Straight on a paired/flush board (lc)

[holdin2]

Villian 46/18/.6
Was this OK? The paired board 3-bet along with the flush completing on the turn made it harder for me to put more money in. Looking back now, the flush doesn't seem very likely given the action anyway. Should I have thrown something out there on the river?

Make it 14 on the river. Alot of worse hands will call you here.
