Suggested fix (unconfirmed): Stay home instead of going to the city, work on the computer, and choose erotic games so she catches you. Alternatively, do not cover yourself with a towel after getting out of the shower.
The problem
How do I get Accidental Peep Shows? - Bowling - In the park twice - In the locker room - In the pool What did I miss?
What players suggest
Mhh she caught me watching porn and I didn't get it. Tried erotic games as well but didn't get it either, strange.
Suggested fix (unconfirmed): Accumulate enough negative bond points with Lara and follow the specific NTR decision guide for the office and basement scenes. Avoid strict routes with other characters like Angelica that prevent you from gaining the necessary negative points.
Suggested fix (unconfirmed): Turn the music completely off and turn your volume up to 80%. Accept that the game features text-only dialogue without full voice acting.
