maid fart fetish idea

in a fantasy world, you end up buying a slave to work for you as a maid. for her food, you have her eat the gassiest foods you can think of, and drink fizzy drinks. this is a daily thing for her meals.

you make her wear a maid outfit of your design.

but the thing is, you treat her very well, so long as she obeys you.

for a few hours of the day, she is to follow you around. during that time, you undo a spell (and she is now capable of farting whether or not she wants to in your presence). she does not know of this. so, during this time, all the gas that has accumulated over the day finally can make its escape. some are silent, some are loud, some are long and medium-sized. the spell reactivateds automatically at 5am every day. so from 5am - 5pm, the gas builds up in her, unable to escape (on top of the fact that the food you have her eat causes more gas).

the way the spell works, is it's a musle controlling spell. it controls her rectal musles to tighten slowly. until it's clenched.
