VEC-322 Mother's best friend Yuka Shinohara

Kenichi is tired of his mother nagging him to study, so he decides to ask Tomoka, who happened to be visiting his mother, to watch over his studies... - Kenichi is confused by Yuka, who is not only a talented woman who graduated from a national university, but also a beautiful, sexy, and perfect adult woman. - Seeing Kenichi's naive reaction, Yuka teases him, saying, ``Why don't you teach him about girls instead of studying?'' - Kenichi, completely captivated by Yuka's devilish charm, sneaks into the bathroom to peek at Yuka while she is taking a bath.
