Snow White chuckled. "Oh, there is no real..'magic'...needed to enslave them. All you need to do is just show them your superiority for hours on end. Fucking them, till their minds are weak, and then rebuild it, however you see fit!" She said, "Though, I could make some potions to turn some of those peasants into our bimbo slaves!"
"Oooohhh. Fucking them into submission?" Anna said, with a grin. "That sounds fun. Doesn't it sis?"
"Oh, yes it does." Elsa replied back. Stretching a bit, she stood up. "How about we start with that hunky boy toy of yours."
Anna gave a sinister chuckle. "Me and my sis, fucking my boyfriend until he's our sex slave. Now THAT is a true bonding experience."
The two sister chuckled evilly in unison, as they followed the hooded figure to the captured Kristoff.

(10 minutes later)
Kristoff awoke after having been ambushed and knocked out by the dwarves. Looking down he found he had been stripped down, and his feet, were frozen to the ground and as he looked up he found ice chains holding his arms in place.
"Oh, look sis. He's finally wake." Elsa said coming into the room.
"Mmmm. I bet he is still a bit sleepy. Isn't he Elsa?" Anna said, as she swayed her hips entering the room.
"Anna? What did they do to you?!?!"
Anna chuckled. "Oh, they awakened the evil slut that I was always meant to be, dear Kristoff." she said as she rubbed her hand on his cock.
"Anna, snap out of it!" Kristoff pleaded, hoping to find some small shred of the Anna's formerly bubbly self.
"Mmmm. Yes, that's it. beg to me." Anna said, followed with a cackle.
Kristoff, could not believe what had happened. Both Anna and Elsa, had been turned into completely evil sluts. Just then he felt something wet touch his dick. Looking down he saw Anna, licking his cock, getting it nice a lubed up, for the fun she and Elsa were about to have with their soon-to-be sex slave, as Elsa created herself an ice strap-on, to fuck his ass with.
"Alright bitch! Let's see how tight your hunky ass is." said Elsa, as she jammed the cold strap-on into Kristoff's ass, and began to fuck him.
Anna continued to lick his cock getting it nice and hard. Once she had done that, she looked at it. A wonderful 8 inches of masculan meat, covered in her drool. Taking it into her mouth, she began sucking on Kristoff's massive penis. Loving the taste of cock, and the feeling of being evil, she was in complete bliss!
