Dude seems to have forgotten he wasn't writing a mindless H doujin here this chapter (For those that somehow don't know, he makes porn), lol. The content was fine, but the way the characters acted was completely off (Casual rape and instant aheago). Maybe the author knew they were being canned and just went full mindless porn with the final chapter, can't say I blame them in that case, why not. Woulda been nice if the characters at least acted how they usually should a bit though, they didn't even feel like themselves.
