The hidden recipient's heart races as they stroke and tease, feeling the stranger's excitement build. They can't resist taking it in their mouth, tasting the pre-cum, and sucking it deep. The cock twitches, and the action intensifies, the unknown participant fucking their mouth with urgent thrusts. The pace quickens, and with a final, deep thrust, the cock releases, filling the eager mouth with a generous load of stranger's cum.
