Under the watchful eyes of Parisian pigeons, a Marine and a Frenchman, both inexperienced with men, explore their desires in broad daylight. The Marine, assertive and hung, corners the Frenchman against a wall, their stiff cocks pressing against each other through thin fabric. He takes out his throbbing, veined dick, slapping it against the Frenchman's face. The Frenchman, nervous but excited, opens his mouth, allowing the Marine to push inside, gagging him on its length. The Marine, grunting, holds the Frenchman's head steady, fucking his mouth roughly, the sound of their pleasure echoing in the narrow alley.
