I have an upcoming session coming up which hopefully will involve heavy strapon. I like to eat and have a big appetite but am going to try to eat lightly for a couple days before the session. I am thinking a lot of soup and liquids, smoothies, coffee and salads hoping this will keep me filled up and the volume in my digestive system low.

I will do my best to clean out before the session. In particular I am wondering if there are any particular foods to avoid to keep my volume low and make cleaning out easier.

I think people overcomplicate this, not saying you, but I've sessioned for 15 plus years and always am paranoid about being clean going into sessions.
Wha I've learned for me, not saying you is a few things
1 - eat light the day prior, it's not so much about what, as when and volume.
2 - avoid alcohol and caffeine for 24 hours, maybe this is not relevant, but I do
3 - the DAY of session, after BM do a water enema, as many times until clear. I'm talking about the small squeeze 1's, not deep.
4 - then 2 hours prior, at least 1 more enema,
5 - all this the day of, then my 1st meal is en route some light crackers, and H20.
6 - lastly, if I feel "full" I also take empty enema to session, ready to use upon arrival for 1 last cleanse, and I do not think any Pro-Mistress would be upset with that to ensure clean.

A lot of that depends on the time of session, for me AM sessions are a NO go, and sessions after 8 pm take additoinal preps, but if I'm sessioning between 12-7ish I've had some 100 plus and never had a single unclean moment using this method. I can't recall which Mistress told me this before a session, but for me it was golden
Again, no clue what foods to avoid, other than the obvious spicy things, as it's more about your own schedule that you are already aware of,
GOOD LUCK

I actually already had the session and this is good advice and pretty much what I did except that I started with the eating light and water enemas a few days before. I am happy to report it worked great as the Domme said I was squeaky clean back there. I don’t have a lot of opportunity to session anymore but I will try to repeat this process when I do. I have meant to make a post about what I did on MF where I also posted this and got alot more responses.

my butt sluts swear by taking these days before

Thanks I’ll give that a try.

Unless you're doing depth play, I think you, like many others, are overthinking this.

You don't actually need to do much unless you have an especially touchy GI system.

If you're not doing depth play there isn't much to worry about because the play is occurring in your rectum. You're just rinsing that out, which is easy.

Special diets and the like? Not really needed. If you're regular and tend to poop at the same time every day then just schedule your session after that happens.

Psyllium husk is great if you need fiber. Fiber gets you movin'. But it can also make your poops too soft and if mixed with water it will get messy.
