I'll give a go at guessing your reasoning. button is more likely to have called your raise with a drawing hand than high cards. so on the flop there's a good chance he's betting a draw, maybe he can take it down and maybe he gets a free ride to the river if he gets called. you realize this and bet the turn to punish him. if you were heads up it could almost be a value bet with king high (!!).

the fly in the ointment is the BB, what does he have? very hard to put him on a hand playing this way, it's hard to put him on a draw with a flop check call, so I lean towards a made hand of some kind, probably pretty good but not great. would he play AK this way? it's possible I guess. I can't come up with a hand that would play the flop and turn this way.
