Context: My very first session, with special permission to make a Siren Rogue. She had been recruited by a human along with a kitsune. The trio had been summoned by a king to be debriefed on a mission. It should be noted that my Siren is generally very sarcastic, sassy, and mainly wears a very revealing outfit.

Siren: -arrives stylishly late and successfully charms numerous guards that she had flown into-

King: Oh, I see that another recruit has joined you.

Human: -obviously displeased- Yes, unfortunately.

Siren: -giving an exaggerated curtsy to the king- It’s a pleasure.

King: -blushing- Indeed it is.

Siren: -flirtily- Are you married, my king?

King: I was but unfortunately, my wife was taken from me a few months ago.

Me (going OOC): I’m going to hit that

DM: -laughing- I’ll allow it.

Human’s player: -also laughing- Wait, seriously?

DM: Yeah.

Siren: -doing a proper curtsy with a wink- Then perhaps a courting could be arraigned upon my return.

DM & King: Uuuumm sure.

It wasn’t until the next story, after a few new characters had been introduced, that the other players (excluding the DM) found out that I had been serious and she was now the queen of a kingdom.
