Your great-granddaughter turns 18...

Your great-granddaughter Emmie wasn't raised in your house. Partially because your granddaughter Emma Jr. moved out because the house just got really crowded. And the sex was just non-stop. After you bred your own granddaughter all of her classmates that you turned into your sex slaves were coming in and out of the house constantly and parading around naked. The sex couldn't be contained to the bedrooms. It quickly became a place that wasn't appropriate for children.

And so compared to your other progeny Emmie had a fairly normal life. Her mother Emma Jr. still fucked you and her dual daddies (your sons Jacob and Zach) quite a lot, but Emmie had no idea this was happening. And she knew you only as her great-grandfather. She didn't know you were also her father.

[To remind you of Emmie's twisted family history. You bred Emma's best friends Isabella and Sophia, who though married to Zach and Jacob respectively, are sluts who truly belong to you. Then you had Isabella and Sophia's first-born sons Zach Jr. and Jacob Jr. breed Emma by cumming in her pussy at the very same time. That's how Emma Jr., your granddaughter was born. Years later, you bred Emma Jr. on her 18th birthday (in front of many of her schoolmates who you also had slut trained), leading to the birth of Emmie - your great-granddaughter who is also your daughter.]

To be honest, you were busy living your best life - surrounded by endless beautiful women and regularly breeding the most beautiful ones. You knew that off somewhere Emmie was gestating - getting ripe for your pickings, but you didn't fret much over it.

So you didn't think about getting the ball rolling on Emmie being trained for you when she turned 16. So Emma Jr. didn't tell her daughter about the family's big incestuous secrets. And since Emma Jr. didn't even know that she had ever consumed Slave4U certainly didn't know to give any to her daughter.

So when Emmie’s 18th birthday rolls around she has had no preparation whatsoever to be your slut. She’s never even had a single sexual thought about you her whole life. In fact she's a bit disappointed when her mom tells her that she has to spend her 18th birthday party hanging out with her great-grandpa John and her grandma Emma.
