5/10 fantasticness

[Terrabon98]

Playing 5/10, and the SB and UTG+1 are pretty loose/aggressive/stupid. Anyway, I have 95o in the BB, UTG and UTG+1 limp, SB completes, I check...flop comes 9 5 2 all diamonds. SB bets out, I raise, UTG cold calls, and UTG+1 3-bets, we all call. Turn brings Ace of diamonds, SB checks, I check like a weakling, and UTG+1 bets, SB check-raises, is this an easy fold?
