SNOS-327 | I want to jump in and catch a glimpse of my innocent little sister's panties. My New Year's Eve and New Year's Day with my cute stepsister - Hatsumi Nanoka

This New Year's holiday will be just me and my sister-in-law.
Even though she's my sister-in-law, we've been living together for many years now.

When it's just the two of us, she asks me to help her study for an important exam...

But...well...no...how should I put it...
Well...if I say something like that...as an older brother...I'll lose my...dignity...
No, Nanoka is really cute...
Eventually...she might bring a boyfriend home...well...when that happens I'll be a proper older brother...welcoming him...yeah...
That's what I should be doing...but...after all...it's just my male instincts...my friends seem to be interested in Nanoka too...
I mean...please don't leave me alone with Nanoka...I can't take it anymore...Sorry Nanoka, I'm not your older brother, I'm a man

Panties visible between her thighs!!!!

The excited brother-in-law's sudden panty flash rampage.

Innocent Nanoka can't hide her confusion.

What happened to her older brother who was supposed to be kind...

An unconscious panty shot peeking out from deep within her skirt
A panty shot that peeks out from below when she stretches up a little
A panty shot that appears from between her legs when she boldly spreads them open during a game
A panty shot seen through the slightly open gap of the sleeping beautiful girl
A colorful panty shot that can be seen from under her skirt when she sits down and opens it

Nanoka's panty shot that can be seen from any angle

An innocent Nanoka and her troubled older brother's confused andドキドキ (heart-pounding) sex that begins with panties

It's all the panty shot's fault...or so it seems.
