The whole story doesn't have to go that way. Just one path.
It wouldn't be an NTR slant, because Patrick is already "interested" in the fantasy to some degree based on this new update (even if he told Vika he was just browsing). He just doesn't want to do it for real.
On that path, there's no kiss pic because the kiss didn't actually happen...
Julia is just telling a hot story, creating/teasing the fantasy, without actually doing it.
There are wives that actually do that...
I certainly understand that wouldn't be appealing to people who actually want to see the sharing...
But, that path, where the wife plays into the fantasy by teasing with suggestive photos, saying something happened that really didn't, all while staying faithful, not crossing the line, that'd be a really good path...
