Always the full porn star 5 step process for an 18 hour cleanout of the entire lower GI tract under certain conditions: if she is spending the night, enjoying a sex club or house partly where she knows she will be enjoying double penetration, gangbangs, dating a man with a cock over 10 inches as she knows the back her vagina and cervix is going to need a break.
My wife started out anal only for as birth control after a pregnancy scare, missed 3 periods, after losing her virginity with our much older and experienced boss. She got really good at doing it by herself until she moved in with me. We didn't have sex for another year but I was more than willing to assist as an already trained recently divorced cuck performing clean up duty for my first wife and my future wife's lovers. I know those first hundred or so men before she got on the pill appreciated it as much as the hundreds since. I do as well as I have to eat her partners cum from where ever it is ejaculated and clean her Bulls cock ass-to-mouth if he wants to switch from her ass back to her vagina unless he wants to break and go wash himself.
I'm so good at giving enemas, we have it down to a science, that she had me assist one of her pregnant girlfriends who was consistently constipated deal with her issues a couple of times a week her last trimester.
