Requesting some guidance

I do not play a lot of ring game. But I have started playing more lately and I run into a lot of situations where I am not sure of the best move. Here is one from today, the site offers no hand histories so I have recreated it. Full 10 man table, .25/.50 NL.

Pertinent stacks:
Pyroxene: $51.25
jewito: 49.23

jewito is the SB
Pyroxene is the BB, dealt :As: :Kd:

UTG: Fold
UTG+1: Fold
UTG+2: Calls 0.50
MP: Fold
MP+1: Fold
MP+2: Fold
CO: Posts 0.50 and checks (just sat down)
Button: Fold:
SB: Raises to $2.25
Pyroxene: Calls $1.75
UTG+2: Calls $1.75
CO: Folds

Flop: :2s: :Ks: :5s:

SB: Checks
Pyroxene: Bets $4
SB: Calls $4

Turn: :8d:

SB: Checks
Pyroxene: ????

I have TPTK and the nut flash draw, but the SB has called my 60% pot bet on the flop. The SB is not an idiot and I have a very tight image.

Do I bet out here and cuss if I am reraised hard? Do I take the free card?

Pyroxene remembers he has both TPTK and the nut flush draw and bets hard and strong against the guy drawing to the flush/holding a worse king. Kill him, big man :)

lead turn, check-raise river on spade, check-call river on blank

check behind on the turn

pot control, draw to the nuts, don't want to get blown off the best hand
