My sister has inverted nipples – hides her nipples and doesn’t hide her nakedness –

[My sister with big boobs isn’t wearing a bra, but her pouch isn’t showing! ? ! ? ]

My younger sister was very plump and her breasts had grown very large.
However, despite growing so large,
It doesn’t look like my sister is wearing a bra.
No bra.
Yes, my sister is not wearing a bra.
As a result, my sister’s breasts sway from side to side as she walks.
And my line of sight also sways along with that sway.
“Brother? What’s wrong?”
“N-no… it’s nothing.”
Since she was swaying that much, it was confirmed that she was wearing no bra.
There are no bulges that would appear if I wasn’t wearing a bra.
What on earth is going on…

As I was thinking about this, my sister asked me for advice.
“Onii-chan… I have something to ask… There’s something wrong with my breasts…”
When my sister said that, she showed me her breasts.
“Brother… there’s something wrong with my breasts…”
The breasts that my sister showed me were certainly strange.
My sister’s nipples were buried inside. Yes, inverted nipples.
“My nipples are buried and won’t come out…Can’t you do something about it, brother?”
“That’s right… I’ll try poking it anyway… If it hurts, let me know.”
“Yeah, I understand.”
I sat my sister down on the bed and placed my index finger on the area where her nipples were buried.
Then, I slowly pushed it in.
“Hmm”
Then, my sister let out a sweet voice.
“Okay, I understand! Leave it to your brother!
First, pinch your brother’s penis between your breasts! ”
“I-I understand! If that helps.”
With that, my sister lifted her breasts and squeezed my dick between them.
My sister’s breasts were extremely soft and my dick became fully erect in an instant.
“Okay! Is this okay?”
“Oh, just move it up and down.”
“Uh, yeah.”
My sister jerked my dick with awkward movements.
However, my sister’s breasts are so soft that they feel so good.
I feel like I’m going to cum soon.
But it would be a waste if I cum here, so I hold back.
“Okay! Next, lie down and spread your legs!”
“Uh, yeah.”
The moment my sister lay down, I inserted my dick into her pussy.
“Ah”
My sister seemed surprised by the sudden pleasure and let out a loud voice.
However, I continued to shake my hips without worrying.
Pan! Pan! The sound echoed throughout the room.
“Oh, big brother! No! I’m cumming!”
“I’m at my limit too! I’m going to cum inside you!” I cum inside my sister.
Dopudpew! !
“Ah, it’s coming out.”
After that, I ejaculated over and over again on my sister’s body.
I squirted my semen all over my sister’s body.
“Already big brother! If you cum inside me like this, you’ll get pregnant!
And ejaculate so much! Big brother’s sex! ”
Even though I was complaining, my sister seemed to really feel the same way.
As proof of this, my sister’s nipples were erect and her inverted nipples were healing.
“No, no…look.”
I said that and grabbed my sister’s erect breast.
“Ah! Big brother! Your nipples are healing!”
My younger sister’s erect nipples were sunken until now.
It had gotten so big I couldn’t believe it.
“Yay!”
“Good.”
“Thank you, brother!”
