QQ on WPX

[MD_]

I'm playing a 2/4 game on WPX.
The BB is a player I see all the time on WPX, and he's never out of line that I can see.
His name is Satyre (or something like that, I don't remember the exact spelling).

I'm UTG with QQ and raise.
Button calls. BB calls.
Flop : K52 rainbow
check, I bet, button folds, BB calls. (standard play)
HU on the turn:
K52 (5)
BB bets into me. Now what?
I called.
River: K525 (2).
BB bets. Now What?

Thanks for your help.
