My Sex Friend Is My Childhood Friend? - 10

Chapter 10: My Sex Friend Is My Childhood Friend

ーーーーーーーーーーーーーーーーーーーー

Mahiru would contact me on a whim, and we’d meet up from time to time. That kind of relationship went on for a while.

When I was with Mahiru, she was really cute and sweet. I almost forgot the reality of our relationship every time we met.  Whenever that happened, I’d go back and reread our messages.

Our exchange mostly consisted of Mahiru’s 『I want to have sex.』 and our meeting arrangements. Seeing those purely business-like exchanges would bring me back to my senses. I wondered how long this kind of relationship would continue.

But, well… I figured I’d keep going along with it until Mahiru got bored.

Then, as usual, a message came in saying.

『I want to have sex.』

And like always, we arranged a time and place to meet. Only, this time there was one thing different. I had something to do in the morning, so I couldn’t meet Mahiru until the afternoon.

After we met, we spent time together at a hotel like always. Even though I had thoughts about it, I didn’t say anything. That was just the kind of relationship we had. Besides, when I was with her, I felt strangely calm, like all my worries disappeared. It was odd.

But maybe I was lost in thought more than usual. Mahiru kept peeking at my face or cuddling up to me like a cat trying to cheer me up. Even though it wasn’t her fault, she was still being considerate of me.

What the hell am I doing? How can I expect anything from Mahiru when I can’t even face myself?

I couldn’t control my emotions properly. Maybe it was time to end this. Maybe Mahiru, who always picked up on what I was feeling, sensed what was going on inside me. She kept holding my hand, trying to set up the next time we’d meet. That had never happened before—we never made plans while we were still together.

Even so, when I opened my mouth to speak, Mahiru kissed me, silencing me. Then, without taking off her skirt, she just slipped off her panties and climbed on top of me.

Today, Mahiru was more daring than usual.  It felt like her body was instinctively seeking my genes, and against my heart’s hesitation, my body became aroused. But the more effort Mahiru put into it, the more my internal contradictions grew. Before my feelings and body could reach their peak, I opened my mouth.

“Hey, Mahiru. Maybe we should end this soon…”

Then Mahiru began to move intensely.

“No. I don’t want that. I don’t want to stop seeing you. Please… Come inside. Fill me up.”

“…What?”

I gave in to the impulse and came inside her. And I got so turned on that we ended up doing it three times in a row after that.

What the hell am I doing? Wasn’t I just about to end our relationship?

Still, at the very least, I knew that Mahiru also wanted to see me. And the fact that I might’ve gotten her pregnant now… There was no way I could just walk away like that. That would be completely irresponsible of me. I had to be satisfied with things the way they are for now.

At the very least, I couldn’t continue that conversation until Mahiru got her next period.  After we were done and lying on the bed, Mahiru rubbed her stomach happily. Then she said, sticking out her tongue playfully,

“I’m sneaky, aren’t I?”

I forced a smile.

“You really are.”

Mahiru pouted a little, then pressed herself against my arm.

“But… I want to stay like this for a little longer. Right now, I don’t think I can handle being alone. And, you know… Onii-chan is so warm and gentle, and you’re all inside me… Mm, I’m starting to feel weird again…”

Saying that, Mahiru squirmed her legs and clamped my thigh between hers. Then she started touching herself with the middle finger of her right hand, eyes glazed over and watery. Mahiru leaned in and kissed me again. As our lips parted with a sigh, saliva stretched between them like a thread.

“Hey. I want more. Love me more…”

After that, all my earlier anxiety vanished. We ended up breaking our own record for how many times we could go in a single night.

Riiing! Riiing!

…Crap. I fell asleep. It was already past the time for the last train. I woke Mahiru, who was clinging to my arm and sleeping soundly.

“Mahiru, wake up. Sorry, I have work early tomorrow, so I can’t stay over tonight. The closest station is… No, it might be dangerous walking at night. If you don’t mind, I’ll take you all the way to your house.”

Still half-asleep, Mahiru asked for a kiss.

“Mm, it’s okay. I trust you, Onii-chan. I’ll tell you my address later. And also…”

Mahiru looked into my eyes. She blinked a few times, then gently bit her lower lip. Her voice was so soft, it made me want to ask her to repeat it.

“And… Will you see me again?”

I felt the corners of my mouth lift into a smile.

“Yeah. I will.”

Mahiru hugged my shoulder and looked up at me from under my chin. Then she smiled. It was a big smile that made the corners of her eyes crinkling.

“I’m glad. Also, I have really bad period cramps, so I’m on hormone medication. So… I can’t get pregnant.”

“…What?”

Mahiru stuck out her tongue like a mischievous child.

“See? I really am sneaky, right?”

Seriously, this girl.

I gave her a wry smile.

After that, I hurried to get her home. Mahiru had been holding my hand the whole time since we left the hotel. Honestly, I felt like we were closer than most couples going through a dry spell. But she never asked for anything more.  I really didn’t understand what Mahiru truly felt.

Mahiru gave me her address.

“Tokyo, XX Ward, XX Town…”

…Wait. That’s the town I lived in until middle school.

As we got closer to Mahiru’s house, the scenery became more and more nostalgic.

“That house right there.”

Following her instructions, I parked the car. It was right in front of a house I knew well.

This was the home of Maya Hatsuharu, the childhood friend who left me with a deep trauma and a distrust of women. While I stood there, dumbfounded, Mahiru spoke to me with a worried expression.

“Onii-chan, what’s wrong? Thanks for bringing me. …Um, will you see me again?”

“…Yeah.”

Honestly, I was unsure how to respond, but I was too stunned to even think straight.

“I’d like to see you on the first Saturday of next month.”

Mahiru said while waving goodbye to me. She then bowed neatly with both hands on her knees, before walking into the house. She looked back at me a few times until she finally disappeared into her house.

I stood there in shock for several minutes. Then, the face of the girl who once looked down on me and said “Gross” back in middle school flashed in my mind.

…No, her face looked different now. That girl didn’t have such pretty double eyelids. She wasn’t that well-proportioned or busty either. Her hair was short and black. Her voice… Maybe it was a bit similar. But she talked more like a boy, right? What was her name again?

My childhood friend was named Maya. My current sex friend was named Mahiru. If you write “Mahiru” in kanji, it’s “真昼”—”Midday.” And Maya was “真夜”—”Midnight.”

Mahiru and Maya. She just flipped her real name for her username. I was sure of it. She was the girl who crushed me…My childhood friend.
