MistressJudy,

I've heard of a few people doing this but I've also heard it can be dangerous. Although I have done this before and have fantasies of my Mistress forcing me to do this. I guess the thing to worry about is introducing certain lower intestine bacteria into the upper intestine. I hear this can make you pretty sick. I've read some on this and it seems it depends on how much you ingest and how often you engage in this activity.

Have fun and feel free to contact me to talk more about this subject if you like..
