Q9s flops a good draw

[aargh57]

Button is 44/27/2.8 after 557 hands
SB is 33/12/2 after only 40ish hands

On the flop I raised for value hoping both would just call.
Turn I wasn't sure if I should bet again but I do have a very good draw.
The river donk I'm unsure of. I hardly ever donk and don't know if this was a good time to do it but I would hate having a Lag raise the turn but give up on the river because it's now mw and a scare card fell.

Anyway... Prima 5/10 4 handed
