New at a table, I'd usually only overlimp with A6s in this spot, but here I decided to raise nonethless.

Here on the flop, I decided to draw (as it was only about 1/2 Pot), given most likely 5 clean outs, beeing deep enough, having position and a well disguised hand (so I guess the line is O.K.)

However, I wonder how you usually react to those donk bets in similiar situations?

I like
on flop you may even have the bast hand who knows, on turn [censored] it you can fold
