sibling incest non consent with a twist

[siblingman]

I have the general outline for a story but need as much input as you guys can give me (male & female aspects). It involves a guy who grew up with 6 sisters. He loves the idea of incest, has fantasized about it, but never participated.
He's brought up the idea of incest in role playing with his girlfriend (in her 30's but can be any age) but she is totally against the idea. She has a brother 2 years older and a sister 5 years younger.
The girlfriend invites the brother & sister over to her house for a night of partying and they are going to stay overnight. The guy thinks that this may be his one & only time to witness incest and starts to plan how to make it happen.
Now for your suggestions...drugs or alcohol can be used. And in my outline, the brother ends up having sex with the younger sister first, then his girlfriend right after.
They can be aware or not aware of what's going on. But when they wake up in the morning, no one realizes what happened.
The boyfriend is directing the entire scenerio and videotaping everything for himself. That's the basics...your suggestions please???

Sounds like a pretty well developed plot scenario.

Alcohol and drugs are a bit boring in terms of adding to the eroticism- people in a stupor aren't that sexy. You could try blackmail of the younger sister, a semi-forced scenario with ropes and the whole bit.

But if the younger sister is blacmailed in some way, she would be aware the next morning of what happened. My idea was for sex to occur but no one would remember what happened the next morning. That's why I thought alcohol or some sort of drug would help.
If you can tie the blacmail angle in, that would be great.

Oh, so no memory of it is important?

Well you could just cull them afterwards. That would be new and exciting.

What a delightful fuck, says I.

I must make sure that no one remembers. Where on earth did I put my club?

Oh, here it is silly me! One for you *Thump*, one for you *thump* and one for you *thump*

I don't think its been done on Lit. IT would be just like with baby seals except less traumatic.

I think Athena is right in that alcohol & drugs to induce what is effectively rape is somehow too easy to come up with, and done so many times before. (in story form as well as in the yucky old real world, lol!)

Perhaps you could find someone who knows about chemistry to see if this is possible: Throughout the night a chemical is released into the air around the house. I'm thinking like a gas leak or something, though no idea what the effects are. Somehow the chemical induces such behaviour.

I know, just like drugs really. I'll shut up again!

I don't like the seal clubbing idea...but the gas idea has some merits. The gas would make them horny, take away any inhibitions they may have, make them very agreeable to suggestions and then not remember anything in the morning. That could work!!!
But how does the boyfriend not get effected by the gas??? He'll be the one directing the siblings and videotaping.

My first thought was that rather than boyfriend/girlfriend, they're married.

Otherwise, little sister has a bit of a crush on her sister's boyfriend. She flirts with him. Maybe even once as he goes to get snacks from the kitchen, she offers to 'help' him. She does more groping than helping. Back in the living room, she sits on his lap. Work it up some more. Lil' sis asks big sis if she can give her husband a blowjob. "He's got this big boner and it's uncomfortable." "Yeah, right. Go ahead, we'll watch." Big sis and her brother get turned on by watching. Husband suggests to his wife that she take care of her brother, he's just as hard as he is.

Getting the husband to play with little sister is easy. The hard part will be to get his wife and her brother together.

You say that you don't want them to remember anything. Only reason for that I can guess is for part two to include blackmail, giving the guy ammunition for watching more incestual sex.

Perhaps there's another way to get the blackmail ammo. They're out back, having barbeque. Afterwards, they get in the pool. As it gets dark, wife whispers to hubby, "too bad they're here. We could get naked." Hubby makes excuse to go into house and he sets up video camera in a window. When he gets back to the pool, he takes off his swim trunks. "Hey guys? Usually when it gets this dark, Wife and I get naked." Wife says, "it's no big deal. Mom used to bathe us all together." She starts to take off her swimsuit. Not wanting to be prudes, her siblings follow suit. Something (maybe a game of Marco Polo) gets naked bodies closer together. Or, maybe they're playing pool volley ball and when the brother scores, the sister on his team gives him a hug. Nothing sexual happens, but on tape...

Sorry for the rambling, my imagination got the better of me.
