I think they have in the past been at or near a showdown on whether their marital sex life was going to be primarily under her control. The decision at that time was that, yes, she was going to be free to decide who, where, and when she fucks.
I think David still clings to a certain ideal version of marital sex that he thinks of as "normal" and which he is waiting and hoping will re-establish itself between him and Jane someday. I think his hopes for this might have been re-kindled by the dates with the "nice woman", who probably signalled him in a thousand subtle ways that she isn't much like Jane sexually.
I don’t think the difference in Jane's and David’s viewpoints on marital sex relations is beyond their sustaining a pragmatic, working basis for living with this difference, although the sharpness of the contrast sometimes seems more vivid than at other times.
I am getting the feeling that the issues in the neighborhood of their sexual relations, including the status of her demonstrated need for outside cock(s), are up for revisiting in a mutually respectful way - and that a strong basis for an understanding going forward will emerge.
I wish these beautiful and brave people all the success in the world and I hope they can find a way to be happy together for a very long time to come.
For my selfish reasons, I would love it if their marriage would continue to accommodate Jane's intense love of occasionally acting submissive to big black daddies with huge cocks for her to suck, fuck, and have massive, shaking orgasms from.
