Heirloomed porn...
Just imagine your father laying on his death bed. With his last words, he graps a pile of old dusty porn maganizes from 50s/60s/70s and hands them to you. Some of the pages are missing and some have stuck together. As he fights to draw breath, he says: "My son, I will leave you my heritage as I pass from this world. Take good care of them."
A bit later, you're in the toilet masturbating furiosly to your dads porn.
