The soft hum of the phone against their ears, the distant voice of a stranger sharing intimate thoughts, sets these Japanese coeds ablaze. Their fingers dance over their slick folds, circling, pressing, as they listen to the other end of the line. The room fills with the scent of their arousal, the sound of their heavy breathing, and the quiet, rhythmic slapping of skin on skin, as they push themselves closer to the edge, their bodies tensing, their voices catching, in shared, wordless ecstasy.
