Threesome with my sister

It was my boyfriend's birthday a few months ago, and I treated him to a night of whatever he wanted in the bedroom. As a joke, he said he wanted a threesome with my sister. I know it was a joke, but it's been on my mind ever since, and god help me, I've actually thought about how it would happen. When we were younger, we once experimented with each other. We didn't really go to far, but we still went there. Since my boyfreind joked about it, I've been studying my sister, and I think she has supressed sexual feelings for me. All three of us are attractive, we're all attracted to each other to some extent seems, and, again god help me, I do kind of want to do this. What do I do?

  • If you are willing to try and think you can bring it up to your sister without ruining your relationship then by all means do it, I personolly would kill (not literally the expression) for a threesome with my girlfriend and her sister but even mentioning her sister is attractive will set her off so I keep my trap shut

  • Once you do something like this, you can never undo it. If you or your sister remembers this as a bad thing in the future, your relationship with your sister is shot. If it were some non-relative, it would not matter if things fell apart, but your sister? Think long and hard.

  • Bribe your sister into doing it. If she's decent she won't mind helping, Especially if it's for you. It won't hurt to try will it.

  • Do you know what the word incest means?

  • well did it ever happen?

  • It would probably end up leading to drama, but damn it would be awesome to be in the middle of that!

  • You set it up and watch to see if your sister can teach you a couple of new moves. I was 19 when a 36 yr. old former call girl took me under her wing and taught me how to really make love to a woman. We spent over five very pleasant years together. The best thing she taught me was to pay attention and ask questions. She told me that when a woman did something special, to ask her exactly what she did to do it.. to create the effect so that I could teach it to married or divorced women with limited experience and young girls who have very little or don't have any. I paid attention and learned and I did what she taught me to do. I became a teacher and got over three thousand referrals to excellent women who wanted to learn to be better at sex. Their demands forced me to stay in tip top physical shape. I'm 80 and I recently spent a year training a 26 yr. old whose husband left her because she was a 'bummer'. She was serious. She paid attention, learned to use her vaginal muscles and practiced hard. She's definitely no longer a bummer. She can wipe most men out in a couple of minutes and wear most men into the ground.

    The only threesomes I've done were with a mother and daughter. One day, the mother brought her unhappily married daughter along and asked if I'd take her on. I did them both and they came together most times after that until the mother stopped coming but the daughter came twice a week for about ten years. Of all the women that I enjoyed teaching, it was as if she was MY wife, not her husband's. She told me that she loved me and showed me that she did. She said her husband stopped cheating about six months after she started coming to see me but, by then, she was hooked on having sex with me and 'learning more skills'.

  • Stop posing as a girl? It's okay for you to be attracted to your gf's sister, but pretending to be your girlfriend is going a bit too far.
