Top pair Top Kicker in huge multiway pot

No reads as I just sat down maybe 10 hands ago. Criticize my play on all streets? After flop I was worried of being up against a set so I slowed down. Should I have raised the turn or river? - The raise would not have been to protect my hand as they all would have called one more bet anyways.
