Part 1 of 2. Hiking on wet rocks is dangerous enough, but Diego and Walter try doing it with boners. Diego reaches into the rushing river and pluck out Walter. Walter rewards him with a kiss and then has his cock in his mouth. After returning the favor, Diego pushes his cock into Walter's ass. Gently at first, he sinks it all the way to the balls and then starts fucking Walter. After fucking him amidst the waves, Diego gulps down Walter's load and then shoots his wad on Walter's eager mouth.
