Super tough AK hand against 2 villains (1 super donk)

[PleasureGuy69]

not too many hands on the super donk, but over 15 or 20 hands, he's 79/24/9. The other guy in the hand is 41/11/2.6 so not good either.

What's the plan here on the turn, bet fold? So I bet on the turn, and donk just calls. On the river I'm getting 3:1 but the flush hit so can I still call?
