The donkbet trifecta - AKA WTF am I doing?

[7ontheline]

After playing this hand I realized that I didn't really think things through very much while I was playing it. More importantly, I donk-betted all 3 streets! Anyway. . .

I don't have a ton of hands on either of these guys. They played pretty much like you would expect them too given their PT stats. UTG is a sLAG preflop but more passive postflop (34/20/1.15). He goes to showdown a lot. MP is more classic LAGy, aggressive after the flop also (54/23/2.4). He also doesn't like to fold and will try to slowplay his bigger hands.

I'm most interested in comments on the flop and turn. I bet the flop expecting to get raised, planning the get some more money in on the turn. When the 3rd club hit, I bet out to try to prevent any clubs from getting any free cards. Should I have 3-bet the flop? Played the turn differently?
