DragonHorse10
Takes place after the first season, but happens before season two. Lucifer finds himself feeling weird every time he is near Alastor, his face flushes, he gets hot, and he gets odd tingles in his stomach. At first he thinks he must be coming down with something, but as time passes will he figure out what is making him feel this way?
