Your chastity cage set off the metal detector. The TSA agent quickly figured out you were a kept boy during the required pat down. The little erotic moans you involuntarily let out each time he touched you let him know you were horny and ready to serve him. So you were selected for the “random” enhanced screening. He took you to back and performed a strip search.  

He put you on your knees, naked, and forced you to suck his cock.  Decided he needed a second opinion, before he could allow a suspicious character, like you, board a plane, so he invited several fellow inspectors to use your mouth as well. Looking at your ticket, he told you to do a good job and get his co-workers off quickly, or you would miss your flight and be forced to stay overnight, until the next flight in the morning.
