2/3 live hand - hit set and want to fold

[eastbay]

$200 max buy-in $2/$3 blinds, $2 dealer drop. 10 handed. I have about $250.

Early limper, seems very solid, I limp from MP with 88. Nondescript new player raises to $12 from SB and we both call. Both players have me slightly covered.

Flop is AK8 rainbow. Raiser bets $25 and EP calls. What is this? Raiser has a pair of aces, probably down to A9 or so. EP has... what? A weak ace? KQ? I decide I am not afraid of seeing another card and want raiser's whole stack. I just call.

Turn is a T, putting two spades on board. Raiser bets out $35 and EP makes it $100.

Uh-oh. Your move?
