Older Sister Gives Brother Hand Job

Mom and dad always go on these trips without us... its so boring staying here! im going swimming... when i come back inside i discover my brother has gone through my phone! he sends bikini photos of me to himself! Since he was in a rush he forgot to delete the evidence he left on my phone. I cant tell mom and dad... and I cant really ground you or anything... this is so fucked up!! what am i supposed to do with you!!
