As for that fic you linked to, if a mother fluffy pony was giving me lip like that, I would bind it to a wall whilst I take one of her children and cut out it's throat in front of her

Same here.

Fucking mother, who the fuck does she think she is? I'd make sure it was crying as I slowly hammer toothpicks into the space under her toenails.

I will stretch her anus until she starts shitting blood in my mouth...and I will let the babies watch it.
