My wife isn't bi, always has had a dim view of bisexuality. She tried it in our 1st mfmf, didn't care for it. We gravitated towards mfm fun. I tried 'fucklicking' her while she was riding a friend, she 'really' enjoyed,lol. During the fucklicking, i kept getting his cock shoved in my mouth, wasn't bad, lol. We talked about it later. Decided to try some mmf fun. Well, that was a hit! We both had fun sharing sucking his cock, and him and her sucking mine. Been with him multiple times. She told me how hot it makes her.
Fast forward to our next mmf try. Was going pretty well, but he got too demanding, trying to hurry things up, so my wife just 'shut it down'. Well, there were 2 men with hard cocks, so I started sucking him, having a great time - he was enjoying it too.
After we left, wife was a bit angry? don't know if that the word. But her dim view of bisexuality came out, and accused me of just wanting to suck cock, asking if I was gay, and saying she'd "keep my secret". I said, hey, if it finds us cock... Don't think that helped, lol.
Anyhows, we've not had mmf fun since, or any fun with others for that matter. But, that has been due to other reasons.
She 'says' she's still onboard with some mmf fun - but she's 'particular' who that would be with, and is not very enthused about finding new candidates. Sex talk during sex, she always responds positively (cums hard!) when I mention our past mfm introduction, and other mmf fun we've had. So, guess we'll see....
