Under the soft glow of lanterns, two Japanese schoolgirls, clad in their crisp sailor uniforms, sneak into an empty classroom after hours. Their hearts race as they lock the door behind them, their hands tentatively reaching down to lift their skirts, revealing their lace-trimmed panties. They lean back in their chairs, eyes locked onto each other as they slowly slip their fingers beneath the fabric, their breaths hitching as they touch themselves for the first time, their moans filling the silent room with a symphony of forbidden pleasure.
