My Adopted Family

"Older Sister, what?"

 

My sister slowly started moving her waist.

 

Climb on top of me.

 

My sister's butt rubs my lower abdomen.

 

Round and round, round and round. My sister's soft and elastic flesh rubs against mine.

 

Partly because we were both wearing thin clothes, the feeling felt very blatant.

 

"Sister, stop."

 

"What?"

 

I was embarrassed and tried to stop her, but my sister just played it off.

 

"Can you stop moving?"

 

"Hm, why?'

 

"Because you are butt is touching my stomach…"

 

My older sister smiled brightly at my hesitant words.

 

"If you don't want my butt touch your stomach, should we do it this way?"

 

"Oh."

 

My sister slid down my stomach. Then, this time, I felt my sister's touch in a more sensitive place.

 

My sister sits on my dick.

 

My sister, who was wearing no panties, was practically wearing nothing underneath and her nighty sliding up, letting her bare pussy touch my dick.

 

The only thing standing between me and my sister now was the underwear and pajamas I was wearing.

 

Startled, I twisted my body to somehow escape.

 

Then, my sister grabbed both of my hands and pressed me to the bed.

 

"This is a punishment. Punishment for not keeping a promise."

 

"I kept my promise, right?"

 

Also, is this really punishment? To be honest, it's amazing pleasure. The only downside might be I'm embarrassed.

 

My sister's face looked slightly red as she looked up from below.

 

If you're embarrassed, you can stop. I'm also embarrassed here.

 

"No. I told you to say to me before you masturbate, but you didn't say anything the first time you masturbated, right?"

 

"Well, that's because your weren't home…."

 

"You can talk even if I'm not at home, right? Either by phone or chat."

 

There was some truth to what my sister said.

 

"And I can't forgive you for trying to pretend like nothing happened. I need to punish you so you can never do this to your sister again."

 

Older sister, this is not punishment but a reward for me...

 

"I'm sorry, Sister. I won't do that in the future. So stop it." 

 

Still, I don't like being dominated by a girl. I need to get out of this position.

 

"Why? It's not like I'm hitting you, so what's the problem?"

 

Really, I tried to get away, but it seemed I was weaker than my older sister. My self-esteem got hurt by understanding the difference between her strength and me.

 

My older sister looked down at me, unable to move, and smiled mischievously.

 

"Rye, Why did this get bigger? You said you did it twice today, do you think you still have energy left?"

 

I know what my sister is pointing to without having to say it.

 

I tried my best to hold back, but the stimulation my older sister gave me eventually caused my dick to become erect.

 

"That's sister..."

 

"Are you going to blame it on your sister for this erection? Your a really bad kid."

 

"Oh."

 

My older sister pressed my waist. My sister's soft skin overlapped my erect cock.

 

Judging by the body position, it was clearly my sister's pussy.

 

My cock and my sister's pussy were touching across a piece of cloth.

 

"Whoa… … ♡"

 

My sister's sweet breath passes through my nose.

 

I was nervous.

 

I had a strong feeling that I was doing something I shouldn't have done.

My hands were sweating so much, and so was my sister as we were getting wet.

 

She just moved her waist with hazy eyes, like a drunk person.

 

Back, forward

 

Back, forward.

 

Every time my sister moves her waist, her soft flesh rubs my cock. I couldn't escape the pleasure my sister gave me.

 

"Ah… ♡"

 

My older sister smiled happily as she saw me unable to move.

 

For now, I think I have no choice but to wait until my sister changes her mind.

 

If I don't react at all, my sister will get tired of it quickly.

 

Thinking that, I turned my head away from my sister and pretended not to feel anything. Because I don't want cum just because my sister rubs her pussy over my cock, and cum in my pants. That would be uncomfortable.

 

But still, my sister did not quit.

 

Rather, since I didn't resist, my sister started teasing my waist as she pleased.

 

The speed of movement also slightly accelerated or slowed down.

 

As the stimulation continued, my dick got bigger and bigger.

 

Even though I had already ejaculated twice today, I felt hard, as if this was my first time.

 

"Ha, ha, ha... … ♡"

 

My sister's breathing gradually becomes louder.

 

Even if she is an athlete, it must be difficult to keep moving your back; if you feel out of breath, I really wish you would stop.

 

It's not a good idea to waste your stamina on something like this.

 

My sister said she has a competition scheduled tomorrow as well, and if things continue like this, I might actually ejaculate with my pants on.

 

I wanted to avoid such a situation at all costs.

 

"Tsk… … !♡"

 

And at some point, my sister stopped moving.

 

My sister's hand held mine with such force that it hurt.

 

"Sister… … ?"

 

I wonder if something is wrong. I think my sister will be fine because she has a flexible body, but she may have hurt her back.

 

But my sister had her head down, so I couldn't tell her expression.

 

"Sister, are you okay?"

 

"Whoa… … ♡"

 

Instead of responding to my words of concern, my sister sighed deeply.

Warm breath tickles my hair.

 

"Rye, this is enough for you today, don't masturbation without telling me."

 

"Oh, yes."

 

My sister said that with a tired face. There was a little sweat on her forehead.

 

"You know, you'll get really scolded if you do it again next time. okay?"

 

"huh, I won't do that again."

 

I answered quickly to get out of this situation.

 

It felt like I was going to ejaculate at any moment if I was pressed down by my older sister like this.

 

My sister unwrapped her hands and came down from above me.

 

I had such a subtle feeling that I was fortunate or disappointed.

 

"Sister, then I'll go. Sleep well, sister."

 

Finally free, I left my sister's room.

 

My older sister smiled slightly when she saw me like that.

 

The pajama pants I was wearing that day were wet.
