On the first day he watches from his desk as she chews her lip.
On the second, he imagines kissing her and tracing his fingertips slowly along her jaw.
On the third day he leaves early, picking up his girlfriend on the way to dinner with his parents.
On the fourth day he thinks about taking her to the bathroom, grabbing her hair in his fist and fucking her from behind.
On the fifth day he masturbates in a cubicle, waiting for the footsteps to pass before he comes.
On the weekend he sends an email asking to change departments.
