Hi everyone,

My girlfriend has recently expressed a sexual fantasy regarding myself and her sister, and I'd like some advice. There is a lot of detail which is important, so this is a very long post. I've split this post into sections, with the last few days at the end.
I'd like to be very clear that initially this was only my girlfriends fantasy!

Firstly, a little background:

We've been together for just under four years, have a solid relationship, an excellent sex life, we are swingers, and we are very open and honest about things with each other. We are very comfortable together and very happy. Emotionally we are incredibly we suited and we support each other no matter what we might be going through. Sexually, we are incredibly compatible. We totally meet each others desires and expectations. To quote my girlfriend - "We make a great team."

Her sister

My GF and her sister have never really been close, but since me and my GF met that has changed vastly. Myself and her sister have also become very close and comfortable with each other. It took a while at first as she was very shy, but has grown in confidence as we've got to know one another. My GF (and her family) have thanked me for helping her sister become more confident and say that her sister thinks a lot of me, which I'm happy about. When parting we usually hug and kiss (peck on the cheek) each other goodbye. But a little over two years ago, things started to change slowly.

It started when the three of us were out having a drink. While my GF was at the bar (ordering our first drinks of the evening!) her sister (then single) turned to me and said "If you want to get me into bed, all you have to do is get me drunk on [name of beer removed]." We'd not been talking about sex (and up to that point never had) so it came as a total shock. When my GF returned I told her and we all laughed it off as a joke. The next Christmas my GF bought a present for me to give to her sister, just from me - the present was a gift box of the beer her sister mentioned earlier in the year. I expressed concern about the suitability of the gift, but again it was laughed off as nothing to worry about. Her sister loved it and that seemed to be that.

Since then there have been several things which my GF has noticed (as she's usually been around when they've happened), which have got us both thinking (and me concerned and my GF paranoid). These include her sister (not single from this point): Whispering to me that she wanted me (loud enough for my GF to hear), changing in front of me (only down to her underwear, GF not present but I told her), telling me what aroused her, and even as far as deliberately flashing her underwear to me when I was trying to take a photo of her and her BF for them. There have also been a lot of times (especially recently) where she has gazed at me, until I noticed at which point she'd turn away (once she'd been caught by me). Also her goodbye kisses have move closer and closer to my lips, and are now just millimetres away.

Her and her BF have just bought a house (after just under two years together), but the attention to me hasn't stopped. If anything, over the last few months it's increased.

Testing the waters

Last week I decided I wanted to try and see what on earth was going on. I was helping them out with their move one evening while my GF was at work. As I said goodbye, I hugged her and gave her a peck on the cheek as normal. I also let my hand move down her back and rest on her butt. Over the next couple of days I waited, expecting some kind of fall out which I could easily explain away "Oops, sorry! I didn't even realise!" to either her, her BF or my GF. There was nothing. Perhaps she hadn't even noticed.

The next time we met a couple of days after (with my GF), we went through the usual goodbye routine, but this time I squeezed her butt - and hard enough that she had to notice. The next day she text me thanking me for my help, but again after a few days there was nothing about my touch.

My girlfriends initial admission of her fantasy

We'd all planned to go out this weekend, and in the week or so leading up to it and kept teasing my GF. Telling her I was going to touch her intimately (my GF!) while we were out, and asking her what would happen if her sister saw. After we got home on the evening I'd squeezed her sisters butt (GF doesn't know) she seemed really turned on. I started to touch her and we ended up having sex. During sex, we were talking dirty and I said "What if your sister sees us?" My GF got even more highly aroused, and then went on to describe her sister pleasuring herself while she watched us have sex. She got even more turned on by this and I could tell by her facial expressions and the noises she made, that she wanted me to describe things in more detail.

In the fantasy, it ended up with me having sex with her sister and her sister swallowing to finish me off. The two woman never made physical contact in the fantasy! When we had finished my GF confessed that she'd thought about it for a little while before (a few weeks or so) but didn't dare express herself, for obvious reasons. We spent the next day with our heads spinning wondering what the hell had happened and if it was even ok. I eventually said it was only a fantasy and as long as we're not hurting anyone it's ok, but admitted I was still a little confused and uncomfortable. My GF kept apologising, for which she was told to stop!

The weekend

This weekend the four of us all went out for a whole day (which we have never done before) and I kept my promise to my GF. A couple of times her sister did see what I was doing, and looked at me and smiled. Over the course of the day, I also took several discrete opportunities to touch her sister (but not too intimately - a couple of gentle squeezes of her butt, gently brushing against her hand, gently squeezing her knee and her arm) while we were all together but only me and her sis. I figured if I really pushed my luck, she'd eventually say something and tell me to stop. Throughout the day she gave me the usual smiling glances, held for a couple of seconds after I made it clear that I'd noticed.

In the evening we were all sat watching the fireworks. Somehow (and with my GF and her sisters BF knowledge) her sister and I ended up sitting together with our arms round each other, holding hands. My GF had her arms around her sisters BF - until someone stood in front of him and blocked his view, but her sister and I didn't break contact. I whispered to her sister "Do you feel comfortable?" and she just smiled and nodded gently.

When we dropped her sister and BF back at home, I took two separate opportunities to hug and kiss her, and squeeze her butt really firmly. It was a sort of last gasp attempt to see if she'd say anything to anyone else. Not a thing was (or has been) said. Nothing at all. Nothing!

When we got home, my GF and I had incredibly passionate and dirty sex (involving her fantasy about her sister.) She even told me to call out her sisters name, which I begrudgingly did. This turned her on more than I have ever seen and I've never known her to be so incredibly wet. This morning, we had sex again and talked dirty about me being with another woman. I described my GF squeezing the other woman's butt. All the way through sex my GF had an expression on her face which told me exactly what she wanted me to say. I told her that the other woman was her sister and that she was touching her own sisters butt. My GF came really fast and hard after that. I have to admit that I was quite turned on by it too, though nowhere near as much as my GF.

A thank you and an apology!

I realise this has been a ridiculously long post, so sorry for that. Thank you for reading it all! Hopefully it has been clear why the the detail was necessary!

My point

Since my GF's sister hasn't mentioned my advances to anyone (even though they were only to try and figure out what her sister thought,) and since my GF confessed her secret (and really dirty) fantasy, my head has been spinning. I'm not sure what on earth is going on at the moment and I don't know what the hell to do. My GF and I will not be parting over this - I have no feelings toward that! I also don't really feel that I'd want to pursue anything with her sister - the potential implications are obvious and the potential fall out could be devastating for everyone concerned, particularly the sisters.

My questions are:

Has anyone been in a similar position and if so, what is your advice?
Is my GF's fantasy normal (or at least not uncommon)?
Why am I not as excited by this as she is?
What do I do about my GF's sister?
Lastly, WTF?!

Thank you so much in advance!

Brother - sister incest sometimes happens even though it is taboo and illegal most places. Sister - sister relationships must happen also, but I would think rarely. Sisters marrying one man in multiple marriage is probably one of the more common forms of multiple marriage. If your wife and her sister were to be together while having sex with you, they could very well go to a certain level with each other and then stop.

I think you gf's fantasy is unusual but not out of the realm of what is normal. Who knows what the underlying psychology is for her. You are possibly not as excited about it as she is because with swinging there is clear separation on what is relationship and what is play. With family, those lines can be blurred. You cannot stay away from your wife's sister without staying away from your wife.

If you want to do something and have concerns, quit throwing gasoline on the fire. Become cordial but cool with her. If you want to take it forward, first discuss it with your wife and then later both of you discuss it with her sister if its OK.

Life sometimes throws you a curve ball.

Is my GF's fantasy normal (or at least not uncommon)?
Normal is relative. Don't worry about it. Who knows what is common. People usually don't share such intimate fantasies, especially if it may violate conventional ideas of morality. There is no way of knowing if this is common, but I'm pretty sure your GF isn't alone.

Why am I not as excited by this as she is?
Why do you have to be? Do you get turned on by other's people's fantasies? Not all of them. This may be a fantasy for another man, just not you. I'm sure you are not attracted to every woman.

What do I do about my GF's sister?
Nothing. Keep the relationship cordial. She has a BF and you haven't mentioned if he is sexually open like you are. If anything, I would openly talk to her and just let her know that you were flirting a little bit, but you have no intention of taking it further. You love you GF and you don't want to complicate things.

I guess your GF's fantasy can be normal on some level. Many women like to fantasize about this stuff. I for one never did or fantasize about it. When I was married (divorce was finalized a few months ago) I never fantasized about another man, even though the sex was very seldom. My first love/first time was with my sister's husband.(I met him before my sister, broke up, then sister's friend introduced them, sister had no idea until late in the relationship that he was my 1st) after that ended, I did think about him, etc... Then I got married, and did occasionally think about him. That only lasted a few months. Even when I would see him during visits there was no flirting was going on.
After I decided to get divorced did things change. My divorce was because of a bad relationship. No sex, and when we had sex, it was borderline violent/forceful/rape…
I had to go live with my sister, who was now married to my first love, that’s when things changed. I never made any attempts. I was actually fine not being in another relationship pending my divorce. But on a drunk night, my sister dragged me into bed and we had our 1st of many 3 somes. Later I found out my sister loves watching me and her husband have sex… This led to a connection re-starting between us, and started a sexual relationship with us. Fortunately my sister gets really turned on by this, otherwise this would have ended badly for everyone… Many times she likes to just watch, then within 1-2 hrs likes having sex with him.( I make her wait, I don’t want him having sex and then immediately leaving) I on the other hand don’t get turned on by watching him, nor do I really want to have sex with him, after he’s had sex with my sister… Although, there have been a few occasions where I just need it, and will do it. I do it during our 3 ways because the atmosphere is just there… We do have very regular private 1-1 sex.
I would really make sure you GF can handle what comes with this type of experience… Plus like some one else has said, there is the issue that your GF’s sister has a Boyfriend.
It also looks like the GF’s sister is making the moves.. The GF is probably just having a fantasy, but does she want to act on it?
If you go down this route, it can become a high stress situation for everyone… So it’s worth taking the time to discuss everything in the open..

So out of interest. What become of your situation?

[Patti-here]

since this is only a fantasy I'm not very excited about it, but let me point out one thing, sibling incest is the most common type of incest there is, be it brother and or sister and sister.

Hijacking this topic because what I have to say doesn't deserve its own thread, and I need to vent. And it's so weird that such a post appeared on this forum on this night of all nights.

Had a family gathering today and it ended very awkwardly between me, my GF, my brother (9 years older), and my brother's wife (sister-in-law). I know my brother is very sexually attracted to my GF, and that's fine. It's an involuntary response and I honestly could not give a rip. However, I also feel resentment from him and his wife towards my GF and I. This also does not help the fact that my sister-in-law and I butt heads often. I am not judgmental and am extremely easy going, but trust me when I say she is a disgusting human being. She unjustifiably criticizes my GF (like what she was wearing today, which looked amazing), and I feel like she is trying to get my GF to break up with me.

My sister-in-law also squeezed my GF's butt today (this is as close as it gets to being on topic). This action was probanly fueled by jealousy and wanted to know if maybe it felt the way it looked?

A huge rift has been forming between my brother and I and I think it all has to do with my GF because I think she has had a negative impact on their marriage. I just don't know what initiated the rift, though I have an idea (three possibilities). My bro's wife is jealous of my GF? My bro is jealous of me because I am not going to end up with someone as vile as his wife? My sister-in-law resents my bro because she notices that he is attracted to my GF?

There is more to the story but it's late (and it's a very interesting one). It ended with me arguing with my sister-in-law and my GF crying on the ride home (she is not good with confrontations)

Thanks for the outlet!

Wow. What a crappy thing to have to deal with.

[Something_Awesome]

You seriously don't know the half of it. Too bad I can't reword what I wrote, but it probably has more to do with all my sister-in-law's insecurities. I have a big family and I know she wishes my family did not like my GF. This story has so much meat on it though I just rather not get into it... Just thought it was funny that this topic appeared after seeing my bro and his wife yesterday. I had not seen them for a few months til yesterday.

Those are certainly the three things that jump out at you first. I take it your SIL is not as hot as your GF, or that maybe her sex life with your brother isn't as fulfilling as yours and GFs? (You know how when the sex is great you kind of radiate "I have great sex.") The only twist I might add is the possibility your brother is just plain wants your hot GF - love triangle type thing. The odd man out doesn't have to actually have a chance with her to have the feelings of jealousy/resentment/inadequacy that go along with unsatisfied lust. (Think of stalker scenarios where those feelings are very strong for the stalker, even tho the target doesn't even know them.)

Why was GF so upset, and did you make it right for her?
