That you wife/girlfriend liked being with a girl ? I mean, was it obvious from when you first met or was it something you discovered over time ? When my wife and I first met, it wasn't a subject that came up, I assumed she was straight and never thought about it. We hadn't been married very long maybe a couple of months, and we were going at it hot and heavy when she said oh I wish we had another girl here, which got my attention big time lol. We talked about it a bit and she told me that there were times she was attracted to women. I could tell she was serious by the way she told me, hesitant and maybe a little scared. It was years before she acted on her feelings and had sex with a woman but when she did, I could tell she felt totally fulfilled and satisfied and I was happy for her....
My wife had never been with another woman until just a few months ago when Tom's wife began joining the three of us. My wife knew I was bi and wanted to see me sucking another mans cock so she started joining Tom and I. Then his wife joined in and one evening and Carol went down on my wife while she was sucking Tom's cock and she just naturally went into a 69 position with her after Tom unloaded his cum in her mouth. It was an awesome sight for Tom and I. After watching them for about 20 minutes we got ourselves into the 69 position along side them. I wouldn't say my wife is bisexual as she doesn't crave pussy like I crave cock. She does enjoy playing with, licking, and sucking on Carol's tits but mainly craves cock.
Kind of sounds like my wife, straight with a bi option if she likes the girl and the situation is right. My wife hooked up with another girl that was on a swinger site back when we did that. The other girl was married but said her husband wouldn't be involved in any way, so my wife and her set up a lunch date to basically check each other out. The day came, they had lunch and everything went well so they drove to a park and had little make out session, nothing more. They set up another lunch date and afterwards went back to the other girls house and REALLY went at it, licking pussy and ass, fingering, sucking tits, scissoring, strap on play and I'm not sure what else. Anyway she got home before I did and I could tell she'd had a VERY good day, smiling, flushed, giggling, pussy soaking wet and horny as hell lol. That was her first really good bi experience, she had several more with the same girl and enjoyed them all but they moved so that fun time came to an end. She's been with maybe 3 other girls since then and had more hot girl sex but her first real fuckbuddy was her favorite...
