Saw her naked

So just posted my first confession one redditor said post this experience too..

So at first I have done this long time ago when I returned home from school and walking by my $!$ room u saw her used cloths and heard noise in the washroom, went on out of curiosity/horniness, i saw her bathing through a small gap of the door ( in which we put the key to lock it) u saw naked , and this thing continued with my stepmum too !!

I do know its wrong but I don't know why I did this . Feel guilt abt it Do share your opinion
