Son takes mom/wife from dad, who is MC

Simon is a known cuck, and his children have lost respect for him in that aspect. Simon wasn't too far off the mark, but he wasn't quite on it either. Because, although Simon wanted his family to let go and start fucking each other, some weren't entirely going that way, and had their own fetishes to pursue.

For Harvey, he wanted to fuck his mom, but he also wanted to fuck his grandma since they looked like sisters and were like busty supermodels. For Abigail, she also wanted to pump Megan with cum, as well as her super sexy sisters, who made fun of her for her obvious boners and short stature that made her seem like the youngest, despite being the second oldest sister and third child born out of the 6 kids between Simon and Megan. However, there was a problem with this, as although Abigail also wanted to pump these bitches with her cum and cock, she was also a big-time masochist, and after finding her friend, Hattie, with her parents as their bull, Abigail worried she was also a cuck, as she got off to the thought of being replaced. But that's what the main focus of granting others' wishes lay in, granting Simon's wish, as Abigail wasn't simply a cuck, as although she would've been happy to jerk off as one, Abigail was unknowingly and hugely into an unknown genre of clone porn where a superior version of oneself takes the original's life or place. She especially loved the doujin: China fuku de TS suru yatsu (real doujin btw), and so, without any prior context, thought she was just a masochist or cuck with a love for TS.

But thanks to Simon's wish, Abigail could now enjoy her wish being fulfilled, allowing the cuckery to begin. However, Abigail didn't know that's what she wanted, so one day, Abigail was met with a copy of herself, one that was a little dazed but knew she was the clone, listening to Abigail as she tried to hide this secret. Abigail couldn't help but have her mouth water at her copy's body, henceforth called A2. Abigail had to admit, seeing her body in a third-person perspective got her hard, same for the clone, although the clone clearly had a bigger ass and tits, if only by a little bit, something A2 held over Abigail in a cheeky manner, using it to establish dominance as she stepped on Abigail with her soft foot before inserting her pussy onto Abigail's cock, impaling herself on Abigail's shaft.
