The last time one of them had been naked in Jack's office it had been Daniel dropping in from a higher plane of existence where apparently, clothing was a foreign concept.
Jack had no such excuse. Then again, he'd been unbearably horny all day watching Daniel strut around in that fucking suit, playing diplomat to a host of off-world dignitaries. Perhaps that was excuse enough for getting naked?
Being the General had it's perks, and this was definitely one of them.
