"Come on! Go and take a bath! I will prepare your clothes."
"Okay."
As they entered their house, which was located in a residential area that was quiet yet secure, as it was located in a place where most of the wealthy people lived.
Or rather, this area was created based on his whim to make a real estate business, buying cheap land, and turning it into high-class property that would be sold hundreds of times at the original value.
Many people lived there, including Makarov, the government, and even the nobles.
As for the security, it was top-notch as it was protected by the Fairy Tail, and this was the reason why Makarov loved Sato so much, as he had many methods to make money.
Yes, Sato might be average, but even so, his mind was agile, and he tried to compensate for his weakness by doing something else. Fortunately, at this moment, he wasn't so powerless, and with all of the information that was collected by Sato DxD, he could develop many things, which was impossible in the past, as he was once again just average.
Still, even so, he knew a lot of people, and he knew how to utilize people as his mind was quite agile and flexible, different from the people of the current world, who were still trapped in their incoherent thoughts and the common sense of this world.
Yet, as he removed his clothes and prepared to take a bath, he felt relieved by Sato DxD's intention to grow stronger.
Frankly, he wasn't much better, thinking of leaving most of the things to the protagonists and just living like others, calmly, peacefully.
Still, if he had the power to protect himself, at least, it would be better, right?
After all, while he hadn't been targeted yet, as he was part of the Fairy Tail, when this guild was targeted, he would fight alongside everyone.
'But, what's the problem with the world of Fairy Tail?'
The main conflict that he could think of was definitely the relationship between the kingdoms on the continent, the evil magicians, and the cultists. There might be more, but the main problems were more or less those he mentioned before.
'But, on the cosmic level, huh?'
The main enemy of the world of DxD was definitely the alien, or the creatures from another universe that invaded the world of DxD.
Meanwhile, on his side—
"It isn't much different?"
After all, many of the problems of the world of Fairy Tail reached the scale of the planet, or even beyond.
"...isn't it better not to do anything?"
Similar to before, while he had learned the Giant Magic and the Archiver Magic, he didn't learn the rest, as he knew that the result was just so-so, and even if he learned it, would anything change?
The scale of the problem was already so huge that he felt that it was impossible even if he and Sato DxD combined themselves together.
Instead of working hard when the result was doom, wasn't it better to just lie down and leave everything to the protagonist?
Somehow, at that moment, he felt like he understood the feelings of those young people who followed the path of the "lie down movement," where one decided not to work hard, but just to work enough, so they wouldn't die early.
Yet, even so, even if they knew that the result wouldn't be good, and it was better to do the same thing as before, it just felt wrong to just give up without doing anything.
Did they seek the consolation prize, so that when they failed, they could say, "At least, I did my best."
Was it like that?
Also, didn't he pay the price for his foolishness, thinking that he could change anything before, yet in the end, he lost his ability to walk?
However, another chance had emerged before them, so why should he hesitate, then?
Just as his spirit rose, another part of him also rose when the door of the bathroom was opened by Mirajane.
"What are you doing? You haven't even washed up."
As she saw his figure, who just sat down seemingly in a deep thought, Mirajane sighed. "Come on. I will wash you up."
"....." Sato.
"What are you shy about, huh?"
As she saw his reaction, she couldn't help but giggle, yet even so, it was all probably an attempt to hide away her embarrassment that came from seeing his naked body.
His immensity was exposed, and nothing was hidden.
As a man, Mirajane could see how well-endowed her boyfriend was.
Yet, Sato also couldn't look away from her, since even if she wasn't naked, her current appearance was just so alluring.
Wearing simple shorts that showed off her toned, healthy, soft-looking thighs, and a white tank top that showed the straps of her bra that tightly wrapped around her round, smooth shoulders, Mirajane simply tied her long silver hair in a low ponytail with a pink-colored scrunchie.
Everything about her just hit straight to all the elements that made his lower body react, especially that scrunchie part, which she used to tie her hair in a ponytail, as it gave her a lewdness that was hard to describe.
Probably, it was just his opinion, but instead of the vulgar nakedness where women showed their everything without any shame, he loved to see the charms in their casual moment, during their most defenseless moment, as in that moment, despite being plain, it was erotic.
Only—
"W-Wait!"
Before he was even able to give a proper response, his body was already wet as Mirajane poured water on him before she put soap and started to wash his body without even waiting for his permission.
"The stink will stick if you don't wash it soon."
What kind of a stink?
While he was helpless, he couldn't even complain as her body stuck against his back, making him able to feel her soft body despite being hindered by her clothes, and her naughty hands started to grab and wash his hardened area thoroughly.
"Hmm... did you use the Giant magic?"
"No, it became better as I walked."
"That's a nice bonus~!"
"....."
Sato was speechless, yet Mirajane put her lips against his neck, sucking him, as she whispered to him seductively without stopping her hands, breaking away all of his reason as she whispered, "Sato, I have been a good girl, waiting for you patiently, so can we now?"
In that moment, something snapped within him, and he truly made her his.
As the two became one, this was something that had become one, and the feeling that came from their union was just so delightful that they became careless as they didn't realize a naughty figure peeked at them, squatting down, as she opened her legs carelessly, touching herself lewdly as her eyes stared at their direction obsessively, wishing to be in the place of her older sister.
"Onii-chan..."
Her voice was quiet, yet it contained an unstoppable desire that was impossible to stop.
