The joy of a woman

Shinobu felt conflicted. 

Whether it was all due to her big sister or Isao. 

The two had been on her mind since the incident. 

Unlike the others who underestimated Isao, Shinobu knew how powerful Isao was, especially when she saw Isao's body. Even more so with her knowledge regarding medicine, so while it might be hard to accept if somehow Isao had a relationship with her big sister, it wasn't like she couldn't accept it since if it wasn't because of him, she would lose her sister. 

So, if they were really married, then she could only support them. 

However, his attitude and act disappointed and saddened her, especially when he refused the invitation to Kagaya to join the Demon Slayer Corps. 

The disappointment didn't come from how Isao refused Kagaya. 

Instead, she was disappointed and saddened, thinking about what would happen after Isao left. 

While there was no rule that those who were part of the Demon Slayer Corps couldn't be with those who didn't join, as Hashira and the head of the Butterly House, there was no doubt Kanae would be busy. 

By then, would they be able to meet? 

Yet, at the same time, she also felt this was better since, unlike her and her big sister, Isao didn't have a grudge or a vengeance that made him wish to use his life to eradicate a demon.

Living a normal life like others might be the best way for him, she thought. 

At the same time, she was also thinking that it might be better for Kanae to follow Isao. 

Yes, she wished for her big sister's happiness, and she thought that Kanae should chase after her happiness instead of staying in the Demon Slayer Corps. 

For someone as gentle as her big sister, while it was too cheap for Isao to get Kanae, Shinobu knew that this was for the best. 

So, tonight, when everyone fell asleep, she decided to have a heart-to-heart conversation with her big sister. However, when she was about to reach her big sister's room, unexpectedly, she met Kagaya's wife, Amane. 

"Amane-sama? What are you doing here?" 

"I wish to talk with Kanae-sama," Amane said softly and calmly. 

Still, unlike her husband, who called their first name freely as if nothing, she called the members of Hashira with the "-sama" suffix, thinking that her position was below them. 

"Oh, wait a moment. Let me check whether Kanae-neesan is sleeping or not." 

Shinobu didn't think Amane's visit was weird; she only thought that there might be something that Amane really needed to ask, so she quickly changed her attitude, ready to wake Kanae in case she was sleeping. After all, no matter what, if Amane came to visit Kanae at this moment, there must be an important question that Amane wanted to ask her big sister. 

Yet, what Shinobu didn't know about Amane's purpose in visiting Kanae definitely wasn't pure.

The task given by her husband was definitely something that Amane had to do. Even if Isao had rejected their invitation to join the Demon Slayer Corps, there was no way for them to give up. 

Still, if a direct invitation couldn't be done, what if Kanae was the one who invited him?

Kagaya saw the close relationship between Isao and Kanae, and he thought that this could be a turning point. 

Sending his wife to Kanae and asking her to invite Isao was definitely an effective move. 

Still, didn't it mean that they were using Kanae? 

Yet, there was nothing wrong with it since everything was to eradicate the demon from this world! 

"Nee-sama, are you sleeping?" Shinobu knocked on the sliding door while asking this question. She waited for a while, but she didn't hear an answer, so she opened the door quietly. However, unexpectedly, Kanae was nowhere to be seen. "Huh?" 

Amane, who was standing behind Shinobu, also didn't see Kanae inside her room. 

"Where is Nee-san?" 

While Shinobu was confused, Amane said, "Is she in Iinuma-sama's room?" 

"Huh?!" Shinobu was dumbfounded. "There is no way!" It was definitely impossible for Kanae and Isao to be in the same room. The two of them were a single man and a woman. It was inappropriate for them to stay in the room during the night at the same time. Moreover, they hadn't married yet, so there was no way for Kanae to be in Isao's room. 

"How about we check his room?" However, Amane was still calm and just said those words. 

"..." Shinobu fell in silence, and then she reluctantly agreed. "She definitely won't be in that guy's room!" It was definitely impossible, and she didn't believe it! 

Yet, the closer she was to his room, the more nervous she became. While she wanted to deny it, the chance of her big sister being inside Isao's room wasn't zero, and if it was true, what were they doing inside the room at night? 

'No, they might have some discussions about a demon and a breathing style!" 

Shinobu was optimistic and thought the reason Isao and Kanae were in the same room at night was that they might be discussing a demon, a Demon Slayer Corps, and a breathing style. At the same time, she also thought that Kanae might try to invite him to join the Demon Slayer Corps. 

The night was quiet, but Shinobu's heart was hardly quiet, and it beat so fast that she wanted to run away. However, her body couldn't listen to her heart, and deep inside, a certain possibility crossed her mind, a possibility that she didn't want to think was possible. 

"Hnh~!" 

It was quiet and almost inaudible, but a light whimper was heard. 

Shinobu and Amane stopped their steps as they looked at each other. Hesitating, they decided to walk closer, and the sweet whimpers became clearer in their ears. However, when they were about to get closer to his room, Shinobu suddenly said, "Let's check his room first to see whether he is sleeping or not. It might not be good if we wake him up." Even if she knew that Isao didn't sleep, she still said those words. 

Amane nodded quietly. "How are we going to check?" 

"Come here, Amane-sama." 

They went to the next room where Isao stayed. 

Amane didn't say anything, but she watched Shinobu open the wardrobe and then slip inside. Hesitating, she also decided to follow through and entered the wardrobe after she closed the door of the room. 

The room turned dark, and no light ever entered it, but even so, Amane walked toward the wardrobe precisely and saw Shinobu, who was all four, as she pressed her eyes toward a small hole in the wall. 

"What's wrong?" 

This question stunned Shinobu, making her silly, but she gritted her teeth so she could not make a voice. Her face flushed red, and her expression was mixed with a variety of emotions.

Excitement, anger, helplessness, and many other emotions jumbled within her. 

Yet, there was no doubt her heart was beating so fast, her body was so hot, and she squeezed her small thighs tightly. At the same time, she also wasn't sure how to describe this situation, and frankly, she wished for Amane to leave, but, during Shinobu's hesitation, Amane also moved her head forward toward a small hole in the wall. 

"Amane-sama!" 

Shinobu said quietly, almost hissing, but it was too late. She couldn't stop Amane, and Amane saw what Isao and Kanae did inside the room. 

Amane's eyes widened, and she was clearly dumbfounded by the obscene situation before her eyes.

Like a dog, they mated while Kanae was all four, and Isao pounded her from behind. The two did something so dirty and lewd. 

Yet, Amane couldn't look away, especially when she saw the joy on Kanae's face. 

Unlike the gentle and reliable Hashira that everyone trusted, Kanae's face was like a whore that opened her legs for a beast. His large erection plunged deeply into her hole, and the vulgar sound kept echoing inside the room. 

However, this situation surprised her. 

As a married woman, Amane shouldn't be surprised or even blushing since she had done it with her husband, but whether it was for her or her husband, the act of sex was nothing but an act for one to create children. It was nothing more and nothing less. Moreover, with how frail her husband's body was, how could he even have the energy to please her on the bed? 

So, instead of being disgusted by Isao and Kanae, Amane was entranced, feeling her entire body was hot and wet. Her tongue subconsciously stuck out as her mouth slacked off. 

Fortunately, inside the wardrobe was dark, so no one could see her dirty appearance. 

Otherwise, they would definitely be disillusioned since the wife of the leader of their leader would show such a disgraceful expression. 

Meanwhile, afraid of being noticed, Shinobu couldn't do anything about Amane. In the end, she could only give up and continued to peek since she would be lying if she wasn't curious.

Yet, watching the joy that came from Kanae's lewd expression as Isao's cock sank into the depths of her pussy, a question emerged in their minds. 

Was it so good?

Such curiosity couldn't disappear from their minds until the next day when they returned to their room.
