Friend downloaded mobile porn on my phone?

Hello Vee Asked: Friend downloaded mobile porn on my phone?

So the title says it all. My friend thought it'd be so hilarious to download porn on my phone.

I have a Metro PCS phone, it's been disconnected for 3 months. My friend downloaded gay porn from some site called xvideos. will they charge me for the porn? I'm so worried because what if they do charge and my parents see the phone bill? I don't know how I'll explain it to them, especially since it's gay porn. I'm just freaking out now. My friend said that he just pressed download and it downloaded, that nothing popped out saying if he wanted to subscribe or whatever.

Please Help?
