AK. what would you do?

[rogue8]

30/60 im +1 from the hijack and raise with AKo. SB 3bets right away(loose player but rarely 3bets, expecially in early position) early limper (tag) calls. i call.
flop 2A2 rainbow. SB bets, limper makes it 2. its obvious limper(i know him) has a weaker Ace but prob not Axs. hes tighter. this is where i shoulda 3bet.see what SB does. but i think that would be obvious i have AK. so i just call waiting for the turn. SB makes it 3!. call, call. turn is ugly Q. SB bets out right away. limper calls.. now this is tougher. im not worried about limper at all hes far behind. but SB is being uncharacteristly aggressive. im not beating anything but AJ. would he 3bet out of the SB with AJ? never seen him be aggressive in early like this so im thinking not. AQ now has me killed. AK is chopping. i call keeping limper in.(this turn play is questionable i called flop planning to raise here)
river bricks SB leads out again limper calls. i stop and think about value raising here. but again i raise, SB reraises maybe AQ. AK chops with me, limper gets out. im either raising to chop or lose a bet in my mind so i just call. thoughts?
