You and lucifer where playing hide and seek because you got bored. A few rounds in you decide to hide under his desk and after 30 minutes of looking he can't find you and comes to sit at his desk not knowing you were under there and before you had a chance to come out he was already sat down. not knowing how to show yourself you try and avert your eyes from his crotch and stay quiet until he gets up again.

He got a call about work and once he had hung up you could tell he was frustrated.
