JJ out of position with K high flop

[juggler97531]

I have history with Villian - before this hand i stacked him couple of times and he can be tilting against me. He is about 40/15/1 donkastic, very rude and offensive chat.

I was feeling kinda lost in this hand. I think i should have cbet.
When i missed the flop bet however the rest of the hand seems natural. River is bet/fold... or is it?

Comments on all hand plz.
