moved from left to right. Sometimes, he would catch a glimpse of their white and pink panties. While Yume was oblivious as she was so engrossed in the game and had limited stamina, Akatsuki's physical ability was unexpectedly good. She might be small, but her motor skills and flexibility were rather good. Moreover, she might feel a bit grudged towards Yume as Yume pushed her before, so in this game, she didn't show mercy toward Yume, especially when she often gave a fan service to Mizuto, who sat on the sofa by offering a glimpse of her panties from time to time. 

"....." Mizuto. 

Nevertheless, the three of them enjoyed their time until the voice of their parents came. 

"Yume, Mizuto-kun, we have gone home." 

"We have bought a cake." 

Mineaki and Yuni came home quite early, and at the same time, they wished to celebrate their admission. 

"Mom, Mineaki-ojiisan." Yume greeted the two awkwardly after they saw him dancing in the living room. 

While the two laughed at Yume and Mizuto, who played together, they noticed the small Akatsuki. 

"Oh, this is?" 

"Hello, my name is Akatsuki Minami. I am their classmate." 

"Oh! It's Yume's friend! Do you want to have dinner with us?" Yuni was excited when she saw her daughter bring a friend together. 

Hearing this invitation, Akatsuki hesitated, then thought for a moment and glanced at Mizuto. 

"If you want to stay, then stay." Mizuto never thought much since, in his mind, the merrier, the better. 

"Well, that's true." Yume also didn't have the heart to send Akatsuki out, so she also agreed. 

"Th-Then, I will join you..." 

While nervous, Akatsuki was so happy at that moment.

The five of them had dinner together, talking about what was happening in the school and how Akatsuki and Yume knew each other before talking about how popular Mizuto was. 

"Oh, there are a lot of girls who are interested in Mizuto-kun?" Yuni was dumbfounded before glancing in her daughter's direction. 

"Maybe Mizuto will bring a girlfriend home later," Mineaki said with a smile. 

Only his voice made all of them fall in silence. 

Mizuto looked at his father helplessly, wondering whether Mineaki wanted to lose his son so soon. 

Nevertheless, the dinner was spent in good time for the five of them; only no one knew what they thought inside, especially Yume, who heard Mineaki's words. 

"It's already so late. I will go back first. Thank you for the dinner, Yuni-obaasan, Irido-ojiisan. It's delicious." 

Akatsuki was polite and like a good girl who never did anything wrong. 

"Really? It isn't that much, though. If I know that you are coming, I might prepare something better." 

"No, no. It's me who is rude to come without a notice." 

"You don't need to think too much, you know? I am happy that Yume has a friend in the school." 

"Yume-chan is cute. I am sure that she will make a lot of friends." 

"....." 

Yume stared at Akatsuki in a complex mood since she realized how amazing the outgoing person truly was. 

"Then, I excuse myself first. Once again, thank you for the dinner." 

"Ah, do you need someone to send you off?" Yuni looked at Mizuto and asked, "Mizuto-kun, can you send Minami-san back?" 

Mizuto glanced at Yume and asked, "Do you want to go with us, Yume?" He didn't refuse to send Akatsuki back, but he decided to bring Yume with him. 

Somehow, this question brought warmth to Yume's heart, and she nodded. "Okay." 

Akatsuki didn't say anything, only smiled. 

As the three left the house, they walked to the train station, which Akatsuki usually took to go home. 

"Ah, it's okay for you to send me here. Thank you." Akatsuki said when they were about to arrive at the train station. 

"Then, we will go back first, Minami-san." 

"See you tomorrow, Akatsuki-san." 

Leaving Akatsuki, Mizuto and Yume returned to their house as they knew Akatsuki would be okay. 

Still, Akatsuki didn't enter the train station and just stood quiet in the dark, watching the two. Touching her lips, thinking about what had happened before, she just kept standing there in silence even if she couldn't see their figures anymore. 

Meanwhile, Yume glanced at Mizuto from time to time, wanting to say something, but when he held her hand, she showed relief and a happy smile. 

"I am a bit scared of the dark. Hold my hand, Onee-chan." 

"Hmph! What a helpless little brother... But leave it to your Onee-chan~!" 

Watching her smug expression and somehow lustful expression, who wished to eat him whole on Yume's face, Mizuto sighed helplessly, wondering why there were so many horny women around him.

By the way, for Nami Ootake, you don't need to think she is, like, in the original, a warrior with hundreds of experiences since I definitely won't make her like that. I had said before that her origin was going to be different, and she was only with her husband till she met the protagonist. 

Her origin might be a little strange or even unfamiliar, as it is rare for someone to have such an origin, but I won't make her a hardened warrior, okay?

Oh, right! 

There is only one chapter today.

Lastly, Happy New Year!
