The struggle

With their roles seemingly cemented, Isaiah wanted to try anything he could to get back his family or at least make them see him as more than he was now. So, while Dilly was taking the girls on another vacation or trip or dinner, Isaiah was at home. Training. Both he and Bella were training thanks to the bargains Isaiah struck with Bella to fuck her if she put in the effort. This alone was seemingly enough to motivate the horny Bella as she began using furniture and weights to lose that weight and train her legs and body.

Eventually, through visualisation to see Bella and him as a human, he could finally look at Bella as an attractive woman. Not some fat lard, but a muscle mommy with control of her drool. Isaiah hated to admit it, but while visualising Bella and him as humans, he was opened to a whole new world of pleasure, honestly loving how Bella held him in her arms now and tried to make them both satisfied in every way.

Bella even helped Isaiah when he told her about wanting to get his family back, as Isaiah promised to keep taking care of her, and that they both knew how amazing of a mate Dilly was, so he could AT LEAST satisfy her sexually, something Bella mournfully agreed to as the two of them waited for the right moment when Dilly would take them out for an extra long time, but not so long that they would call a babysitter or something who could stop them.

So, when that moment came, Isaiah grabbed out a paint bucket hidden in the back of the shed after struggling to open doors and move chairs, painting all over the house to tell Eleanor and Cynthia who was the real Dilly and who was the real Isaiah, explaining everything repeatedly. How Isaiah was mind-swapped with Dilly by some magical amulet, and how Dilly now kept the amulet from Isaiah and refused to use it to revert them, acting secretly cruel to Isaiah as he did so.
