Snoop in his sisters' rooms.

John had two younger sisters: Kelly, who was 19 and year behind him in school; and Stephanie, who was 18 and just finishing up her freshman year. They each lived in the two other bedrooms on the second floor apart from their parents' room. John glanced from one door to the other. He could snoop around in one of their rooms while he waited for the shower, maybe find a diary or such. He smiled evilly (though in a good-natured, bastard-older-brother sort of evil) to himself and suck softly on his tounge as he tried to decide.
