Does watching someone poo help, like a sympathy barf does sometimes. I'm regular once or twice a day thankfully. I don't get stuff shoved up there and its no surprise porn babes doing anal all the time have some difficulty. Isn't the thing to starve without solid foods day prior to the scene. Without solids afterwards because ass muscles aren't so tight.

Some scatter seeing this stuff or talking about it.
