I have been thinking this for a while, during the threesome with the Krampus they said you're a bad boy/girl and you need to be punished, but considering what Vicoria has done so far she is a whole level of bad girl, maybe she will receive a little visit from the Krampus and start a "hell of foursome" where she could be fuck by the three Krampus or use one of the toys you gave her on the green submissive Krampu while been fuck by the others two. That could be an interesting CG, besides that could low Vicoria's libido a lot even after what she does with Arion.
This is just a random thought, most likely never will happen since this game is mostly M/M(which is why I love it so much) but it could be a good scene specially if you can play as a Bi MC.
