Should i agree to a threesome with his secretary?

We married young when I was sexually quite inexperienced. 2 kids later I thought the boring sex I had with my husband was normal. Then I met someone, doesn’t matter how it’s not important, he was a bit older than me but we connected so well from the start. Then one afternoon he seduced me, the sex was unbelievably out of this world. First he was massaging and kissing me all over my body, he used his fingers to bring me to orgasm several times, then moved on to use his tongue giving me quite a few more. It seemed to go on for hours I orgasmed I think twice more while he made love to me. Then when I thought it was all over he went down on me one more time and cleaned me out, giving me a final orgasm in the process. I came more times that afternoon than I had since I married my husband. A few days later he died in a car accident. My world fell apart and it was so hard as I couldn’t let my husband know why I was so upset, I ended up blaming hormones and made out I was having a really heavy period. I blamed myself for his death like it was a punishment for my being unfaithful. I was never unfaithful before or since, that was all about 25 years ago but sex with my husband has never come close and was always pretty crap. Foreplay was limited then he would climb aboard, do a lot of grunting and it was all over. He hardly ever made me cum so it became a ritual we went through once or twice a week.

Then 6 months ago I find out that for the past couple of years he’s been having an affair with his secretary, although god knows what she sees in him. We both do a lot of shouting and hollering and he begs me not to divorce him etc. So then after all these years I tell him about my little discretion, I think I just wanted to hurt him. Anyway we shout and argue some more about what a crap lover he is and finally he becomes all masterful, physically drags me to the bedroom despite my protests rips my clothes off, ties my wrists with a dressing gown cord and stuffs my knickers in my mouth to shut me up. I finally stop struggling give in to him and let him go to town on me. Finally he gives me the best sex of our marriage.

I knew though that it would be a one off so there we are faced with the dilemma of what happens next. I figured all the while they worked together he would not end the affair, even if he promised me he would so I gave him choices. He could get rid of her, but that was not an easy option as she has employment rights. He could leave his job and get another one, again not that straight forward. He could have a divorce. And one final option, the one he chose, he continues his affair but he never gets to screw me again, but 3 times a week he gives me his undivided attention for a couple of hours where he gets to massage me, kiss me hold me and give me several orgasms with his fingers, his tounge or one of several vibrators we have recently purchased. I’ve even ordered a strap on for him to use on me but it’s not arrived yet. Basically he gets to give me great sex however I choose but never gets to put his dick in me and never gets to cum when he’s with me, he can do all that with her.

So here is my dilemma, we have had this arrangement for about 6 months and for me it is a better sex life than we ever had. But it’s far from perfect and the rest of the time our marriage feels quite cold like why are we bothering. I force myself to get in the mood for our pampering sessions as I call them, but admittedly once we start he has got very good at relaxing me these days. But now he has said it might help our relationship if we change things by getting the 3 of us together for sex. He has gone on about this a lot the last few days but I don’t know if it’s a good idea.
