Incest: brothers’ girlfriend helps sister to secretly have sex with him

[i12b3]

This is a story idea for which I would love to read a story about but my writing skills are not good plus English is not my native language.

Genre is definitely incest and it’s all about inventive ways to get the sister involved in sexual activities with her brother without him knowing (although other storylines could be interesting as well!)

Let’s say, the girlfriend has sex with her brother and because she can hear them, which is why she gets turned up about her brother more and more. Or naybe she starts spying on them. There’s enough room for other ideas here.

Somehow the girlfriend and the sister are getting involved with each other first. For instance, after the GF had sex with her brother they run into

I explored a similar theme in my "Craving Daddy's Cock" story. A daughter wanted desperately to have sex with her father, and she enlisted the help of her best friend. They tried various schemes, but kept having difficulty until... well, no spoilers!

Which I just read today, which remind me of my own story idea I have for a long time. Your story was hot though! I also checked out your other stories. Again, they are hot. My compliments!!

I do like the story idea and remember a porn vid I had watched along such a story line - the gf blindfold the brother and then switched places with the sister.

I can imagine some other ways the brother gets seduced into the idea.

- gf and sister are good friends and plot to get him to fuck his sister - the gf keeps getting more and more bold when the three of them are together, watching a movie, or whatever. At first the guy is of course shy with his sister right there, but each time the gf pushes the envelop further and further. Soon they are having sex while the sister watches and masturbates. Soon they enjoy a full fledged threesome

- gf and sister don't get along, the sis constantly telling her brother he can do so much better. She plots to get her out of his life:
- has another guy seduce the gf so the brother is crushed and she comforts him, one thing leading to the next
- she finds a way to get her to leave as she and the brother are making out (an emergency text or something), leaving the brother with blue balls and the sister, wearing a skimpy negligee comforts him as his horniness keeps rising

So many good ideas. I like them all!
I’m also thinking about additional storylines like the GF is fucking their father too.

I have vague memories of a story where a girl entered into a family, I forget how, and basically broke down all the barriers. By the time she left, they were all happily fucking one another...

Plot bunny: Ultra-religious grandpapa wills his vast fortune to descendants who remain "morally pure". A devious relative hires a gal to seduce all other kinfolk and incite incest. Follow the money.

There are a few stories about freaky girlfriends who find a way to get their boyfriend and boyfriend's sister together. An interesting angle might be to have the sister and girlfriend talk and realize they are both a couple of freaks. Have them team up.

Billy has been cheating on his supposed steady girlfriend Ginny. Her supposed besty Betty (she's Billy's sister) knows but hasn't told Ginny who vows revenge on the siblings. Ginny applies persuasion and chemicals to get everyone naked in bed. (Yes, all are over 18.) Ginny easily leads Betty between her brother's legs where they both blow him. Ginny then maneuvers Betty to cowgirl-ride her brother's cock... while Ginny takes photos. Now she has blackmail and/or punishment material. Revenge is sweeter than sugar.
