K4s postflop squeeze

[Wu36]

SB has been calling in the blinds and donking into me constantly. BB is 17/13/2 and on 3 of my tables, hes playing 6 total (as am i). I was running bad at this table, but in control of the other 2.

SB's donking range is huge, I'm not too concerned with him. BB's range should be wide here but hes tight so it might still be sets or 45. I think he folds 44,55 77-JJ here, and I don't think he felts if he somehow managed to have the nfd (I can't see him having A2 or A5s here, maybe AJs). I'm a 2-1 dog if he has a set or straight.
