She gorges on high calorie foods and bloat up fueling her silk production. Her jiggling backside squirt out copious amounts of silk to build a large hammock to house her growing body. The scent the silk gives out, attracts servants to do her bidding, via bring her more food to much on and get fatter. Not complete mind control, basic mental suggestions and the pheromones the silk give off is the cause of it. Those who are stronger and try to resist are taken and are given the crapier position. like bathing and kneeling her long large wobbling backside to coax out more of the special silk and get frequent point blank farts to the face. They use the silk to build onto the hammock, now making it resemble somewhat of a castle. Growing longer and fatter, she continues to eat more and more, producing more silk from her backside to where it just oozes out and squirts every time she farts. She goes around on her portable throne made out of silk to patrol her key area, leaving a mess everywhere she goes while someone has to clean it up.
Thats what I got so far.
