Chillie, that story -Lester, Sarah and Dan, ended around ch14 i.e. when the center of the illicit affair moved from the house in Chicago.
The moment DS has begun to play Lester outside that context, the story couldn’t be the same anymore and other actors need to be (imho correctly) involved to have a plausible scenario.
From that point on, the story has a trajectory that cannot be forecast, btw possible scenarios, Lester losing the control in an environment he doesn’t know - with another one taking the cherry - or Sarah completely liberated and willing vixen.
It’s the natural evolution of a story if the author wants to maintain a minimum of plausibility.
This is why lot of people are asking Otis-Sarah behind Lester, because it’s the most plausible outcome considering the description of ch26 alpha.
Caesar - I get that what you've laid out is the story you want to happen, but sometimes I wonder if we are reading the same story. Sarah isn't a vixen in the traditional sense, that's what Dan wanted originally, but he ceded that power to Lester. Name one character that Sarah has had sex with, that wasn't planned or orchestrated by Lester? Byron is the only one and she hadn't even planned on doing that and she told you in her own words the whole time she was thinking of Lester. Those aren't my hopes or desires it's what's written on the page.
Regarding the Otis/Sarah scene in ch26 - you say that it's the plausible outcome for Sarah to do this behind Lester's back and why people want it. If it had been written that Sarah decided to find/give Otis a blowjob, I would agree with you. But that's not what was written, she did it because Lester told her to, and then Lester filmed it (I'm sure we will find out why in a later chapter).
The basic premise of this story from Ch1 all thru Ch26 is that Lester is corrupting Sarah and gradually taking Dan's place.
* Lester takes her on dates and buys her things that Dan can't afford
* Lester fucks her better than Dan can
* Lester gives her a better wedding night than Dan did
* Lester shares her with others but doesn't lose control like Dan does (obvious exception being Vernon)
* Lester shows her he can earn more than Dan
* Lester shows her he can get shit done, while Dan can't find his ass if it was handed to him
* Lester buys her a better wedding ring than Dan
* Lester saves her job, which Dan couldn't do (even if Dan knew she'd lost it)
* Lester stood up for her and put Mary in her place, which Dan couldn't do
* Speculation but I assume if/when Sarah gets pregnant by Lester he will give her the son that Dan couldn't
* Again speculation but the ending of this story will be about Sarah having to decide which life she wants to lead.
With all of that setup over 26 chapters, mind you written by DS (not what fans hope or want to happen), why would anyone think the story would suddenly turn into Sarah ditching Lester and fucking every tom, dick and harry? Why any author would spend that much time and effort writing a detailed plot to suddenly just chunk it and start writing a whole new plot on chapter 27, without tying up the previous one - now that - that would be an implausible outcome.
