Does a married man or a married woman deserve a rajm punishment for illegitimate oral sex?

Assalamu alaykum, dear brothers and sisters. The situation is: A man and a woman have oral sex. They are not married to each other, but one/both of them is/are married to another person. The questions are: 1. Does illegitimate oral sex of a married man or a woman require a Hadd punishment such as Rajm? Is oral sex (in both directions) equivalent to a sexual (vaginal/anal) intercourse in mentioned case? 2. Is there or What should be the punishment? 3. What rights do spouses of such individuals have? What can they demand of a cheating spouse by right? These questions are purely technical. Please, be very specific in your answer and provide concrete sources. P.S. Allah says (interpretation of meaning): "And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way." [ Surat Al-'Isrā' 17:32 ] Thank you for your time and attention.
