Oh, these white-skinned girls, they do not need anything but to take a big phallus of a Negro in themselves and, if possible, to swallow even more, to make them shiver and want to vomit.

And why would the grandfather resist? When else would he have such an opportunity. Besides, it's always easier with a temperamental woman - she gets herself turned on and therefore comes much faster.

I've been in the middle of one of those, you can't wish it on the enemy.
What a disgusting man!
