My Sex Friend Is My Childhood Friend? - 8-9

Chapter 8: The Relationship Between the Two

ーーーーーーーーーーーーーーーーーーーー

When I got to the office, my senpai interrogated me thoroughly. Apparently, he had stayed late to cover for me yesterday. I figured I’d have to tolerate a bit of privacy invasion, or karma might bite me.

I’m really grateful. Senpai, you’re a jerk, but I love you.

Senpai asked.

“So, you guys didn’t exchange photos or anything beforehand, right? What was she like?”

I answered honestly.

“Well, she was way beyond my imagination. Not just cute, but somehow…Comforting. Like she reminds me of someone. Her eyes are so big and round.”

Senpai looked kind of frustrated.

“And, did you do it?”

Feeling good, I crossed my arms.

“Oh, yeah. Her body was amazing too. I think I got six months’ worth in two days.”

“Damn, that’s wild. Staying over right after meeting? You’re young, huh. Did you have enough condoms?”

“The ones provided ran out quick, so after that, we went without…”

“Seriously? Aren’t you worried about diseases?”

“Somehow, I just felt like she’s fine. She didn’t seem like the type to mess around.”

Senpai lowered his brows and gave me a “you’re hopeless” look.

“Dude, are you stupid? A girl you can sleep with on the first meeting isn’t exactly ‘safe.’ You better be careful. But if she’s got a great face, body, personality, and is good in bed, she’s perfect as a sex friend. Save the romance for someone else and treat her well~”

Talking with senpai brought me back to reality.

Yeah, that’s right. We’re just sex friends.

Mahiru was so kind and being with her felt like I had a girlfriend, so it was easy for me to get the wrong idea. But still, expecting something out of a girl? Again? I really didn’t want that. 

A girl like her doesn’t come around often. I doubted I’d get interested in other girls after knowing her. 

A week passed, and I didn’t hear from Mahiru. I felt hesitant and didn’t contact her either. But there wasn’t a single day I didn’t think about those two days with her.

She’s cute, like a girlfriend. But no, it’s different Haah…

I kept having that internal back-and-forth. Truth was, Mahiru hadn’t healed my distrust of women. No matter how cute she was, this superficial relationship was probably for the best. Another week went by without contact, and I started thinking.

Maybe this is the end?

Then, one day, Mahiru messaged me. I opened the messenger, and it was just one short sentence.

『I want to have sex.』

I was happy to hear from her, but that one line hit me with reality and made me sad. It felt like I was the only one getting carried away. But I was the one who wanted a friends-with-benefits relationship. Mahiru did nothing wrong.

With that in mind, I replied.

『Got it. So, when’s good for you? I’m thinking of one of the weekend days? And I’m also thinking of bringing a car. Is that okay with you?』

She replied right away.

『Yes. Saturday works for me. Let’s meet at xxx. I’m a bit nervous about the car, but if it’s with Onii-chan, it’s okay.』

And so, I made plans to meet Mahiru again.

Chapter 9: Still, In the End…

ーーーーーーーーーーーーーーーーーーーー

The following Saturday. I woke up early in the morning and washed the car. Then, I went to pick up Mahiru.

When Mahiru got in, she was wearing a coffee-colored checkered shirt and loose denim pants. The knit under her shirt revealed a glimpse of her slender waist. The black cap she wore low suited her perfectly.

It had been a while, but as expected, Mahiru was adorable. After a short drive, we checked into a hotel. Once inside, Mahiru instantly became clingy, sticking close to me.

I realized I had forgotten about lunch.

“I’m getting a bit hungry. Should we order something?”

Mahiru rummaged through her large bag and pulled something out.

“Here. A bento. I felt bad for making you spend so much last time, so I made this. Will you eat with me?”

When she opened the bento box, it contained octopus-shaped sausages, sautéed spinach, tamagoyaki, and onigiri. Simple, but a homemade bento.

Come to think of it, this might be the first time a girl made something like this for me. I always turned it down before, worried about giving the wrong impression.

Mahiru fed me with an “Aah.” It felt a bit embarrassing, like we were beyond a couple and more like newlyweds, but I let her feed me. Of course, there was no frozen food, and the salmon in the onigiri was properly flaked from grilled fish.

After we finished eating, I thanked Mahiru for the bento.

“It’s delicious. Whoever becomes Mahiru’s husband is gonna be a lucky guy…”

Before I could finish, Mahiru pressed her lips against mine. Pulling back, she said in a slightly trembling voice.

“Let’s not talk about that right now.”

Then, she pushed me down onto the bed. While slipping off her shoulder straps with a hint of shyness, she said.

“Onii-chan, you like it natural, right? It’s okay. I showered before coming, so we can go as is.”

“No, I’m the one who’s sweaty from washing the car this morning… I’d like to shower first.”

Mahiru’s eyes lit up like a puppy spotting a toy.

“You washed the car… For our date, for our promise. I’m so happy! Well then, I’ll clean Onii-chan up with my mouth…”

Mahiru knelt in front of me. And, just like last time, I was toyed with and ravaged. This time, though, having held back since we last met, it felt like it was over even faster.

“…Ngh!”

Mahiru let out a surprised sound. After calming down, she looked up, licking her lips with her tongue.

“I almost choked on all of Onii-chan’s stuff. It’s delicious today too. Hey, I still want some too. Give me seconds.”

With that, Mahiru straddled me.

“Wait, back-to-back is…”

Ignoring me, Mahiru licked my neck while moving her body back and forth, rubbing against me.

When a girl this cute begs like that…

Apparently, my body was up for the challenge. I underestimated myself. Sorry, me.

That day, we went at it for what felt like months’ worth, and I drove home dizzy. I dropped Mahiru off at a convenient station and headed back in the car. While gripping the steering wheel, I thought about Mahiru.

Mahiru is such a great girl and she’s smart too. She anticipates things that might make me uncomfortable and avoids saying them, and she picks up on my intentions even when my words fall short. Honestly, it’s hard not to fall for her. But because she’s such a great girl, I couldn’t help feeling distrust.

Why would a girl like her want a friends-with-benefits relationship? If she wanted a boyfriend, she could get one in a heartbeat. So, what’s her deal?

Before I knew it, I was already crossing the line of being just friends-with-benefits. Each time, I looked at Mahiru’s short message.

『I want to have sex.』 

Yeah, she’s not looking for anything more than this. I need to keep my place in check. Our relationship is built on the promise that it ends if either of us catches feelings after all.

I told myself this as I drove home.
