Airport Controls...

 ... can be quite a hassle.

 Her security check was worse than most.

 

They observed Clara since she left the airplane, and then stopped her at customs control. She caught their eyes because of her boobs.  But they stopped her because of her atypical behavior.  Usually women with such blatant assets are wearing them proudly, but she acted very awkward, self-conscious and shy.

The agents, who introduced themselves as 'Alias' and 'Anon', immediately made her strip.  Her clothes got bagged and x-rayed.  But her bra was not stuffed with contraband. Only with boobs.

"Aren't these balloons a bit big for a girl of this tiny stature?" Alias mused.  "These things would look ridiculously huge even on you!" her colleague jokingky retorted. "Something's dubious about these udders."

Clara fought to hold still and keep her hands at her sides while both agents shaked and groped her freshly aug-mented, embarrassingly huge udders.  But these balloons felt just like real saline implants.

Only when they finally made x-rays of her chest, the agents believed to have found what they were looking for.  Swimming inside her implants, there were pouches, containing tiny metal cylinders and electronics.

"Thefe are to... to infhlate my breaftf per... per remote conthrol." Clara explained timidly.  But the agents did not believe her.  "Humbug! Such implants don't exist!"

"Not here. Thefe implantf are too exftreme, too... lewd to get approfed in our country. That'f why my Maft... my partner made me fly to a clinic abroad."

 Agent Alias grabbed her keys from the table. "Then this remote surely is not a garage door opener?" She pressed its button. Clara winced "Ouch!  Pleafe don't!" and clutched her boobs with her arms.

"Arms down!" the woman commanded, and Clara immediately obeyed. "Did you see any change?" Alias asked Anon. "No, they're still just huge..."  He chuckled. Then he put his ear onto one of Clara's boobs. "Press it again!"

Clara bit her tongue to not make a sound when her sensitive boobs got stretched even more.  With success!  "I think I heard it." agent Anon stated.

Alias pressed her ear on the other boob, and pressed the button once more.  A low "pfft" could be heard as even more CO2 expanded into her implants.  "I think she's telling the truth." Anon stated, and Alias agreed. "If she wants to have such freaky boobs for her mast-errm... man, who are we to stop her?"

"You need to hurry, Miss!" Agent Anon helped Clara to force the buttons of her trenchcoat to close and handed her back  her purse.  Meanwhile, Alias retrieved the bag with the rest of Clara's clothes from the x-ray scanner.  "Your onward flight already started with boarding!"

And so Clara ran to her gate, hiding her naked, aching and wobbling boobs beneath the dangerously strained buttons of her coat.  She had totally forgotten about the doctor's warnings regarding the further expansion of gas-filled boobs at cabin pressure.
