BooM!
Almost a full month after Halloween, this is finished. 

Overall 12 responses to the "Humble Treat" poll were submitted. 
Out of those there were a couple that sounded quite good, though many were just too lewd for a "humble treat" (Teaches ya'll for not voting enough to get the treat level up ;D)

In any case, the suggestion that sparked the idea was:
"Amber and Aisty flashing the guests of a Halloween party a small peek under their costumes".
Now I sort of think this isn't 100% what the original poster had in mind with "peek under their costumes", but again... Should have had more votes in ;D 
So instead, they're showing a little thing they did.... which is co-ordinate matching panties!
SPOOOOOKY panties at that!

Also, for anyone interested in who they are dressed as:
Amber - Star Guardian Jinx
Aisty - Star Guardian Ahri
