Tokyo Tutor: Starting with My Ex-Girlfriend's Sister

Chapter 18: The Truth Comes Out

"Yesterday's clothes weren't tight enough, so when you bent down to ask Yamazaki-sensei a question, you accidentally exposed yourself."

Uesugi Aoi blushed slightly and said somewhat shyly.

"Oh, I see."

Himeno Saki's tone carried a hint of disdain.

"Um... Yamazaki-sensei has been staring at me."

"Ha, staring at it the whole time?"

Himeno Saki crossed her arms over her chest, looking somewhat surprised.

"Saki-kun, this isn't a good idea."

"Ha, you're right. But that's inevitable, after all, Mr. Yamazaki is a man."

Upon hearing this, Uesugi Aoi was overjoyed, feeling that her plan was succeeding step by step as she had envisioned.

Next, all I need to do is express my support for Himeno Saki's relationship and continue to pick out clothes for her that are likely to reveal too much skin.

After being reminded, Himeno Saki Ryo will definitely notice Yamazaki Kazuo's lewd gaze, but because of love, she will not feel disgusted; instead, her heart will become more and more restless.

His wife often leaves Tokyo for business trips, and he only needs to stir things up from the sidelines and then find a suitable opportunity to leave.

At that time, Himeno Saki Ryo will definitely do something outrageous, but what she doesn't know is that her every move will be recorded by her with a miniature camera as evidence.

Seeing Himeno Saki lower her head shyly, Uesugi Aoi decided to go along with her wishes and continue the conversation.

"Yeah. Yamazaki-sensei works so hard teaching us, so it's okay to see some fan service scenes now and then. It just shows that you're very charming, Saki."

"Really? Hehe, in that case, Aoi-kun, why don't you and I wear some cool clothes together? Let's treat Yamazaki-sensei together."

"Saki, Saki-kun, what did you say?"

Uesugi Aoi wondered if she had misheard. In her memory, Himeno Saki was a little silly, but definitely not the kind of shameless person.

"I said, let's wear clothes that show off our figures and compare them in front of Mr. Yamazaki to see who has a better figure."

Himeno Saki looked at Uesugi Aoi with a sinister smile.

"I... I'll pass."

【You really think I'm your servant? Making me accompany you to school is one thing, but now you want me to bring a dowry?】

"Aoi, do you know why I spanked you yesterday?"

Why?

"Because a guy who stares at a woman's cleavage is even more perverted than a man staring at a woman's cleavage!"

Himeno Saki raised her head and looked at Uesugi Aoi with murderous eyes.

"Saki Ryo, you've misunderstood."

Uesugi Aoi, feeling guilty, spoke in a trembling voice.

"The dress I wore yesterday was supposed to have a bow at the neckline to secure it and prevent any wardrobe malfunction. But you didn't put it on for me. I thought you forgot in your haste because class was about to start."

"I didn't expect you to do this on purpose."

"I, I didn't, I didn't mean to."

"You initially hid the ribbon in your pocket, but by the afternoon it was gone. Do you know how I found out?"

"How did you find out?"

It was early morning, and the air conditioning in Himeno Saki's bedroom was at a comfortable temperature, but Uesugi Aoi felt a chill coming from behind her.

"When you stuck your butt out to ask the teacher a question, that ribbon that should have been in your pocket disappeared. You hid it in your room, right?"

A devilish smile appeared on Himeno Saki's face.

Upon realizing that his scheme had been exposed, Uesugi Aoi turned pale and stood frozen in place, not daring to utter a single word.

Because Himeno Saki was right, she only needed to search her own room and close her wardrobe to catch him red-handed.

"Saki-san, I'm so sorry..."

When she realized her plan had been exposed, Uesugi Aoi panicked.

"Didn't Professor Yamazaki say that calling someone 'classmate' in class is so outdated? Don't call someone 'Miss' anymore. You're not my maid."

"Saki-san, I'm sorry, please don't tell anyone about this."

"I understand you. You were having a great time at home during the summer vacation, and then you were suddenly called to class. You must have been feeling terrible. My mom is so domineering; she never considers other people's feelings when she does things."

"Go tell my mother now that you don't want to study anymore. Leave my house immediately, and I'll pretend this never happened."

At this moment, Himeno Saki Ryo actually possessed a hint of the majesty of a matriarch.

"Saki, I'm sorry, please give me another chance. I promise I'll study hard and won't mess around again."

"Do you still want to maintain the 'good girl' persona now? How hypocritical! I'm going to tell your mom and grandma right now that you deliberately didn't let me get dressed properly, making me look bad in front of Mr. Yamazaki."

"No, please! Saki-san, please forgive me."

Uesugi Aoi was so frightened that she immediately apologized from her seat.

Himeno Saki, who had initially intended to get rid of Uesugi Aoi, reconsidered. She realized that her mother would definitely find someone else to supervise her after she left.

In contrast, the stupid and wicked Uesugi Aoi is easier to deal with.

"In that case, I'll give you one more chance."

"Thank you, Saki-kun. I won't do it again."

Uesugi Aoi wiped away her tears.

"Alright, let's not waste time on this boring stuff. Pick me a suitable outfit."

Himeno Saki pulled Uesugi Aoi to the wardrobe.

"Saki, what clothes do you want to wear?"

"Don't be too revealing, or my mom will definitely nag. But don't be too conservative either. My breasts seem to have gotten bigger recently, and if I wear something too conservative, my chest feels constricted."

"Me too."

Uesugi Aoi smiled and then picked out a red and black long dress from the wardrobe.

"How about this one?"

"It looks good, like an outfit a vampire princess would wear. I'll try it on."

After getting dressed, Himeno Saki sat in front of the dressing table and had Uesugi Aoi comb her hair.

"Oh right, Aoi, I forgot something."

"What's wrong?"

"Remember to make a mistake today, and let Mr. Yamazaki hit you."

"Huh? Why?"

"Because I was angry yesterday, I spanked you, which accidentally disrupted class discipline and resulted in Mr. Yamazaki punishing me by hitting my palm. As the culprit behind all of this, you must also be punished."

"I understand. I'll find a way to get Mr. Yamazaki to hit me."

"Remember to make mistakes with your ass."

"What, with my ass?"

"Yes, that way Mr. Yamazaki can spank you."

"But, but how can I make a mistake using my butt?"

"I don't care about that, you just have to make a mistake with your butt and get Mr. Yamazaki to spank you. Otherwise, I'll tell your grandma about what happened to you."

Himeno Saki is like a tyrant, making unreasonable demands on Uesugi Aoi.

"Yes. I understand."

Uesugi Aoi was seething with hatred, but since Himeno Saki had leverage over her, she had no choice but to comply.

【Himeno Saki, you just wait! I'll destroy the evidence right now, and then I'll find a chance to get my revenge on you.】

Uesugi Aoi made a silent vow in her heart.
