Lusting after the client and his tie is a really bad idea. Acting on it would be even worse. Which doesn't stop Alex's impulsive suggestion when he realizes that Robin's as intrigued as he is awkward. They're both grown-ups, they can handle the conflict of interest, and if nothing else it will get the awkwardness out of the way. And there's a cheap hotel at the end of their bus route.
Just one date. One night for Alex to enjoy watching beautiful hands managing a tie with style. One night for Robin with a man who can understand his own grooming kink, even if it's not quite the same as Alex's. One night, and then just good friends, while they're working together. Nobody else's business.
But Robin has entirely too much experience with romance at work, and the past isn't staying past.
