SNOS-200 My best friend's younger sister, younger than me but very tall, always looks down at me and deliberately lets me see her underwear! If she shows me this kind of thing... I just can't stop! Shirakami Sakika - Shirakami Sakika

Saki is my best friend's younger sister; we've known each other since childhood. But today, seeing Saki again after so long, she's no longer the Saki I knew. She seems to have grown a lot taller, now taller than me, and she's started wearing knee-length skirts. With the slightest movement, I felt my underwear was about to show… Wow, I think I just saw it… light blue striped underwear. I saw it again! Oh my god…
