Characters: Light, L
Genre: Humor, (horror? XD)
Light was having a pretty good day. Birds were singing, the sky was blue, and he still had no idea that he was going to be handcuffed to L someday. Whistling (but only internally, because Light Yagami certainly didn't whistle), he was moving through the hallways, still getting used to the layout of the investigation tower, when he heard a shuffling from one of the rooms.
Curious, he opened the door… only to discover L masturbating furiously with one hand, the other hand supporting a dog-eared copy of The Hound of the Baskervilles.
Light choked and backed out of the room. Somehow, the very-observant (and apparently very preoccupied) world's greatest detective did not notice this, and Light hurried away to leave him alone with his novel about London's.
L missed this entirely.
As Light hurried away, he could hear very clearly from the room, "Oh, yes! Deduce!"
He hurried faster.
