SH rookie post 2: 99 issues

[DCWildcat]

I know not raising 99 is a sin, but this pot is destined to be 5-way, which makes me think set value. None of these opponents, including the BB, are folding PF.

Preflop: Hero is SB with 9[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/diamond.gif[/img]. CO posts a blind of $1.
UTG calls, <font color="#666666">1 fold</font>, CO (poster) checks, Button calls, Hero completes, BB checks.

Flop: (5 SB) 2[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
<font color="#CC3333">Hero bets</font>...

After hitting myself for not raising PF, I attempt to salvage dignity by donking an ugly flop. Was that another bad idea?

I see no reason to see a turn.
