My Stepsister in Kyoto

November 3rd. 

It was the day of his birthday, but this wasn't only his birthday; it was also Yume's birthday. 

Was it the work of fate, or were they fated to begin with? 

Nevertheless, it was amazing that they had the same birthday. Naturally, they decided to celebrate it together, going out together one day before their birthday and staying in the house together. 

Still, for their celebration, they decided to have a Christmas theme. While there was a month or more before Christmas, they decided to celebrate it early by wearing a Christmas-themed costume. 

While Mizuto dressed like a deer, Yume dressed like Santa Claus. 

Yet, even if she dressed like Santa Claus, her appearance was so lewd. She showed off her belly; her ample breasts almost slipped out due to her skimpy clothes, and for the first time in a while, she didn't wear stockings, showing her plump, white thighs. 

"You are so perverted!" 

Yume covered her legs, feeling embarrassed as she didn't like to wear something that showed her thighs. 

"...why are you getting embarrassed now?" 

Still watching her embarrassed expression, Mizuto couldn't control himself and pulled her into his arms. Rubbing his face against her neck, he kissed her neck softly, causing her body to react naturally as if a switch on her body was turned on. 

"He-Hey! I-I am Santa! As a deer, you should be at the bottom!" 

Still, as it was her birthday, she wanted it to be special and wanted to be on top, too, especially when she was Santa and he was the deer. 

"....." Mizuto. 

Watching his twitching lips, Yume laughed and rode on him well, rubbing her soft buttocks against his penis that stood tall, looking at him lewdly. "Do your best as a deer tonight, okay~!" 

As a deer, it was his duty to be ridden by Santa, but he had to say, as a proud deer, it was impossible for him to agree to this amateur Santa. 

If she wanted to ride on him, she should show her qualifications and skills in riding on him! 

Watching his proud expression, Yume pouted and said, "I am your big sister! Aren't you going to listen to your big sister?" 

"I am your little brother, so you should spoil me, right? 

"...." 

Yume rolled her eyes when she heard his shameless words. 

Spoil him?

Didn't she spoil him enough? 

Not only did she let him ride on her most of the time, letting her be humiliated as his older sister, but at the same time, she also let him have a lot of women by his side! 

If she didn't spoil him, then what was it? 

Watching her, whose eyes started to moisten, Mizuto was helpless and kissed her lips softly. 

"Hmn~!" 

Feeling this kiss, she quickly got better and clung to him tightly, letting him feel her smooth white thighs with his wide palms. 

A kiss was an incredible thing, and it also reminded them of many things, from how they started till now. When they were together, they broke up and then became one once again. Everything started with a kiss. Even though they had done it so many times, they couldn't get enough of it and kissed each other so much. 

Sticking out their tongues, clinging to each other, and sucking each other salivas. 

Their kiss was so perverted that everyone would be stunned when they saw the two most popular and smartest students would be so perverted. 

Yet, for the two, this was their daily, and as long as each other was present, they wouldn't miss out on doing this kind of thing. 

Still, as they kissed, it was fortunate that their parents were sleeping, and he had installed a soundproof wall so no one should hear how lewd their kiss would be. 

Nevertheless, unlike their previous kiss, this time, it was different as Yume gained the upper hand, and she pushed him into the bed, tightly hugging him, and never let him go as if she wanted to become one with him. 

They only kissed and took a deep breath for a moment before they continued, and they kept doing this until it was midnight, which turned the day into the next day, and they arrived at their birthday. 

"Happy birthday." 2x

The two smiled before Yume hugged him tightly, rubbing her cheek against his. 

"Should the elder sister be this spoiled?" Mizuto asked helplessly. 

"It's fine~! I am also a little sister too~!" 

Mizuto wanted to argue, but in the end, he gave up since Yume often played the role of an older sister and a little sister at the same time. When she wanted to be on top, she would be the older sister, but when she wanted to be at the bottom, she would be the little sister. 

Unlike before, she had become flexible with her role, and she didn't mind being humiliated by him. 

"Do you have a wish?" 

"Hmm... I want you to tone down the number of your women this year." 

"I will try." 

"No, you should do your best! Or rather, you have me! You shouldn't be tempted by others!" 

"Can you handle me alone?" 

"...." 

Yume let out a helpless sigh, but she also knew her limitation, so she didn't blame him much, or rather, she had accepted everything. After all, no matter what, she would be the main wife, right? 

"Anyway, you have to tone down! Don't seduce more innocent women!" 

"You are right. I will tone it down a bit." 

"Hmm... it's strange that you are quite obedient." 

Yume looked at Mizuto strangely. 

"What do you mean? I have always been a good boy!" 

"..." 

Yume's lips twitched since, no matter what, this guy was far from the description of a good boy!

"But I really plan not to seduce anymore." 

"Re-Really?" 

"Um." 

Watching his sincere expression, Yume decided to believe him, but somehow, would the other women let him go? After all, she knew that Mizuto was the best of the best, so it was normal for him to be seduced by many. Still, it didn't matter since, with the power of a little sister and an older sister, she was going to protect him no matter what! 

Nevertheless, as it was their birthday, naturally, they wanted to celebrate it together, and of course, they were going to celebrate it in their own way~!

However, when they were about to celebrate their birthday, their smartphone vibrated, and they saw many texts that congratulated them on their birthday. Still, they quickly put their smartphones away as they wanted to do it right away. Only one of those texts told them to look at the outside. 

"Hmm? What's wrong?" Yume was ready to go all out, but she saw Mizuto's expression, which was weird. 

"Everyone told me to open the door." 

"...what do they want?" Yume felt weird. 

"Let me check for a while." 

"Wait! I will follow you!" 

"Change your clothes first. I can't have a lewd Santa go outside, right?" 

"..." 

Yume looked at her clothes, then nodded. "You are right. I might destroy their innocent dream." 

"...well, there are no children waking up at this time." 

Still, as they changed their clothes, they quickly checked the entrance of their house quietly as their parents were sleeping, but when they looked at the peephole, they were dumbfounded and quickly opened the door since outside, there were all of his women. 

"Happy birthday~!" 

"...." 2x

"Let's go inside. Let's celebrate it together!" 

All of them were raring to go and wanted to do it at his house together. 

"...." Mizuto. 

Yume blinked her eyes, then asked, "Can you handle all of us?" She didn't mind, but then again, it was Mizuto strong enough to face all of them?

"Why not?" 

That was his challenge. 

Something that he had to pass through as a great man of the modern time. 

Someone might say that this was impossible, but for his future happiness, he had to win provocation. 

So, with all of that, all of them entered his room quietly and then locked the door before starting a battle that would shake heaven and earth.

Still, this was the best birthday present he received after becoming Mizuto, but then again, this definitely wouldn't be the last one, as he was sure many wonderful futures were going to wait for all of them.

The last!
