Pretend that you don't know him

"I don't know what you are talking about, sir" You say firmly trying to hide all of your emotions raging from anger to shame "I have never seen you before and would very much appreciate if you would stop talking and help me to guard the village instead of making such indecent proposals"

He narrows his eyes looking at you attentively "Oh... that moronic coders reused appearance both for a guard and a whore..." then he studies the sisters "And those two are adventurers... Shit" He pauses for few seconds looking embarrassed "Ladies, I am deeply sorry. I recently had a very good time with a local whore who looked just like her and I assumed that you all are NPC whores and I like to roleplay some lewdness toward NPCs matching my appearance" sometimes adventurers use words you can't understand. You really should learn what 'roleplay' and 'coder' mean. "I see that you are only level two archers. Let's go hunt some goblins, OK? I'll keep you safe" His tone changed completely and you can't quite say why "And to make for my rudeness I'll let you take all of the loot"

"Uhm... Neesa, what do you think?" Mika asks after a brief pause. She seems far from being ready to trust a guy who offered her and her sister to orally pleasure him.

As much as you despise this guy together with him you should easily defeat both the second wave and possibly the third one.
