Reincarnated as the Promiscuous Protagonist in a Netori Game, Only to Find the Heroine, My Step-Sister, Already Threatened to Be a Submissive Slave~ Liberating the Slave and Planning to Leave Home, Yet Unexpectedly Becoming Loved by My Step-Sister~ - Chapter 24 - The Girls' Temptation

Chapter 24 – The Girls’ Temptation

“Both step father and Mom have a day off today?”

The next day—The morning of Tsumugi’s birthday.

Tsumugi was unusually relaxed in the morning, and asked when she saw the family all gathered together.

“Yes, that’s right~ Today, Genzo-san and I both have the day off~”

“That’s good. I hope you both have a good rest today.”

Saying this, Tsumugi took the initiative and started preparing breakfast.

The rest of us, Mizuki-san, Genzo, and I, involuntarily looked at each other.

Apparently, Tsumugi did not realize that today was her birthday.

But that didn’t change what we were about to do.

Mizuki-san got into the act.

“T-Tsumugi-chan? For today, would you like to go shopping with your Mom?”

The plan is simple and clear.

First of all, Mizuki-san takes Tsumugi out for lunch, and they spend some mother-daughter time…

Meanwhile, Genzo and I prepare for the birthday party.

“Shopping? With just Mom?”

“Yes! Just Tsumugi-chan and Mom~ It’s only once in a while, right~?”

“That sounds like a lot of fun, but… You must be tired.”

“It’s okay, it’s okay! Mom isn’t tired!”

Mizuki-san enthusiastically demonstrates her good health by rotating both hands.

“Then why don’t Mom and step father spend some time together as a couple. You two are newlyweds—”

“I don’t care about Genzo-san right now!”

Genzo, sitting across the table, shivered. His face was grim and he looked sad. I’m sure Mizuki-san didn’t mean that, but I feel a little sorry for him.

“T-Today is Tsumugi’s day!”

“My day…?”

“Ah, n-no, forget it! It’s nothing! It’s really nothing~!”

It seems like the plan is to keep the birthday a secret.

Well, since she’s so unaware, we might as well make it a surprise.

“Is that so…?”

Tsumugi tilted her head curiously.

“Yes, forget it already! So Tsumugi, let’s go shopping with Mom! You’ll come, right!? It’ll definitely be fun! Let’s go!”

“W-Well, if you’re going to go that far…”

Tsumugi nodded modestly.

“Yay~! Shopping with Tsumugi~♪”

“Whoa, M-Mom, please don’t hug me…!”

“Mom can’t help it because she’s so happy~♪”

Mizuki-san hugged Tsumugi happily like a child.

At first Tsumugi was only surprised, but soon she put her hands on Mizuki-san’s back.

“I’m also happy… It’s been a very long time since I went shopping with Mom…♪”

The skinship between mother and daughter was very touching.

All that’s left is to entrust Tsumugi to Mizuki-san until the evening.

I looked at Genzo again and we nodded at each other.

That being said, the morning is a leisurely holiday as usual, with nothing special happening.

With the test coming up in two weeks, it’s time to get to my desk and study.

I have to study hard at home, just like Minase told me to.

Pon♪

I heard my phone vibrate.

It was from Minase.

[Are you studying properly?]

[Just about to start.]

It’s the kind of timing that makes me want to say, “Are you my mother?”

[Your sister’s birthday is important, but make sure you take care of yourself too.]

[I know. Thanks for worrying about me.]

[I’m not worried about you! I just don’t want any students in my class to have to go to supplementary lessons! Good luck!]

Finally, her polite language collapsed.

[I’ll do my best.]

[Make sure your birthday party is a good one, too.]

You’re a good person, Minase.

If my mother had told me to study, I would have lost all motivation, but with encouragement from Minase, I feel more motivated.

I opened my notebook, textbook, and pen at the ready.

Pon♪

My phone vibrated again.

Thinking that it might be Minase again, I picked up the phone.

[Sen~pai~ I played this eroge yesterday, and it was so much fun.]

It was Amatsuyu Kokoa, the bitch junior.

E-Eroge, you say…!?

Ah, I feel so itchy when it comes to eroge talk…

[I’m too lazy to type. Senpai, let’s call. Talk a lot with Kokoa~]

[What’s the title of that eroge?]

[Magic Love ♡ Youth Twinkle.]

It’s another outrageous masterpiece…!

That’s right… Unlike me, who has done my fair share of eroge, Kokoa is still in the process of scavenging for masterpieces.

I want to talk. I want to talk about it…!

[Sen~pai~? Let’s talk. Come on~]

Even through text, she conveyed a sweet and alluring temptation.

“Damn it…!!”

But I have to study to repay Minase for helping me so kindly and not to make my family sad…

With trembling hands, I typed on my phone.

[Another time.]

[Ehh! Why!?]

[We’ve got a test coming up. You should study hard too.]

Even though she’s a first-year student, she’s the kind of person who would skip school because of eroge.

[Eh? You can get good grades on tests just by listening in class without studying, right?]

[You haven’t even been in class recently.]

[I mean you should just listen to the class before the test. Most of the teachers will review the test material for you, and the test will be easy.]

Is she…a genius…?

They say that you can’t have two things at once, but it seems that doesn’t apply to beautiful girls.

[Goodbye.]

[Eh!? Senpai!? Sen~pai~!?”

I cut off the conversation with Kokoa.

Let’s maintain a healthy friendship with her, focused on just eroge. I won’t bring up the topic of studying again.

I picked up my pen for the third time.

Pon♪

“Not again, what now!?”

I opened the message.

[T-Takuma-san… This is the new me…]

“—Buhuh!?”

The message was accompanied by a single image.

A naughty selfie of Mayoi Yura boldly exposing her breasts… They’re really big…

Thanks to the recent visit to the beauty salon, her level of attractiveness has increased by 70%.

[How do I look…? Do I look cute? Do I look sexy? Please praise me a lot, Takuma-san♡]

[Don’t send me pictures like these again.]

I Immediately cut off the conversation.

After that, I grabbed my smartphone and headed to the bathroom…

……

…

Around noon, Tsumugi and Mizuki-san left for an outing as scheduled, looking very harmonious and affectionate with each other.

Just as I was thinking about starting my own preparations—

“Takuma, are you there?”

Genzo came to my room a little earlier than expected.

“Dad? What’s up? It’s still too early to start preparing…”

I said after opening the door, thinking it was unusual.

There, as usual, stood my father, with a furrowed brow and an anxious expression, wearing his usual stern face.

“Takuma…”

“W-What?”

He looked so worried that even I was becoming nervous.

“What should I choose for a daughter’s birthday present…?”

Now it’s already too late!!!

After having struggled with the same issue myself, I felt the urge to shout out in frustration.
