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 - Is It Hatsumi?

This New Year's holiday, it's just me and my sister-in-law. Even though she's my sister-in-law, we've been living together for many years. When it's just the two of us, she asks me to help her study for an important exam... but I... well... no... how should I put it... well... if I say something like that... as her brother... I'll lose my authority... or something... no, maybe... she's really cute... and one day... she might bring a boyfriend home... well... when that happens...
