What is the ruling on a husband asking his wife to kiss his private parts and body, and to place her vagina on his backside and move back and forth until both of them ejaculate, during her menstrual period?

The majority of scholars hold that it is impermissible to enjoy intimacy with a menstruating woman between the navel and the knee, contrary to the Hanbalis, who permit it. What is above the navel and below the knee is permissible by text and consensus, while vaginal intercourse is forbidden by both. Some scholars have gone as far as to prohibit a menstruating woman from allowing her husband to enjoy intimacy between her navel and her knee; therefore, it is more cautious to avoid that. Vaginal intercourse with a menstruating woman is a major sin.
