Bet and Raise On Turn

[MainEvent]

I've read a decent amount here but haven't posted replies or hands very often. This one is bothering me from last night so any input would be appreciated. (I use the term hero very lightly in this post)

SB = 70% VPIP 5% Raise 1.5 AF
UTG + 1 = slightly loose but pretty normal player. Not great, not horrendous...nothing remarkable.
Both over ~40 hands

PREFLOP:
UTG + 1 calls, Hero (UTG + 2) RAISES with AQo
MP calls,SB calls,BB folds

FLOP: Q[img]/images/graemlins/heart.gif[/img]8[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/spade.gif[/img] Hero has no [img]/images/graemlins/spade.gif[/img]

SB BETS, UTG + 1 RAISES, Hero 3 BETS, MP folds....call, call.

TURN: J[img]/images/graemlins/diamond.gif[/img]
SB BETS, UTG + 1 RAISES, Hero...?
