Hrnyoleperv303's heart races as he steps into the open, riverbank in hand, jacking off for the world to see. The water's rush and the sun's warmth on his skin heighten his senses. He takes his time, teasing his cock, enjoying the taboo of it all. His exhibitionist urges grow, and he strokes faster, harder, until his body convulses, and he paints the riverbank with his hot, sticky cum.
