Fire again on the flop after 3-betting a 2+2er preflop?

Party 3/6 6m 6 handed

CO is a 2+2er, we both know each other's secret 2+2 identity. He can identify himself if he'd like.

No read on UTG because I'm 4-tabling and PokerAce isn't working and I'm stupid. He hasn't done anything to distinguish himself from the masses as far as I've been able to notice.

PREFLOP
UTG limps, MP folds, 2+2 raises, I three-bet (?), blinds fold, limper + 2+2 call.
