Delayed action

Hi, id like to push something up my bum that has no effect whatsoever for maybe ten minutes or more, then works quickly to make me shit, i want to put on a diaper and go for a walk, and getting far enough away from home so i cant change my mind.....any ideas ?

There will be a lot of individual variation on this.

I know, thinking along the lines of a "container " of some sort that has no effect on its own, maybe contains liquid glycerine, and either the whole container melts with body heat, or has some form of meltable plug to let ingredients out ..

Before anyone says anything....im well aware of soap, suppositories, mini enemas etc, but they all start working right away.........i seek the delay.

Freeze glycerin sups in freezer

Bisacodyl will have a 15-60 minute delay.

I push three suppositories up my bum, I can,t feel them but after twenty minutes I get a very sudden and powerful urge to go, so powerful if I,m not standing next to the toilet I have some very full underwear.
