An unrefined expression, white skin, a secret part that no one has stepped into.A girl who is completely innocent.Her name is Honami Uehara.To put her personality in simple terms, she is naive.She is a hard worker and hates to lose.Her first time naked, her first penis, her first feeling, her first penetration.The reason why she dedicated her first time, and the meaning of her tears... I had sex for the first time with an amateur man who was awkward. It will be the first complete documentary work in S1.
