well the day before an anal scene i usually don't eat past 6pm then ill do an enema at like 12am ( i always stay up till 1 am ) in the morning, go to makeup and right before my scene ill do half an enema, just luke warm water tho. then im ready to go! somtimes if my scene is not till later in the afternoon and i can't wait till after the scene to eat then ill take an Imodium ( an anti-diarrheal ) i don't recommend taking one unless you are really really hungry..it'll plug you up for days, haha. most of the time your safe to eat somthing small before an anal scene cause it takes awhile before you fully digest your food.( i don't like taking the chance) the thing you need to stay way from is coffee, that will go right through you. anyway most girls in the biz who do anal know their body and what they need to do to get ready this is just what i do to enjoy eating my ass of somones cock, corn free! ewww. gross thought.
