Mom's Twin helps get Mom.

[Wincester]

Alright, so this is a little idea I've had swimming around in my head for a while, in case anyone wants to adapt it.

Son has grown up with a serious attraction to his mother, but she's never really been TOO aware of it. Maybe she's noticed him stare, but just chalked it up to teenage hormones. Meanwhile, her twin sister, his aunt, has been feeling a bit unfulfilled with how her usual cougar stud-hunts go, and wants to find one she can trust to be a more… permanent partner. Noticing her nephew's stares to his mom, she hatches an idea.

One night at a (costume/halloween) party, she brings a second costume with her, identical to the one her sister is wearing, as she learned when they went shopping together. Changing part way through the party, she tricks her nephew to get him alone. Ideas I had for this part were
- Pretend the bathroom door is jammed and then slip inside with him
- Tease him in the costume, then barge in when he goes to relieve himself
- She could say she needs help adjusting her costume, but wants to do it in private in case of a wardrobe malfunction

After getting him alone, she seduces him playing the part of his mother, and gives him one hell of a time. Playing with her tits, sucking him off, pussy, anal, maybe even some toys, bondage, etc.

She reveals the truth afterwards, and offers him a deal: If he agrees to become her new fuck-buddy, she'll help him to get his real mother. From that point forward, she helps him set up various situations to tease her until the big moment comes (I'll leave that moment to anyone who picks the idea up.)
- She talks up his figure at the pool/beach
- Son follows mom while she goes for a run, she realizes he's staring more
- Aunt just has a talk with her sister to make sure sex is on her mind, her son being the closest male.
Stuff like this

So yeah, idea's a bit long, would probably take more than one part, but just thought I'd put it out there for anyone interested.

Interesting idea, and I agree that it'll probably work best with more than one chapter. The first chapter could be the son & aunt having sex.

I think the second chapter could be the two sisters having a private talk by the pool. The aunt switches the conversation to their love lives. The aunt then talks about the benefits of sleeping with a younger man, and that it's emotionally fulfilling to be lusted after a young man. The mom is intrigued by the idea, but laughs it off. It's not for her. Especially since she doesn't want to ruin her reputation because she's a teacher or professor.

Maybe later that night she fantasies about it.

Days later, the mom admits to the aunt that she was excited by the idea. The aunt smiles, and details her sexual exploration with her younger man, describing the sex with her son, but of course the aunt doesn't say it's the son.

The aunt then suggests to the mom that she should sleep with her own son, since it will be in the house and no one will know. The mom laughs it off and is shocked. But the seeds have been planted in her mind...

If you wanna tweak it, the twins have been active with each other since... Well a very long time. Aunt is aware sis has a thing for son, then discovers, through what you put, that the son has a similar desire.

She plays both against each other, neither mom or son knowing she's helping the other... Until it all boils over and mom & son end up fucking hard and fast, then discovering the other woman's role... They team up and take her on...

The Aunt could tell her sister that she caught him sniffing her used panties and got flattered about it since she knows boys like to sniff panties.

Then ask her sister if she will also get flattered if her son sniffs her used panties.

Then The Aunt tells her nephew to let his mom catch him sniffing her used panties.

Reverse.

The Mother wants the son, but feels it would be sick. Her twin sister comes to stay and he notices the son staring at the aunt as well.

Mom seduces the son as her sister. This way she is fucking her son, but he doesn't know it. He thinks he is doing his aunt and is told of course to keep it quiet and never mention it. She will decided when and where so that way the aunt stays in the dark.

Then of course the aunt ends up catching them. From there she could catch on and pretend to be mom or....It could have some good twists and even some comic overtones

Interesting variation that I never thought of myself. Also, may I just say, love your works.

Well thank you! Good to know someone does.

If I can add something from an earlier idea (the twins are already active together), maybe after the first pair is established and the seeds planted in the other woman, she's tied up and presented to son as a present.

Your bondage-incest stories are pretty good, from "Mom is Bound to Please," and the idea as a whole has peaked my interest since.
