AA-simple turn decision?

[Swisher]

Hello everyone how are you? My first hand post so be gentle please. Just wondering if I should call this down or fold. No reads.

PokerStars 1/2 Hold'em (10 handed)

Preflop: Hero is UTG with A[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/diamond.gif[/img].
<font color="#CC3333">Hero raises</font>, <font color="#666666">2 folds</font>, MP1 calls, MP2 calls, <font color="#666666">5 folds</font>.

Flop: (7.50 SB) 9[img]/images/graemlins/heart.gif[/img], 3[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, <font color="#CC3333">MP1 raises</font>, <font color="#CC3333">MP2 3-bets</font>, Hero calls, MP1 calls.

Turn: (8.25 BB) 8[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>
Hero checks, <font color="#CC3333">MP1 bets</font>, <font color="#CC3333">MP2 raises</font>, Hero....??
