How to permanently ruin and degrade a grandmother

the other night i was getting my granny drunk and stoned,,i had convinced her that i can do tattoos,,within an hour,i trashed both her forearms.she now has my initals in bigletters across her forearms,and 'ftw' on the other.her k**s were humiliated that ive tatted gilf on her knuckles,,next time she pisses me off, she will be forever shamed with slut tatted on her knuckles,and i am laughed at for knocking up a whore old enough to be my mother,,the dumb bitch has told me numerous times that she was black cock property and gangbanged by bikers,,i get excited licking her used fuckhole knowing my tongue is getting leftovers from a used whore,,i love my granny ,but i also enjoy degrading her,,how else do you trear a dumb bitch with more clit than brains,,
