Im not a doctor, so take this at face value.

I would recommend full colon enema. Keep flushing it out, over and over and over again. Keep going until all expelled liquid is clear. I recommend doing this over multiple nights leading into the session. And watch what you eat as well - go lighter leading into the scheduled session.

30 mins prior to the session - ensure everything is expelled and clean. You can do this by yourself with a finger or a toy. This way, you ensure you are clean and ready for whatever your mistress chooses to do. There will be nothing in there. Perfectly clean = best results during session.

Again, this assumes a healthy digestive system. Do not follow this if irregular discharge or bleeding. Use common sense.

I hope this helps. I do it, but for other reasons, which I will not share on here.
