My boyfriend and I have been dating for a few years now We have an open relationship and we love having threesomes. We've had lots of threesomes before. Each year on our birthdays, we have a tradition where we tell each other a naughty fantasy we'd like to do. We don't have to agree to it-we agreed that we can say "no" if we don't want to do something and the other person won't get mad. It's my boyfriend's birthday and he's nervous about telling me his fantasy because by far the kinkiest one we've ever done. He wants to have a threesome with his sister Elizabeth and I. I think she's hot and I'm totally down for it. However, she's a librarian and her personality very much fits it-quiet and conservative. I think that there's no way she'll possibly agree. Will she come over and help fulfill our wildest fantasy yet? I hope so!
