Sherlock had never been shy about what he wore (or didn't wear) around the house, but John had always been totally dressed.

Until this morning.

And either he was too tired to realize that he only had his pants on, or he just didn't care, the latter of which only confused Sherlock more.

"Yes, please." He finally stammered out, trying as hard as he could to keep looking at his microscope and not his almost unclothed flatmate.

Of course Sherlock noticed the tiny grimace. "John, are you feeling alright? Did you take your medications this morning?"
