Soap has long held a special place among the punishments imposed by mothers to punish misbehaving offspring of all ages. It also proves to be an excellent option for governesses who are responsible for disciplining charges of all ages. Here we are only considering its use with those who are 18 years or older. But as with many traditional nursery punishments, it becomes highly embarrassing when a disciplinarian—parent or governess—resorts to its use with adults who have been naughty.
There are two main types of soap punishment. One is insertion of a soap bar into the mouth, with the recipient required to retain the soap in his or her mouth for a specified or indefinite time. The second is insertion, usually of thin sticks of soap, of the soap anally.
Soap is most commonly employed as a punishment for use of unacceptable language, especially the two most heinous four-letter words. "You need your mouth washed out" is a frequently-uttered statement that precedes the punisher's imposing the punishment, usually in the mouth.
It is most effective if the disciplinarian first rubs the soap using hot water to work up a warm lather. Leaving as much of the lather on the soap bar as possible, the bar can then be inserted in the open mouth of the offender. It should be moved around within the mouth and then the bar should be left projecting from the mouth, with the offender being required to hold it in place with his or her teeth.
While the soap bar may be removed after a certain time, being required to hold the bar with the teeth while being spanked, for example, is a good ancillary punishment. Normally, the offender is warned that there will be severe consequences—possibly added punishment such as caning—if the soap bar is allowed to drop from the mouth.
When the soap bar is removed, the offender should not be allowed to rinse for a further period of time. This means that the lather will remain in the mouth and the punishment in effect will continue since the harsh taste of the soap will remain until a mouth-rinsing is permitted.
Soap punishment is highly embarrassing because it is associated with juvenile discipline. The second form—anal insertion—is especially shameful because it exposes the private parts to view of anyone who has been permitted to observe the punishment. The offender may be bent over or on a chair and ordered to hold his or her bottom cheeks open.
This position will focus attention on the male or female genitalia as well as the anus itself, which few enjoy having others see. Insertion should be done slowly, both to prolong the exposure and to make it easier to get the soap stick into the rectum. Care needs to be taken not to jab it in as there is a danger of piercing the rectal walls. If a thin stick of soap has been cut from the bar, it can be inserted much as a rectal thermometer.
