flush on paired board

[dan]

table is tight, i have raised preflop about 7 times in last 2 orbits and stolen the blinds, the SB called my button raise once and folded to my cbet after thinking for ages, i havent shown down anything at all.

SB player is kind of loose, just a semi loose donk...

Im holding KsJs in CO, folded ot me i make it $1 folds to SB who calls, BB folds

Flop
3s2s3c
SB checks, i bet 1.25, SB calls quickly

Turn 5d
SB checks quickly, i think for about 4 seconds and check

River 5s
SB bets $4 into $4.5~ pot, i just call? or push?

EDIT - i had full buying (25) to start, SB had around $15 to start hand.

the board is paired twice, right????

If the board reads as is then this is a fold/call situation, leaning towards a call.
