Misclick flop raise, scare card hits on turn

[DrewOnTilt]

Villain in this hand is fairly loose - 42/16/38 WTSD. I have not seen him get out of line much postflop, though he does tend to show down a bit too much with weak pairs.

I didn't mean to raise the flop - I meant to peel/fold the turn unimproved (though the raise would not terrible with my overs and backdoor draws). Then a scaryish card hits so I bet. Decent bet, or spewy given my read on him?
