2/5 B&M Flopped a set on very loose table

[PhatPots]

The table I am playing at is has about 6 loose players, who play 60% of their hands, any ace, 69o, etc. Very pass, they don't raise preflop with QQ or AK

I realized I should have probably raised the BB right away and for anyone making a flush draw make them have to pay? But I got greedy, I think. I was hoping that someone would raise the BB and I would 3 bet.

BB checks, Hero checks, MP1 checks, Button Checks

This confuses me, because I think the BB might have been going for a check raise because he seemed to be one of the tighter players. Should I have bet here?

I thought I was probably beat here, but I had to call one bet because the pot had gotten pretty big, I thought she might have two pair or something.

How bad was my call on the end?
