Ten public strokes, a silent language between strangers, their hands moving in rhythm with their hearts' pounding. A woman in a trench coat, her leg propped on a chair, strokes herself to orgasm in a crowded café, her moans muffled by a book. A man in a car, windows fogged, his hand working his cock, comes undone as a passerby glances inside. A couple, entwined in a crowded alley, their hands exploring each other, reach their climax together, their bodies pressing against the cold brick wall. Ten strokes, a shared secret, a public display of private desire.
