NPs containing double genitives: "this harassment of her of yours"
I'll simply cite the King of Spain's daughter's doll's dress as evidence that "possession" (whether conveyed using the Saxon genitive 's or the preposition of) can be used recursively to any required depth.

This is the horse and the hound and the horn
That belonged to the farmer sowing his corn
That kept the rooster that crowed in the morn
That woke the judge all shaven and shorn
That married the man all tattered and torn
That kissed the maiden all forlorn
That milked the cow with the crumpled horn
That tossed the dog that worried the cat
That killed the rat that ate the malt
That lay in the house that Jack built.

Obviously the rules of the relevant syntax allow us to produce constructions that are ridiculously ugly and/or difficult to understand. But it's always a stylistic choice how far to take things, not a matter of "grammatical rules" as such.
