If a guy is flirting with my lady, I'll let it go on for a while before I step in and show him the lucky man.
It might work better if she flirts with men. She can make the first move, some will come on others may not.
I have posted about my life on various posts here. My fwb is 52, 5’4 toned and amazing 36dd breasts. She is a natural nympho and has been with dozens of men of all sizes. She doesn’t dress slutty except when we may be out at certain events or places or on vacay etc. she has never been with a woman but wants to and I have been with her when she has made out with a few. One day she fucked a contractor as I was in the house and gave a valet a blowjob while we we’re having dinner. I find it a super turn on. So a few days ago I went over to see her and she was wearing her tight tanktop showing those delicious tits and tights. We fucked and had a great time. Some of the mothers in the area are jealous because i can tell by the looks they give as their husbands undress her with their eyes. Anyway she told me she went to my mechanic to get an estimate on a new tire and wanted to know if I could speak to him to see if I could get a better deal. I went to him with her and he was very accommodating and as we chatted he asked how long we were married. We said we weren’t but we are friends with benefits lol. He is 30 and african american and i could tell what she was thinking. She has been with other races and as we chatted she basically invited him over during his lunch hour for some benefits. Yesterday as we were fucking she told me he came over before I got there and they fucked. He had a nice large cock, ate her pussy well and he has agreed to do a threesome with us which she is now all wet for. I’ll keep you posted
My wife and I went through a period in which we both had other partners. She had more of them, obviously. It was a hot, hot time. It never became a problem.
