Ultimate Being from the Tokonosu City

Chapter 99: Human Greatest Invention

Coming to Yokohama, Isao quickly changed gears and became a respectable leader who was trusted and worshipped by everyone. His knowledge, decisiveness, and charisma made everyone follow him without hesitation. In just a few days, he was able to develop something that had stuck for many, creating a new invention that changed human life. 

Still, when Isao returned to the hotel, he was welcomed by Kie, who waited for him obediently and helped him manage the stress of working hard. 

If Isao had to say, it was like how a factory had to cool down after it worked so long, creating so much of a heat. 

Kie was that cooling system prepared by his women to take care of all the heat inside his body. 

"Geez, nothing will come out even if you suck them." 

Kie looked at Isao helplessly when he sucked her hardened nipple, but soon, she bit her lip since it felt great when he twirled her nipple with his tongue. 

Yet, during these days they stayed, she had been helping him with various things, from using her hands, mouth, thighs, buttocks, breasts, and even feet. Except for her most important place, all of her body had been bathed by his semen.

Still, she didn't mind this, and to be honest, it was her first time to feel like this, and sometimes, it would be great if these days could continue. There was no need to think about anything else except him and her enjoying their time together. 

While he worked, she would support him, and when he went home, they would have fun together~!

At this moment, if her children saw what had happened to her, there was no doubt that they might not be able to believe that such a virtuous mother could become like this, yet before she was a mother, she was also a woman, and she also had her own need. 

However, compared to her needs, the needs of her children came first. 

Still, by his side, all of her children's needs had been taken care of, so she could focus on Isao and help him with various things.

While she might not realize it, she might give her excess love to Isao, too, especially when he was young. He also told her that he didn't have parents. Knowing he was alone and kept working hard while wishing for a family, her maternal instinct awoke, and she gave him all of her love. 

Like after he went home from work, she had been doting on him, letting him play with her body with various plays that she had never thought of. 

Yes, it was perverted, yet it was kind of fun~! 

Somehow, Kie understood why Kanae, Hinatsuru, Makio, and Suma stuck to Isao all the time. 

"By the way, how is the tire in your factory?" 

After having fun, while they ate together, Kie often talked about what Isao did since his story had always been interesting. Unlike in modern times, when one could see romantic drama all the time on television, there was hardly anything interesting about everyday matters, so sex had always been part of the fun. Naturally, the conversation was also part of the fun, and his story about business was interesting, especially when her world had always been in the small village. 

As for her daughter, while Kie wanted to do something about Nezuko's situation, it was impossible to do it in a hurry and to solve this problem, she might need a few years. 

Waiting for her son was fine, yet she didn't want to be useless and wished to do something, especially to be Isao's help. Yes, she might not have much of an education, but she could learn. 

"It might take a while for it to be ready, but I have just finished a byproduct from my rubber factory." 

"By-product? What kind?" Kie asked curiously. 

"The greatest human invention." Isao took out several small items from his pocket. "A condom." 

"Condom?" Kie felt strange and looked at many small items on the table curiously. "What is it used for?" This item was so small and a little slimy. At the same time, the shape was kind of strange. 

"You can use it for many things, such as storing a few liters of water during a critical situation or helping one to prevent a pregnancy and STD." 

"Wh-What?" 

Storing water aside, Kie blushed when she realized what kind of an item a condom was. Yet, this also made her curious, and she realized why it had a strange shape. "I see... you use it like this..." 

To teach Kie so she could understand the importance of a condom, Isao taught her how to use it. Moreover, as the boss of his rubber manufacturing factory, naturally, he had to test whether his product was effective or defective. 

Kie, who was his employee, was more than happy to help her boss, who wished to help the entire humanity with his creation. 

Still, there was no hesitation between them, the relationship between them was so close that she allowed him to suck her nipple, and the only thing that stopped them was that Isao was afraid to make her pregnant, but with this creation of his, he could prevent that. 

Staring at Kie's ripened body, who lay on the futon as she opened her plump, white thighs, showing her mature pussy that was so wet, seemingly ready to welcome him anytime. She knew that the time of this would come sooner or later, and she also anticipated it. 

"You don't need to hold back, Isao-sama. You can use mine as you wish." 

However, Isao thought for a while and decided to change their position. As a man, he should have taken the initiative, but as Kie was an elder, he felt that he needed to show some respect toward this widow, so he decided to lie on the futon and let her take the initiative. 

While Kie was embarrassed, she straddled his waist with her lustful body, moving her naughty hips, having intercrural sex. She was ashamed, but as she was older and more experienced, she felt that it was understandable, yet she had to say, this was so embarrassing! 

However, as she moved her hips faster, the pleasure she felt became even more intense, and her pussy became even wetter. Still, when she was soaked, she stopped and knew that it was time. Lifting her big buttocks slightly, she held his large cock, and aimed its head at her entrance before slowly letting it enter her inside. 

"Oh~!" 

Her pussy, which had been tightly closed, slowly widened by his cock. 

By then, nothing could stop them anymore, and the devoted widow surely fell on the arm of this naughty beast. 

Yet, Isao was a good person, so he was going to take care of this poor widow. 

"Ahnn~! Oh~! Harder~!" 

As she cried, Isao held her, comforting her and telling her that everything would be okay. 

At the same time, this was also the first modern condom that had been created, and its effectiveness had been greatly studied by Isao. Still, quality control was his invention that needed to be tested even further, and for the entire night, Kie had accompanied him on the journey to help humanity. 

Yet, as she was pounded by Isao from behind like a bitch, Kie knew that Isao was a naughty boy~!
