My wife told me before we were married that she thought she had a little bi streak. But it was several years until she acted on it. We started as swingers. The wife of the first couple we played with was bi. My wife hadn't shared with them her interest in other women but during our play, the other lady asked my wife if she could kiss her. That was all it took. They ended up playing together while the guys watched for quite a while. After that, she had sex with several of the other women of the couples we meet and played with. We became friends with a swinger couple who became regulars of ours and both girls often had some play together during our get togethers. I was lucky, it was something she wanted to do.
