I have to admit that I agree with the many that thinks this story should've come to a conclusion long ago, I think it should've right about when they finally arrived in Seaside when F and Dee relocated, and maybe give us one last, bigger epilogue episode to show how Dee's career as a model took off, became a star, they live a nice life, maybe had a kid or two, and end it at that.
I think everything else since relocation has been artificial and not very organic, and definitely quite unnecessary.
A lot of people complain about the lack of swinging/sharing/NTR, but my personal opinion is that that stuff doesn't fit this kind of story in the first place, it's a vanilla romance story.
Besides, fathers don't want to picture their daughters having sex, let alone see it. Nah, a father would take his shotgun and clean it up whenever a new "suitor" for daughter would enter the picture, just to make sure nothing happen. Add to that the father in this case himself is involved with his daughter romantically and sexually, so much MUCH less likely to want to share her or none of that, that's just the realistic side of it, and in fact so realistic that even in a fantasy setting you couldn't possibly sell that idea to me that the father would be okay with it, that just don't happen.
But yeah, this should've come to an end long ago, should just wrap it up and shift all their attention to SL.
