Check call. If it were heads up you could donk bet a blank turn, but in a three way you should just check call the turn or fold depending on the pot odds.

Incidentally, that king is a terrible card for you. Thats often going to be make a set for someone here based on the info you have given me about the villains involved. thats why I opt for check call, cause if you hit the flush on the turn you can usually get a juicy load of EV in for the river. But check fold isn't terrible here IMO. Check/raise is awful.
