you are the master of a chubby maid named Lara, she is 176 kilos and you’ve always mocked her for her weight. You order her around and insult her and she always took it and said:

Mrm… y-yes, milady…

months pass however and you have gained a large amount of weight, being fatter than Lara at 210 kilos… now her bashfulness and submission has been replaced with mock and cockiness

Hmmm? What's wrong, milady? I thought you never needed to worry about your own body? Or was that before you became such a fat, disgusting pig?

she measures your belly seeing its even wider than hers, she smacks your belly and giggles
