When Oedipal/Incestuous sex is found out by others?

[PaulScottBarbarasSon]

A sister walks into the house one day and discovers her brother having his cock sucked by their enthusiastic mother.
A brother comes home and finds his sister going down on mom and making her cum.
Brother and sister discover that their mother and aunt (mom's sister) have a sapphic relationship.
The neighbor lady inadvertently walks into the house one afternoon and finds the neighbor mom having an orgy with her son and daughter.
And there are any number of other combinations. To my own taste, I always prefer older female relatives (moms, aunts ) mixing it up with younger male, as well as female, relatives ( sons, daughters, nephews, nieces ). My imaginary settings are otherwise respectable upper middle class communities and the characters otherwise respectable types. I prefer buxom females. But that is me.
I am not interested in the discoverer falling into bed with the discoverees. At least not right away. That is too much of a porn cliche.
But what would be a realistic, but entertaining story of incestuous sex being found out? Especially in a respectable family on Maple Street, USA?

How about a woman stops over for an unannounced visit and walks in on her sister sucking her son's prodigious cock. She just stands there in shock for what seems like an eternity until her nephew realizes that they are not alone.

The freaked out woman runs back out to her car and drives off. She ignores her cellphone as she is repeatedly called by her sister. The scene replays over and over in her head. She doesn't know what to think but she can't get over how large her nephew's cock is.

Eventually the sister shows up at her house to try to explain herself. The loneliness after her husband left, it just sort of happened, etc.

Over the next month, the woman has dreams of the scene that she witnessed. The scene changes after a week where she is sucking her nephew's cock. The scene changes again where she is sucking one of her twin son's cock. She disturbed by the escalation of her dreams. Eventually she's fucking both twins and her nephew in her dreams and drenching her sheets when she wakes up.

She starts looking at her sons differently. She notices the pronounced bulge in their pants. She has all of these new sexually pent-up desires that she doesn't know what to do with. The woman talks to her sister about it and the sister tells her that she was in the exact same spot that she is currently in. Eventually her desires overcame the incestuous taboo and she realized that she had no regrets afterwards.

The woman goes home and seduces her twins. Eventually they are all fucking everyone else.

That's along the lines of an e-book I put out this year.

A divorced woman who has a twenty year old son let her best friend, who is now also divorced and trying to get her life started again stay with her and she also has a son a year younger than hers.

The woman comes home early from work and as she walks past the window of the room her friend is staying in she hears moans and the sounds of sex. Thinking her friend has a guy over she decides to peek into the window and sees her friend fucking her own son...

As your description goes she is appalled, the friend saw her in the window and tries to explain and in the conversation says deep down all sons desire their mom and it doesn't take much to get that to the service. The woman then starts dreaming of her son hearing her friend telling her how hot it is and starts dressing adn acting differently seeing if her son seems to notice and he does and....well you know

As part of the back story I mention the mom and her friend had wild times when they were younger even sharing the same guy a couple of times and I'm Thinking of a follow up where they fuck their son's in front of each other and maybe they swap off....
