My fiancee and her sister...

Ok, so like I have mentioned before, the cuck thing doesn't do much for me. That being said, it was akinda hot for me the one time that I fucked a girl in front of her boyfriend... he knew that she had been cheating on him with someone (me) and was apparently into that, so it was arranged that we would have sex in front of him. It wasn't as hardcore as some of the things I've seen on this board... for instance, I didn't have him suck me off to get me hard, or clean her out or anything. And to be completely honest, it was kind of an awkward experience for me.

Now, my fiancee has her sister (and her boyfriend) coming into town to visit later this month. I guess her and her boyfriend are very into the cucking lifestyle, and her sister has heard a lot about my sex life with my fiancee. Her sister wants to have a threesome with me and my fiancee while they are in town, while her boyfriend watches. Now, my fiancee is into the idea, as she is the one that told me about it. I'm just not sure what to do.

Has anyone ACTUALLY (bullcuckolds brownieting aside) been in a situation like this? What did you do and how did it turn out? Any insight would be appreciated.

Thanks.

bump... no input whatsoever? I guess I should mention that it is actually a step-sister... but they've been step-sisters since they were like 3, so they think of each other as real sisters.

Well thanks for the input and the honesty. I have been leaning towards not doing it anyway. I just feel weird about it. If it were just a girl I was relaxing with and wanted to bring her sister into the mix whatever. But this is my fiancee... it just doesn't seem right.

And as far as having a crush on her sister... I have only met her once, as she lives across the country, but I found her extremely annoying. And although she is somewhat attractive, she wouldn't stand out in a crowd by any means.

I think you should do it.
