Two innocent-looking Japanese teens, sheltered and curious, find themselves alone in a quiet classroom after school. Their eyes meet, and a spark ignites as they notice each other's budding desires. One girl, a sweet, petite thing with rosy cheeks, tentatively reaches out to touch the other's thigh. The second girl, a bit more daring, takes her hand and guides it upward, revealing her excitement. They share their first tentative kisses, exploring each other's young, untouched bodies with eager inexperience.
