Badly for Isaiah

As things continue down this path, Isaiah is kept around, but he continues to be sidelined.

• The girls take Dilly out on special 'thank you' dates without Isaiah
• Cynthia convinced Isaiah to do some cuck play, with Isaiah always as the cuck
• When Cynthia wanted to try pegging, she only used Isaiah
• When Eleanor finally gained the courage to ask out Dilly, Cynthia bridged this divide to include Isaiah, backfiring on Isaiah as Eleanor saw Isaiah's loss of power in this family as him becoming pathetic, so she only ever stepped on his cock and treated him like a masochist while Dilly pleasured her holes
• When they tried edging Dilly and Isaiah, Dilly broke through his cock cage for a couple hours and used all that pent-up lust to fuck the girls for days while Isaiah was forgotten and left in his cage, the key conveniently lost when he wanted out to join them in sex, rarely getting let out and instead getting teased.
• The children the girls had were often dropped on him to take care of.
• Cynthia and Eleanor publicly married Dilly, somehow to the praise and delight of Cynthia's and Isaiah's parents in an enormous and elegant wedding that saw Isaiah's mom and mother-in-law seduced.
• They always rooted for Dilly during competitions

Eventually, they stopped with the pretences altogether and decided the best thing for everyone would be to return Isaiah to his status as a pet/cuck, but as a human. All his rights were revoked in the process. Isaiah's birthday was given to Dilly, his legal identity, and everything else. When going out, they always introduced Dilly as their daddy/lover and Isaiah as their pet-cuck. They would try all sorts of things out on Isaiah but treat Dilly like their idol, always sticking by his side, developing bigger tits and asses to his liking.

Eventually, any warmth for Isaiah was only given as a cold smile while fingering his asshole or wasn't there at all, replaced with the expression of an angry dominatrix looking at a disqualified male. They would feed him in a dog bowl, made to throat polish their strap-ons or lick up any cum and orgasm juice spilt on the floor. Cynthia would often work in the kitchen with only an apron, having Isaiah sit on the bench with his dick, shrunken from the cock cage, sitting there, hard, in an attempt to look mighty in his now scrawny and girly body as Dilly is attracted by the scent of a woman at work, leaving the cooking to Isaiah while they fuck in the kitchen, stripping down to nothing, usually causing Eleanor to come in and join them or walk through the door, annoyed that they left her out, completely ignoring and not acknowledging Isaiah unless she has to shove him out of the way, giving him a disgusted look more than before because she's surpassed him in height.

On the few occasions they've had to use Isaiah as a father, he's never looked like a man. His body has long since given up that attempt at masculinity, and Cynthia and Eleanor happily, smugly, and lovingly pull him on a leash connected to a visible collar around his neck, paying no mind when a woman comes up to him and gets super horny, their instincts as women overrode by the desire to dominate this twink. At least until Dilly makes a surprise appearance, making women start squirting on the spot as they swoon at him.

Dilly's even become so attractive to the female audience and men questioning their sexuality that all men and futas lose their dicks in place of a vagina, and these women or genderbent females instantly grow big tits and asses. They then devote themselves to Dilly and take his seed before going back to whatever they were doing, becoming harsh towards the men and enticing the women to join. If they're married, they now add a bit of testicular **** to their bedroom play and act super harsh in the bedroom to try and get their men to scratch the same itch Dilly did in their cunts. Hell, even the offspring of Dilly is different, as Eleanor regularly admits that not only has Isaiah's sperm become even more pathetic and mostly water, but all of Dilly's offspring are simply superior males and females, and Eleanor's simply happy she married such an alpha stud.
