My Adopted Family

83. S*x With Older Sister



"Ha, ha, ha."

My sister was lying face down and breathing hard.

My older sister is a professional sports player.

Even if she run 100m at full power, her breathing does not become disturbed to this extent.

That means the shock of losing a virgin was so great. As a man, it is a pain I will never know.

"Sister, are you okay?"

My sister never shows weakness in front of me.

She always try to look confident, resolute, and perfect.

But now my older sister is suffering like this.

Even though my dick was taking over my brain, I was worried.

"eww… Ugh… … ."

Instead of answering, my sister just moaned.

It was a voice that sounded like crying.

Is it so painful that she can't even speak?

Guilt becomes a small thorn that pierces my heart.

But I didn't have the option of quitting here.

Because it felt so good.

I wanted to make my sister feel at least a little bit more comfortable, but I couldn't help it.

"sister. I'll move." 

Without waiting for my sister's answer, I pulled her waist.

My sister's vagina was biting my cock hard as if it would never let go, and my cock, which was stuck there, scratched out my sister's inner flesh like an arrowhead.

"Hmm!"

My sister makes a sound as if she is in pain.

My sister's pain is my pleasure.

The pleasure that makes my brain burn stimulates me.

It was unbelievably good.

So much so that I can't think of anything else.

"Ah, ahhh… … !"

My sister completely collapsed in just one round trip.

She buries her forehead in the bed and writhes as if in pain.

The hand that was covering her butt hole suddenly fell away and was gripping the bed sheet tightly.

"Sister, your voice is too loud. What are you going to do if someone came in?"

"Ah, haa… !"

As if she couldn't hear me, she just made meaningless noises.

Anyway, I'm really worried. Could it be heard outside? 

What if the nurse or doctor finds out?

"Sister, I'm sorry."

In my haste, I balled up a small piece of cloth nearby and forced it into my sister's mouth.

"Ough!"

Those were the panties my older sister had just taken off.

Even though it was a last-minute solution, it was an act of tyranny that I could not even imagine.

My sister is so stubborn that she won't even touch an unsealed drink.

I stuffed the panties she was wearing into my older sister's mouth.

It is blasphemy.

My sister might try to kill me for this alone.

But by the time I attacked my sister from behind, it was as if I had already committed a mortal sin.

If my sister tries to kill me, I have no choice but to die quietly.

Still, I'm glad I was able to have sex with the older sister I admired before she died.

"Ugh!"

I hugged my sister, who was lying face down, as if covering her back.

A mysterious body where firm muscles and feminine softness coexist.

A body so noble that it cannot even be compared to mine struggles helplessly beneath me.

I held my sister's breast with one hand and covered her mouth with the other.

She was tightly restrained in my arms so that she could not escape.

"Ugh! Sigh!"

My sister shook her head as if she was trying to pull my hand away, but it didn't have as much strength as I thought.

Even when my sister's nails dug into my arms, it didn't even hurt, as if I was numb.

It seems like a lie.

She was such a weak woman.

That older sister.

My older sister struggling weakly in my arms.

But it was a meaningless struggle.

I conquered my sister. My sister gave in to me.

It was the moment when my relationship with my sister turned around.

"Sister, sister."

I whisper in my sister's ear and move my waist like a crazy person.

All my worries and consideration for my sister were gone.

I pressed my sister down and stabbed my cock with the force of destroying her uterus.

There is no longer a shred of reason left in me.

"Huh, yes, huh… … !"

Poke, pull out. Poke, pull out.

My drill penetrates my sister's narrow vagina. How many times, how many times.

The glans shaves the vaginal wall.

It hits the cervix like a battering ram hitting the gate.

My sister seemed to have no strength to resist anymore, so she just shook and moaned weakly as I thrust.

"Ahhh… … ."

I felt like my head was going crazy from the pleasure that went beyond my tolerance limit.

I was a prisoner of pleasure. I just bucked my waist like crazy in pursuit of stronger pleasure.

My sister's buttocks collide with my lower abdomen, making a clanking sound.

The sound of flesh hitting flesh. The sound of water sloshing. My sister's moans. My voice melted in pleasure.

Every sound I heard made me realize the incredible reality that I was having sex with my sister. 

"Sis, sister."

I keeps calling my sister without any meaning.

It felt so good that I felt like I was going crazy. No, maybe I'm already crazy.

I can't believe there is something in the world that feels so good.

This is sex.

There's no way I can endure something like this for long.

In an instant, a feeling of ejaculation came over me.

I wanted to enjoy this time a little more.

If I could, I wanted to enjoy my sister's body like this all night long.

But my durability was already at its limit.

I, who had already been tormented to my heart's content by my older sister's hands and mouth, could not hold back the semen rising to my stomach.

"Sister, I think it's going to cum… … !"

At that moment, the word pregnancy crosses my mind.

But it was no longer a stage where it could be stopped.

Following my instincts, I stuck my dick deep inside my sister and released semen.

I can feel the glans and the uterus touching and crushing.

I sprayed semen directly on my sister's womb.
