6 - A Promise With My Cute Little Sister?

Chapter 6: A Promise With My Cute Little Sister? ーーーーーーーーーーーーーーーーーーーー

In the end, my little sister’s hand was touching my thing directly. Her hand’s movement was awkward and timid as she stimulated me in up and down motion. I was being assaulted by a sensation I had never felt before.

I wonder, who was it the one that said we need to stop doing lewd things? Can that person take my place right now and endure this predicament?

“Don’t… Natsumi…”

But my voice fell on deaf ears. My voice sounded so shameful as I drowned in the pleasure.

“Tell me when you’re about to come. You mustn’t let it out without permission, okay?”

I could feel my little sister’s secret excitement behind her composed voice.

“What about the no lewd things we talked about last night….”

“But this is not lewd. It’s morning so it can’t be helped.”

Could it be, she was mixing up “morning wood” with “wet dream”? I knew that our knowledge about the opposite sex tend to be biased but…

“You’re so hard, onii-chan. And you keep on twitching.”

“Sto-Stop with your live commentary….!”

My little sister’s grip on me tightened and her movement became even faster.

Crap! Crap! I’m already at my limit!

“I’m coming, Natsumi! I’m going to come real soon!”

“Let it out, onii-chan.”

I became even more aroused upon hearing my little sister’s voice.

“Coming!!”

At that moment, I was suddenly enveloped in something soft and warm. I twitched, coming in steady rhythm in my little sister’s mouth. I was ejucalating so hard that my urethra felt sore.

“Natsumi, you….”

She separated her mouth from my thing and then, she gulped my sperm down accompanied by a muffled voice.

“Onii-chan, you came a lot. Besides, I feel like this batch is thicker than yesterday’s.”

I couldn’t help but to smile wryly at her carefree smile.

“It tastes bad, right? Moreover, it’s dirty.”

“It’s not good but it’s not dirty either. It feels so lewd…. Ah, no, I mean….”

I felt like her real intention was slipping out but my little sister still continued trying to deceive me.

“Now it’s my turn.”

I tried to get up but my little sister prevented me from doing so.

“You can stay laying down, onii-chan.”

“But how am I supposed to…?”

Without answering, my little sister unbuttoned her pajamas, exposing her underclothes. But it seemed she wasn’t wearing anything else underneath that.

“Onii-chan, do it like this.”

Getting on all four, my little sister positioned herself so that her breast was hanging right in front of my eyes.

“Onii-chan, please…..”

There was a faint scent of sperm mixed together in her sweet breath. I then started massaging her breast through her underclothes.

“Onii-chan? Are you not going to suck it?”

My little sister said so while fidgeting restlessly.

“Yesterday when we were in the bathroom, it occurred to me that it will come out better after I massage it.”

When I started carefully rubbing the area around the nipples, my little sister started fidgeting even more.

“Onii-chan, you’re so perverted. Stop teasing me….”

My little sister then dropped her ass on top of my stomach and then she started slowly rocking her hips back and forth.

“I-I got it. I’m going to suck them now.”

My little sister’s ass was hitting on my thing, that had become very energetic before I knew it.

“Hurry up, onii-chan. We’re going to be late for school.”

“I said I got it already. Just be quiet for a bit.”

Putting my hand on my little sister’s back, I brought her nipple to my mouth.

“Onii-chan, it’s coming out a lot. I think.”

Certainly, there was more coming out compared to yesterday.

“The other one too, onii-chan.”

I sucked on both nipples alternately and continued on until she gave me the green light.

“Are we done now?”

“Yeah. Thank you, onii-chan….”

My little sister got up from the bed and was about to leave the room when she turned around and said with an extremely serious expression on her face.

“Today, you have to come straight home, okay?”

“Okay, I don’t have anything special to do anyway…”

“I see. Good then.”

A faint smile could be seen on her face.

“You should get up now.”

My little sister added, as if everything that had happened so far was just a dream.
