GVG-429 Big Sister's Real Sex Education Yukawa Yuzu

Film Introduction

My younger brother, Teru, has become interested in sex after hearing about it from a friend. As a result, Teru shamelessly blurts out "sex, sex" while eating with his family, and even his older sister Yuzu feels awkward. Yuzu tries to teach Teru about her sexual knowledge and gently guides her to ejaculation with his own hands, but on the contrary, it ignites Teru's curiosity.
