Hidden among the greenery, a lonely man finds solace in his own touch. In the quiet of the park, he unzips, his cock springing free. He strokes, feeling the cool air contrast with his heating flesh. The rhythm picks up, his breathing quickens, and he can't help but glance around, the thrill of potential discovery adding to his arousal. His body tenses, and with a final, hard pull, he releases, his cum landing on the grass, a secret only nature knows.
