my daughter gave me her phone

This happened some time ago: my daughter gave me her phone to fix it because it was freezing when booting up. I fixed it and was very curious to peek into her life, so I scrolled through her gallery. But what I found was shocking. A folder full of nude photos, and not just innocent ones. She took pictures of herself undressing, showering, peeing, and even changing her tampon. And lots of material about masturbating with candles, her electric toothbrush, and (!) her mother's sex toys. Then I saw that she had a page on OF, and it turned me on, so I even subscribed.

Since I have a huge inclination toward incest, all of this was and still is too exciting for me. I think it was her intention for me to find it... and I couldn't stop masturbating to it.

What do you think other daughters and parents would say about this? I would appreciate some advice.
