Jim arrived unannounced to find Spock, naked, braced over a figure in his bed.
"Oh! Shit!" He caught a fleeting glimpse of brown hair disappearing under the sheet before turning away. "Sorry miss!"
The very strained silence was broken only by sheets rustling. Then footsteps pattered fast and the bathroom door slid shut.
"Captain."
Kirk glanced back to see Spock sat wrapped in his sheet.
"Err… staff meeting's now 0830."
Spock nodded an acknowledgement and Jim fled.
"You can come out now."
The bathroom door opened revealing McCoy wrapped in a towel.
"We damn near did that already," he drawled.
