my 8 year old brother saw the yaoi on my phone

please kill meee what do i do?? what if he tells my parents?? yeah i'm definitely gonna die if he does. it took me months to get rid of my paranoid habit of deleting my history every day and being scared of showing my phone to anyone. ughh am i making a big deal about it? my little brother sort of understands what it is and he said it was disgusting. just give me the death penalty already. am i a bad sister??? i only lent him my phone since he was nagging me about using the laptop when i had to do schoolwork. just please end me.
