My Adopted Family

"Sister. I will try."

Unable to bear my frustration, I ended up disobeying my sister's order to lie still.

I stood up and lifted my older sister, who was crouching over me.

"Ouch."

At my sudden action, she let out a cute scream that wasn't typical of my older sister.

If it were me, it would have been impossible to lift my sister in this uncomfortable position with just my elbows.

But right now, I'm pumping out the highest amount of adrenaline in my life. It felt like I could lift a truck right now.

I just turned my sister over.

My sister became prone in front of me.

As she got down on all fours, her short skirt naturally rolled up.

The panties had already been taken off, so there was nothing covering my sister's important parts.

Light red flesh split vertically is visible. As a sister who likes things neat, there wasn't a single strand of hair visible.

Between the white, round buttocks was, the cute anus, slightly darker than the color of the skin, was fully exposed.

What kind of scenery is this?

My heart feels like it will explode. Maybe I've been living for this moment.

"Wait a minute, this position… … !"

Meanwhile, my sister seemed very embarrassed by the unplanned change in posture.

She quickly stretched one arm back and covered the hole near her buttocks with her hand.

She doesn't shy away from showing her pussy but she doesn't want to show her backhole.

Normally, the more she hide something like this, the more I want to see it, but that's not important right now.

Right now I'm on the verge of going crazy because I want to put it.

"The first time you do it, it usually doesn't go in well, so it's easier to put it in by doing it backwards like this. It hurts less."

I learned from the Internet. I don't know if that's true. Anyway, it's my first time too.

But since it's my sister's first time, we both don't know anything.

What matters is not whether it is true.

To put it simply, it was important that I take the lead in this action.

Not the position my sister wants, but the position I want.

As always, my sister tried to take the lead this time, just like she has been putting me down and doing whatever she wants. However, my sister couldn't properly take my cock in, and the initiative passed to me.

And I had no intention of just handing over the initiative that I had taken so long to gain.

There is no place for my sister to escape to on the narrow bed.

"Sister. I'm putting it in."

I grabs both of my sister's plump buttocks and pushes my waist into thrm .

My cock, filled with blood to its maximum, becomes a hard spear and penetrates my sister's tightly locked vagina.

"Oh!"

My older sister was embarrassed and tried to run away by crawling on all fours, but I didn't let go.

Because I was holding on tightly with both hands, only her hips were shaking slightly. As if tempting me.

As the spear-like glans penetrates, my sister's pussy, which had been closed tightly like a clam, gradually opens. My glans hid it head inside my sister.

"Huh!"

My sister takes a deep breath. She trembled under the frightening pressure.

My sister's insides were hotter than I thought, and she squeezed my dick so hard that it hurt.

It feels like all the blood in my body is rushing towards the area where I am in contact with my sister. All my attention was focused on the tip of my cock.

I was half-fazed and dug deeper.

"Ssssssssssss…!"

My sister gritted her teeth and moaned as if she was enduring pain.

My sister's virgin hole is extremely tight.

The hole was too narrow to completely swallow my large object. 

It felt like forcing an incorrect key into a tightly locked lock.

A thought crossed my mind as to whether I should have caressed it more and made it wet.

But now there was no way I could afford to caress.

Right now, the only thought in my mind was that I wanted to shake my waist and rub the inside of my sister's vagina.

I wanted to quickly let out this boiling desire.

"Ah, ah!"

I put further in.

The deeper I went, the more my sister let out a weak, girlish scream.

My older sister's femininely curved back was trembling.

My dick gradually disappeared from the tip inward.

Suddenly, my lower abdomen came into contact with my sister's buttocks.

It went in to the maximum that could physically go in.

A feeling of pleasure as if lightning had struck the top of my head and flowed down my spinal cord.

My spine trembled. 

"Ugh… … ha… … ."

A great sense of conquest. I shuddered with emotion.

It felt like I was having a ridiculous dream.

I finally hugged my older sister, who was the object of my admiration.

They say imagination is free, but I was so sad that I couldn't even imagine it.

But, I ended up doing something like that in real life.
