Top 2 on a one-suited flop

[BlackAces]

$3-$6 game last night. Table is fairly weak-tight from what I've observed, a dream game, really. I limp in late position behind two other limpers (one EP, one MP) with

K[img]/images/graemlins/heart.gif[/img]5[img]/images/graemlins/heart.gif[/img]3[img]/images/graemlins/heart.gif[/img]

BB bets, EP limper raises, MP limper folds. 7 1/2 SB in the pot, and it's 2 to me. I don't have any specific reads on either player still in the hand, as I've only been at the table for 15 minutes or so.

Your play?
