Did anyone receive a spanking after a panties or underwear inspection.

Many a time my mom will give me a surprise panties inspection and if it is soil a spanking will follow. She said that girl must always keep their underwear clean.

I try to wipe my bottom clean with toilet paper but however I wipe I miss some spots and my panties is soiled. During my younger days all my panties is white so it is easily seen when it is soil with yellow or brown stain.

Any type of stain on the panties warrant a spanking session

Any suggestions of keeping a clean white panties to avoid the spanking?
