“I know it’s difficult for you to understand, Grace, and your head is positively swimming right now, but when your father died, I was so lonely. I really had no idea that he would hypnotise me into becoming his mindless, obedient sex slave, or that he’d make me want to do the same thing to you. Seriously, I’ve been so wet watching you get conditioned!”

As the final video ended, Grace turned her attention to her mom and giggled.

“Things are going to change around here from now on! We’ll fill this house with our love as we worship His cock together and carry out His commands like the sex slaves we’ve become. Doesn’t that sound blissful, darling?”

Grace beamed and leaned in and kissed her deeply for the first of many times to come.

I don’t know WHY–I guess ultimately squicks don’t make any more logical sense than kinks–but the one exception to my incest squick, the one kind I can actually enjoy, is a mother/daughter or two sisters being controlled by an unrelated third part. That’s actually pretty hot, and this is a hot example of it.
