I love the idea of a feeder/feeder dynamic that starts off with a dominant feedee and as they get bigger they become more submissive and docile. 
The feedee starts off by being demanding and taking charge of feeding sessions, ordering exactly what they want and being a commanding force whilst they do it. But as time goes on and they become heavier and slower, they start to become more reliant and submissive towards their feeder, who also starts to take the lead in every aspect of the feedee lives.
And before the feedee knows it, they are 500lbs, big as a whale and completely under the feeder’s control, finishing everything the feeder puts in front of them without a second thought. Struggling to even walk without the feeders help, making them complete dependent on the dominant force that is plumpingthem up towards immobility.
