Do u know this manga?

Basically, I read it two yrs ago, but I just can't forget it for some reason. It's a yaoi, where a coworker is masturbating on his boss's desk 'cause he likes him, and then another coworker enters the room. I think they have a weird sort of blackmail situation. Pls help, so I can actually sleep at 3am.(≧∀≦)
