(Sorry for the long intro, but maybe it helps understand some facets of the story)
I have read hundreds of stories on Literotica, and I've written a few dozen, most later deleted. My interest and focus is typically on the "Loving Wives" category, particularly Stag and Vixen stories. I wish there was a separate Stag-and-Vixen category! It is kind of a particular, specific genre--one that does not coincide with so many of the stories in the "Loving Wives" category.
Vixens are the quintessential Loving Wives! They're not cheaters, sluts, whores, or cum dumpsters. They are truly loving wives who have a loving husband who allows them wider boundaries than most wives. They're not necessarily looking for cock, but for lovers they connect with.
I stumbled onto Stag-and-Vixen porn (S&V) by accident, and was immediately fascinated and turned on. I had seldom had any interest in, or fantasies of sharing my wife, and she was strictly monogamous. Suddenly, I was sprouting hard-ons envisioning my wife stepping out of her closed shell and letting her truly strong sexual drive out more, with other men she was very much attracted to, had a chemistry with, and strongly desired physically. I knew she had such men that she was attracted to, but she would not act on her feelings and desires.
In S&V relationships:
The Stag (husband) offers to allow his wife to become a Vixen, i.e., a married woman with the freedom to have sex with other men (and/or women) with her husband's full knowledge and consent and advance approval, subject to conditions, restrictions, limitations, and boundaries they agree on. He may watch, may join in a MFM threesome (no bisexuality) with the lover and his own wife, or he may allow her to go on romantic/sex dates with her lover (perhaps even overnight or over a weekend). He will generally not have sex with other women, but--if he does, it will be with his Vixen's consent and will be subject to the same rules and procedures and boundaries as those that apply to the Vixen.
Or the wife may initiate things with a request for such an arrangement. She may do so because she has an opportunity to cheat and wants the extramarital lover, but does not want to go behind her husband's back. In the arrangements requested by the wife, it seems a little more common that she encourages her husband to enjoy sexual relations with other women, maybe because she feels the need for a quid pro quo or balance. Stags, however, generally don't offer the Vixen lifestyle as a means to have sex with other women.
Or "hall passes" may be granted to the wife on a specific case-by-case basis (e.g., "I'll give you a hall pass to fuck that co-worker who's been chatting you up and hitting on you for weeks").
The Stag husband and Vixen wife still share an active, satisfying sex life together, and the wife's outside sexual activity as a Vixen is only an occasional thing, a special treat to be enjoyed only with men (or women) she is particular drawn to, has strong chemistry with, has a strong attraction to, and with whom she really wants to enjoy a physical, sexual relationship. She is not just looking for someone else to fuck her. She does not have sex with every man she feels attracted to or likes.
After her sexual interludes, she may share details or even pictures or video of her encounter if the husband was not present with her during it. Sometimes, he might listen on the phone during the encounter.
If he watches, it is because he wants to, she wants him to, and because watching her experience her pleasure, fulfill her fantasies, and to see her letting go to truly enjoy them gives him great pleasure through an effect called "compersion."
Some wives love to be watched. Some hate it. Some are intimidated by it. Some restrain themselves if watched, so as not to offend, embarrass, or humiliate their husbands. The husbands who offer this arrangement to their wives want to see them enjoying sex with their lovers fully by being open and honest and relaxed, experiencing the excitement of a new lover, the joy of being seduced and strongly desired, the pleasure of great, unrestrained sex given and received, and the security of a loving, honest, open, no-secrets, supportive, no-humiliation, no-domination marriage relationship with their true love, their husbands.
Many couples describe experiencing an overwhelming bonding and team feeling when he watches her having sex with her lover. Husbands who watch often kiss their wives or hold their hand as she experiences sex with the lover, or they may assist in some manner. Most say it makes them feel closer and connected, and that it enhances the experience--and even their relationship.
If the husband joins in sexually, it is because she wants him to and he wants to, giving her double the sex, and being intimately involved in even the extramarital sexual relationships that the wife is allowed to enjoy arouses him. In many couples, watching often leads to joining in, particularly for active watchers who kiss, hold hands, and assist.
If the husband allows the wife to have dates, overnights, or weekends with her lovers, it may be because she can't fully relax and enjoy everything with him there, watching, listening, or joining in. Or, it may be because he cannot take the intensity and confusing feelings that sometimes become overwhelming in such situations.
Or, it may be that a much-desired lover can't relax and accomplish the purposes for which he (or she) is there with an audience present. With repeat encounters with a known and trusted lover, the husband may simply allow them the privacy to enjoy themselves together, content to hear all about it from the wife later, trusting her and knowing she's coming home to him.
Most Stags in these relationships want to know who and when she's fucking, and where, before she does it, primarily for her safety and his own peace of mind; it also provides a sense of security for the Vixens. Most Stags want to be there. Most like to be involved in vetting and approving prospective "stranger" lovers for the Vixen (as opposed to friends and colleagues). Since the arrangement is based on a strong, loving, trusting, secure relationship, many husbands eventually give their wives nonspecific, permanent "hall passes" to fuck whoever they want, whenever they want, in a "fuck first, tell later" arrangement. Most Vixens are too satisfied in the marriage, with their husband, and with the freedom to fuck that he grants her, to abuse that trust.
The S&V relationship is about the spouses' marriage and relationship, and is built in mutual trust, respect, integrity, and honesty. Consequently it is about both spouses, husband and wife, and the pleasure she receives directly--and the vicarious pleasure he receives from witnessing her pleasure, arousal, excitement, sexiness, abandon, and the intense mix of arousal, concern, nervousness, jealousy, and awe.
If he watches, his voyeuristic interests are fed (he thinks she's incredibly sexy when she fucks, but he's probably never had the amazing views that watching affords him). If she talks to him as she fucks her lover, he is reassured and aroused by her affirmations that she's loving it and is turned on by knowing he is happy for her and is turned on by it all, and by her particularly. If she fucks without him present, any pictures, videos, details, descriptions, stories, and "evidence," coupled with her excitement and gratitude feeds the same or similar interests.
Stags are strong, confident men who sexually engage with and please their wives frequently. They love and trust and respect their wives and want the best for them.
Vixens only occasionally have sex with other men or women, and must be inspired and strongly attracted to do so. Vixens are looking for real chemistry and connection--and great sex; they will not be seduced merely by a big cock or much else if chemistry and connection are not there.
Stags will not tolerate being humiliated, embarrassed, disparaged, taunted, or treated as less than her lovers (Almost all Vixens will quickly show lovers the door and they will never get another chance with her if they do those things). That may be part of the Hotwife- Cuckold relationship, but it has no part in a S&V relationship.

These things are what I discussed with my wife over many conversations over several years after offering her a Vixen lifestyle.
Unfortunately, when she tried to research it, all she ran into were essentially disgusting (to us) "sissy cuckold" Hotwife porn, filled with weak, gay and bisexual men posing as straight husbands, and the "cuckold" and humiliation varieties that are also quite disgusting to masculine men and the strong wives who love them.
After seeing what she thought was S&V porn, pics, memes, and stories, she quickly told me, "Oh hell no!" She wouldn't even discuss it further after that. Since then, I've occasionally intentionally left online S&V blogs and websites open on our computer, or left magazine articles where she would see them. She has never said anything about any of them. At times, I have suspected that she has read or viewed them, though.

Then, one evening when I was away from home for three weeks, my wife texted me:
Her: I found and read your Literotica stories today.
Me: (picture of a scared wide-eyed little boy, then a pic of a boy looking ashamed, then a pic of a doghouse. For good measure, I sent a link to the old Hank Williams' Sr.'s old song, "Move It On Over." to illustrate I knew I was in the "doghouse")
