My Sex Friend Is My Childhood Friend? - 44-45

Chapter 44: Mimura-senpai’s Younger Sister

ーーーーーーーーーーーーーーーーーーーー

After that, Aoi and I started exchanging messages from time to time. Aoi would message me about her part-time job, school life, and various things from her daily routine.

Apparently, her name (Asoi) was written as 蒼依. With a name that rare—both first and last—you’d really have to live carefully. No way to get away with trouble.

I replied to Aoi’s message. There was one thing I wanted to ask her.

『By the way, that diamond-shaped keychain… Aoi-chan, do you like that character?』

『No. That was from my Onii- I mean, from my big brother.』

That keychain was the same one I’d given to my senpai years ago. It featured a character from an anime that aired a few years back—one you couldn’t get in stores anymore. So Aoi really was the younger sister of Mimura-senpai.

Back in high school, I was completely fed up with everything and ready to throw it all away. That senpai had given me a wake-up call and turned things around for me. If I hadn’t met him, I probably would’ve dropped out of high school. But things happened, and after he graduated, we lost contact.

I wonder what he’s doing now.

I tried asking Aoi, but whenever we talked about her big brother, Aoi became all evasive. She kept dodging the question and wouldn’t give me a clear answer.

I wonder what’s going on?

If Mimura-senpai were to get caught in trouble, I wanted to help him if I could. I really couldn’t help but worry about him. Still, it seemed he was doing okay for the most part, so maybe I shouldn’t pry too much.

Maybe it was something related to her family. Of course. There were things she couldn’t talk about with a stranger like me. Aoi was a second-year high school student, and she had entrance exams next year.

When I told Scum Senpai about Aoi, he teased me.

“You’re banging a high school girl now? So jealous~”

I didn’t think Aoi disliked me, but I didn’t want to get arrested either. Besides, I had Mahiru. Aoi was more like a little sister to me. And that little sister and I had plans to go shopping tomorrow. She wanted my help picking out a birthday present for her brother. He was someone I owed a huge debt to—this was the least I could do.

We agreed to meet at the nearest train station over the weekend. I got there five minutes early, and Aoi was already waiting. She wore a black one-piece dress with frills and gathers, a large black ribbon on her head and another on her back.

Her makeup and hair color matched the dark theme of her outfit, and her lipstick was black, too.

With all the lace detailing, she looked exactly like a gothic lolita, but the look really suited her sharp, almond-shaped eyes. It looked good on her.

I had mentioned once that my favorite anime character wore gothic lolita outfits. Maybe that was why she dressed this way?

Still, youth was amazing. No matter what they wore, it worked for them. Honestly, I was a bit jealous.

“When you go out, do you always dress like that?”

Aoi turned away and replied in a small voice.

“Not usually.”

We walked side by side toward the shopping mall. On the way, several guys turned to look back at her. I wasn’t sure if it was because of her flashy clothes—or her cuteness. …No, I was 90% sure it was the latter.

We chatted as we walked. Since we were buying a gift, I wanted to know what kind of thing she had in mind. She said she was thinking of getting loungewear.

I felt a little off about that. Back in high school, her brother was active and cheerful. He seemed like the type who’d be happier with sportswear than pajamas. And the size Aoi was looking at felt quite a bit bigger than I remembered.

But then again… People naturally fill out with age, and everyone needs something to wear around the house.

I must be overthinking it. We picked out loungewear together. She had me try on a few things and laughed out loud every time. Eventually, we found something she liked, and to take a break, we got some crepes.

While we were eating, apparently I had some whipped cream on my mouth. Aoi reached out, wiped it off with her finger… And then licked the cream. Even though there was no one else around, Aoi leaned in close to my ear.

“I might look like I mess around, but… I’m actually a virgin.”

…Huh? What is this girl saying?

That came out of nowhere. While I was still flustered, Aoi let out a soft giggle. Then she asked me.

“Nagi-san, do you have a girlfriend?”

Chapter 45: A Twist No One Saw Coming

ーーーーーーーーーーーーーーーーーーーー

I was a bit surprised by the unexpected question, but I answered honestly without trying to lie.

“Well, I do have someone I kinda like.”

In response, Aoi hummed to herself. 

“Hmm.”

She placed her hands on her hips, and began circling around me with a half-lidded gaze.

“‘Kinda like,’ huh… So you’re saying I still have a chance?”

Even when I tried to deny it, she went ahead and convinced herself otherwise. It was like my opinion didn’t matter at all to her.

After we finished shopping, I parted ways with Aoi. She kept smiling and waving at me, turning back multiple times as she walked away. Still, she was way too different from the cold, unfriendly image she gave off at the convenience store.

Well, then again, depending on how you look at it, maybe that kind of personality is ideal for a girlfriend. After all, she’s incredibly unfriendly to everyone else. I guess that’s what you’d call a “tsundere”?

She was the complete opposite of Mahiru, who always acted cheerfully with high energy that was borderline exhausting to see no matter who she was dealing with. On the way home, I stopped by the supermarket to do some shopping.

Mahiru had told me to pick up chili bean paste, tofu, and green onions because she was making mapo tofu. When I opened the front door, Mahiru greeted me. I had already told her, honestly, that I was going out to buy a gift on behalf of the younger sister of the senpai who had helped me in the past, so there shouldn’t be any problem.

And yet, for some reason, Mahiru told me to sit in seiza. Then she started asking questions. Mahiru was smiling. She was smiling, but her eyes didn’t look like they were smiling.

It was kind of scary.

“Is she cute? Answer with YES or NO.”

Hmm. How was I supposed to answer that? If I tried to dodge the question, I’d probably be grilled for dodging it.

“…YES.”

Mahiru narrowed her eyes and let out a flat hum.

“Hmm. Then, who’s cuter—me or her?”

When it comes to questions like this, hesitation equals guilt. A quick answer is crucial.

I replied immediately, with a clear tone.

“It’s you, Mahiru.”

Mahiru smiled brightly. Thank goodness. It looked like the interrogation was over. Mahiru sniffed me thoroughly from head to toe, and only then did she seem relieved.

Is she some kind of wild animal?

After that, Mahiru pounced on me. She took off my jacket and started licking my nipples. She kept coming at me over and over again, and somehow, she felt more intense than usual. It turned out, Mahiru was the jealous type. This was a new discovery indeed.

Afterward, we ate dinner together, drank some alcohol and watched a movie. It was a fun evening. Around the time I started thinking about heading to bed, Mahiru invited me out on a date.

“Hey, wanna go see the fireworks next week? I looked it up, and apparently there are quite a few fireworks festivals in May. It’s almost your birthday, right? I wanna celebrate with you.”

So it had already been a year since I got dumped before I even had the chance to confess at that theme park. 

Time really flies.
