He couldn't believe what he was about to do, he had never done something so unprofessional in the whole time that he had worked for Kingsman. He had done similar things outside of his work, but never at work. It was all Roxy's fault, devious little witch that she was, he wouldn't be doing this if it wasn't for her challenge. He looked around the barracks, none of the recruits had noticed him yet, too engrossed in the tales that Roxy and Eggsy were telling. Roxy had seen him, she had smirked at him, letting him know that she knew what he was up to, but she didn't draw any attention to him.
The two way mirror was completely clear, practically a viewing window into the observation room. If any of the recruits or even Eggsy were to look over they would see him. It was an exciting thought. He had forgotten what it was like, the thrill that accompanied the thought of exposure, he'd missed it. It had been quite some time since he had the opportunity to indulge in something like this. Harry almost catching him had been the closest he'd been to exhibitionism in years. He was going to enjoy this, he would take his time and draw the whole experience out as long as he could.
He could feel Roxy's eyes on him, egging him on, he wondered if she thought that he was unwilling to go through with it. He was more than willing though, he craved it; he wanted to feel her eyes on him like they had been in the early hours of that morning. More importantly he wanted the recruits and Eggsy to be unknowing witnesses to the game that he and Roxy were playing.
Merlin met Roxy's eyes, staring at her as he started to run his hand over the front of his trousers, teasing himself through the fabric. He watched as Roxy licked her lips once then turned away, speaking once more to the recruits. He listened to the conversation as he continued to slowly tease himself. Roxy skilfully managed to steer the conversation and soon Merlin was stuck listening in on Roxy and Eggsy retelling old seduction missions.
Merlin freed himself from his fabric prison, unzipping his trousers and taking himself in hand. Other than his cock in his hand he still looked the picture of put together. He refused to shirk any clothing, that wasn't what this was about. It was about not getting caught in the act, being naked was an optional extra; one he wouldn't indulge in at work.
Merlin began to stroke himself, watching the people in the room in front of him; other than Roxy they had no idea. He alternated between long languid strokes and short fast tugs of his shaft. Roxy was watching him again as Eggsy imparted his wisdom to the recruits about posh birds liking a bit of rough. He wouldn't have been surprised if he had followed up with the story of his encounter with Princess Tilde, he didn't though; Harry probably spoke to him about it not being gentlemanly to do so.
Merlin continued to stroke himself, grateful that he hadn't been caught yet. While getting caught could be interesting and pleasurable, it would mean that Roxy won. He wouldn't object to her winning control in the bedroom at any other point, but he wanted to control their first time together. He liked the hungry look that he saw in Roxy's eyes as she watched him, he wanted to see that look more often. It was obvious to him that she wanted to touch herself, but couldn't while she was the focus of so much attention. He smirked at her, letting her know that he was aware of her predicament. When she glared at him he recoiled a little, knowing that he was about to regret his smugness.
Roxy spoke to the room at large, taunting the group of male recruits; detailing the way in which a woman wants to be touched. Merlin began to speed up his strokes as her words paired with the image of her stretched out next to him that morning, touching herself in the way she was describing to the room. He could feel himself approaching climax as she continued to speak. He watched the reactions of the recruits as she finished talking then stood. She brushed off her trousers and spoke again.
"I'm frustrated now. I need either a gun or a bed. Are you coming?"
Merlin knew that her words were meant for him, even though she directed them to Eggsy. He came silently into his hand and continued to stroke himself to sensitivity.
"The range?" Eggsy asked.
Roxy nodded and they left the barracks, the recruits staring after them. Merlin took a moment to collect himself before pressing a switch and returning the mirror to its previous state. Leaving the observation room once he was presentable he headed for his office. Once there he brought up the footage for the firing range in case Roxy decided to give him a show.
