KK, am I a tourney donk? (25 NL)

Sorry for a basic question. UTG is 17/14 over 29 hands. CO is 40/5 over 70 hands. SB is a FTR poster (giallorosso) - 16/8 over 113 hands.

Am I being a tourney donk here?

Preflop: Hero is BB with Khttp://www.flopturnriver.com/phpBB2/...miles/club.gif, Khttp://www.flopturnriver.com/phpBB2/...iles/spade.gif.
UTG raises to $1, 4 folds, CO raises to $2, 1 fold, SB raises to $8.75, Hero raises to $24.25

What else could you do?

looks great to me. its either that or fold

SB has AA, QQ or red KK, plus the CO who is an x/5 has put in a raise PF. I might muck this...
