Hidden in the bustling crowd, the voyeur listens intently, his cock hardening as he hears the wet, squelching sounds of fucking. The desperate girlfriend's moans, muffled yet clear through the audio, guide him like a beacon. He finds them, her dress bunched up around her waist, him pistoning into her needy pussy. She's lost in her pleasure, her eyes closed, unaware of the audience. The voyeur's hand moves to his cock, stroking in time with the couple's rhythm. As her orgasm approaches, her cries become louder, more insistent, pushing him closer to the edge. They come together, his cum pulsing out as her pussy clenches around her lover's cock.
