Burn it. Stove, lighter, anything - Its what i used to do when i printed all those fake $2500 bills.....
Some people have zero common sense. It's sad really... flush it down the toilet burn it rip it to shreds pocket it, throw it out at a random garbage can outdoors the list is endless...
It's not two guys fucking/sucking porn is it? If that is the case, just leave it on the kitchen table. Quickly gather a few clothes and split. I mean leave the state, maybe the country, change your identity and never disgrace your family like that again.
Tear the papers into pieces, soak them in water, turn it into a soggy ball of paper and wrap it in a plastic bag and sneak it into the garbage when no one is looking.
You're 28, and you're worried about your parents finding out that you look at porn? If I were them, and you were still living with me, I'd be worried if you WEREN'T looking at porn.
Firstly are you really 28? I doubt, but if yes, you should worry less about this issue. Anyways I am presuming with you that you're facing a real problem there, lol, google the web for "Encrypted Magic Folders" software. Install it, follow the instructions, have a master account password that you should never forget, then hide, encrypt, and scramble your porn folder, so no one can even know that it exists but you. For total removal, try clicking the folder, than perssing shift + del, then selecting yes. This always helps.
Unless your parents are like mine who are crazy and sexually inactive (thewy sleep in different beds) they should be understanding, keep the porn man.
You'll want to supplement those armor piercing rounds with some hollow points, or some other expanding ammunition, for some extra punch. This is going to be a big job. And have an air strike on standby.
Just be careful if you burn stuff. You don't want to accidentally burn down the house. You'll be scarred for life!
Erm, after the recent posts, I just noticed that the OP is having a problem with HARD-COPIES of porn, which is a different story. Put them in your pocket, jacket...etc. Go out like you normally do... Garbage bins!!!
