Today he's acting even more unusual than always. I quickly found out why. Tonight would be his first real date with a girl. I know he has a doll and he jerks off all the time. Maybe now he won't peek at me in the shower and spill his cum all over the house. I didn't expect him to ask me for help getting ready for a date. It's unacceptable, we're step-brother and step-sister. But I felt sorry for him and he offered all his pocket money for that. I really need that bag.
