House's eyes were glued to the computer screen as he typed. Chase was on call that night, which was kind of like a night shift, but there weren't many patients, which was a nice change. He turned his computer off and looked through his glass walls.

Cameron and Foreman were packing up their stuff in the other room, while Chase was sitting there, not paying attention to what the other two were doing. He had a blue whiteboard marker in his hand and was playing with it.

He was holding the marker in his left hand and was running one of his fingers on his right hand along the top of it. Slowly. Teasingly. It was almost as if he knew House was watching him.

Bastard.

House frowned slightly. He hated how Chase had this much control over him. It was okay though, because at night, House was the one in control. When Chase stuck the marker in his mouth to suck on it or chew on it, House decided that was enough.

He went to the door and flung it open. "Chase," He barked. "What have I told you about touching the whiteboard markers?"

"Not to."

"Exactly." House went over and snatched the marker out of Chase's hands. He then whacked the younger man on the nose with it. "Bad Chase." He scolded, much to the amusement of Foreman.

Once the Immunologist and Neurologist had gone home, and House had apparently done the same. Chase decided to make himself comfortable in House's office, when he notices something on the desk.

It was a normal size paper with writing on it. It was written in blue whiteboard marker, in House's messy scrawl.

'There's a message for you at the Nurses' Station in front of the entrance'

Chase frowned. "What?" He asked the empty room. He went down to the ground floor, and walked up to the Nurses' Station.

"Hi girls. Is there a message for me?"

"Sure, Doctor Chase." The nurse grabbed a scrap or paper. "It says 'There's something waiting for you in the cafeteria'." She scrunched up the paper. "And that's it."

Frowning and thanking the woman absentmindedly, Chase continued along his way to and into the cafeteria. There was no one there, but there was something on one of the tables. It was a tube of lubricant on top of another note.

'Your instructions are on the door of James Wilson's office'

Chase rolled his eyes. He felt like an idiot, but excitement and curiosity was kind of bubbling in his stomach. Only House could make him feel like this.

'Room 202. Don't turn on the Light. Put the Lube on the table and lie on the bed, on your stomach'

It was dark in room 202, but there was still just enough light to see what he was doing. Almost as soon as he lay down someone appeared beside the bed. The tall man used the restraints on the hospital bed to do what they were made for. Restraining.

House grabbed the Lubricant and straddled Chase, who could feel that his boss was only wearing silk boxers.

"I told you before." He rubbed lube on a blue whiteboard marker. "Never touch my markers."

The next day, Chase chose to stand instead of sit while they were throwing out suggestions for how to pass the time. He had a good reason why he couldn't sit down too; It hurt.

Since they had nothing to do, they were making a list of what they could do on the whiteboard. Cameron was writing it down. She paused for a second.

"Where's the lid for this marker?"

Chase's eyes widened and shifted. House tried, and succeeded, to keep a straight face... He would have to look for it later that night.
