My Stepsister in Kyoto

"It's like this..." 

"Ah, I see! I understand!" 

Listening to Mizuto's explanation, Tsubaki quickly understood the formula of the question that she was confused with, and she was happy to be able to do so since being able to do something a happy thing and being able to do a difficult question that she has struggled naturally gave her a sense of satisfaction. At the same time, she was speechless. Watching how attentive he was at teaching her, she had to say she misunderstood him. She thought that he would attack her immediately when they entered her room, but he seriously told her that he was going to teach her. 

While Tsubaki had to admit that she enjoyed studying with him, this was different from what she imagined! 

Observing him, she wondered when Mizuto went to attack her, yet he didn't have any intentions to attack her at all, so she thought for a while and decided to make her advances.

As if unintentionally, she put her hand on his thighs and rubbed it slowly, but when she was about to say something in a meek voice, Mizuto held her hand and said, "If you do well on the exam, I will stay with you for an entire day. By then, we can have sex until you can't get up any longer. It will be something more amazing than you have ever tasted."

*Gulp!*

His voice was slow and deep, yet it contained a powerful seduction. 

Moreover, due to his "Musician" job, his voice was naturally attractive and could make anyone wet.

"Re-Really?" Tsubaki looked at Mizuto expectantly, thinking about the hot sex they would have when she got a good score on her mid-term exam. At that time, when everything that was held back was released, she could imagine how amazing their sex would be~! 

"Yeah, so do your best." Mizuto smiled softly as he patted her head. 

Feeling an expectation and happiness, Tsubaki decided to work hard to study! But then, soon, she woke up and felt complicated. Why did it feel like she was the one who was seduced?!

Yet, Tsubaki also felt like Mizuto was a father figure to her, even if they were the same age. Her father was good for nothing, and as a high school student, she had many physiological needs. 

Frankly, it was complicated, yet this also made her feel that she wanted to be with him more. 

She wanted him to look at her more, even if she knew that it would be hard. 

"Come on. If you answer all of those questions later, I will reward you." 

"Re-Really?" 

"Yeah, so go and study." 

"Um~!" 

Watching Tsubaki, who started to study hard, Mizuto felt like he was Tsubaki's father, yet this role might not be wrong, especially when Rinko, her mother, was his woman. Still, if he was a real father, then this relationship was definitely inappropriate, but then, he felt like... he was a naughty uncle. 

At the same time, the role of "Sugar Daddy" was quite unique, he thought. 

Mizuto didn't hate this role; he thought it was an amazing experience that allowed him to grow as a human being. 

Still, while they studied hard, the door of the room was knocked lightly, and Rinko opened the door quietly. She thought that they might do something naughty, but she was surprised to see that her daughter and Mizuto studied together.

No, instead of studying together, Mizuto taught her daughter. 

While feeling complicated, Rinko had to say that this wasn't bad at all. It felt at ease somehow. Yet, she couldn't deny that this was quite bizarre since instead of a young man, Mizuto was like an older man somehow. However, when she thought about how reliable he was, she didn't feel surprised. 

Still, the thought of her joining her daughter to do something naughty was also erased since they were studying hard, so how could she be so horny to interrupt them? 

Frankly, she wished for this to continue, and it would be great if Mizuto could marry Tsubaki, but was it possible? 

"Mom?" Tsubaki looked at Rinko in wonder. 

"I have brought some refreshments." Rinko then came in and brought some cold teas and snacks. 

"Thanks." Mizuto accepted Rinko's offer right away as if it wasn't his first time here and even ate the rice cracker with ease.

Still, watching this, Tsubaki felt like Mizuto hadn't come to her house for the first time. Instead, he should have come many times when she didn't know. 

On the other hand, Rinko felt a little hard, but she just smiled since it didn't matter even if their relationship was known. She wasn't naive, and she knew that her life and daughter were tied to him. They couldn't escape. No, they could escape, but if they escaped, they would lose his protection, and by then, other men would do something much worse for them. 

It might seem like she was living in a cage, but wasn't everyone like that? 

Everyone had a cage, something that tied them if they wanted to stay alive, especially those who received something. 

Rinko had received many things from Mizuto, whether peace of mind or comfort in her heart and body, so it was natural for her to be willing to give her everything. 

Yet, Mizuto had to say, Rinko, who was in plain clothes, was so charming. She might only be wearing jeans and sweaters. There shouldn't be anything lewd about her, but the silhouette of her body on those clothes made him unable to look away. 

From her shapely bottoms, long slender legs, and willowy waist, then a gentle yet adequate swell on her chest. 

All of those factors made the appearance of this woman become so charming, especially when she was also a mother. 

While Mizuto tried not to gaze, Rinko seemed to notice his gaze, and it made her smile, but then, an accident happened. 

"Ah!" 

The tea on the table fell, causing all the liquid to fall on Mizuto's pants. 

"Ah, I am sorry, Mizuto-kun! I will wipe it right away!" 

Rinko quickly took some clothes and then wiped Mizuto's pants, which were in his nether region. 

"Wa-Wait!" 

Naturally, Mizuto couldn't stay calm since he had a bad time holding on, and if this woman touched him, then the natural reaction would be obvious. Yet, when he looked into Rinko's eyes, he realized that this woman did this deliberately. Watching her naughty smile, he was speechless. 

He tried seriously to teach her daughter, yet this was how Rinko repaid him? 

What a despicable mother! 

"Mom, what are you doing?!" 

Tsubaki, who had been focused on her study, was naturally disturbed, especially when she saw her mother rubbing Mizuto's nether region, and this perverted act naturally caused his erection. 

Mizuto was helpless, but Tsubaki and Rinko saw the prominent bulge on his pants, which was impossible to hide. 

The two gulped, but Rinko took the lead first. "Come with me, Mizuto-kun. I will wash and take care of your pants." 

What could he do? 

As a good boy, Mizuto decided to obediently follow Rinko while trying to cover his nether region. 

"Okay..." 

Yet, watching how they left, Tsubaki narrowed her eyes, and as expected, the relationship between Mizuto and her mother was unusual.
