A curious Korean teen discovers her body's unique response to arousal. As she simply stands, her hips move in rhythm, her pussy lips parting and inviting. She tentatively touches herself, gasping at the wetness, and then watches in amazement as her fingers are drawn inside, her body greedily sucking them in. She experiments, trying different angles, finding that even her thighs can stimulate her clit. Lost in her newfound pleasure, she doesn't notice her reflection in the window until it's too late - her neighbors have been watching her self-pleasure performance.
