bisexual adult incest idea

[donaldelliott11]

I'd love someone to write a story about two married sisters. One is slightly bossy, has always dominated the other sibling. Nothing sexual, just a typical "bossy big sister". Big sis has an open marriage, and she and her husband play around a little bit.
Little sis thinks her husband might be cheating. Does a little snooping, and to her horror discovers he's bi and has a series of 1-night stands with on-line hook-ups. All his cheating is with dudes.
Mortified. little sis tells her sibling that she thinks she has to divorce. Big sis counsels patience and further study. When she tells her husband, he sets up a Tinder profile to snare his brother-in-law. He coerces sex from the bi husband "to keep quiet". Meanwhile, with his bossy wife's help, he seduces the little sister. Denouement is toppy couple having an orgy with mousey sister and her bi husband.

Just to ramp up the squick factor, make the two husbands brothers as well.

Interesting idea, although I would make a slight change if I were writing it. I would have little sister start suspecting that her husband may be cheating on her. She talks with her older sister and tells her that she's afraid to dig deeper because of what she might find. She's worried that she'll have to file for divorce if she finds out that he is cheating, and the thought of that is too stressful to deal with. Older sister already knows that he is fucking around, because he has been her husband's bi-sexual lover for some time, but she doesn't tell little sis just yet.

Older sister calms younger sister and steers her away from the divorce talk by telling her that she'll get her husband to talk to younger sisters husband and see what he can find out. Older sister's husband is the dominant in the relationship with younger sister's husband, and older sister starts eyeing her own younger sister as a potential submissive for her. Of course she'll need the help of her husband to seduce her own sister. What kind of plan does she have up her sleeve to turn her mousy little sister into a submissive slut for her pleasure?
