2/4 Facing aggression on good flop

[Octopus]

Absolute 2/4 8 handed. Middle position poster.

One limper and the poster checks. I have QJs on the button, and in a fit of insanity, I click call instead of raise. (May the poker gods forgive me. If anyone cares, I am often accused of significant *over* aggression pre-flop in hands with a poster. Alas, not this time.) The blinds come along and we are 5 to the flop for 5SB.

Flop is Q72 rainbow, one of my suit and I am happy. Blinds check and limper bets. Poster now raises. I am slightly less happy.

You?
