The Beautiful Senpai from the Archery Club Is Sleeping in My Room with Her Stomach Exposed. - Chapter 16: Watanuki-Senpai's "Second Form" is Quite Bold.

Watanuki-Senpai’s “Second Form” is Quite Bold.

It has been a week and a few days since Watanuki-senpai started visiting my house after club activities.

Despite such a short period, my daily routine has already undergone some changes.

“Oh, Rino-chan, welcome! Thanks for stopping by after club activities!”

“Good evening, Mei-san. Here, some side dishes as a gift. My mom insisted I bring them.”

“Wow, that’s so kind of you! Our dinner table just keeps getting more lavish.”

From the entrance, I could hear the casual exchange between Watanuki-senpai and Mei. It seemed like the two had gotten considerably closer over the past week.

After club activities, Watanuki-senpai would first stop by her home, take a shower, change into casual clothes, and then come over to the Amemoto household. This had become a new routine.

“You’re tutoring Touya  again today, right? Lucky! I wish I could get lessons from you too, Rino-chan.”

“Fufu, I’m not good enough at studying to tutor someone my own age. I’m only doing this because it’s Amemoto-kun, and I owe him.”

Nice excuse, Senpai.

That was the explanation given to the Amemoto family—that I was struggling with my studies and had asked Watanuki-senpai for help.

This reasoning justified her frequent visits, and even my busy mother, when she was home, was welcoming, often thanking her for helping her son.

“I see… I guess there’s no room for me then. Well, enjoy your time alone together.”

“…U-uh, yeah. I’ll just relax.”

“Oh, but no flirting! If I hear any lovey-dovey sounds coming from my little brother’s room, I’ll burst into tears and start howling, you hear? Grrr!”

What kind of assumption is that? No, there will be no flirting or anything remotely close.

I almost felt compelled to interject from my room, overhearing their conversation at the entrance. After all, by contract, my only role was to support Watanuki-senpai and help her as needed.

A few minutes later, I heard the light, rhythmic steps of someone climbing the stairs—without a doubt, Watanuki-senpai.

Then, the door to my room quietly creaked open—only for the visitor to swiftly collapse onto the beanbag chair on the floor.

“Exhausted… The journey here was brutal. My cells are telling me that I need to rest in your room right now… Can I take a nap?”

“However, napping after 8 PM may negatively affect sleep quality. Let’s get started with today’s study session, Senpai.”

“You’re really a demon, aren’t you…?”

Coming from someone who’s naturally mischievous, that’s not something I want to hear.

She gave me a half-lidded stare, but I ignored it and pointed to the study materials neatly arranged on the low table.

Alongside notebooks and pencils, a second-year reference book was already prepared. A warm cup of green tea was also waiting.

Yes, the ‘study session’ explanation we gave Mei and my mother wasn’t just an excuse for Senpai to come over.

“We’ll switch off only after today’s quota is completed. Looking forward to another productive session, Watanuki-sensei.”

In reality, I was genuinely learning from her.

Since I had nothing to do at home after school, I had taken it upon myself to complete the entire first-year curriculum in my spare time. So, with a bit of guidance, I could keep up with second-year material just fine.

For Watanuki-senpai, teaching me served as an efficient way to review her lessons. With my presence, she no longer overworked herself without taking breaks.

Just a few days ago, she had cheerfully mentioned, “Thanks to this, I’ve been able to reduce my study hours and create more free time!”

But today—

“I’ve reached a point where just seeing your face switches me off… I don’t want to move. Would it be possible for you to study on my behalf while I take a nap?”

“Even fairy tale elves wouldn’t be up for that task. Come on, sit up.”

“Ehh… Help me up.”

Still hugging the beanbag chair, she held out both arms toward me. W-what does she expect me to do? Pull her up?

Ever since she started coming here, she had become increasingly lax—relying on me more and more.

I had no choice but to grasp both her hands and attempt to pull her up, but sadly, my strength wasn’t enough. No matter how hard I tugged, she barely budged. Instead, she let out a playful shriek, burying her face deeper into the beanbag.

“This isn’t some kind of human-powered amusement ride. Come on, get up already.”

“If you don’t pull harder, I won’t be able to stand, you know?”

“A fully relaxed human body is heavier than you’d expect. My arm strength isn’t enough to counter your weight.”

“Ahh! That sounded like you just called me fat! Not okay at all! You should check properly—I’m still slim, you know?”

Before I could react, she swiftly let go of my hands and instead grabbed my wrists.

What—a counterattack?

She used her strength to guide me down into a crouching position, closing the distance between us.

Then, she led my hands to rest around her waist.

The moment I touched her, I was startled.

“…This is—”

Indeed, she was slim. Even through her casual clothes, I could feel how incredibly toned her midsection was.

Wait, her organs are really in here? My mind couldn’t process it.

My fingers reflexively moved as if to confirm the presence of something beneath the surface.

Even through the fabric, her skin was soft, yielding slightly under the touch.

“Nngh… That’s… beyond what I expected…”

“Ah—s-sorry…!”

Apparently, that action wasn’t permitted. She looked up at me, slightly embarrassed.

I messed up. Even if it was unconscious, I had definitely crossed a line.

“…”

“……”

An awkward silence filled the room.

What is she thinking right now? With her face turned away, I couldn’t read her expression.

Then, with a small clap of her hands, she suddenly stood up straight.

“Sorry, I got carried away. No matter how relaxed I feel in your room, I need to stay focused. The midterm exams are approaching, after all.”

“Y-yes, exactly! Please teach me what you learned today, Senpai!”

“Leave it to me. In fact, I took today’s notes specifically to teach you.”

“I’d rather that not be true… Hahaha…”

As expected from the captain of the archery club, she recovered quickly. Meanwhile, my own words still felt awkward and forced.

It was my first time touching a girl’s stomach—of course, I had never even done that with Mei. The unexpected softness had thrown me off completely.

Even now, as she sat across from me, ready to start, the faint sweet scent of her post-shower hair caught me off guard. My heart skipped a beat.

I thought I had gotten used to Watanuki-senpai, but I still couldn’t feel at ease. Even though this was my own room.

What do I do? I shouldn’t be flustered when I’m the one supporting her. That’s inappropriate.

Calm down… I took one, two, three deep breaths. Okay. The inexplicable excitement had faded.

After all, I had trained myself to control my emotions ever since that competition failure.

“Phew… Alright, let’s get started.”

“Yes, let’s quickly finish today’s study session so we can enjoy some free time together. There’s a manga I want to read with you.”

While being careful not to get too emotional about Watanuki-senpai’s soft smile and calm attitude, I opened my notebook absentmindedly.
