Reraised KK OOP on a monotone flop 5/10

[9cao]

5 handed. The 2 Villains are regulars but wouldn't really know my game nor do I know theirs. I have been at table for about 5 minutes. I have 1k and they both cover.

CO raises to $33. Button calls. I raise out of the SB with K [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/spade.gif[/img] to $115. BB folds. CO and Button call.

Flop: pot=$355

What is the plan from here? Bet size? Plan if raised?

I was thinking that a lot of hands have large equity against my hand and I am already behind AA, maybe 66 or 88 from button, and AK (maybe AQ of clubs) but think I am good here a big percentage of the time.
