I'm not usually big on Mom/son or brother/sister but what if there was a brother and sister into incest. One night, Mom passes out on sister's bed. Son crawls in expecting sister sex....
 
Yeah.

I think if you want to play with a mix up, costumes AND a dark room are the way to go.

Family is throwing a party and as things die down, bro feels a message being slid into his pocket. It’s from sis saying “downstairs-half an hour, keep the lights off and lock the door”

He goes to the downstairs guest room. The little bit of light he lets in before closing the door shows a tights clad buttocks positioned up in the air. Sis and mom were both wearing tights but in his eagerness he closes the door before checking if they were the same style, he yanks the tights down, eats her out for a bit (mom also waxed) and then fucks her hard, only finding out about the switch when she starts whimpering and calling out his dad’s name.

Meanwhile sis is downstairs, ass up in the darkened game room, bent over the couch, no idea dad got a letter from mom telling him to come downstairs, kept quiet and to keep the lights off
 
Simple scenario, son sees Mom at the sink and mistakes her for his sister. Something about her hair or the way she's dressed. He comes up behind and puts his arms around her. 'I sure would like to fuck that ass,' he says grinding his stiff one against her for emphasis.

Mom spins around, outraged. 'What the hell are you doing?' Son backs the hell off, 'Shit, sorry mom. Thought you were someone else.' 'Who? Who did you think I was?' Son flees the room.

Then begins a game of cat and mouse, with mother trying to catch her children having relations and not entirely sure what will happen if she does.

I like this, but in my minds eye I see him mistaking his mother-in-law for his wife.
"Damn, babe, that ass is looking good." he says and takes her hips in his hands, grinding his crotch against her ass. "Do you think, we can have some fun tonight?"

She grins and lets him grind away for a while before replying. "Sounds good to me, if you don't think my daughter would mind."

Absolutely, applicable in many situations. But in that case he could say he thought she was his wife.

If mother and sister are the only women in the house, who did he think she was? There's your tension.

There was a TV commercial back in the sixties, I think it was for Grape Nuts. Pool party, everybody splashing around, and the boyfriend mistakes his girlfriend's mother for the GF. I don't remember what he does, but it wasn't too naughty. Implication of course is that eating Grape Nuts makes you look a full generation younger.

I always laugh at the innuendo of "Grape Nuts". I must be very juvenile.
 
Alex was a horny young football jock who would fuck anything that moved. He had always had an interest in older women and had a string of the towns more influential women willing to reward him for his attentions.

This didn’t stop him from chasing younger tail also and his book of sexual conquests grew by the month. The one conquest that was not in his black book was his twin sister, they had always been close and as they matured this became a sexual relationship that though taboo they both wanted and enjoyed, maybe because it was taboo made it more exciting than all the others.

The idea was to take all the aspects of your post and bind them into one story. Older women, brother/ sister, mother and son by mistake. But the outline got cropped and I did not copy it before posting.

How about this...

Jack and his sister Jill used to play naughty together. Nothing really bad, just practicing kissing and maybe a little heavy petting.

A few years later and Jill is home from college for the summer, and Jack wants to see if she would be interested in taking their play to the next level.

Meanwhile, Jack's mom has had a quarrel with Jack's father and is sleeping in Jill's room while Jill is out with friends.

Of course Jack thinks it's his sister when he sneaks into Jill's room and crawls in bed. And of course he needs to keep things quiet they won't wake up mom and dad.

Jack's mom thinks it's her husband coming to make up for what he said/did, and responds to Jack's advances in ways he never expected. She is also staying quiet to keep from waking Jack.

Jack ends up taking his mother from behind as he caresses her breasts. They end up coming together, and Jack slinks off to his own room thinking he fucked his sister.

Jack's mom goes back to her own bed pleased that her husband gave in and made up in the way she had always dreamed he would.

...So the story would go on to tell how it all unravels, how the characters feel about it all, and what they each do about it.

do they discover the mistake?
 
Jill and Joan were twins and were always close from there first nappy change till the current day. As they came of age boys passed them around like pieces of meet to fuck and discard.
This gradually pushed them closer and closer together until they finally made love to each other making each other orgasm more than any young buck could ever do.
After a few months of this they decided to get their own back on the boys that treated them so badly in the past by inviting them over and fed them so much sindafel that there cock would not go down and they fuced each of them to exhaustion or worse.

Just an idea kf
