You are not the first to present this scenario on this forum. Plural marriage is not part of the Church at this time, at least not for mortal people, so the question is currently moot (of little or no practical value or meaning; purely academic).
The Family: A Proclamation answers your question though. I'm aware that most posters on this forum do not believe in the validity of the LDS Church or the Brethren, and if you're one of them, it's doubtful you'll care what the Proclamation says - but on the outside chance you do give it any credence, these excerpts answer your question -
"We further declare that God has commanded that the sacred powers of procreation are to be employed only between man and woman, lawfully wedded as husband and wife."
In a plural marriage, the wife is wedded to the husband. Two wives are not wedded to each other. They are all separate marriages, therefore, two or more wives in a plural marriage should not be sexually active with each other, whether their husband is present or not.
Also -
"We warn that individuals who violate covenants of chastity, who abuse spouse or offspring, or who fail to fulfill family responsibilities will one day stand accountable before God."
Again, there is no configuration of women having sexual relations with each other that does not violate the covenants/law of chastity. Just like there is no configuration of men having sexual relations with each other that does not violate the covenants/law of chastity.
Also, from
Gospel Principles -
"God has commanded us that only in marriage between a man and a woman are we to have sexual relations. This commandment is called the law of chastity. We are to have sexual relations only with our spouse to whom we are legally married. No one, male or female, is to have sexual relations before marriage. After marriage, sexual relations are permitted only with our spouse."
"Like other violations of the law of chastity, homosexual behavior is a serious sin. Latter-day prophets have spoken about the dangers of homosexual behavior and about the Church’s concern for people who may have such inclinations. President Gordon B. Hinckley said:
“In the first place, we believe that marriage between a man and a woman is ordained of God. We believe that marriage may be eternal through exercise of the power of the everlasting priesthood in the house of the Lord.
“People inquire about our position on those who consider themselves so-called gays and lesbians. My response is that we love them as sons and daughters of God. They may have certain inclinations which are powerful and which may be difficult to control. Most people have inclinations of one kind or another at various times. If they do not act upon these inclinations, then they can go forward as do all other members of the Church. If they violate the law of chastity and the moral standards of the Church, then they are subject to the discipline of the Church, just as others are.
“We want to help these people, to strengthen them, to assist them with their problems and to help them with their difficulties. But we cannot stand idle if they indulge in immoral activity, if they try to uphold and defend and live in a so-called same-sex marriage situation. To permit such would be to make light of the very serious and sacred foundation of God-sanctioned marriage and its very purpose, the rearing of families” (in Conference Report, Oct. 1998, 91; or Ensign, Nov. 1998, 71)."
Women having sexual relations together, in any configuration, is violating the covenants and laws of chastity. Women in a plural marriage, are NOT married to each other - they are each, individually and separately, married to the man. It is not a "group" marriage. There is no sanctioned "group sex". Is this really a question in some members minds?
