My Stepsister in Kyoto

"You took quite a while to take a bath." 

Mizuto stared at Yume and felt weird since he somehow felt that this situation was quite similar, but he also felt it was different. "Well, I want to relax a bit." 

"I cooked you something a bit normal, though." 

"It's okay. I like whatever you cook."

Yume smiled and was happy; then, she explained what she had cooked. Frankly, the dinner she cooked was quite simple, only rice, miso soup, grilled salmon, and a salad. It was a standard that people in this country usually cooked for dinner, but it was also because it was a standard that it was impossible to mess up. 

Even though Yume had learned how to cook from her mother, it didn't mean that everything could be perfect. 

Mizuto wasn't sure whether she was born on the strange star or just didn't have a talent for cooking, but sometimes, she messed up even a simple cooking process, so he was glad that she stuck on the simple dish, especially when Yuni, his stepmother, wasn't around. 

"Now that you mention it, where are Dad and Yuni-san?" 

Unlike Akatsuki's parents, who often stayed late, his father and Yuni hardly went home late and would go back as soon as possible. Well, frankly, his father's working schedule wasn't much different from Akatsuki's parents, who often stayed late or overnight in the office. If there was something that stopped him from doing so, it was because his father remarried. 

At this time, in this country, overtime work was already part of the culture. 

"Oh, they told me that they were going to stay in the office due to the storm." 

"Did they?" 

"Um, they just called me before." 

Mizuto looked outside and saw how heavy the rain was, which made it impossible for his father and Yuni to go home. 

"So... we're together for the night?" 

"Um." 

Yume lowered her head shyly, and Mizuto finally understood why he felt a sense of Deja Vu. 

Was this meant?

Mizuto fell in silence and then looked at Yume. As expected, she was beautiful and well-developed. The curves on her body were just right; her waist was thin, and her legs were perfect. The small, nerdy girl whom he had dated before had become such a charming girl. 

While he had sucked her innermost, and she even sucked his erection, they had never stepped on the last line. 

Partly because he was afraid that their parents might notice what they had done. 

However, now, their parents would stay out for the entire night, leaving the two alone in this house. 

Mizuto took a deep breath and said, "I see... how are they? Are they alright?" 

"Well, they told me that they were going to the nearby hotel together." 

The office where his father and Yuni worked was rather close, so it wasn't so surprising if the two decided to stay in the hotel for a night. 

Yet, it made him a little speechless as Mizuto was sure that his father and his stepmother were in the process of creating their future sibling. While this was something normal as they were adults, it was hard for him to imagine such a thing. Still, while he thought so, he realized how wrong his thought was and quickly put this thought away.

"By the way, how is your study?" 

"It's okay." 

They talked casually, but as expected, when there was a chance for them to climb the stairs of adulthood, Mizuto could tell that this girl was thinking all the perverted things. Frankly, he didn't really want to cross the line, but he could see the determination of this girl, and he was just a normal man. 

Facing such a charming girl, what could he do except accept her determination?

"Then, after dinner, do you want to study together with me in my room?" 

Yume was speechless by his words. 

Study together?

She was afraid that they would do more than that, but his choice of words made it easy for her to accept since she also felt conflicted about what they were about to do. While she had made up her mind, she didn't think that it would happen so fast. Nevertheless, she had expected this, though. 

"Okay." 

While he wanted to talk about something to ease this ambiguous atmosphere, in the end, he gave up and just continued to eat so he could finish his dinner as soon as possible. 

Yume was speechless, but she only smiled, thinking that he was cute. 

So, the dinner was quickly finished, and the two washed their dishes together before they returned to their own room. 

Still, after he returned to his room, the door of his room was knocked lightly, and Yume came in with her books. Even if what he had said was just an excuse, she still brought her books so it wouldn't be awkward. Nevertheless, as she entered, she thought about the memory of when they dated each other during the 2nd grade of middle school. 

At that time, she was ready to become a woman, but somehow, he was completely oblivious and ignored her advances, so in the end, the two of them only spent their time reading a book before she went home without doing anything. 

So, was tonight going to be different?

Or was he really asking her to study?

Probably so. 

So, in this case, should she make the first move?

Ugh... why had she always been the perverted one? 

Mizuto was hard to read, and it was impossible to guess what he thought, or did he have fun teasing her?

"What's wrong, Yume?" 

Watching his calm expression, Yume felt quite annoyed and pushed him directly, kissing his lips. This wasn't their first time to do this, and they had done it so many times inside his room, kissing, touching, sucking. 

They all had done it, taking each other's first time, without missing anything. 

This was probably something Yume could be proud of as she took all of his firsts, she thought. 

As they kissed each other, they got naked; Yume felt that her body was on fire, and her body only wished for him.

"Mizuto..." 

"Hmm?" 

"I love you. Be with me forever, okay?" 

Mizuto fell in silence for a while, then asked, "Do you like me so much?" Still, he knew that he had messed up since it was unnecessary for him to ask such a question, especially when everything was just in front of his eyes, and he was clear about what she felt toward him, so he just needed to say, "Yes," then the two would be together, yet he was still taken aback when he heard that she wanted to be with him forever. 

If it was at another time, she might roll her eyes or snort in disdain, but this time, she nodded firmly without looking away from him and made a confession, "I love you. I only want you. I don't want anyone else except you." Still, at this moment, she was also nervous, wondering how he felt toward her. 

Sometimes, she wondered whether she annoyed him and what he truly felt toward her as he had never expressed his feelings from his lips. 

His lips were trembling, but then, when he saw her nervous expression, he sighed inwardly and said, "I love you too, Yume." 

The moment those words fell, he hadn't even started to move, but she moved her waist hurriedly, wishing to put him into her innermost, which made him speechless since this girl was too perverted.

"Shh... let me handle this. Leave everything to me." 

Yes, as a man, how could he be pushed around?

Hearing his reassuring words and gentle voice, Yume stared at him in a daze as she nodded obediently. She closed her eyes and let her lips gently taken by him before she felt something enormous and hard slowly entering her body. This feeling... she was slightly overwhelmed at first, yet it didn't hurt. Instead, she felt a sensation that was far more delightful than his fingers, and as he slowly entered her innermost, he was stopped by a thin membrane, which showed the sign of her girlhood, yet he pierced it without hesitation, transforming her into a woman. 

Yume also felt this, yet she didn't feel any pain, only happiness, as she could feel that her inside was full of him. She looked at him with a happy smile, kissing his lips, which slowly grew stronger as they started their first adult activity.
