I love it so far. Wouldn't mind seeing an entr that's a flashback to the first time he broke Lily. Also maybe Lily accidentally slips her son a gender transformation potion that's not only permenant but made using some of Dudley's cum thus tying Harriet to him.. Jsut a thought.
Hey, this is great!
While I'm not a fan of cucking, I really enjoyed reading this and how alpha Dudley is! I find the new universe you've crafted intriguing and I desperately want more. I don't have any particular qualms about the girls/women you plan to use, but, at the risk of being cliche, my favorites would be Hermione and Ginny. However, this is because these are two of the most important girls in the world to Harry and Dudley actually taking them for his own would be actually cucking Harry. Anyways, I really enjoyed reading your story and I hope you write lots, lots more!
Fucking hot!
