I'm with lucy, what soap would taste good?
I'm curious to know who would actually enjoy sucking on a bar of soap.
The only soap I have in my place are Jergens and Dial.
I pick the Jergens because the smell isn't so strong. I also have the baby bars you get in hotels, which are much easier to put in your mouth and hold there, without biting into them. I have to suck on it, and the longest I've gone is about five minutes.
I used to be punished once a week with soap, because I wouldn't address him properly or I used the word okay all of the time, when answering a question.
We don't use soap anymore, but I'm sure if he remembered it, he would use it again for some minor infraction, or just because he felt like being evil.
