that's definitely the problem with setting up the expectation and deadline. If we assume he has a full time job and hopefully a social life, hobbies, etc. this much writing is a lot - especially 20 chapters in and trying to make it still good. The real problem he's come to is that he's refusing to push the story closer to the finish so I'm confused.
Chapter 21 might be the worst. All of those words just for Sarah/Dan to repeat the usual 'giving in to Lester' with little resistance - UNEARNED mind you. There was nothing new from Lester's end. They just easily gave in. Like wtf? Then the sex scene was routine. The only good part was the blow job. As a writer, he put himself in a corner and didn't know how to get out, so he went back to the well. Ch21 should've left Lester alone and started something new for her. Maybe he didn't want to get in the 3some right away and wanted a slight intro to it first. But that could've been done with Jesse and Dan or something. Or just move this along already.
If she was in the room with Jesse and Byron, she would've gave in because we've already established the seeds of a 3some in her mind, and the naughtiness of it all - the withdrawal from Lester - would've had her craving that next level orgasm again (assuming they'd have bigger dicks than Dan as a cherry on top). Bam, that's it. Let's go to finish line already. How the fuck is she not pregnant yet? Explain it already if she's on birth control, otherwise what are these 'precautions' she mentioned. Unless the amazing irony is that Lester's boys cant swim.
This is where Don messed up in the writing, he keeps trying to take baby steps and repeating himself and it's hurting the story immensely.
