Villain is 74/7 and is very passive.

When he checks flop it seems weak and there are flush draws and maybe Kings that call me.
When he checks again on the turn I don't think he has improved I think he would have let me know if he had a straight there as he was a straight forward passive player and I think KQ maybe bets out here not too sure? He could easily just be calling with a flush draw and maybe a pair on the flop so is it right that a bet again? if so what sizing is right?
