"If you consider signing my paycheck paying for it," Ianto said idly, "then I suppose that could be true." He smiled, shaking his head. If he was completely honest with himself, he knew that wearing jeans to work would mostly be to tempt Jack into not working, but they had a large enough staff now that they could get away with spreading the work around more. Which meant that he was well within his rights to distract Jack from his work one day out of the week. "It's certainly negotiable," he said, innocently. "I do enough the other four days."
"I just don't feel like working in here," Ianto said calmly, "where the others can interrupt. Besides, the archives could use a thorough working over." Or maybe he meant the archivist. Hard to tell. He gave himself a second to compose himself and smoothed his suit, before following Jack down to the archives. He did his best to look calm and professional and not draw attention to himself as he passed the others, and when he reached his destination, he shrugged off his jacket, hanging it on a coat stand that he kept in the archives for when he was working. He calmly unbuttoned and rolled up his sleeves, then removed his tie and stuck it in the pocket of his jacket, leaving the top two buttons of his shirt undone.
Turning back to Jack, he kissed him, running a hand through his hair before pulling away just enough to speak. "If you could get on your knees, Captain," he said, tone utterly professional and almost disinterested in spite of their proximity.
