Anonymous Confessions Part 2

Confession

ever since i was little i've always kept my sisters dirtiest sexual secrets. Now that i'm 15 my sister is married and changed into someone else, as she betrayed me to my parents many times before, i know that if my sister somehow learns that i'm secretly dating someone, without my parents knowing, she'll bust me with no hesitation. So every night i dream of ruining her married life by spilling her secrets to her husband and my parents, just to take revenge for all those times she betrayed me. But despite everything, I still feel like i shouldn't do it
