A curious Japanese schoolgirl, eager to learn about her own body, retreats to her room after dark. With the house quiet, she tentatively begins to touch herself, guided by whispered rumors and stolen glimpses of adult magazines. Her fingers, clumsy at first, soon find their rhythm, tracing the folds of her virgin pussy, gasping at the unexpected pleasure. Her body responds, her breath coming in short pants, her hips grinding against her hand as she chases the elusive orgasm, her innocent face a picture of carnal discovery.
