Doing skype sessions with a Mistress, she had me apply toothpaste to my cock and balls. I have no idea why, just one more thing to wash off after the session, which includes teasing, panties and spanking. What is the toothpaste for> ?
Peppermint or Spearmint toothpaste when used on the private bits of women cause a burning sensation. I would assume she thought it would do the same to a male.
