I want to see my wife with 2 woman at the same time. Or to watch her with a m/f couple.
I would also have her enjoy me getting to be two men, one taking me at each hole.

As many ladies around mid age start going thru menopause, and they find their libido gone would you care if you thought your man was going bi would it be OK but don't bring anything home, I'll let you know if I ever think of doing anything.
OR would you be Okay with him being bi but only on the down low.
She has finger me for our whole time together, then she started peeing me with small dildos, until one night we were relaxed and she told me she was going to make love to me. Took me with a 7" dildo and convinced me that together we were going to fine a real man to take my cherry.
Twice, first one for over 50 years. We live 2000 miles apart nether would cheat on our spouses and the time one of us was single the other one wasn't.
The second was my boss, black educated lady, but she said, and rightfully so, that it would be fun but neither of us could pull it off without guilt.
