I'm surprise no one has opened a thread regarding this.
I am seeing a lot of people wanting to fulfill their fantasy of serving as a toilet slave and it is not as easy as you may think.
For those of you who still want to go forward there are some things you may need to consider. Here are some guidance from my experience:
Don't think you are eating poop, everything is in your mind, instead think you are eating your favorite dish, it is way easier like that, believe me.
If it is your first time you will probably be nervious, don't serve several girls at once, try first with one and the next day you can go with one more, gradually you will feel more confortable serving more girls.
Asking your mistress to close your nose will help you while swallowing, otherwise you will find yourself wanting to puke, and we don't want that, right?
