Just plain nastiness

B+M 2-4 game last wednesday. I am sitting at $440, villian has me covered. I look down at 2 red Kings. Raise to $15 in middle position. 2 callers

Flop 9 K 9 (two spades)

Hero checks
Villian bets $20
Hero Calls

Turn: 5 spades

Hero checks
Villian bets $40
Hero Raises to $120
Villian calls

River bricked, 6 I think

Villian goes all in
Hero Calls all in

He is holding 99.

Now this isn't a bad beat story, I wanted to ask everyone if I should of slowed down at any point in this hand? Can you ever put someone on quads? I know in SS doyle says to never be fearful of quads.

Is this just a hand where I have to grab my ankles and take it with a smile?
