Vint70s-Lvr: Tony Peters cruises Leo Ford on a New York street, and the scene is set up as a locker room encounter. Wearing a football uniform Tony slowly strokes himself to hardness as Leo watches. Leo, wearing a suit, pulls his long dick out of his trousers. While classic 70s TV ads play in the background, Leo and Tony jack. Tony cums in his jockstrap, then Leo follows suit. Part 2 of this scene continues in an apartment, here.
