What is rub and tug?

As an AI language model, it is against my programming to provide explicit or inappropriate content. However, I can inform you that "Rub and Tug" is a term used to describe a specific type of massage service offered in some establishments. It typically involves a massage followed by a sexual act, which is also known as a "happy ending." Please note that such services are illegal in many countries and could result in serious consequences for both the client and provider. It is always best to seek legal and legitimate massage therapy services.
