Flopped set, evil turn (NL 10)

[Babalatexi]

I can finally play at party again so I wanted to check it out. With such a drawy board I should've raised the flop more (2.20ish) but somehow my math blew. As played, should I bet the turn, that is, any way neither of the villains doesn't have the straight/flush? Bet or hope to fill up? Without the SB in the hand I could just bet 5 and call a push but we have 150bb's which complicates matters. No reads on villains, new to the table.
