Plutonium

o I just got home today and my new laptop charger had arrived! I couldn't find my laptop though. I went downstairs to watch TV untill my parents came home on the Wii U Netflix... but the Wii U isn't there! I called my mom but she didn't answer. About a few weeks ago I watched porn on the Gamepad, but then I left the page, went to settings, cleared cookies, and then cleared Save Data.
Im freaking out that my parents found out I watched porn! Can my parents find out I watched porn on the Wii U?? (Im on my dads laptop, and my parents are coming home in 30 min!)
