KJo makes Second pair on ugly flop

[Redd]

Bet365 0.50/1 game. Generally loose and passive.

Hero raises KJo from EP, 2 unsurprising CCer immediately behind me, blind blind calls.
Flop comes a healthy KAQ rainbow. Check, Hero bets and all three of them call.
Turn comes 8 of rainbow. Check, Hero...

What's my plan for the hand?

edit: Changed hand because I messed up one CCer.
