TOS (Takes place during TWOK): Kirk/Spock; Rated PG; drabble
"Excuse me, Captain, but did you just look at the janitor's rear?"
"Huh?" Kirk stopped in the middle of the corridor; Spock had taken him off guard.
"The janitor we just passed. You turned your head to stare at his ass."
"Yes, you did."
"Are you jealous, Spock?"
"Jealousy is an emotion, Captain, that would be illogical for me to indulge in." The smirk playing about the corners of his lips belied his words.
