My Adopted Family

Suddenly, I grabbed my crotch and rolled around on the floor.

"Ahahaha! Rye! are you okay?"

My sister laughed until she was out of breath and patted my back.

It was like that. 

My older sister enjoys teasing me and playing with me. There have been so many shocking incidents these days that I forgot about them for a while, but my sister has always been like this.

"My leg is torn apart."

"Let's see. Are your legs really torn?"

My sister took off my sweatpants.

I was in a stunned state and couldn't resist in any way.

Naturally, my leg was neither torn nor bleeding.

Only the erect cock was exposed.

"Rye, you're lying about being your legs torn, right?"

"It really hurts… … ."

I said painfully, and on the contrary, my sister smiles even more happily when she sees me like that.

"Really? Well, your sister will pull pain out with her mouth."

"Oh… … Wait a minute, sister, I'm sweaty."

My sister started stroking my erect cock with her hand.

Then she brought her face close to my crotch and sniffed it.

"Rye, it's awful smell."

"So, let me take a shower first…"

"It's okay. I just do it."

Despite the comment that it stinks, her face somehow looked happy.

These days, I wonder if my sister's mysophobia healed or what?

"Oh…"

And without hesitation, my sister took my dick in her mouth.

"Chururup, churup, churup."

And then, as if she had been waiting for this moment, she started sucking intently.

How did it happen again? I was definitely here to exercise with my sister.

My older sister was holding my dick with one hand and moving her head vigorously.

She raised her eyes towards me and watched my reaction.

"Ah… sister… …"

"Chul, Churrup, Churrup♡"

When I made a sound as if I was happy, my sister became happy and increased her sucking speed even more.

The fellatio my sister gave me was not as gentle as the fellatio my mother gave me.

It was a violent act that clearly showed my sister's personality as if she would take it away by force if I did not give her semen.

But that doesn't mean it doesn't feel good.

Rather, it felt good enough to forget the pain.

"Ha…"

That sister is sucking my cock.

If it were me a few months ago, I would never have believed it.

Gratitude and loving feelings for my sister filled my heart.

And without realizing it, I was putting my hand on my sister's head and stroking it.

My heart was pounding for a moment, but my sister was concentrating on sucking my dick and wasn't paying attention.

"Haha."

My sister sucked my cock without even slowing down her pace.

On the contrary, my breathing became increasingly rough as I just sat there quietly.

"Oh, sister, I think I'm going to cum!"

"Chuuuup, chuuup. Chururup♡"

Even though I told her in advance, my sister did not stop fellatio.

Rather, the suction power became stronger, as if telling me to put it out quickly.

"Ahh… … !"

Finally, I ejaculated. In my sister's mouth.

It felt so good that I was completely lost, and my back was shaking.

I squeezed my sphincter in and out, pouring every last drop into my sister's mouth.

"Oof… … ."

"Hhu, sister."

When I came to my senses after ejaculating, my older sister was puffing out her cheeks and making a face.

Tissue. I needed toilet paper. So that my sister can quickly spit out the semen in her mouth.

Otherwise, my life was in danger.
But there was no toilet paper in this room.

Instead, I took a towel that was lying on one side of the room, but before that, my sister took my underwear that I had just removed and spit out the semen in her mouth.

Ah. my underwear. If anyone saw it, they would think I was having a wet dream.

No, it might be better to misunderstand it that way than to find out what actually happened.

I decided to take it positively.

"Ouch."

That was the sound of my sister hitting the back of my head.

"Cum in my mouth one more time and I will kill you."

My sister glared at me with a scary face.

She was happily sucking my dick just now.

"Sorry… But that's you.. ."

I said I was going to cum, but it was you who wouldn't let me go. To be honest, there were some things that were unfair to me.

But there was no way my tyrant sister would listen to my argument.

"Urgh. It's smell. I'll wash up first, so you can either clean the place, or wash up."

"Huh… Okay."

And my sister left the fitness room without even looking back. She probably just went to the bathroom.

I put back on the pants I had taken off and wiped the sweat on the floor with a towel.

Now that I think about it, where did my underwear go? Did my sister take it?

Surely she can't just put it in the laundry bin? Then the semen would get on another laundry, too.

I finished cleaning up the fitness room with a creepy feeling.

The next day, my underwear was cleanly washed and in the laundry bin.
