made flush on the turn, how is my line?

[srm80]

bodog .10/.25, 9 handed

i have been at the table for 15 minutes, no reads on opponent. villian has $25, I have $57.

UTG2 raises to 1, I call with A [img]/images/graemlins/club.gif[/img]6 [img]/images/graemlins/club.gif[/img], folds around.
($3.60)
flop: 3 [img]/images/graemlins/club.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/club.gif[/img]
villian bets $1.60, I call $1.60
($6.80)
turn: K [img]/images/graemlins/club.gif[/img] (3 [img]/images/graemlins/club.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/club.gif[/img])
villian bets $4.60, I call $4.60
