There’s something you don’t know about Me as your stepsister. You always wondered about Me, you always fantasized about Me being a bad girl. That’s because deep down, I’m a little Demoness. What do you think our stepparents will think when they find out where I really came from? Poor you, just the spawn of regular human beings. The Devil is My Daddy. You’re too pathetic to be My full stepbrother. You’re just a weak human male, and I’m going to steal your seed to sacrifice. Cum for Me, cum for Satan, you know this is what you really need!

You have something underneath that masculine exterior. I know what it is, and I know how to permanently reprogram you. I can sew seeds of sissification into your brain as many times as I please, unlocking your feminine potential. When My trigger words hit your ears, a switch flips and you can’t control your femme urges. I train you to become the most obedient cum slut. Squirm for Me as I melt your poor soft mind, and you can’t help but crawl back to Me over and over. Enjoy your new sissy purpose, because this is the real deal. Part 6
