Is there a way to make a mother-son incest story plausible?

[y=mx+b]

I would imagine if mother and son were watching this happen one or both would start to touch the other in some way. Maybe mum wants to make sure her son is not feeling unhappy and so offers some hand relief? Maybe that encourages the son to touch mum somewhere. Maybe they just share a kiss that unleashes hidden feelings and they leave father and DIL to it while they go and explore themselves. I think we fool ourselves if we think that formal relationships always get in the way of lust/need/desire. It gets in the way of taking action on those feelings of course. NO EMALS or PMs.

Or maybe the father and Daughter-in-law invite the mother to join them. Unsure, the mom hesitantly looks over to her son who gives her the okay.

He watches his mom walk towards his father and wife. His wife on her knees blowing his dad, stops... She looks over to her husband while jacking his dad's hard cock, then looks up to his mom...

Both Mom and dad are looking down at their daughter-in-law who begins switching her attention to her mother-in-law...

The son sits alone watching his wife wondering what and how all this is happening as she begins to slide his mothers skirt upwards.

Lost, the mom closes her eyes as the father grabs hold of her clothed breast and begins passionately kissing her. Reflexively the mom raises her thigh up exposing her full self to her son and daughter-in-law. She hadn't planned it. She hadn't thought it... she just did it and her daughter-in-law wastes no time closing her mouth upon the bare crotch of her mother-in-law...

First issue is...define plausible. Plausible to the OP may make my eyes role, and likewise my idea of it could make someone say 'Oh, come on."

So, there's that.

No matter how real of a concept you try and set up, there comes a moment when the story needs to cross the line into porn absurdity for anything to happen, because "real" dictates that in no way would a mother ever sleep with their son, so we need to be a bit fluid with realism.

I'll give you two ideas I've used

1- father has passed on, Mom has her 20 year old son who is in college and working as much as he can to help. There's also 12 year old twins to worry about. Money is tight, she's desperate. She reluctantly approaches her brother in law who she avoided because he's not only a porn producer, but tried to offer her husband money to sleep with her when he was drunk once.

She goes to him for the money and he offers her what she needs and not as a lone, its hers. If she'll have sex with her son in front of him because he lusted for his own mother years ago, but never had her.

2-A divorced woman decides to partake in a reenactment of a sex game her and some friends played while back in college where they were each in a dark room, and a member of a fraternity entered, had sex with them and left, and they never knew who it was. They do it again, and the woman running it has someone send over fraternity guys so its cougar cub action, the mother goes through with the game, then realizes...of course it was her son...now what does she do?

Far fetched? A bit, but the trick is, can you make the reader believe it?

Both stories have been very successful here.

I read the sex game story. It was great.

I like the mother leaves the family. It's dad, a daughter, just turned 18, and a 3 year old.

The 18 year old quickly takes over the role of mom to the toddler. As she becomes more motherly, she realizes she likes it. She begins to take over more motherly tasks, and dad notices. One night, she decides she wants to be seen more womanly to her dad. He takes the hint and starts to treat her more like a woman.

Eventually, one night, passion takes over.
She takes over the mother/wife role 100%.

Great ideas

A 16-yr old is pregnant out of wedlock, & to avoid scandal she's sent to live with a relative until delivery. Her older sister asks if she can pretend to be the mother, to raise the baby & save the family from scandal. The boy grows to adult hood, & develops a lustful crush on his beautiful 34-yr- old 'aunt', & she feels an overpowering need to give him the warmth & intimacy she was denied to give him by circumstances, whatever form that may take!

How about if it was accidental sex. Say the mother has a son when she was 15 and gave him up for adoption. Twenty five years later they both end up working for the same company and begin to flirt. One thing leads to another, sex ensues. Only after several encounters do they discuss their history and realize they are mother and son. What happens after that? The story can go several ways. They continue their sexual relationship, they are both repulsed by what they have done, or they form a normal mother/son relationship.

In my opinion, it doesn't need to be complicated. It just needs to be a slow burn. None of this rushing in and having sex sort of thing. Most of the incest stories that I read AND enjoy are at least four Lit pages long and the first two are build up. There is angst, a should I or shouldn't I, sort of thing.
