TPTK 10/20 ShortStack is [censored] up my MOJO

[JacKnight21]

5/10 Wynn 7 handed
Hero CO 3k+
VillainA EP 3k loose passive perfect
VillainB Button $480 loose pf but has always had a hand postflop

PF-VillainA limps I make it 50 w/ AKcc both Call
Pot-$165-Flop Ks9d4s VillainA checks I bet $120 both call
Pot-$525-Turn 6s/completing flush VillainA checks--I??

I don't like this spot and it seems to come up so often. vs Villain A this is an easy bet but Villain B will only call/raise with better.
