Jean-Pierre is cleaning the hangar, alone... or so he thinks. Jacket open, hand in overalls, he indulges in a quiet, well-deserved wank. Suddenly, Lewis Quintini, the manager, emerges in the doorway. He opens his mouth... but Jean-Pierre, his eyes resolute, cuts him off with a gesture. In two seconds, the roles are reversed: Jean-Pierre pins Lewis up against a locker, pulls down his pants and, without a word, begins to work on him: fingers first, then a full fist, slow, deep, implacable. Matthieu Paris (Jean-Pierre) leads the way, and Lewis Quintini becomes the most diligent man in the hangar. A stunning lesson in power: the surface technician becomes absolute master, and the manager ends up dilated and fulfilled!
