Stay alive!

"Are you going to date my daughter with another woman at the same time?" Kiriko asked Isao with a blank expression. 

After Isao showed his love to Rei and Saeko, while he made the two believe how much he loved them and how much they meant to him, it was naturally impossible for him to make everyone believe him, especially Rei's mother, who happened to peek at them, watching her daughter had a threesome with Saeko and Isao. 

Watching this scoundrel deceive her daughter and another innocent young woman, Kiriko ground her teeth in annoyance. Yet she couldn't stop them since she knew that they had fallen for him, so no matter what she said, it would be useless. 

However, more importantly, she could tell that Isao would genuinely take care of them, so even if she was angry, she didn't have much of an objection if they wished to be with Isao at the same time. 

However, Isao was a bad guy! 

A scoundrel who also slept with her, the mother of his girlfriend! 

While it was true that Kiriko was also at fault since she let a moment of weakness swallow her and let this bastard sleep with her, making her unable to forget that moment they shared in that empty room, she truly wanted to see how much he cared about her daughter. 

Kiriko didn't want Isao to play with her daughter's feelings! 

So, while it was quite shameful, she kept watching Isao play with the bodies of Rei and Saeko until he let them fall asleep and walked out of the room so she could talk with him. 

"I am sorry." 

Isao apologized sincerely and even bowed his head. "I know that I might have disappointed you since I can't only be your daughter alone, but believe me." He raised his head and gazed into Kiriko's eyes with eyes of determination. "I have never thought of your daughter as a plaything, and I will treasure her. I know that my words might not be able to convince you, especially when I have another woman other than your daughter, but once again, please believe me and give me a chance to show that I can love your daughter." 

Isao knew that he was a bastard for asking Rei's mother to give him permission to date her daughter with another woman, too. Moreover, he even slept with Kiriko, which made his words weak and hard to believe, yet he was serious. He never thought of playing with women anymore, especially when Rei and Saeko were good women. They were worthy of being treasured and being held by him forever. 

"....." 

Even though his words were shameless, Kiriko could see Isao told the truth, and he was going to treasure her daughter. Still, even if he didn't treasure her, she couldn't do anything, especially when her daughter was already being held by him so many times, and probably, her daughter's body couldn't be satisfied with another man, especially when Isao was just too skillful and also had a generous size. 

So, she knew that she had no choice but to believe in him.

Believe in the words of this motherfucker! 

While she was helpless, she said, "I will hold those words, Isao-kun. If you lie to me, even if Rei loves you so much, I will separate you!" 

"I will. You can hold my vow here." Isao nodded and didn't seem afraid of Kiriko's intimidation. Instead, he felt that she had become more charming, especially the gap when she moaned lewdly, and her cold face was just too unbearable. 

Kiriko probably noticed the change in his gaze, which made her body hot and her face reddened in embarrassment. 

The two couldn't possibly forget what they had done previously, and it was still vivid in their minds. 

Still, Isao was a good boy, so he tried to erase this awkwardness. "Kiriko-san, I need to go to the dam to check the energy plant, so please take care of Rei-senpai." 

"...are you going to go out again?" 

When Kiriko heard that Isao was going out once again, she became worried. 

"Yes." Isao nodded firmly. "We have lost electricity, and there are too many corpses in this place. In the future, those corpses might even become a source of disease, so we have to leave. Moreover, I am the only one who understands about the energy plant, so I have to go." 

"...." 

Kiriko stared at Isao in melancholy and sadness, thinking that he was like a young man who had to go to war to protect his homeland and family. While she wanted to do something, she knew that she couldn't do anything except protect Rei and comfort Isao. 

"Be careful. Be safe. You have to go back since you have a lot of people waiting for you." 

"I will." Isao nodded and never looked away from Kiriko, but suddenly, he hesitated and said, "...I know that it might be rude to ask you this, but..." 

"It's fine. Ask me anything," Kiriko quickly said. 

"Can... can I hug you?" 

Kiriko blinked her eyes, and once again, a cute blush covered her beautiful face. 

"I know that a lot of things happened between us, but I am glad that I met you, Kiriko-san." 

"Geez..." Kiriko let out a helpless sigh, then pulled him into her embrace. "Go back safely, okay?" 

"Um." 

Isao hesitated, but in the end, he hugged Kiriko in his arms and, once again, felt the softness and warmth of the body of this 37-year-old housewife. 

Kiriko was a little embarrassed, but she knew that while Isao appeared strong, he was just a young man. Moreover, everyone relied on him, even though he was just a high school student. When she thought about how much burden he had to bear, she couldn't help but feel empathetic, wondering how he felt at that moment. 

Only—

"...sorry." 

As Isao apologized, Kiriko looked up at him with a helpless gaze as she could feel his erection on her plump thighs and smooth belly, thinking that this boy was too healthy, right? 

Unlike Kiriko, it had been a while since Isao hugged Kiriko, so he couldn't help it, especially when he had many older lovers in the world of "Kimetsu no Yaiba." 

When he hugged Kiriko, he couldn't help but think of Kie, who had become a mother of his children. Even though Kie had given birth to many children, her body was still taut and moist, and Kiriko reminded him of Kie, whom he missed even though he had just stayed in this world for a few days. 

Yet, even if it was only for a few days, Isao had to say his experience in this world was unbelievable. 

Still, Kiriko wasn't Kie, and she was also Rei's mother, so Isao knew that he had to hold this feeling and ask Kyoko or Yuriko for comfort later. 

However, even though he had tried to hold this feeling, the familiar feeling suddenly enveloped his erection. As he looked down, he saw Kiriko's hand that moved against his erection affectionately, lustfully, yet there was this a trace of helplessness on her face. 

"L-Last time! This is only the last time! After this, you have to forget everything!" 

Kiriko made a declaration with a cute blush on her face. 

"Yes!" 

Isao nodded obediently before taking Kiriko to the empty room, ready to hold her for the "last time" today. 

However, as he had made a promise to Kiriko, he knew that he had to stay alive. 

Even if there was a danger that he might encounter during his trip to the dam, he had to return to everyone since they were waiting for him. 

Fixing his pants, he went out after he put Kiriko in the middle of Rei and Saeko inside his room. 

It was just that Isao happened to meet Naomi. 

"Ah, Isao-kun..." Naomi looked at him shyly. 

Isao took a deep breath and made up his mind to stay alive no matter what!
