My Stepsister in Kyoto

Yumi Mishima wondered what to do. 

It was just a prank, especially when she knew that her twin sister Ootake Nami was the homeroom teacher of the famous high school sax player, Mizuto Irido. 

When she knew that, she thought of disguising herself as Nami, thinking that she should pretend to be his teacher, wondering how it felt to become the teacher of such a famous heartbeat in this country. 

As for why she had decided to do this, it was because she felt that her life had changed after she had given birth to her daughter. After she was pregnant, her husband no longer saw her as a woman, and instead of a married couple, they were like roommates. 

This change, while she had gotten used to it, she couldn't help but feel envious of her sister, who appeared radiant all the time. 

Was this the effect of a divorce? 

In the beginning, Ootake Nami was all dry, but somehow she had changed. 

While she wasn't sure, Yumi thought that Mizuto might be related to one after another. Still, before he became famous, she didn't know him, but as he became famous, she tried to pretend to be his homeroom teacher by asking Nami. 

Even though Nami was helpless at first, she agreed to her sister's request, but inwardly, she smiled, thinking that something fun was about to begin. 

So, their plan started. 

While Nami went to Yumi's apartment and pretended to be her sister, Yumi also went to Nami's house, pretended to be Nami, ready to teach Mizuto, giving him a prank, and talking to know what kind of a young man he was. 

Yet, unexpectedly, what Yumi didn't expect, what would welcome her, was something that she would never forget in her life. Her body hadn't been touched by her husband for a year and was held by this young man vigorously, and she could only succumb to his desire, enjoying the guilty pleasure that she had never thought. 

Yumi didn't expect Mizuto to be so aggressive, and at the same time, she realized why her sister was so radiant and appeared so beautiful, even though no man had touched her.

However, Yumi found the reason, and that was all of Mizuto. 

While she knew that it was wrong, it was already too late; her body was stained by him, and her lascivious housewife's body was vicariously eaten by him. Nothing was left behind, and he devoured her so thoroughly that she couldn't remember the face of her husband anymore. 

However, when she recovered, she realized what was happening, but as she was pretending to be Nami, she could only follow it through as if she were his homeroom teacher. 

Yet, at the same time, she wondered whether Nami felt this feeling every moment when Mizuto held her. 

Still, instead of feeling sad that she had betrayed her family and let a young man twice her age hold her body, she felt jealous of Nami, who could be held by him every day. 

Thinking of his large cock, rugged body, and beast-like expression on his handsome face... just gave her a shiver and made her pussy wet. 

Still, even though she wished the time would continue, she had to return home as she wasn't Nami but Yumi, the wife of someone. 

"Did something happen?" Nami asked with a smile. 

"No-Nothing is happening!" Yumi denied it, as it was impossible for her to tell what was happening between her and Mizuto. At the same time, before Nami returned, she had cleaned up everything, so nothing should be found out, right?

"So how is it? Is it fun to become his teacher?" Nami didn't urge her sister and just asked curiously. 

"Well..." Yumi fell into a deep silence, reminiscing the feeling of being pounded by him violently like an animal, causing her to blush, but before she said something, Nami moved closer and then whispered, "Have you slept with him?" 

"Wh-What?" 

"You don't have to hide it from me. I am your sister, after all." 

Still, how could Yumi admit it directly? 

However, Nami came closer and then whispered, "If you want, you can try to become me again." 

"H-Huh?" 

"There is no need to think too much, okay? I am sure that Mizuto wishes to be taught by his teacher." 

Instead of her teaching him, Yumi felt like Mizuto was the one who taught her, teaching the pleasure that she had never known. Still, she definitely couldn't say that, but somehow, she agreed with her sister, who told her to become his teacher once again. 

After all, there were many things that she had to teach him, and they hadn't finished their last lesson, so she knew that she had to teach him. 

Still, it was impossible to do it immediately, and Yumi had to wait for a while, but when the day came, she couldn't hold any longer. Her body that had tasted the forbidden pleasure was scorching, unable to hold the intense lust on her ripened body. 

So, when the day came, she came to her sister's room, but then, as she entered, she heard a loud lewd noise. While she was startled, she quickly closed the door so no one could hear the noise inside. 

However, she was also curious, and as expected, when she came to the living room, she saw her sister, Nami, riding on Mizuto's waist lewdly, and her large breasts shook. This scene was so lewd, and she couldn't take her eyes away. 

"Come here." 

Nami noticed Yumi and quickly beckoned her to come closer. 

"Huh?" 

However, Mizuto was stunned. No, he pretended to be surprised since there were two Nami before him. 

"She is my sister, Yumi. The one you slept with last time," Nami brutally honestly told him that the one he slept with was her sister, someone else's wife. 

"..." Mizuto. 

"Anyway, come on. Please help me. This guy is too fierce." Nami lifted her body, causing his large cock to slip from her wet pussy. 

*Gulp!*

Watching the glistening cock that was covered by Nami's love juice, Yumi couldn't look away, and her body became hotter and hotter, yet being pulled, she couldn't stop and watched Mizuto's cock that was before him. 

"Come on. Let's do it together, Yumi." 

Nami held Mizuto's cock, stroking it easily due to how slippery his cock was, which was covered by her love juice. 

Hesitating, in the end, Yumi opened her fleshy lips and sucked his cock lewdly, making a loud slurping sound as she fell into a trace, getting the thing that she had been waiting for. 

Nami also didn't lose and started to lick his balls. 

Watching the two mature sisters, who gave him a double blowjob, Mizuto lamented, wondering why all the women fell for a bastard like him, but as they had fallen, then let them fall deeper, enjoying this forbidden pleasure.
