Dudley Dursley recognized that his female cousin, Harry (or Harriet or whatever other name) Potter, is growing up to be very hot and at the summer of her fourth/fifth year, decided to fuck her. He gets help from Vernon who thinks its fitting that the freak serve her betters and together the two spike her food with alcohol and aphrodisiacs. Then when she’s lusted out of her mind, Dudley brings her to his room and fucks her. He does that a couple times until Harry realizes that she likes being dominated by him and they spend the summer just doing it everywhere around Private Drive. Petunia who loves seeing Lily’s daughter become a debaunched whore decides to teach her how to be the perfect housewife, buying slutty clothes, making Dudley’s meals, being ready for him when he comes home, etc. Vernon could join in the fun too. It ends with an epilogue where Dudley comes home fifteen years into the future with a perfect life: his career is doing well (thanks to Harry and her magic), he’s wealthy and well-respected, and he comes home to a slutty, buxom and heavily pregnant wife that he can fuck whenever he wants. Maybe make it a parody of the actual Epilogue where Harry goes with Dudley to Station 9 ¾ for their kids- James Sirius, Vernon Dudley and Lily Petunia- to go to Hogwarts and comes home for Dudley to fuck her.
Things I Would Like To See: Submissive Harry, Slutty Harry, Harry’s child knowing she’s a whore, Pregnancy King, Cock Worship, Dirty Language, Dom Dudley and maybe some Public Sex
