Sayuri: "I will educate you~!"

"Sayuri-san..." 

"......" 

At that moment, everything stood still for Sayuri, especially when she looked at his embarrassed and awkward expression, especially when Masa showed a reaction that he shouldn't have toward her, the mother of his girlfriend. 

Usually, Masa could control it well, using his strong will to hold on so he wouldn't show a reaction despite being so close to Sayuri. While she was a charming woman, he knew well that her status was someone that he shouldn't be with, and a dirty thought shouldn't have even appeared in his mind, yet how could he not when she was such a beautiful woman? 

Sayuri's appearance was similar to Eriri's; their only difference was their hair color, but unlike Eriri, who often appeared childish, Sayuri had this mature-like charm that couldn't be owned by a woman of his age. 

However, as he had given up, he didn't have to hide it anymore, and he had to show her that she shouldn't be so close to him like this. 

Still—

"I am sorry." 

Even so, Masa had to apologise as he knew well how incredulous and presumptuous his action was, but—

"I won't forgive you." 

"Ha?" 

The gentle and perverted image that Sayuri had shown was no longer there, instead she appeared cold and stern, like her expression when she faced those shitty people for her business. 

"..." 

Did he miscalculate? 

When he thought so, Sayuri moved even closer as she looked at him with an even grim expression. "How could you react this way with the mother of your girlfriend? If you are like this, how can I entrust you with Eriri!" 

"...I am sorry." 

What could he say? 

Masa could only apologize, but Sayuri said, "No, I can't let you go like this." 

"Then?" 

"I will educate you."

"...educate?" 

Watching his confusion, Sayuri stroked the hardness that pressed against his belly as she looked at him with a cold expression. "This naughty boy here has to be educated, so when the school finishes, don't go home and stay at my home first." 

Yet, despite saying harsh words, her expression was filled with excitement and extremely lewd, but fortunately, she was a woman with experience; she moved closer to him, pulling his tie as she whispered into his ear, enduring the feeling of wishing to gobble him up now. 

When she thought of that all-mighty and superior man like him succumbing under her as he screamed in pleasure, Sayuri felt like... something inside her might explode that she didn't care about anything else. 

However—

"Mom! What are you doing?! Stay away!" 

The familiar voice was heard by Masa and Sayuri. 

Sighing helplessly, Sayuri whispered, "Calm down. Don't let my daughter know." 

Why did Sayuri have to use the word "my daughter" instead of "her"?

Yet, the shock that came from having to know the gentle and kind mother-in-law, who had always supported him, showed such sadness and strictness, which made him conflicted. 

Did Sayuri read the father-in-law type of doujinshi last night? 

Finding out his daughter-in-law had a dirty secret, the father-in-law couldn't stop his dirty claws and touched the woman that he shouldn't touch, and facing his advances, the daughter-in-law could do nothing except for succumbing. 

This was probably how he was to be, yet he had to say this woman was amazing since as Sayuri faced her daughter, her expression returned to normal, but her hand lightly flicked his hardness, rubbing it lightly as if trying to appraise it, then glanced at him with the corner of her eyes. 

"Calm that down, okay?" 

"..." 

Don't ask for the impossible! 

Still, Masa quickly backed away, thinking that he shouldn't visit Eriri's home for a moment. 

Then again, if he went home—

Sighing, he wondered why all the women around him were all perverts. 

"Geez, it's early in the morning. You shouldn't be so noisy, Eriri." 

"What are you doing?! He is your son-in-law! I am going to marry him, so don't touch him!" 

"What are you afraid of? I am your mother, so how can I steal him from you? Instead, isn't it good that I am helping you?" 

"You...! You...! You...!" 

It was fortunate that their house was a huge mansion, so their loud conversations wouldn't be heard, which might cause a scandal. 

"What are you thinking of, you pervert!" 

Sayuri flicked her daughter's forehead and side, "Anyway, hurry up and go to school. You don't want to be late, right? Even if you are alright being late, it isn't good for the top and good students like Masa to be late, right?" As she said so, she glanced at Masa with a gentle smile. "Right, Masa~?" 

"....." 

What was wrong with those women? 

"Ah, um." 

"See~?" 

Eriri felt like they were hiding something from her, but somehow, instead of grumbling and getting angry, her face became crimson, her breathing became harder, and her expression was so distorted that her cute face became lewd. 

"....." Masa. 

"...well, I will go now with Masa." 

As Eriri said so, she quickly linked her arm against his, showing her sovereignty as if telling her mother that Masa had always been his! 

Still, Sayuri was calm and even showed her composed smile as if she had done nothing previously. "Then, take care~! Have a good day~! Also, hurry up and go back, okay~?" 

"...um." 

It was like throwing her small fist into cotton. Eriri felt her revenge did nothing to Sayuri, so she could only grumble as she left with Masa, but what she didn't know when they were about to walk away, Masa felt his buttocks were grabbed, which made his body all tense, but he didn't turn and just walked away as if nothing had happened since he knew well who had molested him. 

Still watching them leave, Sayuri licked her small, pink lips and couldn't wait for him to return~! 

"Oh, right~! Let's shave it first~!" 

It had been a while, and Sayuri had to admit that she was so excited that she walked in a skip, ignoring the luster of liquid that stained her smooth and white legs. 

"So, we are going to walk?" 

"You don't want to?" 

"No, it's fine, but why?" 

"I just want to walk for a while." 

"Well, if you say so." 

"It's also good for your workout, right?" 

"If it's a workout, we can do it at my place, right?" 

Watching Eriri's eager expression, Masa was speechless, thinking that whether a mother or a daughter, they were all the same. At the same time, he wondered why he thought so much. 

Why couldn't he be like those Masa from One Piece, DxD, or Mahouka? 

After all, none of them hesitated and jumped right away toward the opportunity before them. 

"By the way, are you not curious about Nozomi-nee's underground fighting arena?" 

"Oh! Finally! Tell me! Tell me!" 

As he said so, Eriri was distracted as she was curious about the underground fighting arena where Nozomi, Masa's older sister, had made her friends. Frankly, she might appear silly, but she wasn't naive as she knew well the dirtiness of the upper society, and at the same time, probably because she was an otaku, so she could accept all the strangeness that appeared within the world. 

In other words, Eriri's tolerance was high! 

Still, Eriri enjoyed this well, the fact that they walked next to each other, holding hands toward the school together. Her dirty heart somehow slowly became smaller, yet it didn't disappear. It was rooted within the deepest space within her mind, lurking, and sparked when a slight ignition happened, like this, when they arrived at the school, and the plain junior, whom they met yesterday, came in their direction. 

"Masa-senpai! Eriri-senpai!" 

"Oh, Ririsa-kun." Eriri nodded, greeting Ririsa with a smile. 

"Good morning, Ririsa." Masa also greeted me. 

"Good morning!" Ririsa appeared as usual, naive and a bit silly, but the words that came from her lips caused a distorted feeling in Eriri's heart to spark. 

"Eriri-senpai, can I have Masa-senpai to take my photo today?" 

"..."
