Spewing with overpair

[RacersEdge]

50 NL

Me: $35
Villain: $60 (Was like 25/5, but just 30 hands.)

2 limpers

I rasie to $2 on the button with Q [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/heart.gif[/img]- only early limper (EL) calls.

Flop = 5 [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] Pot = $5

EL bets out $5.25. I called and proceded to call off my stack on the turn and river. (Turn = 3 [img]/images/graemlins/club.gif[/img])

What's better - raise to say $15 on the flop - if he calls the raise and bets out turn, OK to fold?
