KK UTG ( OOP with an A on the Flop )

OK, I had been dealt a fair few good hands, had about an 85% win ratio on my showdown hands so opponents were very weary about playing me.

PokerStars No-Limit Hold'em, $0.02 BB (6 handed) - PokerStars Converter Tool from FlopTurnRiver.com

SB ($2.53)
BB ($2.20)
Hero (UTG) ($6.81)
MP ($0.62)
CO ($2.49)
Button ($4.73)

Preflop: Hero is UTG with K[IMG], K[IMG]
Hero bets $0.06, 1 fold, CO calls $0.06, 2 folds, BB calls $0.04

Flop: ($0.19) 9[IMG], 10[IMG], A[IMG] (3 players)
BB checks, Hero ???

The fact I get 2 calls immediately makes me think one of them, if not both, have at least 1 A or K. How do I proceed with this one?
