You look for something else to distract you.

You sweep your drawings to one side and open up the nurses desk drawers. In a hurry to take your mind off your throbbing cock you delve you hand into the drawer grabbing whatever you see, mostly medical files that are practically incomprehensible to you. As your hand reaches the bottom your fingers curl around something thick and firm. In truth, you know exactly what you're holding, but your arousal encourages you to give in to your curiosity and confirm your suspicions. Your eyes light up as the shiny red dildo emerges from the desk. You hold it close to you, resisting the urge to take it in your mouth. The nurse must use this, perhaps she hadn't washed it. You think back to her taste as your eye up the tip of the rubber dildo.
