Lullaby

Appreciation. 

Yes, at this moment, his heart was filled with appreciation and gratitude, especially toward the system, his decision to acquire a hotel, and also toward life. 

Yet, how could he not be?

After they had digested their food, they decided to visit the spa, where they could enjoy the thermal pool. As Mizuto had reminded them to get their swimsuits, they did, and they changed into such attire before they entered the pool.

As a man, except for enjoying this situation, what could he do?

Still, from their personality, it was easy to tell their choices of swimsuits. 

Showing off her petite and youthful figure, Akatsuki wore a yellow bikini. Yes, compared to the two, her growth might not be comparable, yet she had her own charm, and she knew how to utilize it. 

Mizuto glanced at her and couldn't help but glance at her slender, white legs, which were slightly rosy and moist due to the warm temperature and humidity of the thermal pool. Her chest was small and just appeared to be bulging, yet even with such a chest, it was impossible to hide her womanly charm, which he had picked up and nurtured. 

Watching Akatsuki, who smiled at him mischievously, Mizuto felt his lips dry, so he put his attention to his stepsister. If Akatsuki was like a sunflower, blooming brightly, facing the sun, then Yume was like a jasmine, quiet yet graceful. 

Yume wore a white bikini and tied her hair into a ponytail, which she let rest on her bountiful chest. 

Mizuto might have seen her naked figure so many times, yet when they were wrapped in such provocative clothes, it made him realize that he knew nothing of the charm of a woman. Being naked might be beautiful, but when lightly dressed, it tickled man's imagination, wondering what was hidden inside.

A man was an adventurer being, after all, so this couldn't be helped, right?

Still, when he thought about her lustful figure, which he pounded from behind, dominating, yet kept trying to comfort him, and even enjoyed his forceful side, he realized that purity and sensuality were two sides of the same coin. 

Yume, who was known as a good girl who followed every rule of the school, like how a good student is, was a pervert who loved to suck his penis. 

Nevertheless, he was the only one who knew such a side of her, and as if noticing his gaze, she looked at him shyly as she lightly caressed her ponytail. 

Yet, he had to say that compared to Reina, Akatsuki and Yume lacked an impact. 

While Reina was often dressed femininely, her bikini was strangely bold with a black color. Still, comparing her to bikinis, her breasts appeared more domineering. 

He might have said that her mouth might be the most charming part of her, yet it seemed he was wrong as he knew that her breasts were definitely the most charming part. They were bulging and appeared full under that tight black bikini as if they might spill out anytime. 

If he compared her to a flower, she was like a delphinium. This might be strange, but her appearance was so impactful that he could only compare her to this flower. It was like a rainbow after the rain, an aurora on the north, or sunset on the most breathtaking scenery; her breasts had such an impact on him. 

Mizuto had to be thankful to Reina's parents, who gave her permission to come with him on this trip. 

Nevertheless, like him, the three girls were also attracted to him, especially when he wore nothing but black shorts, showing his muscular and manly body, which was wet from the water. It felt like... they might have a nosebleed if they kept watching him. 

"You three look great." 

"You are the same, Mizuto-kun." 

"I am just wearing a short, though." 

"Even so, it's dangerous. Try not to appear in a public pool or anything similar. I am afraid that you might be raped by women," Akatsuki said solemnly, gaining the nod of the two girls. 

"....." Mizuto.

Nevertheless, the four of them soon entered the thermal pool since even if the weather was perfect, it was rather windy on the bay, making their bodies a little cold, so they wanted to get the warmth by entering the pool. Still, due to this, their bodies became wet. 

As their bodies became wet, Mizuto thought that there was a certain charm on the woman's wet body. Their lustrous skin, tightly wrapped wet clothes, and some of their hair stuck onto their cheeks.

Still, the pain in his waist quickly woke him to reality, and he saw Yume, who was staring at him with a smile. 

"Are they beautiful?" 

"You are the most beautiful, Yume." 

"Hmm..." 

Yet, with those words and his gentle hug on her small waist, Yume didn't reject him and enjoyed his hug, but she realized that this guy was greedier than she had thought as his naughty hands started to slip into her buttocks, gently kneading the cheek, feeling the smoothness and bounciness of her round buttocks. 

"He-Hey..." 

Yume panicked as she knew that Akatsuki and Reina were there. 

"You don't need to worry. They are not looking in our direction." 

Unlike Yume, who faced in his direction, Mizuto was facing Akatsuki and Reina, and he could see that they were talking to each other. While he wondered what they were talking about, he knew that this wasn't the time for this. 

"Be patient, okay? Wait till tonight..." 

While this situation strangely made her body excited, Yume felt that this was too dangerous. Still, he didn't let her go, which made her even more panicked.

"If you call me Onii-chan, then I will let you go." 

Hearing his words, she was startled, looking at him with shock. Still, she pursed her lips, biting her lower lip, then said softly, "O-Onii-chan... wait till tonight, okay~?" 

Hearing her words, he let her go obediently, causing her to glare at him, but watching her pouting cheek, he couldn't help but kiss her cheek, which made her react even more strongly. 

Yet, their interaction was watched by Akatsuki and Reina, who felt so helpless at that moment. Still, this made Reina, who hesitated about Akatsuki's proposal, nod. 

While Yume wished to enjoy more time with Mizuto, it was impossible to ignore Akatsuki and Reina, so after they stayed at the thermal spa for a while, they decided to take a spa course for a while, leaving him alone. 

"Is it really okay?" 

"It's okay. Just enjoy it. There is no need to hold back." 

Anyway, all the things in this place were his, so there was no need to hesitate. 

Nevertheless, due to this, Mizuto knew that he was thinking of the need to acquire more hotel brands, especially luxurious ones. Moreover, he was also thinking of renovating some of his deluxe hotels into luxury. While thinking so, he decided to have a quiet time on the private onsen nearby. 

There might be some other guests other than them, but due to his special identity, no one bothered them, and no one troubled the hotel either as everyone became obedient with these skills from the "Hotelier" job. 

Yet, it didn't mean no one would bother him. 

The sudden knock on the door of the private office woke him up, and he saw Akatsuki looking at him with a mischievous smile. "Are you not taking a spa with the others?" 

"I want to stay with you more, though." 

Entering the indoor onsen area, she washed her body before she sat next to him, leaning by his side and then staring at his lower body, which was practically naked. 

"Why are you naked?" 

"Well, I am alone, so it can't be helped, right?" 

"....." 

Sometimes, Akatsuki wondered whether Mizuto had an exhibitionist hobby.

Still, as she kept staring at it, considering how cute it was when it was sleeping, she realized that she had been bothering it, and soon it woke up, showing how angry it was. 

"Akatsuki..." 

"You don't need to worry. I will take responsibility." 

Her voice was so gentle, and her hand stroked it gently with care before she opened her lips, ready to sing a lullaby for it.
