Boyfriend Helps Family Member with Incestous wish

[Strangebuddy]

I had a weird little idea for a Thanksgiving story which I'll share below but since I love hearing other writers' ideas I'll just say the general idea first:

A boyfriend/spouse/fiance is spending time with his girl's family when he discovers that one or more of them is attracted to his girlfriend. While the family member is quick to tell the boyfriend that he/she would never act on it, the boyfriend actually aids them in approaching his girlfriend about it provided that they keep two rules in mind:

1. It has to be consensual
2. He gets to watch/participate

The idea I had was a bit convoluted but I wanted to share it so I could get some feedback. The boyfriend in this case gets invited to go to his girlfriend's (who is more of a fuckbuddy) house and have thanksgiving dinner with her family and spend the weekend before taking her back to college. On the ride there, his girlfriend teases him about how she won't be available to him the whole weekend due to dinner preparations/shopping/visiting the family. The boyfriend then jokes that he'll just have to seduce her 18-year-old sister and the girlfriend just laughs, saying her bookish sister doesn't show an interest in anyone.

As they get closer to the girlfriend's house, she decides to place a wager. While she doesn't want to see her little sister get hurt, she does want to humble her boyfriend a little. If he can get her sister to make out with him on Thanksgiving or Black Friday, the girlfriend promises to stay home on Saturday and let the boyfriend use her however he wants.

The boyfriend takes the wager and immediately starts trying to get closer to his girlfriend's sister. The girl likes the attention but still tries to keep the boyfriend at arms length throughout Thanksgiving, which makes the girlfriend amused to no end. The boyfriend's about to give up when he walks past the sister's room, where he hears her frantically typing. He waits until she slips out of her room and finds out she was working on some erotica. He takes a minute to find her username and then notes that the sister seems to focus on one genre specifically: Incest. More specifically, incest between sisters. Most intriguing of all, one of the sisters always looks like his girlfriend.

The boyfriend waits for the sister to get back and confronts her about her writing, before telling her about the wager and making her an offer she can't possibly resist.

That's actually a genius storyline.

Perhaps the boyfriend and sister work out a plan (which the sister is shy about of course) where they would kiss in a way that makes it look secret, but that the girlfriend gets to see it.

The boyfriend later says, "I told you I could do it" to his girlfriend. The girlfriend is utterly dumbfounded that her sister actually kissed a guy, but she also loves the idea of letting her boyfriend do whatever he wants.

The bf wants to blindfold the girlfriend and admits he has lesbian fantasies. The girlfriend says she's always been curious about other women.

You can imagine the rest...

I have to second that this is a really brilliant idea. The story seems fun, there are enough details that you could run with it and at the same time it's not bogged down with all the crap that you often see in story ideas where you've simply got way too many moving parts going on.

I notice you weren't clear on if you were looking for an author or to write this yourself. I'm always part of the clan that would encourage you to write it yourself (as well as for any author who thinks it's a good idea to do so as well) but you seem to have a quality command of the English language, you're certainly creative enough.

Thank you both very much. Sean, I am hoping to write the idea I posted up but it might take awhile. I just wanted to see what other people thought of my idea as well as see what spins they might take on the basic idea I proposed (I definitely have no problem with anyone who wants to take the idea and make their own version).
