Starting now, and from now on, whenever anyone says "commando girl" to you in any way, you will feel an urge, a need, to remove your underwear, and you will do this as soon as you can do it safely and discreetly. What's more, once you have removed your underwear, you will find that you are unable to wear underwear until the end of the next day. Of course, if you are not wearing underwear when someone says "commando girl" to you, you will simply find that you are unable to wear underwear until the end of the next day.
