3/6: 44 with overs, bet to protect?

[WotaWaster]

Both Villains seem to be of the 50/10 loose passive donk variety but it is early days at the table yet so no real reads. Interested in also how you would play against 2 total unknowns.
Flop play correct and do we bet turn when checked to?

I am getting 9:1 on flop call.
I think the possibility I am good coupled withthe implied odds of hitting a 4 justifies a call (maybe I am wrong though).
I normally wouldn't be the turn unimproved but I think maybe I should be since it seems unlikely I am beat.
