Get porn without being caught?

So annoyingly any website that’s classed as 18+ is completely locked down (like not even password protected) and alerts my dad. I really wanna watch some porn is there anywhere I can find it without being caught? Like movies or on an app? Anything pleaseeee even audio porn will do

Update: girls I am 18 (almost 19) which is why this annoys me. but I’m still in school and no way of moving out
