Two sisters

Laying on her bed and staring at the ceiling of her room absentmindedly, Yuu reflected on herself. 

Was she such an easy girl?

Was she so desperate that she could accept him to date her with others, too?

Moreover, how could she let her most important place be ravaged by his fingers?

Yuu was at a loss, yet even so, the pleasure that her body felt was still vividly recalled by her. Unlike when she touched it herself when Mizuto touched her, it was just... indescribable. 

"Uhhh!" 

Yuu rolled around as she hugged her pillow, feeling embarrassed and also annoyed. Still, if her mother didn't suddenly interrupt them, then probably...

'I wonder how it feels...' 

Even though she hadn't seen or touched it, she had seen the silhouette of his erection, and she knew that he was huge. 

"Why am I so perverted?!" 

Suddenly, she only remembered how vulgar her thought was. Even though she knew that this shouldn't be done and she should reject him, her body kept seeking him, which made her helpless. 

"It is all his fault..." 

If Mizuto hadn't appeared in her life or hadn't done something like that to her body, then would she have been troubled like this?

Yet, Yuu also felt sad as it was too late for her to realize her feelings. 

'If I realize this feeling earlier...' 

If she had realized this feeling earlier, then all of this would have happened. 

'By then...' 

By then, he would be hers alone, and there would be no need for her to share him with anyone. 

'No.' 

Probably, this wasn't possible, especially when she knew that Mizuto was still incapable of feeling in love with anyone, yet even so, she knew that he wished to get her body. When she thought of this, her body became hot, and her thighs squeezed as she thought of his hot and hardened erection pounded violently into her innermost as she could only whimper and drown in the waves of pleasure. 

"Ugh..." 

Yuu looked at her panties, which had become wet once again, and sighed, wondering whether Mizuto was created in this world to seduce women. 

Was he an incubus?

Yuu thought so, but then her thoughts were interrupted when the door of her room was opened suddenly. 

"Yuu, I heard Mizuto just came earlier." 

"...Nee-chan, how many times have I told you to knock on the door?" 

Yuu looked at her older sister, Rei Koito, helplessly. 

"It's okay. It's okay." Rei closed the door, then asked, "So, where is Mizuto?" 

"...he had gone home." Yuu was speechless and then asked, "Why did you look for him?" 

"Why can't I? I just want to talk with him after all. I am not going to steal him from you, okay?" Rei pouted and teased her little sister. 

Yet, Yuu was in silence and wondered whether Mizuto had seduced her big sister, too. Frankly, when she thought about it, the relationship between Mizuto and Rei was quite good. Yet, the thought of them having a relationship never crossed her mind as she knew that her older sister had a boyfriend, and they had been dating since high school. If there was nothing wrong, then they would marry each other once they had settled down. 

So, would Rei abandon her boyfriend for Mizuto, who was such a bastard?

Yuu had a hard time believing, but... she didn't think the possibility was zero. 

Nevertheless, Rei didn't know what Yuu was thinking; she only approached Yuu closer with a mischievous grin like a cat. 

"Yuu..." 

"Wh-What is it?" Yuu subconsciously moved back when Rei tried to approach her. Nevertheless, the next time, she thought of locking the door so her older sister wouldn't enter her room when she was in this situation. 

'Ugh... my panties feel uncomfortable...' 

When Yuu thought about her wet panties, it made her flustered. 

"By the way, have you done that?" Rei suddenly asked. 

"...that?" 

"Geez... don't make it say it, okay?" Rei blushed, then said softly, "Have you had sex with him?" 

"....." 

Yuu was in a daze, staring at her older sister in disbelief, then got angry. "Wh-What the hell were you saying all of a sudden?!" 

"Not yet, huh?" Rei somehow sighed in relief. 

"..." 

If possible, Yuu wanted to slam her pillow on her older sister. Still, she wondered whether her family had thought of Mizuto as her boyfriend. If so, then what would they think if they knew the truth?

Yuu wasn't sure, but she was sure that Mizuto might be beaten up by her family, so she shut her lips. 

Still, Rei wasn't done with her question and asked another question. "Then, what about a kiss? Have you done it?" 

Facing this question, Yuu only looked away and didn't say anything. 

"....." 

Rei looked at Yuu in shock, then sat on her bed helplessly and said, "As expected, he is such a scoundrel, huh?" 

Yuu wanted to argue, but she couldn't since she knew that guy was so bad! 

"By the way, Yuu. It's for you." 

"What?" 

Yuu felt weird when Rei suddenly gave her a gift, and this made her curious about what kind of gift her older sister gave her, yet when she looked at the small box in her hands, she was dumbfounded. "Th-This is..." 

Condom. 

Even though Yuu had never bought it, she had seen it in convenience stores or many places, as this was an item that was commonly seen everywhere. Frankly, when she visited a convenience store, sometimes, her eyes were always drawn to this item as she knew that in the future, she would use it, yet she didn't expect that her older sister would give her this. 

"With his nature and personality, it is the only time that you two might do it together," Rei said softly. 

Yuu didn't refute it since that was the truth.

"Tell him to wear it, okay? It won't be good to do it raw." 

Yuu listened to Rei's advice and took the box silently. Still, there was something that she had to say, "Thank you, Nee-chan." Her voice was soft and almost couldn't be heard, yet it made Rei more complicated, especially when she knew her little sister was going to be devoured by that young beast. 

'Mizuto...' 

Rei thought about their meetings, and even though she knew it was wrong... she just couldn't help but draw toward him. 

Still, this young man was something that had been marked by her little sister, so she knew that she shouldn't do anything. 

Yet—

"By the way, Yuu." 

"Hmm?" 

"After you did it, tell me how it was, okay?" 

"...." Yuu. 

Nevertheless, Mizuto didn't know what the Koito sisters were talking about. Instead, he went home with a bag filled with language instruction books and Russian novels. Still, he had to say he felt relieved and great, as he was able to make Yuu agree to his relationship with others. 

As long as there was will and courage, everything was possible, Mizuto thought. 

Yet, Yuu was only the start, and there was still another girl who needed to hear his explanation.

However, unlike Yuu, Yume's situation was quite complicated as they were siblings and an ex-girlfriend, and more importantly, Mizuto had eaten everything about Yume. Every part of her body had been marked by his semen, and her personality was more extreme. 

Suddenly, he felt a sudden pain in his waist, which made him helpless. 

'In the end, it's like this, huh?' 

Mizuto thought that he needed to prepare himself to be stabbed. 

As long as he could stay alive after a single stab, then everything was possible. 

With that determination, he decided to go home, but then he heard a commotion near his neighborhood. 

"If you give up, it will be easier. Don't you know how much debt that your former husband has?" 

"It's okay. I can just sell my house. If that's not enough, I can repay our debt slowly, so please leave now." 

"Hmph! Do you think you can get away from me?! No matter what, you are going to become mine!" 

Mizuto frowned and quickly approached the source of this voice, and as expected, it was Rinko Akashigata's voice (the housewife in the neighborhood with whom he had slept). However, at this moment, she was surrounded by several men in suits who appeared as bodyguards and one middle-aged man with a big belly and sparse hair who appeared to be their leader.

This middle-aged man clearly showed his lust and greed toward Rinko, and along with his bodyguards, they surrounded Rinko.

Many people saw them, yet they only looked away, ignored them, and ran away, as they could clearly tell that this group of people was a yakuza. 

Yet, Rinko was still calm, facing all of them, unbending, wearing her usual beautiful and elegant kimono. She was like a maple tree that stood in the storm with its stunning red leaves. 

"You think the Aoi Festival can help to promote your school?" The middle-aged man smiled disdainfully and said coldly as his hand was about to reach Rinko in fascination, "You are too naive. With me here, you won't be able to—" 

"Is there something wrong?" 

Before the man finished his words, a loud voice interrupted them, causing them to frown and turn their heads before they saw a young man who came in their direction calmly.
