The booth door locks, sealing in the illicit act. A stranger's cock, hard and ready, slides into the waiting, hungry mouth. Tongue swirls around the tip, tasting pre-cum, before taking the length deep, gagging slightly. The unknown lover grunts, their pace increasing, balls slapping against the chin. Fingers grasp the base, jerking in rhythm, feeling the pulse of impending orgasm. Cum floods the mouth, dripping down the chin, a secret shared between two anonymous bodies.
