Aunt Amy stands naked in the doorway of the bedroom and finds Wendy and Denise with their heads resting on Robert's chest. "Good morning, sleepy heads!" she chimes out.

Wendy looks up to her sister-in-law with a knowing look. Robert and Wendy's daughter sit up a little but give a more wary and groggy, "good morning, Amy."

"I got Sam and Ginny to agree to a swap. Robert, Denise, would it be alright if Wendy went over to her son's room and join them over there? I'll just slide in with you two over here."

Record screech, how did we get here?

This world is much like our own, but men tend to die around 40 while women live to be older, like in our world. I know that this isn't what "black widow" refers to, but it makes for a snappy title. Anyway, there's a natural unbalance between men and women in this world. It's normal for a younger man, a younger woman, and older woman to form a romantic triad. Other pairings are also perfectly normal and accepted, but it turns out that these MFF triads are just as common in this world as MF couples are in our own.

In fact, it's not uncommon for the older woman to be the mother of either the primary wife or of the husband. Again, certainly not in every case, but it eliminates the need for anyone to go through the whole dating process a second time. Besides, familial bonds can be quite strong. Strong precautions are taken against pregnancy of the older woman in most cases, especially if she is related to either of the younger two. The younger two are almost never related to each other, just like in our world.

Their private lives range from the older woman having her own bedroom with occasional "visits" to fully-participatory incestuous threesomes. Private lives are, indeed, kept mostly private, and any children involved are shielded from the sex lives of the adults in their families, just like in our world.

Here are the characters (maybe a bit morbid in spots, but we'll move past that soon):

[Dad] - the central character in the beginning, around 40. Unfortunately, he dies soon.

[Wife Wendy] - the primary wife of Dad, soon to be Widow Wendy.

[Mother of Dad] - the secondary wife, also, unfortunately soon to die.

[Daughter Denise] - the youngest child of Dad and Wendy, living away from home in her second year of college.

[Son Samuel] - Sam, a couple of years older than Denise, also away in college

[Brother/Uncle] - of Dad/Denise and Sam, soon to be dead

[Aunt Amy] - primary wife of Brother/Uncle, the only one so far not related to anyone else

[Mother of Amy, Mary Angela if you need a name] - secondary wife of Brother/Uncle, soon, you guessed it, dead

Brother/Uncle and Aunt Amy didn't have children

[Boyfriend Robert] - of Denise, hates being called Bob

[Girlfriend Ginny] - of Sam

So, you can see, it was quite normal for Denise and Sam to grow up in a household with such family triads.

Last Thanksgiving had the first eight characters, as usual. There was a growing elephant in the room that, maybe soon, Wendy and Amy would be pairing up with Denise and Sam in some way, but no one ever talks about it. Then, indeed, shortly after the holidays, tragedy strikes the family. Dad, Dad's mom, Dad's brother, and Mary Angela pass away fairly close to each other. Yes, it's sad, but not unexpected, and we need to move the story along to this year's Thanksgiving dinner quickly so that we don't have to worry about mourning and all these damned extra characters.

This year, Denise brings home Robert, and Sam brings home Ginny. Wendy and Amy are there, too. They are moved on from their husbands, horny, and excited that there will be two eligible men in the house. They both try to hide it, though. Even though they are sisters-in-law, they are not competitive and hope that it will all work out. Maybe they even plan a swap for the morning after.

Robert and Ginny know the family history, but even Denise and Sam don't know how this is going to play out. It's pretty well understood that everyone will break off into triads after dinner, though.

Robert is most excited about it. Denise knows that he casually dated a couple of older women. Denise and Robert had a couple of casual threesomes with her college girlfriends, but she hasn't been with an older woman, yet. Sam and Ginny are a bit more ambivalent. They don't resist the idea at all, however, and Sam does want to emulate his father and have his secondary older wife, whoever it might be. Ginny hasn't been with a woman before, but she's ready to support her husband in any way that's needed. They might need some coaxing to make it all work smoothly.

To keep things simple, everyone has the same limits of animals, blood, and bathroom stuff. Different characters may very well have different kinks based on our ideas. We don't have to follow all six characters in a role play, but we can follow a few of their stories. The swap on Friday morning is totally optional.

Reply with an idea of what character(s) you might like to play, where you might like to start the story, and any ideas that you have about the setup and/or where it's going. It will almost have to be long term.
