My Stepsister in Kyoto

"Are you really a high school student?" 

The moment Rinko Akashigata spoke, Mizuto stopped moving. He looked at her, there in his arms, her small-boned, shapely body nearly folded in two in the shadow of his broad back. In the glow of the bedside lamp, he could see frown lines between her brows. Although shut, her eyelids fluttered as if she were weeping. She was at the very point of orgasm, body and soul soaring high, shedding all restraint. 

She had cried out during sex with him earlier: "Nooo," or "I am going to come," or even softly, "Help..." The words tumbled out just to the point where she felt she'd burst. Yet never before had she spoken of fear. He held her tight, saying nothing, while her writhing turned into rippling shudders and then to stillness. She had climaxed. 

Before their lovemaking, she appeared fairly reticent, as seemed only appropriate to another man's wife. Now, as if embarrassed by her sheer abandon, she lay on her side in the fetal position, knees drawn up, the sheet covering her body from the breasts to below the hips. 

Even worse, the man who had made her this way was just about the same age as her daughter. 

Yes, she was the woman whom he had met on the bus in the morning, and when he went home from Yuu's house, he came to visit her, which she welcomed and then led into their intimate exchange. 

Like she had told him before, her house was empty, and there was only him and her, which made them able to enjoy their lovemaking fully. 

Due to this, her level had risen to Level 35. 

Was it due to his kiss with Yuu?

Or was it due to his lovemaking with Rinko?

Mizuto wasn't sure, or maybe both. Still, unlike when he had a lovemaking with Nami and could level up to the max level directly, he couldn't do so with Rinko, which made him helpless. 

Still, he put his chin on her round, smooth shoulder and asked, "What do you mean?"

"It's just... you just know how to make women feel good." 

"Is it bad?" 

"...it's just I am scared." 

"Scared?" 

"You are dangerous." Rinko let out a sexy sigh as her body recalled what they had done previously. Still, she wasn't young anymore, so her stamina wasn't as good as when she was young. Nevertheless, in exchange for her youth, she gained a skill and an experience that had never been shown to a young woman. However, in front of this young man, everything was meaningless. 

In his embrace, she became a lone, small woman. A single boat that sailed on the stormy waves and desperately hung on until it saw the land. 

It was said that youth only knew how to use their physical ability and stamina, and they only cared about their own comforts. It should be something like that, but she didn't mind since he was handsome and she needed someone to make her forget about many things, so she didn't mind going wild for a day. 

Yet, unexpectedly, she was wrong. In the beginning, she only wished to make this relationship one time, thinking that it was just some mistake, but at this moment, she was afraid that knowing this pleasure, she couldn't leave him. 

However, when she thought about their age difference and how young he was, she knew that she needed to throw her fantasy away. 

"You are the one who makes me dangerous." 

"...it's my fault?"

Mizuto kissed the back of her ear and softly said, "You are so charming, Akashigata-san." 

Rinko sighed helplessly since she wasn't young anymore, so she wasn't naive enough to fall for his flirt, yet no matter how mature the woman was, they would feel comfortable by the sincere praise of the man, especially those whom they had an interest in. 

"Can I borrow your bath?" 

"You want to take a bath?" 

"Um, it's a bit hard to explain to my parents if I have your scent on all parts of my body." 

Similar to Nami, the scent of a mature woman like Rinko lingered on his body for so long, so he wished to wash them. 

"Do you have strict parents?" 

"I don't, but it is hard for me to explain that I sleep with someone's wife." 

"...you are right." 

"Though, it should be alright if I say that this is the scent of my girlfriend." 

Rinko laughed and said, "I should be as old as your mother, right?" 

"I don't think so. You look so young, Akashigata-san. If we walk together, someone might mistake you for my older sister." 

"You sure know how to talk sweet." Rinko pinched his cheek with a laugh as she turned to look at him. "Then, go ahead. I will rest for a while. You can go back immediately if you want." 

"Okay." Mizuto was about to leave, but then he asked, "Do you want to take a bath together?" 

"...I am not young anymore. I can't do it. I am completely exhausted." 

Usually, it was only an old man with many experiences that could have Mizuto's skill, but when one became old, they lacked a physical ability. 

However, Mizuto, while he was young, had the experience of those old masters, yet with the body of the youth. 

The combination of the two was simply destructive for Rinko, a helpless housewife at 37. 

Yet, what was even more frightening was his size, hardness, and stamina. She was startled at first as it was her first time to see something so enormous, yet soon, she felt so comfortable with it, and probably she might not be able to feel satisfied with others anymore as the shape of her innermost part was changed by him. 

"While I don't think that you are old, I know that I can't control myself if I go with you, so you are right. It might be better if you don't come." 

"...okay, then, only once." 

Smiling, he held her, carrying her in his arms as they played in the bathroom before she was completely exhausted. Naturally, he made sure for her to see him, leaving the house before she returned to her bed, sleeping so soundly. 

At the same time, he thought that she was too careless since they were practically strangers, yet she let him into her house. 

What if he's a bad guy?

He might have stolen everything inside her house, but strange enough, even though her house was quite nice, there was a lack of furniture, as if some of them had been sold due to a certain reason. Still, if the problem was really what he had imagined, then he could help her, yet they only met once, so he didn't think it was appropriate for him to be direct.

Moreover, he felt that it was only one time, and he didn't think that Rinko would invite him anymore, especially when they didn't exchange contact info. They also were neighbors, and this was what made this matter dangerous since he might be seen by others when he walked to Rinko's house. Lastly, while Rinko was charming, he didn't lack a woman. Instead of doing something dangerous, it was better to do it in a light manner since there was nothing good about being serious with someone's wife unless that wife sought after him. 

However, he was glad to meet her since that way, his level had risen a lot. 

Looking at the many skill points in his system, he maxed out the "Gaze," the "Pleasure," and "Stamina" skills, leaving five points left, before deciding to distribute them to "Smile" and "Charm" evenly. 

He knew that his choice might be weird, but he was afraid if he was too handsome, he would be attacked by women sooner or later. 

If the women were beautiful and healthy, he was okay, but if the women weren't good and even sick, then, even if he knew that it was cruel, he would use the "Brainwash" skill. 

At the same time, he also thought that he needed a "Job" that could help him to fight.

Still, he realized that he didn't have much improvement in his physical ability even though he had chosen his 3rd job and maxed out our two jobs. Instead, he felt that he was even healthier, and his regeneration was quite absurd. 

Usually, he would be fine with letting out twice a day. While he could do more, he knew that it wasn't healthy to do it too many times, so he limited himself when he was with Yume, but as his level on the system grew, and he chose more jobs, it made him like those characters on the hentai manga that could let out an infinite amount of juice. He knew that such a thing was a fantasy, but it happened to him, which made him speechless. 

Still, he liked the "Stamina" skill since he could feel that he was brimming with energy. 

It was said that Napoleon Bonaparte slept about four hours a night to improve his genius movement.

Somehow, if he wished to, Mizuto could copy it now or do even better than Napoleon.

After all, a day was only 24 hours, and it was so short when there were many things that he wished to do. 

Still, as he walked home, a figure was also walking toward Rinko's house, and he would be glad that he didn't stay any longer. 

This figure didn't think too much about Mizuto, but when she saw his eyes when he made a turn, she stopped and gasped, standing in a place petrified.
